Old Value=STEREO (Solar TErrestrial RElations Observatory) is a 2-year NASA mission employing two nearly identical space-based observatories to provide the very first, 3-D &quot;stereo&quot; images of the sun to study the nature of coronal mass ejections. These powerful solar eruptions are a major source of the magnetic disruptions on Earth and a key component of space weather, which can greatly affect satellite operations, communications, power systems, the lives of humans in space, and global climate.

STEREO is the third mission in NASA&apos;s Solar Terrestrial Probes Program. The twin observatories launched aboard a single Boeing Delta II rocket from Cape Canaveral Air Force Station, Fla., on Oct. 25, 2006, at 8:52 p.m. EDT.

STEREO is sponsored by NASA Headquarters&apos; Science Mission Directorate, Washington, D.C. NASA Goddard Space Flight Center&apos;s Solar Terrestrial Probes Program Office, in Greenbelt, Md., manages the mission, instruments and science center. The Johns Hopkins University Applied Physics Laboratory (APL), in Laurel, Md., designed and built the spacecraft and will operate the twin observatories for NASA during the mission. 

The two spacecraft are launched to drift slowly away from the Earth in opposite directions at about 10 degrees per year for the lagging spacecraft and 20 degrees per year for the leading one. Optimal longitudinal separation of about sixty degrees is achieved after two years. Afterwards the separation gradually increases beyond the design lifetime of two years with the possibility of extended mission observations at larger angles. Science instruments selected for STEREO include the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) for extreme ultraviolet (EUV), white-light coronographic, and heliospheric imaging, the STEREO/WAVES (SWAVES) interplanetary radio burst tracker, the In situ Measurements of Particles and CME Transients (IMPACT) investigation for in-situ sampling the 3-D distribution and plasma characteristics of solar energetic particles and the interplanetary magnetic field, and the PLAsma and SupraThermal Ion and Composition (PLASTIC) experiment to measure elemental and charge composition of ambient and CME plasma ions. STEREO data recorded and stored onboard each spacecraft will be downlinked through the NASA Deep Space Network on a daily schedule. Real-time space weather data will be continuously transmitted through a separate beacon system to NASA and non-NASA receiving stations.

    <skos:definition xml:lang="en">STEREO (Solar TErrestrial RElations Observatory) is a 2-year NASA missionemploying two nearly identical space-based observatories to provide the veryfirst, 3-D &apos;stereo&apos; images of the sun to study the nature of coronal massejections. These powerful solar eruptions are a major source of the magneticdisruptions on Earth and a key component of space weather, which can greatlyaffect satellite operations, communications, power systems, the lives of humansin space, and global climate.STEREO is the third mission in NASA&apos;s Solar Terrestrial Probes Program. Thetwin observatories launched aboard a single Boeing Delta II rocket from CapeCanaveral Air Force Station, Fla., on Oct. 25, 2006, at 8:52 p.m. EDT.STEREO is sponsored by NASA Headquarters&apos; Science Mission Directorate,Washington, D.C. NASA Goddard Space Flight Center&apos;s Solar Terrestrial ProbesProgram Office, in Greenbelt, Md., manages the mission, instruments and sciencecenter. The Johns Hopkins University Applied Physics Laboratory (APL), inLaurel, Md., designed and built the spacecraft and will operate the twinobservatories for NASA during the mission.The two spacecraft are launched to drift slowly away from the Earth in oppositedirections at about 10 degrees per year for the lagging spacecraft and 20degrees per year for the leading one. Optimal longitudinal separation of aboutsixty degrees is achieved after two years. Afterwards the separation graduallyincreases beyond the design lifetime of two years with the possibility ofextended mission observations at larger angles. Science instruments selectedfor STEREO include the Sun Earth Connection Coronal and HeliosphericInvestigation (SECCHI) for extreme ultraviolet (EUV), white-lightcoronographic, and heliospheric imaging, the STEREO/WAVES (SWAVES)interplanetary radio burst tracker, the In situ Measurements of Particles andCME Transients (IMPACT) investigation for in-situ sampling the 3-D distributionand plasma characteristics of solar energetic particles and the interplanetarymagnetic field, and the PLAsma and SupraThermal Ion and Composition (PLASTIC)experiment to measure elemental and charge composition of ambient and CMEplasma ions. STEREO data recorded and stored onboard each spacecraft will bedownlinked through the NASA Deep Space Network on a daily schedule. Real-timespace weather data will be continuously transmitted through a separate beaconsystem to NASA and non-NASA receiving stations.Group: Platform_Details   Entry_ID: STEREO B   Group: Platform_Identification      Platform_Category: Solar/Space Observation Satellites      Short_Name: STEREO B      Long_Name: Solar Terrestrial Relations Observatory B   End_Group   Group: Synonymous_Platform_Names      Short_Name: STEREO Lead      Short_Name: STEREO West      Short_Name: Solar Terrestrial Relations Observatory B      Short_Name: 29511      Short_Name: 2006-047B   End_Group   Group: Platform_Associated_Instruments      Short_Name: IMPACT      Short_Name: PLASTIC      Short_Name: SECCHI      Short_Name: SWAVES   End_Group   Creation_Date: 2007-02-13   Online_Resource: https://www.nasa.gov/mission_pages/stereo/main/   Online_Resource: https://stereo.gsfc.nasa.gov/   Online_Resource: https://stereo.jhuapl.edu/   Online_Resource: https://stereo-ssc.nascom.nasa.gov/    Sample_Image: https://stereo.jhuapl.edu/gallery/images/artistConcepts/tn/PanelsDeploy_tn.jpg   Group: Platform_Logistics      Launch_Date: 2006-10-26      Launch_Site: Cape Canaveral/Kennedy Space Center, USA      Design_Life: 2 years      Primary_Sponsor: USA/NASA      Primary_Sponsor: Johns Hopkins/APL   End_GroupEnd_Group</skos:definition>

Old Value=The Fokker F27 Friendship is a turboprop airliner designed and built by the Dutch aircraft manufacturer Fokker.

Design of the Fokker F27 started in the 1950s as a replacement to the successful DC-3 airliner. The manufacturer evaluated a number of different configurations before finally deciding on a high wing twin Rolls-Royce Dart engine layout with a pressurised cabin for 28 passengers.

The first prototype, registered PH-NIV, first flew on 24 November 1955. The second prototype and initial production machines were 3 ft (0.9 m) longer, addressing the first aircraft&apos;s slightly tail-heavy handling and also providing space for more (32) passengers. These aircraft also used the more powerful Dart Mk 528 engine. The first production model, the F27-100, was delivered to Aer Lingus in September 1958.

In 1956 Fokker signed a licensing deal with the US aircraft manufacturer Fairchild for the latter to construct the F27 in the USA. The first U.S.-built aircraft flew on 12 April 1958. Fairchild also independently developed a stretched version, called the FH-227.

At the end of the Fokker F27s production in 1987, 793 units had been built (including 207 in the USA by Fairchild), which makes it the most successful western European civil turboprop airliner.

Many aircraft have been modified from passenger service to cargo or express-package freighter roles.

In the early 1980s, Fokker developed a successor to the Friendship, the Fokker 50. Although based on the F27-500 airframe, the Fokker 50 is virtually a new aircraft with Pratt &amp; Whitney Canada engines and modern systems. Its general performance and passenger comfort were improved over the F27.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

The first satellite to be developed, CBERS-1, was launched with great success by the Chinese Long March 4B launcher, from the Taiyuan Launch Base, on Oct. 14, 1999. Launch occurred at 1:15 AM (Brasilia local time).

Two modules compose the satellite. The first one is the payload module, where 3 cameras are located (CCD Camera, IRMSS Camera and WFI Camera) and a Transponder for the Brazilian Environmental Data Collection System. The second one is the service module, containing the equipment for power supply, control, telecommunications and remaining functions necessary to the satellite operation.

Its orbit is Helios-synchronous, at a 778 km altitude. It performs about 14 revolutions a day and obtains a complete coverage of the Earth in 26 days.

Cosmos-1500 was a precursor to the operational Russian Okean (&apos;Ocean&apos;) series of oceanographic remote sensing missions. Cosmos-1500 was launched into a 649 x 679 km orbit at 82.6 deg. inclination. The Cosmos-1500 tested new sensors and methods of data collection and processing. Cosmos-1500 had the capability of overlapping and processing images from its sensors. Data from Cosmos-1500 were sent directly to ships or automated data receiving stations and was applied in navigation in northern oceans. The instrument complement was highlighted by an all-weather X-band Side-Looking Real Aperature radar (SLRAR) operating at 9.5 GHz. other instruments included a multispectral scanner (MSL), a scanning high-frequency radiometer (SHF), and transponders for collecting data from ice and buoy transmitters.Group: Platform_Details   Entry_ID: COSMOS 1500   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: COSMOS      Short_Name: COSMOS 1500   End_Group   Group: Synonymous_Platform_Names      Short_Name: COSMOS 1500   End_Group   Group: Orbit      Orbit_Inclination: 82.5 degrees       Period: 95.8 min        Perigee: 546 km        Apogee: 565 km     End_Group   Creation_Date: 2007-09-12   Online_Resource: http://www.n2yo.com/satellite.php?s=14372   Group: Platform_Logistics      Launch_Date: 1983-09-28        Primary_Sponsor: Russia   End_GroupEnd_Group</skos:definition>

Old Value=The Piper PA-23, named Apache and later Aztec, was an American twin-engined monoplane, the first twin-engine aircraft built by Piper Aircraft.

Originally to be named the &quot;Twin-Stinson&quot; and designed as a four-seater low-wing all-metal monoplane with a twin tail, the prototype first flew 2 March 1952. The prototype was then named the PA-21 to conform to Piper&apos;s numerical nomenclature[1] It was redesigned with a single vertical stabilizer and an all-metal rear fuselage and renamed to Apache 150 when it entered production in 1954; 1,231 were built. In 1958, the Apache 160 was produced by upgrading the engines to 160 hp (119 kW), and 816 were built before being superseded by the Apache 235, which went to 235 hp (175 kW) engines and swept tail surfaces (119 built).

Declining sales of the Apache prompted the redesign dubbed PA-23-250 Aztec, with 250 hp (186 kW) Lycoming. The first models were delivered with O-540 Lycoming carburetor engines. These first models came in a five-seat configuration which became available in 1959. The later models of the Aztec were equipped with IO-540 fuel-injected engines and six-seat capacity, and continued in production until 1982. There were also turbocharged versions of the later models, which were able to fly at higher altitudes.

New Value=The Piper PA-23, named Apache and later Aztec, was an American twin-engined monoplane, the first twin-engine aircraft built by Piper Aircraft.

Originally to be named the &quot;Twin-Stinson&quot; and designed as a four-seater low-wing all-metal monoplane with a twin tail, the prototype first flew 2 March 1952. The prototype was then named the PA-21 to conform to Piper&apos;s numerical nomenclature[1] It was redesigned with a single vertical stabilizer and an all-metal rear fuselage and renamed to Apache 150 when it entered production in 1954; 1,231 were built.

text: Remotely operated vehicle (ROV) Deep Discoverer is owned by the NOAA Office of Ocean Exploration and Research and was built and continues to be maintained and operated by the Global Foundation for Ocean Exploration (GFOE) . Also known as “D2,” the vehicle is operated off NOAA Ship Okeanos Explorer with its sister vehicle, Seirios.

Capable of diving to depths of 3.7 miles (6,000 meters), D2 provides scientists unprecedented access to the deep ocean. The main capability of Deep Discoverer is the ability to capture high-definition video, with the vehicle’s primary camera able to zoom in on a three-inch long organism from 10 feet away. D2’s 20 LED lights provide 150,000 lumens of light, illuminating the otherwise dark depths of the ocean.

Equipped with two manipulator arms, Deep Discoverer is capable of collecting both biological and geological samples. The ROV is also outfitted with a variety of sensors to measure parameters such as salinity, water temperature, depth, and dissolved oxygen, providing additional information about the deep-ocean environment. Also available are five 1.7-liter Niskin bottles for water collection and a rotary suction sampler with six 4-liter sample jars for collecting more delicate biological samples.

As a “remotely” operated vehicle, D2 carries no passengers. The vehicle is connected to Seirios and Okeanos Explorer via a long cable and is piloted by GFOE engineers on the ship. Thanks to telepresence technology, live video from D2 travels from the seafloor to the ship and then via satellite connection to scientists located on shore who use the real-time video to provide guidance to the pilots on where to go and which samples to collect. The live video is also broadcast to the Internet, allowing members of the public to join in on D2’s adventures.

From delivering stunning high-definition video and gathering physical data about surrounding waters to allowing the collection of biological and geological samples, D2 is delivering data needed by scientists to better understand an ecosystem in its entirety, meaning we can make better decisions about an area&apos;s management as well as its protection.

The CALIPSO satellite was developed to help scientists answer significant questions and provide new information about the effects of clouds and aerosols (airborne particles) on changes in the Earth&apos;s climate. Understanding these components will provide the international science community with a more comprehensive data set that is essential for a better understanding of the Earth&apos;s climatic processes. Accurate climate model predictions will provide international and national leaders accurate information to make more informed policy decisions about global climate change.

CALIPSO flies a 3-channel lidar with a suite of passive instruments in formation with Aqua to obtain coincident observations of radiative fluxes and atmospheric conditions. This enables new observationally based assessments of the radiative effects of aerosol and clouds that will greatly improve out ability to predict future climate change.

CloudSat also flies in formation with CALIPSO to provide a comprehensive characterization of the structure and composition of clouds and their effects on climate under all weather conditions. This comprehensive set of measurements is essential for accurate quantification of global aerosol and cloud radiative effects to understand their role in formation and variation of Earth&apos;s climate. This is a cooperative mission with France.

This is a cooperative mission with France.For more information on CALIPSO, see:https://www-calipso.larc.nasa.gov/Group: Platform_Details   Entry_ID: CALIPSO   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: EOS (Earth Observing System)      Short_Name: CALIPSO      Long_Name: Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations   End_Group   Group: Platform_Associated_Instruments      Short_Name: WFC      Short_Name: CALIOP      Short_Name: IIR   End_Group   Group: Orbit      Orbit_Altitude: 705 km      Orbit_Inclination: 98.2 degrees      Period: 99 minutes      Repeat_Cycle: 16 days      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-04-17   Online_Resource: https://www-calipso.larc.nasa.gov   Online_Resource: https://eosweb.larc.nasa.gov/project/calipso/calipso_table   nline_Resource: https://www.nasa.gov/mission_pages/calipso/   Group: Platform_Logistics      Launch_Date: 2006-04-28      Launch_Site: Vandenberg Air Force Base, USA      Design_Life: 3 years      Primary_Sponsor: USA/NASA      Primary_Sponsor: FRANCE/CNES      Primary_Sponsor: Alcatel   End_GroupEnd_Group</skos:definition>

    <skos:prefLabel xml:lang="en">ERS-1</skos:prefLabel>
    <skos:definition xml:lang="en">The first European Remote Sensing Satellite ERS-1, launched on 17 July1991 at 01.46 UTC, operates in a sun-synchronous, near-polar orbit atan altitude of 785 km and an inclination of 98.5 degrees, known as thereference orbit.ERS-1 was conceived as an orbiting platform that would be capable ofmeasuring, on a global scale, the Earth&apos;s atmospheric and surfaceproperties with a high degree of accuracy. In fact it uses advancedmicrowave techniques to collect global measurements and images (muchof the data are collected from remote areas such as the southernoceans and the Antarctic) independently of time of day and weatherconditions. It also undertakes the measurement of many parameters thatare not covered by existing satellite systems, including those of seastate, sea surface winds, ocean circulation and sea/ice levels.Satellite characteristics:--------Platform: based on the SPOT Multimission PlatformPower supply: 4 x 24 Ah batteries; 1.8 kW from solar arrayAttitude control:  3-axis stabilised earth pointing, withoption of 9.5 degrees offset in Roll-Tilt Mode (RTM)Total mass:  2400 kg (at beginning of mission)Overall length: 11.8 mSolar array: 11.7 m x 2.4 mSAR antenna: 10.0 m x 1.0 mScatterometer antennas: fore/aft 3.6 m x 0.25 m; mid: 2.3 mx 0.35 mRadar Altimeter antenna: 1.2 m diameterDesign lifetime: 2-3 years---------ERS-1 carries on-board a number of instruments consisting of a coreset of active microwave sensors supported by additional, complementaryinstruments: the Active Microwave Instrument (AMI), which combines aSynthetic Aperture Radar (SAR) operating in image or wave mode and awind scatterometer, the Radar Altimeter (RA), the Along-Track ScanningRadiometer and Microwave Sounder (ATSR), the Precise Range andRange-rate Equipment (PRARE) and Laser Retroreflectors (LRR).The primary objective of the ERS-1 mission is the monitoring of oceansand sea ice providing essential data for:- improved representation of oceans/atmosphere interactionsin climatic models- major advances in the knowledge of ocean circulation andtransfer of energy- more reliable estimates of the mass balance of the Arcticand Antarctic ice sheets- better monitoring of pollution and dynamic coastalprocesses- improved detection and management of land use changeThe ability of ERS-1 to acquire vast global data sets of ocean,atmosphere, ice and land phenomena contributes to the following fieldsof study:- Ocean/Ice: ocean circulation, global wind/waverelationships, sea ice and iceberg monitoring, etc.- Physical Earth: accurate determination of the oceangeoid, forestry, glaciology, geology and agriculturestudies, etc.- Climate: contribution to the World Climate ResearchProgramme and to the World Ocean Circulation Experiment- Weather and Sea: short and medium-term weatherforecasting, sea surface state forecasting, wind speed anddirection, location of pelagic fish through the monitoringof temperature frontsRelation between ERS-1 instruments and missionobjectives------------------------------------------------------------Weather forecasting: AMI wind modeSea-state forecasting: AMI, wave and wind modesOffshore activity: Altimeter, ATSR, AMI in wave and windmodesShip routing: Altimeter, ATSR, AMI in wave and wind modesFisheries (fish location):  (Altimeter), (ATSR), AMI inwind modeSea and iceberg monitoring:  Altimeter, ATSR, AMI in imagemodeOil and pollution detection: ATSR, AMI in image modeCoastal process: ATSR, AMI in image modeLand applications: (Altimeter), ATSROcean circulation: Altimeter(1), ATSR, (AMI in wave mode)Ocean tides: Altimeter(2)Wind fields(3): Altimeter, AMI (in image mode), in wave andwind modeWave fields(3): Altimeter, AMI (in image mode), in wave andwind modePolar oceans: Altimeter, ATSR, AMI in all modes.Land ice: Altimeter, AMI (in image mode)Sea-surface temperature: ATSRMarine biology: (ATSR)------------------------------------------------------------( ) indicates limited applicability(1) For large-scale circulation, accurate orbitdetermination over short arcs is required(2) For solar tides, measurements from other satellites incomplementary orbits are required(3) The altimeter and active microwave instrumentation aremutually supportive in deriving the wind and wave fieldsThe complexity of the ERS-1 mission, which effectively consists of acombination of several different missions, requires a very carefulapproach when planning the mission operations. Taking into account thedifferent mission objectives, and attempting to satisfy them in aquasi-optimal way in the course of ERS-1&apos;s lifetime, has held to thedefinition of phases of activity during the mission:- Phase 0: Orbit acquisition, initial switch-on andfunctional check-out (2 weeks after the launch)- Phase A: The Commisioning phase, using a 3 day repeatcycle (25 July 1991-10 December 1991)- Phase B : The first ice phase, using a 3 day repeat cycle (28 December 1991-1 April 1992)- Phase R: The Roll-Tilt phase, using a 35 day repeat cycle (2 April 1992-14 April 1992)- Phase C: The first multi-disciplinary phase, using a 35day repeat cycle (14 April 1992-23 December 1993)- Phase D: The second ice phase, using a 3 day repeat cycle (23 December 1993-10 April 1994)- Phase E: The first geodetic phase, using a 172 day repeatcycle (10 April 1994-28 September 1994)- Phase F: The second Geodetic Phase, using a 172 dayrepeat cycle (28 September 1994-21 March 1995)- Phase G: The second Multi-Disciplinary Phase, using a 35day repeat cycle (21 March 1995-10 March 2000)In the first half of April 1992, the satellite was operated in aRoll-tilt-mode (RTM) to allow SAR imaging at a different viewangle. In fact by rotating the satellite body around its velocityvector (so-called &apos;Roll-tilt mode&apos;) the angle at which all theinstruments look at the Earth can be varied. This allowsexperimentation with the SAR at an incidence angle of 35 degreesinstead of the standard 23 degrees, thereby permitting analysis of atotally different set of signatures from objects on the Earth&apos;ssurface, including in particular vegetation.Related URL:The ERS Missions: http://earth.esa.int/ersERS-1 Design: http://earth.esa.int/ers/satconcFor any query, please refer to:ESA/ESRIN Earth Observation Help Deskhttp://earth.esa.intGroup: Platform_Details   Entry_ID: ERS-1   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: ERS Earth Resource Satellite      Short_Name: ERS-1      Long_Name: European Remote Sensing Satellite-1   End_Group   Group: Synonymous_Platform_Names      Short_Name: ERS-1   End_Group   Group: Platform_Associated_Instruments      Short_Name: ATSR      Short_Name: RA      Short_Name: SAR      Short_Name: AMI   End_Group   Group: Orbit      Orbit_Altitude: 782 to 785 km      Orbit_Inclination: 98.52 deg      Period: 100 min      Repeat_Cycle: 3-day, 35-day and 176-day      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-09-14   Online_Resource: http://earth.esa.int/ers/satconc/   Online_Resource: http://earth.esa.int/ers/   Online_Resource: http://www.astronautix.com/craft/ers12.htm   Sample_Image: http://earth.esa.int/icons/eeo/_ers-1_fully_deployed.gif   Group: Platform_Logistics      Launch_Date: 1991-07-17      Launch_Site: Kourou, French Guiana      Design_Life: 2-3 YRS      Primary_Sponsor: ESA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">Space Transport System STS-62Mission Objectives:The 14-day mission is the latest in a series of ExtendedDuration Orbiter (EDO) flights which will provide additionalinformation for on-going medical studies that assess the impactof long-duration spaceflight, 10 or more days, on astronauthealth, identify any operational medical concerns and testcountermeasures for the adverse effects of weightlessness onhuman physiology.The United States Microgravity Payload (USMP) will be making itssecond flight aboard the Space Shuttle. The USMP flights areregularly scheduled on Shuttle missions to permit scientistsaccess to space for microgravity and fundamental scienceexperiments which cannot be duplicated on Earth and provide thefoundation for advanced scientific investigations that will bedone on the international space station.The Office of Aeronautics and Space Technology (OAST-2) payloadcontains six experiments that will obtain technology data tosupport future needs for advanced satellites, sensors,microcircuits and the space station. Data gathered by the OAST-2experiments could lead to satellites and spacecraft that arecheaper, more reliable and able to operate more efficiently.STS-62 will help scientists calibrate sensitive ozone- detectinginstruments with the sixth flight of the Shuttle SolarBackscatter Ultraviolet (SSBUV) Instrument. This highlycalibrated tool is used to check data from ozone-measuringinstruments on free-flying satellites -- NASA&apos;s Total OzoneMapping Spectrometer (TOMS) and Upper Atmosphere ResearchSatellite (UARS) and the National Oceanic and AtmosphericAdministration NOAA-9 and NOAA-11 satellites.The Protein Crystal Growth (PCG) experiments and the CommercialProtein Crystal Growth (CPCG) experiments aboard Columbia willhelp scientists understand the growth of crystals to study thecomplex molecular structures of important proteins. By knowingthe structure of specific proteins, scientists can design newdrug treatments for humans and animals and develop new or betterfood crops.NASA&apos;s efforts in the important field of biotechnology arerepresented by the fourth flight of the Physiological SystemsExperiment which is designed to evaluate pharmaceutical,agricultural or biotechnological products, and the first flightof the Biotechnology Specimen Temperature Controller (BSTC),designed to test the performance of a temperature control devicebeing developed for use with the Bioreactor, a cell- culturegrowth device. Also flying again on the Shuttle is theCommercial Generic Bioprocessing Apparatus (CGBA) payload whichwill support more than 15 commercial life science investigationsthat have application in biomaterials, biotechnology, medicineand agriculture.The Middeck 0-Gravity Dynamics Experiment (MODE) will make itssecond flight on STS-62. MODE investigates how the microgravityof space flight influences the behavior of large spacestructures. The MODE test article can be configured in differentshapes typical of space structural forms-- the truss of a spacestation, for example -- to help engineers develop and verify ananalytical modeling capability for predicting the linear andnonlinear modal characteristics of space structures in amicrogravity environment. MODE also will gather forcemeasurements of nominal, crew-induced disturbance loads on theShuttle.Astronauts will demonstrate a new magnetic end effector andgrapple fixture design for the Shuttle&apos;s Canadian-built robotarm that engineers believe will increase the arm&apos;s dexterity andalignment accuracy, provide operators with a sense of touch andallow the use of more compact &apos;handles&apos; on satellites and otherShuttle payloads.Additional information available at&apos;http://science.ksc.nasa.gov/shuttle/missions/sts-62/mission-sts-62.html&apos;[Summary provided by NASA]</skos:definition>

text: Between the first launch on April 12, 1981, and the final landing on July 21, 2011, NASA&apos;s space shuttle fleet -- Columbia, Challenger, Discovery, Atlantis and Endeavour -- flew 135 missions, helped construct the International Space Station and inspired generations. NASA&apos;s space shuttle fleet began setting records with its first launch on April 12, 1981 and continued to set high marks of achievement and endurance through 30 years of missions. Starting with Columbia and continuing with Challenger, Discovery, Atlantis and Endeavour, the spacecraft has carried people into orbit repeatedly, launched, recovered and repaired satellites, conducted cutting-edge research and built the largest structure in space, the International Space Station. The final space shuttle mission, STS-135, ended July 21, 2011 when Atlantis rolled to a stop at its home port, NASA&apos;s Kennedy Space Center in Florida.

As humanity&apos;s first reusable spacecraft, the space shuttle pushed the bounds of discovery ever farther, requiring not only advanced technologies but the tremendous effort of a vast workforce. Thousands of civil servants and contractors throughout NASA&apos;s field centers and across the nation have demonstrated an unwavering commitment to mission success and the greater goal of space exploration.

text: Swarm is the fifth Earth Explorer mission approved in ESA&apos;s Living Planet Programme, and was successfully launched on 22 November 2013.

As part of the Third Party Missions programme, the e-POP instrument of the Canadian Space Agency&apos;s CASSIOPE mission joined the constellation in February 2018.

The research objectives of the Swarm mission is to provide the best-ever survey of the geomagnetic field and its temporal evolution as well as the electric field in the atmosphere using a constellation of 3 identical satellites carrying sophisticated magnetometers and electric field instruments.

    <skos:definition xml:lang="en">- Spacecraft Brief Description -The GEOdetic SATellite (GEOSAT) was a dedicated US Navy military oceanographicsatellite consisting of a radar altimeter designed to obtain closely spaced,precise mapping of the earth&apos;s geoid over the ocean. On November 8, 1986, thesatellite was moved into an Exact Repeat Mission (ERM) orbit with a repeatcycle of 17.05 days. The GEOSAT mission was originally managed by the Office ofNaval Research (ONR). During the development phase, the program responsibilitywas transferred to the Naval Electronics Systems Command, now called the Spaceand Naval Warfare Systems Command (SPAWAR) in Washington, D.C. The AppliedPhysics Laboratory (APL) was the prime contractor for the spacecraft and radaraltimeter and performed spacecraft command and control operations and collectedthe satellite data. The data was distributed to the Naval Surface WeaponsCenter (NSWC), the Naval Ocean Research and Development Activity (NORDA), andNOAA. An arrangement was made with the National Ocean Service of NOAA to obtainthe classified GEOSAT geophysical data records (GDR) providing wind, wave andsea-level products and made available to the user community. NASA obtainedGEOSAT data for extensive waveform modeling and ice sheet research.The basicstructure of the GEOSAT is similar to the GEOS-3 satellite: The design consistsof a conical structure below the core for the structural attachment of thevelocity control system. The GEOSAT attitude control subsystem was designed topoint the radar altimeter to within 1 degree of nadir 98 percent of the time.The system components were a 20-foot scissors boom with 100-pound end mass,redundant momentum wheels for roll and yaw stiffness, and pitch and rollattitude control thrusters. Attitude sensing was provided through the use ofthree digital sun-attitude detectors and a three-axis vector magnetometer.Spacecraft command was accomplished via a VHF uplink from the APL groundstation. The telemetry subsystem consisted of two S-band transmitters, two taperecorders, and two encryption units. The GEOSAT was equipped with two Odeticsdual-track high-density tape recorders that independently recorded the 10.205kbps telemetry stream and played it back at 833 kbps for transmission to theground. The GEOSAT also included redundant Doppler beacons for continuoustracking by a network of ground stations within the Defense Mapping Agency(DMA) and for a source of accurate timing to the radar altimeter and thetelemetry subsystem. A C-band transponder was also included on GEOSAT.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

Due to the success of CBERS-1 and 2, the two governments decided, in November 2002, to give continuity to the CBERS program by signing a new agreement for the development and launch of two more satellites, CBERS-3 and 4.

Brazilian participation in this program will be enlarged up to 50%, thus taking Brazil to a condition of equality with its partner. CBERS-3 is expected to be launched in 2009, CBERS-4 in 2011.

CBERS-3 and 4 satellites represent an evolution of CBERS-1 and 2. Four cameras will be present in the payload module, with improved geometrical and radiometric performance.

They are: PanMux Camera-PANMUX, Multi-spectral Camera-MUXCAM, Scanning Medium Resolution Scanner-IRSCAM and Wide Field Imaging Camera-WFICAM.

The orbits of the two satellites will be the same as for CBERS-1 and 2.

    <skos:definition xml:lang="en">In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &apos;Compass&apos;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.</skos:definition>

text: The NASA Langley Research Center and University of Wisconsin Regional Air Quality Modeling System (RAQMS) is used to estimate the tropospheric ozone budget over east Asia during the NASA Global Tropospheric Experiment (GTE) Transport and Chemical Evolution over the Pacific (TRACE-P) mission. The computed ozone budget explicitly accounts for stratosphere/troposphere exchange (STE) and in situ ozone production using on-line chemical calculations. The east Asian O3 budget is computed during the period from 7 March to 12 April 2001. Gross formation dominates STE by a ratio of 7 to 1 in east Asia during TRACE-P. However, this ratio is strongly influenced by altitude of the tropopause. Approximately 30% of the ozone that is advected across the tropopause over east Asia is subsequently advected out over the western Pacific within the upper 4 km of the troposphere by the Japan jet. The average net photochemical production (gross formation-gross destruction) within the regional domain is 0.37 Tg d−1 or 7% of the average flux at the eastern boundary of the domain during the TRACE-P time period. The budget analysis shows a very close balance between sources and sinks within the RAQMS regional domain during the TRACE-P time period. This balance results in very small average accumulation (∼1 Tg) of O3 in the east Asian region and very little net export averaged over the period (0.03 Tg d−1). The low ozone export from east Asia predicted by RAQMS during TRACE-P is a consequence of relatively high dry deposition rates, which are 37% of the gross ozone formation (1.469 Tg d−1) within the TRACE-P regional domain.

    <skos:definition xml:lang="en">[Source: National Space Science Data Center, http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1978-042A ]DMSD 5D-1/F3 was one of a series of meteorological satellites developed and operated by the Air Force under the Defense Meteorological Satellite Program (DMSP). This program, previously known as DAPP (Data Acquisition and Processing Program), was classified until March 1973. The objectives of this program were to provide global visual and infrared cloudcover data and specialized environmental data to support Department of Defense requirements. Operationally, the program consisted of two satellites in sun-synchronous polar orbits, with the ascending node of one satellite in early morning and the other at local noon. The 5.4-m-long spacecraft was separated into four sections: (1) a precision mounting platform (PMP) for sensors and equipment requiring precise alignment; (2) an equipment support module (ESM) containing the electronics, reaction wheels, and some meteorological sensors; (3) a reaction control equipment (RCE) support structure (including the third-stage motor and hydrazine reaction control system); and (4) a 9.29-sq-m solar cell panel. The spacecraft stabilization was controlled by a combination flywheel and magnetic control coil system so sensors could be maintained in the desired &apos;earth-looking&apos; mode. One feature was the precision-pointing accuracy of the primary imager to 0.01 deg provided by a star sensor and an updated ephemeris navigation system. This allowed automatic geographical mapping of the digital imagery to the nearest picture element. The operational linescan system (OLS), built by Westinghouse, was the primary data acquisition system that provided real-time or stored, multi-orbit, day-and-night visual and infrared imagery of clouds, and provided with the data calibration, timing, and other auxiliary signals to the spacecraft for digital transmission to the ground. A supplementary meterological sensor, the special sensor H (SSH), a step-scanning radiometer, was the infrared temperature-humidity-ozone sounder. Either recorded or real-time data were transmitted to ground-receiving sites by two redundant S-band transmitters. Recorded data were read out to tracking sites located at Fairchild AFB, Wash., and Loring AFB, Maine, and relayed by SATCOM to Air Force Global Weather Central, Offutt AFB, Nebraska. Real-time data were read out at mobile tactical sites located around the world. A more complete description of the satellite can be found in the report, D. A. Nichols, &apos;The Defense Meteorological Satellite Program,&apos; Optical Engineering, v. 14, n. 4, July-August 1975.

    <skos:definition xml:lang="en">The QuickBird satellite is the first in a constellation of spacecraft thatDigitalGlobe is developing that offers highly accurate, commercialhigh-resolution imagery of Earth. QuickBird&apos;s global collection of panchromaticand multispectral imagery is designed to support applications ranging from mappublishing to land and asset management to insurance risk assessment.Today, DigitalGlobe&apos;s QuickBird is the only spacecraft able to offer sub-meterresolution imagery, industry-leading geolocational accuracy, large on-boarddata storage, and an imaging footprint 2 to 10 times larger than any othercommercial high-resolution satellite.QuickBird was designed and built by our strategic partners, Ball Aerospace &amp;Technologies Corp., Kodak, and Fokker Space, all leaders in their fields. Byutilizing proven technology from each supplier, we have developed astate-of-the-art, satellite system built from space-qualified components. Thissystem successfully meets DigitalGlobe&apos;s demanding performance requirements forhigh image quality, robust image collection, and long mission life.Group: Platform_Details   Entry_ID: QUICKBIRD   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: QUICKBIRD      Long_Name: DigitalGlobe&apos;s QuickBird   End_Group   Group: Synonymous_Platform_Names      Short_Name: Quickbird   End_Group   Group: Orbit      Orbit_Altitude: 450 km      Orbit_Inclination: 98 degree      Repeat_Cycle: 2-3 days      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-11-28   Online_Resource: http://www.digitalglobe.com/index.php/85/QuickBird   Sample_Image: http://www.digitalglobe.com/image.php?id=93   Group: Platform_Logistics      Launch_Date: 2001-10-18      Launch_Site: Vandenberg Air Force Base, USA      Primary_Sponsor: DigitalGlobe   End_GroupEnd_Group</skos:definition>

Old Value=Prototype Regional Observing and Forecasting Service (PROFS) is a program responsible for improving local weather service capability through application of recent technological advances in high speed communication and computers. This program has worked closely with the National Weather Service (NWS) and the National Earth Satellite Service (NESS) to develop a highly sophisticated system (Brown, 1983) which integrates information from radar, satellites, national weather circuits, and a network of 22 automated surface observing stations spread over the northern Front Range and the eastern plains of Colorado.  That network, hereafter referred to as the mesonet, provides real-time wind, temperature, humidity, pressure, rainfall, isolation and visual range data, offering the forecaster details of meteorological fields unavailable from other sources.

text: The U.S. Navy GEOdetic SATellite (GEOSAT) was launched on March 12, 1985, into an 800-km, 108-deg inclination orbit. It carried an altimeter that was capable of measuring the distance from satellite to sea surface with a relative precision of about 5 cm. Following a classified mission for the Navy, GEOSAT’s scientific Exact Repeat Mission (ERM) began on November 8, 1986. During the ERM, GEOSAT was in a 17.05-day repeat orbit. In this orbit, the satellite passed the same point on the Earth every 17.05 days to gather important information on sea level change and ocean variability.

When the ERM ended in January 1990 from failure of both its on-board tape recorders, more than three years of precise altimeter data were available to the scientific community. The studies made using GEOSAT data are numerous and the GEOSAT data set is regarded as a milestone in both satellite oceanography and satellite geodesy.

New Value=GLONASS or &quot;Global Navigation Satellite System&quot;, is a space-based satellite navigation system operating in the radionavigation-satellite service. It provides an alternative to GPS and is the second navigational system in operation with global coverage and of comparable precision.

Manufacturers of GPS devices say that adding GLONASS made more satellites available to them, meaning positions can be fixed more quickly and accurately, especially in built-up areas where the view to some GPS satellites is obscured by buildings. Smartphones generally tend to use the same chipsets and the versions used since 2015 receive GLONASS signals and positioning information along with GPS. Since 2012, GLONASS was the second most used positioning system in mobile phones after GPS. The system has the advantage that smartphone users receive a more accurate reception identifying location to within 2 meters.</skos:changeNote>

New Value=The NEutrino Mediterranean Observatory—Submarine Network 1 (NEMO-SN1) seafloor observatory is located in the central Mediterranean Sea, Western Ionian Sea, off Eastern Sicily (Southern Italy) at 2100-m water depth, 25 km from the harbor of the city of Catania. It is a prototype of a cabled deep-sea multiparameter observatory and the first one operating with real-time data transmission in Europe since 2005. NEMO-SN1 is also the first-established node of the European Multidisciplinary Seafloor Observatory (EMSO), one of the incoming European large-scale research infrastructures included in the Roadmap of the European Strategy Forum on Research Infrastructures (ESFRI) since 2006. EMSO will specifically address long-term monitoring of environmental processes related to marine ecosystems, climate change, and geohazards. NEMO-SN1 has been deployed and developed over the last decade thanks to Italian funding and to the European Commission (EC) project European Seas Observatory NETwork—Network of Excellence (ESONET-NoE, 2007–2011) that funded the Listening to the Deep Ocean—Demonstration Mission (LIDO-DM) and a technological interoperability test (http://www.esonet-emso.org). NEMO-SN1 is performing geophysical and environmental long-term monitoring by acquiring seismological, geomagnetic, gravimetric, accelerometric, physico-oceanographic, hydroacoustic, and bioacoustic measurements. Scientific objectives include studying seismic signals, tsunami generation and warnings, its hydroacoustic precursors, and ambient noise characterization in terms of marine mammal sounds, environmental and anthropogenic sources. NEMO-SN1 is also an important test site for the construction of the Kilometre-Cube Underwater Neutrino Telescope (KM3NeT), another large-scale research infrastructure included in the ESFRI Roadmap based on a large volume neutrino telescope. The description of the observatory and its most recent implementations is presented. On June 9, 2012, NEMO-SN1 was successfully deployed and is working in real time.</skos:changeNote>

text: The BeiDou Navigation Satellite System will provide global coverage with positioning, navigation and timing services, including two kinds of service modes: an open service and an authorized service. The open service is provided free of charge location, velocity and timing, with positioning accuracy of 10 meters, velocity accuracy of 0.2 meters / second and timing accuracy of 10 nanoseconds. The authorized service provides a more secure position, velocity, timing, and communications services as well as a higher level of integrity.
In order to make BeiDou Navigation Satellite System work better for global service, strengthen compatibility and interoperability between BeiDou and other countries’satellite navigation systems,and promote satellite positioning, navigation and timing service application, China is willing to cooperate with other countries in developing satellite navigation industry.

    <skos:definition xml:lang="en">The BeiDou Navigation Satellite System will provide global coverage with positioning, navigation and timing services, including two kinds of service modes: an open service and an authorized service. The open service is provided free of charge location, velocity and timing, with positioning accuracy of 10 meters, velocity accuracy of 0.2 meters / second and timing accuracy of 10 nanoseconds. The authorized service provides a more secure position, velocity, timing, and communications services as well as a higher level of integrity.In order to make BeiDou Navigation Satellite System work better for global service, strengthen compatibility and interoperability between BeiDou and other countries’satellite navigation systems,and promote satellite positioning, navigation and timing service application, China is willing to cooperate with other countries in developing satellite navigation industry.</skos:definition>

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

The Joint Polar Satellite System (JPSS) is the restructured civilian portion of the National Polar-orbiting Operational Environmental Satellite System (NPOESS) that will make afternoon observations as it orbits Earth. The system includes the satellites and sensors supporting civil weather and climate measurements and a shared ground infrastructure with the Department of Defense weather satellite system.


NOAA is responsible for the JPSS program. NASA is the program’s procurement agent, and the agency’s 

Goddard Space Flight Center in Greenbelt, Md., is the lead for acquisition. Data and imagery obtained from JPSS will increase the timeliness, accuracy and cost-effectiveness of public warnings and forecasts of climate and weather events, reducing the potential loss of human life and property.

Polar-orbiting satellites observe Earth from space and collect and disseminate data on Earth’s weather, atmosphere, oceans, land, and near-space environment and are able to monitor the entire planet and provide data for long-range weather and climate forecasts.

Old Value=NOAA-20, which launched into space on November 18, 2017, is the first spacecraft of NOAA&apos;s next generation of polar-orbiting satellites. Capitalizing on the success of Suomi NPP, NOAA-20 features five similar instruments: (1) VIIRS, (2) CrIS, (3) ATMS, (4) OMPS-N, and (5) CERES-FM6. NOAA-20 has a design life of seven years and it will circle the Earth in the same orbit as Suomi NPP, although the two satellites will be separated in time and space by 50 minutes.

New Value=NOAA-20, which launched into space on November 18, 2017, is the first spacecraft of NOAA&apos;s next generation of polar-orbiting satellites. Capitalizing on the success of Suomi NPP, NOAA-20 features five similar instruments: (1) VIIRS, (2) CrIS, (3) ATMS, (4) OMPS-N, and (5) CERES-FM6. NOAA-20 has a design life of seven years and it will circle the Earth in the same orbit as Suomi NPP, although the two satellites will be separated in time and space by 50 minutes.

The Joint Polar Satellite System (JPSS) is the restructured civilian portion of the National Polar-orbiting Operational Environmental Satellite System (NPOESS) that will make afternoon observations as it orbits Earth. The system includes the satellites and sensors supporting civil weather and climate measurements and a shared ground infrastructure with the Department of Defense weather satellite system.


NOAA is responsible for the JPSS program. NASA is the program’s procurement agent, and the agency’s 

Goddard Space Flight Center in Greenbelt, Md., is the lead for acquisition. Data and imagery obtained from JPSS will increase the timeliness, accuracy and cost-effectiveness of public warnings and forecasts of climate and weather events, reducing the potential loss of human life and property.

Polar-orbiting satellites observe Earth from space and collect and disseminate data on Earth’s weather, atmosphere, oceans, land, and near-space environment and are able to monitor the entire planet and provide data for long-range weather and climate forecasts.

text: The SENTINEL-1 mission is the European Radar Observatory for the Copernicus joint initiative of the European Commission (EC) and the European Space Agency (ESA). Copernicus, previously known as GMES, is a European initiative for the implementation of information services dealing with environment and security. It is based on observation data received from Earth Observation satellites and ground-based information. The SENTINEL-1 mission includes C-band imaging operating in four exclusive imaging modes with different resolution (down to 5 m) and coverage (up to 400 km). It provides dual polarization capability, very short revisit times and rapid product delivery. For each observation, precise measurements of spacecraft position and attitude are available. Synthetic Aperture Radar (SAR) has the advantage of operating at wavelengths not impeded by cloud cover or a lack of illumination and can acquire data over a site during day or nighttime under all weather conditions. SENTINEL-1, with its C-SAR instrument, can offer reliable, repeated wide area monitoring. The mission is composed of a constellation of three satellites, SENTINEL-1A, SENTINEL-1B, and SENTINEL-1C, sharing the same orbital plane. SENTINEL-1 is designed to work in a pre-programmed, conflict-free operation mode, imaging all global landmasses, coastal zones and shipping routes at high resolution and covering the global ocean with vignettes. This ensures the reliability of service required by operational services and a consistent long term data archive built for applications based on long time series.

text: A type of offshore platform used for the extraction of petroleum or gas. These platforms are built on concrete and/or steel legs anchored directly onto the seabed, supporting a deck with space for drilling rigs, production facilities and crew quarters. Such platforms are, by virtue of their immobility, designed for very long-term use. Various types of structure are used, steel jacket, concrete caisson, floating steel and even floating concrete. Steel jackets are vertical sections made of tubular steel members, and are usually piled into the seabed. Concrete caisson structures, pioneered by the Condeep concept, often have in-built oil storage in tanks below the sea surface and these tanks were often used as a flotation capability, allowing them to be built close to shore (Norwegian fjords and Scottish firths are popular because they are sheltered and deep enough) and then floated to their final position where they are sunk to the seabed. Fixed platforms are economically feasible for installation in water depths up to about 500 feet (150 m); for deeper depths a floating production system, or a subsea pipeline to land or to shallower water depths for processing, would usually be considered.

text: Meteosat satellites are in geostationary orbit, so they orbit the Earth at the same rate that the Earth rotates about its axis. This enables continuous observations of around one-third of the Earth’s surface from their orbit 36,000km above the equator. Observations from geostationary orbit can save lives on Earth, as changes in weather and climate significantly impact not only our economy and infrastructure but also our lives. According to the World Meteorological Organization, there were more than 11 000 disasters attributed to weather, climate, and water-related hazards, which accounted for just over two million deaths and 3 trillion euros in losses between 1970 and 2019. Severe weather phenomena such as storms or even heavy fog can pose a significant threat to safety or business efficiency that require timely warnings to minimize their impact. To issue warnings and support decision makers, weather forecasters perform “nowcasting” to detect, in real time, rapidly developing situations of high impact weather, and predict their evolution a few hours ahead.  Nowcasting requires very frequent, high-quality observational data about the state of the atmosphere in real time - data that advanced geostationary weather satellites such as Meteosat can deliver continuously from their fixed position above the Earth’s surface. The Meteosat satellites are also able to deliver information on winds by observing the displacement of clouds and water vapor patterns, an essential input for numerical weather prediction models. These complement other observations made by polar-orbiting satellites such as Metop, which remain the primary source for global numerical weather prediction models.

    <skos:definition xml:lang="en">Meteosat satellites are in geostationary orbit, so they orbit the Earth at the same rate that the Earth rotates about its axis. This enables continuous observations of around one-third of the Earth’s surface from their orbit 36,000km above the equator. Observations from geostationary orbit can save lives on Earth, as changes in weather and climate significantly impact not only our economy and infrastructure but also our lives. According to the World Meteorological Organization, there were more than 11 000 disasters attributed to weather, climate, and water-related hazards, which accounted for just over two million deaths and 3 trillion euros in losses between 1970 and 2019. Severe weather phenomena such as storms or even heavy fog can pose a significant threat to safety or business efficiency that require timely warnings to minimize their impact. To issue warnings and support decision makers, weather forecasters perform “nowcasting” to detect, in real time, rapidly developing situations of high impact weather, and predict their evolution a few hours ahead.  Nowcasting requires very frequent, high-quality observational data about the state of the atmosphere in real time - data that advanced geostationary weather satellites such as Meteosat can deliver continuously from their fixed position above the Earth’s surface. The Meteosat satellites are also able to deliver information on winds by observing the displacement of clouds and water vapor patterns, an essential input for numerical weather prediction models. These complement other observations made by polar-orbiting satellites such as Metop, which remain the primary source for global numerical weather prediction models.</skos:definition>

New Value=Satellites that are specifically designed to observe Earth from orbit, similar to spy satellites but intended for non-military uses such as environmental monitoring, meteorology, map making etc.The most common type are Earth imaging satellites, that take satellite images, analogous to aerial photographs; some EO satellites may perform remote sensing without forming pictures, such as in GNSS radio occultation.</skos:changeNote>

text: QuickBird was a high-resolution commercial Earth observation satellite owned by DigitalGlobe, launched in 2001 and reentered after orbit decay in 2015. QuickBird used Ball Aerospace&apos;s Global Imaging System 2000 (BGIS 2000). The satellite collected panchromatic (black and white) imagery at 61 centimeter resolution and multispectral imagery at 2.44- (at 450 km) to 1.63-meter (at 300 km) resolution, as orbit altitude is lowered during the end of mission life.

text: GLONASS or &quot;Global Navigation Satellite System&quot;, is a space-based satellite navigation system operating in the radionavigation-satellite service. It provides an alternative to GPS and is the second navigational system in operation with global coverage and of comparable precision.

Manufacturers of GPS devices say that adding GLONASS made more satellites available to them, meaning positions can be fixed more quickly and accurately, especially in built-up areas where the view to some GPS satellites is obscured by buildings. Smartphones generally tend to use the same chipsets and the versions used since 2015 receive GLONASS signals and positioning information along with GPS. Since 2012, GLONASS was the second most used positioning system in mobile phones after GPS. The system has the advantage that smartphone users receive a more accurate reception identifying location to within 2 meters.

Copernicus, previously known as GMES, is a European initiative for the implementation of information services dealing with environment and security. It is based on observation data received from Earth Observation satellites and ground-based information. The SENTINEL-1 mission includes C-band imaging operating in four exclusive imaging modes with different resolution (down to 5 m) and coverage (up to 400 km). It provides dual polarization capability, very short revisit times and rapid product delivery. For each observation, precise measurements of spacecraft position and attitude are available. Synthetic Aperture Radar (SAR) has the advantage of operating at wavelengths not impeded by cloud cover or a lack of illumination and can acquire data over a site during day or nighttime under all weather conditions. SENTINEL-1, with its C-SAR instrument, can offer reliable, repeated wide area monitoring. The mission is composed of a constellation of three satellites, SENTINEL-1A, SENTINEL-1B, and SENTINEL-1C, sharing the same orbital plane. SENTINEL-1 is designed to work in a pre-programmed, conflict-free operation mode, imaging all global landmasses, coastal zones and shipping routes at high resolution and covering the global ocean with vignettes. This ensures the reliability of service required by operational services and a consistent long term data archive built for applications based on long time series.</skos:changeNote>

The NPOESS Preparatory Project (NPP) spacecraft lifted off aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2 at Vandenberg Air Force Base in California on Oct. 28, 2011 at 5:48 a.m. EDT.

The NPP spacecraft will build on more than four decades Earth observation to help us better understand our climate.

The National Polar-Orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) is a joint mission involving the National Aeronautics and Space Administration&apos;s (NASA) and the NPOESS Integrated Program Office (IPO).  

The NPP mission collects and distributes remotely-sensed land, ocean, and atmospheric data to the meteorological and global climate change communities as the responsibility for these measurements transitions from existing Earth-observing missions such as Aqua, Terra and Aura, to the NPOESS. It will provide atmospheric and sea surface temperatures, humidity sounding, land and ocean biological productivity, and cloud and aerosol properties.

For the IPO, NPP provides risk reduction with an opportunity to demonstrate and validate new instruments and processing algorithms, as well as to demonstrate and validate aspects of the NPOESS command, control, communications and ground processing capabilities prior to the launch of the first NPOESS spacecraft.

It will provide atmospheric and sea surface temperatures, humidity sounding, land and ocean biological productivity, and cloud and aerosol properties.For the IPO, NPP provides risk reduction with an opportunity to demonstrate and validate new instruments and processing algorithms, as well as to demonstrate and validate aspects of the NPOESS command, control, communications and ground processing capabilities prior to the launch of the first NPOESS spacecraft.More Information: https://www.jpss.noaa.govGroup: Platform_Details   Entry_ID: SUOMI-NPP   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: Joint Polar Satellite System (JPSS)      Short_Name: SUOMI-NPP      Long_Name: Suomi National Polar-orbiting Partnership   End_Group   Group: Platform_Associated_Instruments      Short_Name: CRIMSS      Short_Name: ATMS      Short_Name: CRIS-NPOESS      Short_Name: OMPS      Short_Name: VIIRS      Short_Name: CERES-FM5   End_Group   Group: Orbit      Repeat_Cycle: 16-day      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2009-02-27   Online_Resource: https://www.jpss.noaa.gov/   Online_Resource: https://www.nasa.gov/mission_pages/NPP/main/index.html   Group: Platform_Logistics      Launch_Date: 2011-10-28      Launch_Site: Vandenberg Air Force Base, USA      Primary_Sponsor: USA/NASA      Primary_Sponsor: USA/NOAA   End_GroupEnd_Group</skos:definition>

text: A series of uncrewed Soviet and then Russian satellites launched from the early 1960s to the present day. As of 2020 there were 2,544 satellites in the series. The first was launched on March 16, 1962. Kosmos satellites were used for a wide variety of purposes, including scientific research, navigation, and military reconnaissance. In the Soviet years, failures of probes in other programs were given a Kosmos number. Kosmos 26 and 49 (both launched in 1964), for example, were equipped to measure Earth’s magnetic field. Others were employed to study certain technical aspects of spaceflight as well as physical phenomena in Earth’s upper atmosphere and in deep space. A number of them—such as Kosmos 597, 600, and 602—were apparently used to collect intelligence on the Yom Kippur War (the fourth Arab-Israeli war) in October 1973. Some Kosmos spacecraft had the ability to intercept satellites launched by other nations. Other Kosmos satellites have proved much more notable for how their missions ended. Kosmos 954, a Soviet navy satellite powered by a nuclear reactor, crashed in the Northwest Territories of Canada on January 24, 1978, scattering radioactive debris. The first collision that destroyed an operational satellite happened on February 10, 2009, when Kosmos 2251, an inactive Russian military communications satellite, collided with Iridium 33, a communications satellite owned by the American company Motorola, about 760 km (470 miles) above northern Siberia, shattering both satellites.

text: The Global Data Assimilation System (GDAS) is the system used by the Global Forecast System (GFS) model to place observations into a gridded model space for the purpose of starting, or initializing, weather forecasts with observed data. GDAS adds the following types of observations to a gridded, 3-D, model space: surface observations, balloon data, wind profiler data, aircraft reports, buoy observations, radar observations, and satellite observations. GDAS data are available as both input observations to GDAS and gridded output fields from GDAS. Gridded GDAS output data can be used to start the GFS model. Due to the diverse nature of the assimilated data types, input data are available in a variety of data formats, primarily Binary Universal Form for the Representation of meteorological data (BUFR) and Institute of Electrical and Electronics Engineers (IEEE) binary. The GDAS output is World Meteorological Organization (WMO) Gridded Binary (GRIB).

    <skos:definition xml:lang="en">[Text Source: NASA/NSSDC, http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=2002-021A ]Spot 5 is a French (CNES), Earth-imaging, three tonne satellite that was launched by an Ariane 42P rocket from Kourou at 00:31:00 UT on 4 May 2002. Its planar and stereoscopic relief images at about three meter resolution will be marketed for civilian and military uses, for cartographic and vegetation analyses. Panchromatic (at 2.5 m resolution) as well as multispectral images (at 10 m resolution) could be obtained. The position of the satellite, and hence the location of the images could be determined at 15 m accuracy by means of the DORIS position determination instrument.

text: The Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) provides data beginning in 1980. It was introduced to replace the original MERRA dataset because of the advances made in the assimilation system that enable assimilation of modern hyperspectral radiance and microwave observations, along with GPS-Radio Occultation datasets. It also uses NASA&apos;s ozone profile observations that began in late 2004. Additional advances in both the GEOS model and the GSI assimilation system are included in MERRA-2. Spatial resolution remains about the same (about 50 km in the latitudinal direction) as in MERRA.

Along with the enhancements in the meteorological assimilation, MERRA-2 takes some significant steps towards GMAO’s target of an Earth System reanalysis. MERRA-2 is the first long-term global reanalysis to assimilate space-based observations of aerosols and represent their interactions with other physical processes in the climate system.

    <skos:definition xml:lang="en">The Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) provides data beginning in 1980. It was introduced to replace the original MERRA dataset because of the advances made in the assimilation system that enable assimilation of modern hyperspectral radiance and microwave observations, along with GPS-Radio Occultation datasets. It also uses NASA&apos;s ozone profile observations that began in late 2004. Additional advances in both the GEOS model and the GSI assimilation system are included in MERRA-2. Spatial resolution remains about the same (about 50 km in the latitudinal direction) as in MERRA.Along with the enhancements in the meteorological assimilation, MERRA-2 takes some significant steps towards GMAO’s target of an Earth System reanalysis. MERRA-2 is the first long-term global reanalysis to assimilate space-based observations of aerosols and represent their interactions with other physical processes in the climate system. MERRA-2 includes a representation of ice sheets over (say) Greenland and Antarctica.</skos:definition>

Old Value=Crewed or uncrewed travel between stars and planets, usually within a single planetary system. In practice, spaceflights of this type are confined to travel between the planets of the Solar System. Uncrewed space probes have flown to all the observed planets in the Solar System as well as to dwarf planets Pluto and Ceres, and several asteroids. Orbiters and landers return more information than fly-by missions. Crewed flights have landed on the Moon and have been planned, from time to time, for Mars and Venus. While many scientists appreciate the knowledge value that uncrewed flights provide, the value of crewed missions is more controversial. Science fiction writers propose a number of benefits, including the mining of asteroids, access to solar power, and room for colonization in the event of an Earth catastrophe.

text: Pléiades Neo is a constellation of four identical satellites at 30cm native resolution. The constellation is 100% funded by Airbus group, it was manufactured by Space Systems and operated by Intelligence.
The satellites are positioned at 620km altitude, operated as a genuine constellation on the same orbit and phased at 90° from each other and hence offer an intraday revisit capacity anywhere on Earth (at least twice a day) and an acquisition capacity of 2M km² per day (with four satellites). The location accuracy is 3.5m CE90 (native). The satellites are equipped with two new spectral bands: red-edge for crop and vegetation monitoring, and deep blue for bathymetry applications. The satellites are also equipped by Laser Communication Terminals through the SpaceDataHighway (EDRS) allowing reactive tasking.

The constellation is 100% funded by Airbus group, it was manufactured by Space Systems and operated by Intelligence.The satellites are positioned at 620km altitude, operated as a genuine constellation on the same orbit and phased at 90° from each other and hence offer an intraday revisit capacity anywhere on Earth (at least twice a day) and an acquisition capacity of 2M km² per day (with four satellites). The location accuracy is 3.5m CE90 (native). The satellites are equipped with two new spectral bands: red-edge for crop and vegetation monitoring, and deep blue for bathymetry applications. The satellites are also equipped by Laser Communication Terminals through the SpaceDataHighway (EDRS) allowing reactive tasking.</skos:definition>

    <skos:definition xml:lang="en">The  Echo  2  spacecraft  was  a  41-m  balloon of aluminum foil-mylar  laminate.   Echo  2 was designed as a rigidized passive communications  spacecraft   for  testing  propagation,  tracking,  and  communication  techniques.   Instrumentation  included a beacon telemetry system that  provided  a  tracking  signal,  monitored  spacecraft skin temperature  between  -120  deg C and +16 deg C, and measured the internal pressure  of  the  spacecraft  between 5E-5 mm of mercury and 0.5 mm of mercury,  especially  during  the  initial inflation stages.  This system, which  consisted  of  two beacon assemblies, used solar cell panels for power  and  had a minimum power output of 45 mW at 136.17 MHz and 136.02 MHz.  In  addition  to fulfilling its communications mission, the spacecraft  was  used for global geometric geodesy.  The spacecraft re-entered the  atmosphere on June 7, 1969.

The Ice, Cloud, and Land Elevation Satellite-2, or ICESat-2, will measure the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second. Slated for launch in 2018, ICESat-2 will carry a photon-counting laser altimeter that will allow scientists to measure the elevation of ice sheets, glaciers, sea ice and more - all in unprecedented detail.

Our planet&apos;s frozen and icy areas, called the cryosphere, are a key focus of NASA&apos;s Earth science research. ICESat-2 will help scientists investigate why, and how much, our cryosphere is changing in a warming climate. The satellite will also measure heights across Earth&apos;s temperate and tropical regions, and take stock of the vegetation in forests worldwide.

ICESat-2 will provide scientists with height measurements that create a global portrait of Earth’s 3rd dimension, 
gathering data that can precisely track changes of terrain including glaciers, sea ice, forests and more.

While many of ICESat-2’s discoveries are yet to be imagined, the satellite mission has four science objectives:

Measure melting ice sheets and investigate how this effects sea level rise,
Measure and investigate changes in the mass of ice sheets and glaciers,
Estimate and study sea ice thickness,
Measure the height of vegetation in forests and other ecosystems worldwide.

ICESat (Ice, Cloud,and land Elevation Satellite) is the benchmark Earth Observing System mission for measuring ice sheet mass balance, cloud and aerosol heights, as well as land topography and vegetation characteristics. The ICESat mission is providing multi-year elevation data needed to determine ice sheet mass balance as well as cloud property information, especially for stratospheric clouds which are common over polar areas. It will also provide topography and vegetation data around the globe, in addition to the polar-specific coverage over the Greenland and Antarctic ice sheets.

As envisioned by the Decadal Study, the ICESat-2 mission is to deploy an ICESat follow-on satellite to continue the assessment of polar ice changes. ICESat-2 is also expected to measure vegetation canopy heights, allowing estimates of biomass and carbon in above ground vegetation in conjunction with related missions, and allow measurements of solid earth properties. ICESat-2 is expected to launch in 2016.

text: A low-cost air pollution monitor is a device that uses one or more than one sensor and other components to detect, monitor, and report on specific air pollutants like particulate matter (PM) or carbon dioxide and/or environmental factors such as temperature and humidity. Low-cost air pollution monitors can provide a way to get information about specific pollutants that may be in indoor air. Depending on the sensor(s) used, these monitors may detect one or a combination of pollutants or indoor environmental factors. Low-cost air pollution monitors may also be referred to as air sensors, air quality sensors, air quality monitors, air pollutant monitors, or low-cost air sensors. Some of these monitors have a single sensor that detects or measures a single air pollutant or environmental factor. Others may contain multiple sensors designed to detect several, or a combination of, indoor pollutants or environmental factors.

    <skos:definition xml:lang="en">The Nimbus 7 research-and-development satellite served as astabilized, earth-oriented platform for the testing of advancedsystems for sensing and collecting data in the pollution,oceanographic and meteorological disciplines.  The polar-orbitingspacecraft consisted of three major structures: (1) a hollowtorus-shaped sensor mount, (2) solar paddles, and (3) a controlhousing unit that was connected to the sensor mount by a tripod trussstructure.  Configured somewhat like an ocean buoy, Nimbus-7 wasnearly 3.04 m tall, 1.52 m in diameter at the base, and about 3.96 mwide with solar paddles extended.  The sensor mount that formed thesatellite base housed the electronics equipment and battery modules.The lower surface of the torus provided mounting space for sensors andantennas.  A box-beam structure mounted within the center of the torusprovided support for the larger sensor experiments.  Mounted on thecontrol housing unit, which was located on top of the spacecraft, weresun sensors, horizon scanners, and a command antenna.  The spacecraftspin axis was pointed at the earth.  An advanced attitude-controlsystem permitted the spacecraft&apos;s orientation to be controlled towithin plus or minus 1 deg in all three axes (pitch, roll, and yaw).Eight experiments were selected: (1) Limb Infrared Monitoring of theStratosphere (LIMS), (2) Stratospheric And Mesopheric Sounder (SAMS),(3) Coastal-Zone Color Scanner (CZCS), (4) Stratospheric AerosolMeasurement II (SAM II), (5) Earth Radiation Budget (ERB), (6)Scanning Multichannel Microwave Radiometer (SMMR), (7) SolarBackscatter UV and Total Ozone Mapping Spectrometer (SBUV/TOMS), and(8) Temperature-Humidity Infrared Radiometer (THIR).  These sensorswere capable of observing several parameters at and below themesospheric levels.  The Nimbus-7 spacecraft was turned off in 1994after 16 years of service.Group: Platform_Details   Entry_ID: NIMBUS-7   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: NIMBUS      Short_Name: NIMBUS-7   End_Group   Group: Synonymous_Platform_Names      Short_Name: Nimbus-G   End_Group   Group: Platform_Associated_Instruments      Short_Name: CZCS      Short_Name: TOMS      Short_Name: SBUV      Short_Name: LIMS      Short_Name: THIR      Short_Name: SAMS      Short_Name: SMMR      Short_Name: ERB   End_Group   Group: Orbit      Orbit_Altitude: 955 km      Orbit_Inclination: 99.1 degree      Equator_Crossing: 12:00 PM for ascending and 12:00 AM for descending      Period: 104.15 min.

    <skos:definition xml:lang="en">The fourth in the IRS series, IRS - 1C was launched from Baikanur cosmodrome, Kazakhstan on May 19, 1995. It operates in a near polar, sun- synchronous orbit at an altitude of 817km. Its local equatorial crossing time is 10:30 A.M in the descending node. The satellite payload consists of three sensors, namely Panchromatic camera (PAN), Linear Imaging and Self-Scanning Sensor (LISS - III) and Wide Field Sensor (WiFS).The PAN camera provides data with a spatial resolution of 5.8m and a ground swath of 70 km at nadir view. This camera can be steered up to +/- 26 degrees, which can be used to acquire stereo pairs and this also improves the revisit capability to 5 days.LISS - III camera provides multi-spectral data in 4 bands. The spatial resolution for visible (two bands) and near infrared (one band) is 23.5m with a ground swath of 141 km. The fourth band (short wave infrared band) has a spatial resolution of 70.5m with a ground swath of 148 km. The repetivity of LISS - III is 24 days.WiFS camera collects data in two spectral bands with a spatial resolution of 188m and a ground swath of 810 km. By virtue of its wide swath there is huge side lap between adjacent paths. A repetivity of 3 days can be achieved by suitably combining paths.The satellite is equipped with an On Board Tape Recorder (OBTR) with a capacity of 62 Gb, for collecting data outside the visibility region of any ground station. The OBTR was capable of storing data collected for 24 minutes. The OBTR was functional during 1995-1998.

text: Following the successful demonstration flights of Bhaskara-1 and Bhaskara-2 - experimental Earth observation satellites developed and built by ISRO (Indian Space Research Organization) - and launched in 1979 and 1981, respectively, India began the development of an indigenous IRS (Indian Remote Sensing Satellite) program. India realized quite early that sustaining its space program in the long run would depend on indigenous technological capabilities (in particular, US export restrictions made this clear). Keeping this in mind, besides building satellites, India embarked as well on satellite launch vehicle development in the early 1970s. As a consequence, India has two very capable launch systems at the start of the 21st century, namely PSLV (Polar Satellite Launch Vehicle) and GSLV (Geosynchronous Satellite Launch Vehicle). 1)

IRS is the integrated LEO (Low Earth Orbit) element of India&apos;s NNRMS (National Natural Resources Management System) with the objective to provide a long-term spaceborne operational capability to India for the observation and management of the country&apos;s natural resources (applications in agriculture, hydrology, geology, drought and flood monitoring, marine studies, snow studies, and land use). The intend of the program is to create an environment of new perspectives for the Indian research community as a whole, to stimulate the development of new technologies and applications, and to utilize the Earth resources in more meaningful ways.

text: Spatial, temporal, and size distributions of mineral dust with sizes of less than 10 µm radius were calculated with a global dust model (Tegen and Fung 1994, see References below) based on the GISS three-dimensional atmospheric tracer transport model (Russell and Lerner 1981). The total dust load as well as the part that is deflated from disturbed soils was calculated (Tegen and Fung 1995). The contribution from disturbed soils should be taken into account in climate change studies (Tegen et al. 1996). As dust particle size information is important for calculations of the dust radiative effect, we provide concentrations for 8 particle size classes with effective radii between 0.1 µm and 10 µm which were transported independently in the model.

    <skos:definition xml:lang="en">[Source: National Space Science Data Center,  http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1991-082A ] DMSP 5D-2/F11 is one of a series of meteorological satellites developed and operated by the Air Force under the Defense Meteorological Satellite Program (DMSP). This program, previously known as DAPP (Data Acquisition and Processing Program), was classified until March 1973. The objective of this program is to provide global visual and infrared cloudcover data and specialized environmental data to support Department of Defense operational weather analysis and forecasting requirements. Operationally, the program consists of two satellites in sun-synchronous polar orbits, with the ascending node of one satellite in early morning and the other at local noon. The 6.4-m-long spacecraft is separated into four sections: (1) a precision mounting platform for sensors and equipment requiring precise alignment; (2) an equipment support module containing the electronics, reaction wheels, and some meteorological sensors; (3) a reaction control equipment support structure containing the third-stage rocket motor and supporting the ascent phase reaction control equipment; and (4) a 9.29-sq-m solar cell panel. The spacecraft stabilization is controlled by a combination flywheel and magnetic control coil system so that sensors are maintained in the desired earth-looking mode. One feature is the precision-pointing accuracy of the primary imager to 0.01 deg provided by a star sensor and an updated ephemeris navigation system. This allows automatic geographical mapping of the digital imagery to the nearest picture element. The operational linescan system is the primary data acquisition system that provides real-time or stored, multi-orbit, day-and-night, visual and infrared imagery of clouds. A supplementary sensor package contains five special sensors: (1) a microwave temperature sounder, (2) an X-ray spectrometer, (3) an ionospheric/scintillation monitor, (4) a precipitating electron/ion spectrometer, and (5) a microwave imager. Either recorded or real-time data are transmitted to ground-receiving sites by two redundant S-band transmitters. Recorded data are read out to tracking sites located at Fairchild AFB, Washington, and at Loring AFB, Maine, and relayed by SATCOM to Air Force Global Weather Central, Offutt AFB, Nebraska. Real-time data are read out at mobile tactical sites located around the world. Additional information concerning this satellite can be found in the report by D. A. Nichols, &apos;The Defense Meteorological Satellite Program,&apos; Optical Engineering, v. 14, n. 4, p. 273, July-August 1975.Group: Platform_Details   Entry_ID: DMSP 5D-2/F11   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: DMSP (Defense Meteorological Satellite Program)      Short_Name: DMSP 5D-2/F11      Long_Name: Defense Meteorological Satellite Program-F11   End_Group   Group: Synonymous_Platform_Names      Short_Name: DMSP-F11      Short_Name: USA 73      Short_Name: 21798   End_Group   Group: Platform_Associated_Instruments      Short_Name: OLS      Short_Name: SSM/I      Short_Name: SSJ/4      Short_Name: SSI/ES      Short_Name: SSM/T      Short_Name: SSB/X      Short_Name: SSM/T-2   End_Group   Group: Orbit      Orbit_Inclination: 98.9°      Period: 101.9 minutes      Perigee: 846.0 km      Apogee: 870.0 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Online_Resource: http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1991-082A   Online_Resource: http://www.ngdc.noaa.gov/dmsp/index.html   Online_Resource: http://heasarc.gsfc.nasa.gov/docs/heasarc/missions/dmsp.html   Group: Platform_Logistics      Launch_Date: 1991-11-28      Launch_Site: Vandenberg Air Force Base, USA      Primary_Sponsor: Department of Defense-Department of the Air Force (United States)   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">While Convair (based in San Diego like the Classic Airliner Page) was quite successful with its piston powered CV-240/340/440 series of twins, it recognized as early as 1950 that turboprop engines offered some clear advantages over the &apos;round engines&apos;.  Instead of building a new plane, Convair decided that those very Convair-Liners could be re-engined instead.  An experimental installation of Allison T56 engines into a CV-240 in 1950 was quite successful, but the first commercial conversion did not take place until 1954, and then with British Napier Elands.

Old Value=Landsat 4 is the fourth satellite of the Landsat program. It was launched on
July 16th, 1982, with the primary goal of providing a global archive of
satellite photos. Although the Landsat Program is managed by NASA, data from
Landsat 4 was collected and distributed by the USGS. Landsat 4 is no longer in
operation, due to technical failure. It finally ceased transmission in 1993,
far beyond its designed life expectancy of five years. The satellite orbit
continues to be maintained by NASA.

Landsat 4 had a maximum transmission bandwidth of 85 Mbit/s, and carried an
updated Multi-Spectral Scanner used on previous Landsats, and a Thematic
Mapper. It had a maximum 30 m resolution. Shortly after launch, the satellite
lost half of its solar power, prompting fears the satellite would fail sooner
than expected. This prompted the early launch of Landsat 5, a satellite
identical in specification to Landsat 4.

Old Value=AD-A Atmospheric Dynamics A (Explorer 19)

Explorer 19 was the second in a series of 3.66-m inflatable spheres placed into orbit to determine atmospheric densities. Explorer 19 was launched while Explorer 9, the first satellite in the series, was still active, so that densities in two different portions of the atmosphere were sampled simultaneously. The satellite consisted of alternating layers of aluminum foil and plastic film. Uniformly distributed over the aluminum outer surface were 5.1-cm dots of white paint for thermal control. A 136.620-MHz tracking beacon, which was powered by four solar cells and was mounted on the spacecraft skin, used the electrically separated hemispheres of the balloon as an antenna. The spacecraft was successfully orbited, but its apogee was lower than planned. The beacon did not have sufficient power to be received by ground tracking stations, making it necessary to rely solely on the SAO Baker-Nunn camera network for tracking.

text: Objectives: Continued development of the experimental television techniques and infrared equipment leading to a worldwide meteorological information system. To obtain infrared measurements of the solar energy absorbed, reflected and emitted by the Earth.

Description: The spacecraft was 42 inches in diameter, 19 inches high and weighed 285 pounds. The craft was made of aluminum alloy and stainless steel then covered by 9260 solar cells. The solar cells served to charge the nickel-cadmium batteries. Three major changes were made from the previous TIROS models. Two wide-angle television cameras were housed in the craft in place of one high-resolution and one low-resolution camera.

A new infrared experiment and improved remote control programmers were also new additions. This craft contained an electronic clock to control the operations of the infrared horizon sensor as well as the magnetic orientation system. A magnetic tape recorder was still provided for each camera to store photographs while the satellite was out of range of the ground station network. One scanning and two non-scanning radiometers were also on board.

The antennas were of the same configuration as both previous TIROS models. Although one of the cameras failed 12 days into the mission, photograph quality from the other camera was excellent and many tropical storms during the 1961 hurricane season were photographed. TIROS-3 was also credited with the discovery of Hurricane Esther.

ALOS is a Japanese Earth-Observation satellite, developed by JAXA. The
objective of the mission is to provide the user community with data of
sufficient resolution to be able to generate 1:25,000 scale maps. ALOS
mission objectives as set by JAXA are to:

- Develop digital elevation models (DEMs) and related geographic data
products
- Perform regional observation for &apos;sustainable development&apos;
(harmonization between Earth environment and development)
- Conduct disaster monitoring around the world
- Survey natural resources
- Develop sensor and satellite technology for future Earth-observing
satellites

The mission includes optical and an active L-band microwave sensor
payload whose high-resolution data may be used for environmental and
hazard monitoring. ESA will provide the European/African node for data
distribution.

Old Value=The IRIS Global Seismographic Network (GSN) is one of the four
major components of the IRIS Consortium. The goal of the GSN is
to deploy 128 permanent seismic recording stations uniformly
over the earth&apos;s surface.

As of 2001 the GSN was made up of over 120 stations with
affiliations to IRIS USGS, IRIS IDA, GEOFON, Pacific21, NCDSN,
MedNet, BGR, BFO, USNSN, BDSN and several other national and
international networks. Thirteen new stations are planned for
completion in 2001/2002.

The IRIS GSN stations continuously record seismic data from very
broad band seismometers at 20 samples per second. It is also the
goal of the GSN to record data with a dynamic range of 140 db
(24 bit digitizers). Nearly all of the IRIS GSN stations meet
this goal.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

    <skos:definition xml:lang="en">WIND was launched on November 1, 1994 and is the first of two NASA spacecraft in the Global Geospace Science initiative and part of the ISTP Project. WIND was positioned in a sunward, multiple double-lunar swingby orbit with a maximum apogee of 250Re during the first two years of operation. This was followed by a halo orbit at the Earth-Sun L1 point.The science objectives of the WIND mission are:- Provide conplete plasma, energetic particle, and magnetic field input formagnetospheric and ionospheric studies.- Determine the magnetospheric output to interplanetary space in theup-stream region- Investigate basic plasma processes occuring in the near-Earth solar wind- Provide baseline ecliptic plane observations to be used in heliosphericlatitudes from ULYSSES. WIND carries the following instruments:Radio and Plasma Wave experiment  (WAVES)Energetic Particle Acceleration, Composition, and Transport (EPACT)Solar Wind Experiment (SWE)Solar Wind and Suprathermal Ion Composition Studies (SWICS/MASS/STICS)Magnetic Fields Investigation (MFI)3-D Plasma and Energetic Particle Analyzer  (3DP)Transient Gamma-Ray Spectrometer (TGRS)Gamma Ray Burst Studies (KONUS)For more information, see:http://pwg.gsfc.nasa.gov/wind.shtmlandhttp://ssed.gsfc.nasa.gov/waves/Group: Platform_Details   Entry_ID: WIND   Group: Platform_Identification      Platform_Category: Solar/Space Observation Satellites      Short_Name: WIND   End_Group   Group: Synonymous_Platform_Names      Short_Name: GGS/Wind      Short_Name: ISTP/Wind      Short_Name: Wind/GGS      Short_Name: Wind/ISTP      Short_Name: 23333      Short_Name: 1994-071A   End_Group   Group: Platform_Associated_Instruments      Short_Name: SWIMS      Short_Name: KONUS      Short_Name: TGRS      Short_Name: 3DP      Short_Name: MFI      Short_Name: SMS      Short_Name: SWE      Short_Name: EPACT      Short_Name: WAVES   End_Group   Group: Orbit      Perigee: 235 ER      Apogee: 265 ER      Orbit_Type: LPO &gt; L1 &gt; Lissajous Orbit &gt; Halo Orbit   End_Group   Online_Resource: http://ssed.gsfc.nasa.gov/waves/   Sample_Image: http://nssdc.gsfc.nasa.gov/image/spacecraft/wind.jpg   Group: Platform_Logistics      Launch_Date: 1994-11-01      Launch_Site: Cape Canaveral/Kennedy Space Center, USA      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

text: The H2020 CAPTOR project deployed three testbeds in Spain, Italy and Austria with low-cost sensors for the measurement of tropospheric ozone (O3). The aim of the H2020 CAPTOR project was to raise public awareness in a project focused on citizen science. Each testbed was supported by an NGO in charge of deciding how to raise citizen awareness according to the needs of each country. The data presented in this document correspond to the raw data captured by the sensor nodes in the Spanish testbed using SGX Sensortech MICS 2614 metal-oxide sensors. The Spanish testbed consisted of the deployment of twenty-five nodes. Each sensor node included four SGX Sensortech MICS 2614 ozone sensors, one temperature sensor and one relative humidity sensor. Each node underwent a calibration process by co-locating the node at an EU reference air quality monitoring station, followed by a deployment in a sub-urban or rural area in Catalonia, Spain. All nodes spent two to three weeks co-located at a reference station in Barcelona, Spain (urban area), followed by two to three weeks co-located at three sub-urban reference stations near the final deployment site. The nodes were then deployed in volunteers&apos; homes for about two months and, finally, the nodes were co-located again at the sub-urban reference stations for two weeks for final calibration and assessment of potential drifts. All data presented in this paper are raw data taken by the sensors that can be used for scientific purposes such as calibration studies using machine learning algorithms, or once the concentration values of the nodes are obtained, they can be used to create tropospheric ozone pollution maps with heterogeneous data sources (reference stations and low-cost sensors).

Previous performance evaluations have typically studied a limited number of PurpleAir sensors in small geographic areas or laboratory environments. While useful for determining sensor behavior and data normalization for these geographic areas, little work has been done to understand the broad applicability of these results outside these regions and conditions. Here, PurpleAir sensors operated by air quality monitoring agencies are evaluated in comparison to collocated ambient air quality regulatory instruments.

    <skos:definition xml:lang="en">Alouette-2 was a small space based ionospheric observatory instrumentedwith a sweep-frequency ionospheric sounder (radio transmitter), a VLF radioreceiver, an energetic particle detector experiment, a cosmic radio noiseexperiment, and an electrostatic plasma probe.EXTERIOR ANTENNAS:  The spacecraft used two long dipole antennas(73 meter and 22.8 meter, respectively) for the sounder, VLF, and radiocosmic noise experiments.SPACECRAFT ROTATION (SPIN):   The satellite was spin-stabilized atabout 2.25 rpm after antenna deployment.  End plates on the 73 meterantenna corrected the rapid despin that had occurred on the predecessorspacecraft, Alouette 1, and which was believed to result from thermaldistortion of the antenna and from radiation pressure.DATA ACQUISITION:  There was no onboard tape recorder, so that datawere available to the ground receiving station only when the spacecraftwas in direct line of sight of telemetry stations.  Telemetry stationswere located  so that primary data coverage was near the 80 degreesWest meridan plus areas near Hawaii, Singapore, Australia, England,India, Norway and Central Africa.  Initially data were recorded about8 hours per day.  Degradation of the power supply system had, by June1975, reduced the operating time to about 1/2 hour per day.  Routineoperations were terminated in July 1975.  The spacecraft was alsosuccessfully reactivated on November 28 and 29, 1975, in order toobtain data on its 10th anniversary.Group: Platform_Details   Entry_ID: ALOUETTE-2   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: ALOUETTE      Short_Name: ALOUETTE-2   End_Group   Group: Synonymous_Platform_Names      Short_Name: ALOUETTE-B      Short_Name: 01804   End_Group   Group: Platform_Associated_Instruments      Short_Name: STEP FREQUENCY RADIOMETERS      Short_Name: ELECTROSTATIC ANALYZERS   End_Group   Creation_Date: 2007-08-22   Online_Resource: http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1965-098A   Group: Platform_Logistics      Launch_Date: 1965-11-29      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

text: Quantifying Fossil Fuel Carbon Dioxide Emissions from Space: Fossil Fuel Data Assimilation System and Global Urban Emissions
Gurney, K. R.; Song, Y.; Asefi-Najafabady, S.; Rayner, P. J.
Abstract
The Fossil Fuel Data Assimilation System (FFDAS) quantifies fossil fuel carbon dioxide (CO2) emissions for the planet at a scale of 10 km hourly for the time period 1997-2012. FFDAS is based on the Kaya identity constrained by multiple ground and space-based observations. Among these are the DMSP nightlights, Landscan population, and the Ventus power plant database. We have recently downscaled the FFDAS version 2.0 to 1 km x 1 km resolution using nighlights. The finer spatial resolution allows for the examination of urban emissions across the planet. We take two approaches to examination of urban FFCO2 emissions. The first, utilizes named administrative boundaries combined with manual GIS identification (supported by LandSat and ISA) to identify the top emitting urban areas of the planet. We also utilize an urban land mask, without governmental boundary identification, to analyze all urban area by country across the planet. We perform multiple regression to identify key drivers and patterns. The results demonstrate the change in urban emissions during the last decade and assess the question of whether urban areas exhibit scaling properties vis a vis FFCO2 emissions.

    <skos:definition xml:lang="en">- Spacecraft Brief Description -ISIS 1 was an ionospheric observatory instrumented with sweep- andfixed-frequency ionosondes, a VLF receiver, energetic and soft particledetectors, an ion mass spectrometer, an electrostatic probe, an electrostaticanalyzer, a beacon transmitter, and a cosmic noise experiment. The sounder usedtwo dipole antennas (73 and 18.7 m long). The satellite was spin-stabilized atabout 2.9 rpm after antenna deployment. Some control was exercised over thespin rate and attitude by using magnetically induced torques to change the spinrate and to precess the spin axis. A tape recorder with 1-h capacity wasincluded on the satellite. The satellite could be programmed to take recordedobservations for four different time periods for each full recording period.The recorder data were dumped only at Ottawa. For non-tape-recordedobservations, data for the satellite and subsatellite regions could be acquiredand telemetered when the spacecraft was in the line of sight of telemetrystations. The selected telemetry stations were in areas that provided primarydata coverage near the 80-deg-W meridian and in areas near Hawaii, Singapore,Australia, England, Norway, India, Japan, Antarctica, New Zealand, and CentralAfrica. NASA support of the ISIS project was terminated on October 1, 1979. Asignificant amount of experimental data, however, was acquired after this dateby the Canadian project team. ISIS 1 operations were terminated in Canada onMarch 9, 1984. The Radio Research Laboratories (Tokyo, Japan) then requestedand received permission to reactivate ISIS 1. Regular ISIS 1 operations werestarted from Kashima, Japan, in early August 1984. ISIS 1 was deactivatedeffective January 24, 1990.                  - Auxiliary Information -    Launch Date and Time :  1969-01-30 06:43:00    Epoch Date and Time  :  1969-02-04    Apogee (km or AU):      3526.

text: STILT, the Stochastic Time-Inverted Lagrangian Transport model, is a Lagrangian particle dispersion model (LPDM) for atmospheric transport. Its primary purpose is to derive the upstream influence region on atmospheric measurement locations. In other words, it is a fast tool to retrieve the adjoint of tracer transport, i.e. the sensitivity of atmospheric tracer mixing ratio measured at receptor point with respect to upstream surface fluxes. STILT is driven by meteorological fields (most important wind fields) from a variety of weather prediction models (ECMWF, WRF, RAMS, ...), for both analysis of past observations or for measurement planning purposes using forecasts. STILT includes turbulence as a stochastic process.

STILT is being used by a growing community for interpreting trace gas measurements made at ground based stations, on airborne platforms, as well as from remote sensing. Current applications of STILT focus on greenhouse gases and other trace gases, where it is used with high resolution emission inventories and biospheric flux models to provide insight on regional scale budgets.

STILT is actively developed by a group of researchers at Harvard University, MPI-Jena, University of Waterloo, and Atmospheric &amp; Environmental Research (AER).

    <skos:definition xml:lang="en">STILT, the Stochastic Time-Inverted Lagrangian Transport model, is a Lagrangian particle dispersion model (LPDM) for atmospheric transport. Its primary purpose is to derive the upstream influence region on atmospheric measurement locations. In other words, it is a fast tool to retrieve the adjoint of tracer transport, i.e. the sensitivity of atmospheric tracer mixing ratio measured at receptor point with respect to upstream surface fluxes. STILT is driven by meteorological fields (most important wind fields) from a variety of weather prediction models (ECMWF, WRF, RAMS, ...), for both analysis of past observations or for measurement planning purposes using forecasts. STILT includes turbulence as a stochastic process.STILT is being used by a growing community for interpreting trace gas measurements made at ground based stations, on airborne platforms, as well as from remote sensing. Current applications of STILT focus on greenhouse gases and other trace gases, where it is used with high resolution emission inventories and biospheric flux models to provide insight on regional scale budgets.STILT is actively developed by a group of researchers at Harvard University, MPI-Jena, University of Waterloo, and Atmospheric &amp; Environmental Research (AER).</skos:definition>

Old Value=The Federation of Digital Broad-Band Seismograph Networks (FDSN)
is a global organization. Its membership is comprised of groups
responsible for the installation and maintenance of broad-band
seismographs either within their geographic borders or
globally. Membership in the FDSN is open to all organizations
that operate more than one broadband station. Members agree to
coordinate station siting and provide free and open access to
their data. This cooperation helps scientists all over the world
to further the advancement of earth science and particularly the
study of global seismic activity.

The FDSN goals related to station siting and instrumentation are
to provide stations with good geographic distribution, recording
data with 24 bits of resolution in continuous time series with at
least a 20 sample per second sampling rate. The FDSN was also
instrumental in development of a universal standard for
distribution of broadband waveform data and related parametric
information. The Standard for Exchange of Earthquake DATA (SEED)
format is the result of that effort.

text: A small dam built across a river to control the upstream water level. Weirs have been used for ages to control the flow of water in streams, rivers, and other water bodies. Unlike large dams which create reservoirs, the goal of building a weir across a river isn’t to create storage, but only to gain some control over the water level. Over time, the term weir has taken on a more general definition in engineering to apply to any hydraulic control structure that allows water to flow over its top, often called its crest.

Old Value=Background Air Pollution Monitoring Network (BAPMoN):

A network of stations that collect rain water samples which are
sent to the Central Chemical Laboratory at Pune for complete
chemical analysis.  Acidity of rain and mineral deposition is
determined from these. Atmospheric turbidity which indicates the
columnar aerosol load of the atmosphere, is also measured at
these stations using sunphotmeters.  These data are important
for identifying the current levels of pollution as well as for
study of the long term trends in the concentration of trace
constituents of the atmosphere which may affect the environment
and induce a climate change.

text: BEACO2N is a new strategy for understanding green house gases (GHGs) and air quality at street level in near real time, giving pedestrians, companies, and policy-makers unique insight into their GHG emissions and air quality experiences. Instead of using a small number of highly sensitive instruments to measure GHGs and air quality, we blanket interesting locations with a network of sensors - called &apos;nodes&apos; -  approximately 1 mile (2km) apart from each other. Although our individual nodes are less precise than the highly sensitive traditional sensors, when working as part of a network, our nodes create a highly detailed map of CO2 and pollutants in our air. Our nodes are sampling the air for 6 gases and also aerosol in the same locations, every minute of the day. The data provides a clear route to evaluating the effectiveness of local and regional efforts to reduce GHG emissions, improve air quality, improve environmental equity and reduce the detrimental effects of emissions on public health.

    <skos:definition xml:lang="en">Climate models, also known as general circulation models or GCMs, use mathematical equations to characterize how energy and matter interact in different parts of the ocean, atmosphere, land. Building and running a climate model is complex process of identifying and quantifying Earth system processes, representing them with mathematical equations, setting variables to represent initial conditions and subsequent changes in climate forcing, and repeatedly solving the equations using powerful supercomputers.</skos:definition>

Old Value=The Global Monitoring Division (GMD) of the National Oceanic and Atmospheric Administration&apos;s Earth Science Research Laboratory (ESRL), conducts sustained observations and research related to source and sink strengths, trends and global distributions of atmospheric constituents that are capable of forcing change in the climate of Earth through modification of the atmospheric radiative environment, those that may cause depletion of the global ozone layer, and those that affect baseline air quality. ESRL accomplishes this mission primarily through long-term measurements of key atmospheric species at sites spanning the globe, including five fully-equipped Baseline Observatories. These key species include carbon dioxide, carbon monoxide, methane, nitrous oxide, surface and stratospheric ozone, halogenated compounds including CFC replacements, hydrocarbons, sulfur gases, aerosols, and solar and infrared radiation. The measurements are of the highest quality and accuracy possible, and document global ch!  anges in key atmospheric species, which are all affected by mankind, identifying sources of interannual variability. In addition, research programs in key regions, utilizing an array of platforms including aircraft, balloons, ocean vessels and towers, complement the land-based information. ESRL&apos;s data are used to assess climate forcing, ozone depletion and baseline air quality, to develop and test diagnostic and predictive models, and to keep the public, policy makers, and scientists abreast of the current state of our chemical and radiative atmosphere.

The major model characteristics include enough unevenly spaced layers to adequately represent soil temperature and soil moisture, and a multilayer parameterization of snow processes; an explicit treatment of the mass of liquid water and ice water and their phase change within the snow and soil system; a runoff parameterization following the TOPMODEL concept; a canopy photo synthesis-conductance model that describes the simultaneous transfer of CO2 and water vapor into and out of vegetation; and a tiled treatment of the subgrid fraction of energy and water balance. CLM has been extensively evaluated in offline mode and coupling runs with the NCAR Community Climate Model (CCM3).

    <skos:definition xml:lang="en">The Global Oscillation Network Group (GONG) is a community-based project to conduct a detailed study of solar internal structure and dynamics using helioseismology. In order to exploit this new technique, GONG has developed a six-station network of extremely sensitive, and stable velocity imagers located around the Earth to obtain nearly continuous observations of the SUN&apos;s &apos;five-minute&apos; oscillations, or pulsations.The site comprising the GONG Network are:Big Bear, CaliforniaCerro Tololo, ChileLearmonth, AustraliaMauna Loa, HawaiiUdaipur, IndiaObservatorio del Teide, Canary IslandsThe five-minute oscillation is a subtle effect. Individual modes may exhibit velocities of less than 0.2 meters/second, while the sum of all of the modes is only a few hundred meters/second. The ultimate intention is to have the measurements be limited by the Sun&apos;s ``random&apos;&apos; surface motions. This means developing six stable instruments capable of making imaged velocity measurements with a precision of significantly less than one meter/second - one part in ten million! A low technological risk instrument based on a Michelson interferometer was selected, and it will be supported by a highly automated, portable installation, somewhat reminiscent of a spacecraft experiment.Each station in the network will produce more than 200 megabytes of data every day. Over the three year observing run, the raw data will exceed one terabyte, and the various processed data sets will exceed this several-fold. To keep up with the data flow, a pipe-line capable of roughly 6 Megaflops has be established to do the bulk processing and provide subsets of the data for the scientific community. Because of the widespread scientific participation, distributed data, software and analysis tools will be provided. Thus, in addition to a central facility, participating scientists will have access to readily transportable data archives and software, as well as shared analysis programs at their home institutions.Group: Platform_Details   Entry_ID: GONG NETWORK   Group: Platform_Identification      Platform_Category: In Situ Land-based Platforms      Platform_Series_or_Entity: SOLAR/SPACE MONITORING STATIONS      Short_Name: GONG NETWORK      Long_Name: Global Oscillation Network Group   End_Group   Group: Synonymous_Platform_Names      Short_Name: GONG   End_Group   Group: Platform_Associated_Instruments      Short_Name: INTERFEROMETERS   End_Group   Creation_Date: 2007-12-10   Online_Resource: http://gong.nso.edu/info/   Sample_Image: http://gong.nso.edu/instrument/outside_shelter.jpgEnd_Group</skos:definition>

text: The TIROS Program (Television Infrared Observation Satellite) was NASA&apos;s first experimental step to determine if satellites could be useful in the study of the Earth. At that time, the effectiveness of satellite observations was still unproven. Since satellites were a new technology, the TIROS Program also tested various design issues for spacecraft: instruments, data and operational parameters. The goal was to improve satellite applications for Earth-bound decisions, such as &quot;should we evacuate the coast because of the hurricane?&quot;.

The TIROS Program&apos;s first priority was the development of a meteorological satellite information system. Weather forecasting was deemed the most promising application of space-based observations.

TIROS proved extremely successful, providing the first accurate weather forecasts based on data gathered from space. TIROS began continuous coverage of the Earth&apos;s weather in 1962, and was used by meteorologists worldwide. The program&apos;s success with many instrument types and orbital configurations lead to the development of more sophisticated meteorological observation satellites.

Old Value=The IRIS Global Seismographic Network (GSN) is one of the four major components
of the IRIS Consortium. The goal of the GSN is to deploy 128 permanent seismic
recording stations uniformly over the earth&apos;s surface.

Stations:

As of 2003 the IRIS GSN was made up of over 128 stations with affiliations to
USGS, UCSD/IDA, GEOFON, Pacific21, NCDSN, GEOSCOPE, MedNet, BGR, BFO, USNSN,
BDSN, TriNet, AFTAC and several other national and international networks.
Eight new stations are planned for completion in 2003-2005.

The IRIS GSN stations continuously record seismic data from very broad band
seismometers at 20 samples per second, and to provide for high-frequency (40
sps) and strong-motion (1 and 100 sps) sensors where scientifically warranted.
It is also the goal of the GSN to provide for real-time access to its data via
Internet or satellite. Over 75% of the IRIS GSN stations meet this goal.

    <skos:prefLabel xml:lang="en">ECHO-1</skos:prefLabel>
    <skos:definition xml:lang="en">The Echo satellites were NASA&apos;s first experimental communications satellite project. Each spacecraft was a large metallized balloon designed to act as a passive communications reflector to bounce communication signals transmitted from one point on Earth to another. Following the failure of the launch vehicle carrying Echo 1, Echo 1A (commonly referred to as Echo 1) was successfully orbited, and was used to redirect transcontinental and intercontinental telephone, radio, and television signals. The success of Echo 1A proved that microwave transmission to and from satellites in space was understood and demonstrated the promise of communications satellites. The vehicle also provided data for the calculation of atmospheric density and solar pressure due to its large area-to-mass ratio. Echo 1A was visible to the unaided eye over most of the Earth (brighter than most stars) and was probably seen by more people than any other man-made object in space. Echo 2 continued the passive communications experiments, and also investigated the dynamics of large spacecraft and was used for global geometric geodesy. Although NASA abandonded passive communications systems in favor of active satellites following Echo 2, the Echo systems demonstrated several ground station and tracking technologies that would be used by active systems. Echo 1A reentered on May 24, 1968 followed by Echo 2 on June 7, 1969. Spacecraft 1, 1A: each was a 30.5 m diameter balloon made of 0.0127 mm thick mylar polyester film. A set of 107.9-MHz beacon transmitters were carried for telemetry. The transmitters were powered by five nickel-cadmium batteries that were charged by 70 solar cells mounted on the balloon. 2: a 41.1 m diameter mylar balloon that used an improved inflation system to improve the balloon&apos;s smoothness and sphericity. Instrumentation included temperature sensors to monitor the balloon&apos;s skin temperature and pressure sensors to monitor the balloon&apos;s internal pressure. A beacon system, consisting of two transmitter assemblies, provided tracking and telemetry signals. The beacon system used solar cell panels for power and had a minimum power output of 45 mW at 136.17 MHz and 136.02 MHz.

text: The Modern-Era Retrospective analysis for Research and Applications (MERRA) dataset was released in 2009. It is based on a version of the GEOS-5 atmospheric data assimilation system that was frozen in 2008. MERRA data span the period 1979 through February 2016 and were produced on a 0.5° × 0.66° grid with 72 layers. MERRA was used to drive stand-alone reanalyses of the land surface (MERRA-Land) and atmospheric aerosols (MERRAero).

It is based on a version of the GEOS-5 atmospheric data assimilation system that was frozen in 2008. MERRA data span the period 1979 through February 2016 and were produced on a 0.5° × 0.66° grid with 72 layers. MERRA was used to drive stand-alone reanalyses of the land surface (MERRA-Land) and atmospheric aerosols (MERRAero).</skos:definition>

text: The City of Madison is leading a new collaborative project to install a city-wide network of air quality sensors to help understand air pollution in our community. These sensors will measure particulate matter pollution - small particles that can cause heart and breathing problems. Once installed, air quality data from the network will help our community understand the amount, location, and potential sources of particulate matter pollution. Better information about air quality will help us know when to take action to protect our health and help our community develop strategies to reduce pollution where it is highest. The City is partnering with The Foundation for Black Women’s Wellness, Latino Health Council of Dane County, The Hmong Institute, University of Wisconsin-Madison and Public Health Madison and Dane County. This work is funded by a grant from the U.S. Environmental Protection Agency.

text: The vision of Deploying Real-Time Multi-Pollutant Sensors (RAMP) is to test the ability of a distributed network of air pollutant sensors to be used as a decision tool for local policymakers and a source of community information on environmental health. The project tests the following primary hypothesis: Networks of lower-cost air pollutant sensors can be leveraged to inform quantitative, data-driven policy decisions and to track progress with municipal sustainability goals. The team leverages a network of low-cost sensors that measure multiple air pollutants (RAMPs). We use RAMP data (2016-present) to quantify changes in vehicle emissions in the City of Pittsburgh, and reductions in air pollution in both Pittsburgh and Millvale. The City’s Climate Action Plan aims to reduce greenhouse gas emissions from motor vehicles and will evaluate progress with surveys. The RAMPs help quantitatively determine whether expected emissions reductions have occurred and will occur into the future.

centered around the 48 conterminous states, while the Local Analysis and Prediction System (LAPS) was for domains of 500 km by 500 km. In the MAPS effort, an isentropic coordinate model is used for four
dimensional assimilation and short range forecast. During FY 1990, the basic MAPS system was installed at the National Meteorological Center (NMC) for use by the National Weather Service (NWS). Within
FSL, the upper air analysis was run on a three-hour cycle, and was being extended to a one-hour cycle. The LAPS system was being used for high resolution atmospheric diagnosis, and is testing models for
very short range prediction.

The LAPS system was being used for high resolution atmospheric diagnosis, and is testing models forvery short range prediction.</skos:definition>

text: We document the development and simulation characteristics of the next generation modeling system for seasonal to decadal prediction and projection at the Geophysical Fluid Dynamics Laboratory (GFDL). SPEAR (Seamless System for Prediction and EArth System Research) is built from component models recently developed at GFDL—the AM4 atmosphere model, MOM6 ocean code, LM4 land model, and SIS2 sea ice model. The SPEAR models are specifically designed with attributes needed for a prediction model for seasonal to decadal time scales, including the ability to run large ensembles of simulations with available computational resources. For computational speed SPEAR uses a coarse ocean resolution of approximately 1.0° (with tropical refinement). SPEAR can use differing atmospheric horizontal resolutions ranging from 1° to 0.25°. The higher atmospheric resolution facilitates improved simulation of regional climate and extremes. SPEAR is built from the same components as the GFDL CM4 and ESM4 models but with design choices geared toward seasonal to multidecadal physical climate prediction and projection. We document simulation characteristics for the time mean climate, aspects of internal variability, and the response to both idealized and realistic radiative forcing change. We describe in greater detail one focus of the model development process that was motivated by the importance of the Southern Ocean to the global climate system. We present sensitivity tests that document the influence of the Antarctic surface heat budget on Southern Ocean ventilation and deep global ocean circulation. These findings were also useful in the development processes for the GFDL CM4 and ESM4 models.

The first, the Lund-Potsdam-Jena (LPJ) model, is a dynamic global vegetation model (DGVM) that provides a prognostic understanding of how vegetation communities interact with the environment and each other, taking into account impacts from climate, soil resources, texture, and land use change. The second model, PROSAIL, is a radiative transfer model (RTM), which is also a mathematically-based model that is used to understand how energy (light) interacts with a medium, in this case, soil and vegetation. PROSAIL itself is a combination of two models, a leaf-level model, PROSPECT (from the French Propriétés Spectrales, or Spectral Properties), and SAIL (Scattering by Arbitrarily Inclined Leaves).

    <skos:definition xml:lang="en">The rocket was launched from Plesetsk Space Center, 800kilometers northeast of Moscow, and successfully brought thesatellites on board, including OHB?s micro-satelliteRUBIN-4-dsi, into their respective orbits. OHB, via itssubsidiary COSMOS International Satellitenstart GmbH, organizedand carried out the services associated with the launch of SouthKorean research satellite KAISTSAT-4, which was also on board.The orbital telematics experiment Rubin-4-dsi developed by OHGis located on the upper stage of the COSMOS and transmitsinformation on the rocket?s acceleration, vibration load andposition. Rubin will transmit this information to earth viae-mail using the Orbcomm satellite communications system. Inthis way, it will be possible to track the rocket in orbitreliably and without any data loss.RUBIN-4-dsi is the fourth micro-satellite from the RUBIN seriesdeveloped and maintained by OHB. The first was launched in July2000 and transmitted approximately 1,600 e-mails with measuringdata from outer space. RUBIN-2, a much more complex follow-upmodel, and RUBIN-3 came at the end of 2002.Among other things, RUBIN communications technology can infuture be used for communicating with satellites orbiting closeto the earth without any data loss. Moreover, RUBIN can provideearly information on whether a satellite was successfully putinto orbit.For further information please contact:Danela SellOHB-System AGCommunication &amp; Public Relationsfon: +49.421.2020-620fax: +49.421.2020-700mail: dsell&amp;#64ohb-system.deAdditional information available at&apos;http://www.fuchs-gruppe.com/ohb-system/News/presse/2709_03.html&apos;</skos:definition>

Old Value=The Automated Surface Observing Systems (ASOS) program is a joint effort of the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the Department of Defense (DOD). The ASOS systems serves as the nation&apos;s primary surface weather observing network. ASOS is designed to support weather forecast activities and aviation operations and, at the same time, support the needs of the meteorological, hydrological, and climatological research communities.

With the largest and most modern complement of weather sensors, ASOS has significantly expanded the information available to forecasters and the aviation community. The ASOS network has more than doubled the number of full-time surface weather observing locations. ASOS works non-stop, updating observations every minute, 24 hours a day, every day of the year.

Elements Reported:

1. Sky condition:cloud height and amount (clear, scattered,
broken, overcast) up to 12,000 feet

2. Visibility (to at least 10 statute miles)

3. Basic present weather information: type and intensity for
rain, snow, and freezing rain

4. Obstructions to vision: fog, haze

5. Pressure: sea-level pressure, altimeter setting

6. Ambient temperature, dew point temperature

7. Wind: direction, speed and character (gusts, squalls)

8. Precipitation accumulation

9. Selected significant remarks including- variable cloud
height, variable visibility, precipitation beginning/ending
times, rapid pressure changes, pressure change tendency, wind
shift, peak wind

text: A three-dimensional tracer transport model is used to investigate the annual cycle of atmospheric CO2 concentration produced by seasonal exchanges with the terrestrial biosphere. The tracer model uses winds generated by a global general circulation model to advect and convect CO2; no explicit diffusion coefficients are employed. A biospheric exchange function constructed from a map of net primary productivity, and Alzvedo&apos;s (1982) seasonality of CO2 uptake and release closely simulates the annual cycles at coastal stations. The results show that zonal homogeneity in surface CO2 concentrations can never be achieved at mid-latitudes where the time scale for zonal mixing is longer than the time scale for biospheric exchange. Analysis of the zonal mean balance in the lower troposphere reveals that atmospheric transport processes may later the CO2 response to local biospheric exchanges by 50% or more. Hence year-to-year variation of the annual CO2 cycle may result from the natural variability of the atmospheric circulation as well as from changes in the sources and sinks.

text: The Community Atmosphere Model with Chemistry (CAM-chem) is a component of the NCAR Community Earth System Model (CESM) and is used for simulations of global tropospheric and stratospheric atmospheric composition.  CAM-chem uses the MOZART chemical mechanism, with various choices of complexity for tropospheric and stratospheric chemistry.  The first version of CAM-chem is described in Lamarque et al. (2012), CAM-chem as used for CCMI and HTAP is described in Tilmes et al. (2016), CAM-chem in CESM1.2 is described in Tilmes et al. (2015).

CESM2, including CAM6-chem, is the current version. This version includes a significantly updated tropospheric chemistry mechanism (MOZART-T1) [Emmons et al., 2020], along with a volatility basis set (VBS) parameterization for the formation of secondary organic aerosols (SOA) [Tilmes et al., 2019]. CESM2.0 and CESM2.1 were used for CMIP6 simulations, so if you are interested in simulating results to be consistent with those results it is recommended to use CESM2.1.

text: The NCEP/NCAR Reanalysis 1 project is using a state-of-the-art analysis/forecast system to perform data assimilation using past data from 1948 to the present. A large subset of this data is available from PSL in its original 4 times daily format and as daily averages. However, the data from 1948-1957 is a little different, in the regular (non-Gaussian) gridded data. That data was done at 8 times daily in the model, because the inputs available in that era were available at 3Z, 9Z, 15Z, and 21Z, whereas the 4x daily data has been available at 0Z, 6Z, 12Z, and 18Z. These latter times were forecasted and the combined result for this early era is 8x daily. The local ingestion process took only the 0Z, 6Z, 12Z, and 18Z forecasted values, and thus only those were used to make the daily time series and monthly means here.

The spacecraft consisted of alternating layers of aluminum foil and plastic film. Uniformly distributed over the aluminum surface were 5.1-cm dots of white paint for thermal control. Explorer 9 carried a 136-MHz beacon for tracking purposes. The beacon failed on the first orbit however, and the SAO Baker-Nunn camera network had to be relied upon for tracking.

text: The MERRA-NOBM biogeochemical reanalysis used the NASA Ocean Biogeochemical Model (NOBM) coupled with the Poseidon ocean general circulation model to produce distributions of phytoplankton and ocean carbon. The reanalysis used external forcing fields from the MERRA reanalysis.

Total chlorophyll (ocean-color) data derived from NASA&apos;s SeaWiFS, MODIS and NPP-VIIRS observations were assimilated to constrain the phytoplankton distributions. The model contains four explicit phytoplankton taxonomic groups: diatoms, cyanobacteria, chlorophytes, and coccolithophores, to represent the large scale biodiversity of the global oceans. Carbon and nutrient distributions, as well as fluxes of carbon between atmosphere and oceans, are included in this product.

text: SPOT is a commercial high-resolution optical Earth imaging satellite system operating from space. It is run by Spot Image, based in Toulouse, France. It was initiated by the CNES (Centre national d&apos;études spatiales – the French space agency) in the 1970s and was developed in association with the SSTC (Belgian scientific, technical and cultural services) and the Swedish National Space Board (SNSB). It has been designed to improve the knowledge and management of the Earth by exploring the Earth&apos;s resources, detecting and forecasting phenomena involving climatology and oceanography, and monitoring human activities and natural phenomena. The SPOT system includes a series of satellites and ground control resources for satellite control and programming, image production, and distribution.

New Value=The Great Lake Primary Productivity Model (GLPPM) was developed under the NASA ROSES Carbon Monitoring System Program as well as under Great Lakes Observing System (GLOS) funding to help determine if and when the Great Lakes act as sources or sinks of carbon to the atmosphere. The GLPPM uses satellite-retrieved concentrations of chlorophyll a, Photosynthetically Available Radiation (PAR), and light extinction from the MTRI Color Producing Agent Algorithm (CPA-A) (Shuchman et al. 2013). The model also utilizes Photosynthetic Irradiance (PI) parameters derived from years of consistent field observations to estimate phytoplankton carbon fixation rates. The model is the next generation implementation of the model proposed by Fee (1973) and Lang and Fahnenstiel (1996). The GLPPM has been tested with in situ model estimates (Fahnenstiel et al. 2010) and displayed good agreement throughout the vegetative season (Shuchman et al. 2013).</skos:changeNote>

text: Parcel trajectories are often calculated to obtain an appreciation of the history of air masses (e.g. Fuelburg et al., 1996). The direction and length of trajectories are useful in diagnosing processes that may affect particular air masses under certain conditions. In this regard it is important that parcel trajectories are determined accurately.

The three-dimensional (3D) algorithm presented here (traj3d) builds on the two-dimensional (2D) model of Law (1993) and reported in application by Perrin and Simmonds (1995). From a specified parcel location in the atmosphere, xn at time n, a finite integral is solved to advect the parcel and generate the trajectory path. Given the 3D wind v(xn) the governing prognostic equation for the trajectory path over a short time interval Δt is  xn+1 = xn + v Δt . The wind at a given point is found by cubically interpolating from a spatial grid then linearly in time. For back trajectories the wind direction is reversed. The finite integral is solved using a fourth-order Runge-Kutta scheme to obtain an estimate of the wind. This method is considerably more accurate for trajectory calculations than a simple first-order approach. For mathematical details about the 3D algorithm see Noone and Simmonds (1999) and Barras and Simmonds (2009).

We present an implementation of the 3D algorithm in Fortran 77 that is suitable for any platform given an appropriate compiler. A precompiled Linux version is also available. The input to the program is a simple binary format referred to as CMP. At present the input data (usually 3D winds) are limited to constant pressure levels (e.g. 1000, 925, 850 hPa etc) as is the case with the commonly available reanalysis products e.g. NCEP reanalysis. The output of the program is a NetCDF file (and therefore NetCDF libraries need to be accessible for compilation) and this may be imported into many software packages e.g. Matlab, NCL, for subsequent analysis and plotting. We include some utilities to convert from NetCDF (a common format for 3D meteorological fields like winds) to CMP as well as plotting the trajectories based on NCAR Graphics/NCL.

Although intended for computing 3D trajectories the algorithm is equally applicable to 2D trajectory studies e.g. 10 m winds, or a single pressure level e.g. 500 hPa. Finally, it is possible to interpolate auxiliary variables e.g. air temperature, to the trajectory positions and include these in the output NetCDF file.

text: Satellite Navigation is based on a global network of satellites that transmit radio signals from medium earth orbit. Users of Satellite Navigation are most familiar with the 31 Global Positioning System (GPS) satellites developed and operated by the United States. Three other constellations also provide similar services. Collectively, these constellations and their augmentations are called Global Navigation Satellite Systems (GNSS). The other constellations are GLONASS developed and operated by the Russian Federation, Galileo developed and operated by the European Union, and BeiDou, developed and operated by China. All providers have offered free use of their respective systems to the international community. All providers have developed International Civil Aviation Organization (ICAO) Standards and Recommended Practices to support use of these constellations for aviation.

text: The CMS Methane (CH4) Flux for North America data set contains estimates of methane emission in North America based on an inversion of the GEOS-Chem chemical transport model constrained by Greenhouse Gases Observing SATellite (GOSAT) observations. The nested approach of the inversion enables large point sources to be resolved while aggregating regions with weak emissions and minimizing aggregation errors. The emission sources are separated into 12 different sectors as follows: Total, Oil/Gas, Coal, Cows, Waste (Landfills+ Wastewater), Biofuel, Rice, Other Anthropogenic, Biomass Burning, Wetlands, Soil Absorption, Other Natural. More details about the algorithm and error characterization can be found in Turner, Jacob, Wecht, et al. 2015.

text: FLEXPART (“FLEXible PARTicle dispersion model”) (Stohl et al., 2005) is a Lagrangian transport and dispersion model (Lin et al., 2012) suitable for the simulation of atmospheric transport processes. Applications
range from the dispersion of radionuclides or air pollutants, over the establishment of flow climatologies, to the analysis of Earth’s water cycle. FLEXPART also produces output suitable for inverse modeling of emission
fluxes, e.g., of greenhouse gases or volcanic ash.

Old Value=Sudden Ionospheric Disturbance Stations (SID) consists of solar observers who monitor very low frequency (VLF) radio stations for sudden enhancements of their signals. Earth&apos;s ionosphere reacts to the intense x-ray and ultraviolet radiation released during a solar flare. The ionospheric disturbance enhances VLF radio propagation. By monitoring the signal strength of a distant VLF transmitter, sudden ionospheric disturbances (SIDs) are recorded and indicate a recent solar flare event.

All SID monitoring stations are homebuilt by the observers. Instructions for constructing the VLF receiver and antenna can be obtained from the AAVSO Solar Division chairman. The receiver design has progressed remarkably as the SID program participants have been inspired to improve signal sensitivity and noise rejection. Recent SID station receivers follow a design developed by SID Technical Coordinator Art Stokes. The Stokes Gyrator receiver can be built and tuned by anyone with simple soldering skills. A small indoor loop antenna captures the radio wave for amplification and rectification by the receiver. The SID station operates unattended until the end of each month. Recordings are then analyzed for the beginning, end, and duration of SID events.

New Value=The Noah-MP&apos;s performance is evaluated at various local sites using high temporal frequency data sets, and results show the advantages of using multiple optional schemes to interpret the differences in modeling simulations. The second paper focuses on ensemble evaluations with long-term regional (basin) and global scale data sets. The enhanced conceptual realism includes (1) the vegetation canopy energy balance, (2) the layered snowpack, (3) frozen soil and infiltration, (4) soil moisture-groundwater interaction and related runoff production, and (5) vegetation phenology. Sample local-scale validations are conducted over the First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment (FIFE) site, the W3 catchment of Sleepers River, Vermont, and a French snow observation site. Noah-MP shows apparent improvements in reproducing surface fluxes, skin temperature over dry periods, snow water equivalent (SWE), snow depth, and runoff over Noah LSM version 3.0. Noah-MP improves the SWE simulations due to more accurate simulations of the diurnal variations of the snow skin temperature, which is critical for computing available energy for melting. Noah-MP also improves the simulation of runoff peaks and timing by introducing a more permeable frozen soil and more accurate simulation of snowmelt. We also demonstrate that Noah-MP is an effective research tool by which modeling results for a given process can be interpreted through multiple optional parameterization schemes in the same model framework.</skos:changeNote>

    <skos:definition xml:lang="en">The Pioneer Venus Orbiter was inserted into an elliptical orbit around Venus onDecember 4, 1978. The Orbiter was a flat cylinder 2.5 m in diameter and 1.2 mhigh. All instruments and spacecraft subsystems were mounted on the forward endof the cylinder, except the magnetometer, which was at the end of a 4.7 m boom.A solar array extended around the circumference of the cylinder. A 1.09 mdespun dish antenna provided S and X band communication with Earth.The Pioneer Venus Orbiter carried 17 experiments (with a total mass of 45 kg):    * a cloud photopolarimeter to measure the vertical distribution of theclouds    * a surface radar mapper to determine topography and surfacecharacteristics    * an infrared radiometer to measure IR emissions from the Venus atmosphere    * an airglow ultraviolet spectrometer to measure scattered and emitted UVlight    * a neutral mass spectrometer to determine the composition of the upperatmosphere    * a solar wind plasma analyzer to measure properties of the solar wind    * a magnetometer to characterize the magnetic field at Venus    * an electric field detector to study the solar wind and its interactions    * an electron temperature probe to study the thermal properties of theionosphere    * an ion mass spectrometer to characterize the ionospheric ion population    * a charged particle retarding potential analyzer to study ionosphericparticles    * two radio science experiments to determine the gravity field of Venus    * a radio occultation experiment to characterize the atmosphere    * an atmospheric drag experiment to study the upper atmosphere    * a radio science atmospheric and solar wind turbulence experiment    * a gamma ray burst detector to record gamma ray burst events From Venus orbit insertion to July 1980, periapsis was held between 142 and 253km (at 17 degrees north latitude) to facilitate radar and ionosphericmeasurements. The spacecraft was in a 24 hour orbit with an apoapsis of 66,900km. Thereafter, the periapsis was allowed to rise (to 2290 km at maximum) andthen fall, to conserve fuel. In 1991 the Radar Mapper was reactivated toinvestigate previously inaccessible southern portions of the planet. In May1992 Pioneer Venus began the final phase of its mission, in which the periapsiswas held between 150 and 250 km until the fuel ran out and atmospheric entrydestroyed the spacecraft the following August.

text: Noah-MP is a land surface model (LSM) using multiple options for key land-atmosphere interaction processes (Niu et al., 2011). Noah-MP contains a separate vegetation canopy defined by a canopy top and bottom, crown radius, and leaves with prescribed dimensions, orientation, density, and radiometric properties. The canopy employs a two-stream radiation transfer approach along with shading effects necessary to achieve proper surface energy and water transfer processes including under-canopy snow processes (Dickinson, 1983; Niu and Yang, 2004). Noah-MP contains a multi-layer snow pack with liquid water storage and melt/refreeze capability and a snow-interception model describing loading/unloading, melt/refreeze capability, and sublimation of canopy-intercepted snow (Yang and Niu 2003; Niu and Yang 2004). Multiple options are available for surface water infiltration and runoff and groundwater transfer and storage including water table depth to an unconfined aquifer

text: Advances in air pollution sensor technology have enabled the development of small and low cost systems to measure outdoor air pollution. The deployment of numerous sensors across a small geographic area would have potential benefits to supplement existing monitoring networks and significantly reduce the cost of longer-term community air pollution studies, if the data quality were sufficient. To understand the field performance and utility of the next generation of air quality monitoring instrumentation, the Community Air Sensor Network (CAIRSENSE) project deploys low cost, continuous and commercially-available monitoring methods for criteria pollutants – including PM2.5, O3 and NO2 – in suburban Atlanta, GA. The study includes two aspects – 1) placement of multiple copies of the same sensor at the South Dekalb NCore site for side-by-side comparison with regulatory instruments, 2) testing the utility of a low cost wireless sensor network by installing multiple sensor nodes equipped with radio transmitters that locally transmit the data, followed by uploading using cellular communications. With a total of approximately 30 sensor devices running simultaneously and collecting one minute data, some of multiple pollutants at once, the data set under evaluation totals well over 2.5 million individual sensor readings for comparison against NCore station instrumentation, to evaluate precision of identical sensors, and to understand the influence of environmental conditions and local sources on sensor trends.

MINTS affiliates include experts from the UTD departments of physics, geosciences, electrical engineering, and computer science with a broad range of background expertise. The combined experience of the center affiliates is more than a century.

The vision of MINTS is a holistic intelligent synergy of integrated targeted observations from multiple platforms on multiple spatial and temporal scales, together with state of the art compression and visualization systems for the distribution and comprehensive analysis of complete datasets. By combining instruments on satellites and robotic vehicles (in air, land, and sea) that can be directed in real time we can capture observations on multiple parameters on multiple spatial and temporal scales appropriate to a wide range of problems. This provides a high level of situational awareness.

MINTS is able to provide intelligent sensing solutions for your application, whether it concerns natural resources, environment and health, safety and security, or transportation and geospatial applications.

text: Located at the Kennedy Space Center, the Lightning Detection and Ranging (LDAR) system consists of seven antennas that detect electromagnetic pulses at 66 MHz, which allows it to detect 99% of all flashes (both intracloud and cloud-to-ground flashes) within 10 km of the antenna network. The accuracy of source locations is a function of position relative to the receiving array, generally decreasing (particularly along
the radial axis with respect to the array center) with distance. The RMS error for LDAR lightning source locations varies from 100 meters inside the network to about 10 km at a range of 90 km (about 1/3 the width of the Florida peninsula).

This data set is one of several NCEP sets of model data archived at NCEI. Historical data set DSI-6140 consists of two subgroups of NCEP model data: NGM and MRF for the time period January 1, 1991 through April 15, 1997. Geographic coverage is the 48 contiguous states of the United States of America, plus adjacent waters and southern Canada. Major parameters provided by NGM are ice covered water areas (yes/no), snow covered areas (yes/no), terrain height, mean sea level pressure, convective precipitation, total precipitation, exchange coefficient at surface, upward turbulent flux of sensible heat, upward turbulent flux of water, surface pressure, number of mixed layers next to surface, u component of wind, v component of wind, vertical velocity, specific humidity, and temperature. Parameters provided by MRF are surface temperature, geopotential height, and relative humidity. DSI-6140 is the historical precursor data set to digital data set DSI-6141, NCEP EDAS and GDAS (FNL) Model Data, also archived at NCEI.

text: The WeatherStation 200WX is the best choice for mobile, land-based, weather-monitoring applications. Sensor rich, in a durable, rugged, small housing that is IPX6 rated, means the 200WX can be used on moving platforms such as TV-news and military vehicles.

Knowing the theoretical wind speed and direction is important and often mission-critical. The 200WX calculates the theoretical wind speed and direction based upon the apparent wind (the wind you would feel on your hand if you held it out while moving), speed of the vehicle, and vehicle heading. Its internal 10 Hz GPS and three-axis electronic compass provide heading, position, speed-over-ground, and course-over-ground functionality that is necessary for theoretical wind-data processing on a moving vehicle.

The 3D compass with dynamic stabilization provided by the three-axis rate gyro enhances the rate-of-turn data. The patented 200WX maintains dynamic compass performance in hilly and mountainous terrain—common in military situations.

Old Value=Global Atmospherics, Inc&apos;s large-area Lightning Position and Tracking System (LPATS) is a highly-accurate and sophisticated computer-based system using a time-of-arrival (TOA) technique for locating cloud-to-ground lightning strokes.  This system has been installed throughout the U.S. to form the LPATS National Network (LN2).  The precise time that lightning touches the ground is monitored to sub microsecond accuracy at several receiver sites simultaneously. Available data include stroke position, energy, rise time, probability, counting, and ranging, along with color tracking, time of incidence, and storm historic events on a national or regional scale.  LPATS networks also currently exist in Europe, South America, and Asia.

text: To understand the global surface energy budget is to understand climate. Because it is impractical to cover the earth with monitoring stations, the answer to global coverage lies in reliable satellite-based estimates. Efforts are underway at NASA and universities to develop algorithms to do this, but such projects are in their infancy. In concert with these ambitious efforts, accurate and precise ground-based measurements in differing climatic regions are essential to refine and verify the satellite-based estimates, as well as to support specialized research.

To fill this niche, the Surface Radiation Budget Network (SURFRAD) was established in 1993 through the support of NOAA&apos;s Office of Global Programs. The SURFRAD mission is clear; its primary objective is to support climate research with accurate, continuous, long-term measurements of the surface radiation budget over the United States. This differs from DOE&apos;s ARM/SGP site, where surface radiation budget measurements are also being made, in that ARM uses clustered measurements over a limited area for process-oriented studies.

text: The Community Climate Model (CCM) was created by NCAR in 1983 as a freely available global atmosphere model for use by the wider climate research community. The formulation of the CCM has steadily improved over the past two decades, computers powerful enough to run the model have become relatively inexpensive and widely available, and usage of the model has become widespread in the university community, and at some national laboratories.

A limitation of the original CCM was that it did not include models of the global ocean and sea ice. Accordingly, in 1994, NCAR scientists submitted a plan to National Science Foundation (NSF) to develop and use a Climate System Model (CSM) that was to include models of the atmosphere, land surface, ocean, and sea ice. These components were to be coupled without resorting to any &quot;flux adjustments.&quot; The plan was to focus initially on the physical aspects of the climate system, and then in a subsequent version to improve biogeochemistry and coupling to the upper atmosphere. The first phase of this project was the model development by the NCAR staff, after which the model and associated data sets were to be made available to the scientific community. In addition, a new governance structure was promised, in which the interested scientific community would be given a fair opportunity to participate in all aspects of the CSM. NSF approved the plan, and model development began immediately.

In May 1996, the first CSM Workshop was held in Breckenridge, Colorado. At this workshop the CSM components and the results of an early equilibrium climate simulation were presented. Working groups began to form, and the nature of future CSM governance was discussed. At the final plenary session of the workshop, the proposed management structure was discussed, modified, and adopted. At that point, the second phase of CSM, including full participation of the scientific community, had begun.

The period since this 1996 workshop has been a time of substantial organizational progress. A Scientific Steering Committee (SSC) has been formed to lead the CSM activity, working groups have been producing useful output, and the previously existing Climate Modeling, Analysis and Prediction (CMAP) Advisory Council has been reorganized as the CSM Advisory Board (CAB). In addition to support from NSF, interest in the CSM from other agencies, notably the Department of Energy (DOE) and NASA, has developed. While working toward the second version of CSM, we believed that it was also time to recognize the community of users and sponsors by changing the name of the model to the Community Climate System Model (CCSM).

text: The Second generation GLobal Imager (SGLI) on GCOM-C1 is an optical sensor capable of multi-channel observation at wavelengths from near-UV to thermal infrared wavelengths (380nm to 12µm.) SGLI also has polarimetry and forward / backward observation functions at red and near infrared wavelengths. SGLI obtains global observation data once every 2 or 3 days, with resolutions of 250m to 1km.

The SGLI observations will improve our understanding of climate change mechanisms through long-term monitoring of aerosols and clouds, as well as vegetation and temperatures, in the land and ocean regions. These observations will also contribute to enhancing the prediction accuracy of future environmental changes by improving sub-processes in numerical climate models. SGLI-derived phytoplankton and aerosol distributions are also used for mapping fisheries and for monitoring the transport of yellow dust and/or wildfire smoke.

text: The NASA Langley Beechcraft UC-12B Huron (NASA 528) is an all-metal, twin-turboprop research aircraft.  The UC-12B aircraft is a military version of a Beechcraft B200 King Air.  NASA Langley acquired this aircraft in 2007 from the U.S. Marine Corps.  The aircraft has been modified with two nadir-viewing ports:  29.5 x 29.5-in. in the forward section of the passenger cabin and 26.75 x 22.5 in. in the aft section.  These downward-looking portals allow the use of a wide variety of optical, laser, or R-F based devices that might require a nadir look angle out of the aircraft.  Research-supporting subsystems, such as electrical power distribution, TCAS, GPS and satellite phone communications also have been installed.  The UC-12B aircraft also has a cargo door in the aft left side of the passenger cabin that can accommodate payloads up to 51.5 in. wide.  In past operations, the cargo door has allowed a forklift with a boom attachment to place large, heavy payloads directly into the aircraft cabin.  In its current configuration, the aircraft serves as the primary flight platform for a suite of aerosol and cloud remote-sensing instruments, including the NASA Langley Doppler Aerosol Wind LIDAR (DAWN).  The aircraft is fully IFR capable.

text: The Remotely Operated Platform for Ocean Science (ROPOS) is a remotely operated vehicle (ROV) which is able to dive down to depths of 3.1 miles (5,000 meters). The vehicle is managed and operated by the Canadian Scientific Submersible Facility , a nationally registered not-for-profit corporation established in 1995 specifically to oversee the ROPOS system.

While ROPOS is used for a variety of different types of deployments, the ROV specializes in supporting science-based missions and carries a suite of “core” observation tools  to assist with these missions. These tools include a number of video and still cameras and robust lighting to capture the otherwise dark underwater environment; two manipulator arms that can be fitted with different tools for collecting biologic and geologic samples; a multibeam system for mapping the seafloor; and much more. In fact, for each mission, ROPOS can be outfitted with up to eight additional custom-designed observation tools.

ROPOS is an unmanned submersible, controlled from a surface vessel through an armored electrical-optical umbilical cable. This means that the ROV can spend as much time underwater as needed to accomplish a mission. To date, the longest dive recorded by ROPOS lasted over 99 hours!

ROPOS and its crew conduct missions all over the world and have explored in the Pacific, Atlantic, and Indian Oceans as well as the sub-Arctic and Antarctica.

Landsat 8 (formerly called the Landsat Data Continuity Mission, or LDCM) is NASA’s eighth satellite in the Landsat series and continues the Landsat program’s critical role in monitoring, understanding and managing the resources needed for human sustainment such as food, water and forests. As our population surpasses seven billion people, the impact of human society on the planet will increase, and Landsat monitors those impacts as well as environmental changes.

With the longest unbroken data stream of Earth’s surface as seen from space, NASA’s Earth-observing Landsat fleet has provided the world with unprecedented information on land cover changes and their residual effects since 1972. The knowledge gained from 40 years of continuous data contributes to research on climate, carbon cycle, ecosystems, water cycle, biogeochemistry and changes to Earth’s surface, as well as our understanding of visible human effects on land surfaces. Building off that research, the Landsat imaging data set has, over time, led to the improvement of human and biodiversity health, energy and water management, urban planning, disaster recovery and agriculture monitoring, all resulting in incalculable benefits to the United States and world economy.

Landsat 8 joined the Landsat 7 satellite in orbit and produces stunning pictures of Earth’s surface along with a wealth of scientific data. Landsat 8 measures Earth’s surfaces in the visible, near-infrared, short wave infrared and thermal infrared, with a moderate-resolution of 15 to 100 meters, depending on spectral frequency.

Landsat 8 is a collaboration between NASA and the U.S. Geological Survey (USGS).

text: GOES 5 was launched in May 1981 and was a NASA-developed, NOAA-operated, geosynchronous, and operational spacecraft. The cylindrically shaped spacecraft measured 190.5 cm in diameter and 230 cm in length, exclusive of a magnetometer that extended an additional 83 cm beyond the cylinder shell. The primary structural members were a honeycombed equipment shelf and thrust tube. The VISSR telescope was mounted on the equipment shelf and viewed the Earth through a special aperture in the side of the spacecraft. A support structure extended radially out from the thrust tube and was affixed to the solar panels, which formed the outer walls of the spacecraft and provided the primary source of electrical power. Located in the annulus-shaped space between the thrust tube and the solar panels were stationkeeping and dynamics control equipment, batteries, and most of the SEM equipment. Proper spacecraft attitude and spin rate (approximately 100 rpm) were maintained by two separate sets of jet thrusters mounted around the spacecraft equator and activated by ground command. The spacecraft used both UHF-band and S-band frequencies in its telemetry and command subsystem. A low-power VHF transponder provided telemetry and command during launch and then served as a backup for the primary subsystem once the spacecraft attained orbit. The spin-stabilized spacecraft carried a visible infrared spin-scan radiometer atmospheric sounder, meteorological data collection and transmission system, space environment monitor, and a biaxial fluxgate magnetometer. It operated at at 75 degrees West as GOES-EAST, but on July 30, 1984, GOES 5 VAS experienced a failure, thus NOAA had to relocate GOES 6 to a more central 98 degrees West position, and to reactivate GOES 1 and GOES 4 for the acquisition and relay of VISSR information, respectively, from the western U.S. For more information on GOES satellites: http://www.ospo.noaa.gov/Operations/GOES/index.html

    <skos:definition xml:lang="en">The Space Radar Laboratory - 1  (SRL-1) was launched onboard the Space Shuttle &apos;Endeavor&apos; (STS-59) on April 9, 1994.  The SRL-1 consists of two elements: a suite of radar instruments called the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) jointly developed by NASA and DARA of Germany and ASI of Italy, and the Measurement of Air Pollution from Satellite (MAPS) instrument to measure atmospheric air pollution. SRL-1 is the first in a series of flights of this payload designed to (1) acquire radar imagery of the Earth&apos;s surface for studies in geology, geography, hydrology, oceanography, agronomy, and botany; (2) gather data for future space-borne radar systems;  and (3) provide measurements of the global distribution of carbon monoxide (CO) in the troposphere. Instruments on board include the Shuttle Imaging Radar-C (SIR-C) with multi-frequency (C- and  L-Bands), multi-polarization (HH, VV, HV, VH), and multi-incidence angle (15 to 55  degrees) capabilities thus lending itself to a wide range of earth surface applications; the X-band Synthetic Aperture Radar (X-SAR), an X-band, VV-polarized imaging radar system, built by Dornier (Germany) and Alenia (Italy) for the German Space Agency (DARA)/German Aerospace Research Establishment (DLR) and the Italian Space Agency (ASI); and, the Mapping Air Pollution from Space (MAPS) instrument for the study of global air pollution. The MAPS instrument, from NASA Langley Research Center (LaRC) is part of NASA&apos;s Mission to Planet Earth (MtPE) Program.  Four 45-Mbps data channels were recorded on special high data rate tape recorders and real-time data was transmitted to ground stations. About 50 hours each of SIR-C and X-SAR data were recorded during the mission. The combined SIR-C/X-SAR Science Team was made up of 49 members and 3 associates representing 13 countries. SIR-C/X-SAR data collection was focused on several worldwide supersites and correlated with ground and aircraft measurements. Radar data was also calibrated to allow comparisons with other operating spaceborne radars (ERS-1 SAR, JERS-1 SAR).Both SIR-C and X-SAR will use on-board tape recorders to store data as well as limited real-time transmissions to the ground. Each radar has its own on-board data handling system and each radar can have its data routed through the TDRSS for real-time transmission (Ku-band). SIR-C data are recorded in parallel and X-SAR data is recorded serially. SIR-C and X-SAR data will be preprocessed at the Payload Operations Control Center (POCC) at NASA/JSC before delivery to JPL and operations centers in Germany and Italy. Commands are sent to the SRL-1 from POCC. At mission end, data tapes recorded on-board are sent to the PI sites.The SIR-C/X-SAR part of the SRL-1 mission is expected to collect over 50 hours of data, both recorded and real-time. Real-time raw data will be pre-processed by the instrument PIs and science teams and stored at the PI sites at JPL, in Germany, and in Italy for analysis. SIR-C data will be processed at JPL using the JPL advanced digital SAR processor, leading to processed SAR images on 8-mm digital tape and on film. Plans include the production of CD-ROMs with 100 m resolution images. X-SAR data will be pre-processed within 3 months. Image products will be made available to X-SAR investigators. Both Germany and Italy will operate separate archives and processing facilities for X-SAR data. SIR-C processed data will eventually be be archived with the EOSDIS DAAC at EROS Data Center. All processed MAPS data is expected to be archived with the EOSDIS DAAC at NASA/Langley. Two additional flights of SRL are planned (August 1994 and 1995).Some SIR-C and X-SAR images are publically available on the Jet Propulsion Laboratory (JPL) FTP site: jplinfo.jpl.nasa.gov in the directory /sircxsar. The images are also available through the World Wide Web (WWW) at http://www.jpl.nasa.gov/. Both servers also have extensive information about the mission.Group: Platform_Details   Entry_ID: SRL-1   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: SRL-1      Long_Name: Space Radar Laboratory-1   End_Group   Group: Synonymous_Platform_Names      Short_Name: SRL-1   End_Group   Group: Platform_Associated_Instruments      Short_Name: X-SAR   End_Group   Creation_Date: 2008-01-28   Online_Resource: http://www-pao.ksc.nasa.gov/kscpao/chron/sts-59.htm   Group: Platform_Logistics      Launch_Date: 1994-04-09      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:prefLabel xml:lang="en">FEDSAT</skos:prefLabel>
    <skos:definition xml:lang="en">FedSat is an Australian scientific microsatellite mission, a58cm cube weighing approximately 50 kg. It was launched in early2002 from Japan by Japan&apos;s National Space Development Agency.The purpose of FedSat is to:Establish Australian capability in microsatellite technologiesDevelop expertise necessary for sustaining those industries andprofiting from themTest and develop Australian-developed intellectual propertyProvide a research platform for Australian space science,communication and GPS studies.FedSat was developed by the Cooperative Research Centre forSatellite Systems, which combines the resources and skills of 12Australian organizations. Contributions from each of the partnerorganizations are doubled by the Commonwealth Government, underits Commonwealth Government&apos;s Cooperative Research Center?sProgram. The total budget of the Centre is approximately&amp;#3660 million over 7 years, with &amp;#3620 million of thatallocated for the FedSat mission. Much of FedSat was developedin Australia by the CRCSS. Three of the six main payloads havebeen fully developed by the CRCSS, and the other three have beensupplied by overseas organizations in consultation with theCRCSS.  The satellite platform, the structure that houses andmaintains the payloads, is being provided by overseasorganizations. CRCSS engineers could have developed anAustralian platform, but given the time available fromproject-start to launch, that was not practical. CRCSS opted tocontract an overseas platform supplier, avoiding the need toreinvent established technologies.  Payloads:1. GPS Receiver: The GPS, Global Positioning System, is anAmerican network of satellites that transmit radio signalscontaining time and orbit-position codes. GPS receivers decodethe signals, and by comparing signals of up to 4 satellites withknown positions, they can derive their own locations bytriangulation. The system was designed for mainly military use,but now GPS provides many scientific and civilian applications.2. NewMag: The NewMag magnetometer is a very sensitive andrapid-sampling device for measuring the strength of the Earth&apos;smagnetic field. Earth is like a big bar magnet, with magneticfield lines emerging from the poles and far out intospace. FedSat&apos;s polar orbit crosses all these lines, so NewMagcan effectively gain a window into the whole magnetosphereregion. NewMag can also measure vibrations simultaneously withground- based magnetometers, so investigating the dynamics ofthe magnetosphere (changes in it shape due to variations in theSun), and study magnetospheric wave-propagation.3. High performance computing: The FedSat high performancecomputing payload is the world&apos;s first use of reconfigurablecomputing technology in space. Reconfigurable computers permitchange of their physical circuits via software control; newphysical circuits can be installed into a reconfigurablecomputer module by remote command. For spacecraft, thistechnology means that satellites can be rewired without havingto retrieve them.4. Ka-band transponder: The FedSat Ka-band transponder isdesigned to handle the new experimental high- frequency andhigh-capacity Ka part of the radio spectrum. The transponderprocesses signals to and from the ground in the frequencyband. The transponder incorporates CRCSS-designed GalliumArsenide monolithic microwave circuits; FedSat will spacequalify these for the first time.5. Baseband processor The baseband processor provides on-boardcomputer processing of the Ka- and UHF- band payloads. It hasbeen designed and built by the CRCSS, to operate as a low powersingle modem with flexible operation. It will also provide thechannel for satellite operations commands.6. UHF communications payload: The Ultra High Frequency bandpayload will introduce a new type of packet data service for LowEarth Orbiting satellites to obtain environmental data. Forexample, ocean buoys may transmit their data using this means toorbiting satellites, which are retransmitted back to the lab foranalysis.7. CD ROM: FedSat also carries a compact disc mounted on theside, containing the audio messages members of the Australianpublic recorded to go into space from March to August 2000. Thedisc also contains a copy of the song From Little Things, BigThings Grow, by Paul Kelly, with kind permission of the writers(Kev Carmody/Paul Kelly) and publishers (Larrikin Music,Mushroon Records).Additional information available at&apos;http://www.crcss.csiro.au/overview.htm&apos;and&apos;http://www.crcss.csiro.au/launch/launch.html&apos;[Summary provided by CSIRO]</skos:definition>

    <skos:definition xml:lang="en">The 13th flight of the Space Shuttle (STS 41-G) carried the OSTA-3 (Office of Space and Terrestrial Applications) payload designed for conducting experiments in earth remote sensing. This experiment payload consisted of 1) a Shuttle Imaging Radar (SIR-B) for studies of the earth&apos;s surface, 2) a Large Format Camera (LFC) for cartographic mappings of the earth, 3) a Measurement of Air Pollution from Satellite (MAPS) experiment to determine the distribution of CO in the atmosphere, and 4) a Feature Identification and Location Experiment (FILE) for classification of surface materials. The SIR-B was an upgraded version of the SIR-A flown on the OSTA-1 payload during the STS-2 mission (NSSDC ID 81-111A-01). The MAPS and FILE sensors were the reflies of those same instruments on the OSTA-1 payload (NSSDC ID 81-111A-04 and 81-111A-03). The mission lasted 8 days and, except for SIR-B, all instruments met their pre launch requirements.Group: Platform_Details   Entry_ID: STS-41G   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: STS-41G      Long_Name: Space Transport System STS-41G   End_Group   Group: Synonymous_Platform_Names      Short_Name: Challenger (6)   End_Group   Group: Orbit      Orbit_Inclination: 57 degrees      Perigee: 216 km      Apogee: 229 km   End_Group   Creation_Date: 2008-01-29   Online_Resource: http://www.spacefacts.de/mission/english/sts-41g.htm   Sample_Image: http://www.ksc.nasa.gov/mirrors/images/images/pao/STS41G/10061805.jpg   Group: Platform_Logistics      Launch_Date: 1984-10-05      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

Old Value=Earth Observing-1 (EO-1) is an advanced land-imaging mission that will demonstrate new instruments and spacecraft systems. EO-1 will validate technologies contributing to the significant reduction in cost of follow-on Landsat missions. Launched on a Delta 7320 from Vandenberg Air Force Base, California, November 21, 2000. EO-1 has a 1-year primary mission but was designed to operate for an additional year.

The NMP EO-1 mission includes three advanced land imaging instruments and five revolutionary cross cutting spacecraft technologies. The hyperspectral instrument is the first of its kind to provide images of land-surface in more than 220 spectral colors. The Hyperion will demonstrate the ability to perform detailed spectral mapping with high radiometric accuracy. In the future, an operational version of the Hyperion will allow complex land ecosystems to be imaged and accurately classified. The Advanced Land Imager (ALI) instrument yields almost four times better performance at only one-fourth the cost and weight of the Landsat ETM+. Finally the Linear Etalon Imaging Spectral Array/Atmospheric Corrector (LEISA/AC) is an infrared camera, which can be used to remove the effects of the atmosphere from surface pictures obtained by instruments such as the ALI on EO-1 and Landsat. This instrument will provide scientific return both in terms of improved imagery and hyperspectral sensing capabilities. It will also test a number of new technologies. Because the AC is small and adaptable to different spacecraft configurations, it is a bolt-on instrument, which can be attached to any future Earth imaging spacecraft. The three advanced imaging instruments will lead to a new generation of lighter weight, higher performance and lower cost Landsat-type Earth surface imaging instruments.

Earth Observing-1 (EO-1) is an advanced land-imaging mission that will demonstrate new instruments and spacecraft systems. 
EO-1 will validate technologies contributing to the significant reduction in cost of follow-on Landsat missions. Launched 
on a Delta 7320 from Vandenberg Air Force Base, California, November 21, 2000. EO-1 has a 1-year primary mission but was 
designed to operate for an additional year.

The NMP EO-1 mission includes three advanced land imaging instruments and five revolutionary cross cutting spacecraft 
technologies. The hyperspectral instrument is the first of its kind to provide images of land-surface in more than 220 
spectral colors. The Hyperion will demonstrate the ability to perform detailed spectral mapping with high radiometric 
accuracy. In the future, an operational version of the Hyperion will allow complex land ecosystems to be imaged and 
accurately classified. The Advanced Land Imager (ALI) instrument yields almost four times better performance at only 
one-fourth the cost and weight of the Landsat ETM+. Finally the Linear Etalon Imaging Spectral Array/Atmospheric 
Corrector (LEISA/AC) is an infrared camera, which can be used to remove the effects of the atmosphere from surface 
pictures obtained by instruments such as the ALI on EO-1 and Landsat. This instrument will provide scientific return 
both in terms of improved imagery and hyperspectral sensing capabilities. It will also test a number of new technologies.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).
Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

Old Value=ADEOS (ADvanced Earth Observation Satellite), developed by the Japanese space agency JAXA. It  was the largest satellite Japan has ever developed, having dimensions of 4 x 4 x 5 m. When antenna and the solar array paddle (approx. 3 x 24 m) were deployed, it had a span of 11m in the flight direction and 29 m in the perpendicular direction.It had a launch mass of approximatly 3500 kg and an in-orbit power generation capability of approximatly 4500W.
The spacecraft consisted of a mission module and a bus module.The bus module was made of thermally, electrically and mechanically independent units, including the Communications and Data Handling Subsystem, the Electrical Power Subsystem (EPS), the Attitude and Orbital Control Subsystem (AOCS) and the reaction Control Subsystem (RCS) for orbital maneuvers.

The mission module carried 8 instruments : Two core sensor developped by JAXA : AVNIR (Advanced Visible and Near Infrared Radiometer) and OCTS (Ocean Color and Temperature Temperature Sensor).Six Annoncement of Opportunity (AO) sensors : NSACT (NASA SCATterometer), TOMS (Total Ozone Mapping Spectometer), POLDER (POlarization and Directionality of the Earth&apos;Reflectance), IMG (Interferometric Monitor for Greenhouse Gases), ILAS (Improved Limb Atmospheric Spectrometer), RIS (Retroreflector In Space).ADEOS-1 has been launched in August 1996 by H-II launcher from Tanegashima Space Center. Ninety seconds after liftoff, the solid rocket boosters separated from the H-II vehicle and 6 minutes after liftoff, the first stage separated. Then 16 minutes after liftoff, ADEOS-1 separated from the second stage. ADEOS-1 was lost on June 1997, the 30th, due to a solar panel cable breaking.[http://smsc.cnes.fr/POLDER/index.htm]

The DMC Consortium is forming the first-ever microsatellite constellation bringing remarkable Earth observation capabilities both nationally to the individual satellite owners, and internationally to benefit world-wide humanitarian aid efforts.BILSAT experiments include two payloads designed and built by SSTL&apos;s Turkish customer, TUBITAK-ODTU-BILTEN.- The first, named COBAN, is a nine-band low resolution multi-spectral imager.- The second, named GEZGIN, is a DSP based image processing module that uses the JPEG2000 algorithm to compress images taken by BILSAT-1&apos;s on board cameras.Both of these payloads were designed and built by BILTEN engineers in the context of the KHTT (Know How Training and Transfer) programme that ran in parallel with the BILSAT project.Group: Platform_Details   Entry_ID: BILSAT-1   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: DMC-1G (Disaster Monitoring Constellation- 1st Generation)      Short_Name: BILSAT-1   End_Group   Group: Platform_Associated_Instruments      Short_Name: COBAN   End_Group   Creation_Date: 2008-08-18   Online_Resource: http://www.sstl.co.uk/Missions/BILSAT-1--Launched-2003/BILSAT-1/BILSAT-1--The-Mission   Online_Resource: http://space.skyrocket.de/doc_sdat/bilsat-1.htm   Sample_Image: http://www.skyrocket.de/space/img_sat/bilsat-1__1.jpg   Group: Platform_Logistics      Launch_Date: 2003-09-27      Launch_Site: Plesetsk Cosmodrome, Russia      Design_Life: Fulfilled mission life time in August 2006      Primary_Sponsor: Turkey/BILTEN   End_GroupEnd_Group</skos:definition>

text: The MIR deep sea submersibles operate from the RV Akademik Keldysh.

The Akademik Keldysh is the most advanced deep diving support vessel in the world. The operation is owned and operated by the PP Shirshov Institute, Russian Academy of Sciences. Its crew of scientists and technicians have worked together for over 20 years, participating in deep dive expeditions all over the world with both Pisces and MIR submersibles.

Our expedition is only made possible with the support and expertise of Captain Yuriy Gorbach, his Keldysh crew and the MIR support team lead by Dr. Anatoly Sagalevitch. They are a highly skilled, professional team running one of the most unique and safest underwater operations in the world.

The Keldysh and MIR I and II have been used for National Geographic photo and film projects, and director James Cameron&apos;s epic motion picture Titanic. In addition to its 17 laboratories, the Keldysh features a specialized library covering underwater geology, oceanography and deep-sea exploration.

The habitation sphere (pressure hull) of the MIR submersible is 6 feet 10 inches (2.1 meters) in diameter and is specifically designed to carry three people -- in our case one expert pilot and two participants/observers. Inside the sphere it is &quot;one atmosphere,&quot; just like a room in your home. Around the inside of the sphere are many controls, instruments, and electrical circuits. At the forward end of the sphere are three viewports, each providing a forward and a partial peripheral viewing arc. There are two couches/mattresses for the two participants/observers who can lay along these with their faces close to the viewing portholes (you can also sit or stand up to stretch and relax). The pilot sits or kneels at a central control console and guides the submersible using the main central porthole. There is no vision directly to the sides or the aft end of the submersible.

text: The Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission will provide rapid-refresh microwave measurements over the tropics that can be used to observe the thermodynamics of the troposphere and precipitation structure for storm systems at the mesoscale and synoptic scale over the entire storm lifecycle. TROPICS comprises a constellation of CubeSats in three low-Earth orbital planes. Each CubeSat will host a high-performance radiometer scanning across the satellite track at 30 RPM to provide temperature profiles using seven channels near the 118.75 GHz oxygen absorption line, water vapor profiles using 3 channels near the 183 GHz water vapor absorption line, imagery in a single channel near 90 GHz for precipitation measurements, and a single channel at 206 GHz for cloud ice measurements. 

This observing system offers an unprecedented combination of horizontal and temporal resolution to measure environmental and inner-core conditions for tropical cyclones (TCs) on a nearly global scale and is a profound leap forward in the temporal resolution of several key parameters needed for detailed study of high-impact meteorological events (TCs being the primary emphasis in this proposal). TROPICS will demonstrate that a constellation approach to earth Science can provide improved resolution, configurable coverage (tropics, near global, or global), flexibility, reliability, and launch access at extremely low cost, thereby serving as a model for future missions.

Old Value=ATS 2 was launched in April 1967 and was a medium altitude,
gravity-gradient-stabilized spacecraft designed to (1) test new concepts in
spacecraft design, propulsion, and stabilization, (2) take high-quality
cloudcover pictures, (3) provide in situ measurements of the aerospace
environment, and (4) test improved communication systems.  The
cylindrically-shaped spacecraft measured 142 cm in diameter and 183 cm in
length.  The primary structural members were a corrugated thrust tube with
honeycombed bulkheads secured to each end.  Equipment components and payload
were externally mounted on the outer surface of the thrust tube as well as on a
structure that slid into the interior of the thrust tube.  Electric power was
provided by two solar arrays mounted on either end of the spacecraft&apos;s  outer
shell and by two rechargeable nickel-cadmium batteries.  Extending radially
outward from the side of the spacecraft were four 28.2 m adjustable
gravity-gradient booms.  The spacecraft telemetry system consisted of four
2.1-W transmitters (two at 136.47 MHz  and two at 137.35 MHz), in addition to a
microwave communications experiment.

This satellite carried a particle telescope, omnidirectional proton and
electron detectors, advanced vidicon camera system, and a electron magnetic
deflection spectrometer.  The second stage of the ATS 2 launch vehicle failed
to ignite resulting in an unplanned elliptical orbit.  Stresses induced by this
orbit eventually induced spacecraft tumbling.  In spite of these conditions
useful data were obtained from some of the experiments, most notably the
cosmic-ray and particle experiments and the field detection experiments.  The
satellite reentered the atmosphere on September 2, 1969.

    <skos:definition xml:lang="en">Buoys, in the oceanographic context, are platforms whose defining characteristic is that they float at a predetermined depth in the ocean.  Most often BUOYS float on the surface of the ocean.  Typically, BUOYS are divided into two categories: drifting and moored buoys.  Moored BUOYS are floats fixed in water to mark a location, warn ofdanger, or indicate a navigational channel. They can also takescientific measurements of the water including temperature andwater quality measurements.Drifting BUOYS are exclusively scientific platforms that drift along the surface of the ocean following the ocean currents and/or the surface winds depending on their configuration.  Along the trajectory, they collect oceanographic or meteorological data.Group: Platform_Details   Entry_ID: BUOYS   Group: Platform_Identification      Platform_Category: In Situ Ocean-based Platforms      Platform_Series_or_Entity: BUOYS      Short_Name: BUOYS   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The Global Position System (GPS), counterpart to the Russian Global NavigationSystem (GLONASS), is a United States Department of Defense (DoD) developed,worldwide, satellite-based radionavigation system that will be the DoD&apos;sprimary radionavigation system well into the next century. The constellationconsists of 24 operational satellites. The U.S. Air Force Space Command (AFSC)formally declared the GPS satellite constellation as having met the requirementfor Full Operational Capability (FOC) as of April 27, 1995. Requirementsinclude 24 operational satellites functioning in their assigned orbits andsuccessful testing completed for operational military functionality.GPS consists of three segments, the SPACE, CONTROL and USER Segment:1. The SPACE segment consists of 24 operational satellites in six orbitalplanes, (four satellites in each plane). The satellites operate in circular20,200 km orbits at an inclination angle of 55 degrees and with a 12-hourperiod. The position is therefore the same at the same sidereal time each day,i.e. the satellites appear four minutes earlier each day.2. The CONTROL segment consists of five Monitor Stations, three GroundAntennas, and a Master Control Station (MCS) located at Falcon AFB in Colorado.The monitor stations passively track all satellites in view, accumulatingranging data. This information is processed at the MCS to determine satelliteorbits and to update each satellite&apos;s navigation message. Updated informationis transmitted to each satellite via the Ground Antennas.3. The USER segment consists of antennas and receiver-processors thatprovide positioning, velocity and precise timing to the user.GPS provides two levels of service, Standard Positioning Service and thePrecise Positioning Service. The Standard Positioning Service (SPS) is apositioning and timing service which will be available to all GPS users on acontinuous, worldwide basis with no direct charge. The Precise PositioningService (PPS) is a highly accurate military positioning, velocity and timingservice which will be available on a continuous, worldwide basis to usersauthorized by the U.S. [Summary provided by NASA]Group: Platform_Details   Entry_ID: GPS-35   Group: Platform_Identification      Platform_Category: Navigation Platforms      Platform_Series_or_Entity: GPS (Global Positioning System)      Short_Name: GPS-35      Long_Name: Global Positioning System Satellites-35   End_Group   Group: Platform_Associated_Instruments      Short_Name: GPS      Short_Name: GPS RECEIVERS   End_Group   Group: Orbit      Orbit_Inclination: 64.8 degrees      Period: 718 minutes      Perigee: 20,195 km      Orbit_Type: MEO &gt; Semi-Synchronous &gt; Navigation   End_Group   Creation_Date: 2007-02-12   Online_Resource: http://ilrs.gsfc.nasa.gov/cgi-bin/satellite_missions/select.cgi?order=by_name&amp;sat_code=GP35&amp;sat_name=GPS-35&amp;sat_no=9305401&amp;tab_id=general   Sample_Image: http://ilrs.gsfc.nasa.gov/images/gps.gif   Group: Platform_Logistics      Launch_Date: 1993-08-30      Design_Life: 7 Years      Primary_Sponsor: U.S. Department of Defense   End_GroupEnd_Group</skos:definition>

Old Value=The Deep-ocean Assessment and Reporting of Tsunamis (DART) real-time tsunami buoy system is comprised of two parts -- the Bottom Pressure Recorder (BPR) and the accompanying surface buoy with its related electronics. The BPR resides on the ocean bottom and monitors water pressure with a resolution of approximately 1 mm seawater. Samples integrated over a 15-second time window are recorded internally by the BPR and provide the base sampling interval for all real-time transmissions. Data are transmitted from the BPR to the surface buoy via an acoustic modem which in turn transmits the data to ground systems via Iridium satellites.

Using the unique perspective available from space, NASA will observe, monitor and assess large-scale environmental processes, focusing on climate change. MTPE satellite data, complemented by aircraft and ground data, will allow humans to better understand natural environmental changes and to distinguish natural changes from human induced changes. MTPE data, which NASA will distribute to researchers worldwide, is essential to humans making informed decisions about their environment.The goal of the Total Ozone Mapping Spectrometer (TOMS) Earth Probe mission (part of NASA&apos;s Mission To Planet Earth (MTPE) Phase I program) was to continue the high-resolution global mapping of total ozone on a daily basis (begun with the Nimbus 7 SBUV/TOMS) as well as to detect global ozone trends to verify depletion predicted by atmospheric chemistry models.The TOMS-Earth Probe (TOMS-EP), the first of a series of NASA Earth Probe missions, was one of three TOMS missions which included METEOR 3/TOMS2 (launched 1991) and ADEOS/TOMS (launched 1995). The TOMS-EP carried only one instrument: the Total Ozone Mapping Spectrometer (TOMS).The TOMS-EP spacecraft was based on the TRW/DSI Eagle bus developed under the USAF STEP program. The spacecraft was three-axis stabilized so that the TOMS instrument was nadir-pointed with about 0.5 degree control and about 0.1 degree knowledge from measured altitude data. The TOMS-EP spacecraft bus was designed to accomodate all of the TOMS instrument requirements to support a two-year lifetime with a three-year lifetime goal.The EP-TOMS Home Page is located at:http://eospso.nasa.gov/missions/total-ozone-mapping-spectrometer-earth-probeGroup: Platform_Details   Entry_ID: EP-TOMS   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: EP-TOMS      Long_Name: Earth Probe-TOMS   End_Group   Group: Synonymous_Platform_Names      Short_Name: SMEX/TOMS-Earth Probe      Short_Name: Small Explorer/TOMS-Earth Probe      Short_Name: TOMS-EP96      Short_Name: TOMS-Earth Probe   End_Group   Group: Platform_Associated_Instruments      Short_Name: TOMS   End_Group   Group: Orbit      Orbit_Altitude: 740 km      Orbit_Inclination: 98.385 degrees      Period: 99.6 minutes      Perigee: 490.5 km      Apogee: 515.2 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-05-01   Online_Resource: http://eospso.nasa.gov/missions/total-ozone-mapping-spectrometer-earth-probe   Online_Resource: http://science.nasa.gov/missions/toms/   Online_Resource: http://disc.sci.gsfc.nasa.gov/acdisc/TOMS   Online_Resource: https://ozoneaq.gsfc.nasa.gov/missions   Group: Platform_Logistics      Launch_Date: 1996-07-02      Launch_Site: Vandenberg Air Force Base, USA      Design_Life: 2 years      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The DE 2 spacecraft (low-altitude mission) complemented the high-altitude mission DE 1 and was placed into an orbit with a perigee sufficiently low to permit measurements of neutral composition, temperature, and wind. The apogee was high enough to permit measurements above the interaction regions of suprathermal ions, and also plasma flow measurements at the feet of the magnetospheric field lines. The general form of the spacecraft was a short polygon 137 cm in diameter and 115 cm high. The triaxial antennas were 23 m tip-to-tip. One 6-m boom was provided for remote measurements. The spacecraft weight was 403 kg. Power was supplied by a solar cell array, which charged two 6-ampere-hour nickel-cadmium batteries. The spacecraft was three-axis stabilized with the yaw axis aligned toward the center of the earth to within 1 deg. The spin axis was normal to the orbit plane within 1 deg with a spin rate of one revolution per orbit. A single-axis scan platform was included in order to mount the low-altitude plasma instrument (81-070B-08). The platform rotated about the spin axis. A pulse code modulation telemetry data system was used that operated in real time or in a tape-recorder mode. Data were acquired on a science-problem-oriented basis, with closely coordinated operations of the various instruments, both satellites, and supportive experiments. Measurements were temporarily stored on tape recorders before transmission at an 8:1 playback-to-record ratio. Since commands were also stored in a command memory unit, spacecraft operations were not real time.

    <skos:prefLabel xml:lang="en">FAST</skos:prefLabel>
    <skos:definition xml:lang="en">The Fast Auroral SnapshoT Explorer (FAST), the second mission in NASA&apos;s SmallExplorer Satellite Program (SMEX), is a satellite designed to study Earth&apos;saurora. This highly successful spacecraft has helped scientists answerfundamental questions about the causes and makeup of the aurora. FAST was launched on August 21, 1996 from a Pegasus rocket into a highlyelliptical orbit. It crosses Earth&apos;s auroral zones (donut shaped regionscentered on the poles) four times each orbit, and only collects high-resolutiondata (&apos;snapshots&apos;) while in those zones. It ventures high into the chargedparticle environment of the aurora to measure the electric and magnetic fields,plasma waves, energetic electrons and ions, ion mass composition, and thermalplasma density and temperature.The FAST instrument set consists of sixteen electrostatic analyzers, fourelectric field langmuir probes suspended on 30 m wire booms, two electric fieldlangmuir probes on 3 m extendible booms, searchcoil and fluxgate magnetometersand a time-of-flight mass spectrometer. The science investigation makesextremely temporal and spatial resolution measurements of the auroral plasma atapogee altitude. The instrument hardware consists of the sensor assemblies andan instrument data processor. The instrument electronics include a 32-bit dataprocessing unit that performs the science data processing and recording in aone gigabit, solid-state memory. The stored data are transferred to the groundat one of three selectable high data rates of 900 Kbps, 1.5 Mbps or 2.25 Mbps.The instruments weigh 51 kg; the total observatory mass is 191 kg. The FASTmission is in a 351 x 4175 km orbit with an 83? inclination.The FAST observatory is a 12 rpm, spin-stabilized spacecraft with its spin axisoriented parallel to the orbit axis. Spin rate and spin-axis orientation aremaintained by two magnetic torquer coils, one spinning Sun sensor, one horizoncrossing indicator and a spacecraft magnetometer. The Attitude Control System(ACS) provides closed-loop spin-rate control. Spin-axis precession is performedopen loop and is closed via ground commands. After computation on the ground,attitude knowledge is accurate to within one degree.The body-mounted solar array contains 5.6 m2 of solar cells that can distribute52 W of orbit average power to the spacecraft and instruments. The orbitaverage power consumption of the spacecraft hardware is 33 W. The instrumentsconsume 19 W orbit average power, 39 W when operating. Instruments arefrequently powered off in order to maintain a positive energy balance.The data system for the FAST mission consists of dual 8085, 8-bit spacecraftcomputers. The spacecraft computers perform health and safety functions, powerdistribution, data encoding/decoding and launch vehicle interface. Amulti-element micropatch antenna mounted on a boom above the spacecraftsupports ground communications. Commands are uplinked at 2 Kbps. Health andsafety data is telemetered to the ground at 4 Kbps. A Transportable OrbitalTracking Station (TOTS) was placed in Alaska to collect real-time sciencetelemetry while the spacecraft is passing through the northern aurora. TOTS ishighly automated and portable; it has an 8 m antenna with 200 W of uplink powerand can be packed for shipment in three ISO containers. The FAST instruments consist of:Electric Field Experiment: The electric field experiment is composed of threeorthogonal boom pairs. Spherical sensors deployed on radial wire and axialstacer booms will provide information on the plasma density and electrontemperature.Magnetic Field Experiment: The magnetic field experiment consists of twomagnetometers mounted 180? apart on deployable graphite epoxy booms. The searchcoil magnetometer uses a three-axis sensor system to provide magnetic fielddata over the frequency range of 10 Hz to 2.5 kHz. The flux gate magnetometeris a three-axis system using high, stable, low noise, ring core sensors toprovide magnetic field information for DC to 100 Hz.Time-of-Flight Energy Angle Mass Spectrograph (TEAMS): The TEAMS instrument isa high sensitivity, mass-resolving spectrometer that measures fullthree-dimension distribution functions of the major ion species with one spinof the spacecraft. The TEAMS experiment covers the core of all plasmadistributions of importance in the auroral region.Electrostatic Analyzers (ESA): Sixteen ESAs configured in four stacks will beused for both electron and ion measurements. The four stacks are placed aroundthe spacecraft such that the entire package is provided a full 360? field ofview. The ESAs can provide a 64-step energy sweep, covering approximately 3 eVto 30 KeV up to 16 times per second.For more information, see:http://sprg.ssl.berkeley.edu/fast/Group: Platform_Details   Entry_ID: FAST   Group: Platform_Identification      Platform_Category: Solar/Space Observation Satellites      Short_Name: FAST      Long_Name: Fast Auroral Snapshot Explorer   End_Group   Group: Synonymous_Platform_Names      Short_Name: Explorer 70      Short_Name: SMEX/FAST      Short_Name: Small Explorer/FAST      Short_Name: 24285      Short_Name: 1996-049A   End_Group   Group: Platform_Associated_Instruments      Short_Name: MFS/FAST      Short_Name: EFS/FAST      Short_Name: ESA/FAST      Short_Name: TEAMS   End_Group   Group: Orbit      Orbit_Inclination: 83 degrees      Period: 133 m      Perigee: 350 km      Apogee: 4175 km      Orbit_Type: HEO &gt; Highly Elliptical Orbit   End_Group   Online_Resource: http://sprg.ssl.berkeley.edu/fast/intro.html   Sample_Image: http://sprg.ssl.berkeley.edu/fast/graphics/fast.gif   Group: Platform_Logistics      Launch_Date: 1996-08-21      Launch_Site: Vandenberg Air Force Base, USA      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">Spacecraft Brief Description  The  objectives  of  the  OSO  satellite  series were to perform solar  physics experiments above the atmosphere during a complete solar cycle  and  to map the entire celestial sphere for direction and intensity of  UV  light and X-ray and gamma radiation.  The OSO 7 platform consisted  of  a  sail  section, which pointed two experiments continually toward  the  sun,  and a wheel section, which spun about an axis perpendicular  to  the  pointing  direction of the sail and carried four experiments.  Attitude  adjustment was performed by gas jets and a magnetic torquing  coil.   A  pointing  control permitted the pointed experiments to scan  the  region  of  the solar disk in a 60- by 60-arc-min raster pattern.  In addition, the pointed section could be commanded to select and scan  any  7.5-  by  5-arc-min  region  near  the  solar  disk.   Data  were  simultaneously  recorded  on tape and transmitted by PCM/PM telemetry.  A  command  system  provided  for  at least 155 ground-based commands.  Only real-time data have been received since May 1973, when the second  tape recorder failed.  The spacecraft reentered the earth&apos;s atmosphere  July 9, 1974.Auxiliary Information  Launch Date and Time : 1971-09-29 09:50:00  Epoch Date and Time :  1971-09-30  Orbit Type :  Geocentric  Apogee(km) :     572.

text: Moored buoys are the weather sentinels of the sea. They are deployed in the coastal and offshore waters from the western Atlantic to the Pacific Ocean around Hawaii, and from the Bering Sea to the South Pacific. NDBC&apos;s moored buoys measure and transmit barometric pressure; wind direction, speed, and gust; air and sea temperature; and wave energy spectra from which significant wave height, dominant wave period, and average wave period are derived. Even the direction of wave propagation is measured on many moored buoys.

NDBC&apos;s fleet of moored buoys includes 6 types: 3-m, 10-m, and 12-m discus hulls; 6-m boat-shaped (NOMAD) hulls; and the newest, the Coastal Buoy and the Coastal Oceanographic Line-of-Sight (COLOS) buoy. The choice of hull type used usually depends on its intended deployment location and measurement requirements. To assure optimum performance, a specific mooring design is produced based on hull type, location, and water depth. For example, a smaller buoy in shallow coastal waters may be moored using an all-chain mooring. On the other hand, a large discus buoy deployed in the deep ocean may require a combination of chain, nylon, and buoyant polypropylene materials designed for many years of service. Some deep ocean moorings have operated without failure for over 10 years.

In addition to their use in operational forecasting, warnings, and atmospheric models, moored buoy data are used for scientific and research programs, emergency response to chemical spills, legal proceedings, and engineering design.

    <skos:prefLabel xml:lang="en">MONITOR-E</skos:prefLabel>
    <skos:definition xml:lang="en">Monitor-E is a Russian Earth observation mission of KhSC (Khrunichev Space Center) on a small-class generic satellite series. The spacecraft was also designed and developed by KhSC of Moscow.The Monitor-E mission represents the first operational use of the newly developed modular and multipurpose Yakhta platform, intended for use in various remote sensing, communications, and space research applications.Spacecraft:The spacecraft is 3-axis stabilized using the generic Yakhta platform with a launch mass of 750 kg. The attitude pointing accuracy is 0.1º, the attitude rate control accuracy is 0.001º/s (angular drift). Power of 1200 W (max at EOL) is provided by two solar panels. The spacecraft features a cross-track pointing capability of ±30º from nadir by using a flywheel system, thereby providing a FOR (Field of Regard) for observation coverage considerably beyond that of the nominal swath width. This new S/C agility is provided by the introduction of a CMG (Control Moment Gyro) subsystem, an actuator within the ADCS (Attitude Determination and Control Subsystem), developed by Russian industry. KhSC refers to the ADCS as ICS (Integrated Control System). The S/C system design life is 5 years.Note: The Monitor-E spacecraft is of Monitor-E heritage (same name of previous and current missions) which was launched on June 30, 2003 from Plesetsk on a Rockot KS vehicle. On this flight, Monitor-E functioned as a mock-up (or prototype) spacecraft of KhSC with a mass of 700 kg. The spacecraft Monitor-E remained attached to the upper stage of the launch vehicle, it was used for demonstration purposes. RF communications: The payload data are being received in X-band by ground stations of federal, regional, and local levels in Russia. An effort is being made to acquire the data in near real-time in support of fast reaction response applications.Orbit: Sun-synchronous near-circular orbit: mean altitude = 540 km, inclination = 97.5º.Launch: A launch of Monitor-E took place on Aug. 26, 2005 on a Rockot Breeze-KM launch vehicle of Eurockot Launch Services from the Plesetsk Cosmodrome, Russia.Mission status: Monitor-E is operational as of 2007. So far, the spacecraft has collected imagery of more than 80 million km2.• After launch and orbit insertion, the spacecraft experienced initial attitude control problems (flight controllers lost contact with the satellite). However, the flight controllers have regained control of Monitor-E, all systems are operating nominally and the spacecraft is in the commissioning phase as of early November 2005 (the checkout phase is estimated to last for up to 6 months to test the new components of the platform and the payload - and to conduct various operational experiments).• In Sept. 2006, Monitor-E experienced a malfunction of its ADCS (Attitude Determination and Control Subsystem). After analysis of the problem nature, a software work-around procedure was developed and successfully installed onboard.Information obtained from http://www.eoportal.org/Group: Platform_Details   Entry_ID: MONITOR-E   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: MONITOR-E-1   End_Group   Group: Synonymous_Platform_Names      Short_Name: Monitor Experimental   End_Group   Group: Platform_Associated_Instruments      Short_Name: CAMERAS      Short_Name: MS   End_Group   Group: Orbit      Orbit_Altitude: 540 km      Orbit_Inclination: 97.5 degrees      Period: 95.2 minutes      Perigee: 532.0 km      Apogee: 539.2 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2008-07-10   Online_Resource: http://directory.eoportal.org/get_announce.php?an_id=11116   Group: Platform_Logistics      Launch_Date: 2005-08-26      Launch_Site: Plesetsk Cosmodrome, Russia      Design_Life: 5 years      Primary_Sponsor: Khrunichev Space Center, Russia   End_GroupEnd_Group</skos:definition>

text: Space-based platforms include the space station as well as both low-level (700 to 1500 km) and high-level (~ 36,000 km) satellites. These types of platforms can acquire large areas of data in a short amount of time, which can be used to monitor Earth resources, atmospheric dynamics, and other applications.

    <skos:definition xml:lang="en">Endeavour, the newest addition to the four-orbiter fleet, is named after the first ship commanded by James Cook, the 18th century British explorer, navigator and astronomer. For the first time, a national competition involving students in elementary and secondary schools produced the name of the new orbiter; it was announced by President George Bush in 1989. The Space Shuttle orbiter Endeavour was delivered to Kennedy Space Center in May 1991, and flew its first mission, highlighted by the dramatic rescue of a stranded communications satellite, a year later in May 1992.Endeavour features new hardware designed to improve and expand orbiter capabilities. Most of this equipment was later incorporated into the other three orbiters during out-of-service major inspection and modification programs. Endeavour&apos;s upgrades include:-A 40-foot diameter drag chute that is expected to reduce the orbiter&apos;s rollout distance by 1,000 to 2,000 feet.-The plumbing and electrical connections needed for Extended Duration Orbiter (EDO) modifications to allow up to 28-day missions.-Updated avionics systems that include advanced general purpose computers, improved inertial measurement units and tactical air navigation systems, enhanced master events controllers and multiplexer-demultiplexers, a solid-state star tracker and improved nose wheel steering mechanisms.-An improved version of the Auxiliary Power Units (APU&apos;s) that provide power to operate the Shuttle&apos;s hydraulic systems.[Summary provided by NASA]Group: Platform_Details   Entry_ID: OV-105   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: OV-105      Long_Name: Endeavour Space Shuttle   End_Group   Group: Synonymous_Platform_Names      Short_Name: Endeavour   End_Group   Creation_Date: 2008-01-25   Online_Resource: http://science.ksc.nasa.gov/shuttle/resources/orbiters/endeavour.html   Sample_Image: http://www-pao.ksc.nasa.gov/kscpao/images/medium/02pd0590-m.jpg   Group: Platform_Logistics      Launch_Date: 1992-05-07      Launch_Site: Cape Canaveral/Kennedy Space Center, USA      Primary_Sponsor: USA/NASA   End_GroupEnd_Group</skos:definition>

Old Value=ATS 1 was launched in December 1966 and was the first in a series of
geostationary satellites to be used in a research mode, while also
demonstrating communications satellite technology.  It was designed for the
purpose of (1) testing new concepts in spacecraft design, propulsion, and
stabilization, (2) collecting high-quality cloudcover pictures and relaying
processed meteorological data via an earth-synchronous satellite, (3) providing
in situ measurements of the aerospace environment, and (4) testing improved
communication systems.  The spin-stabilized spacecraft was cylindrically shaped
and measured 135 cm long and 142 cm in diameter.  The primary structural
members were a honeycombed equipment shelf and thrust tube.  Support rods
extended radially outward from the thrust tube.  Solar panels were affixed to
the support rods and formed the outer walls of the spacecraft.  In addition to
solar panels, the spacecraft was equipped with two rechargeable nickel-cadmium
batteries to provide electrical power.  Equipment components and payload were
mounted in the annular space between the thrust tube and solar panels.
This satellite carried a spin scan cloudcover camera, particle telescope,
biaxal fluxgate magnetometer, suprathermal ion detector, omnidirectional
spectrometer, weather facsimile data relay system, and VHF, telemetry and
command antennas.  Spacecraft  guidance  and  orbital corrections were
accomplished by a 2.3 kg hydrogen peroxide and hydrazine thrusters, which were
activated by ground command.  The satellite was initially placed at 151.16
degrees West over the Pacific Ocean in a geosynchronous orbit.  In general,
most of the experiments were successful.  Data coverage was nominal until about
1970, after which limited real-time data acquisition was carried out by NOAA
until the May 1974 launch of SMS 1.  Limited ATS 1 data acquisition was started
by NASA at about that time for ATS 1 - ATS 6 correlative  studies.  The
spacecraft served as a communications satellite for a number of state, federal,
and public organizations.  It continued to operate at its final longitude of
164 degress East until September 1983, when the spacecraft was moved out of the
geostationary orbit.

New Value=The ATS 1 spacecraft shows its Syncom heritage, but at 351.5 kg (775 lb) on-orbit, with a length of 1.5 m (54 inches), was a larger and a much more capable satellite than its predecessor. In addition to a C-band transponder, ATS-1 carried a VHF experiment for communications with aircraft, ships, meteorological remote terminals, and to evaluate VHF satellite navigation. It used an eight-element phased array antenna with a 5 Watt transmitter for each element. The spacecraft was spin stabilized and had solar cells mounted around the barrel shaped body to provide 175 Watts of electrical power.</skos:changeNote>

    <skos:definition xml:lang="en">CartoSat-2A is a follow-up optical imaging mission of CartoSat-2 (launch Jan. 10, 2007), representing India&apos;s first dedicated military satellite (funding by the Ministry of Defense of the Government of India). The overall objective is to provide scene-specific spot imagery in high resolution to the Indian Armed Forces - which is in the process of establishing an Aerospace Command.The spacecraft and its payload, built by ISRO, is practically an identical copy of the CartoSat-2 spacecraft of ISRO. It features a lightweight and compact bus structure using the BMU (Bus Management Unit) for integrated bus functions (of the AOCS, TT&amp;C, etc.). The spacecraft is 3-axis stabilized using high torque reaction wheels, magnetic torquers, and hydrazine thrusters. Attitude sensing is provided by a high performance star sensor and by an improved IRU (Inertial Reference Unit). The satellite is very agile providing a body-pointing capability in along-track and cross-track of up to ±45º (this supports a revisit capability of certain target regions within 4 days). Also use of the SPS (Satellite Positioning System), an 8-channel GPS receiver (C/A code) on-board for the provision of instantaneous state vectors (state vector using pseudo range and range rate measurements) for the spacecraft.The fixed solar arrays (triple-junction solar cells) provide a power of 900 W when pointed toward the sun; two NiCd batteries of 18 Ah capacity are being used for ecliptic phase bridging.CartoSat-2A has a launch mass of 690 kg and a design life of 5 years. Launch: The launch of CartoSat-2A took place on April 28, 2008 on a PSLV launcher. The launch was conducted from the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota space station in southern India. Next to the primary payload of CartoSat-2A, the PSLV-C9 vehicle successfully launched the IMS-1 (Indian Microsatellite-1) of 83 kg and eight nanosatellites for international customers.Sensor complement:PAN Camera (Panchromatic Camera). The objective is to provide imagery for cartographic applications. The optical system is designed with two mirror Ritchey-Chretien on-axis obscured reflective telescope system with a concave hyperboloidal primary mirror and convex hyperboloid secondary mirrors and the field correcting relay optics. The mirrors are made of special Zerodur glass and are light-weighted to about 60% as in CartoSat-1 series. The mirrors are mounted inside the telescope cylinder made of CFRP with special MFDs (Mirror Fixation Devices) and the whole telescope assembly is mounted to the spacecraft structure through a special suspension arrangement. The optical system is designed to provide &lt; 1 m resolution across track. The along track GSD of &lt; 1 m is achieved by apparent velocity reduction by a factor of 2.5.The spacecraft can be suitably biased to provide various modes of imaging:1) Continuous strip monoscopic mode2) Spot scene imaging (strips on either side of the ground track can be imaged)3) Paint brush mode of imaging. This mode is used to increase the total swath. Both roll tilt and pitch tilt is employed.The PAN Camera is a nadir-pointing pushbroom CCD instrument (detector line array of 12, 288 pixels), observing in the visible spectral range of 0.5-0.85 µm with a GSD (Ground Sample Distance) of &lt; 1 m, and a swath width of 9.6 km at nadir. The spacecraft is being monitored and controlled from the ISRO mission control center in Bangalore, India using the ISTRAC network of stations at Bangalore, Lucknow, Mauritius, Bearslake in Russia, Biak in Indonesia and Svalbard in Norway.Group: Platform_Details   Entry_ID: CARTOSAT-2A   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: CARTOSAT-2A   End_Group   Group: Platform_Associated_Instruments      Short_Name: PAN   End_Group   Group: Orbit      Orbit_Altitude: 635 km      Orbit_Inclination: 97.94 degrees       Period: 97.4 minutes      Repeat_Cycle: 4 days      Perigee: 628.7 km      Apogee: 653.2 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2008-06-27   Online_Resource: http://directory.eoportal.org/get_announce.php?an_id=10000443   Online_Resource: http://www.isro.org/pslv-c9/cartosat2a.htm   Sample_Image: http://directory.eoportal.org/presentations/7336/CartoSat2A_Auto2.jpeg   Group: Platform_Logistics      Launch_Date: 2008-04-28      Launch_Site: Sriharikota Island, India      Design_Life: 5 YEARS      Primary_Sponsor: Ministry of Defense of the Government of India   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The objectives of the OSO satellite series were to perform solar physicsexperiments above the atmosphere during a complete solar cycle and to map thecelestial sphere for direction and intensity of UV light, X-rays, and gammaradiation. The OSO 1 was the first satellite to have pointed instruments andonboard tape recorders for data storage.  The OSO 1 platform consisted of asail section, which pointed two experiments continuously toward the sun,supplying power to the experiments from the solar batteries and rechargeablechemical batteries; and a wheel section, which spun about an axis perpendicularto the pointing direction of the sail and carried seven experiments. Attitudeadjustment was performed by gas jets. Data were simultaneously recorded on tapeand transmitted by FM telemetry. A command system provided for 10 ground-basedcommands. The spacecraft performed normally until the second onboard taperecorder failed May 15, 1962. The spacecraft provided real-time data until May1964, when the power cells failed.General Information:Designation: 00255 / 62006ALaunch date: 7 Mar 1962Country of origin: United StatesMission: Scientific (Sun observation)Perigee/Apogee:  522/553 kmInclination:  32.8°Period:  95.3 minLaunch vehicle:  Thor Delta #8End of Life:Out of service  Apr 1963Decay  8 Oct 1981Additional information available at&apos;http://heasarc.gsfc.nasa.gov/docs/heasarc/missions/oso1.html&apos;[Summary provided by NASA and The Satellite Encyclopedia]Group: Platform_Details   Entry_ID: OSO-1   Group: Platform_Identification      Platform_Category: Solar/Space Observation Satellites      Platform_Series_or_Entity: OSO (Orbiting Solar Observatory)      Short_Name: OSO-1      Long_Name: Orbiting Solar Observatory-1   End_Group   Group: Synonymous_Platform_Names      Short_Name: OSO-1   End_Group   Group: Orbit      Orbit_Inclination: 32.8 degrees      Period: 95.3 min      Perigee: 522 km      Apogee: 553 km   End_Group   Creation_Date: 2007-12-14   Online_Resource: http://heasarc.gsfc.nasa.gov/docs/heasarc/missions/oso1.html   Sample_Image: http://www.nasm.si.edu/spacecraft/images/SS-Astro/A19820270000d.jpg   Group: Platform_Logistics      Launch_Date: 1962-03-07      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

text: Complementing the geostationary satellites are polar-orbiting satellites known as POES, S-NPP, and JPSS-1 (now NOAA-20). NOAA-20 is the first of the JPSS Series. Polar orbiting satellites constantly circle the Earth in an almost north-south orbit, passing close to both poles.

The POES satellite system offers the advantage of daily global coverage, by making nearly polar orbits 14 times per day approximately 520 miles above the surface of the Earth. The Earth&apos;s rotation allows the satellite to see a different view with each orbit, and each satellite provides two complete views of weather around the world each day. NOAA partners with the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) to constantly operate two polar-orbiting satellites – one POES and one European polar-orbiting satellite called Metop.

The POES instruments include the Advanced Very High Resolution Radiometer (AVHRR) instrument and the Advanced TIROS Operational Vertical Sounder (ATOVS) suite. The EUMETSAT-provided Microwave Humidity Sounder (MHS) instrument completes the ATOVS suite. The AVHRR/ATOVS provides visible, infrared, and microwave data which is used for a variety of applications such as cloud and precipitation monitoring, determination of surface properties, and humidity profiles.

Data from the POES series supports a broad range of environmental monitoring applications including weather analysis and forecasting, climate research and prediction, global sea surface temperature measurements, atmospheric soundings of temperature and humidity, ocean dynamics research, volcanic eruption monitoring, forest fire detection, global vegetation analysis, search and rescue, and many other applications.

The orbits are circular, with an altitude between 830 (morning orbit) and 870 (afternoon orbit) km, and are sun synchronous. One satellite crosses the equator at 7:30 a.m. local time, the other at 1:40 p.m. local time. The circular orbit permits uniform data acquisition by the satellite and efficient control of the satellite by the NOAA Command and Data Acquisition (CDA) stations located near Fairbanks, Alaska and Wallops Island, Virginia. Operating as pair, these satellites ensure that data for any region of the Earth are no more than six hours old.

A suite of instruments is able to measure many parameters of the Earth&apos;s atmosphere, its surface, cloud cover, incoming solar protons, positive ions, electron-flux density, and the energy spectrum at the satellite altitude. As a part of the mission, the satellites can receive, process and retransmit data from Search and Rescue beacon transmitters, and automatic data collection platforms on land, ocean buoys, or aboard free-floating balloons.

Old Value=The Autonomous Temperature Line Acquisition System was initiated by PMEL&apos;s Engineering Development Division (EDD) in 1984. The standard ATLAS mooring had a design lifetime of one year, and the system proved to be robust and reliable. Over 500 Standard ATLAS moorings were deployed between 1984 and 2001. The final standard ATLAS was recovered in November 2001 and NextGeneration ATLAS moorings are now used exclusively in the TAO array.

Standard ATLAS moorings measured surface winds, air temperature, relative humidity, sea surface temperature, and ten subsurface temperatures from a 500 m long thermistor cable. Daily-mean data were telemetered to shore in near real-time via NOAA&apos;s polar-oribiting satellites and Service Argos. A small subset of hourly values (2-3 per day) coinciding with satellite passes were also transmitted in real time. Hourly values of surface data were internally recorded and available after mooring recovery.

New Value=The Autonomous Temperature Line Acquisition System was initiated by PMEL&apos;s Engineering Development Division (EDD) in 1984. The standard ATLAS mooring had a design lifetime of one year, and the system proved to be robust and reliable. Over 500 Standard ATLAS moorings were deployed between 1984 and 2001. The final standard ATLAS was recovered in November 2001 and NextGeneration ATLAS moorings are now used exclusively in the TAO array.

Standard ATLAS moorings measured surface winds, air temperature, relative humidity, sea surface temperature, and ten subsurface temperatures from a 500 m long thermistor cable. Daily-mean data were telemetered to shore in near real-time via NOAA&apos;s polar-oribiting satellites and Service Argos. A small subset of hourly values (2-3 per day) coinciding with satellite passes were also transmitted in real time. Hourly values of surface data were internally recorded and available after mooring recovery.</skos:changeNote>

    <skos:definition xml:lang="en">The Communications/Navigation Outage Forecasting System (C/NOFS) is a prototype operational system designed to monitor and forecast ionospheric scintillation in real-time and on a global scale. Timely location of scintillation outage regions would enable the warfighter to modify mission plans and prevent potential mission failures by optimizing and tailoring communications routes, paths, and/or priorities and effectively use satellite communications, navigation, and surveillance assets. It will include three critical elements. The first is a space-borne sensor system consisting of seven proven sensors to provide data for global, real-time specification, and 4 hour forecast capability. The second is a series of regional ground networks that augment the space based sensors for real time, high resolution coverage in theater. The third is a forecasting/decision aid software package that produces tailored space environmental forecasts and warnings in the form of outage maps for the warfighter.Information provided by http://www.fas.org/spp/military/program/nssrm/initiatives/cnofs.htmGroup: Platform_Details   Entry_ID: C/NOFS   Group: Platform_Identification      Platform_Category: Solar/Space Observation Satellites      Short_Name: C/NOFS      Long_Name: Communication and Navigation Outage Forecast System   End_Group   Group: Synonymous_Platform_Names      Short_Name: C/NOFS   End_Group   Group: Platform_Associated_Instruments      Short_Name: GPS   End_Group   Group: Orbit      Orbit_Type: MEO &gt; Semi-Synchronous &gt; Navigation   End_Group   Creation_Date: 2007-08-13   Online_Resource: http://www.fas.org/spp/military/program/nssrm/initiatives/cnofs.htmEnd_Group</skos:definition>

Old Value=The Japan Marine Science and Technology Center (JAMSTEC) is developing a surface moored buoy network named TRITON (TRIangle Trans-Ocean Buoy Network) for observing oceanic and atmospheric variability in the Pacific Ocean and its adjacent seas in cooperation interested Japanese and foreign agencies and institutions. The principal scientific objective is to understand variations of ocean circulation and heat/salt transports with emphasis on ENSO, the Asian monsoon, and decadal scale variability that influences world wide climate change. In its first phase, the TRITON array will be established mainly in the western tropical pacific Ocean, and harmonized with TAO array which are presently maintained by Pacific Marine Environmental Laboratory (PMEL), NOAA. The fundamental functions of TRITON are (1) basin scale ENSO monitoring, and (2) measurements of heat, freshwater, momentum fluxes for improving modeling capability.

The TRITON (Triangle Trans-Ocean buoy network) is a series of buoys for measuring surface meteorology and upper ocean.

The buoys will be deployed by JAMSTEC in collaboration with many countries in and around the Pacific Ocean as part of international climate research programs.

The buoys measure wind, air temperature, humidity, precipitation, short wave radiation, water temperature, salinity and current. The water temperature and will be measured down to 750m depth.

The data will be transmitted via satellite near real time and provided to researchers in the world.

Each CubeSat will host a high-performance radiometer scanning across the satellite track at 30 RPM to provide temperature profiles using seven channels near the 118.75 GHz oxygen absorption line, water vapor profiles using 3 channels near the 183 GHz water vapor absorption line, imagery in a single channel near 90 GHz for precipitation measurements, and a single channel at 206 GHz for cloud ice measurements.

This observing system offers an unprecedented combination of horizontal and temporal resolution to measure environmental and inner-core conditions for tropical cyclones (TCs) on a nearly global scale and is a profound leap forward in the temporal resolution of several key parameters needed for detailed study of high-impact meteorological events (TCs being the primary emphasis in this proposal). TROPICS will demonstrate that a constellation approach to earth Science can provide improved resolution, configurable coverage (tropics, near global, or global), flexibility, reliability, and launch access at extremely low cost, thereby serving as a model for future missions.

AIMP-1 was a spin-stabilized spacecraft with spin axis parallel to the ecliptic plane, and spin period varying between 2.2 sec and 3.6 sec.  The spacecraft was instrumented for studies of interplanetary plasma, energetic charged particles [electrons, protons and helium ions (alpha particles)], magnetic fields, and solar X-rays at lunar distances. Unfortunately, the spacecraft failed to achieve lunar orbit but did achieve major mission objectives.  The initial AIMP-1 apogee occurred at about 16:00 hour local time.  Over the first 3-year period, perigee varied between 6 earth radii and 44 earth radii and apogee varied between 70 earth radii and 135 earth radii.  The inclination with respect to the equatorial plane of the earth varied between 7 degrees and 60 degrees.

text: Geostationary satellites circle the Earth in geosynchronous orbit, which means they orbit the Earth’s equatorial plane at a speed matching the Earth’s rotation. This allows them to stay in a fixed position in the sky, remaining stationary with respect to a point on the ground. GOES satellites continually view the Western Hemisphere from approximately 22,300 miles above Earth.

Since 1975, NOAA&apos;s Geostationary Operational Environmental Satellites (GOES) have provided continuous imagery and data on atmospheric conditions and solar activity (space weather). They have even aided in search and rescue of people in distress. GOES data products have led to more accurate and timely weather forecasts and better understanding of long-term climate conditions. The National Aeronautics and Space Administration (NASA) builds and launches the GOES, and the National Oceanic and Atmospheric Administration (NOAA) operates them. In October 2015, NOAA celebrated the 40th anniversary of the launch of the first GOES satellite.

GOES satellites are designated with a letter prior to launch and renamed with a number once achieving geostationary orbit. The GOES-N series consists of GOES-13, GOES-14, and GOES-15.

    <skos:definition xml:lang="en">Geostationary satellites circle the Earth in geosynchronous orbit, which means they orbit the Earth’s equatorial plane at a speed matching the Earth’s rotation. This allows them to stay in a fixed position in the sky, remaining stationary with respect to a point on the ground. GOES satellites continually view the Western Hemisphere from approximately 22,300 miles above Earth.Since 1975, NOAA&apos;s Geostationary Operational Environmental Satellites (GOES) have provided continuous imagery and data on atmospheric conditions and solar activity (space weather). They have even aided in search and rescue of people in distress. GOES data products have led to more accurate and timely weather forecasts and better understanding of long-term climate conditions. The National Aeronautics and Space Administration (NASA) builds and launches the GOES, and the National Oceanic and Atmospheric Administration (NOAA) operates them. In October 2015, NOAA celebrated the 40th anniversary of the launch of the first GOES satellite.GOES satellites are designated with a letter prior to launch and renamed with a number once achieving geostationary orbit. The GOES-N series consists of GOES-13, GOES-14, and GOES-15.</skos:definition>

Old Value=ATS 4 was launched in August 1968 and was a gravity-gradient-stabilized
spacecraft designed to (1) test new concepts in spacecraft design, propulsion,
and stabilization, (2) take high-quality cloud cover pictures, (3) provide in
situ measurements of the aerospace environment, and (4) test improved
communication systems while in earth-synchronous orbit.  The
cylindrically-shaped spacecraft measured 142 cm in diameter and 183 cm in
length.  The primary structural members were a corrugated thrust tube with
honeycombed bulkheads secured to each end.  Equipment components and payload
were externally mounted on the outer surface of the thrust tube as well as on a
structure that slid into the interior of the thrust  tube.  Electric power was
provided by two solar arrays mounted on either end of the spacecraft&apos;s outer
shell and by two rechargeable nickel-cadmium batteries.  Extending radially
outward from the side of the spacecraft were four 28.2 m adjustable
gravity-gradient booms.   The spacecraft telemetry system consisted of four
2.1-W transmitters, (two at 136.47 MHz and two at 137.35 MHz), in addition to a
microwave  communications  experiment.

This satellite featured an image orthicon (day/night) camera for the purpose of
determining the feasibility of simultaneous day/night imaging of cloud cover
patterns from an earth-synchronous spacecraft.  The second stage of the launch
vehicle failed to to ignite, and the planned synchronous orbit was not
achieved.  The spacecraft and its Centaur booster rocket were left attached
together in a parking orbit. In spite of the anomalistic attitude, some of the
experiments did perform successfully before the satellite and its attached
rocket booster reentered the earth&apos;s atmosphere on October 17, 1968.  The
primary objective of inserting a gravity-gradient-stabilized spacecraft into a
geosynchronous orbit was not accomplished.

New Value=The ATS-4 was launched to evaluate gravity-gradient stabilization and new imaging techniques for meteorological data retrieval. The spacecraft was deactivated after 61 minutes when the Centaur rocket failed to ignite. The satellite&apos;s orbit was too low and the resulting atmospheric drag caused it to re-enter the Earth&apos;s atmosphere.
Although the spacecraft was not stable, due to this low orbit, NASA engineers successfully turned on several of the experiments to collect as much information as possible before the satellite broke apart on October 17, 1968.</skos:changeNote>

The attitude control system is used to keep the spin axis aligned with the orbit normal and to maintain the spin rate. Spin axis control is achieved by a chargeable permanent magnet system which is operated upon command and reacts with the earth&apos;s field to produce precession of several degrees per minute. With this system the spin axis was kept within 10 degrees of the orbit normal for several weeks at a time, although larger deviations have been tolerated. The spin rate was observed to decay at 0.05 rpm per day. Periodic use of the spin rate control system has compensated for spin decay. This system is analogous to a DC motor in which the entire satellite is the armature.Group: Platform_Details   Entry_ID: EXPLORER-31 (DME-A)   Group: Platform_Identification      Platform_Category: Solar/Space Observation Satellites      Platform_Series_or_Entity: EXPLORER      Short_Name: EXPLORER-31 (DME-A)   End_Group   Group: Synonymous_Platform_Names      Short_Name: Explorer-A      Short_Name: Explorer 31      Short_Name: 01806   End_Group   Group: Platform_Associated_Instruments      Short_Name: SPHERICAL MASS SPECTROMETER      Short_Name: ELECTROSTATIC ANALYZERS      Short_Name: ENERGETIC ELECTRON CURRENT MONITOR      Short_Name: ELECTRON TEMPERATURE PROBE      Short_Name: MAGNETIC ION-MASS SPECTROMETER   End_Group   Group: Orbit      Orbit_Inclination: 79.80 degrees      Period: 119.70 min      Perigee: 505 km      Apogee: 2833 km   End_Group   Creation_Date: 2007-12-14   Online_Resource: http://stinet.dtic.mil/oai/oai?verb=getRecord&amp;metadataPrefix=html&amp;identifier=AD0656730   Sample_Image: http://www.daviddarling.info/images/DME.jpg   Group: Platform_Logistics      Launch_Date: 1965-11-29      Launch_Site: Vandenberg Air Force Base, USA      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

Old Value=ATS 3 was launched in November 1967 and was one of a series of spacecraft
designed to demonstrate the utility and feasibility of a variety of
technological and scientific activities that could be carried out by an
earth-synchronous spacecraft.  Of the 11 experiments on board, 8 were
technological engineering experiments concerned with navigation,
communications, and spacecraft operation equipment; 2 were photographic imaging
experiments that produced near real-time daylight pictures of the
earth-atmosphere system; and the remaining experiment was an ionospheric
beacon.  The spin-stabilized spacecraft was cylindrically shaped and measured
180 cm in length and 142 cm in diameter.  The primary structural members were
a honeycombed equipment shelf and thrust tube.  Support rods extended radially
outward from the thrust tube and were affixed to solar panels which formed the
outer walls of the spacecraft.  Equipment components and payload were mounted
in the annular space between the thrust tube and solar panels.  In addition to
solar panels, the spacecraft was equipped with two rechargeable nickel-cadmium
batteries to provide electrical power.

This satellite supported an image dissector camera, multicolor spin scan
cloud cover camera, weather facsimile data relay system, omega position and
location equipment designed to demonstrate the feasibility of using the NAVY&apos;s
Omega Navigation System, and VHF, telemetry, and command antennas.  Spacecraft
guidance and orbital corrections were accomplished by 2.3 kg hydrogen peroxide
and hydrazine thrusters, which were activated by ground command.  Initially
placed at 48 degrees West over the Atlantic Ocean in a geosynchronous orbit,
the satellite position later varied between 45 and 95 degrees West in support
of meteorological operations.  In general, the various experiments were
successful.

    <skos:definition xml:lang="en">Luna 17 was launched from an earth parking orbit towards the Moon and entered lunar orbit on November 15, 1970. The spacecraft soft landed on the Moon in the Sea of Rains. The spacecraft had dual ramps by which the payload, Lunokhod 1, descended to the lunar surface. Lunokhod 1 was a lunar vehicle formed of a tub-like compartment with a large convex lid on eight independently powered wheels. Lunokhod was equipped with a cone-shaped antenna, a highly directional helical antenna, four television cameras, and special extendable devices to impact the lunar soil for soil density and mechanical property tests. An x-ray spectrometer, an x-ray telescope, cosmic-ray detectors, and a laser device were also included. The vehicle was powered by a solar cell array mounted on the underside of the lid. Lunokhod was intended to operate through three lunar days but actually operated for eleven lunar days. The operations of Lunokhod officially ceased on October 4, 1971, the anniversary of Sputnik 1. Lunokhod had traveled 10,540 m and had transmitted more than 20,000 TV pictures and more than 200 TV panoramas. It had also conducted more than 500 lunar soil tests.Group: Platform_Details   Entry_ID: LUNOKHOD   Group: Platform_Identification      Platform_Category: Interplanetary Spacecraft      Short_Name: LUNOKHOD      Long_Name: Lunar Retroreflector Array   End_Group   Group: Synonymous_Platform_Names      Short_Name: Luna 17      Short_Name: Lunik 17      Short_Name: Lunokhod 1      Short_Name: 04691   End_Group   Creation_Date: 2012-07-18   Online_Resource: http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1970-095A   Sample_Image: http://nssdc.gsfc.nasa.gov/thumbnail/spacecraft/luna17.gif   Group: Platform_Logistics      Launch_Date: 1970-11-10      Launch_Site: Baikonur Cosmodrome, Tyuratam, Russia      Primary_Sponsor: U.S.S.R   End_GroupEnd_Group</skos:definition>

Compton wassafely deorbited and re-entered the Earth&apos;s atmosphere on June4, 2000.The objective of the Compton GRO was to make comprehensiveobservations of gamma ray sources throughout the Universe. Theobservatory carried four scientific instruments that made gammaray energy measurements from 0.1 million electron volts to30,000 million electron volts.The end of life was in June 2000.

Old Value=The radiosonde is a balloon-borne instrument platform with radio transmitting capabilities. Originally named a radio-meteorograph, the instrument is now referred to as a radiosonde, a name apparently derived by H. Hergesell from a combination of the words &quot;radio&quot; for the onboard radio transmitter and &quot;sonde&quot;, which is messenger from old English.

The radiosonde contains instruments capable of making direct in-situ measurements of air temperature, humidity and pressure with height, typically to altitudes of approximately 30 km. These observed data are transmitted immediately to the ground station by a radio transmitter located within the instrument package. The ascent of a radiosonde provides an indirect measure of the wind speed and direction at various levels throughout the troposphere. Ground based radio direction finding antenna equipment track the motion of the radiosonde during its ascent through the air. The recorded elevation and azimuth information are converted to wind speed and direction at various levels by triangulation techniques.

    <skos:definition xml:lang="en">The radiosonde is a balloon-borne instrument platform with radio transmitting capabilities. Originally named a radio-meteorograph, the instrument is now referred to as a radiosonde, a name apparently derived by H. Hergesell from a combination of the words &apos;radio&apos; for the onboard radio transmitter and &apos;sonde&apos;, which is messenger from old English.The radiosonde contains instruments capable of making direct in-situ measurements of air temperature, humidity and pressure with height, typically to altitudes of approximately 30 km. These observed data are transmitted immediately to the ground station by a radio transmitter located within the instrument package. The ascent of a radiosonde provides an indirect measure of the wind speed and direction at various levels throughout the troposphere. Ground based radio direction finding antenna equipment track the motion of the radiosonde during its ascent through the air. The recorded elevation and azimuth information are converted to wind speed and direction at various levels by triangulation techniques.</skos:definition>

Old Value=The Rockwell Aero Commander (AC-500S) is a versatile and stable high-winged twin piston-engine aircraft that is suitable for a variety of missions. Standard configuration allows for mission equipment and two pilots. However, with the scientific packages removed, seating for five additional passengers may be installed. NOAA&apos;s two aero commanders are utilized primarily as aerial survey platforms for visual verification of aeronautical charts, high-resolution aerial photography, and snow water equivalent and soil moisture content measurements. Additionally, the aircraft has been used in biological investigations, such as algal bloom measurements and sea turtle population assessments, and post-hurricane and severe flood damage assessment photography.

This program, previously known as DAAP (Data Acquisition and Processing Program), was classified until March 1973. The objectives of this program are to provide global visual and infrared cloud-cover data and specialized environmental data to support Department of Defense requirements. Operationally, the program consisted of two satellites in planned 830-km sun-synchronous polar orbits, with the ascending node of one satellite in early morning and the other at local noon. The 5.4-m long spacecraft was separated into four sections: (1) a precision mounting platform (PMP) for sensors and equipment requiring precise alignment, (2) an equipment support module (ESM) containing the electronics, reaction wheels, and some meteorological sensors, (3) a reaction control equipment (RCE) support structure (including the third-stage motor, hydrazine reaction control system) that supported (4) a 9.29 sq m solar cell panel. The spacecraft stabilization was controlled by a combination flywheel and magnetic control coil system, so that sensors were maintained in the desired &apos;earth-looking&apos; mode. One feature was the precision-pointing accuracy of the primary imager to 0.01 deg provided by a star sensor and an updated ephemeris navigation system. This allowed automatic geographical mapping of the digital imagery to the nearest picture element. The operational line scan system (OLS) built by Westinghouse, was the primary data acquisition system that provided real-time or stored, multi-orbit, day-and-night visual and infrared imagery at 1/3 nautical mile resolution for all major land masses, 1-1/2 nautical mile resolution for complete global coverage, and provided with this data calibration, timing, and other auxiliary signals to the spacecraft for digital transmission to the ground. A supplementary sensor package, the special sensor H (SSH), a step-scanning radiometer, was the infrared temperature-humidity-ozone sounder. The data processing system, which included three high-density tape recorders, was capable of storing a total of 400 min of data, each allowing full global coverage twice daily. Either recorded or real-time data were transmitted to ground-receiving sites by two redundant S-band transmitters. Recorded data were read out to tracking sites located at Fairchild AFB, WA, and Loring AFB, ME, and relayed by SATCOM to Air Fource Global Weather Central, Offutt AFB, NE. Real-time data were read out at mobile tactical sites located around the world. A more complete description of the satellite can be found in the report `The Defense Meteorological Satellite Program,&apos; D.A.

    <skos:definition xml:lang="en">Gemini (GPS-based Orbit Estimation and Laser Metrology forIntersatellite Navigation) is a technology mission, proposed byDLR?s German Space Operations Center (GSOC), Astrium GmbH, andVectronic Aerospace GmbH. aiming The major Gemini missionobjective is the controlled establishment of a satelliteformation in a low-Earth orbit. To that end, advanced in-orbittechnologies will be demonstrated based on laser metrology, aswell as innovative GPS-based approaches to relativenavigation. As part of its technological objectives, the Geminiformation control will entirely be based on an autonomous orbitcontrol approach. Secondary mission objectives concern theseparation concept from the launcher, the drift stop and thedevelopment of a controlled formation acquisition strategy. Asa technology demonstration mission, emphasis is given to anindependent verification of the relative distance by means of alaser radar sensor. To allow a formation flying demonstrationfor a wide ran ge of applications, the technologies for thecontrol of the relative distance cover both the regime of closeand wide formations ranging from several hundreds of meters upto 100 km. In contrast to the relaxed orbit controlrequirements of nowadays formations, Gemini aims at a relativeposition keeping of several cm to several meters, that isexpected to be of significance for many of the upcomingformation flying missions and, in addition, paves the way foreven more advanced requirements, such as for SMART 2. Toachieve that level of control accuracy, the Gemini sensors haveto provide relative position measurements in the range ofmillimeters or better, that may not be achievable solely usinga spaceborne GPS receiver.</skos:definition>

Old Value=The Douglas DC-6 was one of the first airplanes to fly a regularly scheduled around-the-world route. With its higher performance, increased accommodation, greater payload and pressurized cabin, it was a natural evolution of the DC-4.

Although the DC-6 had the same wingspan as the DC-4, its engines helped it fly 90 mph faster than the DC-4, carry 3,000 pounds more payload and fly 850 miles farther. The DC-6 could maintain the cabin pressure of 5,000 feet while flying at 20,000 feet.

American Airlines and United Airlines ordered the commercial DC-6 in 1946, and Pan American Airways used the DC-6 to start tourist-class service across the North Atlantic. The 29th DC-6 was ordered by the Air Force, adapted as the presidential aircraft and designated the VC-118. It was delivered on July 1, 1947, and called The Independence after President Harry Truman&apos;s hometown, Independence, Mo.

The larger, all-cargo DC-6A first flew Sept. 29, 1949; the larger capacity DC-6B, which could seat up 102 people, first flew Feb. 10, 1951. After the Korean War broke out in 1951, the military ordered DC-6As modified as either C-118A &quot;Liftmaster&quot; personnel carriers, as the Navy&apos;s R6D transports or as MC-118As for aeromedical evacuation. Between 1947 and 1959, Douglas built a total of 704 DC-6s, 167 of them military versions. By 1998, the DC-6 was still flying with smaller airlines around the world.

    <skos:definition xml:lang="en">ODIN is a Swedish small satellite project for Astronomical andAtmospheric Research. The Aeronomy research will addressscientific problem areas in the stratosphere and mesosphere bymaking measurements of various trace species. The scientificgoals can be summarized as follows:1. Stratospheric ozone science: To elucidate the geographicalextent of and mechanisms responsible for ozone depletion in the&apos;ozone hole&apos; region and to study dilution effects and possibleheterogeneous chemistry even outside of the polar regions due tosulphate aerosols2. Mesospheric ozone science: To establish the relative role ofodd hydrogen chemistry and the effects of ordered and turbulenttransport and corpuscular radiation.3. Summer mesospheric science: To establish the variability ofmesospheric water vapor including an assessment of the requiredfluxes for aerosol formation in the polar mesosphere.4. Coupling of atmospheric regions: To study some of themechanisms that provide coupling between the upper and loweratmosphere, eg downward transport of aurorally enhanced NO withits effects on ozone photo chemistry and the vertical exchangeof minor species such as odd oxygen, CO and H2O.Odin will work in unexplored bands of the electromagneticspectrum, around wavelengths of 0.5 mm and 3 mm. These containemission lines from important molecules such as water vapor,molecular oxygen, ozone and carbon monoxide. The lines will beused as tools to study processes in the Earth&apos;s atmosphere andin astronomical objects. Complementary information on theatmosphere will come from spectral lines at ultraviolet andoptical wavelengths. Major scientific issues relate to starformation processes interstellar chemistry and atmospheric ozonebalance.Additional information available athttp://www.ssc.se/ssd/ssat/odin.html[Summary provided by Swedish Space Corporation]</skos:definition>

Old Value=NOAA’s GOES-T, the third in a series of four advanced geostationary weather satellites, blasted into orbit aboard a United Launch Alliance Atlas V 541 rocket at 4:38 p.m. ET today from Cape Canaveral, Florida. GOES-T’s mission managers confirmed that its solar arrays successfully deployed at 8:28 p.m. EST, and the satellite was operating on its own power.

GOES-T will track destructive wildfires, lightning, Pacific Ocean-based storms, dense fog, and other hazards that threaten the U.S. West Coast, Hawaii and Alaska. It will also monitor solar activity and space weather to provide early warnings of disruptions to power grids, communications and navigation systems. 


“GOES-T joins the suite of advanced technology providing critical data and imagery to forecasters and researchers tracking hazardous weather and working toward building a climate ready nation,” said NOAA Administrator Rick Spinrad, Ph.D. 

Once GOES-T is positioned in a geostationary orbit 22,300 miles above the Earth, after approximately two weeks, it will be renamed GOES-18. After undergoing a full checkout and validating its six high-tech instruments, the new satellite will move to the GOES-West position and replace GOES-17 in early 2023. 

From there, it will constantly provide advanced imagery and atmospheric measurements. Observations from GOES-18 will be fed into the NOAA&apos;s National Weather Service’s computer models used by meteorologists to develop forecasts and help predict the formation, growth, intensity and movement of hazardous weather systems.

GOES-T’s mission managers confirmed that its solar arrays successfully deployed at 8:28 p.m. EST, and the satellite was operating on its own power.

GOES-T will track destructive wildfires, lightning, Pacific Ocean-based storms, dense fog, and other hazards that threaten the U.S. West Coast, Hawaii and Alaska. It will also monitor solar activity and space weather to provide early warnings of disruptions to power grids, communications and navigation systems. 


“GOES-T joins the suite of advanced technology providing critical data and imagery to forecasters and researchers tracking hazardous weather and working toward building a climate ready nation,” said NOAA Administrator Rick Spinrad, Ph.D. 

Once GOES-T is positioned in a geostationary orbit 22,300 miles above the Earth, after approximately two weeks, it will be renamed GOES-18. After undergoing a full checkout and validating its six high-tech instruments, the new satellite will move to the GOES-West position and replace GOES-17 in early 2023. 

From there, it will constantly provide advanced imagery and atmospheric measurements. Observations from GOES-18 will be fed into the NOAA&apos;s National Weather Service’s computer models used by meteorologists to develop forecasts and help predict the formation, growth, intensity and movement of hazardous weather systems.

text: KMA (Korea Meteorological Administration) is planning for the follow-on geostationary meteorological satellite (GEO-KOMPSAT-2) to continue the Korean COMS (Communications, Ocean, Meteorological Satellite) mission. From 2009 onwards, KMA has prepared a feasibility study for the GEO-KOMPSAT-2 program under the cooperation of the following Ministries: Ministry of Science, ICT and Future Planning (MSIP), Ministry of Oceans and Fisheries (MOF), and Ministry of Environment (ME) of the Korean government. The GEO-KOMPSAT-2 program has been approved in September 2010, and was kicked off in the middle of 2012.
Note: The nickname Cheollian means long distance view (literally “Thousand Li View”) in Korean.

KMA/NMSC (Korea Meteorological Administration/National Meteorological Satellite Center) of Korea started the COMS-Next (GEO-KOMPSAT-2) program with the overall objective to obtain geostationary meteorological data for continuous monitoring of meteorological phenomena in the Asia-Oceania region.

Specific mission goals are: 

• Continuing the COMS (Communication, Ocean and Meteorological Satellite) meteorological mission

• Improving the severe weather monitoring

- Higher frequency of observation

- Retrieving the atmospheric structure (pseudo-sounding)

• Improving the support of the NWP (Numerical Weather Prediction) model with an efficient data assimilation model

• Intensifying the environment &amp; climate monitoring

- Various surface information retrieval

- Air pollution monitoring

- Establishing long-term observation data.

The GEO-KOMPSAT-2 program comprises two satellites for multi-purpose applications: GEO-KOMPSAT-2A for meteorological missions and GEO-KOMPSAT-2B for ocean and environmental monitoring. KARI (Korea Aerospace Research Institute) of Daejeon, Korea, is responsible for the development of the GEO-KOMPSAT-2 space segment while KMA/NMSC implements the ground segment.

    <skos:prefLabel xml:lang="en">GOES-9</skos:prefLabel>
    <skos:definition xml:lang="en">GOES 9 was launched on May 23, 1995. GOES-9, which is currentlypartially operational, is being provided to the Japanese MeteorologicalAgency to replace their failing geostationary satellite.GOES I-M represents the next generation of meteorological satellitesand introduces two new features.  The first feature, flexible scan,offers small-scale area imaging that lets meteorologists take picturesof local weather trouble spots. This allows them to improve short-termforecasts over local areas. The second feature, simultaneous andindependent imaging and sounding, is designed to allow weatherforecasters to use multiple measurements of weather phenomena toincrease the accuracy of their forecasts.Each satellite in the series carries two major instruments: an Imagerand a Sounder. These instruments acquire high resolution visible andinfrared data, as well as temperature and moisture profiles of theatmosphere. They continuously transmit these data to ground terminalswhere the data are processed for rebroadcast to primary weatherservices both in the United States and around the world, including theglobal research community.The GOES I-M mission is scheduled to run from the mid-1990s into thefirst decade of the 21st century.  Each element of the mission hasbeen designed to meet all in-orbit performance requirements for atleast five years.The GOES I-M system performs the following basic functions:+ Acquisition, processing, and dissemination of imaging andsounding data.+ Acquisition and dissemination of Space Environment Monitor(SEM) data.+ Reception and relay of data from ground-based Data CollectionPlatforms (DCPs) that are situated in carefully selected urban andremote areas to the NOAA Command and Data Acquisition (CDA) station.+ Continuous relay of Weather Facsimile (WEFAX) and other data tousers, independent of all other functions.+ Relay of distress signals from people, aircraft, or marine vesselsto the search and rescue ground stations of the Search and RescueSatellite Aided Tracking (SARSAT) system.GOES provides the instantaneous relay functions for the SARSAT system.A dedicated search and rescue transponder on board GOES is designed todetect emergency distress signals originating from Earth-basedsources. These unique identification signals are normally combinedwith signals received by a low-Earth orbiting satellite system andrelayed to a search and rescue ground terminal. The combined data areused to perform effective search and rescue operations.The GOES I-M system serves a region covering the central and easternPacific Ocean; North, Central, and South America; and the central andwestern Atlantic Ocean. Pacific coverage includes Hawaii and the Gulfof Alaska. This is accomplished by two satellites, GOES West locatedat 135 west longitude and GOES East at 75 west longitude. A commonground station, the CDA station located at Wallops, Virginia,supports the interface to both satellites. The NOAA SatelliteOperations Control Center (SOCC), in Suitland, Maryland, providesspacecraft scheduling, health and safety monitoring, and engineeringanalyses.Delivery of products involves ground processing of the raw instrumentdata for radiometric calibration and Earth location information, andretransmission to the satellite for relay to the data user community.The processed data are received at the control center and disseminatedto the National Weather Service&apos;s (NWS) National MeteorologicalCenter, Camp Springs, Maryland, and NWS forecast offices, includingthe National Hurricane Center, Miami, Florida, and the National SevereStorms Forecast Center, Kansas City, Missouri. Processed data are alsoreceived by Department of Defense installations, universities, andnumerous private commercial users.*The GOES-9 satellite was replaced by GOES-10 in July 1998*MAIN SPACECRAFT DESIGN ELEMENTSMission life            5 years, minimumDimensions Main body              2 meter (7 foot) cube Deployed length        27 meters (88 feet)Weight                  2100 kg (4600 lb)Orbit                   Geosynchronous Altitude               36,000 km (22,000 mi) Longitude              75W and 135W Latitude               equatorial, within 0.5 degreePower                   1050 watts &amp;#64 42 volts, solar array; batterybackupLaunch vehicle          Atlas-I/Centaur (GOES-I/K), Atlas-II/Centaur(GOES-L/M)Communications          Imager and Sounder in GVAR format at 2.1Mbits/secGOES-I/M IMAGERThe GOES Imager is a multi-channel instrument designed to senseradiant and solar-reflected energy from sampled areas of theEarth.

    <skos:definition xml:lang="en">[Source: COSMIC Home Page at UCAR, http://www.cosmic.ucar.edu/about.html ]FORMOSAT-3/COSMIC OverviewFORMOSAT-3/COSMIC (F3C) is a joint Taiwan/US science mission for weather, climate, space weather and geodetic research. The F3C mission was successfully launched on 15 April 2006. Six identical micro satellites, each carrying an advanced GPS radio occultation (RO) receiver, a Tiny Ionospheric Photometer (TIP) and a Tri Band Beacon (TBB) were deployed. The satellites have since been raised by Taiwan&apos;s National Space Organization (NSPO) to their final orbit altitude at 800km to achieve an operational constellation of six orbital planes separated by 30 degrees. The payload science data are currently being downloaded every orbit via two NOAA TT&amp;C stations (in Alaska and Norway) and one NSF/NASA station in McMurdo, Antarctica and transferred to the COSMIC Data Analysis and Archival Center (CDAAC) at UCAR in Boulder. The CDAAC currently processes the COSMIC science data in near real time - Ninety percent of RO profiles are delivered to operational weather centers within 3 hours of observation. CDAAC also reprocesses data in a more accurate post-processed mode (within 6 weeks of observation) for COSMIC as well as other missions including GPS/MET, CHAMP, SAC-C, and GRACE.COSMIC is currently providing between 1000-2500 daily RO profiles in the neutral atmosphere, 1000-2500 daily electron density profiles and total electron content arcs, and TIP radiance products. The data have already demonstrated their value for operational weather forecasting, hurricane forecasting, and investigations of the atmospheric boundary layer. The data have been used extensively to test ionospheric models and their use in operational space weather models is under development. COSMIC GPS RO data also have the potential to be of great benefit to climate studies due to their demonstrated high precision and global and diurnal sampling coverage.Group: Platform_Details   Entry_ID: COSMIC/FORMOSAT-3   Group: Platform_Identification      Platform_Category: Solar/Space Observation Satellites      Short_Name: COSMIC/FORMOSAT-3      Long_Name: Constellation Observing System for Meteorology, Ionosphere and Climate   End_Group   Group: Synonymous_Platform_Names      Short_Name: FORMSAT 3A      Short_Name: FORMSAT 3B      Short_Name: FORMSAT 3C      Short_Name: FORMSAT 3D      Short_Name: FORMSAT 3E      Short_Name: FORMSAT 3F      Short_Name: 2006-011A      Short_Name: 2006-011B      Short_Name: 2006-011C      Short_Name: 2006-011D      Short_Name: 2006-011E      Short_Name: 2006-011F   End_Group   Group: Platform_Associated_Instruments      Short_Name: RO      Short_Name: TBB      Short_Name: TIP   End_Group   Group: Orbit      Orbit_Inclination: 72 degrees      Period: 95 m      Perigee: 496 km      Apogee: 540 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Inclined Non-Polar   End_Group   Online_Resource: http://www.cosmic.ucar.edu/   Online_Resource: http://cosmic-io.cosmic.ucar.edu/cdaac/   Online_Resource: http://www.nspo.org.tw/2008e/projects/project3/hot.shtml?right=no   Sample_Image: http://www.cosmic.ucar.edu/images/rocksat.jpg   Group: Platform_Logistics      Launch_Date: 2006-04-15      Launch_Site: Vandenberg Air Force Base, USA      Design_Life: 5 years      Primary_Sponsor: USA/NSF/UCAR      Primary_Sponsor: TAIWAN/NSPO      Primary_Sponsor: USA/NASA      Primary_Sponsor: USA/DOD/USAF      Primary_Sponsor: USA/NOAA      Primary_Sponsor: USA/DOD/ONR   End_GroupEnd_Group</skos:definition>

text: Project Gemini was NASA&apos;s second human spaceflight program. Conducted between projects Mercury and Apollo, Gemini started in 1961 and concluded in 1966. The Gemini spacecraft carried a two-astronaut crew. Ten Gemini crews and 16 individual astronauts flew low Earth orbit (LEO) missions during 1965 and 1966.

Gemini&apos;s objective was the development of space travel techniques to support the Apollo mission to land astronauts on the Moon. In doing so, it allowed the United States to catch up and overcome the lead in human spaceflight capability the Soviet Union had obtained in the early years of the Space Race, by demonstrating: mission endurance up to just under 14 days, longer than the eight days required for a round trip to the Moon; methods of performing extra-vehicular activity (EVA) without tiring; and the orbital maneuvers necessary to achieve rendezvous and docking with another spacecraft.

    <skos:definition xml:lang="en">Project Gemini was NASA&apos;s second human spaceflight program. Conducted between projects Mercury and Apollo, Gemini started in 1961 and concluded in 1966. The Gemini spacecraft carried a two-astronaut crew. Ten Gemini crews and 16 individual astronauts flew low Earth orbit (LEO) missions during 1965 and 1966.Gemini&apos;s objective was the development of space travel techniques to support the Apollo mission to land astronauts on the Moon. In doing so, it allowed the United States to catch up and overcome the lead in human spaceflight capability the Soviet Union had obtained in the early years of the Space Race, by demonstrating: mission endurance up to just under 14 days, longer than the eight days required for a round trip to the Moon; methods of performing extra-vehicular activity (EVA) without tiring; and the orbital maneuvers necessary to achieve rendezvous and docking with another spacecraft.</skos:definition>

Old Value=Explorer 39 was an inflatable sphere, 3.6 m in diameter.  It was orbited to make atmospheric density determinations.  The spacecraft was successfully launched into a nearly polar, highly elliptical orbit.  It was folded and carried into orbit, together with ejection and inflation equipment, as part of the payload of Explorer 40.  Two density experiments were performed.  One involved the study of systematic density variation, and the other was concerned with nonsystematic density changes.  The upper atmospheric densities were derived from sequential observations of the sphere by use of an attached 136.620-MHz radio tracking beacon and by optical tracking. The radio beacon ceased transmitting in June 1971.  Since that time it has been necessary to rely solely on the SAO Baker-Nunn camera network for tracking.  Explorer 39 had an expected orbital lifetime of 50 years.

Explorer 39 had an expected orbital lifetime of 50 years.https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1968-066AGroup: Platform_Details   Entry_ID: AD-C   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: AD (Atmospheric Dynamics)      Short_Name: AD-C      Long_Name: Atmosphere Dynamics C (Explorer 39)   End_Group   Group: Synonymous_Platform_Names      Short_Name: EXPLORER 39      Short_Name: 03337   End_Group   Group: Platform_Associated_Instruments      Short_Name: OPTICAL BEACON   End_Group   Group: Orbit      Orbit_Inclination: 80.6 degrees      Period: 118.2 minutes      Perigee: 670 km      Apogee: 2538 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-08-22   Online_Resource: https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1968-066A   Group: Platform_Logistics      Launch_Date: 1968-08-08      Launch_Site: Vandenberg Air Force Base, USA      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

text: The Geostationary Operational Environmental Satellite Program (GOES) is a joint effort of NASA and the National Oceanic and Atmospheric Administration (NOAA).

The GOES system currently consists of GOES-13, operating as GOES-East, in the eastern part of the constellation at 75 degrees west longitude and GOES-15, operating as GOES-West, at 135 degrees west longitude. The GOES-R series will maintain the two-satellite system implemented by the current GOES series. However, the locations of the operational GOES-R satellites will be 75 degrees west longitude and 137 degrees west longitude. The latter is a shift in order to eliminate conflicts with other satellite systems. The GOES-R series operational lifetime extends through December 2036.

These spacecraft help meteorologists observe and predict local weather events, including thunderstorms, tornadoes, fog, hurricanes, flash floods and other severe weather. In addition, GOES observations have proven helpful in monitoring dust storms, volcanic eruptions and forest fires.

    <skos:definition xml:lang="en">The Meteosat Operational Programme (MOP-2) satellite, launched onMarch 2,1991, was the second operational geostationary Meteosatsatellite following 3 pre-operational Meteosat satellites(Meteosat-1,-2,-3/P2). The primary goal of the MOP satellites were (1)to provide visible and IR day/night cloudcover data and radiances and(2) disseminate image data to users through the Data CollectionPlatform (DCP). MOP-2 (or Meteosat 5) is a 2.1 m diameter, 3.195 mhigh stepped cylindrical body with solar cells on six main bodypanels. The spacecraft is spin-stabilized at 100 rpm around the mainaxis aligned almost parallel to the Earth&apos;s axis with spin regulatedby two small hydrazine thrusters. Spin access control and east-weststationkeeping is provided by two pairs of large thrusters.  Attitudeinformation is provided by Earth horizon and Sun-lit sensors.  Aradiating dipole antenna directs S-band (333 kbs) transmission of DCPimage data to the Data Acquisition, Telemetry, and Tracking Station atOdenwald, Germany for relay to the Meteosat Ground Computer System andMeteosat Operations Control center at ESA&apos;s European Space OperationsCenter(ESOC). The MOP-2 carries a single imaging radiometerinvisible/infrared wavelengths in addition to the Data CollectionPlatform.To view a 3D orbit, observe the J Track satellite tracking web page:http://liftoff.msfc.nasa.gov/RealTime/JTrack/For information on the European Space Agency (ESA) and the MeteosatProgram, see the URL: http://www.esrin.esa.itGroup: Platform_Details   Entry_ID: METEOSAT-5   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: METEOSAT      Short_Name: METEOSAT-5      Long_Name: Meteosat Operational Programme 2 (MOP-2)   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">ROCSat-2 is an NSPO (National Space Program Office) of Taiwan Earth imaging satellite with the objective to collect high-resolution panchromatic (2 m) and multispectral (8 m) imagery for a great variety of applications such as in land use, agriculture and forestry, environmental monitoring, natural disaster evaluation, and in support of research interests, in particular with the ISUAL instrument. Daily image coverage of Taiwan and the surrounding region is required.Background: A contract was signed in May 1999 between NSPO and DASA/DSS (Dornier Satelliten Systeme GmbH) of Germany to build a high-resolution optical imaging satellite. However, the German government refused to give DASA/DSS an export licence for the S/C (the People&apos;s Republic of China was protesting the deal). The stalemate was resolved in Dec. 1999 when NSPO signed a new contract with MMS (now Astrium SAS of France). Quick approval of the export of ROCSat-2 was provided by the French government. The ROCSat program is part of a long-term effort in Taiwan to develop an autonomous space capability.Note: A public naming competition took place in Taiwan in 2004 with regard to the ROCSat satellite program. At the end of this contest, the ROCSat program was given the new name of FormoSat in December 2004. Hence, ROCSat-2 became FormoSat-2. Spacecraft:The spacecraft bus has been built by EADS Astrium SAS (prime contractor) of Vélizy, France, based on the Leostar 500 XO family. There were also contributions from Taiwanese industry (including satellite computers, S-band antennas, and sun sensors). The S/C structure consists basically of a hexagonal body of 1.6 m side length (diameter), 2.4 m in height. The satellite is three-axis stabilized. The upper deck of the platform carries the payload (RSI and ISUAL) and also part of AOCS (Attitude and Orbit Control Subsystem), namely the star sensors and gyroscopes. The lower deck carries the four reaction wheels and the autonomous propulsion module. The pointing accuracy is &amp;lt; 0.7 km (0.12º); the position knowledge is &amp;lt; 70 m (0.02º). The fixed solar array uses GaAs cells and consists of two deployable flaps. The entire S/C architecture is designed in such a way as to provide a low roll inertia, a key factor for satellite agility and instrument line-of-sight stability. The S/C provides a body-pointing capability of ±45º in roll and pitch (45º pitch in 60 s, 10º roll in 25 s, 30º roll in 60 s, respectively). The S/C wet mass is about 746 kg with 81 kg of propellant (N2H4) mass. The design life is five years or better.Launch: A launch of ROCSat-2 took place on May 20, 2004 (UTC) on a Taurus-XL vehicle of OSC (Orbital Sciences Corporation) from VAFB, CA (maiden flight of Taurus-XL configuration which offers greater lift capability compared to previous versions of the Taurus rocket).Orbit: Sun-synchronous circular orbit, mean altitude = 888 km, inclination = 99.14º, period of 102.9 minutes, the LTDN (Local Time of Descending Node) is 9:26 AM (14 orbits/day). The agility of the spacecraft provides a daily revisit capability for event/disaster monitoring.Note: Following the early-orbit checkout, the initial satellite orbit has been raised from 728 km to 888 km altitude in the period May 23 to June 2, 2004. A total of 32 burns were performed by the propulsion module with 4 burns for inclination change, to enter into the mission orbit with an altitude of 891 km and an inclination of 99.14º.Ground segment: The basic elements of the ROCSat-2 ground segment are the MMC (Multi Mission Center) and the XAS (X-band Acquisition System) located in Hsinchu, Taiwan. MMC in turn consists of MOC (Mission Operations Center), MCC (Mission Control Center), SCC (Science Control Center), FDF (Flight Dynamics Facility), and GCN (Ground Communications Network). ROCSat-2 X-band imagery reception is also made available to third parties (international partners) with their own ground stations through cooperative agreements.Mission status: The spacecraft and its payload are operating nominally as of 2007.Mission operations started in June 2004 (the checkout and performance verification for satellite bus and RSI were started on May 21 and completed through June 2004; all performance requirements of FormoSat-2 had been successfully verified in orbit). Besides providing imagery for the domestic needs of Taiwan, the S/C is frequently being used to deliver high-resolution imagery for event monitoring (coverage of the Tsunami in Asia on Dec. 26, 2004 and thereafter, coverage of Hurricane Katarina in Aug. 2005, coverage of Typhoons on the Pacific, coverage of earthquake regions, etc.). The spacecraft is operating nominally as of 2006. 7) 8) 9) 10)• NSPO has contracted to SPOT Image S.A. for the international distribution of FORMOSAT-2 images since June 2004• On 4 July 2004, ISUAL successfully observed the first images of sprites, sprite halo, and elves.• In April 2005, NSPO implemented a terminal in Kiruna, Sweden, to serve as an additional receiving station• In May 2006, NSPO implemented a F2T (FormoSat-2 Terminal) in Svalbard, Norway, to extend the data acquisition capability of the mission.SOH (State-of-Health) trending during two years of mission operations (May 2004-May 2006) on five major subsystems, including AOCS and EPS (Electric Propulsion Subsystem), and one major payload have been conducted. All parameters were well within specifications. The C&amp;amp;DH and the TT&amp;amp;C do not exhibit any SOH problems so far.RSI (Remote Sensing Instrument), built by EADS Astrium SAS, France. RSI is made up of the camera and IPU (Instrument Processing Unit). The camera itself consists of the optical subassembly, the secondary structure, and the FPA (Focal Plane Assembly). The Korsch telescope (mirrors &amp;amp; structure) design and the focal plane structure are being made of SiC (Silicon Carbide). The video electronics, sequencer, DC/DC converter, and compression cards comprise the IPU.RSI utilizes the agility of the satellite bus for stereo imaging over a specific region, continuous imaging over a slender region, and mosaic imaging over a large region. The imaging capability is 8 minutes per orbit, and the imaging areas during one cycle can be one 3000 km x 24 km continuous strip, two 100 km x 24 km stereo pairs, four 100 km x 24 km strips, or eight scenes.ISUAL (Imager of Sprites: Upper Atmospheric Lightning). ISUAL is a joint international research program of NSPO, UCB (University of California at Berkeley), National Cheng Kung University of Taiwan, and Tohoku University, Japan. The objective is to observe the natural upward lightning discharge phenomena toward the ionosphere on top of the troposphere, referred to as TLEs (Transient Luminous Events). The requirements call for: 14)• To determine the location and timing of luminous phenomena above thunder clouds to investigate their spatial, temporal and spectral properties• To obtain a global survey of upper atmospheric optical flash transients (sprites, elves, blue jets, gigantic jets, etc.).The instrument consists of four elements: a) intensified sprite imager, b) a six-channel spectrophotometer, c) a two-channel array photometer, and d) an electronics package. The imager is a staring-type frame CCD camera, taking 180 frames/s with a resolution of 512 x 80 pixels in a FOV of 20º x 3.15º. In Figure 8, the large disk of the ISUAL instrument contains six color filters, which can be rotated to select wavelength for measuring the emission spectrum of red sprites. ISUAL is operated in three modes:• The sprite continuous mode to take images with a sample rate of 100 Hz• The sprite burst mode with a sample rate of 1000 Hz• The auroral mode at a constant rate of 1 sample/s.

    <skos:definition xml:lang="en">Meteosat-2 was launched in June 1981 and was a geostationaryspacecraft that served as part of European Space Agency&apos;s (ESA)contribution to the Global Atmospheric Research Program (GARP).  Aspart of GARP, the satellite helped to supply data required for globaldata sets used in improvement of machine weather forecasts.  Ingeneral, the spacecraft design, instrumentation, and operation weresimilar to SMS/GOES.  The cylindrically shaped spacecraft measured 210cm in diameter and 430 cm in length, including the apogee boost motor.The primary structural members were an equipment platform and acentral tube. The radiometer telescope was mounted on the equipmentplatform and viewed the earth through a special aperture in the sideof the spacecraft. A support structure extended radially out from thecentral tube and was affixed to the solar panels, which formed theouter walls of the spacecraft and provided the primary source ofelectrical power.  Located in the annulus-shaped space between thecentral tube and the solar panels were station-keeping and dynamicscontrol equipment and batteries. Proper spacecraft attitude and spinrate (approximately 100 rpm) were maintained by jet thrusters mountedon the spacecraft and activated by ground command. The spacecraft usedboth UHF-band and S-band frequencies in its telemetry and commandsubsystems.  A low-power VHF transponder provided telemetry andcommand during launch and then served as a backup for the primarysubsystem once the spacecraft attained synchronous orbit.The spin-stabilized spacecraft carried (1) a visible-IR radiometer toprovide high-quality day/night cloudcover data and to take radiancetemperatures of the earth/atmosphere system, and (2) a meteorologicaldata collection system to disseminate image data to user stations, tocollect data from various earth-based platforms, and to relay datafrom polar-orbiting satellites.  Meteosat-1 was maintained on stationbetween 1 degree East and 1 degree West.For information on the European Space Agency (ESA) and the MeteosatProgram, see the URL: http://www.esrin.esa.it-----------------Entry taken from:Taken from the NSSDC System for Information Retrieval and Storage (SIRS).

    <skos:definition xml:lang="en">The Quasi-Zenith Satellite System (QZSS) is a Japanese satellite navigation program planning for a future evolution to the regional satellite navigation system in East Asia and Oceania. A two stage system deployment is planned. In the first step, is the launch of a single satellite (QZS-1) in 2009 for technical validation and application demonstration. The second step involves the launch of the second and third satellites several years later to demonstrate full system operation. JAXA and related research institutes are in charge of technology development and demonstration of GPS complement and augmentation from QZSS.</skos:definition>

    <skos:definition xml:lang="en">Voyager 1 was one of a pair of spacecraft launched to explore the planets of the outer solar system and the interplanetary environment. Each Voyager had as its major objectives at each planet to: (1) investigate the circulation, dynamics, structure, and composition of the planet&apos;s atmosphere; (2) characterize the morphology, geology, and physical state of the satellites of the planet; (3) provide improved values for the mass, size, and shape of the planet, its satellites, and any rings; and, (4) determine the magnetic field structure and characterize the composition and distribution of energetic trapped particles and plasma therein.Originally planned as a Grand Tour of the outer planets, including dual launches to Jupiter, Saturn, and Pluto in 1976-77 and dual launches to Jupiter, Uranus, and Neptune in 1979, budgetary constraints caused a dramatic rescoping of the project to two spacecraft, each of which would go to only Jupiter and Saturn. The new mission was called Mariner Jupiter/Saturn, or MJS. It was subsequently renamed Voyager about six months prior to launch. The rescoped mission was estimated to cost $250 million (through the end of Saturn operations), only a third of what the Grand Tour design would have cost.Originally scheduled to launch twelve days after Voyager 2, Voyager 1&apos;s launch was delayed twice to prevent the occurrence of problems which Voyager 2 experienced after launch. Voyager 1&apos;s launch finally happened on 05 Sept. 1977 and was termed &apos;flawless and accurate&apos;.Although launched sixteen days after Voyager 2, Voyager 1&apos;s trajectory was the quicker one to Jupiter. On 15 Dec. 1977, while both spacecraft were in the asteroid belt, Voyager 1 surpassed Voyager 2&apos;s distance from the Sun. Voyager 1 then proceeded to Jupiter (making its closest approach on 05 March 1979) and Saturn (with closest approach on 12 Nov. 1980). Both prior to and after planetary encounters observations were made of the interplanetary medium. Some 18,000 images of Jupiter and its satellites were taken by Voyager 1. In addition, roughly 16,000 images of Saturn, its rings and satellites were obtained.After its encounter with Saturn, Voyager 1 remained relatively quiescent, continuing to make in situ observations of the interplanetary environment and UV observations of stars. After nearly nine years of dormancy, Voyager 1&apos;s cameras were once again turned on to take a series of pictures. On 14 Feb. 1990, Voyager 1 looked back from whence it came and took the first &apos;family portrait&apos; of the solar system, a mosaic of 60 frames of the Sun and six of the planets (Venus, Earth, Jupiter, Saturn, Uranus, and Neptune) as seen from &apos;outside&apos; the solar system. After this final look back, the cameras on Voyager 1 were once again turned off.

The Defense Meteorological Satellite Program (DMSP) is a Department of Defense (DoD) program run by the Air Force Space and Missle Systems Center (SMC). The program designs, builds, launches, and maintains satellites monitoring the meteorological, oceanographic, and solar-terrestrial physics environments. Each DMSP satellite has a above the surface of the earth. The visible and infrared sensors (OLS) collect images across a 3000 km swath, providing global coverage twice per day. The combination of day/night and dawn/dusk satellites allows monitoring of global information such as clouds every 6 hours. The microwave imager (MI) and sounders (T1, T2) cover one half the width of the visible and infrared swath. These instruments cover polar regions at least twice and the equatorial region once per day. The space environment sensors (J4, M, IES) record along-track plasma densities, velocities, composition and drifts. The data from the DMSP satellites are received and used at operational centers continuously.

    <skos:definition xml:lang="en">VENERA Mission Description:Venera 13 and 14 were identical spacecraft built to takeadvantage of the 1981 Venus launch opportunity and launched 5days apart. The Venera 13 mission consisted of a bus (81-106A)and an attached descent craft (81-106D). The Venera 13 descentcraft/lander was a hermetically sealed pressure vessel, whichcontained most of the instrumentation and electronics, mountedon a ring-shaped landing platform and topped by an antenna. Thedesign was similar to the earlier Venera 9-12 landers. Itcarried instruments to take chemical and isotopic measurements,monitor the spectrum of scattered sunlight, and record electricdischarges during its descent phase through the Venusianatmosphere. The spacecraft utilized a camera system, an X-rayfluorescence spectrometer, a screw drill and surface sampler, adynamic penetrometer, and a seismometer to conductinvestigations on the surface.  After launch and a four monthcruise to Venus, the descent vehicle separated from the bus andplunged into the Venus atmosphere on 1 March 1982. Afterentering the atmosphere a parachute was deployed. At an altitudeof 47 km the parachute was released and simple airbraking wasused the rest of the way to the surface. Venera 13 landed about950 km northeast of Venera 14 at 7 deg 30 min S, 303 E, justeast of the eastern extension of an elevated region known asPhoebe Regio. The area was composed of bedrock outcropssurrounded by dark, fine-grained soil. After landing an imagingpanorama was started and a mechanical drilling arm reached tothe surface and obtained a sample, which was deposited in ahermetically sealed chamber, maintained at 30 degrees C and apressure of about .05 atmospheres. The composition of the sampledetermined by the X-ray flourescence spectrometer put it in theclass of weakly differentiated melanocratic alkalinegabbroids. The lander survived for 127 !  minutes (the planneddesign life was 32 minutes) in an environment with a temperatureof 457 degrees C and a pressure of 84 Earth atmospheres. Thedescent vehicle transmitted data to the bus, which acted as adata relay as it flew by Venus.More info athttp://nssdc.gsfc.nasa.gov/imgcat/html/mission_page/VN_Venera_13_Lander_page1.html[Source: NASA]Group: Platform_Details   Entry_ID: VENERA-13   Group: Platform_Identification      Platform_Category: Interplanetary Spacecraft      Platform_Series_or_Entity: LANDER      Short_Name: VENERA-13   End_Group   Group: Synonymous_Platform_Names      Short_Name: VENERA 13   End_Group   Group: Platform_Associated_Instruments      Short_Name: FLUORESCENCE SPECTROSCOPY   End_Group   Creation_Date: 2007-12-13   Online_Resource: http://heasarc.gsfc.nasa.gov/docs/heasarc/missions/venera1314.html   Sample_Image: http://nssdc.gsfc.nasa.gov/imgcat/midres/v13_vg261_262.gif   Group: Platform_Logistics      Launch_Date: 1981-10-30      Launch_Site: Baikonur Cosmodrome, Tyuratam, Russia      Primary_Sponsor: Russia   End_GroupEnd_Group</skos:definition>

    <skos:prefLabel xml:lang="en">MARINER 2</skos:prefLabel>
    <skos:definition xml:lang="en">The Mariner 2 spacecraft was the second of a series of spacecraft used for planetary exploration in the flyby, or nonlanding, mode and the first spacecraft to successfully encounter another planet. Mariner 2 was a backup for the Mariner 1 mission which failed shortly after launch to Venus. The objective of the Mariner 2 mission was to fly by Venus and return data on the planet&apos;s atmosphere, magnetic field, charged particle environment, and mass. It also made measurements of the interplanetary medium during its cruise to Venus and after the flyby. Spacecraft and Subsystems Mariner 2 consisted of a hexagonal base, 1.04 meters across and 0.36 meters thick, which contained six magnesium chassis housing the electronics for the science experiments, communications, data encoding, computing, timing, and attitude control, and the power control, battery, and battery charger, as well as the attitude control gas bottles and the rocket engine. On top of the base was a tall pyramid-shaped mast on which the science experiments were mounted which brought the total height of the spacecraft to 3.66 meters. Attached to either side of the base were rectangular solar panel wings with a total span of 5.05 meters and width of 0.76 meters. Attached by an arm to one side of the base and extending below the spacecraft was a large directional dish antenna. The Mariner 2 power system consisted of the two solar cell wings, one 183 cm by 76 cm and the other 152 cm by 76 cm (with a 31 cm dacron extension (a solar sail) to balance the solar pressure on the panels) which powered the craft directly or recharged a 1000 Watt-hour sealed silver-zinc cell battery, which was used before the panels were deployed, when the panels were not illuminated by the Sun, and when loads were heavy. A power-switching and booster regulator device controlled the power flow. Communications consisted of a 3 Watt transmitter capable of continuous telemetry operation, the large high gain directional dish antenna, a cylindrical omnidirectional antenna at the top of the instrument mast, and two command antennas, one on the end of either solar panel, which received instructions for midcourse maneuvers and other functions. Propulsion for midcourse maneuvers was supplied by a monopropellant (anhydrous hydrazine) 225 N retro-rocket. The hydrazine was ignited using nitrogen tetroxide and aluminum oxide pellets, and thrust direction was controlled by four jet vanes situated below the thrust chamber. Attitude control with a 1 degree pointing error was maintained by a system of nitrogen gas jets. The Sun and Earth were used as references for attitude stabilization. Overall timing and control was performed by a digital Central Computer and Sequencer. Thermal control was achieved through the use of passive reflecting and absorbing surfaces, thermal shields, and movable louvers. The scientific experiments were mounted on the instrument mast and base. A magnetometer was attached to the top of the mast below the omnidirectional antenna. Particle detectors were mounted halfway up the mast, along with the cosmic ray detector. A cosmic dust detector and solar plasma spectrometer detector were attached to the top edges of the spacecraft base. A microwave radiometer and an infrared radiometer and the radiometer reference horns were rigidly mounted to a 48 cm diameter parabolic radiometer antenna mounted near the bottom of the mast. All instruments were operated throughout the cruise and encounter modes except the radiometers, which were only used in the immediate vicinity of Venus.

    <skos:definition xml:lang="en">The ITOS (Improved Tiros Operational Satellite) series (TIROS-Mwas the prototype spacecraft) were the second generation ofoperational sun-synchronous meteorologicalspacecraft. Operational satellites were renamed NOAA.The primary objective of ITOS was to provide improvedoperational infrared and visual observations of earth cloudcover for use in weather analysis and forecasting. Secondaryobjectives included providing both solar proton and global heatbalance data on a regular daily basis. To accomplish thesetasks, the spacecraft carried:-two television cameras for Automatic Picture Transmission (APT) and-two Advanced Vidicon Camera System (AVCS) cameras. It also carried-a low-resolution Flat Plate Radiometer (FPR),-a Solar Proton Monitor (SPM), and-two scanning radiometers that not only measured emitted infraredradiation, but also served as a backup system for the APT and AVCScameras.The nearly cubical spacecraft measured 1 by 1 by 1.2 m. The TVcameras and infrared sensors were mounted on the satellitebaseplate with their optical axes directed verticiallyearthward. The satellite was equipped with three curved solarpanels that were folded during launch and deployed after orbitwas achieved. Each panel measured over 4.2 m in length whenunfolded and was covered with 3420 solar cells, each measuring 2by 2 cm. The ITOS dynamics and attitude control systemmaintained desired spacecraft orientation through gyroscopicprinciples incorporated into the satellite design. Earthorientation of the satellite body was maintained by takingadvantage of the precession induced from a momentum flywheel sothat the satellite body precession rate of one revolution perorbit provided the desired &apos;earth looking&apos; attitude. Minoradjustments in attitude and orientation were made by means ofmagnetic coils and by varying the speed of the momentumflywheel.Additional information available at&apos;http://www.skyrocket.de/space/doc_sdat/noaa_itos-a.htm&apos;Group: Platform_Details   Entry_ID: TIROS-M   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: TIROS      Short_Name: TIROS-M      Long_Name: Television Infrared Observation Satellite-M   End_Group   Group: Synonymous_Platform_Names      Short_Name: ITOS   End_Group   Group: Platform_Associated_Instruments      Short_Name: HRIR   End_Group   Creation_Date: 2007-11-14   Online_Resource: http://www.skyrocket.de/space/doc_sdat/noaa_itos-a.htm   Sample_Image: http://www.photolib.noaa.gov/700s/spac0170.jpg   Group: Platform_Logistics      Launch_Date: 1970-01-23      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">SSTL developed the UK-DMC-1 satellite (also known as BNSCsat-1) for the British National Space Centre (BNSC) under a grant from the Microsatellite Applications in Collaboration (MOSAIC) programme. Through UK-DMC, BNSC became the anchor tenant for the SSTL-led Disaster Monitoring Constellation (DMC), accelerating the formation of a full international consortium.UK-DMC is a satellite of the standard Disaster Monitoring Constellation (DMC) design, with added research and development payloads. Like all of the standard DMC satellites, it carries an optical imaging payload developed by SSTL to provide 32-m ground resolution with an exceptionally wide swath width of over 640 km. The payload uses green, red and near infrared bands equivalent to Landsat TM+ bands 2, 3 and 4. In comparison to the other DMC satellites, UK-DMC features increased on-board data storage, with 1.5 gigabyte capacity. Images are returned to the SSTL mission operations centre using the Internet Protocol over an 8-Mbps S-band downlink.UK-DMC also contains a commercial Internet router from Cisco Systems, which builds on the use of the Internet Protocol by the DMC satellites to experiment with Internet packet routing to and in space.UK-DMC has also provided an opportunity for SSTL to test a new concept in remote sensing, GPS reflectometry. This technique, which measures the signals from the GPS navigation system after they are reflected off the sea, could revolutionize oceanographic remote sensing. If UK-DMC validates theories of GPS reflectometry, the technique could one day enable satellites to measure the height of waves on the high seas, providing important data to ship owners and operators. SSTL is using imagery from the UK-DMC to investigate the full range of uses for large-coverage images with medium spatial resolution and high temporal resolution. The UK-DMC satellite will also operate as part of a constellation providing images to disaster relief agencies worldwide in times of need.Group: Platform_Details   Entry_ID: UK-DMC   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: UK-DMC   End_Group   Group: Synonymous_Platform_Names      Short_Name: BNSCSAT   End_Group   Group: Platform_Associated_Instruments      Short_Name: GPS      Short_Name: SLIM-6   End_Group   Group: Orbit      Orbit_Altitude: 686 Km      Orbit_Inclination: 98.0 degrees      Period: 98.4 min      Perigee: 675      Apogee: 692      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2008-06-04   Online_Resource: https://earth.esa.int/web/guest/missions/3rd-party-missions/current-missions/uk-dmc   Online_Resource: https://directory.eoportal.org/web/eoportal/satellite-missions/u/uk-dmc-2   Group: Platform_Logistics      Launch_Date: 2003-09-27      Launch_Site: Plesetsk Cosmodrome, Russia      Primary_Sponsor: British National Space Centre (BNSC)      Primary_Sponsor: Surrey Satellite Technology Ltd.

text: The ESSA-9 satellite replaced ESSA-7 and provided cloud-cover photography to the US&apos;s National Meteorological Center for the purpose of preparing operational weather analyses and forecasts. The spacecraft was an 18-sided polygon, 42 inches in diameter, 22 inches high and weighed 320 pounds. The craft was made of aluminum alloy and stainless steel then covered with 10,020 solar cells. The solar cells served to charge the 63 nickel-cadmium batteries.

The two cameras were mounted 180-degrees opposite each other along the side of the cylindrical craft. The &quot;cartwheel&quot; configuration of the TIROS-9 was selected as the orbital configuration of the operational series of ESSA satellites. Therefore, a camera could be pointed at some point on Earth every time the satellite rotated along its axis. The spacecraft operating system was the same as on the TIROS-9. The craft was placed in its planned Sun-synchronous 102-degree inclination retrograde orbit. The satellite spin axis was rotated using the magnetic attitude control system into an alignment perpendicular to the orbital plane and tangent to the Earth&apos;s surface. The ESSA-7 system transmitted images covering 2000-square mile areas with 2-mile resolution from every location once per day. Two arrays of radiometer sensors were also mounted 180-degrees apart to measure the global distribution of solar radiation reflected by the Earth and the Earth&apos;s atmosphere, as well as the long wave emissions from the Earth (a contribution from the NIMBUS program).

    <skos:definition xml:lang="en">TopSat is a micro-satellite designed and built by a QinetiQ-led consortium of British firms. Images from the satellite are provided free of charge to relief agencies responding to disasters anywhere in world.TopSat was designed and built by a consortium of British companies led by QinetiQ, whose role included systems design and technical authority, provision of payload electronics units, project and operations management and data reception. Other consortium members are Surrey Satellite Technology Ltd (SSTL), Rutherford Appleton Laboratory (RAL) designed and Infoterra.The satellite is designed to return its data directly to a mobile ground station immediately after collecting an image, allowing far more timely delivery of the information which it collects than standard satellites. The system is specifically designed to meet operational timescales, whether for disaster relief, news-gathering, or other applications where speed of response is vital.TopSat received the Aviation and Space Grand Award – the top award for aerospace technology, from Popular Science, the best selling science and technology magazine in the world. The magazine’s editors concluded that TopSat is an innovation that has the potential to change satellite and space reconnaissance technology.TopSat weighs just 120 kg, but carries an optical camera capable of delivering panchromatic images with a spatial resolution at nadir of 2.8 metres covering a 17x17 km area, and simultaneous three-band multi-spectral images, (red, green, blue), with a resolution of 5.6 metres. This is thought to represent the best resolution per mass of any satellite launched to date. This camera is integrated with an agile micro-satellite platform to permit pitch compensation manoeuvres, allowing imaging of low illumination scenes.TopSat has been in operation since its launch from Plesetsk in Russia on 27th October 2005. The satellite can be reprogrammed in orbit, and the consortium is exploiting this to enhance its performance. In addition to actively pursuing experiments for the MOD and BNSC, the consortium is also seeking new applications to which the technology can be applied. In the future, a constellation of three or four TopSat satellites could image almost any point on the Earth at least once a day, further opening up the potential for quick response imagery which is extremely cost effective to deliver.[Information from QinetiQ Ltd.]Group: Platform_Details   Entry_ID: TOPSAT   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: TOPSAT   End_Group   Group: Platform_Associated_Instruments      Short_Name: CAMERAS   End_Group   Group: Orbit      Orbit_Inclination: 98.1      Period: 98.6      Repeat_Cycle: 4      Perigee: 688.4      Apogee: 714      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2008-06-18   Online_Resource: http://www.qinetiq.com/home/defence/defence_solutions/space/topsat.html   Online_Resource: http://earth.esa.int/object/index.cfm?fobjectid=5135   Group: Platform_Logistics      Launch_Date: 2005-10-27      Launch_Site: Plesetsk Cosmodrome, Russia      Primary_Sponsor: QinetiQ Ltd.

text: One of a series of meteorological satellites developed and operated by the Air Force under the Defense Meteorological Satellite Program (DMSP). This program, previously known as DAPP (Data Acquisition and Processing Program), was classified until March 1973. The objective of this program is to provide global visual and infrared cloudcover data and specialized environmental data to support Department of Defense operational weather analysis and forecasting requirements. Operationally, the program consists of two satellites in planned 830-km, sun-synchronous polar orbits, with the ascending node of one satellite in early morning and the other at local noon. The 6.4-m-long spacecraft is separated into four sections: (1) a precision mounting platform for sensors and equipment requiring precise alignment; (2) an equipment support module containing the electronics, reaction wheels, and some meteorological sensors; (3) a reaction control equipment support structure containing the third-stage rocket motor and supporting the ascent phase reaction control equipment; and (4) a 9.29-sq-m solar cell panel. The spacecraft stabilization is controlled by a combination flywheel and magnetic control coil system so sensors are maintained in the desired &quot;earth-looking&quot; mode. One feature is the precision-pointing accuracy of the primary imager to 0.01 deg provided by a star sensor and an updated ephemeris navigation system. This allows automatic geographical mapping of the digital imagery to the nearest picture element. The operational linescan system is the primary data acquisition system that provides real-time or stored, multi-orbit, day-and-night visual and infrared imagery of clouds. A supplementary sensor package contains four special sensors: (1) an advanced X-ray spectrometer, (2) an ionospheric/scintillation monitor, (3) a precipitating electron/ion spectrometer, and (4) an infrared temperature and moisture sounder. Either recorded or real-time data are transmitted to ground-receiving sites by two redundant S-band transmitters. Recorded data are read out to tracking sites located at Fairchild AFB, Washington, and at Loring AFB, Maine, and relayed by SATCOM to Air Force Global Weather Center, Offutt AFB, Nebraska. Real-time data are read out at mobile tactical sites located around the world.

    <skos:definition xml:lang="en">The Heat Capacity Mapping Mission (HCMM) spacecraft was the first of a seriesof Applications Explorer Missions (AEM).  The objective of the HCMM was toprovide comprehensive, accurate, high-spatial-resolution thermal surveys of thesurface of the earth.  The HCMM spacecraft was made of two distinct modules:(1) an instrument module, containing the heat capacity mapping radiometer andits supporting gear, and (2) a base module, containing the data handling,power, communications, command, and attitude control subsystems required tosupport the instrument module.  The spacecraft was spin stabilized at a rate of14 rpm.The HCMM circular sun-synchronous orbit allowed the spacecraft to sense surfacetemperatures near the maximum and minimum of the diurnal cycle.  The orbit hada daylight ascending node with nominal equatorial crossing time of 2:00 p.m.Since there was no inclination adjustment capacity, the spacecraft drifted fromthis crossing time by about 1 hour earlier per year.  There was no on-boarddata storage capability, so only real-time data were transmitted when thesatellite came within reception range of seven ground stations.  The repeatcycle of the spacecraft was 16 days.  Day/night coverage over a given areabetween the latitudes of 85 deg N and 85 deg S occurred at intervals rangingfrom 12 to 36 h (once every 16 days).During February  21-23, 1980, the HCMM orbital altitude was lowered from 620 kmto 540 km to stop the drift of the orbit plane to unfavorable sun angles whichin turn reduced the power collection capability of the solar panels.  Theoperations of the spacecraft were terminated on September 30, 1980.

    <skos:prefLabel xml:lang="en">VOYAGER 2</skos:prefLabel>
    <skos:definition xml:lang="en">Voyager 2 was one of a pair of spacecraft launched to explore the planets of the outer solar system and the interplanetary environment. Each Voyager had as its major objectives at each planet to: (1) investigate the circulation, dynamics, structure, and composition of the planet&apos;s atmosphere; (2) characterize the morphology, geology, and physical state of the satellites of the planet; (3) provide improved values for the mass, size, and shape of the planet, its satellites, and any rings; and, (4) determine the magnetic field structure and characterize the composition and distribution of energetic trapped particles and plasma therein.Originally planned as a Grand Tour of the outer planets, including dual launches to Jupiter, Saturn, and Pluto in 1976-77 and dual launches to Jupiter, Uranus, and Neptune in 1979, budgetary constraints caused a dramatic rescoping of the project to two spacecraft, each of which would go to only Jupiter and Saturn. The new mission was called Mariner Jupiter/Saturn, or MJS. It was subsequently renamed Voyager about six months prior to launch. The rescoped mission was estimated to cost $250 million (through the end of Saturn operations), only a third of what the Grand Tour design would have cost.Voyager 2 was the first of the two spacecraft to be launched, with liftoff occurring 20 Aug. 1977. What was at first an auspicious launch, however, proved to be the beginning of a number of problems. The primary cause of the initial problems were attributed to commanding by the AACS, including difficulty in determining the full deployment of the science boom. These problems resulted in a delay of four days in the launch of Voyager 1 to ensure they wouldn&apos;t occur for it.Although launched sixteen days after Voyager 2, Voyager 1&apos;s trajectory was the quicker one to Jupiter. On 15 Dec. 1977, while both spacecraft were in the asteroid belt, Voyager 1 surpassed Voyager 2&apos;s distance from the Sun.Several months after launch, in April 1978, Voyager 2&apos;s primary radio receiver failed, automatically kicking in the backup receiver which proved to be faulty. Attempts to recover the use of the primary receiver failed and the backup receiver was used for the remainder of the mission. Although use of the backup receiver made communication with the spacecraft more difficult, engineers were able to find workarounds.Voyager 2 proceeded with its primary mission and flew by Jupiter (closest approach on 09 July 1979) and Saturn (05 Aug. 1981). During these flybys, Voyager 2 obtained images roughly equal in number to Voyager 1 (18,000 at Jupiter, 16,000 at Saturn).Voyager 2&apos;s launch date had preserved one part of the original Grand Tour design, i.e. the possibility of an extended mission to Uranus and Neptune. Despite the difficulties encountered, scientists and engineers had been able to make Voyager enormously successful. As a result, approval was granted to extend the mission, first to Uranus, then to Neptune and later to continue observations well past Neptune. Voyager 2 made successful flybys of Uranus (24 Jan. 1986) and Neptune (25 Aug. 1989). Because of the additional distance of these two planets, adaptations had to made to accomodate the lower light levels and decreased communications. Voyager 2 was successfully able to obtain about 8,000 images of Uranus and its satellites. Additional improvements in the on-board software and use of image compression techniques allowed about 10,000 images of Neptune and its satellites to be taken.All of the experiments on Voyager 2 have produced useful data.

This program, previously known as DAPP (Data Acquisition and Processing Program), was classified until March 1973. The objective of this program is to provide global visual and infrared cloudcover data and specialized environmental data to support Department of Defense operational weather analysis and forecasting requirements. Operationally, the program consists of two satellites in sun-synchronous polar orbits, with the ascending node of one satellite in early morning and the other at local noon. The 6.4-m-long spacecraft is separated into four sections: (1) a precision mounting platform for sensors and equipment requiring precise alignment; (2) an equipment support module containing the electronics, reaction wheels, and some meteorological sensors; (3) a reaction control equipment support structure containing the third-stage rocket motor and supporting the ascent phase reaction control equipment; and (4) a 9.29-sq-m solar cell panel. The spacecraft stabilization is controlled by a combination flywheel and magnetic control coil system so that sensors are maintained in the desired earth-looking mode. One feature is the precision-pointing accuracy of the primary imager to 0.01 deg provided by a star sensor and an updated ephemeris navigation system. This allows automatic geographical mapping of the digital imagery to the nearest picture element. The operational linescan system is the primary data acquisition system that provides real-time or stored, multi-orbit, day-and-night, visual and infrared imagery of clouds. A supplementary sensor package contains five special sensors: (1) a microwave temperature sounder, (2) an advanced X-ray detector, (3) an ionospheric/scintillation monitor, (4) a precipitating electron/ion spectrometer, and (5) a microwave imager. Either recorded or real-time data are transmitted to ground-receiving sites by two redundant S-band transmitters. Recorded data are read out to tracking sites located at Fairchild AFB, Washington, and at Loring AFB, Maine, and relayed by SATCOM to Air Force Global Weather Central, Offutt AFB, Nebraska. Real-time data are read out at mobile tactical sites located around the world. Additional information concerning this satellite can be found in the report by D. A.

    <skos:definition xml:lang="en">[Source: National Space Science Data Center, http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=2003-048A ]DMSP F16 (USA 172) was launched by a Titan 2 rocket from Vandenberg AFB at 16:17 UT on 18 October 2003. The Defense Meteorological Satellite Program (DMSP) is a Department of Defense (DoD) program run by the Air Force Space and Missle Systems Center (SMC). The program designs, builds, launches, and maintains satellites monitoring the meteorological, oceanographic, and solar-terrestrial physics environments. Each DMSP satellite has a 101 minute, sun-synchronous near-polar orbit at an altitude of 830km above the surface of the earth. The visible and infrared sensors (OLS) collect images across a 3000 km swath, providing global coverage twice per day. The combination of day/night and dawn/dusk satellites allows monitoring of global information such as clouds every 6 hours. The microwave imager (SSMI) and sounders (SSMT1, SSMT2) cover one half the width of the visible and infrared swath. These instruments cover polar regions at least twice and the equatorial region once per day. The space environment sensors (SSJ, SSM, SSIES) record along-track plasma densities, velocities, composition and drifts (SS stands for Special Sensor).DMSP F16 carries two new experiments: the limb scanning ultraviolet imager/spectrometer SSULI built by the Naval Research Laboratory and the nadir scanning ultaviolet imager/spectrometer and photometer SSUSI built by the Applied Physics Laboratory at Johns Hopkins University. It also carried new versions of the Special Sensor for Ions, Electrons and Scintillations (SSIES-13) and of the precipitating ion and electron monitor (SSJ-5)The data from the DMSP satellites are received and used at operational centers continuously. The data are sent to the National Geophysical Data Center&apos;s Solar Terrestrial Physics Division (NGDC/STP) by the Air Force Weather Agency (AFWA) for creation of an archive.

    <skos:definition xml:lang="en">[Source: National Space Science Data Center, http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1976-091A ]DMSP-5D-1/F1 was one of a series of meteorological satellites developed and operated by the Air Force under the Defense Meteorological Satellite Program (DMSP). This program, previously known as DAAP (Data Acquisition and Processing Program), was classified until March 1973. The objectives of this program were to provide global visual and infrared cloud cover data and specialized environmental data to support Department of Defense requirements. Operationally, the program consisted of two satellites in planned 83-km sun-synchronous polar orbits, with the ascending node of one satellite in early morning and the other at local noon. The 5.4-m-long spacecraft was separated into four sections: (1) a precision mounting platform (PMP) for sensors and equipment requiring precise alignment, (2) an equipment support module (ESM) containing the electronics, reaction wheels, and some meteorological sensors, (3) a reaction control equipment (RCE) support structure (that has the third-stage motor, hydrazine reaction control system) which supports (4) a 9.29 sq m solar cell panel. The Block 5D spacecraft stabilization was controlled by a conbination flywheel and magnetic control coil system so sensors could be maintained in the desired &apos;earth-looking&apos; mode. One feature of Block 5D was the precision-pointing accuracy of the primary imager to 0.01 deg provided by a star sensor and an updated ephemeris navigation system. This allowed automatic geographical mapping of the digital imagery to the nearest picture element. The operational line scan system (OLS) built by Westinghouse, was the primary acquisition system that provided real-time or stored, multi-orbit, day-and-night visual and infrared imagery at 1/3 nautical mile resolution for all major land masses, 1-1/2 nautical mile resolution for complete global coverage, and provided with this data calibration, timing, and other auxiliary signals to the spacecraft for digital transmission to the ground. A supplementary sensor package, the special sensor H (SSH), a step-scanning radiometer, was the infrared temperature-humidity-ozone sounder. The data processing system, which included three high-density tape recorders, could store a total of 400 min of data, each allowing full global coverage twice daily. Either recorded or real-time data were transmitted to ground-receiving sites via two redundant s-band transmitters. Recorded data were read out to tracking sites located at Fairchild AFB, WA, and Loring AFB, ME, and relayed via SATCOM to Air Force Global Weather Central, Offutt AFB, NE. Real-time data were read out at mobile tactical sites located around the world.

This system consisted ofa pair of ESSA satellites in sun-synchronous (polar) orbit.  The oddnumbered satellites (ESSA-1, 3, 5, 7, and 9) utilized the AdvancedVidicon Camera System (AVCS) to obtain global imagery which weretransmitted to the ESSA Command and Data Acquition (CDA) stations atWallops, Virginia, and Fairbanks, Alaska.  The CDA stations relayed thedata to the National Environmental Satellite Service (NESS), which laterbecame the National Environmental Satellite, Data, and InformationService (NESDIS), located in Suitland, Maryland, for processing anddistribution to forecasting centers of the U.S. and other nations.  Theeven numbered satellites (ESSA-2, 4, 6, and 8) were equipped withAutomatic Picture Transmission (APT) TV cameras which transmittedtelevision pictures directly to ground stations worldwide.-----------------Entry taken from:Rao, P.K., S.J.

    <skos:definition xml:lang="en">The Meteosat Operational Programme (MOP-3) satellite, launched onNovember 20, 1993, was the third operational geostationary Meteosatsatellite following 3 pre-operational Meteosat satellites(Meteosat-1,-2,-3/P2).  The primary goal of the MOP satellites were(1) to provide visible and IR day/night cloudcover data and radiancesand (2) disseminate image data to users through the Data CollectionPlatform (DCP). MOP-3 (or Meteosat 6) is a 2.1 m diameter, 3.195 mhigh stepped cylindrical body with solar cells on six main bodypanels. The spacecraft is spin-stabilized at 100 rpm around the mainaxis aligned almost parallel to the Earth&apos;s axis with spin regulatedby two small hydrazine thrusters. Spin access control and east-weststationkeeping is provided by two pairs of large thrusters. Attitudeinformation is provided by Earth horizon and Sun-lit sensors. Aradiating diplole antenna directs S-band (333 kbs) transmission of DCPimage data to the Data Acquisition, Telemetry, and Tracking Station atOdenwald, Germany for relay to the Meteosat Ground Computer System andMeteosat Operations Control center at ESA&apos;s European Space OperationsCenter (ESOC). The MOP-3 carries a single imaging radiometer invisible/infrared wavelengths in addition to the Data CollectionPlatform.To view a 3D orbit, observe the J Track satellite tracking web page:http://liftoff.msfc.nasa.gov/RealTime/JTrack/For more information on the European Space Agency (ESA) and theMeteosat Program, see the URL: http://www.esrin.esa.itGroup: Platform_Details   Entry_ID: METEOSAT-6   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: METEOSAT      Short_Name: METEOSAT-6      Long_Name: Meteosat Operational Programme 3 (MOP-3)   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The Geostationary Meteorological Satellite (GMS-1) was Japan&apos;s contribution to the international GARP (Global Atmospheric Research Program).  One major objective of GARP was to obtain synoptic global meteorological data sets for one year&apos;s duration (to include two optimized observing periods of a few weeks each).  These data served as raw material to optimize computer models for meteorological prediction.  It was hoped that determination could be made of the time limitation for short-term modeling.  The GMS series has been used for the World Meteorological Organization&apos;s World Weather Watch. The satellite was spin-stabilized with a despun earth-pointing antenna.  The GMS series carried the Visible and Spin Scan Radiometer (VISSR).  Launched by a US Delta rocket in July 1977, the satellite was positioned near 140 deg E.  Designed to operate for 5 years, the satellite was turned off in 1981 after 4 1/2 years in orbit.__________Taken from the NSSDC System for Information Retrieval and Storage (SIRS).

This, coupled with their polar and “sun-synchronous” orbits, allows each DMSP weather satellite to monitor nearly the entire globe every six hours.The data collected by the satellites is transmitted to the ground where a team of meteorologists interpret the data and disseminate the information for the U.S. military, which in turn uses the data to plan and conduct U.S. military operations around the globe.In addition to DMSP F18, two more DMSP weather satellites are awaiting launch. These satellites are currently stored at Space Systems’ operations in Sunnyvale, California. They will be transported to Vandenberg upon the request of the Air Force for launch operations.Group: Platform_Details   Entry_ID: DMSP 5D-3/F18   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: DMSP (Defense Meteorological Satellite Program)      Short_Name: DMSP 5D-3/F18      Long_Name: Defense Meteorological Satellite Program-F18   End_Group   Creation_Date: 2009-10-21   Online_Resource: http://www.nasaspaceflight.com/2009/10/live-atlas-600th-mission-launch-dmsp-f18-vandenberg/   Group: Platform_Logistics      Launch_Date: 2009-10-18      Launch_Site: Vandenberg Air Force Base, USA      Primary_Sponsor: Department of Defense-Department of the Air Force (United States)   End_GroupEnd_Group</skos:definition>

Its pre-launch designation was DMSP 5D-2/S9. This program, previously known as DAPP (Data Acquisition and Processing Program), was classified until March 1973. The objective of this program is to provide global visual and infrared cloudcover data and specialized environmental data to support Department of Defense operational weather analysis and forecasting requirements. Operationally, the program consists of two satellites in sun-synchronous polar orbits, with the ascending node of one satellite in early morning and the other at local noon. The 6.4-m-long spacecraft is separated into four sections: (1) a precision mounting platform for sensors and equipment requiring precise alignment; (2) an equipment support module containing the electronics, reaction wheels, and some meteorological sensors; (3) a reaction control equipment support structure containing the third-stage rocket motor and supporting the ascent phase reaction control equipment; and (4) a 9.29-sq-m solar cell panel. The spacecraft stabilization is controlled by a combination flywheel and magnetic control coil system so sensors are maintained in the desired earth-looking mode. One feature is the precision-pointing accuracy of the primary imager to 0.01 deg provided by a star sensor and an updated ephemeris navigation system. This allows automatic geographical mapping of the digital imagery to the nearest picture element. The operational linescan system is the primary data acquisition system that provides real-time or stored, multi-orbit, day-and-night, visual and infrared imagery of clouds. A supplementary sensor package contains five special sensors: (1) a microwave temperature sounder, (2) an advanced X-ray detector, (3) an ionospheric/scintillation monitor, (4) a precipitating electron/ion spectrometer, and (5) a microwave imager. An infrared temperature and moisture sounder and a magnetometer may also be included on this spacecraft. Either recorded or real-time data are transmitted to ground-receiving sites by two redundant S-band transmitters. Recorded data are read out to tracking sites located at Fairchild AFB, Wash., and at Loring AFB, Maine, and relayed by SATCOM to Air Force Global Weather Central, Offutt AFB, Nebraska. Real-time data are read out at mobile tactical sites located around the world. Additional information concerning this satellite program can be found in the report by D. A.

    <skos:definition xml:lang="en">Meteosat Second Generation (MSG) has been chosen as the name for the new family of Meteorological Satellites. Twenty-five years after the rollout of the first meteorological satellite in 1977, some six other Meteosats later, MSG is now a completely new series of geostationary meteorological satellites with three pieces already being produced and others that may follow within the next decade.MSG is a joint project between ESA and Eumetsat, the organization set up in 1986 to establish, maintain and operate a European system of meteorological satellites. Three satellites are planned at present and a ground segment. ESA is responsible for designing and developing the first satellite - now already in orbit - and for procuring the other three on behalf of Eumetsat. Eumetsat is responsible for defining the payload based on user needs, procuring the ground segment and launchers, and operating the system.With the launch of MSG-2, at any one time, two MSG satellites will be functional in geostationary orbit, the operational one being at 0 degrees longitude which is above equatorial west Africa, the other being on stand-by with 10 degrees of separation.The first satellite, MSG-1 has been launched on board an Ariane 5 launcher inAugust 2002. MSG-2 will follow later. MSG-3 will be built and put in storageuntil it is required to take over as the operational MSG nears the end of itslife. Each satellite will have a nominal seven-year lifetime. A fourth MSGsatellite of the same design is foreseen to ensure continuity of service untilthe end of the next decade.Additional information can be found at &apos;http://www.esa.int/SPECIALS/MSG/&apos;Group: Platform_Details   Entry_ID: MSG   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: METEOSAT      Short_Name: MSG      Long_Name: Meteosat Second Generation   End_Group   Group: Synonymous_Platform_Names      Short_Name: Meteosat-9      Short_Name: Meteosat-8      Short_Name: MSG-1      Short_Name: MSG-2   End_Group   Group: Platform_Associated_Instruments      Short_Name: GERB      Short_Name: SEVIRI   End_Group   Group: Orbit      Orbit_Altitude: 35,800 km      Orbit_Inclination: 0 degrees      Orbit_Type: GEO &gt; Geosynchronous &gt; Geostationary   End_Group   Creation_Date: 2008-07-29   Online_Resource: http://www.esa.int/esaMI/MSG/SEMQSCULWFE_0.html   Group: Platform_Logistics      Launch_Date: 2005-12-25      Launch_Site: Kourou, French Guiana      Design_Life: 7 years      Primary_Sponsor: EUMETSAT   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The Hubble Space Telescope (HST) is a cooperative program of the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) to operate a long-lived space-based  observatory for the benefit of the international astronomical   community. HST is an observatory first dream of in the 1940s,  designed and built in the 1970s and 80s, and operational only in the 1990s. Since its preliminary inception, HST was designed to be a different type of mission for NASA -- a long-term space-based observatory. To accomplish this goal and protect the spacecraft against instrument and equipment failures, NASA had   always planned on regular servicing missions. Hubble has special grapple fixtures, 76 handholds, and stabilized in all three axes. HST is a 2.4-meter reflecting telescope, which was deployed, in low-Earth orbit (600 kilometers) by the crew of the space shuttle Discovery (STS-31) on 25 April 1990.

    <skos:definition xml:lang="en">[Source: National Space Science Data Center, http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1997-012A ]DMSP 5D-2/F14, also named USA 131, is one of a series of meteorological satellites developed and operated by the Air Force under the Defense Meteorological Satellite Program (DMSP). This program, previously known as DAPP (Data Acquisition and Processing Program), was classified until March 1973. The objective of this program is to provide global visual and infrared cloudcover data and specialized environmental data to support Department of Defense operational weather analysis and forecasting requirements. Operationally, the program consists of two satellites in sun-synchronous polar orbits, with the ascending node of one satellite in early morning and the other at local noon.The 6.4-m-long spacecraft is separated into four sections: (1) a precision mounting platform for sensors and equipment requiring precise alignment; (2) an equipment support module containing the electronics, reaction wheels, and some meteorological sensors; (3) a reaction control equipment support structure containing the third-stage rocket motor and supporting the ascent phase reaction control equipment; and (4) a 9.29-sq-m solar cell panel. The spacecraft stabilization is controlled by a combination flywheel and magnetic control coil system so that sensors are maintained in the desired earth-looking mode. One feature is the precision-pointing accuracy of the primary imager to 0.01 deg provided by a star sensor and an updated ephemeris navigation system. This allows automatic geographical mapping of the digital imagery to the nearest picture element.The operational linescan system is the primary data acquisition system and provides real-time or stored, multi-orbit, day-and-night, visual and infrared imagery of clouds. A supplementary sensor package contains: (1) a microwave imager; (2) a microwave temperature sounder; (3) a microwave water vapor profiler; (4) an ion and electron scintillation monitor; (5) a precipitating electron/ion spectrometer; (6) a gamma/X-ray detector; (7) a magnetometer; and (8) a static earth-viewing sensor monitoring electromagnetic radiation.Additional information concerning the satellite can be found in the report by D.

    <skos:definition xml:lang="en">Meteosat-1 was launched in November 1977 and was a geostationaryspacecraft that served as part of European Space Agency&apos;s (ESA)contribution to the Global Atmospheric Research Program (GARP).  Aspart of GARP, the satellite helped to supply data required for globaldata sets used in improvement of machine weather forecasts.  Ingeneral, the spacecraft design, instrumentation, and operation weresimilar to SMS/GOES.  The cylindrically shaped spacecraft measured 210cm in diameter and 430 cm in length, including the apogee boost motor.The primary structural members were an equipment platform and acentral tube. The radiometer telescope was mounted on the equipmentplatform and viewed the earth through a special aperture in the sideof the spacecraft. A support structure extended radially out from thecentral tube and was affixed to the solar panels, which formed theouter walls of the spacecraft and provided the primary source ofelectrical power.  Located in the annulus-shaped space between thecentral tube and the solar panels were station-keeping and dynamicscontrol equipment and batteries. Proper spacecraftattitude and spinrate (approximately 100 rpm) were maintained by jet thrusters mountedon the spacecraft and activated by ground command. The spacecraft usedboth UHF-band and S-band frequencies in its telemetry and commandsubsystems.  A low-power VHF transponder provided telemetry andcommand during launch and then served as a backup for the primarysubsystem once the spacecraft attained synchronous orbit.The spin-stabilized spacecraft carried (1) a visible-IR radiometer toprovide high-quality day/night cloudcover data and to take radiancetemperatures of the earth/atmosphere system, and (2) a meteorologicaldata collection system to disseminate image data to user stations, tocollect data from various earth-based platforms, and to relay datafrom polar-orbiting satellites.  Meteosat-1 was originally placed in ageosynchronous orbit near the prime meridian and was positioned laterbetween 9 and 11 degrees East.For information on the European Space Agency (ESA) and the MeteosatProgram, see the URL: &apos;http://www.esrin.esa.it&apos;----------------Entry taken from:Taken from the NSSDC System for Information Retrieval and Storage (SIRS).

    <skos:definition xml:lang="en">Pioneer 11 was launched on 5 April 1973, like Pioneer 10, on top of anAtlas/Centaur/TE364-4 launch vehicle. After safe passage through the Asteroidbelt on 19 April 1974, the Pioneer 11 thrusters were fired to add another 63.7m/sec (210 ft/sec) to the spacecraft&apos;s velocity. This adjusted the aiming pointat Jupiter to 43,000 km (26,725 miles) above the cloudtops. The close approachalso allowed the spacecraft to be accelerated by Jupiter to a velocity 55 timesthat of the muzzle velocity of a high speed rifle bullet - 173,000 km/hr(108,000 mph) - so that it would be carried across the Solar System some 2.4billion kilometers (1.5 billion miles) to Saturn.During its flyby of Jupiter on 2 December 1974, Pioneer 11 obtained dramaticimages of the Great Red Spot, made the first observation of the immense polarregions, and determined the mass of Jupiter&apos;s moon, Callisto.Looping high above the ecliptic plane and across the Solar System, Pioneer 11raced toward its appointment with Saturn on 1 September 1979. Pioneer 11 flewto within 13,000 miles of Saturn and took the first close-up pictures of theplanet. Instruments located two previously undiscovered small moons and anadditional ring, charted Saturn&apos;s magnetosphere and magnetic field and foundits planet-size moon, Titan, to be too cold for life. Hurtling underneath thering plane, Pioneer 11 sent back amazing pictures of Saturn&apos;s rings. The rings,which normally seem bright when observed from Earth, appeared dark in thePioneer pictures, and the dark gaps in the rings seen from Earth appeared asbright rings.Following its encounter with Saturn, Pioneer 11 explored the outer regions ofour Solar system, studying energetic particles from our Sun (Solar Wind) andcosmic rays entering our portion of the Milky Way. In September 1995, Pioneer11 was at a distance of 6.5 billion km (4 billion miles) from Earth. At thatdistance, it takes over 6 hours for the radio signal (which is traveling at thespeed of light) to reach Earth. However, by September 1995, Pioneer 11 could nolonger make any scientific observations. On 30 September 1995, routine dailymission operations were stopped. Intermittent contact continued until November1995, at which time the last communication with Pioneer 11 took place. Therehave been no communications with Pioneer 11 since. The Earth&apos;s motion hascarried it out of the view of the spacecraft antenna. The spacecraft cannot bemaneuvered to point back at the Earth. It is not known whether the spacecraftis still transmitting a signal. No further tracks of Pioneer 11 are scheduled.

    <skos:definition xml:lang="en">Pioneer 10 was launched on 2 March 1972 on top of an Atlas/Centaur/TE364-4launch vehicle. The launch marked the first use of the Atlas-Centaur as athree-stage launch vehicle. The third stage was required to rocket Pioneer 10to the speed of 51,810 kilometers per hour (32,400 mph) needed for the flightto Jupiter. This made Pioneer the fastest manmade object to leave the Earth,fast enough to pass the Moon in 11 hours and to cross the Mars orbit, about 80million kilometers (50 million miles) away, in just 12 weeks.On 15 July 1972 Pioneer 10 entered the Asteroid Belt, a doughnut shaped areawhich measures some 280 million kilometers wide and 80 million kilometersthick. The material in the belts travels at speed about 20 km/sec. and rangesin size from dust particles to rock chunks as big as Alaska.After safely traversing the Asteroid Belt, Pioneer 10 headed toward Jupiter.Accelerated by the massive giant to a speed of 132,000 km/hr (82,000 mph),Pioneer 10 passed by Jupiter within 130,354 km (81,000 miles) of the cloudtopson December 3, 1973. During the passage by Jupiter, Pioneer 10 obtained thefirst close-up images of the planet, charted Jupiter&apos;s intense radiation belts,located the planet&apos;s magnetic field, and discovered that Jupiter ispredominantly a liquid planet.Following its encounter with Jupiter, Pioneer 10 explored the outer regions ofthe Solar system, studying energetic particles from the Sun (Solar Wind), andcosmic rays entering our portion of the Milky Way. The spacecraft continued tomake valuable scientific investigations in the outer regions of the solarsystem until its science mission ended on March 31, 1997. Since that time,Pioneer 10&apos;s weak signal has been tracked by the DSN as part of an advancedconcept study of communication technology in support of NASA&apos;s futureinterstellar probe mission. The spacecraft had also been used to help trainflight controllers how to acquire radio signals from space during the LunarProspector mission. The power source on Pioneer 10 finally degraded to thepoint where the signal to Earth dropped below the threshold for detection inits latest contact attempt on 7 February, 2003. The previous three contacts hadvery faint signals with no telemetry received. The last time a Pioneer 10contact returned telemetry data was on 27 April 2002.

    <skos:definition xml:lang="en">[Source: National Space Science Data Center, http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1983-113A ]DMSP 5D-2/F7 was one of a series of meteorological satellites developed and operated by the Air Force under the Defense Meteorological Satellite Program (DMSP). This program, previously known as DAPP (Data Acquisition and Processing Program), was classified until March 1973. The objective of this program was to provide global visual and infrared cloudcover data and specialized environmental data to support Department of Defense requirements. Operationally, the program consisted of two satellites in planned 830-km, sun-synchronous polar orbits, with the ascending node of one satellite in early morning and the other one at local noon. The 6.4-m-long spacecraft was divided into four sections: (1) a precision mounting platform for sensors and equipment requiring precise alignment; (2) an equipment support module containing the electronics, reaction wheels, and some meteorological sensors; (3) a reaction control equipment support structure containing the third-stage rocket motor and supporting the ascent phase reaction control equipment; and (4) a 9.29-sq-m solar cell panel. The spacecraft stabilization was controlled by a combination flywheel and magnetic control coil system so sensors were maintained in the desired &apos;earth-looking&apos; mode. One feature was the precision-pointing accuracy of the primary imager to 0.01 deg provided by a star sensor and an updated ephemeris navigation system. This allowed automatic geographical mapping of the digital imagery to the nearest picture element. The operational linescan system was the primary data acquisition system that provided real-time or stored, multi-orbit, day-and-night, visual and infrared imagery of the clouds. A supplementary sensor package contained six special sensors: (1) a microwave temperature sounder, (2) an X-ray spectrometer, (3) an ionospheric plasma monitor, (4) a precipitating electron/ion spectrometer, (5) a magnetometer, and (6) a space radiation dosimeter.

    <skos:definition xml:lang="en">[Source: National Space Science Data Center, http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1977-044A ]DMSP 5D-1/F2 was one of a series of meteorological satellites developed and operated by the Air Force under the Defense Meteorological Satellite Program (DMSP). This program, previously known as DAPP (Data Acquisition and Processing Program), was classified until March 1973. The objectives of this program were to provide global visual and infrared cloud cover data and specialized environmental data to support Department of Defense requirements. Operationally, the program consisted of two satellites in planned 830-km sun-synchronous polar orbits, with the ascending node of one satellite in early morning and the other at local noon. The 5.4-m long spacecraft was separated into four sections: (1) a precision mounting platform (PMP) for sensors and equipment requiring precise alignment, (2) an equipment support module (ESM) containing the electronics, reaction wheels, and some meteorological sensors, (3) a reaction control equipment (RCE) support structure (that has the third-stage motor, hydrazine reaction control system) which supports (4) a 9.29 sq mm solar cell panel. The spacecraft stabilization was controlled by a combination flywheel and magnetic control coil system so sensors could be maintained in the desired `earth-looking&apos; mode. One feature was the precision-pointing accuracy of the primary imager to 0.01 deg provided by a star sensor and an updated ephemeris navigation system. This allowed automatic geographical mapping of the digital imagery to the nearest picture element. The operational line scan system (OLS) built by Westinghouse, was the primary data acquisition system that provided real-time or stored, multi-orbit, day-and-night visual and infrared imagery at 1/3-nautical-mile resolution for all major land masses, 1-1/2-nautical-mile resolution for complete global coverage, and provided with this data calibration, timing, and other auxiliary signals to the spacecraft for digital transmission to the ground. A supplementary sensor package, the special sensor H (SSH), a step-scanning radiometer, was the infrared temperature-humidity-ozone sounder. The data processing system, which included three high-density tape recorders, was capable of storing a total of 400 min of data, each allowing full global coverage twice daily. Either recorded or real-time data were transmitted to ground-receiving sites via two redundant S-band transmitters. Recorded data were read out to tracking sites located at Fairchild AFB, WA, and Loring AFB, ME, and relayed via SATCOM to Air Force Global Weather Central, Offutt AFB, NE. Real-time data were read out at mobile tactical sites located around the world.

    <skos:definition xml:lang="en">Meteosat-P2 (Meteosat 3) was launched on June 15, 1988 from Kourou,French Guiana.  Meteosat 3 is a refurbished protoype of Meteosat-2.In general, the design, the instrumentation, and the operation aresimilar to SMS/GOES.  The cylindrically shaped spacecraft measures 210cm in diameter and 430 cm in length, including the apogee boost motor.The primary structural members are an equipment platform and a centraltube. The radiometer telescope is mounted on the equipment platformand views the earth through a special aperture in the side of thespacecraft.  A support structure extends radially out from the centraltube and is affixed to the solar panels, which form the outer walls ofthe spacecraft. These solar panels provide the primary source ofelectrical power.  Located in the annulus-shaped space between thecentral tube and the solar panels are station-keeping and dynamicscontrol equipment and batteries. Proper spacecraft attitude and spinrate (approximately 100 rpm) are maintained by jet thrusters mountedon the spacecraft and activated by ground command. The spacecraft usesboth UHF-band and S-band frequencies in the telemetry and commandsystems.  During launch, a lower power VHF transponder providestelemetry and command.  After launch, the VHF transponder then servesas a backup for the primary subsystem once the spacecraft attainssynchronous orbit.The spin-stabilized, geostationary spacecraft carries (1) a visible-IRradiometer to provide high-quality, day/night cloud-cover data and totake radiance temperatures of the earth/atmosphere system, and (2) ameteorological data collection system to disseminate image data touser stations, to collect data from various earth-based platforms, andto relay data from polar-orbiting satellites.

The MSG satellites carry an impressive pair of instruments, the Spinning Enhanced Visible and InfraRed Imager (SEVIRI), which has the capacity to observe the Earth in 12 spectral channels and provide image data which is core to operational forecasting needs, and the Geostationary Earth Radiation Budget (GERB) instrument supporting climate studies.More Information: http://www.eumetsat.int/Home/Main/Satellites/MeteosatSecondGeneration/MissionOverview/index.htm?l=enThe Meteosat Third Generation (MTG) system is being established through cooperation between EUMETSAT and the European Space Agency (ESA). ESA has already contributed to the initial research and development of the new satellites. The first MTG-I and MTG-S prototypes are being developed by ESA as part of its MTG programme. The EUMETSAT MTG programme includes the procurement of the four recurrent satellites - three MTG-Is and one additional MTG-S - as well as six launches, the development of the ground segment and the operations of all satellites.The Euronews video (right) provides a useful introduction to past and future developments in European satellite meteorology, with particular reference to the MTG programme.The MTG series will comprise six satellites, with the first spacecraft likely to be ready for launch from 2017. The in orbit configuration will consist of two parallel positioned satellites, the MTG-I (imager) and the MTG-S (sounder) platforms. Unlike the  first and second generation Meteosat series, MTG will be based on three axes stabilised platforms having the advantage that the instruments are 100% of their in orbit time pointed to the Earth.  Such improvements are necessary to achieve compliance with more demanding user requirements on spatial resolution, repeat cycle and signal to noise ratio, and are a prerequisite to conduct soundings from geostationary orbit.MTG-I satellites will fly the Flexible Combined Imager (FCI) and an imaging lightning detection instrument the Lightning Imager (LI). The MTG-S will include an interferometer the InfraRed Sounder (IRS) with hyper-spectral resolution in the thermal spectral domain, and the Sentinel-4 instrument, the high resolution Ultraviolet Visible Near-infrared (UVN) spectrometer.The programme should guarantee access to space-acquired meteorological data until at least the late 2030s.http://www.eumetsat.int/Home/Main/Satellites/MeteosatThirdGeneration/index.htm?l=enGroup: Platform_Details   Entry_ID: METEOSAT   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: METEOSAT      Short_Name: METEOSAT   End_Group   Online_Resource: http://www.eumetsat.int/Home/Main/Satellites/MeteosatFirstGeneration/index.htm?l=en   Online_Resource: http://www.eumetsat.int/Home/Main/Satellites/MeteosatSecondGeneration/MissionOverview/index.htm?l=en   Online_Resource: http://www.eumetsat.int/Home/Main/Satellites/MeteosatThirdGeneration/index.htm?l=en   Group: Platform_Logistics      Launch_Date: 1977-12-09      Primary_Sponsor: ESA      Primary_Sponsor: EUMETSAT   End_GroupEnd_Group</skos:definition>

text: In September 2018 NASA awarded the contract for hosting the MAIA instrument to General Atomics Electromagnetic Systems (GA-EMS). The instrument will fly on the GA-EMS Orbital Test Bed (OTB)-2 satellite. GA-EMS will install the MAIA instrument on their OTB-2 satellite, perform pre-launch testing to prepare the integrated system for operation in space, and operate the satellite once it is launched into Earth orbit. Launch is currently planned for 2022.

The OTB-2 is a larger version of GA-EMS’ OTB-1 spacecraft, which will carry JPL’s Deep Space Atomic Clock into Earth orbit. The larger size and enhanced capabilities of OTB-2 are needed to accommodate the MAIA instrument and its high speed data link. Three deployable solar panels and two additional solar panels attached to the spacecraft body will provide electrical power.

text: The GPS/MET instrument consists of a GPS receiver that has been adoped for space operation. As a low-earth orbiter MET observes the GPS satellites setting behind the Earth&apos;s edge (limb) and the two L-band GPS signals can be used to determine the atmospheric temperature and the ionospheric electron content (along the signal path). The experiment is observing more than one hundred 60-to-100- second-long globally distributed occultations of GPS signals every day. Dual-frequency GPS occultations are extracted from these signals by the orbiting receiver and sent to a ground station where they are processed into different levels of data products.

GPM Constellation is a joint mission with the Japan Aerospace Exploration Agency (JAXA) and other international partners. Building upon the success of the Tropical Rainfall Measuring Mission (TRMM), it will initiate the measurement of global precipitation, a key climate factor. Its science objectives are: to improve ongoing efforts to predict climate by providing near-global measurement of precipitation, its distribution, and physical processes; to improve the accuracy of weather and precipitation forecasts through more accurate measurement of rain rates and latent heating; and to provide more frequent and complete sampling of the Earth&apos;s precipitation. GPM Constellation is envisioned to consist of a core spacecraft to measure precipitation structure and to provide a calibration standard for the constellation spacecraft, an international constellation of NASA and contributed spacecraft to provide frequent precipitation measurements on a global basis, calibration/validation sites distributed globally with a broad array of precipitation-measuring instrumentation, and a global precipitation data system to produce and distribute global rain maps and climate research products.

The GPM Core Observatory carries the first space-borne Ku/Ka-band Dual-frequency Precipitation Radar (DPR) and a multi-channel GPM Microwave Imager (GMI). The DPR instrument, which provides three dimensional measurements of precipitation structure over 78 and 152 mile (125 and 245 km) swaths, consists of a Ka-band precipitation radar (KaPR) operating at 35.5 GHz and a Ku-band precipitation radar (KuPR) operating at 13.6 GHz. Relative to the TRMM precipitation radar, the DPR is more sensitive to light rain rates and snowfall. In addition, simultaneous measurements by the overlapping of Ka/Ku-bands of the DPR can provide new information on particle drop size distributions over moderate precipitation intensities. In addition, by providing new microphysical measurements from the DPR to complement cloud and aerosol observations, GPM is expected to provide further insights into how precipitation processes may be affected by human activities.

The GMI instrument is a conical-scanning multi-channel microwave radiometer covering a swath of 550 miles (885 km) with thirteen channels ranging in frequency from 10 GHz to 183 GHz. The GMI uses a set of frequencies that have been optimized over the past two decades to retrieve heavy, moderate and light precipitation using the polarization difference at each channel as an indicator of the optical thickness and water content.

The GMI uses a set of frequencies that have been optimized over the past two decades to retrieve heavy, moderate and light precipitation using the polarization difference at each channel as an indicator of the optical thickness and water content.Group: Platform_Details   Entry_ID: GPM   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: GPM      Long_Name: Global Precipitation Measurement   End_Group   Group: Platform_Associated_Instruments      Short_Name: GMI      Short_Name: DPR   End_Group   Group: Orbit      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Non-Sun-Synchronous   End_Group   Creation_Date: 2009-02-25   Online_Resource: https://pmm.nasa.gov/GPM   Online_Resource: http://global.jaxa.jp/projects/sat/gpm/index.html   Online_Resource: http://www.eorc.jaxa.jp/GPM/index_e.htm   Group: Platform_Logistics      Launch_Date: 2014-01-25      Launch_Site: TANEGASHIMA ISLAND, JAPAN      Primary_Sponsor: USA/NASA      Primary_Sponsor: JAPAN/JAXA   End_GroupEnd_Group</skos:definition>

Numerous services of high strategic important and economic value are currently being provided based on data from the SPOT or Landsat series of satellites. The lifetime of SPOT-5 and Landsat is coming to an end. It is necessary to provide continuity and thus guarantee the availability of data to service providers and users. Enhancement as required by the growing user demand for higher service quality shall be considered. Action has to be started urgently as recognised also by ESA and EC, including the recent communication to European Parliament on Establishing a GMES Capacity by 2008.In addition, activities related to the accommodation of the IR sensor on Sentinel 2 will be added during the second part of the definition study.

IMAGE is the first satellite missiondedicated to imaging the Earth&apos;s magnetosphere, the region ofspace controlled by the Earth&apos;s magnetic field and containingextremely tenuous plasmas of both solar and terrestrialorigin. Invisible to standard astronomical observing techniques,these populations of ions and electrons have traditionally beenstudied by means of localized measurements with charged particledetectors, magnetometers, and electric fieldinstruments. Instead of such in-situ measurements, IMAGE employsa variety of imaging techniques to &apos;see the invisible&apos; and toproduce the first comprehensive global images of the plasmapopulations in the inner magnetosphere. With these images, spacescientists are able to observe, in a way never before possible,the large-scale dynamics of the magnetosphere and theinteractions among its constituent plasma populations.Additional information available at&apos;http://pluto.space.swri.edu/IMAGE/&apos;Group: Platform_Details   Entry_ID: IMAGE   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: IMAGE      Long_Name: Imager for Magnetopause -to - Aurora Global Exploration   End_Group   Group: Synonymous_Platform_Names      Short_Name: IMAGE   End_Group   Group: Platform_Associated_Instruments      Short_Name: UVI   End_Group   Creation_Date: 2007-11-20   Online_Resource: http://image.gsfc.nasa.gov/   Sample_Image: http://image.gsfc.nasa.gov/image/image_launch_a5.jpg   Group: Platform_Logistics      Launch_Date: 2000-03-25      Launch_Site: Vandenberg Air Force Base, USA      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

text: The MIR deep sea submersibles operate from the RV Akademik Keldysh.

The Akademik Keldysh is the most advanced deep diving support vessel in the world. The operation is owned and operated by the PP Shirshov Institute, Russian Academy of Sciences. Its crew of scientists and technicians have worked together for over 20 years, participating in deep dive expeditions all over the world with both Pisces and MIR submersibles.

Our expedition is only made possible with the support and expertise of Captain Yuriy Gorbach, his Keldysh crew and the MIR support team lead by Dr. Anatoly Sagalevitch. They are a highly skilled, professional team running one of the most unique and safest underwater operations in the world.

The Keldysh and MIR I and II have been used for National Geographic photo and film projects, and director James Cameron&apos;s epic motion picture Titanic. In addition to its 17 laboratories, the Keldysh features a specialized library covering underwater geology, oceanography and deep-sea exploration.

The habitation sphere (pressure hull) of the MIR submersible is 6 feet 10 inches (2.1 meters) in diameter and is specifically designed to carry three people -- in our case one expert pilot and two participants/observers. Inside the sphere it is &quot;one atmosphere,&quot; just like a room in your home. Around the inside of the sphere are many controls, instruments, and electrical circuits. At the forward end of the sphere are three viewports, each providing a forward and a partial peripheral viewing arc. There are two couches/mattresses for the two participants/observers who can lay along these with their faces close to the viewing portholes (you can also sit or stand up to stretch and relax). The pilot sits or kneels at a central control console and guides the submersible using the main central porthole. There is no vision directly to the sides or the aft end of the submersible.

The primary goal of the GRACE mission is to accurately map variations in the Earth&apos;s gravity field over its 5-year lifetime. The GRACE mission has two identical spacecrafts flying about 220 kilometers apart in a polar orbit 500 kilometers above the Earth. 

It maps the Earth&apos;s gravity fields by making accurate measurements of the distance between the two satellites, using geodetic quality Global Positioning System (GPS) receivers and a microwave ranging system. This provides scientists from all over the world with an efficient and cost-effective way to map the Earth&apos;s gravity fields with unprecedented accuracy. The results from this mission yield crucial information about the distribution and flow of mass within the Earth and it&apos;s surroundings.

The gravity variations that GRACE studies include: changes due to surface and deep currents in the ocean; runoff and ground water storage on land masses; exchanges between ice sheets or glaciers and the oceans; and variations of mass within the Earth. Another goal of the mission is to create a better profile of the Earth&apos;s atmosphere. The results from GRACE make a huge contribution to NASA&apos;s Earth science goals, Earth Observation System (EOS) and global climate change studies.

GRACE is a joint partnership between the NASA in the United States and Deutsche Forschungsanstalt fur Luft und Raumfahrt (DLR) in Germany. Dr. Byron Tapley of The University of Texas Center for Space Research (UTCSR) is the Principal Investigator (PI), and Dr. Christoph Reigber of the GeoForschungsZentrum (GFZ) Potsdam is the Co-Principal Investigator (Co-PI). Project management and systems engineering activities are carried out by the Jet Propulsion Laboratory.

The primary goal of the GRACE mission is to accurately map variations in the Earth&apos;s gravity field over its 5-year lifetime. The GRACE mission has two identical spacecrafts flying about 220 kilometers apart in a polar orbit 500 kilometers above the Earth. 

It maps the Earth&apos;s gravity fields by making accurate measurements of the distance between the two satellites, using geodetic quality Global Positioning System (GPS) receivers and a microwave ranging system. This provides scientists from all over the world with an efficient and cost-effective way to map the Earth&apos;s gravity fields with unprecedented accuracy. The results from this mission yield crucial information about the distribution and flow of mass within the Earth and it&apos;s surroundings.

The gravity variations that GRACE studies include: changes due to surface and deep currents in the ocean; runoff and ground water storage on land masses; exchanges between ice sheets or glaciers and the oceans; and variations of mass within the Earth. Another goal of the mission is to create a better profile of the Earth&apos;s atmosphere. The results from GRACE make a huge contribution to NASA&apos;s Earth science goals, Earth Observation System (EOS) and global climate change studies.

GRACE is a joint partnership between the NASA in the United States and Deutsche Forschungsanstalt fur Luft und Raumfahrt (DLR) in Germany. Dr. Byron Tapley of The University of Texas Center for Space Research (UTCSR) is the Principal Investigator (PI), and Dr. Christoph Reigber of the GeoForschungsZentrum (GFZ) Potsdam is the Co-Principal Investigator (Co-PI). Project management and systems engineering activities are carried out by the Jet Propulsion Laboratory.

text: GOES 8 (GOES-I) was launched on April 13, 1994. On Tuesday April 1, 2003 GOES-12 (Formerly Referred to as GOES-M) replaced GOES-8 as the operational GOES East Satellite. NOAA deactivated the satellite on May 5, 2004 and will boost it into an orbit 350 kilometers above its original geostationary position, where it will be disposed safely in three controlled burns. GOES I-M represented the next generation of meteorological satellites and introduces two new features. The first feature, flexible scan, offers small-scale area imaging that lets meteorologists take pictures of local weather trouble spots. This allows them to improve short-term forecasts over local areas. The second feature, simultaneous and independent imaging and sounding, is designed to allow weather forecasters to use multiple measurements of weather phenomena to increase the accuracy of their forecasts. Each satellite in the series carries two major instruments: an Imager and a Sounder. These instruments acquire high resolution visible and infrared data, as well as temperature and moisture profiles of the atmosphere. They continuously transmit these data to ground terminals where the data are processed for rebroadcast to primary weather services both in the United States and around the world, including the global research community. The GOES I-M mission ran from the mid-1990s into the first decade of the 21st century. Each element of the mission has been designed to meet all in-orbit performance requirements for at least five years. The GOES I-M system performed the following basic functions: + Acquisition, processing, and dissemination of imaging and sounding data. + Acquisition and dissemination of Space Environment Monitor (SEM) data. + Reception and relay of data from ground-based Data Collection Platforms (DCPs) that are situated in carefully selected urban and remote areas to the NOAA Command and Data Acquisition (CDA) station. + Continuous relay of Weather Facsimile (WEFAX) and other data to users, independent of all other functions. + Relay of distress signals from people, aircraft, or marine vessels to the search and rescue ground stations of the Search and Rescue Satellite Aided Tracking (SARSAT) system. GOES provides the instantaneous relay functions for the SARSAT system. A dedicated search and rescue transponder on board GOES is designed to detect emergency distress signals originating from Earth-based sources. These unique identification signals are normally combined with signals received by a low-Earth orbiting satellite system and relayed to a search and rescue ground terminal. The combined data are used to perform effective search and rescue operations. The GOES I-M system serves a region covering the central and eastern Pacific Ocean; North, Central, and South America; and the central and western Atlantic Ocean. Pacific coverage includes Hawaii and the Gulf of Alaska. This is accomplished by two satellites, GOES West located at 135 west longitude and GOES East at 75 west longitude. A common ground station, the CDA station located at Wallops, Virginia, supports the interface to both satellites. The NOAA Satellite Operations Control Center (SOCC), in Suitland, Maryland, provides spacecraft scheduling, health and safety monitoring, and engineering analyses. Delivery of products involves ground processing of the raw instrument data for radiometric calibration and Earth location information, and retransmission to the satellite for relay to the data user community.

The multi-element spectral channels simultaneously sweep east-west and west-east along a north-to-south path by means of a two-axis mirror scan system. The instrument can produce full-Earth disc images, sector images that contain the edges of the Earth, and various sizes of area scans completely enclosed within the Earth scene using a new flexible scan system. Scan selection permits rapid continuous viewing of local areas for monitoring of mesoscale (regional) phenomena and accurate wind determination.

    <skos:definition xml:lang="en">GOES 8 (GOES-I) was launched on April 13, 1994. On Tuesday April 1, 2003 GOES-12 (Formerly Referred to as GOES-M) replaced GOES-8 as the operational GOES East Satellite. NOAA deactivated the satellite on May 5, 2004 and will boost it into an orbit 350 kilometers above its original geostationary position, where it will be disposed safely in three controlled burns. GOES I-M represented the next generation of meteorological satellites and introduces two new features. The first feature, flexible scan, offers small-scale area imaging that lets meteorologists take pictures of local weather trouble spots. This allows them to improve short-term forecasts over local areas. The second feature, simultaneous and independent imaging and sounding, is designed to allow weather forecasters to use multiple measurements of weather phenomena to increase the accuracy of their forecasts. Each satellite in the series carries two major instruments: an Imager and a Sounder. These instruments acquire high resolution visible and infrared data, as well as temperature and moisture profiles of the atmosphere. They continuously transmit these data to ground terminals where the data are processed for rebroadcast to primary weather services both in the United States and around the world, including the global research community. The GOES I-M mission ran from the mid-1990s into the first decade of the 21st century. Each element of the mission has been designed to meet all in-orbit performance requirements for at least five years. The GOES I-M system performed the following basic functions: + Acquisition, processing, and dissemination of imaging and sounding data. + Acquisition and dissemination of Space Environment Monitor (SEM) data. + Reception and relay of data from ground-based Data Collection Platforms (DCPs) that are situated in carefully selected urban and remote areas to the NOAA Command and Data Acquisition (CDA) station. + Continuous relay of Weather Facsimile (WEFAX) and other data to users, independent of all other functions. + Relay of distress signals from people, aircraft, or marine vessels to the search and rescue ground stations of the Search and Rescue Satellite Aided Tracking (SARSAT) system. GOES provides the instantaneous relay functions for the SARSAT system. A dedicated search and rescue transponder on board GOES is designed to detect emergency distress signals originating from Earth-based sources. These unique identification signals are normally combined with signals received by a low-Earth orbiting satellite system and relayed to a search and rescue ground terminal. The combined data are used to perform effective search and rescue operations. The GOES I-M system serves a region covering the central and eastern Pacific Ocean; North, Central, and South America; and the central and western Atlantic Ocean. Pacific coverage includes Hawaii and the Gulf of Alaska. This is accomplished by two satellites, GOES West located at 135 west longitude and GOES East at 75 west longitude. A common ground station, the CDA station located at Wallops, Virginia, supports the interface to both satellites. The NOAA Satellite Operations Control Center (SOCC), in Suitland, Maryland, provides spacecraft scheduling, health and safety monitoring, and engineering analyses. Delivery of products involves ground processing of the raw instrument data for radiometric calibration and Earth location information, and retransmission to the satellite for relay to the data user community. The processed data are received at the control center and disseminated to the National Weather Service&apos;s (NWS) National Meteorological Center, Camp Springs, Maryland, and NWS forecast offices, including the National Hurricane Center, Miami, Florida, and the National Severe Storms Forecast Center, Kansas City, Missouri. Processed data are also received by Department of Defense installations, universities, and numerous private commercial users.

Old Value=The first Spacelab mission was a joint NASA and European Space Agency (ESA) mission.  Spacelab 1 consisted of a pressurized compartment (module) for housing equipment and flight personnel and a space-exposed platform to accommodate instruments.  The compartment and platform were flown into space and returned inside the payload compartment of the Space Shuttle.  The mission lasted 10 days, and while in space, the Shuttle payload compartment doors were opened to allow viewing of the earth, sun, and deep space.  Spacelab 1 was a multidiscipline mission comprising five broad areas of investigation: Atmospheric Physics and Earth Observations, Space Plasma Physics, Astronomy and Solar Physics, Material Sciences and Technology, and Life Sciences.  The Atmospheric Physics investigations conducted studies of the earth&apos;s environment through surveys of temperature, composition, and motion of the atmosphere.  The Earth Observations investigations used and evaluated the capability of advanced measuring systems for making topographic and thematic maps from high-resolution photographs and from remote-sensing data.  Investigations in the Space Plasma Physics group studied the charged particle or plasma environment of the earth.  The Astronomy investigations studied astronomical sources of radiation in the ultraviolet and X-ray wavelengths.  The Solar Physics investigations measured the total energy output of the sun using three different methods with the instruments cross calibrated so that meaningful comparisons could be made.  The Material Sciences and Technology investigations took advantage of the microgravity conditions to perform studies in such areas as crystal growth, metallurgy, tribology, fluid physics, and ceramics technology.  The Life Sciences investigations were concerned with the effects of the space environment (zero gravity and high-energy radiation) on human physiology and on the growth, development, and organization of biological systems.  The mission was considered very successful.

text: The ESSA-7 satellite replaced ESSA-5 and provided cloud cover photography to the US&apos;s National Meteorological Center for the purpose of preparing operational weather analyses and forecasts. The spacecraft was an 18-sided polygon, 42 inches in diameter, 22 inches high and weighed 320 pounds. The craft was made of aluminum alloy and stainless steel then covered with 9100 solar cells. The solar cells served to charge the 63 nickel-cadmium batteries.

The two cameras were mounted 180-degrees opposite each other along the side of the cylindrical craft. The &quot;cartwheel&quot; configuration of the TIROS-9 was selected as the orbital configuration of the operational series of ESSA satellites. Therefore, a camera could be pointed at some point on Earth every time the satellite rotated along its axis. The spacecraft operating system was the same as on the TIROS-9. The craft was placed in its planned Sun-synchronous 102-degree inclination retrograde orbit. The satellite spin axis was rotated using the magnetic attitude control system into an alignment perpendicular to the orbital plane and tangent to the Earth&apos;s surface. The ESSA-7 system transmitted images covering 2000-square mile areas with 2-mile resolution from every location once per day. Two arrays of radiometer sensors were also mounted 180-degrees apart to measure the global distribution of solar radiation reflected by the Earth and the Earth&apos;s atmosphere, as well as the long wave emissions from the Earth (a contribution from the NIMBUS program).

text: The LAser GEOdynamic Satellite (LAGEOS) was designed by NASA and launched May 4, 1976. It was the first spacecraft dedicated exclusively to high-precision laser ranging and provided the first opportunity to acquire laser-ranging data that were not degraded by errors originating in the satellite orbit or satellite array. LAGEOS-2, based on the original LAGEOS design, was built by the Italian Space Agency and launched on October 22, 1992.

The LAGEOS satellites are covered with 426 cube corner reflectors with all but four of these reflectors made with fused silica glass. The other four reflectors are made of germanium to obtain measurements in the infrared for experimental studies of reflectivity and satellite orientation.

LAGEOS is a passive satellite with no power, communications, or moving parts. LAGEOS satellite &quot;operations&quot; consists of simply the generation of the orbit predictions necessary for the stations to acquire and track the satellite. Today, these predictions are routinely generated by NASA Goddard Space Flight Center, NERC Space Geodesy Facility, and Japan Aerospace Exploration Agency (JAXA). The predictions are distributed by NASA’s Crustal Dynamics Data Information System (CDDIS) and the EUROLAS Data Center (EDC), data centers supporting the International Laser Ranging Service (ILRS).

text: Weather instruments that collect atmospheric data as they descend after being dropped from research aircraft. These dropwindsondes obtain vertical profiles of wind, temperature, and humidity from 400mb to the surface. This data is then ingested by numerical numerical models to come up with hurricane track and intensity forecasts. These observations provide grid points of observations over the tropical oceans which are generally devoid of weather observations. Aberson and Franklin (1999) state that &quot;accurate modeling of tropical cyclone motion and intensity requires both realistic numerical models and accurate representation of meteorological fields through the depth of the troposphere on a variety of scales.&quot; While models have greatly improved over the past 20 years, significant forecast improvements are still possible by decreasing the analysis error. This has been the primary goal of the Hurricane Research Division (HRD) branch of NOAA. This is wh! y NOAA has procured a new generation of dropwindsondes based on the Global Positioning System (GPS) as well a Gulfstream-IV jet aircraft (G-IV). A study of the impact of the new dropwindsondes&apos; observations on hurricane forecast models was conducted by Aberson and Frankilin in 1997. In the 1997 study about 30 dropwindsondes were used during each mission. These observations were then put into the Geophysical Fluid Dynamics Laboratory (GFDL) and VICBAR hurricane models and the Global Spectral Model (GSM) using the National Center for Environmental Prediction (NCEP) Global Data Assimilation (GDAS). GDAS uses a quality control algorithm, synthetic data and analysis procedures, and the Global Spectral Model in its data assimilation. Further information about the data assimilation can be found in Aberson and Franklin (1999). For the study NCEP&apos;s GSM is run and is used as the boundary conditions for the HRD&apos;s barotropic model (VICBAR) and the GFDL model. The track forecasts of the GSM, VICBAR, and GFDL models were compared to the CLIPER model to calculate track errors and the SHIFOR model to calculate intensity errors.

text: WorldView-4 was an imaging and environment-monitoring satellite from Maxar of the United States, which launched on 11 November 2016 to enhance European Space Imaging&apos;s customer offering with very high-resolution imagery options. Operating in coordination with WorldView-3 and the other satellites of the WorldView constellation, it offered high-resolution imagery at 31 cm resolution in panchromatic mode and 1.23 m in multispectral mode; it provided large area single pass (synoptic) collection, which eliminates temporal variations and offers geolocation accuracy and bi-directional scanning with daily revisits. On 7 January 2019, WorldView-4 was retired when the satellite experienced a failure in its CMGs (Control Moment Gyros), preventing the satellite from collecting imagery due to the loss of an axis of stability.

    <skos:definition xml:lang="en">The Atmospheric Explorer-E (AE-E) spacecraft (Designation: 08440 /75107A) was designed as a multi- sided polyhedron shaped frame with amean diameter of 1.4 meters.  AE-E was similar in construction andinstrumentation to AE-C. AE-E was launched on 1975-11-20 and decayedon 1981-06-10.The purpose of the AE-C mission was to investigate the uppermost layerof the earth&apos;s atmosphere, the thermosphere, with emphasis on energytransfer and other controlling processes.  Photochemical processesrelated to the absorption of solar UV radiation were studied by makingcoordinated measurements of reacting constituents and the solar input.Simultaneous two-spacecraft sampling was carried out at higherlatitudes by the AE-D and AE-E spacecraft until the failure of AE-D onJanuary 29, 1976, and then by (the re-activated) AE-C and AE-Espacecraft until AE-C re-entered the earth&apos;s atmosphere on December12, 1978.The AE-E perigee swept through more than six full latitude cycles andtwo local time cycles during the first year after launch when theorbit was elliptical, and the perigee height was varied between 130and 400 km.  The circularization of the orbit around 390 km was madeon November 20, 1976, and the spacecraft perigee was raised to thisheight whenever it had decayed to about 250 km.  AE-E re-entered theearth&apos;s atmosphere on June 10, 1981 thus terminating the operations.The payload included instrumentation to measure: Solar UV Fluxes, theComposition of Positive Ions and Neutral Particles, the Density andTemperature of neutral particles, positive ions and electrons,Atmospheric airglow emissions, Photoelectron Energy Spectra, Protonand Electron Fluxes with particle energy up to 25 keV, and abackscatter UV spectrometer to monitor the atmospheric ozone content.Power was supplied by a solar cell array.  The spacecraft used a PCMtelemetry data system that operated in real time or using a taperecorder.Group: Platform_Details   Entry_ID: AE-E   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: AE (Atmosphere Explorer)      Short_Name: AE-E      Long_Name: Atmosphere Explorer E (Explorer 55)   End_Group   Group: Synonymous_Platform_Names      Short_Name: Explorer 55      Short_Name: 08440   End_Group   Group: Platform_Associated_Instruments      Short_Name: UV SPECTROMETER   End_Group   Group: Orbit      Perigee: 130 to 400 km   End_Group   Creation_Date: 2007-08-22   Online_Resource: http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1975-107A   Group: Platform_Logistics      Launch_Date: 1975-11-20       Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The THEOS contract with the Thai Ministry of Science and Technology&apos;s Space Agency (GISTDA) includes the production and launch of one optical observation satellite, as well as the development of the ground segment necessary to operate and control the satellite directly from Thailand. This is accompanied by state of the art facilities for image archiving and processing. The THEOS satellite is based on EADS Astrium&apos;s new generation of high performance AstroSat optical Earth observation satellites and benefits from the company&apos;s extensive experience in this field which started with the SPOT and MetOp satellites.As part of the THEOS contract, Thai engineers will join the Astrium development team and attend intensive space programme training. The company firmly believes that this cooperation contract paves the way for further development of GISTDA and space activities in Thailand.The THEOS payload features both high resolution in panchromatic mode (2m) and wide field of view in multi-spectral mode and has been tailored to Thailand&apos;s specific needs with a worldwide imaging capability. It will be launched in 2008 on a sun synchronous orbit at an altitude of around 820km.THEOS will be fully owned and operated by GISTDA and will provide Thailand with worldwide geo-referenced image products and image processing capabilities for applications in cartography, land use, agricultural monitoring, forestry management, coastal zone monitoring and flood risk management. THEOS will provide access to any part of Thailand in less than two days.[Source: EADS Astrium Home Page, http://www.astrium.eads.net/families/daily-life-benefits/remote-sensing/theos ]Group: Platform_Details   Entry_ID: THEOS   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: THEOS      Long_Name: Thai Earth Observation System   End_Group   Group: Platform_Associated_Instruments      Short_Name: MS      Short_Name: PAN   End_Group   Group: Orbit      Orbit_Altitude: 822 km      Orbit_Inclination: 98.7      Equator_Crossing: 10:00 AM      Period: 101.4      Repeat_Cycle: 26      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2008-07-03   Online_Resource: http://www.astrium.eads.net/families/daily-life-benefits/remote-sensing/theos   Online_Resource: http://www.space-risks.com/SpaceData/index.php?id_page=8&amp;Satellite_Name=THEOS   Sample_Image: http://earth.esa.int/earthnetmedia/img/0e/tm_theos.jpg   Group: Platform_Logistics      Launch_Date: 2008-10-01      Launch_Site: Yasny Launch Base, Russia      Primary_Sponsor: Thailand   End_GroupEnd_Group</skos:definition>

Old Value=NASA&apos;s Aura is a mission to understand and protect the air we
breathe. With the launch of Aura NASA has begun to make the most
comprehensive measurements of the Earth&apos;s atmosphere. It also caps off
a 15-year international effort to establish the world&apos;s most
comprehensive Earth Observing System, whose overarching goal is to
determine the extent, causes, and regional consequences of global
change. Aura&apos;s objective is to study the chemistry and dynamics of the
Earth&apos;s atmosphere with emphasis on the upper troposphere and lower
stratosphere (0-30km) by employing multiple instruments on a single
satellite.  The satellite&apos;s measurements enable scientists to
investigate questions about ozone trends, air quality changes and
their linkages to climate change. These observations provide accurate
data for predictive models and provide useful information for local
and national government agencies.

text: In 2017, ESA has chosen two concepts, FORUM and SKIM, to be developed further and compete to be the ninth Earth Explorer mission. Thanks to new technical developments, the FORUM (Far-infrared Outgoing Radiation Understanding and Monitoring) candidate would measure radiation emitted from Earth across the entire far-infrared part of the electromagnetic spectrum. Significantly, it measures in the 15–100 µm range, which has never been done from space before. 1)

These observations are important because Earth emits infrared radiation to space, which is affected by water vapor and cirrus clouds, which, in turn, play key roles in Earth’s temperature.

FORUM’s benchmark measurements would improve our understanding of the greenhouse effect and, importantly, contribute to the accuracy of climate change assessments that form the basis for policy decisions.

    <skos:definition xml:lang="en">[Source: NASA NSSDC, http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1987-022A ]GOES 7 was launched in February 1987 and was a NASA-developed,NOAA-operated, geosynchronous, and operational spacecraft.  The cylindricallyshaped spacecraft measured 190.5 cm in diameter and 230 cm in length, exclusiveof a magnetometer that extended an additional 83 cm beyond the cylinder shell.The primary structural members were a honeycombed equipment shelf and thrusttube.  The VISSR telescope was mounted on the equipment shelf and viewed theEarth through a special aperture in the side of the spacecraft.  A supportstructure extended radially out from the thrust tube and was affixed to thesolar panels, which formed the outer walls of the spacecraft and provided theprimary source of electrical power.  Located in the annulus-shaped spacebetween the thrust tube and the solar panels were stationkeeping and dynamicscontrol equipment, batteries, and most of the SEM equipment.  Proper spacecraftattitude and spin rate (approximately 100 rpm) were maintained by two separatesets of jet thrusters mounted around the spacecraft equator and activated byground command.  The spacecraft used both UHF-band and S-band frequencies inits telemetry and command subsystem.  A low-power VHF transponder providedtelemetry and command during launch and then served as a backup for the primarysubsystem once the spacecraft attained orbit.The spin-stabilized spacecraft carried a visible infrared spin-scan radiometeratmospheric sounder, meteorological data collection and transmission system,space environment monitor, energetic particle monitor, and a magnetic fieldmonitor.  GOES 7 was positioned at 98 degrees West in the summer (Atlantichurricane season) and 108 degrees West in the winter (Pacific storm season).For more information on GOES satellites: http://www.oso.noaa.gov/goes/Group: Platform_Details   Entry_ID: GOES-7   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: GOES (Geostationary Operational Environmental Satellite)      Short_Name: GOES-7      Long_Name: Geostationary Operational Environmental Satellite 7   End_Group   Group: Synonymous_Platform_Names      Short_Name: GOES H      Short_Name: PEACESAT      Short_Name: 17561   End_Group   Group: Platform_Associated_Instruments      Short_Name: SXM      Short_Name: EPM      Short_Name: VAS   End_Group   Group: Orbit      Orbit_Inclination: 0.10000000149011612°      Period: 1440.0 minutes      Perigee: 35788.0 km      Apogee: 35788.0 km      Orbit_Type: GEO &gt; GEOSYNCHRONOUS &gt; GEOSTATIONARY   End_Group   Creation_Date: 2007-10-04   Online_Resource: http://www.oso.noaa.gov/goes/   Online_Resource: http://goespoes.gsfc.nasa.gov/goes/   Online_Resource: http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1987-022A   Sample_Image: http://library01.gsfc.nasa.gov/gdprojs/images/goes_2.jpg   Group: Platform_Logistics      Launch_Date: 1987-02-26      Launch_Site: CAPE CANAVERAL/KENNEDY SPACE CENTER, USA      Primary_Sponsor: USA/NASA      Primary_Sponsor: USA/NOAA   End_GroupEnd_Group</skos:definition>

Developed by Leonardo and SITAEL, PLATiNO-2 TIR will acquire images that will be used to provide valuable services for territories control and protection such as monitoring waters, glaciers, pollutants, state of crops and vegetation, energy consumption in urban areas. PLATiNO-2 is also equipped with the magnetically shielded HT 100, an improved version of SITAEL electric thruster, making PLATiNO-2 one of the first missions in the world to observe the Earth in the Thermal Infrared from a very low orbit – less than 400 km – and thus significantly improving the resolution of the acquired images.

text: The remotely operated vehicle (ROV) Jason 2  is a robotic vehicle tethered to the ship by a fiber optic cable that is capable of working is water depths up to 6500 meters. This tether is only 2.1 cm in diameter and contains 3 copper conductors and 3 single-mode optical fibers. It is incredibly strong with a breaking strength of 18,600 kilograms. Jason is designed to conduct a diverse range of scientific investigations in the world&apos;s oceans. The ROV system also includes the vehicle Medea, which serves as a shock absorber and allows Jason to be decoupled from surface and ship motion. The fiber optic tether runs from the ship to Medea, and then down to Jason, to provide real-time communication to and from the vehicles. When Jason is in the water, it requires three people to operate it: a pilot (who operates the vehicle controls), an engineer (who monitors all of the systems and operates the winch that pays out/hauls in the fiber optic cable attached to Medea), and a navigator (who is responsible for positioning the ship so that the system operates in the desired locations). In addition to these three people during each 4-hour watch, 3 to 5 scientists will also be in the control van working with the Jason crew to accomplish the scientific goals of the cruise.

text: ABOUT THE MTG MISSION:
Severe storms can pose significant and increasing hazards to society. But help is at hand — a new generation of Meteosat satellites will soon be launched, delivering Earth observations of unprecedented range, resolution, and frequency.

Building on the decades-long legacy of Meteosat’s first and second generation satellites, Meteosat Third Generation (MTG) will revolutionise storm prediction, enhance weather forecasts, extend climate records, and provide a wide range of essential observations.

These measurements will underpin services, support livelihoods, and help save lives.

New satellites

MTG is one of the most complex and innovative meteorological geostationary satellite systems ever built. The complete constellation consists of three satellites: two imaging satellites and one sounding satellite, the first operational sounding satellite in a geostationary orbit.

Based on user requirements collected during the planning phase of the programme, MTG will provide near-real-time 3D snapshots of important characteristics of the atmosphere.

MISSION FACTS:
MTG will orbit the Earth at an altitude of 36,000km keeping a constant view over Europe and Africa.
MTG constellation consists of three satellites: two imaging satellites (MTG-I), one sounding satellite (MTG-S). Two constellations of six new geostationary satellites will be launched.
The Infrared Sounder, Lightning Imager and Ultraviolet Visible Near-infrared (UVN) Spectrometer are world firsts in this orbit.
MTG lifetime — MTG-I: 20 years of operational services, MTG-S: 15 years of operational services.
The two MTG-I satellites will operate in tandem, one providing 0 degree full disc service, scanning Europe and Africa every 10 minutes, the other providing the rapid scanning service (RSS), scanning Europe every 2.5 minutes.
MTG-I will deliver more frequent data (full disc every 10 minutes versus 15 minutes currently from MSG and RSS every 2.5 minutes versus 5 minutes), improved spatial resolution (500m/2km versus 1km/3km for MSG) and a better radiometric and spectral resolution (16 channels versus 12 channels for MSG).
The Lightning Imager will provide new real-time data on the location and intensity of lightning flashes in its field of view, covering the full Earth disk.
The infrared and UVN sounding missions will deliver new capabilities for the real-time monitoring of atmospheric profiles, air quality (e.g. tropospheric ozone and carbon monoxide) and dispersion of atmospheric pollution.
MTG carries communications payload (GEOSAR) to relay distress signals from 406MHz emergency beacons to rescue services.
MTG operations will commence following the successful commissioning of the first imaging satellite, MTG-I1 (expected to be one year after launch). The full operational capacity will only be achieved once the first sounder and the second imaging satellite have also been commissioned.
The MTG spacecraft are being built by a European consortium led by Thales Alenia Space of France.
EUMETSAT is responsible for the associated MTG ground segment, which is an integral part of the existing EUMETSAT multi-mission ground network infrastructure, the launch service, the LEOP service and the development of the Satellite Application Facilities part of the MTG programme.

Summary
Mission Capabilities

CBERS-4A has three imaging instruments on board:

    a high-resolution optical imager - Multispectral and Panchromatic Wide-Scan Camera (WPM);
    as well as two different multi-spectral radiometers, a Multispectral Camera (MUX) and a Wide Field Imager (WFI).

The data is used to monitor water resources, agriculture, urban growth and land use, with a large focus on controlling the deforestation and burning of the Amazon rainforest. The addition of CBERS-4A to the satellites observing Brazil is beneficial due to the high frequency of clouds in the Amazon region; the more satellites observing the area, the higher the chance of uninterrupted images. The data collected will be of large use to the national programs of Brazil, Prodes (measurement of deforestation by remote sensing) and Deter (Brazilian real-time deforestation detection).
Performance Specifications

All three instruments measure over three visible bands (blue, green, red) and one near infrared (NIR) band. WPM also observes over one panchromatic band with a spatial resolution of 2 m, and a resolution of 8 m for the visible and NIR bands. It has a swath width of 92 km. MUX has a resolution of 16 m and a swath width of 95 km, while WFI has a resolution of 55 m and a swath width of 684 km.

CBERS-4A undertakes a sun-synchronous orbit with an altitude of 629 km and an inclination of 97.9°. The satellite has a period of 97.3 minutes and a repeat cycle of 31 days.
Space and Hardware Components

The 1,730 kg satellite CBERS-4A was launched onboard a Long March 4B (LM-4B) launch vehicle from the Taiyuan Satellite Launch Complex in Shanxi, China.

    <skos:definition xml:lang="en">The  Combined  Release and Radiation Effects Satellite (CRRES) Programis  comprised of several elements.  One is the release of powdered andliquid chemicals during the first 45 to 60 days after launch, when thespacecraft  is  in its 300-km altitude circular orbit.  These releasesare  used to study electric fields, neutral winds, and other phenomenain  the  upper atmosphere, the ionosphere, and the magnetosphere.  Thespacecraft  spins at 20 rpm during the low altitude orbit phase of theprogram.   After the chemical releases are completed, the satellite isboosted  into  a geosynchronous-transfer-type orbit and spun down to 2rpm.   The orbit parameters of this final orbit are as follows: apogeealtitude  -  35,800  km,  perigee altitude - 400 km, period - 630 min,inclination  -  about  16  deg.As  the  satellite  traverses  the  inner  magnetosphere,   a     fullcomplement   of   field,  particle,  and  plasma instruments  measuresthe  radiation  environment.  A comprehensive set of  state-of-the-artmicroelectronics  devices  and  other spacecraft components are testedin  orbit for radiation effects.  A major segment of the CRRES payloadis  part  of  AFGL&apos;s Space Radiation Effects Program (SPACERAD).   TheSPACERAD  Program  is a comprehensive space and ground test  effort to(a)  measure  radiation-induced  single  event  upsets and total  dosedegradation  of state-of-the-art  microelectronics  devices, includingVHSIC  and  GaAs, in a known space environment; (b) perform laboratoryradiation response and annealing  characterization  of parts identicalto  those  flown  on  CRRES;  (c)  develop algorithms to relate  spaceperformance   of   microelectronic   components   to    ground    testprocedures,  and  update  existing radiation ground test guidelines tomore  accurately  simulate the behavior of devices in space; (d) spacequalify  advanced  technology  devices for use in operational systems;(e)  update  the static models of the radiation belts; and (f) developthe first dynamic models of the high-energy particle populations.  Theon-orbit  phase  of  SPACERAD  lasts  for about 3 years.  In addition,there  are  other  radiation belt experiments on CRRES provided by theNavy.   The  CRRES spacecraft has the shape of an octagonal prism withsolar  arrays  on the top side.  The prism is 1 m high and 3 m betweenopposite  faces.   Four of the eight compartments are for the chemicalcanisters and the other four house the SPACERAD and other experiments.The  spin axis of CRRES is controlled so that it points at the sun.

    <skos:definition xml:lang="en">- Spacecraft Brief Description -The two primary goals of this satellite were to minimize the effects ofnon-gravitational forces and to obtain the highest possible accuracy for laserrange measurements. The satellite was spherically shaped with a 12-cm radius.The core was an alloy of uranium 238 and 1.5% molybdenum. The skin consisted of20 spherical caps made of an alloy of aluminum and 5% magnesium with triangularbases. Each cap contained three laser corner cubes. The corner cubes were fusedsilica trihedrons with circular apertures made of suprasil 1 with silvercoatings covered by inconel. For Groupe de Recherches de Geodesie Spatiale(GRGS), the principal objective was to study earth and ocean tides by (1) thedetermination of the second harmonics (amplitude and phase) of the mainsemidiurnal oceanic tides (M and S) and, if possible, of the diurnal K, O, andP tides; and (2) the determination of the dissipation in the solid earth and inthe oceans (Q).                  - Auxiliary Information -    Launch Date and Time :  1975-02-06    Epoch Date and Time  :  1975-02-20    Apogee (km or AU):      1108.

text: PlanetiQ was founded to build, launch, and operate a commercial constellation of the highest quality HD GNSS-RO weather satellites, with a full constellation of 20 Low Earth Orbit (LEO) satellites. PlanetiQ’s GNSS Navigation and Occultation Measurement Satellites (GNOMES) carry the fourth-generation “Pyxis” radio occultation (RO) sensor which builds on the heritage of the gold standard for RO sensors. This state-of-the-art, next-generation RO sensor is smaller, lighter, and consumes less power than prior versions, but has nearly 3x the data collection capability since it receives signals from all four world-wide GNSS constellations (GPS, GLONASS, Galileo and Beidou).

    <skos:definition xml:lang="en">PlanetiQ was founded to build, launch, and operate a commercial constellation of the highest quality HD GNSS-RO weather satellites, with a full constellation of 20 Low Earth Orbit (LEO) satellites. PlanetiQ’s GNSS Navigation and Occultation Measurement Satellites (GNOMES) carry the fourth-generation “Pyxis” radio occultation (RO) sensor which builds on the heritage of the gold standard for RO sensors. This state-of-the-art, next-generation RO sensor is smaller, lighter, and consumes less power than prior versions, but has nearly 3x the data collection capability since it receives signals from all four world-wide GNSS constellations (GPS, GLONASS, Galileo and Beidou).</skos:definition>

Old Value=ERBS was part of the NASA&apos;s 3 satellite Earth Radiation Budget Experiment
(ERBE), designed to investigate how energy from the Sun is absorbed and
re-emitted by the earth. This process of absorption and re-radiation is one of
the principal drivers of the Earth&apos;s weather patterns. Observations from ERBS
are also used to determine the effects of human activities (such as burning
fossil fuels and the use CFCs) and natural occurrences (such as volcanic
eruptions) on the Earth&apos;s radiation balance. In addition to the ERBE scanning
and nonscanning instruments, the satellite also carried the Stratospheric
Aerosol Gas Experiment (SAGE II).

The ERBS was the first of three ERBE platforms which would eventually carry the
ERBE Instruments. Goddard Space Flight Center built the satellite and it was
launched by the Space Shuttle Challenger in 1984. The second ERBE Instrument
was aboard the NOAA-9 satellite when it was launched in January of 1985, and
the third was aboard the NOAA-10 satellite when it was launched in October of
1986. Although the scanning instruments on board all three ERBE satellites are
no longer operational, the nonscanning instruments are all presently
functioning.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

Old Value=Terra is the flagship satellite of NASA&apos;s Earth observing systems. Terra is the first EOS (Earth Observing System) platform and provides global data on the state of the atmosphere, land, and oceans, as well as their interactions with solar radiation and with one another.

Since the 1950&apos;s, it has become increasingly clear that human activities are modifying the composition of the atmosphere on a global scale. As the result of industrialization, the concentration of carbon dioxide has increased by about 20% during this period. More recently, the stratospheric concentrations of chemically-active gases containing chlorine, bromine, and fluorine have dramatically increased. These trends have created issues of global interest including global warming and declining levels of ozone (both globally and in the ozone &amp;hole&amp; in the Antarctic). It has become increasingly clear, however, that these processes do not occur independently of one another and can only be understood in the context of a global system. Accurate and precise measurements are needed to unravel complex and interactive relationships between chemical, radiative, and dynamical processes in the atmosphere, ocean, and on land. As a result, in 1991 NASA initiated a comprehensive program to understand the Earth&apos;s atmosphere, oceans, land, and cryosphere (ice and snow) as a single, complex, interactive system. NASA&apos;s Earth Observing System (EOS) consists of a series of spaceborne instruments to monitor crucial components of the Earth system, an advanced data handling system, and teams of scientists who will evaluate on-going climate change and predict future changes. Ultimately, EOS will produce scientifically sound recommendations for environmental policy to national and international bodies to mitigate or prepare for these changes.

Old Value=Terra is the flagship satellite of NASA&apos;s Earth observing
systems. Terra is the first EOS (Earth Observing System) platform and provides
global data on the state of the atmosphere, land, and oceans, as well as their
interactions with solar radiation and with one another.

Since the 1950&apos;s, it has become increasingly clear that human activities are
modifying the composition of the atmosphere on a global scale. As the result of
industrialization, the concentration of carbon dioxide has increased by about
20% during this period. More recently, the stratospheric concentrations of
chemically-active gases containing chlorine, bromine, and fluorine have
dramatically increased. These trends have created issues of global interest
including global warming and declining levels of ozone (both globally and in
the ozone &amp;hole&amp; in the Antarctic). It has become increasingly clear, however,
that these processes do not occur independently of one another and can only be
understood in the context of a global system. Accurate and precise measurements
are needed to unravel complex and interactive relationships between chemical,
radiative, and dynamical processes in the atmosphere, ocean, and on land. As a
result, in 1991 NASA initiated a comprehensive program to understand the
Earth&apos;s atmosphere, oceans, land, and cryosphere (ice and snow) as a single,
complex, interactive system. NASA&apos;s Earth Observing System (EOS) consists of a

system, an advanced data handling system, and teams of scientists who will
evaluate on-going climate change and predict future changes. Ultimately, EOS

New Value=Terra is the flagship satellite of NASA&apos;s Earth observing
systems. Terra is the first EOS (Earth Observing System) platform and provides
global data on the state of the atmosphere, land, and oceans, as well as their
interactions with solar radiation and with one another.

Since the 1950&apos;s, it has become increasingly clear that human activities are
modifying the composition of the atmosphere on a global scale. As the result of
industrialization, the concentration of carbon dioxide has increased by about
20% during this period. More recently, the stratospheric concentrations of
chemically-active gases containing chlorine, bromine, and fluorine have
dramatically increased. These trends have created issues of global interest
including global warming and declining levels of ozone (both globally and in
the ozone &amp;hole&amp; in the Antarctic). It has become increasingly clear, however,
that these processes do not occur independently of one another and can only be
understood in the context of a global system. Accurate and precise measurements
are needed to unravel complex and interactive relationships between chemical,
radiative, and dynamical processes in the atmosphere, ocean, and on land. As a
result, in 1991 NASA initiated a comprehensive program to understand the
Earth&apos;s atmosphere, oceans, land, and cryosphere (ice and snow) as a single,
complex, interactive system. NASA&apos;s Earth Observing System (EOS) consists of a
series of spaceborne instruments to monitor crucial components of the Earth
system, an advanced data handling system, and teams of scientists who will
evaluate on-going climate change and predict future changes. Ultimately, EOS
will produce scientifically sound recommendations for environmental policy to
national and international bodies to mitigate or prepare for these changes.

Old Value=Set for launch in 2018, ADM-Aeolus (or just &apos;Aeolus&apos;), is the fourth Earth Explorer mission to be developed within ESA&apos;s Living Planet Programme. Aeolus will be the first-ever satellite to directly observe wind profiles from space. 

Named after Aeolus, who in Greek mythology was appointed &apos;keeper of the winds&apos; by the Gods, this mission will provide much-needed data to improve the quality of weather forecasts as well as contribute to long-term climate research.
New Value=The Earth Explorer Atmospheric Dynamics Mission Aeolus will provide global observations of wind profiles from space to improve the quality of weather forecasts, and to advance our understanding of atmospheric dynamics and climate processes.

Although there are several ways of measuring wind from a satellite, Aeolus will utilise the active Doppler Wind Lidars (DWL) method. This is the only method that has the potential to provide the required data globally, from direct wind observations. In addition, a DWL will provide information on cloud top heights, vertical distribution of cloud, aerosol properties, and wind variability. This information is a useful by-product of the DWL method.

An improved model of the Earth&apos;s climate and atmosphere will lead to progress in numerical weather prediction (NWP), especially concerning long-term forecasting. It is widely recognised that a new global atmospheric observing system, such as Aeolus, will have a great effect upon operational weather forecasting. The provision of detailed wind profiles will also benefit scientists involved with climate research, allowing for greater accuracy in the numerical modelling of tropical regions in particular. 

The Aeolus mission was launched on 22 August 2018.</skos:changeNote>

text: In 1996, Korea established its long-term plan of the National Space Program which was revised in 2000 to accommodate the public and civilian demand for satellite utilization and to maintain the continuity of satellite services. The plan prospects the details of the future space activities of Korea until 2015 and serves as a basis for space development in Korea. In response to this space plan, the Korea Meteorological Administration (KMA) started to define and formulate the basic requirements for COMS, the first geostationary meteorological satellite mission of Korea. - Note: The nickname Cheollian means long distance view (literally &quot;Thousand Li View&quot;) in Korean.

COMS is a geostationary meteorological satellite program of Korea with multifunctional applications in the fields of:

1) Experimental communications: a) in-orbit verification of developed communication technology, b) experiment of wide-band multimedia communication service

2) Ocean color monitoring: a) monitoring of marine environment and ecosystem, b) production of fishery information. The scope of the ocean color mission includes detecting, monitoring and predicting short-term biological phenomena such as HAB (Harmful Algal Bloom), studies on biogeochemical variables, monitoring health of the marine ecosystem, coastal zone and resource management and providing information for fishing communities.

3) Meteorological observations: a) continuous monitoring of the ground segment from GEO and extraction of meteorological products, b) early detection of severe weather phenomena, c) monitoring of long-term change of SST and clouds. The meteorological mission will complement the existing network of geostationary satellites, providing improved input data for numerical weather prediction models, and monitoring climate changes; the data, imagery and derived products will be freely available to both domestic and international community in real-time or near real-time basis through direct broadcasting or land lines.

text: Responding to the ever-growing demand for environmental information, the National Oceanic and Atmospheric Administration (NOAA) seeks to enter into contracts to purchase Global Navigation Satellite System (GNSS) radio occultation (RO) observations produced by commercial vendors at a low-cost. GeoOptics is one commercial vendor awarded a contract with NOAA. GeoOptics operates the Community Initiative for Cellular Earth Remote Observation (CICERO) constellation of low-earth-orbiting (LEO) 6U CubeSats. The 6U-sized CICERO will enable the deployment of GNSS array consisting of RO satellites in the Earth’s atmosphere to obtain many atmospheric observations which can improve weather forecasting. Applying GeoOptics RO data to reliable weather forecasting requires an assessment of its performance. This study analyzes the performance of GeoOptics CubeSats measurements by comparing it with the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) missions (COSMIC-1 and COSMIC-2). The performance analysis was carried on data coverage capabilities and measurement quality. The analysis of data coverage confirmed that GeoOptics can acquire global observational coverage with adequate low-altitude penetration capability, while there should be updated in local time coverage. The analysis of RO measurement quality showed that GeoOptics RO measurements are comparable to those of COSMIC-2, even though GeoOptics exhibited a lower signal-to-noise ratio (SNR). The potential of GeoOptics allows for the development of a GNSS array in the Earth’s atmosphere and a large amount of effective RO measurements to be obtained for reliable weather forecasting.

Old Value=The Ocean Surface Topography Mission (OSTM)/Jason-2 was a follow-on altimetric mission to the very successful TOPEX/Poseidon 
mission and Jason-1. It was a joint mission between NASA and CNES (French space agency). It launched 20 June 2008 and began 
data collection on 12 July 2008. OSTM measured significant wave height, sigma naught (sigma0), dry and wet troposphere and 
ionosphere, which can be used to calculate sea surface height and anomalies and total electron content.

Old Value=The Tropical Rainfall Measuring Mission (or TRMM) is a NASA satellite that provides more information both to test and to improve those models. TRMM is particularly devoted to determining rainfall in the tropics and subtropics of the Earth. These regions make up about two thirds of the total rainfall on Earth and are responsible for driving our weather and climate system. TRMM contributed to a better understanding of where and how much the winds blow, where the clouds form and rain occurs, where floods and droughts will occur, and how the winds drive the ocean currents. TRMM accomplished this not just by providing rainfall data but, more importantly, by providing information on heat released into the atmosphere as part of the process that leads to rain.

TRMM was launched on November 27, 1997, on the Japanese H-II vehicle from the Tanegashima Space Center in Tanegashima, Japan. Continuous science data collection began December 8, 1997. Upon completion of the nominal 3-year prime mission, the decision was made to boost the mission from its original altitude of 350km to 402.5km, to reduce fuel consumption and extend the mission life. The TRMM boost was completed August 24, 2001, and the orbit was maintained until 2014, when fuel was depleted and the spacecraft began to descend. Mission operations were terminated in April 2015, the spacecraft re-entered the Earth’s atmosphere and mostly burned up in June 2015.

TRMM exceeded its 3-year design goal by collecting 17 years of rainfall data, creating a benchmark rainfall climatology which is used to test, compare and improve global climate models. The TRMM dataset of rain distribution across the tropics has narrowed considerably the range of uncertainty in previous space-based rainfall estimates. The choice of a precessing, low-inclination orbit (35°) enabled the quantification of the diurnal cycle of precipitation and convective intensity over land and ocean tropics-wide on fine scales (0.25°). TRMM products have provided the first comprehensive estimates of how rainfall is directly related to latent heat release in the atmosphere, a key characteristic in understanding the impact of tropical rainfall on the general circulation of the atmosphere. Based on hydrometeor vertical structure information from the TRMM active and passive sensors, TRMM produced climatologies of latent heating profiles for analysis and comparison with global models. In addition, the lightning sensor delivered a detailed global map of lightning distribution, and combined with the rain data, led to quantifying the lightning/convection relation for land and ocean.

The choice of a precessing, low-inclination orbit (35°) enabled the quantification of the diurnal cycle of precipitation and convective intensity over land and ocean tropics-wide on fine scales (0.25°). TRMM products have provided the first comprehensive estimates of how rainfall is directly related to latent heat release in the atmosphere, a key characteristic in understanding the impact of tropical rainfall on the general circulation of the atmosphere. Based on hydrometeor vertical structure information from the TRMM active and passive sensors, TRMM produced climatologies of latent heating profiles for analysis and comparison with global models. In addition, the lightning sensor delivered a detailed global map of lightning distribution, and combined with the rain data, led to quantifying the lightning/convection relation for land and ocean.

New Value=The Tropical Rainfall Measuring Mission (or TRMM) is a NASA satellite that provides more information both to test and to improve those models. TRMM is particularly devoted to determining rainfall in the tropics and subtropics of the Earth. These regions make up about two thirds of the total rainfall on Earth and are responsible for driving our weather and climate system. TRMM contributed to a better understanding of where and how much the winds blow, where the clouds form and rain occurs, where floods and droughts will occur, and how the winds drive the ocean currents. TRMM accomplished this not just by providing rainfall data but, more importantly, by providing information on heat released into the atmosphere as part of the process that leads to rain.

TRMM was launched on November 27, 1997, on the Japanese H-II vehicle from the Tanegashima Space Center in Tanegashima, Japan. Continuous science data collection began December 8, 1997. Upon completion of the nominal 3-year prime mission, the decision was made to boost the mission from its original altitude of 350km to 402.5km, to reduce fuel consumption and extend the mission life. The TRMM boost was completed August 24, 2001, and the orbit was maintained until 2014, when fuel was depleted and the spacecraft began to descend. Mission operations were terminated in April 2015, the spacecraft re-entered the Earth’s atmosphere and mostly burned up in June 2015.

The Gravity Recovery and Climate Experiment Follow-on (GRACE-FO) mission is a partnership between NASA and the German Research Centre for Geosciences (GFZ). GRACE-FO is a successor to the original GRACE mission, which began orbiting Earth on March 17, 2002. GRACE-FO will carry on the extremely successful work of its predecessor while testing a new technology designed to dramatically improve the already remarkable precision of its measurement system.

GRACE-FO, scheduled for launch in early 2018, will continue the work of tracking Earth&apos;s water movement to monitor changes in underground water storage, the amount of water in large lakes and rivers, soil moisture, ice sheets and glaciers, and sea level caused by the addition of water to the ocean. These discoveries provide a unique view of Earth&apos;s climate and have far-reaching benefits to society and the world&apos;s population.

The Gravity Recovery and Climate Experiment Follow-on (GRACE-FO) mission is a partnership between NASA and the German Research Centre for Geosciences (GFZ). GRACE-FO is a successor to the original GRACE mission, which began orbiting Earth on March 17, 2002. GRACE-FO will carry on the extremely successful work of its predecessor while testing a new technology designed to dramatically improve the already remarkable precision of its measurement system.

GRACE-FO, scheduled for launch in early 2018, will continue the work of tracking Earth&apos;s water movement to monitor changes in underground water storage, the amount of water in large lakes and rivers, soil moisture, ice sheets and glaciers, and sea level caused by the addition of water to the ocean. These discoveries provide a unique view of Earth&apos;s climate and have far-reaching benefits to society and the world&apos;s population.

    <skos:definition xml:lang="en">Mission Objectives:The Zeya satellite is a Russian Military Communicationssatellite launched on March 4, 1997. Zeya is named after theZeya River, which is very close to it&apos;s launch site, CosmodromeSvobodniy. This was the first satellite launched from this newRussian launch site in far eastern Russia.  Note: Sometimes alsospelled Zeia.ILRS Mission Support Status: Satellite laser ranging was usedfor precision orbit determination for this spacecraft and usedfor calibration of GPS and GLONASS navigation equipment aboardthe satellite. This satellite was only tracked for 6 months bythe international laser ranging network. SLR tracking supportwas discontinued on 29 July 1997.Instrumentation:  Zeya has the following instrumentation onboard:1) Radio equipment2) GPS receiver3) GLONASS receiver4) Laser retroreflector arrayRetroReflector Array (RRA) Characteristics: The retro-reflectorarray is a box array of 20 corner cubes, which are optimized at532 nanometers. Twenty retroreflectors operating with principle&apos;not more than one reflectors works in any direction&apos; areinstalled on the satellite. Each retroreflector has field ofview of 35 arc degrees. Retroreflectors ensure reflection oflaser light within 47% of 4 steradian. Satellite&apos;s designprovides accuracy of link of range measurements to the center ofmass with root mean square error of about 5 mm. Systematiccorrection is 419 mm. The satellite is spinning around Y axiswith angular velocity about 30 revolutions per minute.Additional information available at&apos;http://ilrs.gsfc.nasa.gov/satellite_missions/list_of_satellites/zeya/&apos;[Summary provided by NASA]</skos:definition>

    <skos:definition xml:lang="en">Dropwindsondes are weather instruments that collect atmospheric data as they descend after being dropped from research aircraft.  These dropwindsondes obtain vertical profiles of wind, temperature, and humidity from 400mb to the surface. This data is then ingested by numerical numerical models to come up with hurricane track and intensity forecasts.  These observations provide grid points of observations over the tropical oceans which are generally devoid of weather observations.  Aberson and Franklin (1999) state that &apos;accurate modeling of tropical cyclone motion and intensity requires both realistic numerical models and accurate representation of meteorological fields through the depth of the troposphere on a variety of scales.&apos;  While models have greatly improved over the past 20 years, significant forecast improvements are still possible by decreasing the analysis error.  This has been the primary goal of the Hurricane Research Division (HRD) branch of NOAA.  This is wh!  y NOAA has procured a new generation of dropwindsondes based on the Global Positioning System (GPS) as well a Gulfstream-IV jet aircraft (G-IV).  A study of the impact of the new dropwindsondes&apos; observations on hurricane forecast models was conducted by Aberson and Frankilin in 1997. In the 1997 study about 30 dropwindsondes were used during each mission.  These observations were then put into the Geophysical Fluid Dynamics Laboratory (GFDL) and VICBAR hurricane models and the Global Spectral Model (GSM) using the National Center for Environmental Prediction (NCEP) Global Data Assimilation (GDAS).  GDAS uses a quality control algorithm, synthetic data and analysis procedures, and the Global Spectral Model in its data assimilation.  Further information about the data assimilation can be found in Aberson and Franklin (1999). For the study NCEP&apos;s GSM is run and is used as the boundary conditions for the HRD&apos;s barotropic model (VICBAR) and the GFDL model.  The track forecasts of the GSM, VICBAR, and GFDL models were compared to the CLIPER model to calculate track errors and the SHIFOR model to calculate intensity errors.  The CLIPER and SHIFOR models are statistical regression models which use only climatology and persistence in their forecasts.

text: The National Polar-orbiting Operational Environmental Satellite System (NPOESS) was a joint program of the Air Force, NOAA, and NASA. Its polar-orbiting satellites were to provide long-term systematic measurements of key environmental variables for weather forecasting as well as climate studies. In February 2010, NPOESS was split into two programs. The Air Force-managed component will build satellites for the morning orbit, serving military needs. The NASA-managed civilian component, called the Joint Polar Satellite System (JPSS), will build satellites to fly in afternoon orbits, and will be operated by NOAA.

text: The Haiyang-2 (HY-2) satellite series is a second generation ocean observation satellite, managed by the China National Space Administration (CNSA) and the Chinese Academy of Space Technology (CAST). It is the follow-on mission to the first generation, HY-1A and HY-1B. HY-2’s primary objective was to measure ocean dynamic and regional environmental trends in the microwave spectral range. Further, parameters such as marine wind vector, marine surface heat and Sea Surface Temperature (SST) aid aero-marine forecasts for the prevention of, and relief in the event of, natural disasters. The first Haiyang satellite, HY-2A, was launched in August 2011, producing observational data until its service was terminated in December 2021. The satellite series consists of eight satellites with four currently in operation and four more planned to be launched by 2025.

text: The Japanese Geostationary Meteorological Satellite (GMS) series, also known as its nickname, &quot;Himawari&quot; (meaning a &quot;sunflower&quot;), is on the geostationary orbit at 140 degrees of east longitude to carry out weather observation from space being part of the World Weather Watch (WWW) project of the World Meteorological Organization. The images of the earth and clouds sent from this satellite series have been used in many areas such as weather forecasts in TV or newspaper; therefore, it is strongly connected to our daily life.
After the &quot;Himawari-6&quot;, the GMS series was replaced by a Multifunctional Transport Satellite series to broaden its scope of operation. It is operated by the Japan Meteorological Agency for climatic observation.

Old Value=Aqua is a major international Earth Science satellite mission centered at NASA. Launched on May 4, 2002, the satellite has six different Earth-observing instruments on board and is named for the large amount of information being obtained about water in the Earth system from its stream of approximately 89 Gigabytes of data a day. The water variables being measured include almost all elements of the water cycle and involve water in its liquid, solid, and vapor forms. Additional variables being measured include radiative energy fluxes, aerosols, vegetation cover on the land, phytoplankton and dissolved organic matter in the oceans, and air, land, and water temperatures.

    <skos:definition xml:lang="en">Spacecraft Brief Description  The  PAGEOS (Passive Geodetic Earth Orbiting Satellite) spacecraft was  a  30.48-m inflatable sphere, and had no instrumentation on board.  It  was  the  second  (following  GEOS  1)  NASA satellite in the National  Geodetic  Satellites  Program.  PAGEOS 1 was made up of 84 gores and 2  pole  caps  of  0.0127-mm  aluminized mylar film.  The gores were 48 m  long  with  maximum  width  of 1.24 m and the pole caps were 1.02 m in  diameter.   The  primary  purpose  of  the  satellite was to provide a  tracking  target for geodetic purposes.  It had a specular reflectance  of  0.862,  and a diffuse reflectance of 0.029, providing a reflecting  light   source   whose   brightness   was  relatively  independent  of  observer-satellite-sun   phase   angle.   The  surface  was  also  97%  reflectant  for microwave energy in the range from 17 to 4E5 kHz.  The  launch,  orbit,  separation,  inflation  and  initial  operation  were  nominal,  with  more  than  40  ground  stations  participating in the  observation  program.  The orbit was generally considered too high for  drag-density  study,  although  some work was done in this area by the  Smithsonian   Astrophysical   Observatory.

    <skos:definition xml:lang="en">- Spacecraft Brief Description -Vanguard 2 was an earth-orbiting satellite designed to measurecloud-cover distribution over the daylight portion of its orbit. Thespacecraft was a 9.8 kg magnesium sphere 50.8 cm in diameter. Itcontained two optical telescopes with two photocells. The sphere wasinternally gold-plated and externally covered with an aluminum depositcoated with silicon oxide of sufficient thickness to provide thermalcontrol for the instrumentation. Radio communication was provided by a1-W, 108.03-MHz telemetry transmitter and a 10-mW, 108-MHz beacontransmitter that sent a continuous signal for tracking purposes. Acommand receiver was used to activate a tape recorder that relayedtelescope experiment data to the telemetry transmitter. Bothtransmitters functioned normally for 19 days. The satellite was spinstabilized at 50 rpm, but telemetry data were poor because of anunsatisfactory orientation of the spin axis. The power supply for theinstrumentation was provided by mercury batteries.                  - Auxiliary Information -    Launch Date and Time :  1959-02-17 16:05:00    Epoch Date and Time  :  1959-02-17 16:48:00    Apogee (km or AU):      3320.

Inclination (degree) :  32.88    Orbit Type :            Geocentric    Information last updated on 1992-04-14Vanguard 3 was launched by a Vanguard rocket from the Eastern TestRange into a geocentric orbit. The objectives of the flight were tomeasure the earth&apos;s magnetic field, the solar X-ray radiation and itseffects on the earth&apos;s atmosphere, and the near-earth micrometeoroidenvironment. Instrumentation included a proton magnetometer, X-rayionization chambers, and various micrometeoroid detectors. Thespacecraft was a 50.8-cm-diameter magnesium sphere. The magnetometerwas housed in a glass fiber phenolic resin conical tube attached tothe sphere. Data transmission stopped on December 11, 1959, after 84days of operation. The data obtained provided a comprehensive surveyof the earth&apos;s magnetic field over the area covered, defined the loweredge of the Van Allen radiation belt, and provided a count ofmicrometeoroid impacts.  Vanguard 3 has an expected orbital lifetimeof 300 yr.                  - Auxiliary Information -    Launch Date and Time :  1959-09-18 05:16:00    Epoch Date and Time  :  1959-09-18 14:24:00    Apogee (km or AU):      3744.

text: The first Chinese Carbon Dioxide Observation Satellite Mission (TanSat) was launched on December 21, 2016. It carries two instruments on-board: the Atmospheric Carbon-dioxide Grating Spectrometer (ACGS) and the multiple-band Cloud and Aerosol Polarization Imager (CAPI). TanSat flies in a sun-synchronous low Earth orbit (LEO) with an equator crossing time around 13:30 local time. The satellite operates in three measurement modes: nadir (ND), glint (GL) and target (TG). The swath width of TanSat measurements is ~18 km across the satellite track and contains 9 footprints each with a size of 2 km × 2 km in nadir. Nadir and glint mode alternate orbit-by-orbit, and the TanSat nadir model ground track is typically between two OCO-2 tracks, which provides potential future opportunities for combined usage of both data products for increased spatial coverage.

text: CFOSAT is a joint mission of the Chinese (CNSA) and French (CNES) space agencies with the goal to monitor the ocean surface winds and waves and to provide information on related ocean and atmospheric science and applications. The primary objective of CFOSAT is to monitor on a global scale the wind and waves at the ocean surface in order to improve:

• The wind and wave forecast for marine meteorology (including severe events)

• The ocean dynamics modeling and prediction

• Our knowledge of climate variability

• Fundamental knowledge on surface processes linked to wind and waves.

An operational demonstration objective of CFOSAT is to provide observations over the ocean in near-real-time for assimilation in meteorological and wave forecast models. Wind and wave products must be available in operational centers within 3 hours after acquisition.

CFOSAT will also be used to complement other satellite missions for the estimation of land surface parameters (in particular soil moisture and soil roughness), and polar ice sheet characteristics.

    <skos:definition xml:lang="en">SNOE (&apos;snowy&apos;) was a small scientific satellite that measured the effects of energy from the sun and from the magnetosphere on the density of nitric oxide in the Earth&apos;s upper atmosphere. The spacecraft and its instruments were designed and built at LASP, the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder. SNOE was launched on February 26, 1998, and was operated from the mission operations center at the LASP Space Technology Research building. SNOE re-entered the Earth&apos;s atmosphere on Dec. 13, 2003, completing a very successful mission. This site contains a description of the SNOE mission, spacecraft drawings and images, and provides access to the scientific data and publications.

text: Due to the success of COSMIC-1, U.S. agencies and Taiwan decided to move forward with a follow-on Global Navigation Satellite System Radio Occultation (GNSS-RO) mission called FORMOSAT-7/COSMIC-2 (COSMIC-2). The six COSMIC-2 satellites launched successfully on June 25, 2019 into low-inclination orbits. U.S. agencies, led by the National Oceanic and Atmospheric Administration (NOAA) and Air Force (USAF) are partnering with Taiwan&apos;s National Space Organization (NSPO), UCAR, and others to execute the COSMIC-2 program. The GNSS-RO payload, named TGRS for Tri-GNSS Radio-occultation System, was developed by NASA&apos;s Jet Propulsion Laboratory and is tracking more than 4,000 high-quality profiles per day (across the 6 satellite constellation). COSMIC-2 also includes two space weather science payloads: a Radio Frequency Beacon (RFB) transmitter and an Ion Velocity Meter (IVM). The COSMIC-2 mission provides a revolutionary increase in the number of atmospheric and ionospheric observations, which will greatly benefit the research and operational communities.

NASA’s Orbiting Carbon Observatory satellite failed to reach orbit after its 4:55 a.m. EST liftoff Feb. 24 (2009) from California’s Vandenberg Air Force Base.

Preliminary indications are that the fairing on the Taurus XL launch vehicle failed to separate. The fairing is a clamshell structure that encapsulates the satellite as it travels through the atmosphere.

The spacecraft did not reach orbit and likely landed in the Pacific Ocean near Antarctica, said John Brunschwyler, the program manager for the Taurus XL.

A Mishap Investigation Board is to determine the cause of the launch failure.

The Orbiting Carbon Observatory (OCO) is a new Earth orbiting mission sponsored by NASA&apos;s Earth System Science Pathfinder Project (ESSP) Program. The ESSP Program funds competitively selected, low to moderate cost Earth Science missions. These highly focused missions acquire exploratory measurements of the atmosphere, the oceans, the land surface and the solid Earth. These missions share a common goal of improving the capability of Earth scientists to predict changes in weather, climate and natural hazards.

After launch in 2009, the OCO mission will collect precise global measurements of carbon dioxide (CO2) in the Earth&apos;s atmosphere. Scientists will analyze OCO data to improve our understanding of the natural processes and human activities that regulate the abundance and distribution of this important greenhouse gas. This improved understanding will enable more reliable forecasts of future changes in the abundance and distribution of CO2 in the atmosphere and the effect that these changes may have on the Earth&apos;s climate.

The Jet Propulsion Laboratory will lead the OCO effort. Orbital Sciences Corporation and Hamilton Sundstrand Sensor Systems will partner with JPL to realize this vital mission.

NASA’s Orbiting Carbon Observatory satellite failed to reach orbit after its 4:55 a.m. EST liftoff Feb. 24 (2009) from California’s Vandenberg Air Force Base.

Preliminary indications are that the fairing on the Taurus XL launch vehicle failed to separate. The fairing is a clamshell structure that encapsulates the satellite as it travels through the atmosphere.

The spacecraft did not reach orbit and likely landed in the Pacific Ocean near Antarctica, said John Brunschwyler, the program manager for the Taurus XL.

A Mishap Investigation Board is to determine the cause of the launch failure.

The Orbiting Carbon Observatory (OCO) is a new Earth orbiting mission sponsored by NASA&apos;s Earth System Science Pathfinder Project (ESSP) Program. The ESSP Program funds competitively selected, low to moderate cost Earth Science missions. These highly focused missions acquire exploratory measurements of the atmosphere, the oceans, the land surface and the solid Earth. These missions share a common goal of improving the capability of Earth scientists to predict changes in weather, climate and natural hazards.

After launch in 2009, the OCO mission will collect precise global measurements of carbon dioxide (CO2) in the Earth&apos;s atmosphere. Scientists will analyze OCO data to improve our understanding of the natural processes and human activities that regulate the abundance and distribution of this important greenhouse gas. This improved understanding will enable more reliable forecasts of future changes in the abundance and distribution of CO2 in the atmosphere and the effect that these changes may have on the Earth&apos;s climate.

The Jet Propulsion Laboratory will lead the OCO effort. Orbital Sciences Corporation and Hamilton Sundstrand Sensor Systems will partner with JPL to realize this vital mission.

text: GOSAT-2 is a follow-on Japanese mission of GOSAT/Ibuki. The experiences gained from the operation of the GOSAT mission with regard to payload calibration and validation activities served as input for the requirements of the GOSAT-2 mission. GOSAT-2 was launched on 29 October 2018.

The goals for the GOSAT-2 are to measure carbon dioxide at 0.5 ppm and methane at 5 ppb at a 500 km mesh. Developers have also enhanced the satellite&apos;s focused, target-point observation capabilities, enabling the device to gather accurate readings from a broader range of target points - an ability that will be especially beneficial in evaluations of industrial areas, densely populated areas, and other areas with large quantities of greenhouse gas emissions. In another improvement over its predecessor, the GOSAT-2 is also capable of monitoring carbon monoxide concentrations.

text: Seirios is one of two of the remotely operated vehicles (ROVs) aboard NOAA Ship Okeanos Explorer. Much like its namesake, Seirios acts as a brilliant source of light in the “night sky” of the ocean, providing illumination and a wide-angle view from above for its counterpart ROV, the Deep Discoverer (D2).

Referred to in the industry as a ‘camera sled,’ Seirios is directly tethered via a cable to the Okeanos Explorer and then is further tethered to D2. This cable provides power to the ROVs as well as a pathway for data transfer between the vehicles and the ship. This configuration allows Seirios to absorb the heave from the ship while keeping D2 stable as it explores the ocean floor and gives ROV pilots from the Global Foundation for Ocean Exploration  on board the Okeanos an expanded view of D2 and surrounding areas. This tandem robot configuration allows stunning imagery to be captured for an undisturbed look at the seafloor, literally shedding light on a location’s features and inhabitants.

Seirios is equipped with a scanning 360-degree sonar as well as a series of cameras, including one high-definition camera and several standard-definition cameras. Three rear-mounted LED light banks aimed forward and below the vehicle illuminate D2 from above. Seirios is also outfitted with a complement of sensors similar to those found on D2 that measure conductivity, temperature, dissolved oxygen, depth, and other information from the ocean and help to better characterize each of the areas that are explored.

While Seirios usually isn’t the star of the show, it plays an invaluable role in allowing the dynamic duo of robots to explore the ocean together.

text: The Synchronous Meteorological Satellite (SMS) system is described which is being utilized in a program to obtain day and night information on the earth&apos;s weather by means of earth imaging, retransmission of imaged data, meteorological data collection and relay, and space environment monitoring. The components and functions of the ground system are discussed together with the basic satellite payloads. The launch and orbit of SMS-A are reviewed, and the functions of the visible IR spin-scan radiometer are described in detail. Other systems and units discussed include the data collection system, solar environment monitor, weather-facsimile unit, and central data distribution system. It is noted that SMS-A was used to support the Global Atlantic Tropical Experiment and that the SMS system will be complemented by geostationary environmental satellites from ESRO, Japan, and the USSR.

    <skos:definition xml:lang="en">ENVISAT was successfully launched on March 1, 2002 from Kourou, FrenchGuiana on Europe&apos;s Ariane 5 launcher.The ENVIronmental SATellite (ENVISAT) is an element of the EuropeanSpace Agency (ESA) Columbus Programme. The ENVISAT satellite is partof the International Earth Observation System (IEOS). The ENVISAT isdesigned to study Earth&apos;s resources and to contribute to the study ofland surface properties, atmospheric chemistry, aerosol distribution,ocean and ice processes, and marine biology. The ENVISAT spacecraftis based on the Polar Platform (PPF) concept and consists of a ServiceModule (SM) which provides main support functions, and amission-specific Payload Module (PLM) which provides the instrumentsand payload support functions. The Payload Module consists of thePayload Equipment Bay (PEB) and the Payload Carrier (PLC). The PayloadData Management Subsystem performs instrument and support subsystems,data processing, telecommand and telemetry management, data-buscontrol, failure management, and instrument operations timelinemanagement. Commonad and control is provided by the Payload ModuleComputer (PMC). Scientific data generated from the instruments will beprocessed by the High Speed Multiplexer (HSM) for recording ortransmission to the ground.  A set of four tape recorders provide arecording speed of 2 to 4 Mbps and a capacity of 25 Gbits. Thecommunication subsystem uses an x-band link directly to the ground anda Ka-band bi-directional link via ESA&apos;s Data Relay Satellite(DRS). The Thermal Control Subsystem consists of a Heater SwitchingUnit (HSU), heaters, thermistors and thermostats. The Service Module(SM) consists of a carbon-fibre-reinforced plastic (CFRP) cone with alauncher interface at one end and a propulsion module at theother. The power subsystem consists of up to eight nickel-cadmiumbatteries (40 Ahr) and a modular solar array. The SM on-board datamanagement is done by the Central Computer Unit (CCU). Command andcontral are done via S-band communications direct to the ground orthrough the DRS. The Attitude and Orbit Control Subsystem (AOCS)provides three-axis stabilization.  Altitude measurements will beprovided by digital Sun sensors, Earth-horizon sensors and gyroscopeswhile altitude control will be provided by monopropellentthrusters. Fine pointing is accomplished through star sensors andgyroscopes, reaction wheels, and magneto-torquers.The ENVISAT consists of : (1) Advanced SAR (ASAR), (2) Global OzoneMonitoring by Occultation of Stars (GOMOS), (3) Medium Resolution ImagingSpectrometer (MERIS), (4) Michelson Interferometer for Passive AtmosphericSounding (MIPAS), (5) Radar Altimeter-2 (RA-2), (6) Advanced Along TrackScanning Radiometer (AATSR), (7) Scanning Imaging Absorption Spectrometerfor Atmospheric Cartography (SCIMACHY), (8) Microwave Radiometer (MWR),(9) Doppler Orbitography and Radiopositioning Integrated by Satellite(DORIS), and (10) a Laser Retroreflector (LRR) for tracking.Just weeks after celebrating its tenth year in orbit, communication with the Envisat satellite was suddenly lost on 8 April. Following rigorous attempts to re-establish contact and the investigation of failure scenarios, the end of the mission is being declared.Group: Platform_Details   Entry_ID: ENVISAT   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: ENVISAT      Long_Name: Environmental Satellite   End_Group   Group: Platform_Associated_Instruments      Short_Name: RA-2      Short_Name: MWR      Short_Name: MIPAS      Short_Name: MERIS      Short_Name: LRR      Short_Name: GOMOS      Short_Name: DORIS      Short_Name: ASAR      Short_Name: AATSR   End_Group   Group: Orbit      Orbit_Altitude: 800-km      Orbit_Inclination: 98.55 degrees      Equator_Crossing: 10 am Local time: e.g.      Repeat_Cycle: 35 days      Orbit_Type: LEO &gt; LOW EARTH ORBIT &gt; POLAR SUN-SYNCHRONOUS   End_Group   Creation_Date: 2007-09-20   Online_Resource: http://envisat.esa.int/   Sample_Image: http://www.dutchspace.nl/uploadedImages/Business_Fields/Earth_observation/Envisat/Envisat-in-Orbit-512.jpg   Group: Platform_Logistics      Launch_Date: 2002-03-01      Launch_Site: KOUROU, FRENCH GUIANA      Design_Life: 10 years      Primary_Sponsor: European Space Agency   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">- Spacecraft Brief Description -The Magsat project was a joint NASA/United States Geological Survey (USGS)effort to measure near-earth magnetic fields on a global basis. Objectivesincluded obtaining an accurate description of the earth&apos;s magnetic field,obtaining data for use in the update and refinement of world and regionalmagnetic charts, compilation of a global crustal magnetic anomaly map, andinterpretation of that map in terms of geologic/geophysical models of theearth&apos;s crust. The spacecraft was launched into a low, near-polar, orbit by theScout vehicle. The basic spacecraft was made up of two distinct parts: theinstrument module that contained a vector and a scalar magnetometer and theirunique supporting gear; and the base module that contained the necessarydata-handling, power, communications, command, and attitude-control subsystemsto support the instrument module. The base module complete with its subsystemswas comprised of residual Small Astronomy Satellite (SAS-C) hardware. Themagnetometers were deployed after launch to a position 6 m behind thespacecraft. At this distance, the influence of magnetic materials from theinstrument and base module (chiefly from the star cameras) was less than 1 nT.                  - Auxiliary Information -    Launch Date and Time :  1979-10-30 14:16:00    Epoch Date and Time  :  1979-10-31    Apogee (km or AU):      578.4    Perigee (km or AU):     351.9    Inclination (degree) :  96.8    Orbit Type :            Geocentric    Information last updated on 1992-04-13Group: Platform_Details   Entry_ID: MAGSAT   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: MAGSAT   End_Group   Group: Synonymous_Platform_Names      Short_Name: AEM-3   End_Group   Group: Orbit      Orbit_Inclination: 96.8 deg      Perigee: 351.9 km      Apogee: 578.4 km   End_Group   Creation_Date: 2007-11-20   Online_Resource: http://www.daviddarling.info/encyclopedia/M/Magsat.html   Sample_Image: http://www.daviddarling.info/images/Magsat.jpg   Group: Platform_Logistics      Launch_Date: 1979-10-30      Launch_Site: Vandenberg Air Force Base, USA      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

text: The EarthCARE satellite will carry four instruments for observations of clouds and aerosols with four synergistic sensing methodologies.

The three-axis stabilised satellite platform was designed to accommodate the four instruments, which need unobstructed and very accurately collocated views of Earth as well as unobstructed views for solar calibration of the passive instruments.

The satellite design meets these challenges by employing a fully customised carbon fibre-based platform with the radar, lidar and startrackers (used for determining the satellite’s attitude) positioned as close together as possible, thereby minimising alignment errors.

The satellite is dominated by the large Cloud Profiling Radar (CPR) antenna, which is 2.5 m across. The long trailing solar panel at the rear gives the satellite an overall length of 19 m. The solar panel is made up of five sections and covers an area of 21 sq m and, at the satellite’s low orbital altitude, helps minimise atmospheric drag.

EarthCARE will orbit Earth at an altitude of around 393 km. The altitude needs to be as low as possible to optimise the use of the lidar and radar, but not too low where atmospheric drag would impact fuel consumption and the life of the mission.

Since global coverage is required, EarthCARE’s orbit is near-polar. It crosses the equator in the early afternoon, providing optimal illumination and minimal sun glint for the passive instruments.

The system’s power demand is significant. The two active instruments, the Atmospheric Lidar (ATLID) and the CPR, require 2500 W.

The size of the satellite (with solar panel and CPR antenna stowed for launch) and its mass of about 2000 kg plus fuel makes it compatible with both Soyuz and Zenit launchers.

    <skos:definition xml:lang="en">The EarthCARE satellite will carry four instruments for observations of clouds and aerosols with four synergistic sensing methodologies.The three-axis stabilised satellite platform was designed to accommodate the four instruments, which need unobstructed and very accurately collocated views of Earth as well as unobstructed views for solar calibration of the passive instruments.The satellite design meets these challenges by employing a fully customised carbon fibre-based platform with the radar, lidar and startrackers (used for determining the satellite’s attitude) positioned as close together as possible, thereby minimising alignment errors.The satellite is dominated by the large Cloud Profiling Radar (CPR) antenna, which is 2.5 m across. The long trailing solar panel at the rear gives the satellite an overall length of 19 m. The solar panel is made up of five sections and covers an area of 21 sq m and, at the satellite’s low orbital altitude, helps minimise atmospheric drag.EarthCARE will orbit Earth at an altitude of around 393 km. The altitude needs to be as low as possible to optimise the use of the lidar and radar, but not too low where atmospheric drag would impact fuel consumption and the life of the mission.Since global coverage is required, EarthCARE’s orbit is near-polar. It crosses the equator in the early afternoon, providing optimal illumination and minimal sun glint for the passive instruments.The system’s power demand is significant. The two active instruments, the Atmospheric Lidar (ATLID) and the CPR, require 2500 W.The size of the satellite (with solar panel and CPR antenna stowed for launch) and its mass of about 2000 kg plus fuel makes it compatible with both Soyuz and Zenit launchers.</skos:definition>

language code: en</skos:changeNote>
    <skos:definition xml:lang="en">GeoEye-1, formerly known as OrbView-5, is the next-generation high-resolution imaging mission of GeoEye, Dulles, VA, USA. In January 2006, the commercial imaging company GeoEye was formed, made up of former Orbimage of Dulles VA, and of former Space Imaging of Thornton, CO (Orbimage acquired Space Imaging in 2005 and gave the merged company the new name of GeoEye). The newly formed GeoEye company is the world&apos;s largest commercial satellite imagery provider.On Sept. 30, 2004, OrbImage was awarded a NextView vendor contract of NGA (National Geospatial-Intelligence Agency). The contract, referred to as NextView OrbImage, provides long-term revenue commitments as well as capital for the development of OrbView-5. NGA&apos;s NextView program is designed to give US commercial imaging satellite operators the financing to build their satellites for high-resolution imaging.GeoEye&apos;s principal partners for the development and launch of the GeoEye-1 satellite include General Dynamics (formerly Spectrum Astro), ITT Industries (imager), and Boeing Launch Services. GeoEye&apos;s partners for the ground segment include IBM and MDA (MacDonald, Dettwiler and Associates) of Richmond, BC, Canada.he GeoEye-1 spacecraft is being designed and developed at General Dynamics/C4 Systems of Gilbert, AZ (formerly Spectrum Astro) as prime contractor. The contract was award in Dec. 2004. The spacecraft design is based on the SA-200HP standard modular bus (of Coriolis and SWIFT heritage). The spacecraft is 3-axis stabilized with a sophisticated attitude control system to provide a highly stable, while also highly agile imaging platform.A body-pointing capability of up to ± 60º is being provided, made possible by enhanced reaction wheels (low jitter). The image geolocation accuracy is ≤ 3 m. The spacecraft mass is 1955 kg (bus mass = 1260 kg), the S/C design is fully redundant with an operational life of 7 years (the expected life is 10 years).Orbit: Sun-synchronous circular orbit, altitude = 684 km, inclination = 98º, period = 98 minutes, local equatorial crossing at 10:30 hours, effective revisit time capability ≤ 3 days.Launch: A launch of GeoEye-1 is scheduled for August 2008 on a Delta-2 (7420-10) vehicle from VAFB, CA. The launch provider is ULA (United Launch Alliance). The launch delay from the fall of 2007 is due to a launch congestion at VAFB.RF communications: The source data are being stored on solid-state onboard recorders of 1.2 Tbit capacity. The downlink of imagery in X-band at 740 Mbit/s (or at 150 Mbit/s), the TT&amp;C data are in S-band. The S/C is being operated from the command and control facility at GeoEye headquarters in Dulles, VA, along with an imagery acquisition station. Three other acquisition stations will be operated or leased by GeoEye in Barrow, AK, Tromsø, Norway and Troll, Antarctica (the TrollSat station is located at 72º S and 2º E). The latter two stations are being leased from KSAT (Kongsberg Satellite Services) of Tromsø, Norway.A total of four stations are needed to handle primary data reception due to the large volume of data that will be captured by the satellite. In addition, GeoEye will continue to support a network of receiving stations owned and operated by local business partners, referred to as Regional Affiliates and Regional Distributors.Ground segment: GeoEye has built a fully integrated receiving, processing, and distribution network for delivering high-quality imagery products to customers around the world.In late 2006, GeoEye purchased high-bandwidth, high-performance compute technology from SGI (Silicon Graphics Inc.). Four SGI Altix systems were installed at the Dulles (VA) ground station for data processing, distribution, and archiving services.Sensor complement: (GIS)The requirements of GeoEye-1 call for panchromatic imagery with a resolution of 0.41 m and multispectral imagery with a resolution of 1.64 m. The imager is being designed and developed by ITT Space Systems Division, formerly Kodak Remote Sensing Systems of Rochester, New York, which built also the sensor for Ikonos-2 (launch April 27, 1999). In January 2007, the GeoEye-1 imager system was delivered to General Dynamics for integration into the spacecraft.GIS (GeoEye Imager System). GIS is a pushbroom imaging system whose basic elements are the optics subsystem (telescope assembly), the focal plane assembly (CCD detector), and the digital electronics subsystem. The optics subsystem employs a TMA (Three Mirror Anastigmatic) telescope design with a primary mirror aperture of 1.1 m in diameter. Three mirrors are used to image and focus the light, and two additional mirrors to direct the image to the FPA (Focal Plane Assembly). The telescope is designed to give a near-perfect (diffraction limited) image to the FPA and to convert the analog pixels into digitized signals.The FPA consists of an array of CCD detectors with 8 µm pixel size for PAN and 32 µm pixel size for multispectral imagery. ITT has included an outer barrel and door assembly to help protect the telescope and maintain its thermal environment.Group: Platform_Details   Entry_ID: GEOEYE-1   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: GEOEYE-1   End_Group   Group: Synonymous_Platform_Names      Short_Name: ORBVIEW-5   End_Group   Group: Platform_Associated_Instruments      Short_Name: CCD IMAGER   End_Group   Group: Orbit      Orbit_Altitude: 684 km      Orbit_Inclination: 98 degrees       Equator_Crossing: 10:30 AM      Period: 98 minutes      Repeat_Cycle: 3 days      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2008-06-27   Online_Resource: http://launch.geoeye.com/LaunchSite/about/fact_sheet.aspx   Online_Resource: http://directory.eoportal.org/get_announce.php?an_id=13708   Sample_Image: http://launch.geoeye.com/LaunchSite/assets/images/about/satellite.gif   Group: Platform_Logistics      Launch_Date: 2008-08-22      Design_Life: 10 YEARS      Primary_Sponsor: US National Geospatial-Intelligence Agency   End_GroupEnd_Group</skos:definition>

Due to the success of CBERS-1 and 2, the two governments decided, in November 2002, to give continuity to the CBERS program by signing a new agreement for the development and launch of two more satellites, CBERS-3 and 4.

Brazilian participation in this program will be enlarged up to 50%, thus taking Brazil to a condition of equality with its partner. CBERS-3 is expected to be launched in 2009, CBERS-4 in 2011.

CBERS-3 and 4 satellites represent an evolution of CBERS-1 and 2. Four cameras will be present in the payload module, with improved geometrical and radiometric performance.

They are: PanMux Camera-PANMUX, Multi-spectral Camera-MUXCAM, Scanning Medium Resolution Scanner-IRSCAM and Wide Field Imaging Camera-WFICAM.

The orbits of the two satellites will be the same as for CBERS-1 and 2.

Four cameras will be present in the payload module, with improved geometrical and radiometric performance.They are: PanMux Camera-PANMUX, Multi-spectral Camera-MUXCAM, Scanning Medium Resolution Scanner-IRSCAM and Wide Field Imaging Camera-WFICAM.The orbits of the two satellites will be the same as for CBERS-1 and 2.

text: In advance of DEEP SEARCH 2019’s first remotely operated vehicle (ROV) dive today, Woods Hole Oceanographic Institution (WHOI) has shared the following overview about ROV Jason. Check back soon for our impressions of the first dive of the cruise. We’ll be diving at Richardson Hills and are expecting to see some spectacular coral habitats!

Jason is an ROV system designed and built by WHOI’s National Deep Submergence Laboratory and funded by the National Science Foundation. Its design gives scientists access to most of the globe’s seafloor, often for days at a time, without leaving the deck of a ship.

The vehicle can operate as either a two-body (with ROV Medea) or a single-body system, depending on mission requirements. A 10-kilometer (6-mile) reinforced fiber-optic cable delivers electrical power and control signals from the ship to the vehicle and returns data and live video imagery throughout a dive. When Medea is used, it acts as a “shock absorber” shielding Jason from the movement of the ship and cable. For the DEEP SEARCH mission, Jason will be operated in single-body mode with a series of floats attached to the cable to dampen the influence of the surface swell.

Jason is equipped with sonars, video and still imaging systems, lighting, and a flexible payload of sensors and sampling systems. The vehicle’s manipulator arms collect samples just by picking them up, or by deploying sampling gear provided by the science team, such as push cores and mussel pots. The samples are then placed in the vehicle’s basket or on “elevator” platforms that float samples to the surface, permitting Jason to stay submerged for as much as a week at a time.

The main objective of the TanDEM-X mission is to generate an accurate three-dimensional image of Earth that is homogeneous in quality and unprecedented in accuracy. At present, the elevation models that are available for large parts of Earth are of low resolution, inconsistent or incomplete. In addition, they are commonly based on different data sources and survey methods. TanDEM-X, TerraSAR-X add-on for Digital Elevation Measurement, is designed to close these gaps and deliver a homogenous elevation model that should prove indispensable for many scientific and commercial applications. Orbiting Earth at an altitude of around 500 kilometres, the two nearly-identical radar satellites have begun mapping its surface.

The first of the two, TerraSAR-X, has been operating since 2007. Three years years on, it has been joined by its twin satellite, TanDEM-X. Flying in close formation only a few hundred metres apart, the two satellites are imaging the terrain below them simultaneously, from different angles. These images are processed into accurate elevation maps with a 12-metre resolution and a vertical accuracy better than 2 metres. The amount of data generated by the satellites will grow to 1.5 petabytes within three years, corresponding to a storage capacity of almost 200,000 DVDs. Like the TerraSAR-X mission, TanDEM-X is a project developed under a public-private partnership between the German Aerospace Center, DLR, and Astrium GmbH based in Friedrichshafen, Germany.

The TanDEM-X mission

The TanDEM-X mission will survey all 150 million square kilometres of Earth&apos;s land surface several times over during its three-year mission. Apart from its high measuring-point density (a 12-metre grid) and high vertical accuracy (better than two metres), the elevation model generated by TanDEM-X will have another unrivalled advantage – being entirely homogenous, it will serve as a basis for maps that are globally consistent. Conventional maps are often fragmented along national borders, or difficult to reconcile as they are based on different survey methods or because of time lags between survey campaigns.

Together TanDEM-X and TerraSAR-X are form the first configurable synthetic aperture radar interferometer in space. Besides this primary goal, the mission has several secondary objectives based on new and innovative methods such as along-track interferometry, polarimetric synthetic aperture radar interferometry, digital beamforming and bistatic radar. The TanDEM-X satellite follows the TerraSAR-X design with minor modifications such as an additional cold gas propulsion system (powered by high-pressure nitrogen gas) to enable fine-tuning of its relative position during formation flying and an additional S-band receiver to receive status and position information sent by TerraSAR-X. The TanDEM-X satellite has been designed for a nominal lifetime of five years and has a planned overlap with TerraSAR-X of three years. TerraSAR-X holds consumables and resources for up to seven years of operation however, potentially allowing for a prolongation of the overlap and the duration of the TanDEM-X mission

text: Pleiades is the optical component of the ORFEO system developed in cooperation with Italy.

The Pleiades system is an optical observation system with a metric resolution designed to offer a high acquisition capability with a revisit lower than 24 hours to satisfy both civilian and military needs.

Moreover, to meet the needs for detailed mapping, especially in urban areas and to complement aerial photography, Pleiades will offer instantaneous stereoscopic acquisition and the capability to cover large areas.

For applications such as forestry, geology and marine environment, and using its spectral characteristics and its tree-dimensional characterization of surfaces, Pleiades should complete the information supplied by other sensors, such as Spot 5, by offering information with a better spatial resolution.

Lastly, to meet the defence and civil security missions, the Pleiades system is expected to:

Supply the information in a very short time-frame (usually less than 24 hours).
Ensure to defence users a priority in the daily programming of the 50 acquisition requests.
Ensure to defence users the confidentiality of their requests and communications.
Enable priority acquisitions on a predefined area with a &quot;crisis&quot; mode implementation.
For this, the Pleiades system is constituted of a constellation of two optical satellites (visible and near infrared domain) on a Sun-synchronous orbit at 694 km. This number of satellites is essential to guarantee the accessibility and revisit frequency required to operationally answer to defence and civil security missions.

With its two agile satellites, the Pleiades system will offer:

a daily access to every point on Earth,
a resolution of 0.7 m in vertical viewing in panchromatic,
four spectral bands (blue, green, red and near infrared) with a resolution of 2.8 m in vertical viewing,
a field of view of 20 km,
an acquisition of a 120 km x 120 km image mosaic in the same orbit,
the acquisition of nearly instantaneous stereoscopic couples (or even triplet) of 20 km by 300 km,
the acquisition of cloud free images covering 2 500 000 km² per year,
a very accurate localization of the images (&lt;1 m with ground control points) enabling an optimal use of the data in the Geographical Information Systems (GIS).
Moreover, the great agility of the satellites will enable to minimize the programming conflicts, particularly during the dual use, and to better meet the users&apos; needs.

The ESA Sentinels will be the first series of noperational satellites to meet the Earth lobservation needs of the European Union ESA Global Monitoring for Environment and Security (GMES) programme. The pair of Sentinel-3 satellites will provide global, frequent and near-realtime ocean, ice and land monitoring. It continues Envisat’s altimetry, the multispectral, medium-resolution visible and  infrared ocean and land-surface observations of ERS, Envisat and Spot, and includes enhancements to meet the operational revisit requirements and to facilitate new products and evolution of services. The first launch is expected in 2011/2012.

DEFINITION
The Sentinel-3 (S3) mission of ESA and the EC is one of the elements of the GMES (Global Monitoring for Environment and Security) program, which responds to the requirements for operational and near-real-time monitoring of ocean, land and ice surfaces over a period of 20 years. The topography element of this mission will serve primarily the marine operational users but will also allow the monitoring of sea ice and land ice, as well as inland water surfaces, using novel observation techniques.The Sentinel-3 mission is designed as a constellation of two identical polar orbiting satellites, separated by 180º, for the provision of long-term operational marine and land monitoring services. The operational character of this mission implies a high level of availability of the data products and fast delivery time, which have been important design drivers for the mission.

    <skos:definition xml:lang="en">TiungSat-1 is Malaysia&apos;s first national microsatellite. It was designed and developed in a collaborative effort between the Malaysian government, under the government appointed company ATSB \[Astronautic Technology (Malaysia) Sdn. Bdh.\] of Kuala Lumpur, and SSTL (Surrey Satellite Technology Ltd.) of Surrey, UK. In the view of the Malaysian government, the satellite development program was seen as an impetus for expanding Malaysia&apos;s capability in the area of high-technology industry. The first satellite was named &apos;Tiung&apos; after a beautiful small singing bird in Malaysia. Astronautic Technology Sdn. Bhd. (ATSB) is a research and development organization, which was formed in 1995 by the government of Malaysia. The TiungSat-1 specific applications are in the following fields:* Collection of imagery for environmental and meteorological use* Digital S&amp;F (Store &amp; Forward) communications* Technology demonstration* Space science* Amateur radio accessSpacecraft:The TiungSat-1 S/C structure comprises eleven module trays used to house the electronics for the bus and payload systems. The box-like spacecraft has a size of 690 mm x 360 mm x 360 mm; it is three-axis stabilized using a gravity-gradient boom (6 m boom with tip mass), two 3-axis magnetorquers, and a momentum wheel. Attitude is sensed by two 3-axis magnetometers and by two-axis analog sun sensors. In addition, there are UED (Underneath Earth Detector) and SOD (Sun Overhead Detector). The pointing knowledge is in roll and pitch and in yaw (3 sigma values). The S/C power is 35 W per panel, provided by four surface-mounted GaAs solar panels and by a 10-cell NiCd battery (7 Ah). The power subsystem provides regulated voltage supplies at +5V and 10V along with an unregulated supply which fluctuates between 12-14 V. Autonomous functions, safe modes and data are handled by two OBCs (On-Board Computer), OBC-186 and OBC-386. Onboard data handling via a CAN (Controller Area Network) between platform and payloads. The onboard data storage capacity is 1 Gbit. The S/C mass is 50 kg (platform = 35 kg, payload = 15 kg). The nominal design life is three years.RF communications: TiungSat uses conventional AMSAT frequencies (Malaysian Oscar-46), thereby giving amateur radio operators access to its data (imagery and communication capabilities). The microsatellite features an AX.25 protocol store-and-forward PACSAT protocol suite communications system. The uplink is in VHF-band with a data rate of 9.6 kbit/s; three receivers are used: Rx1 operates at 144.46 MHz, Rx2 and Rx3 operate at 145.86 145.925 MHz, selectable. The downlink is dual-redundant in UHF-band (435 to 438 MHz range with 437.300, 437.325, 437.350, 437.375 MHz, selectable) with data rates of 9.6, and 38.4 kbit/s (experimentally at 76.8 kit/s). An error-protected digital packet communications protocol is used. All spacecraft operations are performed at ATSB in Kuala Lumpur.TiungSat-1 was launched Sept. 26, 2000 on a Dnepr-1 vehicle along with other satellites (the other payloads were: SaudiSat-1A/-1B of SISR (Saudi Institute for Space Research), UniSat of the University of Rome, and MegSat-1 of the MegSat Space Division of &apos;Gruppo Meggiorin,&apos; Bresia, Italy) from the Baikonur Cosmodrome, Kazakhstan.Orbit: Circular orbit, altitude = 650 km, inclination = 64, period = 97 minutes.Spacecraft operations are carried out at ATSB&apos;s Mission Control Station located at the Universiti Kebangsaan Malaysia, Bangi, Selangor. The satellite has also been used in a number of educational activities ranging from the physical sciences to the humanities.Operational status of TiungSat-1 as of 2004: The payload was fully operational well beyond its design life of three years. However, since Jan. 2004, the payload is only being operated intermittently to reduce the power consumption of the battery.Sensor/experiment complement (MSEIS, MEIS, S&amp;F, CEDEX):MSEIS (Multi-Spectral Earth Imaging System). MSEIS is a NAC (Narrow Angle Camera), a multispectral system of three cameras (green, red and near-infrared) in parallel, each with a 75 mm focal length optic and 100 mm aperture diameter. The NAC system provides a 78 m ground spatial resolution in three spectral bands: 510-590 nm, 610-690 nm and 810-890 nm (green, red, and near infrared). A two-dimensional CCD staring array detector with 1024 x 1024 pixels is used providing snapshot imagery of scene size 78 km x 78 km. Up to four contiguous images can be collected along the flight path. The data are digitized to 8 bits radiometric resolution (256 levels).MEIS (Metrological Earth Imaging System). MEIS is a single-band WAC (Wide Angle Camera) system with 6.5 mm focal length optics. It provides NIR imagery (810-890 nm) with a 900 m spatial resolution. The CCD area array detector has a size of 1024 x 1024 elements (pixels) for snapshot observations. Data are quantized to 8 bits radiometric resolution. An image has the size of 900 km x 900 km. The data is being used for meteorological applications.S&amp;F (Digital Store &amp; Forward Communications). The subsystem provides global, frequency-agile, communications for any form of digitized data: e-mail, voice-mail, scientific data exchange, fax, imagery, or even Internet mail for remote regions. The low cost and direct access offered by the TiungSat-1 microsatellite in orbit also makes it ideal for use by scientists, engineers and students based in institutes, universities and even schools throughout the world. - DSPE (Digital Signal Processing Experiment). The DSPE consists of a TM320C31 low power DSP suitable for special or general purpose signal processing tasks on LEO satellites. The VHF scanner operates in the 140-150 MHz range. A built-in FSK decoder is used. The system is capable to detect signals from a pre-set signal strength threshold within selected bar. DSP can be used for processing audio transmission for rebroadcast.CEDEX (Cosmic Ray Energy Deposition Experiment). The objective of CEDEX is to characterize the TiungSat-1 orbit radiation environment in terms of the observed particle LET (Linear Energy Transfer) spectrum at the spacecraft. The primary sensor consists of a 30mm x 30mm PIN diode detector 300 microns in depth, housed in a separate screened aluminium unit mounted on the CEDEX module box (three area PIN-diode detectors are mounted in a &apos;telescopic&apos; arrangement; hence, information pertaining to directions of the energy particles detected can be derived.). This is connected to a charge amplifier and a pulse-shaping circuit which, in turn, are connected to an event-driven, hardware-logic controlled pulse-height multi-channel analyzer. CEDEX is controlled autonomously by a CAN-microcontroller with its own data-storage RAM and built-in data-compression software. This sends data to an internal CAN-controller which formats and sends them on to the primary OBC via the spacecraft&apos;s CAN (Controlled Area Network) bus. CEDEX is a multichannel analyzer with 512 channels and a 0.5 pC (picocoulomb) charge resolution. The instrument charge range is between 0.2 -24 pC, equivalent to a normal incidence particle LET range of about 60 - 7500 MeV cm2 g-1 (200,000 particles/s).The CEDEX data obtained are comparable directly with such instruments as CREDO-II flown on STRV-1c (launch Nov. 16, 2000) and CRE (Cosmic Ray Experiment) flown on KitSat-1 (launch Aug. 10, 1992) and PoSat-1 (launch Sept. 26, 1993).Experimental Microsatellite GPS, an SSTL/ESA collaboration. An advanced 12-channel GPS receiver with two GPS patch antennas is installed for several objectives: 1) onboard generation of Keplerian orbital elements (NORAD experiment, this was first performed on PoSat), 2) onboard navigation, attitude, and timing services, and 3) refractive sounding of the ionosphere. The instrument is primarily used for orbit and position determination and for precise onboard timing services. In parallel, the instrument is also employed for refractive ionospheric monitoring. The TEC (Total Electron Content) occultation observations of the instrument provide slant range measurements which can be converted into vertical profiles.

To do this three CCD cameras observe sections of the sky of size 60 by 3 degree.As the SMEI instrument observers the whole sky, data generated has been used to observe periodic changes in the brightness of stars. This data be used to detect asteroseismological oscillation in giant stars, and for the detection of large eclipsing extra-solar planets.Group: Platform_Details   Entry_ID: Coriolis   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: Coriolis   End_Group   Group: Platform_Associated_Instruments      Short_Name: WINDSAT   End_Group   Group: Orbit      Orbit_Inclination: 98.7      Period: 101.6      Perigee:  842      Apogee:  822      Orbit_Type: LEO &gt; LOW EARTH ORBIT &gt; POLAR SUN-SYNCHRONOUS   End_Group   Creation_Date: 2013-01-09   Group: Platform_Logistics      Launch_Date: 2003-01-06      Launch_Site: VANDENBERG AIR FORCE BASE, USA      Primary_Sponsor: Naval Research Laboratory      Primary_Sponsor: Air Force Research Laboratory   End_GroupEnd_Group</skos:definition>

text: Little Hercules is a 4000m depth rated Remotely Operated Vehicle (ROV), with an impressive past and most promising future. “Little Herc”, as he is widely referred to is just that; “little”. But as we all know, many good things come in small packages. Little Herc came to the Okeanos Explorer through collaboration between NOAA’s Office of Ocean Exploration and Research and Dr. Robert Ballard’s Institute for Exploration (IFE) at the University of Rhode Island (URI). With a major commitment to explore the waters off Indonesia, our Program’s much larger ROV could not be readied in time for our 2010 sailing date. As a result, Little Herc was chosen as our stand-in.

Originally developed by a team of engineers at IFE, Little Herc first came into the spotlight when he gave the world the first and only images of John Kennedy’s PT Boat; PT-109. After several other successful missions for IFE, Little Herc stepped down, taking a back seat to the now much larger and spectacular, “Hercules”. After doing a short stint as an exhibit piece in the Mystic Aquarium, a proposal by the NOAA Office of Ocean Exploration has given new life to the veteran “Explorer”. Through a Joint Project Agreement (JPA) between NOAA, IFE and URI, a team of engineers from several institutions and companies once again went to work, this time recommissioning Little Herc. In a field where technology advances rapidly, it was necessary and appropriate that Little Herc receive a substantial upgrade before joining the ship. After an extensive 4 month overhaul, Little Herc boasted a new motor controller and power bottle system, an upgraded fiber optic multiplexer system, a new Ultra Short Baseline Tracking System (USBL), a full color imaging sonar, a new Conductivity-Temperature-Depth (CTD) sensor, two new single chip color CCD cameras, two new LED lights, two 400watt HMI Lights and a spectacular High Definition video camera. New tethers, new tether terminations, a new transformer, a new electrical junction box, new depth and altitude sensors, a new light bar and a new version of control software to make it all work was in order.

Tested at the University of New Hampshire’s Center for Coastal and Ocean Mapping prior to arrival in Hawaii for field trails, Little Herc has now come full circle. Today, the beautiful images you are seeing are once again, Little Herc’s major contribution. Made possible by the generous support of our partners and engineers, Little Herc is back. Diving deeper, shining brighter and taking higher resolution imagery than ever before! And my thanks to everyone.

It was piloted from a shipboard station, receiving power and commands from the surface control console via a steel armored electro-mechanical fiber optical cable. The vehicle could operate to depths of 914 meters (3000 ft). It was equipped with two color video cameras with lights and a CTD which sent data directly up the wire. RCV-150 was primarily used as a video survey tool that could acquire extremely close-up views because of its small size and maneuverability.

text: Referred to as a “tow sled,” remotely operated vehicle (ROV) Argus typically operates in tandem with ROV Hercules, although it can also operate alone. Both vehicles are deployed from the Ocean Exploration Trust ’s Exploration Vessel (E/V) Nautilus .

Argus “dangles” at the end of a steel-armored fiber-optic cable that is tethered to E/V Nautilus at the sea surface. Because Argus lacks a buoyancy module and is built of heavy stainless steel, its movements are controlled by moving the ship or raising and lowering the cable. A short 100-foot (30-meter) tether connects Hercules to Argus. By keeping the tether between Argus and Hercules slack, Argus can absorb the brunt of any ship movements, so that Hercules, the workhorse of the duo, can remain stable and collect high-definition video from the seafloor.

Argus carries a high-definition video camera similar to the one on Hercules, as well as large lights that illuminate the area around Hercules. The overhead view from Argus allows the pilots and scientists to get a better of view Hercules&apos; surroundings. Thrusters on Argus control its heading, so pilots “flying” the ROV while sitting in the control room on E/V Nautilus can aim the video cameras and lights toward Hercules and sites of interest.

Although Hercules is depth rated to 2.5 miles (4,000 meters), when operating alone, Argus can dive deeper – down to 3.7 miles (6,000 meters).

    <skos:definition xml:lang="en">The Dash (Density And Scale Height) satellites were2.5-m-diameter balloons used to measure air densities ataltitudes of approximately 3500 km. The area-to-mass ratio forthe spacecraft was 40 sq cm/g. The orbit, originally circular,increased in eccentricity rapidly under the action of solarradiation pressure. This experiment used the variations in orbitcharacteristics of the Dash balloon satellite to deduce neutralair densities and to study the effect of solar radiationpressure. Other effects, such as terrestrial radiation pressure,lunar gravity, and solar gravity were also observable.Dash 2 reentered the earth&apos;s atmosphere on April 12, 1971.Additional information available at&apos;http://www.skyrocket.de/space/doc_sdat/dash-1.htm&apos;Group: Platform_Details   Entry_ID: DASH-2   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: DASH-2   End_Group   Group: Synonymous_Platform_Names      Short_Name: DASH-2   End_Group   Creation_Date: 2007-11-19   Online_Resource: http://www.skyrocket.de/space/doc_sdat/dash-1.htm   Group: Platform_Logistics      Launch_Date: 1963-07-19      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

text: GeoEye’s OrbView-3 satellite was among the world’s first commercial satellites to provide high-resolution imagery from space. OrbView-3 collected one meter panchromatic (black and white) or four meter multispectral (color) imagery at a swath width of 8 km for both sensors. One meter imagery enables more accurate viewing and mapping of houses, automobiles and aircraft, and makes it possible to create precise digital products. Four meter multispectral imagery provides color and near infrared (NIR) information to further characterize cities, rural areas and undeveloped land from space.  Imagery from the OrbView-3 satellite complements existing geographic information system (GIS) data for commercial, environmental and national security customers. OrbView-3 orbits 470 km above the Earth in a sun-synchronous polar orbit while collecting imagery of the Earth&apos;s surface at one meter resolution in the Panchromatic (black and white) mode, or at four meter resolution in the Multispectral (color) mode with a three day repeat cycle.

The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center received 179,981 OrbView-3 image “segments” from GeoEye with no restrictions. The data were delivered in Basic Enhanced (Level 1B) radiometrically corrected format. The product files include satellite telemetry data, rational functions, post-processed Ground Sample Distance (GPS) at nadir data, and sufficient metadata for rigorous triangulation.

The data in this collection were acquired between September 2003 and March 2007, from the multispectral (MS) and panchromatic (Pan) sensors.  Over 84% of the Orbview-3 collection is PAN (black &amp; white).

    <skos:definition xml:lang="en">Tsinghua-1 is a microsatellite of Tsinghua University, developed and built in a joint venture between SSTL of Guildford, Surrey, UK, and Tsinghua University in Beijing, China. The TSRC (Tsinghua Space Research Center) was set up in Oct. 1998 with the goal to integrate all space research activities at Tsinghua University and to provide a means and facilities for S/C building. The joint-venture company in Beijing is referred to as T-SSSC (Tsinghua-Surrey Small Satellite Company). The cooperative program is to develop and build microsatellites (Tsinghua-1) and nanosatellites (THNS-1) and to provide integrated training in small satellite design.Tsinghua-1 (also referred to as &apos;Hangtian&apos; in Chinese) is a demonstrator microsatellite in the 50 kg class of size: 35 cm x 35 cm x 64 cm. The overall objective is to provide daily high-resolution imaging for disaster monitoring and mitigation on a worldwide scale. A further goal of Tsinghua-1 is to conduct communications research in LEO. The design uses the new MicroSat-70 platform modules or trays to carry the subsystems and payload. The power subsystem design includes the regulation, protection and distribution of a 35 W solar array and 7 Ah NiCd batteries. This subsystem essentially offers two buses: an unregulated 14 V bus and a regulated 5 V bus. The three payload modules include the GPS receiver (SGR-10 with 12 channels), transputer, and DSP/DTE (Digital Signal Processing/Data Transfer Experiment) unit. The three cameras and 3 reaction wheels are accommodated in the Earth Observation Compartment. Two GPS antennas are accommodated on the space facing side of the S/C.The spacecraft is three-axis stabilized using a combination of passive (gravity-gradient boom) and active (magnetorquers, reaction wheels) actuator elements. The platform is nadir pointing. Attitude is sensed by sun sensors and a magnetometer. The body-pointing platform has the capability to perform fast slew maneuvers within 15 about the roll axis (or 180 about the yaw axis). An off-nadir pointing configuration can be sustained for up to half an orbit. Onboard data handling is provided with a dual CAN (Controller Area Network) bus (ISO 11898 &amp; ISO 11519-1) 20 Mbit/s, and INMOS serial point-to-point link 9.6 kbit/s asynchronous duplex UART (Universal Asynchronous Receiver/Transmitter).A launch of Tsinghua-1, along with SNAP-1 of SSTL as secondary payloads to Nadezhda-6, the prime Russian S&amp;RSAT (Search &amp; Rescue Satellite) of COSPAS, took place on June 28, 2000 on a Russian Cosmos-3M launcher from the Plesetsk Cosmodrome, Russia.Orbit: Sun-synchronous circular orbit, altitude = 700 km, inclination = 98, period of 100 minutes.Status of Tsinghua-1 mission: The spacecraft is operational as of 2004. Sensor complement:MEIS (Multispectral Earth Imaging System).MEIS is a demonstrator instrument intended for the upcoming DMC (Disaster Monitoring Constellation) mission. The objective is to acquire multispectral Earth surface imagery with a spatial resolution of 40 m (snapshot imagery). The MEIS camera assembly consists of three cameras (one for each spectral band) mounted at an angle of 15 from nadir so that the yaw angle can be selected to offer the required off-pointing angle of 15 from nadir. The image swath width is 80 km and each camera can collect four images contiguously along the flight path. The instrument performs autonomous onboard histogram analysis to ensure optimum image quality involving image processing, compression and onboard storage. The OBCs may also be used to carry out autonomous onboard cloud editing and high-compression thumb-nail image previews.SGR-10 (Space GPS Receiver-10). The objective is real-time positioning for tracking the satellite and providing orbital elements for the spacecraft mission and ground station. SGR is a customized COTS-developed receiver. The instrument is based on the second generation GPS chip set of MITEL Semiconductors. The SGR consists of the following elements: GPS antennas, LNAs, the RF section, the digital section and the TLM/TC node. RF section: The SGR has two separate RF front-ends in the RF section which are responsible for down-converting the GPS signals and digitizing the IF signals. The RF sections use the same local oscillator so that the measurements are referenced to the same fundamental TCXO clock.Digital section: This part consists of hardware correlator channels, memory, a 32 bit RISC microprocessor with supporting peripherals and the interface circuitry. There are 24 C/A code correlation channels available, although only 12 channels are available if only 2 antennas are used.TLM/TC node: A separate 8 bit microcontroller is used to provide telemetry and telecommands. The telemetry includes status monitoring of SGR, while telecommand include reset, power down parts of the receiver, some redundancy switching etc.The SGR-10 receives the L1 signal from the GPS constellation. The total SGR mass is 1.355 kg, including antenna/LNA. The accuracy of positioning, velocity and time synchronization (under Selective Availability on GPS) are: 150 m, 1 m/s, 3-D, 2 sigma approximately, and + 1 s, respectively.

QuikSCAT was initiated as a &quot;quick recovery&quot; mission to help reduce the ocean-wind vector data gap created by the loss of the NASA Scatterometer (NSCAT) on the Japanese Advanced Earth Observing Satellite (ADEOS), which ceased functioning when ADEOS failed on June 30, 1997. QuikSCAT was launched from Vandenberg Air Force Base, Calif., aboard a Titan II vehicle, reducing the data gap by about one-half.

QuikSCAT operates in a near polar orbit. It flies in a circular orbit at an altitude of approximately 800 km (500 miles) above Earth&apos;s surface. It completes a full orbit in about 101 minutes, which translates to a little more than 14 orbits per day.

SeaWinds is the main instrument on the QuikSCAT satellite. SeaWinds is an active radar scatterometer. This scatterometer operates by transmitting high-frequency microwave pulses to the ocean surface and measuring the echoed radar pulses bounced back to the satellite. The scatterometer estimates wind speed and direction over the Earth&apos;s oceans at 10 m above the surface of the water. The instrument collects data over ocean, land, and ice in a continuous, 1,800-kilometer-wide band, making approximately 400,000 measurements and covering 90% of Earth&apos;s surface in one day. QuikSCAT can acquire hundreds of times more observations of surface wind velocity each day than can ships and buoys, and can provide continuous, accurate and high-resolution measurements of both wind speeds and direction regardless of weather conditions. This data is vital for global climate research, operational weather forecasting, and storm warning.

The SeaWinds scatterometer is providing unprecedented, frequent surface wind speed and direction measurements over the global oceans. Coupled with other satellite measurements of cloud patterns, water vapor and rain, the data are contributing to scientists&apos; ability to predict the intensity, location and movements of hurricanes and other severe marine weather patterns.

QuikSCAT operates in a near polar orbit. It flies in a circular orbit at an altitude of approximately 800 km (500 miles) above Earth&apos;s surface. It completes a full orbit in about 101 minutes, which translates to a little more than 14 orbits per day.

SeaWinds is the main instrument on the QuikSCAT satellite. SeaWinds is an active radar scatterometer. This scatterometer operates by transmitting high-frequency microwave pulses to the ocean surface and measuring the echoed radar pulses bounced back to the satellite. The scatterometer estimates wind speed and direction over the Earth&apos;s oceans at 10 m above the surface of the water. The instrument collects data over ocean, land, and ice in a continuous, 1,800-kilometer-wide band, making approximately 400,000 measurements and covering 90% of Earth&apos;s surface in one day. QuikSCAT can acquire hundreds of times more observations of surface wind velocity each day than can ships and buoys, and can provide continuous, accurate and high-resolution measurements of both wind speeds and direction regardless of weather conditions. This data is vital for global climate research, operational weather forecasting, and storm warning.

The SeaWinds scatterometer is providing unprecedented, frequent surface wind speed and direction measurements over the global oceans. Coupled with other satellite measurements of cloud patterns, water vapor and rain, the data are contributing to scientists&apos; ability to predict the intensity, location and movements of hurricanes and other severe marine weather patterns.

Telemetry indicated the fairing, the protective shell atop the Taurus XL rocket, did not separate as expected about three minutes after launch. //[Source: Glory Science Home Page, http://glory.giss.nasa.gov/ ]Glory is a remote-sensing Earth-orbiting observatory designed to achieve two separate mission objectives. One is to collect data on the chemical, microphysical, and optical properties, and spatial and temporal distributions of aerosols. The other is to continue collection of total solar irradiance data for the long-term climate record.The Glory mission&apos;s scientific objectives are met by implementing two separate science instruments, one with the ability to collect polarimetric measurements along the satellite ground track within the solar reflective spectral region (0.4 to 2.4 micrometers) and one with the ability to monitor changes in sunlight incident on the Earth&apos;s atmosphere by collecting high accuracy, high precision measurements of total solar irradiance. Glory accomplishes these objectives by deploying two instruments aboard a low earth orbit satellite, the Aerosol Polarimetry Sensor (APS) and the Total Irradiance Monitor (TIM). Additionally, a cloud camera system will provide images that allow the APS scans along the spacecraft ground track to be put into spatial context and to facilitate determination of cloud occurrence within the APS instantaneous field of view.Group: Platform_Details   Entry_ID: GLORY   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: GLORY   End_Group   Group: Platform_Associated_Instruments      Short_Name: TIM      Short_Name: CC GLORY      Short_Name: APS GLORY   End_Group   Group: Orbit      Orbit_Altitude: 705 km +/- 30 km      Orbit_Inclination: 98.2 Degrees +/- 0.15 Degrees      Equator_Crossing: 1:35 p.m.      Period: 99 Minutes      Repeat_Cycle: 16 Days      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-11-09   Online_Resource: http://glory.giss.nasa.gov/   Online_Resource: http://glory.gsfc.nasa.gov/   Sample_Image: http://glory.gsfc.nasa.gov/images/gloryinorbit-s.jpg   Group: Platform_Logistics      Launch_Date: 2011-03-04      Launch_Site: VANDENBERG AIR FORCE BASE, USA      Design_Life: + 3 years; 5 year goal      Primary_Sponsor: USA/NASA   End_GroupEnd_Group</skos:definition>

text: HotSat-1, launched in June 2023, (and operational until December 2023) is a cutting-edge satellite developed by British company Satellite Vu (SatVu).

The satellite is the first of its kind to offer commercially available high-resolution thermal infrared imaging of Earth. It is designed to track heat variations from industries, infrastructure and other assets, providing valuable insights into energy efficiency, environmental monitoring, and the impacts of climate change

The satellite&apos;s primary mission is to collect the highest resolution thermal data from space for a safer and more sustainable Earth. The images captured by SatVu’s first satellite, HotSat-1, show heat variations across the surface of the earth at a resolution of up to 3.5 m, both during the day and at night. Thermal data at this unparalleled resolution has wide applications, from economic monitoring and national security to climate resilience including urban heat monitoring.

HotSat-1 is the first in a planned constellation of nine satellites which SatVu has envisaged for consistent monitoring of thermal emissions on Earth.

After suffering a technical anomaly in December 2023, the satellite ceased operating. However, the second and third satellites of the constellation are planned for launch in the upcoming year.

Until ceasing operation, HotSat-1 was able to image the same location every 1-2 days while orbiting the Earth at an altitude of 500 km. The satellite communicated with a global network of ground stations to receive tasking requests and deliver data, with a downlink speed of 450 Mbps.

Applicants will be given access to SatVu’s self-service platform which allows users to browse their existing data catalogue. The data can be downloaded on a scene-by-scene basis, with each scene covering an area of 16 km2 (3.5km x 4.5km). The files are delivered as cloud-optimised GeoTIFFs of, on average, 10 MB and are accompanied by metadata following the STAC specification.

HotSat-1 Mission Parameters:
Orbit Type:	Sun synchronous
Orbit Altitude:	        500 km
Ascending Node:	00:39
Spacecraft Weight:	130 kg
Swath (Standard Scene Size):	4.5 km (across-track) x 3.5 km (along-track)
Orbit Off-Nadir Angle (ONA):	0-45°
Ground Sampling Distance (GSD):	3.5 m (nadir) to 6.8 m (45° ONA)
Spectral Band:	Night: 3.7-5 μm Day: 4.5-5 μm
Revisit Frequency (40° latitude):	1 day (45° max. ONA) to 2 days (30° max ONA)
Sensor Sensitivity:	&lt; 2 K
Capacity:	200 scenes per day
Dynamic Range:	16 bit
Georeferencing Accuracy:	30 m CE90 without ground control

Objectives:
The primary objectives of HotSat-1 are to provide high-resolution thermal infrared imaging of the Earth. The satellite aims to monitor heat variations from industry and infrastructure to support activity monitoring, security intelligence, and climate impact analysis.

The satellite&apos;s frequent revisits to the same location allowed for near daily data collection, aiding in applications such as industrial activity monitoring and energy management. The data is intended to help identify areas of energy loss, monitor industrial activity, and support various sectors in managing environmental and energy-related challenges.

Instruments:
HotSat-1 uses a MWIR (Mid Wave InfraRed) imaging sensor that captures heat emissions from the Earth&apos;s surface. The instrument was designed and supplied by the Italian company Leonardo and has an array of pixels on an 8 μm pitch – the smallest thermal MWIR pixels commercially available at the time of development.

Each scene is captured with a ground sampling distance (GSD) of between 3.5 metres and 6.8 metres depending on the imaging angle. Specifically, the sensor measures the intensity of this radiation to determine temperature differences as small as 2°C or better.

Two modes are possible which allow for both daytime and nighttime image capture. At night, the sensor is sensitive to radiation in the range 3.7-5 μm; during daylight hours, a filter is applied to reduce noise from reflected solar radiation, giving a range of 4.5-5 μm for daytime imaging.

    <skos:definition xml:lang="en">CHAMP will generate for the first time simultaneously highly precise gravityand magnetic field measurements over a 5 years period. This will allow us todetect besides the spatial variations of both fields also their variabilitywith time. The CHAMP mission will open a new era in geopotential research andwill become a significant contributor to the Decade of Geopotentials. It willperform the following three tasks: 1) Mapping of the Earth&apos;s global long tomedium wavelength gravity field and temporal variations with applications inthe geophysics, geodesy and oceanography; 2) Mapping of the Earth&apos;s globalmagnetic field and temporal variations with applications in geophysics andsolar terrestrial physics; 3) Atmosphere/ionosphere sounding with applicationsin global climate studies, weather forecasting, disaster research andnavigation.CHAMP-derived data will serve as an ideal basis for a further refinement ofmodern satellite surveying methods and constructing digital terrain modelscovering large land and ice areas for remote sensing applications and forcartography. The evaluation of all three kinds of signals CHAMP will beobserving will allow a complete and integrated modeling of the structure anddynamics of the Earth core and mantle. Such an improvement will stronglyenhance studies concerning the structure and composition of the Earth&apos;sinterior and will open new insights and application areas in geodesy, solidEarth physics and oceanography.Launch: Launched: July 15, 2000Launch Site: Plesetzk, RussiaOrbit:  Altitude: 450 km and circularInclination: 87.27Period: 94 minutesNon-Sun-SynchronousVital Statistics:  Weight: 500 kgPower: 167 wattsDesign Life: 5 yearsInstruments: LRR (Laser Retro Reflector)OVM (Overhauser Magnetometer) and the FGM (Fluxgate Magnetometer)DIDM (Digital Ion Drift Meter)ACC (Accelerometer)GPS (Global Positioning System) ReceiverCHAMP home Page:  http://op.gfz-potsdam.de/champ/[Summary provided by NASA.]Group: Platform_Details   Entry_ID: CHAMP   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: CHAMP      Long_Name: Challenging Minisatellite Payload   End_Group   Group: Synonymous_Platform_Names      Short_Name: CHAMP   End_Group   Group: Platform_Associated_Instruments      Short_Name: CHAMP-BLACKJACK      Short_Name: MAGNETOMETERS      Short_Name: FLUXGATE MAGNETOMETERS      Short_Name: DIDM      Short_Name: ACCELEROMETERS      Short_Name: GPS   End_Group   Group: Orbit      Orbit_Altitude: 450 km      Orbit_Inclination: 87.27      Period: 94 min      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Non-Sun-Synchronous   End_Group   Creation_Date: 2007-09-24   Online_Resource: http://op.gfz-potsdam.de/champ/   Online_Resource: http://science.nasa.gov/missions/champ/   Online_Resource: http://eospso.gsfc.nasa.gov/eos_homepage/mission_profiles/show_mission.php?id=66   Sample_Image: http://www.gfz-potsdam.de/pb1/op/champ/media_CHAMP/champ_startconf.jpg   Group: Platform_Logistics      Launch_Date: 2000-07-15      Launch_Site: Plesetsk Cosmodrome, Russia      Primary_Sponsor: Germany/GFZ      Primary_Sponsor: USA/NASA   End_GroupEnd_Group</skos:definition>

text: SENTINEL-5 is a European Earth observation mission developed to support the European Commission Copernicus Programme for monitoring the earth.

 

The SENTINEL-5 mission consists in a single instrument which is a UV-VIS-NIR-SWIR spectrometer observing the earth in nadir mode with a wide swath. It is embarked as a Customer Furnished Item (CFI) on the MetOp-SG A satellite (illustrated in Figure 1) which is operated by EUMETSAT as part of the EPS-SG (EUMETSAT Polar System Second Generation) system.

 

The main objective of the SENTINEL-5 mission is to perform atmospheric measurements, with high spatio-temporal resolution, relating to air quality, climate forcing, ozone and UV radiation and providing a daily global coverage.

text: Owned and operated by the Ocean Exploration Trust , Hercules is a remotely operated vehicle (ROV) equipped with special features that allow it to perform intricate tasks while descending to depths of 2.5 miles (4,000 meters). Hercules operates off Exploration Vessel (E/V) Nautilus  and always with its tandem vehicle, Argus.

Hercules carries an array of lighting, cameras, and acoustic sensors that are used to gather video and other data during each dive. Hercules’ four HMI lights and high-definition video camera allow scientists to closely examine a dive site and monitor operations. Video is streamed up a fiber-optic cable to a control van on Nautilus and then out to the world on the Internet .

Two manipulator arms allow Hercules to collect biological and geological samples and to recover artifacts. Other sensors measure pressure, depth, water temperature, oxygen concentration, and salinity.

As a remotely operated vehicle, Hercules is controlled (remotely) by pilots located in a mission control room aboard E/V Nautilus, who use the vehicle’s six thrusters to &quot;fly&quot; the ROV in any direction.

text: OCO is a NASA sponsored minisatellite mission selected in July 2002 within the ESSP (Earth System Science Pathfinder) program. The OCO science objective is to provide global measurements of atmospheric carbon dioxide (CO2) needed to describe the geographic distribution and variability of carbon dioxide sources and sinks. CO2 measurements are essential to resolving significant discrepancies in our understanding of the global carbon budget and, hence, humankind&apos;s role in global climate change.

The Orbiting Carbon Observatory, a mission that partners with industry and academia, will generate knowledge needed to improve projections of future carbon dioxide levels within Earth&apos;s atmosphere. Increasing carbon dioxide (CO2) concentrations have raised concerns about global warming. Even though the biosphere and oceans are currently absorbing about half of the CO2 generated by human activities, the nature and geographic distribution of these CO2 sinks are too poorly understood to predict their response to future climate and land-use changes. The OCO mission is led and managed by JPL (PI: David Crisp). The project includes more than 19 universities as well as corporate and international partners (investigators from the USA, France, Germany, New Zealand, and Australia).

text: FireBIRD is an earth observation mission with the primary goal of monitoring fires from space. It involves the detection and measurement of so-called high-temperature events and the provision of remote sensing science data for research at DLR and for external partners.

It is organized as a research and development project under the auspices of DLR’s Aerospace Research and Technology program division with solely science goals, and all aspects of the mission are under DLR control.

The space segment consists of the two satellites TET-1 (Technology Experiment Carrier) and BIROS (Berlin InfraRed Optical System). The TET-1 satellite has been circling Earth in a polar orbit since July 2012 and has successfully concluded the first part of its mission as a technology testing platform. The BIROS satellite has the same bus as TET-1, but is additionally equipped with a propulsion system for active attitude and orbit control. BIROS was launched on 22 June 2016 at 05:55 CEST. The main payload for both satellites is a multispectral camera system.

text: The Haiyang-2 (HY-2) satellite series is a second generation ocean observation satellite, managed by the China National Space Administration (CNSA) and the Chinese Academy of Space Technology (CAST). It is the follow-on mission to the first generation, HY-1A and HY-1B. HY-2’s primary objective was to measure ocean dynamic and regional environmental trends in the microwave spectral range. Further, parameters such as marine wind vector, marine surface heat and Sea Surface Temperature (SST) aid aero-marine forecasts for the prevention of, and relief in the event of, natural disasters. The first Haiyang satellite, HY-2A, was launched in August 2011, producing observational data until its service was terminated in December 2021. The satellite series consists of eight satellites with four currently in operation and four more planned to be launched by 2025.

New Value=Europe&apos;s first ice mission is an advanced radar altimeter specifically designed to monitor the most dynamic sections of Earth&apos;s cryosphere. It borrows synthetic aperture radar and interferometry techniques from standard imaging radar missions to sharpen its accuracy over rugged ice sheet margins and sea ice in polar waters. CryoSat-2 measures &apos;freeboard&apos; - the difference in height between sea ice and adjacent water - as well as ice sheet altitude, tracking changes in ice thickness.</skos:changeNote>

text: ASIM is a climate observatory designed for detecting transient luminous event and terrestrial gamma ray flashes. ASIM will be mounted externally on the European Space Laboratory on ISS, Columbus. The ASIM payload consists of four sub-systems, CEPA, DHPU, MXGS, and MMIA. The CEPA and DHPU form the structural and electrical platform servicing the MXGS and MMIA scientific instruments. The DHPU, MXGS, and MMIA are mounted on-top of the CEPA. The power and data connections from ISS are routed through the CEPA to the DHPU, which converts 120V ISS supply to 28V instrument supply and handles all data communication.

Old Value=The Ionospheric Connection Explorer will study the frontier of space: the dynamic zone high in our atmosphere where terrestrial weather from below meets space weather above. In this region, the tenuous gases are anything but quiet, as a mix of neutral and charged particles travel through in giant winds. These winds can change on a wide variety of time scales -- due to Earth&apos;s seasons, the day&apos;s heating and cooling, and incoming bursts of radiation from the sun.

This region of space and its changes have practical repercussions, given our ever-increasing reliance on technology -- this is the area through which radio communications and GPS signals travel. Variations there can result in distortions or even complete disruption of signals. In order to understand this complicated region of near-Earth space, called the ionosphere, NASA has developed the ICON mission. To understand what drives variability in the ionosphere requires a careful look at a complicated system that is driven by both terrestrial and space weather.

ICON will help determine the physics of our space environment and pave the way for mitigating its effects on our technology, communications systems and society.

This experiment isdesigned to increase knowledge about gravity-gradient tetherdynamics and the survivability of tethers in space. (Tethers canbe severed by space debris.) The National Reconnaissance Office(NRO) is a sponsor of the TiPS program. While tethers have beentheoretically studied as a means for satellite stabilization,propulsion, and electricity generation for some time, TiPS isamong the first successful tether deployments in space and isthe first experiment designed for long duration.Additional information available athttp://projects.nrl.navy.mil/tips/[Summary provided by U.S. Military]Group: Platform_Details   Entry_ID: TIPS   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: TIPS      Long_Name: Tether Physics and Survivability   End_Group   Group: Synonymous_Platform_Names      Short_Name: TIPS   End_Group   Group: Platform_Associated_Instruments      Short_Name: RIS   End_Group   Group: Orbit      Orbit_Altitude: 1,022 km      Orbit_Inclination: 63.4 deg      Period: 105 min      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Inclined Non-Polar   End_Group   Creation_Date: 2007-11-28   Online_Resource: http://projects.nrl.navy.mil/tips/   Sample_Image: http://code8100.nrl.navy.mil/programs/images/tips2_corner_lg.jpg   Group: Platform_Logistics      Launch_Date: 1996-06-20      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The Solar Mesosphere Explorer (SME) mission objective was primarily toinvestigate the processes that create and destroy ozone in the Earth&apos;smesosphere and upper stratosphere. Some specific goals were (1) todetermine the nature and magnitude of changes in mesospheric ozonedensities resulting from changes in the solar ultraviolet flux; (2) todetermine the interrelationship between solar flux, ozone, and thetemperature of the upper stratosphere and mesosphere; (3) to determinethe interrelationship between ozone and water vapor; and (4) todetermine the interrelationship between nitrogen dioxide andozone. The satellite experiment complement consisted of a solarultraviolet spectrometer, an ultraviolet ozone spectrometer, aninfrared radiometer, a 1.27-micrometer spectrometer, and a nitrogendioxide spectrometer. In addition, a solar proton alarm detector wascarried on board to measure the integrated solar flux in the range 30to 500 MeV. Spin stabilized at 5 rpm, the satellite moved in a 3a.m. to 3 p.m. sun-synchronous orbit. The spacecraft body was acylinder approximately 1.7 by 1.25 m and consisted of two majormodules: the observatory module that housed the scientificinstruments, and the spacecraft bus. The spin axis was oriented normalto the orbital plane. The command system was capable of executingcommands in real time or from stored program control. Power wassupplied by a solar cell array. The telemetry system was used eitherin a real-time or in a tape-recorder mode. Further details and somemeasurement results are written in C. A. Barth et al., &apos;Solarmesosphere explorer: scientific objectives and results,&apos;Geophys. Res. Lett., v. 10, no. 4, p. 237, 1983. All instruments onboard the SME were turned off in December 1988 because of energyconsiderations.                  - Auxiliary Information -    Launch Date and Time :  1981-10-06 11:27:00    Epoch Date and Time  :  1981-10-16    Apogee (km or AU):      551.

    <skos:definition xml:lang="en">Following the deployment of the Goddard Space Flight Center&apos;s (GSFC) Upper Atmosphere Research Satellite (UARS) on Sept. 15, 1991, from the Space Shuttle Discovery, scientists have gained a better understanding of the energy input, chemistry and dynamics of the upper atmosphere and the coupling between the upper and lower atmosphere. UARS, the first satellite dedicated to studying stratospheric science, focuses on the processes that lead to ozone depletion, complementing and amplifying the measurements of total ozone made by the Total Ozone Mapping Spectrometer (TOMS) onboard NASA&apos;s Nimbus-7 and the Russian Meteor-3 satellites. UARS also measures winds and temperatures in the stratosphere as well as the energy input from the Sun.  Ten UARS instruments have provided the most complete data on upper atmospheric energy inputs, winds, and chemical composition ever gathered. Together, these observations constitute a highly integrated investigation of the nature of the upper atmosphere, and help define the role of the upper atmosphere in climate and climate variability. In its first two weeks of operation, UARS data confirmed the polar ozone-depletion theories by providing three-dimensional maps of ozone and chlorine monoxide near the South Pole during development of the 1991 ozone hole. UARS, developed and managed by GSFC, in Greenbelt, Md., provides information that nations around the world can use to guide decisions on environmental policies, according to scientists.  Moreover, UARS collected data on the chemistry, dynamics, and radiative inputs to the upper atmosphere far beyond its designed lifetime, obtaining over 13 years of observations for many atmospheric constituents, temperature, winds, and external forcings.  UARS was decommissioned in 2005. The United Kingdom and Canada both provided instruments for this mission. UARS is the first spacecraft launched as part of NASA&apos;s systematic, comprehensive study of the Earth system.Instruments: ISAMS (Improved Stratospheric and Mesospheric Sounder)MLS (Microwave Limb Sounder)HALOE (Halogen Occultation Experiment)HRDI (High Resolution Doppler Imager)WIND II (Wind Imaging Interferometer)SOLSTICE (Solar-stellar Irradiance Comparison Experiment)SUSIM (Solar Ultraviolet Spectral Irradiance Monitor)PEM (Particle Environment Monitor)ACRIM II (Active Cavity Radiometer Irradiance Monitor)CLAES (Cryogenic Limb Array Etalon Spectrometer)[Summary provided by NASA]Group: Platform_Details   Entry_ID: UARS   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: UARS      Long_Name: Upper Atmosphere Research Satellite   End_Group   Group: Platform_Associated_Instruments      Short_Name: CLAES      Short_Name: ISAMS      Short_Name: MLS      Short_Name: HALOE      Short_Name: HRDI      Short_Name: WINDII      Short_Name: SOLSTICE      Short_Name: SUSIM      Short_Name: PEM      Short_Name: ACRIM II   End_Group   Group: Orbit      Orbit_Altitude: 585 km circular      Orbit_Inclination: 57 deg      Period: 96.7 min      Perigee: 574 km (356 mi)      Apogee: 582 km (361 mi)      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Non-Sun-Synchronous   End_Group   Creation_Date: 2007-05-09   Online_Resource: http://umpgal.gsfc.nasa.gov/   Online_Resource: http://www.nasa.gov/mission_pages/uars/index.html   Sample_Image: http://umpgal.gsfc.nasa.gov/uars-science/images/uars.jpg   Group: Platform_Logistics      Launch_Date: 1991-09-12      Launch_Site: Cape Canaveral/Kennedy Space Center, USA      Design_Life: 3 years      Primary_Sponsor: NASA - Goddard Space Flight Center   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">GFZ-1 (GeoForschungsZentrum-1) is a geodetic satellite designed to improve thecurrent knowledge of the Earth&apos;s gravity field. The satellite, a passive systemwith no onboard sensors or electronics, is covered with retroreflectors thatreflect laser beams sent from ground stations. By measuring the round trip timeof the transmitted light, the distance between the satellite and the stationcan be determined with approximately 1 centimeter. These measurements are usedto determine variations in the rotational characteristics of the Earth and formeasurement of the Earth&apos;s gravitational field. As the vehicle&apos;s orbit decays,the satellite&apos;s orbital motion will also be used calculate to atmosphericdensities. Deployed from the Mir space station, GFZ-1 was the first non-Russiansatellite launched from MIR. GFZ-1 was developed in under 12 months and costapproximately &amp;#36700,000 (including design, fabrication, test, and launch).Data collection, distribution and evaluation is coor dinated by the project&apos;sscientists at the GeoForschungsZentrum Potsdam.Spacecraft The satellite consists of a spherical body made from brass with 60corner cube reflectors distributed regularly over the satellite&apos;s surface.These retroreflectors are quartz prisms placed in special holders that arerecessed in the satellite&apos;s body.

    <skos:definition xml:lang="en">- Spacecraft Brief Description -This satellite was a part of Japan&apos;s contribution to the InternationalMagnetospheric Study. The mission objectives were to observe the auroraborealis, study aurora-related phenomena, and study the ionosphere andmagnetosphere. The main body of the spacecraft was a cylinder 0.946 m indiameter with shallow truncated cones attached at both ends. Most of thesurface was covered with solar cells that produced 35 W. Two booms of roughly1.9 m each extended outward from the equator of the main body. At the tip ofeach boom was a permanent magnet to provide alignment of the spacecraft centeraxis along the local geomagnetic field line. Two sets of circularly polarizedquadrupole antennas, one for UHF (400 MHz) and another for VHF, extended fromopposite ends of the spacecraft. The VHF antenna was diplexed for telemetry(136 MHz) and command (148 MHz). Other attitude sensors included a vectormagnetometer and a solar sensor. The spacecraft contained a tape recorder tostore 160 min of data at 512 bps or 40 min at 2048 bps, with readout in 10 minat 8192 bps. Besides the solar cells, there was a nickel-cadmium battery fornighttime operation.                  - Auxiliary Information -    Launch Date and Time :  1978-02-04 07:00:00    Epoch Date and Time  :  1978-02-06    Apogee (km or AU):      3978.

text: A planned series of space applications missions whose purpose is to perform various tasks that require a low cost, quick reaction, small spacecraft in a dedicated orbit. The Heat Capacity Mapping Mission (HCMM) is the first mission of this series. The spacecraft described in this document was conceived to support a variety of applications instruments and the HCMM instrument in particular. The maximum use of commonality has been achieved. That is, all of the subsystems employed are taken directly or modified from other programs such as IUE, IMP, RAE, and Nimbus. The result is a small versatile spacecraft. The purpose of this document, the AEM Mission Planners Handbook (AEM/MPH) is to describe the spacecraft and its capabilities in general and the HCMM in particular. This document will also serve as a guide for potential users as to the capabilities of the AEM spacecraft and its achievable orbits. It should enable each potential user to determine the suitability of the AEM concept to his mission.

text: Megha-Tropiques (or MT) is a cooperative experimental mission of ISRO and CNES, the space agencies of India and France, with the objective to study the convective systems (water cycle and energetic exchanges) that affect the ITCZ (Intertropical Convergence Zone), in particular in the latitudes between 10º and 20º, with satisfactory temporal sampling. The most energetic tropical systems, such as the cloud clusters of the ITCZ, the monsoon systems and the tropical cyclones, extend over hundreds of kilometers. Hence, a ground resolution of about 10 km is adequate for these observations. Megha-Tropiques, with its unique combination of scientific payloads and its special near-equatorial orbit (offering improved data sampling of the ITCZ), is expected to provide valuable data for climate research.

    <skos:definition xml:lang="en">The primary objective of the STS-72 mission is to capture and return to Earth a Japanese microgravity research spacecraft known as Space Flyer Unit (SFU). The 7,885lbs SFU spacecraft was launched by Japan&apos;s National Space Development Agency (NASDA) from Tanegashima Space Center in Japan at 8:01 UT on March 18, 1995 aboard a Japanese H-II rocket (HII-3).The STS-72 mission will also deploy (for about 50 hours) and then retrieve the Office of Aeronautics and Space Technology Flyer (OAST-Flyer) spacecraft. OAST-Flyer is the seventh in a series of missions aboard reuseable free-flying Spartan carriers. It consists of four experiments: Return Flux Experiment (REFLEX), Global Positioning System Attitude Determination and Control Experiment (GADACS), Solar Exposure to Laser Ordnance Device (SELODE) and the University of Maryland Spartan Packet Radio Experiment (SPRE).Other experiments onboard STS-72 include the Shuttle Solar Backscatter Ultraviolet Experiment (SSBUV-8) (previously flown on STS-34, STS-41, STS-43, STS-45, STS-56, STS-62 and STS-66), EDFT-03, Shuttle Laser Altimeter Payload (SLA-01/GAS(5)), VDA-2, National Institutes of Health NIH-R3 Experiment, Space Tissue Loss Experiment (STL/NIH-C), Pool Boiling Experiment (PBE) (hardware previously flown on STS-47, STS-57 and STS-60) and the Thermal Energy Storage (TES-2) experiment (previously flown on STS-69).Get Away Special payloads include the United States Air Force Academy G-342 Flexible Beam Experiment (FLEXBEAM-2), Society of Japanese Aerospace Companies&apos; G-459 - Protein Crystal Growth Experiment and the Jet Propulsion Laboratory GAS Ballast Can with Sample Return Experiment.Endeavour&apos;s 10th flight also includes two 6.5 hour spacewalks by three astronauts to test hardware and tools that will be used in the assembly of the International Space Station starting in late 1997. EVA-1 on flight day five consists of Crewmembers Leroy Chiao (EV1) and Dan Barry (EV2) while EVA-2 on Flight Day 7 consists of Leroy Chiao (EV1) and Winston Scott (EV2).[Summary provided by NASA]Group: Platform_Details   Entry_ID: STS-72   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: STS-72      Long_Name: Space Transport System STS-72   End_Group   Group: Synonymous_Platform_Names      Short_Name: Endeavour   End_Group   Group: Orbit      Orbit_Altitude: 250 nm (288 statute miles)      Orbit_Inclination: 28.45 degrees   End_Group   Creation_Date: 2008-01-30   Online_Resource: http://science.ksc.nasa.gov/shuttle/missions/sts-72/mission-sts-72.html   Sample_Image: http://www.nasa.gov/images/content/134518main_sts-72-crew-sm.jpg   Group: Platform_Logistics      Launch_Date: 1996-01-11      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

Old Value=Grumman developed the Gulfstream I turbine powered executive transport to replace the many hundred war surplus piston twins performing such missions in the mid 1950s.

Design work began in 1956, with first flight of the Gulfstream I prototype occurring on August 14 1958. FAA Type certification was awarded on May 21 1959 and deliveries of production aircraft followed from that June. Notably, the Gulfstream I was the first US twin engined corporate transport to be certificated to cruise at 30,000ft.

    <skos:definition xml:lang="en">The Atmospheric Explorer-D (AE-D) spacecraft (designation: 08353 /75096A ) was designed as a multi- sided polyhedron shaped frame with amean diameter of about 1.4 meters.  AE-D was in most respects similarto AE-C. The AE-D was launched on 1975-10-6 and decayed 1976-03-12.The purpose of the AE-D mission was a direct continuation of the EA-Cmission: to investigate the chemical and physical processes in theuppermost layer of the earth&apos;s atmosphere, the thermosphere, withemphasis on energy transfer and other controlling processes.Photochemical processes related to the absorption of solar UVradiation were studied by making coordinated measurements of reactingconstituents and the solar input in the region of high absorption ofsolar energy.The payload included instrumentation to measure: Solar UV Fluxes, theComposition of Positive Ions and Neutral Particles, the Density andTemperature of neutral particles, positive ions and electrons,Atmospheric airglow emissions, Photoelectron Energy Spectra, andProton and Electron Fluxes with particle energy up to 25 keV.This mission was planned to sample the high latitude regions at thesame time that the AE-E mission was sampling the equatorial and lowlatitude regions.  The same type of spacecraft as AE-C was used, andthe payload consisted of the same types of instruments except fordeletion of the extreme solar UV monitor and the Bennett ion massspectrometer both of which were part of the AE-E payload.AE-D was placed in a high inclination (polar) orbit.  The polar orbitprovided sampling of all latitudes, the perigee moved through alllatitudes in 3 months, and all local times in 4 months.Unfortunately, a failure in the solar power panels resulted in thetermination of AE-D operations on January 29, 1976, after slightlyless than 4 months of useful spacecraft life.  However, all theregions at the perigee altitudes were sampled during this time.  TheAE-D spacecraft re-entered the earth&apos;s atmosphere about 1 month afterthe cessation of telemetry.  To continue the correlated observationswith the AE-E mission, the earlier AE-C spacecraft was thenreactivated on February 28, 1976 as replacecment for AE-D. Power toAE-D was supplied by a solar cell array.  The spacecraft used a PCMtelemetry data system that operated in real time or using a taperecorder.Group: Platform_Details   Entry_ID: AE-D   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: AE (Atmosphere Explorer)      Short_Name: AE-D      Long_Name: Atmosphere Explorer D (Explorer 54)   End_Group   Group: Synonymous_Platform_Names      Short_Name: Explorer 54      Short_Name: 08353   End_Group   Group: Platform_Associated_Instruments      Short_Name: MASS SPECTROMETERS   End_Group   Creation_Date: 2007-08-22   Online_Resource: http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1975-096A   Group: Platform_Logistics      Launch_Date: 1975-10-06       Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The fifth Orbiting Geophysical Observatory, OGO-5, was launched on 4 March1968. The satellite, primarily devoted to Earth observation, was in a highlyelliptical initial orbit with a 272 km perigee and an 148,228 km apogee. Theorbital inclination was 31.1 degrees. The satellite took 3796 minutes tocomplete one orbit. Two experiments aboard OGO-5 produced cosmic high- energyresults, although their intended target was the Sun. The spacecraft attitudecontrol failed on 6 August 1971 and it was placed in a standby mode on 8October 1971. Three experiments (none of which were related to cosmichigh-energy detection) were reactivated from 1 June to 13 July 1972. Operationof OGO 5 terminated completely on 14 July 1972.The Anderson et al. (University of California, Berkeley) Energetic Radiationsfrom Solar Flares experiment was operational from March 1968 - June 1971.Primarily devoted to solar observations, it detected at least 11 cosmic X-raybursts in time coincidence with gamma-ray bursts seen by other instruments. Thedetector was a 0.5 cm thick NaI(Tl) crystal with a 9.5 sq-cm area. Data wereaccumulated into energy ranges of: 9.6-19.2, 19.2-32, 32-48, 48-64, 64-80,80-104, 104-128, and &gt; 128 keV. The data were sampled for 1. 15 seconds onceevery 2.3 seconds.The gamma-ray instrument on-board, sensitive to energies from 25-100 MeV, was asix gap spark chamber with an effective area of ~ 100 sq-cm. It was called theEnergetic Photons in Primary Cosmic Rays experiment (Hutchinson et al.,Southampton University). It had an angular resolution of ~ 30 degrees (FWHM).The satellite was Earth-pointing and passed regularly through the radiationbelts, which led to severe restrictions on the sky regions which could beexamined by the gamma-ray instrument.

    <skos:definition xml:lang="en">The SMS satellite series (1 and 2) were spin-stabilized (100 rpm) andoperated in a West-to-East, geo-synchronous orbit at an altitude of35,800 km (22,300 mi) above the equator.  These were the first andsecond prototypes for the GOES satellite series.  At this altitude itcircled the axis of the Earth once in 24 hours, making its speedsynonymous with the Earth&apos;s rotation, so that the satellite remainedessentially stationary over a given geographical point. The two SMSsatellites were employed to provide overlapping coverage that centerson the U.S. and extends over the eastern Atlantic Ocean and thewestern Pacific Ocean.  The scanning system consisted of a mirror thatis stepped mechanically to provide North to South viewing, while therotation of the satellite provided West to East scanning.  The mirroris stepped following each West to East scan, with each step resultingin a change in scan angle of 192 microradians, or 7 km near nadir.  Asequence of 1821 scans is performed to provide a &apos;full disk&apos; view fromthe Northern to the Southern Earth horizon.  At the rotation rate of100 rpm, 18.21 minutes are required to complete one full North toSouth view of the Earth.  The VISSR field of view provides a groundresolution of 0.9km in the visible, and 3.0km in the infrared.Entry taken from:Cornillon, P., A Guide to Environmental Satellite Data, University of RhodeIsland Marine Technical Report 79, 1982.Data Catalog Series for Space Science and Applications Flight Missions,National Space Science Data Center/World Data Center A for Rockets andSatellites, Volume 2A, September 1982.Data Catalog Series for Space Science and Applications Flight Missions,National Space Science Data Center/World Data Center A for Rockets andSatellites, Volume 4A, July 1985.Rao, P.K., S.J.

The cone-shaped spacecraft was 3.05 m in  diameter  at the largest end, which was the rear of the craft. The major   objectives   of   this   mission  were  to  demonstrate  (1) a long-duration  manned  flight  using  a  fuel  cell  power system, (2) rendezvous  capabilities,  and  (3)  rendezvous  maneuvers. scientific studies  included  zodiacal  light, synoptic terrain, synoptic weather photography, and a cloud top spectrometer experiment. In addition, five medical  and seven technological experiments were performed during the mission.  The  120-orbit  flight  lasted 8 days, returning to earth on august 29, 1965.

text: As of 2010, Clelia has been retired from active deployment and placed on display at the Georgia Aquarium as the centerpiece of their deep sea research methods exhibit.

Owned and operated by Harbor Branch Oceanographic Institution, Clelia is a PC 1204 submersible built by Perry Oceanographics in 1976 and refitted in 1992 by Harbor Branch to address the needs of the shallow water scientific community. At 23 ft long, 8 ft 3 in wide and 9 ft 7 in high, the Clelia travels at a maximum speed of 3 knots and is classed and certified to a maximum operating depth of 1,000 feet by the American Bureau of Shipping (ABS).

The vehicle can accommodate two scientists/observers and a pilot allowing excellent visibility through the forward acrylic hemisphere. The proximity of the occupants to the bottom (approximately 18&quot;) allows tasks to be completed in areas of low visibility. Researchers are afforded an excellent view of the ocean environment through 10 view ports. A hemispheric, 3-ft-diameter window is located at the front end of the sub. Eight 8-in diameter ports are equally spaced around the conning tower of the sub, and one upward view port is in the center of the overhead hatch.

Clelia is outfitted with active sonar, still and video cameras, as well as a seven-function hydraulic manipulator equipped with a suction sampler, clam bucket scoop and jaws capable of handling bottom cores and other sampling devices. The manipulator can lift up to 150 lbs. The various collections are placed in the rotating sampler that allows for both quantitative and qualitative sampling. The Clelia is equipped with still and video cameras. Two 500-watt metal halide lights, ideal for photography, can illuminate an area to near-daylight conditions.

The highly maneuverable submersible is ideally suited for multiple short dives as well as longer duration, more complex dives. The Clelia can be balanced midwater to absolutely neutral buoyancy, providing an extremely stable platform from which to observe, collect samples and shoot photographs and video.

Typical applications include benthic and/or mid-water observations, photo/video documentation and collection of organisms; dump site inspections and monitoring; punch and box coring; search and recovery; bottom surveys; photogrammetric surveys; archaeological site documentation and recovery; and environmental impact studies.

Maintained and operated by experienced and expert pilots and crew, it is further supported by an in-house engineering staff. Working with the support staff, researchers also can add their own equipment, usually other cameras or sampling equipment, to the Clelia. The additional equipment, however, must be tested and certified that it can withstand deep-sea pressures. Harbor Branch also requires that researchers provide their equipment ahead of time to ensure that it can be interfaced properly with the Clelia’s existing equipment.

Old Value=Identical to Pioneer 6, Pioneer 7 was put into heliocentric orbit at 0.814 x 0.985 AU to study the solar magnetic field, the solar wind, and cosmic rays at widely separated points in solar orbit. 

On 7 September 1968, the spacecraft was correctly aligned with the Sun and Earth to begin studying Earth&apos;s magnetic tail. 

In 1977, eleven years after its launch, Pioneer 7 registered the magnetic tail 19.3 million kilometers out, three times further into space than recorded previously. 

On 20 March 1986, the spacecraft flew within 12.3 million kilometers of Halley&apos;s Comet and monitored the interaction between the cometary hydrogen tail and the solar wind. 

As with Pioneer 6 and Pioneer 8, NASA continues to maintain intermittent contact with Pioneer 7, more than thirty years after its mission began. On 31 March 1995, for example, the plasma analyzer was turned on during 2 hours of contact with the ground.

    <skos:definition xml:lang="en">[Source: NOAA-N Project home page, http://www.nasa.gov/mission_pages/noaa-n/main/index.html ]NOAA-N is the latest polar-orbiting satellite developed by NASA for the National Oceanic and Atmospheric Administration (NOAA). NOAA-N will collect information about Earth&apos;s atmosphere and environment to improve weather prediction and climate research across the globe.NOAA-N is the 15th in a series of polar-orbiting satellites dating back to 1978. NOAA uses two satellites, a morning and afternoon satellite, to ensure every part of the Earth is observed at least twice every 12 hours.Severe weather is monitored and reported to the National Weather Service which broadcasts the findings to the global community. With the early warning, effects of catastrophic weather events can be minimized.  NOAA-N also has instruments to support an international search-and-rescue program. The Search and Rescue Satellite-Aided Tracking System, called COPAS-SARSAT, transmits to ground stations the location of emergency beacons from ships, aircraft and people in distress around the world. The program, in place since 1982, has saved about 18,000 lives.NOAA-N is the first in a series of polar-orbiting satellites to be part of a joint cooperation project with the European Organisation for the Exploitation of Meteorological Satellites (EUMESTAT).

text: The Apollo program was the name of NASA&apos;s project to land humans on the moon in the 1960s and early 1970s. With the success of Apollo 11 in 1969, which put astronauts on the lunar surface for the first time in history, the U.S. was able to declare victory in the space race against the Soviet Union during the Cold War. 

Beginning in 1961, the Apollo program consisted of 11 total spaceflights; four of those tested equipment, and six of the other seven flights landed people on the moon, according to NASA. The first crewed flight occurred in 1968, and the final mission occurred in 1972. 

By the time the Apollo missions came to an end, 12 astronauts had walked on or driven over the moon&apos;s surface, conducting scientific research and snagging rocks to bring back to researchers on Earth. These samples are still being used to make new discoveries more than 50 years after they were collected.

Old Value=The Johnson-Sea-Link I and II were retired by Harbor Branch Oceanographic Institution in 2011 after their support ship the R/V Seward Johnson was sold to Cepemar Environmental Services of Brazil.

The Johnson-Sea-Link (JSL) I and II are owned and operated by Harbor Branch Oceanographic Institution. At 23.6 ft long, 10.9 ft high and 8.3 ft wide, these highly maneuverable submersibles can dive to a depth of 3,000 ft and travel at a maximum speed of one knot. Edwin Albert Link, engineer, inventor, and friend of Harbor Branch founder Seward Johnson, working at Harbor Branch, designed and built the JSL in 1971, at Mr. Johnson’s request. Harbor Branch constructed the JSL II, which is virtually identical to the JSL I, in 1975.

The JSL has two separate pressure hulls and can accommodate four people. Aft compartment occupants enter the sub through a bottom-facing 20 inch-wide hatch. The front chamber, which contains the sub’s controls, is a 5-ft-diameter sphere made of five-in thick, clear acrylic. It provides a panoramic view for the pilot and one observer. Because acrylic is a good insulator and hampers conductivity of cold ocean temperatures, the front compartment actually requires air conditioning. The second chamber, the stern compartment, houses another crewmember and a second observer. The occupants have access to two side view ports and a video monitor.

Download larger version (jpg, 476 KB).

The human-occupied vehicle (HOV) Alvin enables direct data collection and observation by two scientists of the seafloor and water column to depths reaching 2.8 miles (4,500 meters) on dives lasting up to 10 hours with the support of an experienced, multi-talented support team. The Alvin Group  and their equipment meet the highest safety and reliability standards as a result of decades of operational and engineering expertise. Continual innovation and the application of the latest technological advancements puts Alvin at the forefront of expeditionary research.

Its seven reversible thrusters permit Alvin to hover in the water, maneuver over rugged topography, or rest on the seafloor. With an experienced pilot at the controls, it can collect data throughout the water column, produce a variety of maps, and perform photographic surveys. Alvin also has two robotic arms that can manipulate instruments and obtain samples  ranging from hard-rock geology to delicate biology, and its sampling basket can be reconfigured daily based on the needs of each dive.

Alvin is a proven and reliable platform capable of diving for up to 30 days in a row before requiring a scheduled maintenance day. Recent collaborations with autonomous vehicles such as Sentry have proven expansive, allowing research teams to visit promising sites to collect samples and data in-person within hours of being discovered, and University-National Oceanographic Laboratory System (UNOLS)-driven technological advances have improved the ability for scientific outreach and collaboration via telepresence.

Currently rated to 4,500 meters, Alvin gives researchers in-person access to about two-thirds of the ocean floor. The sub’s most recent upgrade, completed in 2014, increased the depth rating of many of the vehicle’s systems, putting it just steps away from having a depth rating of 4.04 miles (6,500 meters) that would provide access to approximately 98 percent of the seafloor.

text: The Pioneer programs were two series of United States lunar and planetary space probes exploration. The first program, which ran from 1958 to 1960, unsuccessfully attempted to send spacecraft to orbit the Moon, successfully sent one spacecraft to fly by the Moon, and successfully sent one spacecraft to investigate interplanetary space between the orbits of Earth and Venus. The second program, which ran from 1965 to 1992, sent four spacecraft to measure interplanetary space weather, two to explore Jupiter and Saturn, and two to explore Venus. The two outer planet probes, Pioneer 10 and Pioneer 11, became the first of five artificial objects to achieve the escape velocity that will allow them to leave the Solar System.

text: The Johnson-Sea-Link I and II were retired by Harbor Branch Oceanographic Institution in 2011 after their support ship the R/V Seward Johnson was sold to Cepemar Environmental Services of Brazil.

The Johnson-Sea-Link (JSL) I and II are owned and operated by Harbor Branch Oceanographic Institution. At 23.6 ft long, 10.9 ft high and 8.3 ft wide, these highly maneuverable submersibles can dive to a depth of 3,000 ft and travel at a maximum speed of one knot. Edwin Albert Link, engineer, inventor, and friend of Harbor Branch founder Seward Johnson, working at Harbor Branch, designed and built the JSL in 1971, at Mr. Johnson’s request. Harbor Branch constructed the JSL II, which is virtually identical to the JSL I, in 1975.

The JSL has two separate pressure hulls and can accommodate four people. Aft compartment occupants enter the sub through a bottom-facing 20 inch-wide hatch. The front chamber, which contains the sub’s controls, is a 5-ft-diameter sphere made of five-in thick, clear acrylic. It provides a panoramic view for the pilot and one observer. Because acrylic is a good insulator and hampers conductivity of cold ocean temperatures, the front compartment actually requires air conditioning. The second chamber, the stern compartment, houses another crew member and a second observer. The occupants have access to two side view ports and a video monitor.

text: The Sentinel-3 (S3) mission of ESA and the EC is one of the elements of the GMES (Global Monitoring for Environment and Security) program, which responds to the requirements for operational and near-real-time monitoring of ocean, land and ice surfaces over a period of 20 years. The topography element of this mission will serve primarily the marine operational users but will also allow the monitoring of sea ice and land ice, as well as inland water surfaces, using novel observation techniques.The Sentinel-3 mission is designed as a constellation of two identical polar orbiting satellites, separated by 180º, for the provision of long-term operational marine and land monitoring services. The operational character of this mission implies a high level of availability of the data products and fast delivery time, which have been important design drivers for the mission.

Old Value=Landsat 5 is the fifth satellite of the Landsat program. It was launched on
March 1st, 1984, with the primary goal of providing a global archive of
satellite photos. The Landsat Program is managed by USGS, and data from Landsat
5 is collected and distributed from the USGS&apos;s Center for Earth Resources
Observation and Science (EROS).

Landsat 5 has significantly exceeded its designed life expectancy, and has a
maximum transmission bandwidth of 85 Mbit/s. It was deployed at an altitude of
705.3 km, a lower orbit than Landsat 4. It takes some 16 days to scan the
entire Earth. The satellite is an identical copy of Landsat 4 and was
originally intended as a backup - it therefore carries the same instruments,
including the Thematic Mapper and Multi-Spectral Scanner. The Multi-Spectral
Scanner was powered down in 1995.

Observation and Science (EROS).

Landsat 5 has significantly exceeded its designed life expectancy, and has a
maximum transmission bandwidth of 85 Mbit/s. It was deployed at an altitude of
705.3 km, a lower orbit than Landsat 4. It takes some 16 days to scan the
entire Earth. The satellite is an identical copy of Landsat 4 and was
originally intended as a backup - it therefore carries the same instruments,
including the Thematic Mapper and Multi-Spectral Scanner. The Multi-Spectral
Scanner was powered down in 1995.

    <skos:definition xml:lang="en">Gemini  12  was the tenth and final flight of the Gemini series, which bridged the Mercury and Apollo programs. This mission was scheduled to perform  rendezvous  and  docking  with  the  Agena target vehicle, to conduct three extravehicular activity (EVA) operations, and to conduct a  tethered  station keeping  exercise.  There were also 14 scientific, medical,  and  technological  experiments  on  board. The successfully performed  scientific  experiments  were  (1)  frog  egg  growth under zero-g,   (2)  synoptic  terrain  photography,  (3)  synoptic  weather photography,  (4)  nuclear emulsions, (5) airglow horizon photography, (6)  UV  astronomical  photography,  and  (7) dim sky photography. Two micrometeorite   collection   experiments,  as  well  as  three  space phenomena  photography  experiments,  were  not fully completed. There were  fuel  cell  and  attitude  control  thruster problems during the mission,   which   was   otherwise   highly  successful.  Reentry  was accomplished  after  59  orbits,  with  the spacecraft under automatic control.  It  landed  within  4.8  km  of the intended impact point on november 15, 1966.Group: Platform_Details   Entry_ID: GEMINI-12   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: GEMINI      Short_Name: GEMINI-12   End_Group   Group: Synonymous_Platform_Names      Short_Name: gemini-12   End_Group   Group: Orbit      Orbit_Inclination: 28.78 degrees      Perigee: 243 km      Apogee: 310 km   End_Group   Creation_Date: 2007-01-23   Online_Resource: http://www.astronautix.com/flights/gemini12.htm   Sample_Image: http://www.astronautix.com/graphics/0/10074584.jpg   Group: Platform_Logistics      Launch_Date: 1966-11-11      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">During the 10 day mission, the Space Radar Laboratory (SRL) payload in Endeavour&apos;s cargo bay will make its second flight. The SRL payload, which first flew during STS-59 in April 1994, will again give scientists highly detailed information that will help them distinguish between human-induced environmental changes and other natural forms of change.SRL-2 will take radar images of the Earth&apos;s surface for Earth system sciences studies, including geology, geography, hydrology, oceanography, agronomy and botany.The SRL payload is comprised of the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR), and the Measurement of Air Pollution from Satellite (MAPS). The German Space Agency (DARA) and the Italian Space Agency (ASI) are providing the X-SAR instrument.The imaging radar of the SIR-C/X-SAR instruments has the ability to make measurements over virtually any region at any time, regardless of weather or sunlight conditions. The radar waves can penetrate clouds, and under certain conditions, also can &apos;see&apos; through vegetation, ice and extremely dry sand. In many cases, radar is the only way scientists can explore inaccessible regions of the Earth&apos;s surface.The SIR-C/X-SAR radar data provide information about how many of Earth&apos;s complex systems - those processes that control the movement of land, water, air and life - work together to make this a livable planet. The science team particularly wants to study the amount of vegetation coverage, the extent of snow packs, wetlands areas, geologic features such as rock types and their distribution, volcanic activity, ocean wave heights and wind speed. STS-68 will fly over the same sites that STS-59 observed so that scientists will be able to study seasonal changes that may have occurred in those areas between the missions.An international team of 49 science investigators and three associates will conduct the SIR-C/X-SAR experiments. Thirteen nations are represented: Australia, Austria, Brazil, Canada, China, the United Kingdom, France, Germany, Italy, Japan, Mexico, Saudi Arabia and the United States.  The MAPS experiment will measure the global distribution of carbon monoxide in the troposphere, or lower atmosphere. Measurements of carbon monoxide, an important element in several chemical cycles, provide scientists with indications of how well the atmosphere can cleanse itself of &apos;greenhouse gases,&apos; chemicals that can increase the atmosphere&apos;s temperature.STS-68 provided a continuation of NASA&apos;s Get Away Special (GAS) experiments program. The project gives a person or organization a chance to perform experiments in space on a Shuttle mission. Two universities, North Carolina A&amp;T State University and University of Alabama in Huntsville, and the Swedish Space Corp., Soina, Sweden, will have small self-contained payloads flying during the STS-68 mission. Other GAS hardware in Endeavour&apos;s payload bay will carry 500,000 commemorative stamps for the U.S. Postal Service in recognition of the 25th anniversary of the Apollo 11 Moon landing.Other payloads aboard Endeavour include the Biological Research in Canister (BRIC) which will fly for the first time, and the Military Applications of Ship Tracks (MAST) which will be making its second flight. BRIC experiments, sponsored by NASA&apos;s Office of Life and Microgravity Sciences and Applications, are designed to examine the effects of microgravity on a wide range of physiological processes in higher order plants and arthropod animals (e.g., insects, spiders, centipedes, crustaceans). MAST is an experiment sponsored by the Office of Naval Research (ONR) and is part of a five-year research program developed by ONR to examine the effects of ships on the marine environment.The Commercial Protein Crystal Growth (CPCG) experiment, the Chromosome and Plant Cell Division in Space Experiment (CHROMEX) and the Cosmic Radiation Effects and Activation Monitor (CREAM) experiment also will be carried aboard Endeavour.[Summary provided by NASA]Group: Platform_Details   Entry_ID: STS-68   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: STS-68      Long_Name: Space Transport System STS-68   End_Group   Group: Synonymous_Platform_Names      Short_Name: Endeavour   End_Group   Group: Orbit      Orbit_Inclination: 57   End_Group   Creation_Date: 2008-01-30   Online_Resource: http://science.ksc.nasa.gov/shuttle/missions/sts-68/mission-sts-68.html   Sample_Image: http://www.nasa.gov/images/content/134508main_sts-68-crew-sm.jpg   Group: Platform_Logistics      Launch_Date: 1994-09-30      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

SORCE is a NASA-sponsored satellite mission that will provide state-of-the-art
measurements of incoming x-ray, ultraviolet, visible, near-infrared, and total
solar radiation. SORCE represents the merging of the EOS Solar Stellar
Irradiance Comparison Experiment (SOLSTICE) and the Total Solar Irradiance
Mission (TSIM). The measurements provided by SORCE specifically address
long-term climate change, natural variability and enhanced climate prediction,
and atmospheric ozone and UV-B radiation. These measurements are critical to
studies of the Sun, its effect on our Earth system, and its influence on
humankind.

Solar radiation is the dominant, direct energy input into the terrestrial
ecosystem, and it affects all physical, chemical, and biological processes. The
Sun provides a natural influence on the Earth&apos;s atmosphere and climate. In
order to understand mankind&apos;s roles in climate change, the Sun&apos;s impact must
first be understood.

SORCE measures the Sun&apos;s output with the use of state-of-the-art radiometers,
spectrometers, photodiodes, detectors, and bolometers engineered into
instruments mounted on a satellite observatory. The SORCE satellite orbits
around the Earth accumulating solar data. Spectral measurements identify the
irradiance of the Sun by characterizing the Sun&apos;s energy and emissions in the
form of color that can then be translated into quantities and elements of
matter. Data obtained by the SORCE experiment will be used to model the Sun&apos;s
output and to explain and predict the effect of the Sun&apos;s radiation on the
Earth&apos;s atmosphere and climate.

Old Value=SORCE is a NASA-sponsored satellite mission that will provide state-of-the-art measurements of incoming x-ray, ultraviolet, visible, near-infrared, and total solar radiation. SORCE represents the merging of the EOS Solar Stellar
Irradiance Comparison Experiment (SOLSTICE) and the Total Solar Irradiance Mission (TSIM). The measurements provided by SORCE specifically address long-term climate change, natural variability and enhanced climate prediction,
and atmospheric ozone and UV-B radiation. These measurements are critical to studies of the Sun, its effect on our Earth system, and its influence on humankind.

Solar radiation is the dominant, direct energy input into the terrestrial
ecosystem, and it affects all physical, chemical, and biological processes. The
Sun provides a natural influence on the Earth&apos;s atmosphere and climate. In
order to understand mankind&apos;s roles in climate change, the Sun&apos;s impact must
first be understood.

SORCE measures the Sun&apos;s output with the use of state-of-the-art radiometers,
spectrometers, photodiodes, detectors, and bolometers engineered into
instruments mounted on a satellite observatory. The SORCE satellite orbits
around the Earth accumulating solar data. Spectral measurements identify the
irradiance of the Sun by characterizing the Sun&apos;s energy and emissions in the
form of color that can then be translated into quantities and elements of
matter. Data obtained by the SORCE experiment will be used to model the Sun&apos;s
output and to explain and predict the effect of the Sun&apos;s radiation on the

    <skos:definition xml:lang="en">NOAA-4 was launched in November 1974 and was one in a series ofreconfigured ITOS satellites launched with new meteorological sensorsonboard to expand the operational capability of the ITOS system.  Theprimary objective was to provide global daytime and nighttime directreadout real-time cloudcover data on a daily basis. Thesun-synchronous spacecraft was also capable of supplying globalatmospheric temperature soundings and very high resolution infraredcloudcover data for selected areas in either a direct readout or atape-recorder mode. A secondary objective was to obtain globalsolar-proton flux data on a real-time daily basis. The sensors weremounted on the satellite baseplate with their optical axes directedvertically earthward. The nearly cubical spacecraft measured 1 by 1 by1.2 m. The satellite was equipped with three curved solar panels thatwere folded during launch and deployed after orbit was achieved. Eachpanel measured over 4.2 m in length when unfolded and was covered withapproximately 3500 solar cells measuring 2 by 2 cm. The dynamics andattitude control system maintained desired spacecraft orientationthrough gyroscopic principles incorporated into the satellitedesign. Earth orientation of the satellite body was maintained bytaking advantage of the precession induced from a momentum flywheel sothat the satellite body precession rate of one revolution per orbitprovided the desired &apos;earth-looking&apos; attitude. Minor adjustments inattitude and orientation were made by means of magnetic coils and byvarying the speed of the momentum flywheel.The primary sensors consisted of a Very High Resolution Radiometer(VHRR), Vertical Temperature Profile Radiometer (VTPR), and a ScanningRadiometer (SR).__________Taken from the NSSDC System for Information Retrieval and Storage (SIRS).

    <skos:definition xml:lang="en">OGO 2 was a large observatory instrumented with 20 experiments designed to make simultaneous, correlative observations of aurora and airglow emissions, energetic particles, magnetic field variations, ionospheric properties, etc., especially over the polar areas. OGO 2 consisted of a main body, generally parallelepipedal in form, two rectangular solar panels, each with a solar-oriented experiment package (SOEP), and two orbital plane experiment packages (OPEP). It also included six experiment packages (EP-1,-2,-3,-4,-5, and -6) mounted on booms extending generally fore and aft of the spacecraft along the Y axis. Antenna and attitude control fixtures also extended from separate and/or EP booms. The main body was attitude-controlled by use of horizon scanners and gas jets and was designed to point toward the earth (Z axis). The axis connecting the two solar panels (X axis) was designed to oscillate in order to remain perpendicular to the earth-sun-spacecraft plane. The solar panels activated by sun sensors could rotate about this X axis in order to obtain maximum radiation for the solar cells and concurrently orient the SOEP properly. The OPEPs were reoriented on either end of an axis that was parallel to the Z axis and attached to the forward end of the main body. These OPEP sensors normally were maintained looking forward in the orbital plane of the satellite. To maintain this orientation, the OPEP axis could rotate over 90 deg. In addition, an angular difference of over 90 deg was possible between the orientation of the upper and lower OPEP packages. The SOEP contained four experiments, and the OPEP contained five experiments. Soon after achieving orbit, difficulties in maintaining earth lock with horizon scanners caused exhaustion of attitude control gas by October 23, 1965, 10 days after launch. At this time, the spacecraft entered a spin mode (about 0.11 rpm) with a large coning angle about the previously vertical axis. Five experiments became useless when the satellite went into this spin mode. Six additional experiments were degraded by this loss of attitude control. By April 1966, both batteries had failed, so subsequent observations were limited to sunlit portions of the orbit. By December 1966, only eight experiments were operational, five of which were not degraded by the spin mode operation. By April 1967, the tape recorders had malfunctioned and only one third of the recorded data could be processed. Spacecraft power and periods of operational scheduling conflicts created six large data gaps so that data were observed on a total of about 306 days of the 2-yr, 18-day total span of observed satellite data to November 1, 1967. The data gaps were (a) October 24, 1965, to November 5, 1965, (b) December 6, 1965, to January 7, 1966, (c) April 9, 1966, to June 21, 1966, (d) September 2, 1966, to November 18, 1966, (e) December 27, 1966, to April 11, 1967, and (f) May 9, 1967, to September 19, 1967. The spacecraft was shut down on November 1, 1967, with eight experiments still operational. It was reactivated for 2 weeks in February 1968 to operate experiment 65-081A-05.

    <skos:definition xml:lang="en">The Orbiting Geophysical Observatory 6 (OGO 6) was a large observatoryinstrumented with 26 experiments designed to study the variousinterrelationships between, and latitudinal distributions of, high-altitudeatmospheric parameters during a period of increased solar activity. The mainbody of the spacecraft was attitude controlled by means of horizon scanners andgas jets so that its orientation was maintained constant with respect to theearth and the sun. The solar panels rotated on a horizontal axis extendingtransversely through the main body of the spacecraft. The rotation of thepanels was activated by sun sensors so that the panels received maximumsunlight. Seven experiments were mounted on the solar panels (the SOEPpackage). An additional axis, oriented vertically across the front of the mainbody, carried seven experiments (the OPEP package). Nominally, these sensorsobserved in a forward direction in the orbital plane of the satellite. Thesensors could be rotated more than 90 deg relative to the nominal observingposition and more than 90 deg between the upper and lower OPEP groups mountedon either end of this axis. On June 22, 1969, the spacecraft potential droppedsignificantly during sunlight operation and remained so during subsequentsunlight operation. This unexplained shift affected seven experiments whichmade measurements dependent upon knowledge of the spacecraft plasma sheath.During October 1969, a string of solar cells failed, but the only effect of thedecreased power was to cause two experiments to change their mode of operation.Also during October 1969, a combination of manual and automatic attitudecontrol was initiated, which extended the control gas lifetime of the attitudecontrol system. In August 1970, tape recorder (TR) no. 1 operation degraded, soall recorded data were subsequently taken with TR no. 2. By September 1970,power and equipment degradation left 14 experiments operating normally, 3partially, and 9 off. From October 14, 1970, TR no. 2 was used only onWednesdays (world days) to conserve power and extend TR operation. In June1971, the number of &apos;on&apos; experiments decreased from 13 to 7, and on June 28,1971, the spacecraft was placed in a spin-stabilized mode about the yaw (Z)axis and turned off due to difficulties with spacecraft power. OGO 6 was turnedon again from October 10, 1971, through March 1972, for operation of experiment25 by The Radio Research Laboratory, Japan.

The MOS-1bcarried the same three sensors as the MOS-1a: a Multi-spectrumElectronic Self-Scanning Radiometer (MESSR), a Visible and ThermalInfrared Radiometer (VTIR), and a Microwave Scanning Radiometer(MSR). Data was transmitted real-time to the Hatoyama EarthObservation Center for processing and is available through the DataService Department, Remote Sensing Technology Center of Japan(RESTEC). The satellite also included a Data Collection System (DCS)Transponder designed to be a forerunner of the Japanese TDRSS, used tocollect and relay information from surface Data Collection Platforms(DCPs) and locate DCPs based on the Doppler frequency of receivedsignals. The satellite is a 1.26 x 1.48 x 2.4 meter high box-shape ofaluminium honeycomb construction with a single solar array of three1.51 meter wide panels. The satellite is controlled in three axes bymomentum wheels and four IN hydrazine thrusters. Other MOS satellitesare planned throughout the 1990&apos;s.                  - Auxiliary Information -    Launch Date and Time :  1990-02-07    Epoch Date and Time  :    Apogee (km or AU):      940.

    <skos:definition xml:lang="en">SMS-1 was launched in May 1974 and was a NASA-developed, NOAA-operated, prototype spacecraft for the geosynchronous series of meteorological satellites.  The cylindrically shaped spacecraft measured 190.5 cm in diameter and 230 cm in length, exclusive of a magnetometer that extended an additional 83 cm beyond the cylinder shell.  The primary structural members were a honeycombed equipment shelf and thrust tube.  The VISSR telescope was mounted on the equipment shelf and viewed the Earth through a special aperture in the side of the spacecraft.  A support structure extended radially from the thrust tube and was affixed to the solar panels, which formed the outer walls of the spacecraft and provided the primary source of electrical power.  Located in the annulus-shaped space between the thrust tube and the solar panels were stationkeeping and dynamics control equipment, batteries, and most of the SEM equipment.  Proper spacecraft attitude and spin rate (approximately 100 rpm) were maintained by two separate sets of jet thrusters mounted around the spacecraft equator and activated by ground command.  The spacecraft used both UHF-band and S-band frequencies in its telemetry and command subsystem.  A low-power VHF transponder provided telemetry and command during launch and then served as a backup for the primary subsystem once the spacecraft attained orbit. This spin-stabilized spacecraft carried a visible infrared spin-scan radiometer, meteorological data collection and relay system, space environment monitor, and a biaxial fluxgate magnetometer.  Throughout its 7 year history, it operated at 45, 75 and 92 degrees West.__________Taken from the NSSDC System for Information Retrieval and Storage (SIRS).

Old Value=Landsat 1, originally named Earth Resources Technology Satellite 1, was a
modified version of the Nimbus 4 meteorological satellite. It was launched on
July 23, 1972, the first satellite of the United States&apos; Landsat program. The
near-polar orbiting spacecraft served as a stabilized, Earth-oriented platform
for obtaining information on agricultural and forestry resources, geology and
mineral resources, hydrology and water resources, geography, cartography,
environmental pollution, oceanography and marine resources, and meteorological
phenomena.

To accomplish these objectives, the spacecraft was equipped with (1) a
three-camera return beam vidicon (RBV) to obtain visible light and near
infrared photographic images of Earth, (2) a four-channel multispectral scanner
(MSS) to obtain radiometric images of Earth, and (3) a data collection system
(DCS) to collect information from remote, individually equipped ground stations
and to relay the data to central acquisition stations. Landsat 1 carried two
wide-band video tape recorders (WBVTR) capable of storing up to 30 min of
scanner or camera data to give the spacecraft&apos;s sensors a near-global coverage
capability.

An advanced attitude control system consisting of horizon scanners, sun
sensors, and a command antenna combined with a freon gas propulsion system
permitted the spacecraft&apos;s orientation to be maintained within plus or minus
0.7 degrees in all three axes. Spacecraft communications included a command
subsystem operating at 154.2 and 2106.4 MHz and a PCM narrow-band telemetry
subsystem, operating at 2287.5 and 137.86 MHz, for spacecraft housekeeping,
attitude, and sensor performance data. Video data from the three-camera RBV
system was transmitted in both real-time and tape recorder modes at 2265.5 MHz,
while information from the MSS was constrained to a 20 MHz rf bandwidth at
2229.5 MHz.

In 1976, Landsat 1 discovered a tiny uninhabited island 20 km off the eastern
coast of Canada. This island was thereafter designated Landsat Island after the
satellite. As of 2006, it is the only island to be discovered via satellite
imagery.

The spacecraft was turned off on January 6, 1978, when cumulative precession of
the orbital plane caused the spacecraft to see almost constant sunlight which
led to overheating.

text: Annie is a 40’ long aluminum research vessel that was designed and built to support many types of science and exploration-related tasks.  She is powered by twin diesels coupled to very powerful jet drives and is uniquely outfitted with complete station keeping capability.  Lacking the need to anchor, she is an ideal platform for Remotely Operated Vehicle (ROV) operations. Additionally, Annie is ideally equipped for side-scan and multibeam sonar projects, gravity coring, or any other sensor deployments with no anchoring required.

The vessel is also designed to be deployed in remote locations, using a heavy-lift helicopter or from larger ships such as ice breakers using ship-mounted cargo cranes.  The cabin is uniquely set up as a fully climate controlled control room with significant console workspace and room for rack-mounting electronics.  Interior custom framework facilitates the mounting of a large array of high definition video and computer monitors, as well as navigation and audio equipment.

She is currently being used for research in Yellowstone Lake, supporting Autonomous Underwater Vehicle (AUV), ROV and multiple coring and sensor deployments, but can easily be trailered to other areas of interest.  Annie is named after the first vessel to sail on Yellowstone Lake during the Hayden Expedition in 1871

    <skos:definition xml:lang="en">The STS-64 mission will carry the LIDAR In-Space Technology Experiment (LITE), a project to measure atmospheric parameters from a space platform utilizing laser sensors, the Robot Operated Materials Processing System (ROMPS) to investigate robot handling of thin film samples, and the Shuttle Pointed Autonomous Research Tool for Astronomy (SPARTAN-201). SPARTAN is a free-flying retrievable platform with two telescopes to study the solar wind, a continuous stream of electrons, heavy protons and heavy ions ejected from the sun and traveling through space at speeds of almost 1 million miles per hour. The solar wind frequently causes problems on Earth by disrupting navigation, communications and electrical power.The STS-64 mission will also carry the Shuttle Plume Impingement Flight Experiment (SPIFEX). This experiment is designed to directly measure RCS plume loads in the far-field regime under actual on-orbit conditions. Discovery&apos;s payload bay also contains a GAS bridge assembly with 12 GAS canisters (G-178, G-254, G-312, G-325, G-417, G-453, G-454, G-456, G-485, G-506 and G-562). One additional experiment in the payload bay is the Trajectory Control Sensor (TCS) package positioned on an Adaptive Payload Carrier. It will provide relative trajectory data on a target vehicle operating in close proximity (less than 5000ft) of the Orbiter. The TCS will provide range and range rate data for target vehicles having a reflective surface. Additionally, the TCS provides bearing, bearing rate, attitude, and attitude rates for target vehicles utilizing special retro-reflectors.In Discovery&apos;s middeck area, STS-64 will carry the Simplified Aid for EVA Rescue (SAFER) system, the Solid Surface Combustion Experiment (SSCE), the Biological Research in Canister III (BRIC-III) experiment, the Radiation Monitoring Equipment III (RME-III) experiment. Other experiments onboard STS-64 include Military Application of Ship Trails (MAST), Shuttle Amateur Radio Experiment-II (SAREX-II) and Air Force Maui Optical Site Calibration Test (AMOS).[Summary provided by NASA]Group: Platform_Details   Entry_ID: STS-64   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: STS-64      Long_Name: Space Transport System STS-64   End_Group   Group: Synonymous_Platform_Names      Short_Name: Discovery   End_Group   Group: Orbit      Orbit_Altitude: 140 nm      Orbit_Inclination: 57 degrees   End_Group   Creation_Date: 2008-01-30   Online_Resource: http://science.ksc.nasa.gov/shuttle/missions/sts-64/mission-sts-64.html   Sample_Image: http://www.nasa.gov/images/content/134500main_sts-64-crew-sm.jpg   Group: Platform_Logistics      Launch_Date: 1994-09-09      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The primary objective of the STS-99 mission was to complete high resolution mapping of large sections of the Earth&apos;s surface using the Shuttle Radar Topography Mission (SRTM), a specially modified radar system. This radar system produced unrivaled 3-D images of the Earth&apos;s Surface. The mission was launched at 1231 on February 11, 2000 onboard the space shuttle Endeavour, and led by Commander Kevin Kregel. The crew was Pilot Dominic L. Pudwill Gorie and Mission Specialists Janet L. Kavandi, Janice E. Voss, Mamoru Mohri from the National Space Development Agency (Japanese Space Agency), and Gerhard P. J. Thiele from DARA (German Space Agency). This videotape shows a press briefing about a mechanical problem that the shuttle was having. There was discussion about possibly scrubbing the launch due to the problem with the Enhanced Master Events Controller. A problem with a fuel pump part had also become evident and there was discussion about the impact that this could have on the flight.

text: Landsat 9—a partnership between NASA and the U.S. Geological Survey— will continue the Landsat program’s critical role in monitoring, understanding and managing the land resources needed to sustain human life.

Today’s increased rates of global land cover and land use change have profound consequences for weather and climate change, ecosystem function and services, carbon cycling and sequestration, resource management, the national and global economy, human health, and society.

Landsat is the only U.S. satellite system designed and operated to repeatedly observe the global land surface at a moderate scale that shows both natural and human-induced change.

Landsat 9 has been fast-tracked for a December 2020 launch.

Old Value=Landsat 7 systematically provides well-calibrated, multispectral, moderate resolution, substantially cloud-free, sun-lit digital images of the Earth&apos;s continental and coastal areas with global coverage on a seasonal basis. It covers the United States every 16 days. Operations were transferred to USGS on Fall 2000.

The Landsat Project is a joint initiative of the U.S. Geological Survey (USGS) and the NASA to gather Earth resource data using a series of satellites. NASA was responsible for developing and launching the spacecrafts, while the USGS is responsible for flight operations, maintenance, and management of all ground data reception, processing, archiving, product generation, and distribution.

The primary objective of the Landsat Project is to ensure a collection of consistently calibrated Earth imagery. Landsat&apos;s Global Survey Mission is to establish and execute a data acquisition strategy that ensures repetitive acquisition of observations over the Earth&apos;s land mass, coastal boundaries, and coral reefs; and to ensure the data acquired are of maximum utility in supporting the scientific objectives of monitoring changes in the Earth&apos;s land surface and associated environment.

New Value=Landsat 7 systematically provides well-calibrated, multispectral, moderate resolution, substantially cloud-free, sun-lit digital images of the Earth&apos;s continental and coastal areas with global coverage on a seasonal basis. It covers the United States every 16 days. Operations were transferred to USGS on Fall 2000.

The Landsat Project is a joint initiative of the U.S. Geological Survey (USGS) and the NASA to gather Earth resource data using a series of satellites. NASA was responsible for developing and launching the spacecrafts, while the USGS is responsible for flight operations, maintenance, and management of all ground data reception, processing, archiving, product generation, and distribution.

The primary objective of the Landsat Project is to ensure a collection of consistently calibrated Earth imagery. Landsat&apos;s Global Survey Mission is to establish and execute a data acquisition strategy that ensures repetitive acquisition of observations over the Earth&apos;s land mass, coastal boundaries, and coral reefs; and to ensure the data acquired are of maximum utility in supporting the scientific objectives of monitoring changes in the Earth&apos;s land surface and associated environment.

Old Value=Orbiting Carbon Observatory – 3 (OCO-3) is a complete stand-alone payload built using the spare OCO-2 flight instrument, with additional elements added to accommodate installation and operation on the International Space Station (ISS).  More Information: https://science.nasa.gov/missions/oco-3
New Value=Orbiting Carbon Observatory-3 (OCO-3) will be flying on the International Space Station (ISS) and will continue the important measurement begun by OCO-2 in 2014. Some quick facts about OCO-3 are:

- OCO-3 is a critical element in the continuation of global carbon dioxide (CO2) measurements focused on understanding the regional sources and sinks of CO2 from the unique vantage point of the International Space Station (ISS).

- OCO-3 can also contribute to focused studies of how space based measurements can constrain rapidly changing anthropogenic (man-made) emissions. Anthropogenic emissions could be the largest source of uncertainty in the global carbon budget as OCO-3 measurements reduce uncertainty of natural fluxes. OCO-3 has the ability to makes measurements at different times of the day.

- OCO-3 measurements can be combined with evapotranspiration and biomass measurements, such as those from other ISS instruments ECOSTRESS and GEDI, to study process details of the terrestrial ecosystem.

- OCO-2 has demonstrated that atmospheric XCO2 can be measured from space with precision of better than 1 ppm. OCO-3 is expected to have similar performance.

Old Value=Landsat 3 is the third satellite of the Landsat program. It was launched on
March 5th, 1978, with the primary goal of providing a global archive of
satellite photos. Unlike later Landsats, Landsat 3 was managed solely by NASA.
Landsat 3 is no longer in operation, due to technical failure. It finally
ceased transmission on March 21st 1983, far beyond its designed life expectancy
of one year.

Landsat 3 had essentially the same design as Landsat 2. It carried a
Multi-Spectral Scanner, which had a maximum 75m resolution. Unlike the previous
two Landsat missions a thermal band was built into Landsat 3, but this
instrument failed shortly after the satellite was deployed. [2] Landsat 3 was
placed into a polar orbit at about 920 kilometers, and took 18 days to cover
the entire Earth&apos;s surface.

    <skos:definition xml:lang="en">Landsat 3 is the third satellite of the Landsat program. It was launched onMarch 5th, 1978, with the primary goal of providing a global archive ofsatellite photos. Unlike later Landsats, Landsat 3 was managed solely by NASA.Landsat 3 is no longer in operation, due to technical failure. It finallyceased transmission on March 21st 1983, far beyond its designed life expectancyof one year.Landsat 3 had essentially the same design as Landsat 2. It carried aMulti-Spectral Scanner, which had a maximum 75m resolution. Unlike the previoustwo Landsat missions a thermal band was built into Landsat 3, but thisinstrument failed shortly after the satellite was deployed. [2] Landsat 3 wasplaced into a polar orbit at about 920 kilometers, and took 18 days to coverthe entire Earth&amp;#039;s surface.

text: ATLAS missions were part of Phase I of NASA&apos;s Mission to Planet Earth, a large-scale, unified study of planet Earth as a single, dynamic system. Throughout the ATLAS series, scientists gathered new information to gain a better understanding of how the atmosphere reacts to natural and human-induced atmospheric changes. That knowledge helped us identify measures to keep our planet suitable for life for future generations.

ATLAS-1 flew aboard Space Shuttle Atlantis on mission STS-45 in spring 1992. It was the first of up to nine ATLAS missions that were undertaken throughout one solar cycle, which lasted 11 years. During that period solar flares, sunspots and other magnetic activity in the sun changes from one extreme to the other and back.

    <skos:definition xml:lang="en">The Global Position System (GPS), counterpart to the Russian Global NavigationSystem (GLONASS), is a United States Department of Defense (DoD) developed,worldwide, satellite-based radionavigation system that will be the DoD&apos;sprimary radionavigation system well into the next century. The constellationconsists of 24 operational satellites. The U.S. Air Force Space Command (AFSC)formally declared the GPS satellite constellation as having met the requirementfor Full Operational Capability (FOC) as of April 27, 1995. Requirementsinclude 24 operational satellites functioning in their assigned orbits andsuccessful testing completed for operational military functionality.GPS consists of three segments, the SPACE, CONTROL and USER Segment:1. The SPACE segment consists of 24 operational satellites in six orbitalplanes, (four satellites in each plane). The satellites operate in circular20,200 km orbits at an inclination angle of 55 degrees and with a 12-hourperiod. The position is therefore the same at the same sidereal time each day,i.e. the satellites appear four minutes earlier each day.2. The CONTROL segment consists of five Monitor Stations, three GroundAntennas, and a Master Control Station (MCS) located at Falcon AFB in Colorado.The monitor stations passively track all satellites in view, accumulatingranging data. This information is processed at the MCS to determine satelliteorbits and to update each satellite&apos;s navigation message. Updated informationis transmitted to each satellite via the Ground Antennas.3. The USER segment consists of antennas and receiver-processors thatprovide positioning, velocity and precise timing to the user.GPS provides two levels of service, Standard Positioning Service and thePrecise Positioning Service. The Standard Positioning Service (SPS) is apositioning and timing service which will be available to all GPS users on acontinuous, worldwide basis with no direct charge. The Precise PositioningService (PPS) is a highly accurate military positioning, velocity and timingservice which will be available on a continuous, worldwide basis to usersauthorized by the U.S. [Summary provided by NASA.]Group: Platform_Details   Entry_ID: GPS-36   Group: Platform_Identification      Platform_Category: Navigation Platforms      Platform_Series_or_Entity: GPS (Global Positioning System)      Short_Name: GPS-36      Long_Name: Global Positioning System Satellites-36   End_Group   Group: Platform_Associated_Instruments      Short_Name: GPS      Short_Name: GPS RECEIVERS   End_Group   Group: Orbit      Orbit_Altitude: 20,200 km      Orbit_Inclination: 64.8 degrees      Period: 718 minutes      Perigee: 20,030 km      Orbit_Type: MEO &gt; Semi-Synchronous &gt; Navigation   End_Group   Creation_Date: 2007-02-12   Online_Resource: http://ilrs.gsfc.nasa.gov/cgi-bin/satellite_missions/select.cgi?order=by_name&amp;sat_code=GP36&amp;sat_name=GPS-36&amp;sat_no=9401601&amp;tab_id=general   Sample_Image: http://ilrs.gsfc.nasa.gov/images/gps.gif   Group: Platform_Logistics      Launch_Date: 1994-04-10      Primary_Sponsor: U.S. Department of Defense    End_GroupEnd_Group</skos:definition>

text: The second flight in a series of Space Shuttle-Spacelab missions, designated the Atmospheric Laboratory for Applications and Science (ATLAS), was part of NASA&apos;s Mission to Planet Earth. The first ATLAS was flown on STS 45 in March 1992. The ATLAS series was intended to study the composition of the middle atmosphere and its possible variations due to solar changes over the course of an 11-year solar cycle. The second flight of ATLAS focused on atmospheric and solar physics studies and did not include the experiments on space plasma physics and astronomy that were flown with the ATLAS 1 payload. The ATLAS 2 instruments were mounted on Spacelab pallets (provided by ESA) in the Shuttle payload bay. The ATLAS 2 instrument power supply, command and data handling system and temperature control systems were housed in a pressurized container called an igloo located in front of the pallet. The Shuttle&apos;s changing orientation to Earth placed the experiments in advantageous orbiting locations to observe the atmosphere and the Sun. The Shuttle orbiter orientation was either inertially fixed so that selected instruments were pointed at the Sun, or nadir pointed for observations of the Earth&apos;s atmosphere. Crew members were in consultation with the investigators while controlling and monitoring the experiments. The atmospheric and solar instrument data were also used to provide correlative measurements with the Upper Atmosphere Research Satellite (UARS) and the Solar-Backscattered Ultraviolet (SBUV/2) instruments on board the NOAA polar orbiters. The ATLAS 2 core instruments consisted of: (1) Active Cavity Radiometer Irradiance Monitor (ACRIM); (2) Measurement of the Solar Constant (SOLCON); (3) Solar Spectrum Measurement (SOLSPEC); (4) Solar Ultraviolet Spectral Irradiance Monitor (SUSIM); (5) Atmospheric Trace Molecule Spectroscopy (ATMOS); and, (6) Millimeter-Wave Atmospheric Sounder (MAS). The ATLAS 2 payload was co-manifested with the Shuttle Solar Backscatter Ultraviolet (SSBUV 05) experiment and integrated into the ATLAS Science Plan.

    <skos:definition xml:lang="en">Scientists around the world will be provided a unique vantage point for studying how the Earth&apos;s global environment is changing when Space Shuttle Endeavour is launched on Shuttle mission STS-59. During the 9-day mission, the Space Radar Laboratory (SRL) payload in Endeavour&apos;s cargo bay will give scientists highly detailed information that will help them distinguish human-induced environmental changes from other natural forms of change.The Space Radar Laboratory (SRL) payload is comprised of the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) and the Measurement of Air Pollution from Satellite (MAPS). The German Space Agency (DARA) and the Italian Space Agency (ASI) are providing the X-SAR instrument. The imaging radar of the SIR-C/X-SAR instruments have the ability to make measurements over virtually any region at any time, regardless of weather or sunlight conditions. The radar waves can penetrate clouds, and under certain conditions, can also &apos;see&apos; through vegetation, ice and extremely dry sand. In many cases, radar is the only way scientists can explore inaccessible regions of the Earth&apos;s surface.[Summary provided by NASA]Group: Platform_Details   Entry_ID: STS-59   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: STS-59      Long_Name: Space Transport System STS-59   End_Group   Group: Synonymous_Platform_Names      Short_Name: Endeavour   End_Group   Group: Orbit      Orbit_Altitude: 121nm      Orbit_Inclination: 57 degrees   End_Group   Creation_Date: 2008-01-30   Online_Resource: http://science.ksc.nasa.gov/shuttle/missions/sts-59/mission-sts-59.html   Sample_Image: http://www.nasa.gov/images/content/136249main_sts-59-crew-sm.jpg   Group: Platform_Logistics      Launch_Date: 1994-04-09      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The SPAS (Shuttle Pallet Satellite) satellite was a reusable free-flying vehicle built by Messerschmitt-Bolkow-Blohm.which could be deployed and then retrieved by the US Space Shuttle&apos;s Remote Manipulator System arm. The original SPAS, with materials processing and SDI-related sensor payloads, was used on several missions (STS-7, STS-11, STS-39). An experiment-carrying truss (USS) based on the original SPAS structure (but without the avionics and attitude control) was flown on the Spacelab D-1 and D-2 missions.The shuttle was launched on April 28, 1991 and landed May 6, 1991. Unclassified payload included the Infrared Background Signature Survey (IBSS) with Critical Ionization Velocity (CIV), Chemical Release Observation (CRO) and Shuttle Pallet Satellite-II (SPAS-II) experiments; and Space Test Payload-1 (STP-1). Classified payload consisted of Multi-Purpose Release Canister (MPEC).

    <skos:definition xml:lang="en">The Indian Remote Sensing Satellite-1B (IRS-1B) was launched on August 8, 1991, from Tyuratan, U.S.S.R..  IRS-1B continues the series of Earth resources remote sensing satellites developed by Indian Space Research Organisation (ISRO) for land-based applications such as agriculture, forestry, geology, and hydrology. The spacecraft is a box-shaped 1.6 x 1.56 x 1.1 meter bus with two Sun-tracking solar arrays of 8.5 square meters each. Two nickel cadmium batteries provide power during eclipses. The three-axis stabilize sun-synchronous satellite had a 0.4 degree pitch/roll and 0.5 degree yaw pointing accuracy provided by a zero-momentum reaction wheel system utilizing Earth/Sun/star sensors and gyros. The satellite carried three Linear Imaging Self-Scanning (LISS) push-broom CCD sensors operating in four spectral bands compatible with Landsat Thematic Mapper and Spor HRV data. The bands were 0.45 - 0.52, 0.52 - 0.59, 0.62 - 0.68, and 0.77 - 0.86 microns. The LISS 1 sensor had four 2048-element CCD imagers with a focal length of 162.2 cm generating a resolution of 72.5 meters and a 148 km swath width. The LISS 2A/B sensors had eight 2048-element CCD imagers with a focal length of 324.4 mm generating a ground resolution of 36.25 meters and a 74 km swath width. The two LISS 2 imagers bracketed the LISS 1 imager providing a 3 km overlap. Data from the LISS 1 were downlinked on S-band at 5.2 Mbps and from the LISS 2 A/B at 10.4 Mbps to the ground station at Shandnager, India. The satellite was controlled from Bangalore, India.Group: Platform_Details   Entry_ID: IRS-1B   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: IRS (Indian Remote Sensing Satellite)      Short_Name: IRS-1B      Long_Name: Indian Remote Sensing Satellite-1B   End_Group   Group: Synonymous_Platform_Names      Short_Name: IRS-IB   End_Group   Group: Platform_Associated_Instruments      Short_Name: LISS-I      Short_Name: LISS-II   End_Group   Group: Orbit      Orbit_Altitude: 904 km      Orbit_Inclination: 99 deg      Period: 103 min      Repeat_Cycle: 22 days      Perigee: 887 km      Apogee: 922 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-10-05   Online_Resource: http://www.isro.gov.in/satellites/irs-1b.aspx   Sample_Image: http://www.isro.gov.in/satellites/images/irs-1b_img.gif   Group: Platform_Logistics      Launch_Date: 1991-08-08      Launch_Site: Baikonur Cosmodrome, Tyuratam, Russia      Primary_Sponsor: India   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">Columbia, the oldest orbiter in the Shuttle fleet, is named after the Boston, Massachusetts based sloop captained by American Robert Gray. The spaceship Columbia has continued the pioneering legacy of its forebears, becoming the first Space Shuttle to fly into Earth orbit in 1981. Four sister ships joined the fleet over the next 10 years: Challenger, arriving in 1982 but destroyed four years later; Discovery, 1983; Atlantis, 1985; and Endeavour, built as a replacement for Challenger, 1991. A test vehicle, the Enterprise, was used for suborbital approach and landing tests and did not fly in space.Columbia was the first on-line orbiter to undergo the scheduled inspection and retrofit program. It was transported August 10, 1991, after its completion of mission STS-40, to prime Shuttle contractor Rockwell International&apos;s Palmdale, California assembly plant. The oldest orbiter in the fleet underwent approximately 50 modifications, including the addition of carbon brakes, drag chute, improved nose wheel steering, removal of development flight instrumentation and an enhancement of its thermal protection system. The orbiter returned to KSC February 9, 1992 to begin processing for mission STS-50 in June of that year.On October 8, 1994, Columbia was transported to Palmdale California for its first ODMP. Approximately 90 modifications and upgrades were made to Columbia during this 6 month period. Modifications included upgrades to the main landing gear thermal barrier, tire pressure monitoring system and radiator drive circuitry. (Reference KSC Press Release 113-94 and Shuttle Status Report 10/10/94)On September 24, 1999, Columbia was transported to Palmdale California for its second ODMP. While in California, workers will perform more than 100 modifications on the vehicle. Columbia will be the second orbiter outfitted with the multi-functional electronic display system (MEDS) or &apos;glass cockpit&apos;. Last year, Shuttle Atlantis had the full-color, flat-panel displays installed on its flight deck during an OMDP. The new system improves crew interaction with the orbiter during flight and reduces the high cost of maintaining the outdated electromechanical cockpit displays currently onboard. (Reference KSC Press Release 74-99).On February 1, 2003, Columbia was lost during re-entry into Earth&apos;s atmosphere.

    <skos:definition xml:lang="en">The Space Shuttle Discover was the the third orbiter to become operational at Kennedy Space Center, was named after one of two ships that were used by the British explorer James Cook in the 1770s during voyages in the South Pacific that led to the discovery of the Hawaiian Islands. Another of his ships was the Endeavour, the namesake of NASA&apos;s newest orbiter.Discovery benefited from lessons learned in the construction and testing of Enterprise, Columbia and Challenger. At rollout, its weight was some 6,870 pounds less than Columbia. Two orbiters, Challenger and Discovery, were modified at KSC to enable them to carry the Centaur upper stage in the payload bay. These modifications included extra plumbing to load and vent Centaur&apos;s cryogenic (L02/LH2) propellants (other IUS/PAM upper stages use solid propellants), and controls on the aft flight deck for loading and monitoring the Centaur stage. No Centaur flight was ever flown and after the loss of Challenger it was decided that the risk was too great to launch a shuttle with a fueled Centaur upper stage in the payload bay.[Summary provided by NASA]Group: Platform_Details   Entry_ID: OV-103   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: OV-103      Long_Name: Discovery Space Shuttle   End_Group   Group: Synonymous_Platform_Names      Short_Name: Discovery   End_Group   Creation_Date: 2008-01-25   Online_Resource: http://science.ksc.nasa.gov/shuttle/resources/orbiters/discovery.html   Sample_Image: http://science.ksc.nasa.gov/shuttle/resources/orbiters/discovery-logo.gif   Group: Platform_Logistics      Launch_Date: 1984-08-30      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The Atmospheric Laboratory for Applications and Sciences - 3 (ATLAS-03) is the primary payload aboard STS-66. It will continue the series of Spacelab flights to study the energy of the sun and how it affects the Earth&apos;s climate and environment. The ATLAS 3 mission will make the first detailed measurements from the Shuttle of the Northern Hemisphere&apos;s middle atmosphere in late fall. The timing of the flight, when the Antarctic ozone hole is diminishing, allows scientists to study possible effects of the ozone hole on mid-latitudes, the way Antarctic air recovers, and how the northern atmosphere changes as the winter season approaches.In addition to the ATLAS-03 investigations, the mission will include deployment and retrieval of the Cryogenic Infrared Spectrometer Telescopefor Atmosphere, or CRISTA. Mounted on the Shuttle Pallet Satellite, the payload is designed to explore the variability of the atmosphere and provide measurements that will complement those obtained by the Upper Atmosphere Research Satellite launched aboard Discovery in 1991. CRISTA-SPAS is a joint U.S./German experiment.Other payloads in Atlantis cargo bay include the Shuttle Solar Backscatter Ultraviolet (SSBUV-7) payload and the Experiment on the Sun Complementing ATLAS (ESCAPE-II). Payloads located in the middeck include the Physiological &amp; Anatomical Rodent Experiment (PARE/NIR-R), Protein Crystal Growth-Thermal Enclosure (PCG-TES), Protein Crystal Growth- Single Locker (PCG-STES), Space Tissue Loss/National Institute of Health (STL/NIH-C), Space Acceleration Measurement System (SAMS) and the Heat Pipe Performance-2 Experiment (HPP-2).[Summary provided by NASA]Group: Platform_Details   Entry_ID: STS-66   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: STS-66      Long_Name: Space Transport System STS-66   End_Group   Group: Synonymous_Platform_Names      Short_Name: Atlantis   End_Group   Group: Orbit      Orbit_Altitude: 164nm      Orbit_Inclination: 57 degrees   End_Group   Creation_Date: 2008-01-30   Online_Resource: http://science.ksc.nasa.gov/shuttle/missions/sts-66/mission-sts-66.html   Sample_Image: http://www.nasa.gov/images/content/134504main_sts-66-crew-sm.jpg   Group: Platform_Logistics      Launch_Date: 1994-11-03      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The first dedicated mission with acquisition of science data as its primary objective, Spacelab 3 was a multidisciplinary mission emphasizing investigations requiring the low-gravity environment of Earth orbit. The experiments covered several disciplines. For the materials processing discipline, higher-quality crystals were grown by two methods; namely, seed crystal growth in a saturated solution and condensation from the vapor phase. The two fluid physics experiments studied the dynamic behavior of rotating and oscillating liquid drops, and the convection processes found in planetary atmospheres and in stellar interiors. The performance of equipment and facilities specially designed for investigations on the Spacelab Life Sciences mission series was evaluated. The investigations selected for the Spacelab 3 mission originated in the United States, France, and India, and represented a total of five different disciplines, including material science, life sciences, fluid mechanics, atmospheric science, and astronomy. Two of the investigations, one in material science and one in astronomy, had already flown aboard Spacelab 1. Many of the Spacelab 3 investigations were scheduled to be modified and reflown on later missions to further explore the discoveries of this mission. Some of the experiments were located in the module, some on the pallet in the payload bay, and one at middeck. Spacelab 3 consisted of a Spacelab long module and a pallet. The mission successfully demonstrated the capability of Spacelab for multidiscipline research in microgravity.[Summary provided by NASA.]Group: Platform_Details   Entry_ID: STS-51B   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: STS-51B      Long_Name: Space Transport System STS-51B   End_Group   Group: Synonymous_Platform_Names      Short_Name: Challenger   End_Group   Group: Orbit      Orbit_Inclination: 28.45 degrees      Perigee: 370 km      Apogee: 370 km   End_Group   Creation_Date: 2008-01-29   Online_Resource: http://science.ksc.nasa.gov/shuttle/missions/sts-51/mission-sts-51.html   Sample_Image: http://www.nasa.gov/images/content/134455main_sts-51b-crew-sm.jpg   Group: Platform_Logistics      Launch_Date: 1985-04-29      Launch_Site: Cape Canaveral/Kennedy Space Center, USA      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

This necessitated moving the vehicle back to the Vehicle Assembly Building where the nozzle was replaced.The 6-member crew -- a manned space flight record at the time -- included John W. Young, commander, on his second Shuttle flight; Brewster H. Shaw, pilot; Owen Garriott and Robert A. Parker, both mission specialists; and Byron K. Lichtenberg and Ulf Merbold payload specialists -- the first two non-astronauts to fly on the Shuttle. Merbold, a citizen of West Germany, also was the first foreign citizen to participate in a Shuttle flight.

language code: en</skos:changeNote>
    <skos:definition xml:lang="en">The second European Remote Sensing Satellite ERS-2, launched on 20April 1995, operates in a sun-synchronous, near-polar orbit at analtitude of 785 km and an inclination of 98.5 degrees ,known as thereference orbit. The mission consists of an only phase (phase A),using a 35 day repeat cycle, from 21 April 1995 to the present.ERS-2 is almost identical to the European Remote Sensing SatelliteERS-1 launched in 1991.  ERS-2 is capable of measuring, on a globalscale, the Earth&apos;s atmospheric and surface properties with a highdegree of accuracy. In fact it uses advanced microwave techniques tocollect global measurements and images (much of the data are collectedfrom remote areas such as the southern oceans and the Antarctic)independent of time of day and weather conditions. It also undertakesthe measurements of many parameters not covered by existing satellitesystems, including those of sea state, sea surface winds, oceancirculation and sea and ice levels.ERS-2 carries on-board a number of instruments consisting of a coreset of active microwave sensors supported by additional, complementaryinstruments: the Active Microwave Instrument (AMI), which combines aSynthetic Aperture Radar (SAR) operating in image or wave mode and awind scatterometer, the Radar Altimeter (RA), the Along-Track ScanningRadiometer and Microwave Sounder (ATSR-2), the Precise Range andRange-rate Equipment (PRARE), the Global Ozone Monitoring Experiment(GOME), and Laser Retroreflectors (LRR).The primary objectives of the ERS-2 mission are the monitoring of theoceans and sea ice providing essential data for:- improved representation of oceans/atmosphere interactionsin climatic models- major advances in the knowledge of ocean circulation andtransfer of energy- more reliable estimates of the mass balance of the Arcticand Antarctic ice sheets- better monitoring of pollution and dynamic coastalprocesses- improved detection and management of land use change.The capability of ERS-2 to acquire vast global data sets of ocean,atmosphere, ice and land phenomena contributes to the following typesof study and application:- Ocean/Ice: ocean circulation, global wind/waverelationships, sea ice and iceberg monitoring, etc.- Physical Earth: accurate determination of the oceangeoid, forestry, glaciology, geology and agriculturestudies, etc.- Climate: contribution to the World Climate ResearchProgramme and to the World Ocean Circulation Experiment- Weather and Sea: short and medium-term weatherforecasting, sea surface State Forecasting wind speed anddirection, location of pelagic fish through the monitoringof temperature fronts- Global Ozone: measures ozone, trace gases, and aerosolsin the troposphere and stratosphereGroup: Platform_Details   Entry_ID: ERS-2   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: ERS Earth Resource Satellite      Short_Name: ERS-2      Long_Name: European Remote Sensing Satellite-2   End_Group   Group: Synonymous_Platform_Names      Short_Name: ERS-2   End_Group   Group: Platform_Associated_Instruments      Short_Name: LRR      Short_Name: GOME      Short_Name: PRARE      Short_Name: ATSR-2      Short_Name: RA      Short_Name: SAR      Short_Name: AMI   End_Group   Group: Orbit      Orbit_Altitude: 785 km      Orbit_Inclination: 98.5 deg      Repeat_Cycle: 35 day   End_Group   Creation_Date: 2007-09-19   Online_Resource: http://earth.esa.int/ers/   Online_Resource: http://www.astronautix.com/craft/ers12.htm   Sample_Image: http://southport.jpl.nasa.gov/polar/satgifs/ers1.gif   Group: Platform_Logistics      Launch_Date: 1995-04-21      Launch_Site: Kourou, French Guiana      Primary_Sponsor: ESA   End_GroupEnd_Group</skos:definition>

text: The third flight in a series of Space Shuttle-Spacelab missions, designated the Atmospheric Laboratory for Applications and Science (ATLAS), was part of NASA&apos;s Mission to Planet Earth. The series was intended to study the composition of the middle atmosphere and its possible variations due to solar changes over the course of an 11-year solar cycle. The third flight of ATLAS focused on atmospheric and solar physics and consisted of the same experments as in ATLAS-2 with the addition of two co-manifested experiments. The ATLAS-3 instruments were mounted on Spacelab pallets in the Shuttle payload bay. The Shuttle&apos;s changing orientation to Earth placed the experiments in advantageous orbiting locations to observe the atmosphere and the Sun. The Shuttle orbiter orientation was either inertially fixed so that the selected instruments were pointed at the Sun, or nadir pointed for observations of the Earth&apos;s atmosphere. Crew members were in consultation with the investigators while controlling and monitoring the experiments. The ATLAS-3 core instruments consisted of: (1) Active Cavity Radiometer Irradiance Monitor (ACRIM); (2) Measurement of the Solar Constant (SOLCON); (3) Solar Spectrum Measurement (SOLSPEC); (4) Solar Ultraviolet Spectral Irradiance Monitor (SUSIM); (5) Atmospheric Trace Molecule Spectroscopy (ATMOS); and (6) Millimeter-Wave Atmospheric Sounder (MAS). The ATLAS-3 payload was co-manifested with the 6th flight of the Shuttle Solar Backscatter Ultraviolet (SSBUV-06) experiment, the German Space Agency (DARA) Shuttle Pallet Satellite/Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (SPAS/CRISTA) from Germany, and the Middle Atmospheric High Resolution Spectrograph Investigation (MAHRSI) from the Naval Research Laboratory (NRL). Both MAHRSI and CRISTA were mounted on the German SPAS carrier and were integrated into the ATLAS-3 science plan.

    <skos:definition xml:lang="en">The Orbiting Geophysical Observatory 4 (OGO 4) was a large observatoryinstrumented with experiments designed to study the interrelationships betweenthe aurora and airglow emissions, energetic particle activity, geomagneticfield variation, ionospheric ionization and recombination, and atmosphericheating which take place during a period of increased solar activity. After thespacecraft achieved orbit and the experiments were deployed into an operatingmode, an attitude control problem occurred.  This condition was corrected byground control procedures until complete failure of the tape recording systemsin mid-January 1969.  At that time, due to the difficulty of maintainingattitude control without the tape recorders, the attitude control system wascommanded off, and the spacecraft was placed into a spin-stabilized mode aboutthe axis which was previously maintained vertically.  In this mode, seven ofthe remaining experiments were turned off since no meaningful data could beobserved by them.  On October 23, 1969, the satellite was turned off. It wasreactivated again in January 1970 for 2 months to obtain VLF observations.

    <skos:definition xml:lang="en">The Orbiting Geophysical Observatory 3 (OGO 3) was launched on 7 June 1966 andput into orbit of 295 x 122,219 km at 31 degrees inclination. All 21experiments returned good data. At the time, this was the largest experimentalcomplement ever put into orbit. There were 4 cosmic ray instruments (1 of whichincluded a gamma-ray spectrometer), 4 plasma, 2 trapped radiation, 2 magneticfields, 5 ionosphere, 3 radio/optical, and 1 micrometeoroid detectors. Again,the GSFC positron search and gamma-ray spectrometer was included. Theexperiment was essentially identical to what was flown on OGO 1, with the PMTsbeing replaced by an improved variety. This time, the experiment was successfulin achieving all of its objectives. OGO 3 maintained 3-axis stabilization for46 days. At that point, an attitude controller failed and the spacecraft wasput into a spin on 23 July 1966. The spin period varied from 90-125 seconds. ByJune 1969, data acquisition was limited to 50% of the orbital path. Routineoperation was discontinued on 1 December 1969, and complete terminationoccurred on 29 February 1972.[Summary provided by NASA.]Group: Platform_Details   Entry_ID: OGO-3   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: OGO (Orbiting Geophysical Observatory)      Short_Name: OGO-3      Long_Name: Orbiting Geophysical Observatory-3   End_Group   Group: Synonymous_Platform_Names      Short_Name: EOGO 3      Short_Name: OGO-B      Short_Name: 02195   End_Group   Group: Platform_Associated_Instruments      Short_Name: GAMMA RAY SPECTROMETERS   End_Group   Group: Orbit      Orbit_Inclination: 31 degrees      Period: 2913.0 minutes      Perigee: 295.0 km      Apogee: 122219.0 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-02-13   Online_Resource: http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1966-049A   Sample_Image: http://heasarc.gsfc.nasa.gov/Images/ogo/ogo.gif   Group: Platform_Logistics      Launch_Date: 1966-06-07      Launch_Site: Cape Canaveral/Kennedy Space Center, USA      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">Challenger, the second orbiter to become operational at Kennedy  Space Center, was named after the British Naval research vessel  HMS Challenger that sailed the Atlantic and Pacific oceans  during the 1870&apos;s. The Apollo 17 lunar module also carried the  name of Challenger. Like her historic predecessors, Space  Shuttle Challenger and her crews made significant contributions  to America&apos;s scientific growth.Challenger started out as a high-fidelity structural test  article (STA-099). The airframe was completed by Rockwell and  delivered to Lockheed Plant 42 for structural testing on  02/04/78. The orbiter structure had evolved under such  weight-saving pressure that virtually all components of the air  frame were required to handle significant structural  stress. With such an optimized design, it was difficult to  accurately predict mechanical and thermal loading with the  computer software available at the time. The only safe approach  was to submit the structural test article to intensive testing  and analysis. STA-099 underwent 11 months of intensive  vibration testing in a 43 ton steel rig built especially for  the Space Shuttle Test Program. The rig consisted of 256  hydraulic jacks, distributed over 836 load application  points. Under computer control, it was possible to simulate the  expected stress levels of launch, ascent, on-orbit, reentry and  landing. Three 1 million pound-force hyd raulic cylinders were  used to simulate the thrust from the Space Shuttle Main  Engines. Heating and thermal simulations were also done.  On  January 28, 1986, the Challenger and its seven-member crew were  lost 73 seconds after launch when a booster failure resulted in  the breakup of the vehicle.[Summary provided by NASA]Group: Platform_Details   Entry_ID: OV-099   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: OV-099      Long_Name: Challenger Space Shuttle   End_Group   Group: Synonymous_Platform_Names      Short_Name: challenger   End_Group   Creation_Date: 2008-01-24   Online_Resource: http://www-pao.ksc.nasa.gov/kscpao/shuttle/resources/orbiters/challenger.html   Group: Platform_Logistics      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

Old Value=The Spacelab 3 mission was the second flight of Spacelab, the
reusable and versatile space laboratory developed for NASA by
the European Space Agency (ESA); it was also the first
NASA-dedicated Spacelab mission. The SL-3 crew consisted of
Commander Robert F. Overmyer, Pilot Frederick D. Gregory,
Mission Specialists Don L. Lind, Norman E. Thagard, and William
E. Thornton, and Payload Specialists Lodewijk van den Berg and
Taylor G. Wang. Rather than carrying experiments covering a
broad range of disciplines as did Spacelab 1, the SL-3 payload
investigations focused mainly on microgravity and included
experiments in life sciences, materials science, fluid
mechanics, and atmospheric and astronomical observations.

Old Value=Landsat 1, 2 and 3 operated in a circular, Sun-synchronous, near-polar orbit at
an altitude of approximately 913 km (567 miles), with a nominal 9:30 a.m.
crossing of the Equator during the descending mode.  They circled the Earth
every 103 minutes, completing 14 orbits per day and viewing the entire Earth
every 18 days.  The Landsat orbits are selected and trimmed so that each
satellite ground trace repeats its Earth coverage at the same local time every
day.  Repetitive image centers are maintained to within 37 km (23 miles). The
orbits of Landsat 4 and 5 are repetitive, circular, Sun-synchronous, and
near-polar at a nominal altitude of 705 km (438 miles) at the Equator. The
satellites cross the Equator from north-to-south on a descending orbital node
at approximately 9:45 a.m. on each pass.  Each orbit takes nearly 99 minutes,
and the spacecrafts complete just over 14 orbits each per day, covering the
entire Earth (poles excepted) every 16 days.  During processing, data obtained
is framed into individual scenes of the Earth&apos;s surface.  The ground
instantaneous field of view (IFOV) of the Landsat 1-3 MSS is 79m x 79m pixel
(resolution elements); the Landsat 4 and 5 MSS IFOV is 82m x 82m pixel. MSS
line scanning devices continually scan the Earth in a nominal 185 km swath
perpendicular to the Landsat orbital track.  The coverage patterns result in
14-percent image sidelap at the Equator for Landsat 1-3 data; Landsat 4 and 5
image side lap at the Equator is 7.3-percent. Image sidelap percentages
increase proportionally as the latitude increases.

Old Value=Landsat 2 is the second satellite of the Landsat program. The spacecraft
originally carried a designation of ERTS-B (Earth Resource Technology Satellite
B) but was renamed &amp;Landsat 2&amp; prior to its launch on January 22, 1975. Despite
having a design life of one year, Landsat 2 operated for over seven years,
finally ceasing operations on February 25, 1982.

As in the case of its predecessor Landsat 1, the satellite&apos;s payload included
two remote sensing instruments, the Return Beam Vidicon (RBV) and the
Multi-Spectral Scanner (MSS). The specifications for these instruments were
identical to those of the instruments carried on Landsat 1. (This was not the
case for Landsat 3, which added a short-lived thermal band to the MSS
instrument.) The data acquired by the MSS was considered more scientifically
useful than the data returned from the RBV, which was rarely used and
considered only for engineering evaluation purposes.

    <skos:definition xml:lang="en">During the 10 day mission, the Space Radar Laboratory (SRL) payload in Endeavour&apos;s cargo bay will make its second flight. The SRL payload, which first flew during STS-59 in April 1994, will again give scientists highly detailed information that will help them distinguish between human-induced environmental changes and other natural forms of change.SRL-2 will take radar images of the Earth&apos;s surface for Earth system sciences studies, including geology, geography, hydrology, oceanography, agronomy and botany.The SRL payload is comprised of the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR), and the Measurement of Air Pollution from Satellite (MAPS). The German Space Agency (DARA) and the Italian Space Agency (ASI) are providing the X-SAR instrument.The imaging radar of the SIR-C/X-SAR instruments has the ability to make measurements over virtually any region at any time, regardless of weather or sunlight conditions. The radar waves can penetrate clouds, and under certain conditions, also can &apos;see&apos; through vegetation, ice and extremely dry sand. In many cases, radar is the only way scientists can explore inaccessible regions of the Earth&apos;s surface. The SIR-C/X-SAR radar data provide information about how many of Earth&apos;s complex systems - those processes that control the movement of land, water, air and life - work together to make this a livable planet. The science team particularly wants to study the amount of vegetation coverage, the extent of snow packs, wetlands areas, geologic features such as rock types and their distribution, volcanic activity, ocean wave heights and wind speed. STS-68 will fly over the same sites that STS-59 observed so that scientists will be able to study seasonal changes that may have occurred in those areas between the missions.An international team of 49 science investigators and three associates will conduct the SIR-C/X-SAR experiments. Thirteen nations are represented: Australia, Austria, Brazil, Canada, China, the United Kingdom, France, Germany, Italy, Japan, Mexico, Saudi Arabia and the United States.The MAPS experiment will measure the global distribution of carbon monoxide in the troposphere, or lower atmosphere. Measurements of carbon monoxide, an important element in several chemical cycles, provide scientists with indications of how well the atmosphere can cleanse itself of &apos;greenhouse gases,&apos; chemicals that can increase the atmosphere&apos;s temperature.STS-68 provided a continuation of NASA&apos;s Get Away Special (GAS) experiments program. The project gives a person or organization a chance to perform experiments in space on a Shuttle mission. Two universities, North Carolina A&amp;T State University and University of Alabama in Huntsville, and the Swedish Space Corp., Soina, Sweden, will have small self-contained payloads flying during the STS-68 mission. Other GAS hardware in Endeavour&apos;s payload bay will carry 500,000 commemorative stamps for the U.S. Postal Service in recognition of the 25th anniversary of the Apollo 11 Moon landing.Other payloads aboard Endeavour include the Biological Research in Canister (BRIC) which will fly for the first time, and the Military Applications of Ship Tracks (MAST) which will be making its second flight. BRIC experiments, sponsored by NASA&apos;s Office of Life and Microgravity Sciences and Applications, are designed to examine the effects of microgravity on a wide range of physiological processes in higher order plants and arthropod animals (e.g., insects, spiders, centipedes, crustaceans). MAST is an experiment sponsored by the Office of Naval Research (ONR) and is part of a five-year research program developed by ONR to examine the effects of ships on the marine environment.The Commercial Protein Crystal Growth (CPCG) experiment, the Chromosome and Plant Cell Division in Space Experiment (CHROMEX) and the Cosmic Radiation Effects and Activation Monitor (CREAM) experiment also will be carried aboard Endeavour.[Summary provided by NASA]Group: Platform_Details   Entry_ID: SRL-2   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: SRL-2      Long_Name: Space Radar Laboratory-2   End_Group   Group: Synonymous_Platform_Names      Short_Name: SRL-2   End_Group   Group: Platform_Associated_Instruments      Short_Name: X-SAR   End_Group   Creation_Date: 2008-01-28   Online_Resource: http://www-pao.ksc.nasa.gov/shuttle/missions/backup%2010-5/sts-68/   Group: Platform_Logistics      Launch_Date: 1994-09-30      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

Old Value=OCO-2 is designed to provide space-based global measurements of atmospheric carbon dioxide (CO2) with the precision and resolution needed to identify and characterize the processes that regulate this important greenhouse gas. With its three high-resolution grating spectrometers, data collected by OCO-2 could be combined with meteorological observations and ground-based CO2 measurement to help characterize CO2 sources and sinks on regional scales at monthly intervals for 2 years.

New Value=The OCO-2 Project science objectives are to collect the space-based measurements needed to quantify variations in the column averaged atmospheric carbon dioxide (CO2) dry air mole fraction, XCO2, with the precision, resolution, and coverage needed to improve our understanding of surface CO2 sources and sinks (fluxes) on regional scales (≥1000km) and the processes controlling their variability over the seasonal cycle. This mission validates a space-based measurement approach and analysis concept that could be used for future systematic CO2 monitoring missions.

    <skos:definition xml:lang="en">The IRS-P3 satellite was launched from Sriharikota, India, using Polar Satellite Launch Vehicle – PLSV-D3. IRS-P3 was put in a polar, sun-synchronous orbit at an altitude of 817km with equatorial crossing time of 10:30 A.M in the descending node.IRS - P3 has an X-ray astronomy and two remote sensing payloads, namely Wide Field Sensor (WiFS) and Modular Optoelectronics Scanner (MOS). The mission caters to oceanography applications.IRS - P3 WiFS is similar to IRS - 1C WiFS but for the inclusion of an additional band in the Middle Infra-red (MIR) region. This sensor is primarily meant for vegetation dynamic studies while MOS is meant for ocean related studies. MOS has helped the ocean application scientists in developing necessary algorithms for extracting ocean parameters such as phytoplankton, yellow substance and suspended sediments in ocean waters.

    <skos:definition xml:lang="en">The Orbiting Geophysical Observatory (OGO 1) was successfully launched fromCape Kennedy on 5 September 1964 and placed into an initial orbit of 281 x149,385 km at 31 degrees inclination. Two experiment booms failed to properlydeploy, with one of the booms obscuring a horizon scanner&apos;s view of earth. As aresult, the spacecraft attitude could not be earth oriented and OGO 1 remainedspin stabilized at 5 rpm. Nevertheless, data from all 20 experiments on boardwas received, although at a &apos;less than expected capacity&apos; from some of them.During September 1964, acceptable data were received over 70% of the orbitalpath. Spacecraft operation was restricted to Spring and Fall due to powersupply limitations. There were 11 such 3-month periods prior to the spacecraftbeing put into stand-by mode on 25 November 1969. OGO 1 was completelyterminated on 1 November 1971.On board was the Positron Search and Gamma-Ray Spectrum experiment of Cline etal. It was designed to determine whether low-energy (0-3 MeV) positrons aretrapped temporarily or permanently in the Van Allen regions and whetherlow-energy solar and interplanetary positrons exist at the edge of the Earth&apos;smagnetic field. A secondary objective was to detect gamma-ray bursts from theSun in the energy range 80 keV - 1 MeV. The experiment consisted of 3 CsIcrystals surrounded by a plastic anti-coincidence shield. The output of thewhole unit was monitored by 3 PMTs. Once every 18.5 seconds, integral intensitymeasurements were made in each of 16 energy channels which were equally spacedover the .08-1 MeV range.The experiment did not achieve its goals due to electrical interference andsecular degradation of the PMT responses. However, searching back through thedata after the discovery of cosmic gamma-ray bursts by the Vela satellitesrevealed the detection of one or more such events in the OGO 1 data.[Summary provided by NASA.]Group: Platform_Details   Entry_ID: OGO-1   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: OGO (Orbiting Geophysical Observatory)      Short_Name: OGO-1      Long_Name: Orbiting Geophysical Observatory-1   End_Group   Group: Synonymous_Platform_Names      Short_Name: EOGO 1      Short_Name: OGO-A      Short_Name: 00879   End_Group   Group: Platform_Associated_Instruments      Short_Name: SPECTROMETERS      Short_Name: MAGNETOMETERS   End_Group   Group: Orbit      Orbit_Inclination: 31.2 degrees      Period: 3839.0 minutes      Perigee: 281.0 km      Apogee: 149385.0 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-02-12   Online_Resource: http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1964-054A   Online_Resource: http://heasarc.gsfc.nasa.gov/docs/heasarc/missions/ogo.html#ogo1   Sample_Image: http://heasarc.gsfc.nasa.gov/Images/ogo/ogo.gif   Group: Platform_Logistics      Launch_Date: 1964-09-05      Launch_Site: Cape Canaveral/Kennedy Space Center, USA      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">Atlantis, the fourth orbiter to become operational at Kennedy  Space Center, was named after the primary research vessel for  the Woods Hole Oceanographic Institute in Massachusetts from  1930 to 1966. The spaceship Atlantis has carried on the spirit  of the sailing vessel with several important voyages of its own,  including the Galileo planetary explorer mission in 1989 and the  deployment of the Arthur Holley Compton Gamma Ray Observatory in  1991.Atlantis benefited from lessons learned in the construction and  testing of Enterprise, Columbia and Challenger. At rollout, its  weight was some 6,974 pounds less than Columbia. The Experience  gained during the Orbiter assembly process also enabled  Atlantis to be completed with a 49.5 percent reduction in man  hours (compared to Columbia). Much of this decrease can be  attributed to the greater use of thermal protection blankets on  the upper orbiter body instead of tiles. During the  construction of Discovery and Atlantis, NASA opted to have the  various contractors manufacture a set of &apos;structural spares&apos; to  facilitate the repair of an Orbiter if one was damaged during  an accident. This contract was valued at &amp;#36389 million  and consisted of a spare aft-fuselage, mid-fuselage, forward  fuselage halves, vertical tail and rudder, wings, elevons and a  body flap. These spares were later assembled into the orbiter  Endeavour. Atlantis was shipped to California to undergo  upgrades and modifications. These modifications include a drag  chute, new plumbing lines that configure the orbiter for  extended duration, more than 800 new heat protection tiles and  blankets and new insulation for the main landing gear.[Summary provided by NASA]Group: Platform_Details   Entry_ID: OV-104   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: SPACE SHUTTLE      Short_Name: OV-104      Long_Name: Atlantis Space Shuttle   End_Group   Group: Synonymous_Platform_Names      Short_Name: Atlantis   End_Group   Creation_Date: 2008-01-25   Online_Resource: http://science.ksc.nasa.gov/shuttle/resources/orbiters/atlantis.html   Sample_Image: http://www.centralfloridavillaholiday.com/images/nasa_shuttle_launch.jpg   Group: Platform_Logistics      Launch_Date: 1985-10-03      Launch_Site: Cape Canaveral/Kennedy Space Center, USA      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The Indian Remote Sensing Satellite-1A (IRS-1A) was launched on March 17, 1988.  IRS-1A is the first of a series of semi-operational/ operational remote sensing satellites developed by Indian Space Research Organisation (ISRO) for land-based applications such as agriculture,forestry, geology, and hydrology.  The three-axis-stabilized sun-synchronous satellite carries two linear imaging self-scanned sensors (LISS). LISS-1 and LISS-II perform &apos;pushbroom&apos; scanning in visible and near IR bands to acquire images of the earth.  Both push-broom scanning sensors operate in the four spectral bands: 0.45-0.52, 0.52-0.59, 0.62-0.68, and 0.77-0.86 micrometer.  Local equatorial crossing time is fixed at around 10 a.m.  The spacecraft platform, measuring 1.56 m x 1.66 m x 1.10 m, has the payload module attached on the top and a deployable solar array stowed on either side.  Attitude control is provided by four momentum wheels, two magnetic torques, and a thruster system. Together these mechanisms provide an estimated accuracy of plus or minus 0.10 deg in all three axes.Group: Platform_Details   Entry_ID: IRS-1A   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: IRS (Indian Remote Sensing Satellite)      Short_Name: IRS-1A      Long_Name: Indian Remote Sensing Satellite-1A   End_Group   Group: Synonymous_Platform_Names      Short_Name: IRS-1A   End_Group   Group: Platform_Associated_Instruments      Short_Name: LISS-II      Short_Name: LISS-I   End_Group   Group: Orbit      Orbit_Altitude: 904 km      Orbit_Inclination: 99.01 deg      Period: 103.1minutes      Repeat_Cycle: 22 days      Perigee: 863 km      Apogee: 917 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-10-05   Online_Resource: http://www.isro.gov.in/satellites/irs-1a.aspx   Sample_Image: http://www.isro.gov.in/satellites/images/irs1a_img.gif   Group: Platform_Logistics      Launch_Date: 1988-03-17      Launch_Site: BAIKONUR COSMODROME, TYURATAM, RUSSIA      Primary_Sponsor: India   End_GroupEnd_Group</skos:definition>

text: The ESSA-4 satellite replaced ESSA-2 and provided direct readout cloud-cover photography to ground stations worldwide using APT. The spacecraft was an 18-sided polygon, 42 inches in diameter, 22 inches high and weighed 290 pounds; it was made of aluminum alloy and stainless steel, then covered with 9100 solar cells. The solar cells served to charge the 63 nickel-cadmium batteries.

The two cameras were mounted 180-degrees opposite each other along the side of the cylindrical craft. The &quot;cartwheel&quot; configuration of the TIROS-9 was selected as the orbital configuration of the ESSA satellites. Therefore, a camera could be pointed at some point on Earth every time the satellite rotated along its axis. The spacecraft operating system was the same as on the TIROS-9. The craft was placed in its planned Sun-synchronous 101-degree inclination retrograde orbit. The APT system was designed to transmit an image every 352 seconds, each photo covering a 2000-square mile area with 2-mile resolution. ESSA-4 was able to transmit two to three images daily to individual ground stations regardless of their location.

Launch Date: January 26, 1967
Operational Period:  465 days until deactivated by NASA on May 5, 1968

Old Value=The MIPS2 is a mobile profiling system with several components
and capabilities.

1. Radian: (915 MHz 5-beam Doppler profiling radar) collects
Doppler spectra, calculates the spectrum moments, determines
wind profiles at 1-60 min intervals, acquires,
vertically-pointing data at 40-60 times resolution and 60, 105,
or 210 m vertical resolution.

2. Radian: (2 kHz Doppler sodar) determines wind profiles w and
backscatter power at 20 s time resolution and 25 m vertical
resolution.

3. Radio Acoustic Sounding System (RASS): using the sodar as the
acoustic source, the profile of T can be determined fro ~120 m
to 0.5-1.5 km AGL, dependent on water vapor content, wind speed
and turbulence.

4. Vailalla: (0.906 um lidar ceilometer) determines cloud base
and provides a good estimate of the lidar backscatter (or
extinction coefficient) from aerosols, clouds, and
precipitation.

5. Radiometrics: (12 channel microwave radiometer) measures
profiles of T, water vapor, cloud water, and column integrated
values of water vapor and cloud water, at 10 min intervals up to
10 km, with highest vertical resolution oat low levels. This
system also includes an infrared pyranometer, which measures
cloud base temperature.

6. Zenith cloud imaging system: This will consist of an upward
directed computer controlled, digital camera system that will
provide visible images of the sky at user-selected levels.

7. Surface Instrumentation: T, relative humidity, wind,
pressure, solar radiation, and rainfall rate, all at 1-s
resolution, An improved aspiration system designed for rainy
high wind conditions has been designed for accurate measurements
of T and RH.

text: Launched in October 2006, the Solar Terrestrial Relations Observatory, or STEREO, has provided scientists a unique and revolutionary view of the Sun-Earth System. Composed of two nearly identical observatories -- one ahead of Earth in its orbit, the other trailing behind --  STEREO has traced the flow of energy and matter from the Sun to Earth. 

 
Solar ejections, like coronal mass ejections (CMEs), are the most powerful drivers of the Sun-Earth connection. Yet despite their importance, scientists don&apos;t fully understand the origin and evolution of CMEs, nor their structure or extent in interplanetary space. STEREO&apos;s unique 3D images of the structure of CMEs is enabling scientists to determine their fundamental nature and origin.

STEREO is also a key addition to the fleet of space weather detection satellites. It provides more accurate alerts for the arrival time of Earth-directed solar ejections with its unique side-viewing perspective.

 
On Oct. 1, 2014, NASA mission operations lost communication with one of the spacecraft, STEREO-B. Efforts to regain contact are ongoing. STEREO-A continues to operate normally and provide views of parts of the far side of the Sun otherwise unseeable from Earth’s perspective.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).
Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

New Value=The second mobile platform deployed for LMOS 2017 was the UW-Eau Claire automobile1367 platform, equipped with a 2-B Technologies Personal Ozone Monitor and a handheld Kestrel weather sensor. This platform made regular measurement stops between the Grafton WDNR site and the Sheboygan Spaceport site to investigate N-S and shallow E-W gradients. The ozone measurements were taken at a height of 3 m for at least 5 minute increments at each location. The 15 stops are described in 1371 Table 2.6.2. On June 2, 3, 12, 13, and 17 the UW-Eau Claire vehicle drove the route of some combination
of the stops (e.g. Stops 1-13 on June 2, Stops 10-15 multiple times on June 3 to correspond to ship and aircraft measurements made concurrently). Data from the ozone monitor was obtained using 1 minute averaged signal. The duty cycle of the Personal Ozone Monitor subtracts a background (scrubbed ozone)
UV-signal from a whole air sample, which accounts for the UV absorption of water. However, drastically changing humidity can lead to higher standard deviations in this instrument, which is why the vehicle chose to stop at a single location to measure ozone.</skos:changeNote>

    <skos:definition xml:lang="en">Alouette-1 was a small ionospheric space based observatory instrumentedwith an ionospheric sounder (radio transmitter), a VLF radio wave receiver,an energetic particle detector, and a cosmic radio noise experiment.EXTERIOR EQUIPMENT:  Extended from the satellite skin (shell) were twodipole antennas (45.7-meter and 22.8-meter long, respectively) which wereshared by three of the experiments on this spacecraft.SPACECRAFT ROTATION (SPIN):  The satellite was spin-stabilized atabout 1.4 rpm after antenna extension.  After about 500 days in orbit,the ALOUETTE-1 spin rate slowed more than had been expected, to about0.6 rpm when satellite spin-stabilization failed.  It is now believedthat the satellite gradually progressed towards a gravity gradientstabilization with the longer antenna pointing earthward.  Attitudeinformation was deduced from a single onboard magnetometer only, andaided by temperature measurements on the upper and lower heat shields.DATA ACQUISITION:  Alouette-1 was an early space era satellite, andthere was no onboard tape recorder so data were available to theground stations only from the immediate vicinity of the telemetrystations.  The ground telemetry stations were located to provideprimary data coverage near the 80 degrees West meridian and inareas near Hawaii, Singapore, Australia, Europe and Central Africa.Initially, data were recorded for about 6 hours per day.  In September1972, spacecraft operations were terminated.Group: Platform_Details   Entry_ID: ALOUETTE-1   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: ALOUETTE      Short_Name: ALOUETTE-1   End_Group   Group: Synonymous_Platform_Names      Short_Name: ALOUETTE-A      Short_Name: 00424   End_Group   Group: Platform_Associated_Instruments      Short_Name: TELEMETER      Short_Name: MAGNETOMETERS      Short_Name: PARTICLE DETECTORS   End_Group   Creation_Date: 2007-08-22   Online_Resource: http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1962-049A   Group: Platform_Logistics      Launch_Date: 1962-09-29       Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The aim of the Cluster mission is to study small-scale structures of themagnetosphere and its environment in three dimensions. To achieve this, Clusteris constituted of four identical spacecraft that will flight in a tetrahedralconfiguration. The separation distances between the spacecraft will be variedbetween 600 km and 20 000 km, according to the key scientific regions. The first Cluster mission was launched on 4 June 1996, but the launch vehicle exploded 37 seconds into the flight.Cluster II was launched from Baikonur Cosmodrome in Kazakhstan on 16 July 2000and 9 August 2000. The four satellites were put into orbit, in pairs, by twoSoyuz rockets provided by the Russian-French Starsem company. Starsem has fourshareholders - Aerospatiale, Arianespace, the Russian Space Agency and TsSKBSamara, the manufacturer of the Soyuz vehicle. Each of the four spacecraft carries an identical set of 11 instruments toinvestigate charged particles, electrical and magnetic fields.

The satellite wasEarth oriented, three-axis stabilized and weighed approximately2200 pounds.  NOAA-13 was the sixth operational satellite in theAdvanced TIROS-N series. The satellite carried the AVHRR, TOVS,and the solar proton monitor. All of which were present onprevious NOAA satellites. The ERBE instruments, the SBUVradiometer and the SARSAT systems were also flown on thissatellite.NOAA-13 was placed in a near circular, (470nm) polar orbit. Thespacecraft and its systems operated successfully for 12 daysuntil a circuit failure resulted in a power loss aboard thecraft. At this time the spacecraft is still in its polar orbit;however, no data is being received.Specifications:Prime contractor: GE AstroPlatform: evolved from NOAA 2nd generationMass at launch: 1420 kgMass in orbit: ~1050 kgDimension: 4.18 m long x 1.88 m diameterStabilization: 3-axisDesign lifetime:  3 yearsAPT downlink freq: 137.620 MHz (standby)HRPT downlink freq: 1698.0 MHzBeacon: 136.770 MHzPayload:AVHRR (Advanced Very High Resolution Radiometer:Wavebands:0.58-0.68 µm (visible): cloud, snow and ice monitoring0.725-1.10 µm (near IR): water, vegetation and agriculture surveys3.55-3.93 µm (near IR): sea surface temperature, volcano, forestfire activity 10.3-11.3 µm (thermal IR): sea surfacetemperature, soil moisture 11.3-12.5 µm (thermal IR): seasurface temperature, soil moisture Resolution: 1.1 km Swathwidth: 3000 kmTOVS (Tiros Operational Vertical Sounder):HIRS/2 (High Resolution IR Sounder): 20 channels in the 0.69 -14 - 95 µm band; 17.4 km resolutionSSU (Stratospheric Sounding Unit): step-scanned far IRspectrometer with 3 channels in the CO² absorption band (15µm);147.3 km resolutionMSU (Microwave Sounding Unit): passive 4-channel radiometeroperating around 55 GHz; 109 km resolutionPARTICIPANTS:NASA, USAF, ITT, Martin Marietta AstroSpace, Ball Aerospace,Marconi, JPL, Loral, NOAA, National Weather Service.[Summary provided by NOAA and The Satellite Encyclopedia]Group: Platform_Details   Entry_ID: NOAA-13   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: NOAA POES (Polar Orbiting Environmental Satellites)      Short_Name: NOAA-13      Long_Name: National Oceanic &amp; Atmospheric Administration-13   End_Group   Group: Synonymous_Platform_Names      Short_Name: ATLES E   End_Group   Group: Platform_Associated_Instruments      Short_Name: TOVS      Short_Name: HIRS/2      Short_Name: MSU      Short_Name: SSU   End_Group   Group: Orbit      Period: 12 days   End_Group   Creation_Date: 2007-11-05   Online_Resource: http://www2.ncdc.noaa.gov/docs/podug/html/c1/sec1-49.htm   Sample_Image: http://www2.ncdc.noaa.gov/docs/podug/images/guide/f149-3.gif   Group: Platform_Logistics      Launch_Date: 1993-08-09      Launch_Site: Vandenberg Air Force Base, USA      Design_Life: 3-years      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

The Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) mission objective is to make global atmospheric 
column carbon dioxide (CO2) measurements without a seasonal, latitudinal, or diurnal bias. The three science objectives are 
to (1) quantify global spatial distributions of atmospheric CO2 on scales of weather models in the 2010-2020 era; (2) quantify
 the current global spatial distribution of terrestrial and oceanic sources and sinks of CO2 on 1-degree grids at weekly 
 resolution; and (3) provide a scientific basis for future projections of CO2 sources and sinks through data-driven 
 enhancements of Earth system process modeling.

Mission objectives:

    * Measure the number density of Carbon Dioxide (CO2) in the column of air beneath the aircraft
    * Measure length of the column using a laser altimeter
    * Measure ambient air pressure and temperature. 

ASCENDS will provide improved ability to predict/model long-term changes in the climate cycle based both on the understanding of the natural processes driving the variability of natural carbon sources and sinks, and on the transport of carbon through the atmosphere.

    <skos:definition xml:lang="en">Spacecraft Brief Description  Gemini  8 was the sixth manned earth-orbiting spacecraft of the Gemini  series.  The primary mission objectives were to perform rendezvous and  four  docking  tests  with  the Agena target vehicle and to execute an  extravehicular  activity (EVA) experiment. Ten technological, medical,  and   scientific  experiments  were  carried  on  board.  Of  the  six  scientific  experiments  only  the Agena micrometeorite collection was  successful. the others -- (1) zodiacal light photography, (2) frog egg  growth,  (3)  synoptic terrain photography, (4) nuclear emulsions, and  (5)  spectrophotography of clouds -- were incomplete, owing to a large  loss of fuel and early termination of the mission. The EVA docking and  other  maneuvers  were  canceled. The spacecraft reentered the earth&apos;s  atmosphere  after  6.5 orbits and landed in the pacific ocean on March  17, 1966.Auxiliary Information  Launch Date and Time : 1966-03-16 16:48:00  Epoch Date and Time :  1966-03-17  Orbit Type :  Geocentric  Apogee(km) :     298.

Old Value=The ALTUS II, the first of the two craft to be completed, made its first flight on May 1, 1996. With its engine at first augmented by a single-stage turbocharger, the ALTUS II reached an altitude of 37,000 ft during its first series of development flights at Dryden in August, 1996. In October of that year, the ALTUS II was flown in an Atmospheric Radiation Measurement (ARM-UAV) study in Oklahoma conducted by Sandia National Laboratories for the Department of Energy (DOE). During the course of those flights, the ALTUS II set a single-flight endurance record for remotely operated aircraft of more than 26 hours.

The ALTUS I, completed in 1997, flew a series of development flights at Dryden that summer. Those test flights saw the craft reach an altitude of 43,500 ft while carrying a simulated 300-lb payload, a record for a remotely operated aircraft powered by a piston engine augmented with a single-stage turbocharger.

After major modifications and upgrades, including installation of a two-stage turbocharger in place of its original single-stage unit, a larger fuel tank and additional intercooling capacity, the ALTUS II returned to flight status in the summer of 1998. The goal of its development test flights was to reach one of the major Level 2 performance milestones within NASA&apos;s ERAST program: to fly a gasoline-fueled, piston-engine remotely piloted aircraft for several hours at an altitude at or near 60,000 feet. On March 5, 1999, The ALTUS II maintained flight at or above 55,000 feet for three hours, reaching a maximum density altitude of 57,300 feet during the mission.

Later that spring, the ALTUS II flew another series of Atmospheric Radiation Measurement missions conducted by Sandia National Laboratories for the DOE. Hard-to-measure properties of high-level cirrus clouds that may affect global warming were recorded using specially designed instruments while the Altus flew at 50,000 feet altitude off the Hawaiian island of Kaua&apos;i. Clouds both reflect incoming solar energy back to space, and absorb warm longwave radiation from the Earth&apos;s surface, keeping that heat in the atmosphere. Data from the study will help scientists better understand how these dual roles of clouds in reflecting and absorbing solar energy work, and build more accurate global climate models.

In September, 2001, ALTUS II served as the UAV platform for a flight demonstration of remote sensoring and imaging capabilities that could detect hot spots in wildfires and relay that data in near- real time via the Internet to firefighting commanders below. The demonstration, led by NASA Ames Research Center, was flown over GA-ASI&apos;s El Mirage development facility in Southern California.

In the summer of 2002, The Altus II served as the airborne platform for the Altus Cumulus Electrification Study (ACES), led by Dr. Richard Blakeslee of NASA Marshall Space Flight Center. The ACES experiment focused on the collection of electrical, magnetic and optical measurements of thunderstorms. Data collected will help scientists understand the development and life cycles of thunderstorms, which in turn may allow meteorologists to more accurately predict when destructive storms may hit.

text: IRNSS is an independent regional navigation satellite system being developed by India. It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area. An Extended Service Area lies between primary service area and area enclosed by the rectangle from Latitude 30 deg South to 50 deg North, Longitude 30 deg East to 130 deg East.

IRNSS will provide two types of services, namely, Standard Positioning Service (SPS) which is provided to all the users and Restricted Service (RS), which is an encrypted service provided only to the authorised users. The IRNSS System is expected to provide a position accuracy of better than 20 m in the primary service area.

 (France), the second French experimental data relay satellite
 for meteorological data and the first launched by NASA under a
 cooperative agreement with the Centre National d&apos;Etudes
 Spatiales (CNES), was designed to function primarily as a
 communications satellite to acquire and relay telemetered data
 on altitude, pressure, temperature, moisture, and upper
 atmospheric wind velocities from instrumented earth-circling
 constant density meteorological balloons. The octagonally
 shaped satellite measured 0.71 m across opposite corners and
 was 0.58 m long. Electrical power (20 W average) was supplied
 by eight rectangular solar panels deployed 45 deg from the EOLE
 1 upper octagonal structure after orbital insertion, and by 15
 rechargeable silver-cadmium batteries. Constant earth
 orientation was maintained by a deployable 10.06-m gravity
 gradient boom. Satellite spin was near zero rpm in orbit, and
 the attitude was programme!  d to remain stable within 9 deg of
 local vertical. The data were stored on board the spacecraft
 and unloaded on command when the spacecraft was within range of
 the ground station. The onboard telemetry consisted of (1) a
 136.350-MHz downlink transmitter for relaying balloon telemetry
 to ground stations and also to serve as a tracking beacon, (2)
 a 148.25-MHz receiver for receiving spacecraft commands and
 telemetry programs for balloon operations, and (3) a
 spacecraft-to-balloon transmitter (464.84 MHz) and receiver
 (401.7196 MHz). The satellite operation was successful with the
 exception of the inadvertent destruction of 71 balloons by an
 erroneous ground command. The last balloon ceased transmitting
 in January 1973. However, the spacecraft was subsequently used
 to track and receive data from ocean buoys, icebergs, and
 ships.

text: The first proposal to use satellites for navigation was made by V.S.Shebashevich in 1957. This idea was born during the investigation of the possible application of radio-astronomy technologies for aeronavigation. Further investigations were conducted in a number of the Soviet institutions to increase the accuracy of navigation definitions, global support, daily application and independence from weather conditions. The research results were used in 1963 for R&amp;D project on the first Soviet low-orbit “Cicada” system. In 1967 the first navigation Soviet satellite &quot;Cosmos-192&quot; was launched. The navigation satellite provided continuous radio navigation signal transmission on 150 and 400 MHz during its active lifetime.

The “Cicada” system of four satellites was commissioned in 1979. The navigation satellites were placed into circular orbits 1,000 km high with an inclination of 83 ° and equal distribution of orbital planes to the equator. It allowed users to acquire one of the satellites every hour and a half or two and fix the position within 5-6 min of a navigation session. The navigation system “Cicada” used one-way user-to-satellite range measurements. Along with improvement of the satellite onboard systems and navigation equipment much attention was given to enhancing accuracy of determining and predicting parameters of the navigation satellite orbits.

Later, receiving measuring equipment was disposed on the “Cicada” satellites to detect distress radiobeacons. The satellites received these signals and rebroadcast them to special ground stations where the computation of the exact coordinates of the emergency objects (ships, aircraft, etc.) was held. The “Cicada” satellites tracking distress radiobecons formed “Cospas” system that together with the US-French-Canadian &quot;Sarsat&quot; system built an integrated search and rescue service that saved several thousands of lives. The “Cicada” space navigation system (and its “Cicada-M” modernization) was designed for navigation support of military users and had been in use since 1976. In 2008 “Cicada” and “Cicada-M” users started to use GLONASS system and the operation of those systems was halted. It was impossible for the low-orbit systems to meet requirements of a great number of users.

Successful operation of the low-orbit satellite navigation systems by the marine users attracted widespread attention to satellite navigation. A general-purpose navigation system was needed to meet the requirements of the great majority of prospective users.

Based on the all-round research it was decided to choose the orbital constellation consisting of 24 satellites equally distributed in three orbital planes inclined at 64.8° to the equator. The GLONASS satellites are placed in roughly circular orbits with the nominal orbit altitude 19,100 km and an orbital period of 11 hours, 15 minutes, 44 seconds. Due to the period value it became possible to create a sustainable orbital system that unlike GPS does not require supporting correcting pulses during its active lifetime. The nominal inclination ensures global availability on the territory of the Russian Federation even when several SVs are not operational.

Two challenges have been faced for designing a high-orbit navigation system. The first one dealt with mutual synchronized satellite timescales with the accuracy of billionths of a second (nanoseconds). It became possible because of high-orbit onboard caesium frequency standards with nominal stability at 10-13 and ground hydrogen frequency standard with nominal stability at 10-14 and also because of ground facilities of time scale comparison with error of 3-5 ns. The second challenge addressed high-precision determination and prediction of navigation satellite orbit parameters. This issue was solved with scientific research on second order factors of infinitesimals, such as light pressure, irregularities of the Earth rotation and polar motions and etc.

Flight tests of the Russian high orbit satellite navigation system, called GLONASS, were started in October, 1982 with the launch of “Kosmos-1413” satellite. The GLONASS system was formally declared operational in 1993. In 1995 it was brought to a fully operational constellation (24 GLONASS satellites of the first generation). A great drawback that should have been focused on consisted in the lack of civil navigation equipment and civil users.

Reduction in funding for space industry in 1990 led to degradation of the GLONASS constellation. In 2002 the GLONASS constellation consisted of 7 satellites that was insufficient for navigation support of the Russian territory even with limited availability. GLONASS was behind GPS in accuracy characteristics, SVs active lifetime comprised 3-4 years.

    <skos:definition xml:lang="en">The first proposal to use satellites for navigation was made by V.S.Shebashevich in 1957. This idea was born during the investigation of the possible application of radio-astronomy technologies for aeronavigation. Further investigations were conducted in a number of the Soviet institutions to increase the accuracy of navigation definitions, global support, daily application and independence from weather conditions. The research results were used in 1963 for R&amp;D project on the first Soviet low-orbit “Cicada” system. In 1967 the first navigation Soviet satellite &apos;Cosmos-192&apos; was launched. The navigation satellite provided continuous radio navigation signal transmission on 150 and 400 MHz during its active lifetime.The “Cicada” system of four satellites was commissioned in 1979. The navigation satellites were placed into circular orbits 1,000 km high with an inclination of 83 ° and equal distribution of orbital planes to the equator. It allowed users to acquire one of the satellites every hour and a half or two and fix the position within 5-6 min of a navigation session. The navigation system “Cicada” used one-way user-to-satellite range measurements. Along with improvement of the satellite onboard systems and navigation equipment much attention was given to enhancing accuracy of determining and predicting parameters of the navigation satellite orbits.Later, receiving measuring equipment was disposed on the “Cicada” satellites to detect distress radiobeacons. The satellites received these signals and rebroadcast them to special ground stations where the computation of the exact coordinates of the emergency objects (ships, aircraft, etc.) was held.

    <skos:definition xml:lang="en">The LAGEOS satellites are passive vehicles covered withretroreflectors designed to reflect laser beams transmitted fromground stations. By measuring the time between transmission ofthe beam and reception of the reflected signal from thesatellite, stations can precisely measure the distance betweenthemselves and the satellite. These distances can be used tocalculate station positions to within 1-3 cm. Long term datasets can be used to monitor the motion of the Earth&apos;s tectonicplates, measure the Earth&apos;s gravitational field, measure the&apos;wobble&apos; in the Earth&apos;s axis of rotation, and better determinethe length of an Earth day.LAGEOS 2 was a joint program between NASA and the Italian spaceagency (ASI), which built the satellite using LAGEOS 1 drawingsand specifications, handling fixtures, and other materialsprovided by NASA.LAGEOS 2&apos;s orbit was selected to provide more coverage of  seismically active areas, such as the Mediterranean Basin and  California, and may help scientists understand irregularities  noted in the motion of LAGEOS 1. Ground tracking stations are  located in many countries (including the US, Mexico, France,  Germany, Poland, Australia, Egypt, China, Peru, Italy, and  Japan) and data from these stations is available world-wide to  investigators studying crustal dynamics. LAGEOS 1 also  contains a message plaque addressed to human and other beings  of the far distant future with maps of the Earth from 3  different eras - 268 million years in the past, present day,  and 8 million years in the future (the satellite&apos;s estimated  decay date). Spacecraft: Both satellites are spherical bodies  with an aluminum shell wrapped around a brass core. The design  was a compromise between numerous factors including the need  to be as heavy as possible to minimise the effects of  non-gravitational forces vs.  being light enough to be placed  in a high orbit and the need to accommodate as many  retroreflectors as possible vs. the need to minimise surface  area to minimise the effects of solar pressure. The materials  were chosen to reduce the effects of the Earth&apos;s magnetic  field on the satellite&apos;s orbit.426 cube-corner retroreflectors  are imbedded in the satellites&apos; surface.422 of these are made  of fused silica glass while the other 4 are made of  germanium. The vehicles have no onboard sensors or  electronics, and are not attitude controlled. Payload: Science  is performed by reflecting laser light from the vehicle&apos;s 426  retroreflectors.

text: NOAA’s GOES-19 satellite, the latest and final satellite in NOAA’s GOES-R Series, officially began operations as GOES East on April 2025. This milestone comes after its June 25, 2024 launch, and subsequent post-launch testing of its instruments, systems and data.

GOES-19 replaces GOES-16 as GOES East, positioned 22,236 miles above the equator at 75.2 degrees west longitude. GOES-16 will now become a backup for NOAA’s operational geostationary constellation, maintaining its operational readiness for future use, if needed.

    <skos:definition xml:lang="en">GEMINI 4 was the second manned mission of the GEMINI series and carried J. A. Mcdivitt and E. H. White on a 4-day, 62-orbit, 98-hr flight from June 3 to June 7, 1965. The spacecraft was conical and had a diameter of 3.05 m at the large end, which was the rear of the spacecraft and which was covered by a fiberglass heat shield to protect the craft during reentry. The objective of the mission was to test the performance of the astronauts and capsule for an extended length of time in space. The spacecraft was transported to space with a titan rocket. White performed a 23-min eva (walk) in space attached to the spacecraft by an 8-m tether. Medical and engineering experiments were performed. The scientific experiments performed were visual and photographic. The experiments performed were electrostatic charge (msc-1), proton-electron spectrometer (msc-2), triaxial magnetometer (msc-3), two-color earth limb photos (msc-10), inflight exerciser (m-3), inflight phonocardiogram (m-4), bone demineralization (m-6), synoptic terrain photos (s-5), synoptic weather photos (s-6), dim and twilight phenomena (s-28), radiation (d-8), and simple navigation (d-9). The mission was successful, and the spacecraft landed in the pacific on June 7, 1965.Group: Platform_Details   Entry_ID: GEMINI-4   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: GEMINI      Short_Name: GEMINI-4   End_Group   Group: Synonymous_Platform_Names      Short_Name: Titan-II (4)   End_Group   Group: Orbit      Orbit_Inclination: 32.53 degrees      Period: 56 minutes      Repeat_Cycle: 4 days      Perigee: 162 km      Apogee: 281 km   End_Group   Creation_Date: 2008-01-23   Online_Resource: http://science.ksc.nasa.gov/history/gemini/gemini-iv/gemini-iv.html   Sample_Image: http://science.ksc.nasa.gov/history/gemini/gemini-iv/gemini-iv-patch-small.gif   Group: Platform_Logistics      Launch_Date: 1965-06-03      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">Spacecraft Brief Description  LAGEOS  (Laser Geodetic Satellite) was a very dense (high mass-to-area  ratio)  laser  retroreflector  satellite  which  provided  a permanent  reference   point   in   a   very  stable  orbit  for  such  precision  earth-dynamics  measurements  as  crustal  motions,  regional strains,  fault motions, polar motion and earth-rotation variations, solid earth  tides,  and  other  kinematic  and  dynamic parameters associated with  earthquake   assessment   and   alleviation.     In  conjunction  with  appropriate   laser-tracking   systems,   LAGEOS   permitted   extreme  precision-ranging     measurements    for    both    geometric    mode  (multilateration) and orbital dynamic mode determinations of positions  of  points  on  the  earth.   It  was  the  first spacecraft dedicated  exclusively  to  high-precision  laser  ranging and provided the first  opportunity  to  acquire  laser-ranging data that were not degraded by  errors  originating  in the target satellite.  The high-accuracy range  measurements from this permanent-orbiting reference point were used to  accomplish many extreme precision earth-dynamics measurements required  by  the earthquake hazard assessment and alleviation objectives of the  Earth and Ocean Physics Applications Program (EOPAP).  The performance  in   orbit   of   LAGEOS  was  limited  only  by  degradation  of  the  retroreflectors,  so many decades of useful life can be expected.  The  high mass-to-area ratio and the precise, stable (attitude-independent)  geometry  of  the  spacecraft,  together  with  the  orbit,  made this  satellite  the  most precise position reference available.  Because it  is  visible  in  all  parts of the world and has an extended operation  life in orbit, LAGEOS can serve as a fundamental standard for decades.Auxiliary Information  Launch Date and Time : 1976-05-04 08:00:00  Epoch Date and Time :  1976-05-05  Orbit Type :  Geocentric  Apogee(km) :    5946.

    <skos:definition xml:lang="en">Nimbus-2 was launched in May 1966 and was the second in a series ofsecond-generation meteorological research-and-development satellites that wasdesigned to serve as a stabilized, earth-oriented platform for the testing ofadvanced meteorological sensor systems and for collecting meteorological data.The polar-orbiting spacecraft consisted of three major elements: (1) a sensoryring, (2) solar paddles, and (3) the control system housing. The solar paddlesand the control system housing were connected to the sensory ring by a trussstructure, giving the satellite the appearance of an ocean buoy. Nimbus-2 wasnearly 3.7 m tall, 1.5 m in diameter at the base, and about 3 m across withsolar paddles extended. The sensory ring, which formed the satellite base,housed the electronics equipment and battery modules. The lower surface of thetorus-shaped sensory ring provided mounting space for sensors and telemetryantennas. An H-frame structure mounted within the center of the torus providedsupport for the larger experiments and tape recorders. Mounted on the controlsystem housing, which was located on top of the spacecraft, were sun sensors,horizon scanners, gas nozzles for attitude control, and a command antenna. Useof a stabilization and control system permitted the spacecraft&apos;s orientation tobe controlled to within plus or minus 1 degree for all three axes (pitch, roll,and yaw).The spacecraft carried an advanced vidicon camera system for recording andstoring remote cloudcover pictures, an automatic picture transmission camerafor providing real-time cloudcover pictures, and both high- andmedium-resolution infrared radiometers (HRIR and MRIR) for measuring theintensity and distribution of electromagnetic radiation emitted by andreflected from the earth and its atmosphere. The spacecraft and experimentsperformed normally after launch until July 26, 1966, when the spacecraft taperecorder failed. Its function was taken over by the HRIR tape recorder untilNovember 15, 1966, when it also failed. Some real-time data were collecteduntil January 17, 1969, when the spacecraft mission was terminated owing todeterioration of the horizon scanner used for earth reference.__________Taken from the NSSDC System for Information Retrieval and Storage (SIRS).

text: Deimos-2 is a very-high resolution (75cm pan-sharpened) multispectral optical satellite, fully owned and operated by Deimos Imaging, an UrtheCast company.

The Deimos-2 end-to-end system has been designed to provide a costeffective yet highly responsive service to customers worldwide.

Deimos-2 is the second satellite of the Deimos Earth Observation system, following Deimos-1, which was launched in 2009 and provides mid-resolution, very-wide-swath imagery.

Deimos-2 has been launched on 19 June 2014, with a mission lifetime of at least seven years. It operates from a Sun-synchronous orbit at a mean altitude of 620 km, with a local time of ascending node (LTAN) of 10h30, which allows an average revisit time of two days worldwide (one day at mid-latitudes). The spacecraft design is based on an agile platform for fast and precise off-nadir imaging (up to 30º over nominal scenarios and up to 45º in emergency cases), and it carries a push-broom very-high resolution camera with 5 spectral channels (1 panchromatic, 4 multispectral).

    <skos:definition xml:lang="en">he next-generation commercial imaging satellite of DigitalGlobe Inc. (Longmont, CO, USA) is called WorldView-1, a successor of QuickBird-2 (launch Oct. 18, 2001 - and fully operational as of 2007). In Oct. 2003, DigitalGlobe was awarded a sizeable contract by NGA (National Geospatial-Intelligence Agency) of Washington DC, formerly NIMA (National Imaging and Mapping Agency), to provide high-resolution imagery from the next-generation commercial imaging satellites.The NGA requirements call for imagery with a spatial resolution of 0.5 m panchromatic and 2 m MS (Multispectral) data. The contract award was made within NGA&apos;s NextView program, designed to give the US commercial imaging satellite operators the financing to build their satellites for high-resolution imaging. The WorldView mission is intended to provide imaging services to NGA as well as to the commercial customer base of DigitalGlobe.Spacecraft:BATC (Ball Aerospace and Technologies Corporation) of Boulder, CO, is the prime contractor and integrator of the spacecraft, providing the S/C bus (Ball Commercial Platform BCP-5000) and a WorldView-60 camera. A new feature of the WorldView spacecraft are CMG (Control Moment Gyroscopes) actuators for precise and highly responsive pointing control. The BCP-5000 bus provides increased power, stability, agility, data storage and transmission (over the BCP-2000 bus) as the demand for Earth remote-sensing information becomes more comprehensive. The S/C is 3-axis stabilized. The ADCS (Attitude Determination and Control Subsystem) employs star trackers, IRU (Inertial Reference Unit) and GPS for attitude sensing, and CMGs as actuators. A S/C body-pointing range of ±40º about nadir is provided corresponding to a FOR (Field of Regard) of 775 km in cross-track. An instantaneous pointing accuracy of ≤ 500 m is provided at any start and stop of an imaging sequence. On the ground, the geolocation accuracy of the imagery is 5.8 to 7.6 m without GPCs (Ground Control Points) and 2 m with GPCs (3σ). The agile S/C provides retargeting at a rate of 4.5º/s with an acceleration of 2.5º/s2; it takes 9 s to slew the S/C over a ground distance of 300 km.S/C power of 3.2 kW (EOL) is provided by the solar panels; the battery capacity is 100 Ah. The solar arrays are being articulated into the sun (normal pointing into the sun). The rotational drive assemblies and drive control electronics, referred to as QuAD (Quiet Array Drive), are being provided by Starsys, a subsidiary of SpaceDev, Poway, CA. Unlike traditional stepper motor solar array drives, the QuAD technology provides low disturbance actuation, allowing spacecraft images to be captured at the same time that the solar arrays are being pointed.The S/C bus has dimensions of 3.6 m (high) and 2.5 m in diameter, the span of the deployed panels measures 7.1 m. WorldView-1 has a launch mass of 2500 kg. The mission design life is 7.25 years. Launch: A launch of the WorldView-1 spacecraft took place on Sept. 18, 2007 on a Delta-2920 vehicle from VAFB, CA.Orbit: Sun-synchronous circular orbit, altitude = 496 km (nominal), inclination = 97.2º. The equator crossing time is at 10:30 hours on a descending node. The period is 94.6 minutes. Note: While the low-altitude orbit selection offers better spatial resolutions than a higher one, it requires also more frequent reboosts to maintain the low orbit due to atmospheric drag influences.RF communications: The command data are in S-band at 2 or 64 kbit/s. The housekeeping telemetry and tracking is in X-band at 4, 16, or 32 kbit/s of real-time data, or 524 kbit/s of stored data. The imagery is downlinked in X-band at 800 Mbit/s. The S/C provides a data storage capacity of 2.2 Tbit in solid state memory with EDAC (Error Detection and Correction). A total of 331 Gbit of imagery per orbit may be collected.  In addition, direct (real-time) downlinks to customer sites are available using the same high-speed 800 Mbit/s X-band link. Mission status: In early January 2008, DigitalGlobe announced the general availability of WorldView-1 imagery to its customers after all check-out aspects of the spacecraft and its payload had been completed. 6)• DigitalGlobe delivered its first sample set of high-resolution images on Oct. 15, 2007 and began supplying imagery to the National Geospatial-Intelligence Agency (NGA) on Nov. 26, 2007 (the S/C reached already full operating capacity on Nov. 17. 2007).

    <skos:definition xml:lang="en">EQUATOR-S  is a low-cost mission designed to study the Earth&apos;s equatorialmagnetosphere out to distances of 67000 km and it forms an element of theclosely-coordinated fleet of satellites that comprise the  IASTP  program(http://www-istp.gsfc.nasa.gov/istp/sci_operations/www-sites.html) . It isbased on a simple spacecraft design and carries a science payload consisting ofadvanced instruments that were developed for other IASTP missions. Uniquefeatures of  EQUATOR-S  are its nearly equatorial orbit and its high spin rate.It was launched as an auxiliary payload on an Ariane-4 on December 2nd, 1997.The mission is intended for a two-year lifetime.The idea of an equatorial satellite dates back to NASA&apos;s GGS (Global GeospaceScience) program originally conceived in 1980. When the equatorial element ofthe program was abandoned in 1986 and several subsequent attempts to rescue themission had failed, the Max-Planck-Institut f?r extraterrestrische Physik (MPE)decided in 1991 to fill this gap in the GGS (and in the international IASTP)program because of its interest in the global magnetospheric science, andbecause it provided an opportunity for a test of an advanced instrument, EDI,to measure electric fields with dual electron beams. The realization ofEQUATOR-S was possible through a grant from the German Space Agency DARA(meanwhile part of DLR), that was approved in late 1994, but also throughMPE-internal funds and personnel.

    <skos:definition xml:lang="en">Gemini  9, manned with two astronauts, was the seventh earth-orbiting spacecraft of the Gemini series. The blunt, cone-shaped spacecraft was 3.048  cm  in  diameter  at  the  rear  of  the craft. Primary mission objectives were to demonstrate (1) three rendezvous techniques, (2) an extravehicular  activity  (EVA) to test the astronaut maneuvering unit (AMU),  and  (3)  precision  landing capability. scientific objectives included obtaining zodiacal light and airglow horizon photographs. Two micrometeorite studies were to be carried out, and there were also one medical  and  two  technological experiments. the agena target vehicle failed  to  achieve  orbit,  and  the  agena micrometeorite experiment hardware  was  lost.  Other experiments functioned normally. The three rendezvous techniques were demonstrated, although docking could not be achieved  due  to  a failure of the augmented target-docking shroud to jettison. The EVA was curtailed due to fogging of the visor and energy expended by the astronaut. Reentry was routinely accomplished after 47 orbits on june 6, 1966, within 3.2 km of the target point.Group: Platform_Details   Entry_ID: GEMINI-9   Group: Platform_Identification      Platform_Category: Space Stations/Manned Spacecraft      Platform_Series_or_Entity: GEMINI      Short_Name: GEMINI-9   End_Group   Group: Synonymous_Platform_Names      Short_Name: TITAN II (9)   End_Group   Group: Orbit      Orbit_Inclination: 28.86 degrees      Perigee: 270 km      Apogee: 272 km   End_Group   Creation_Date: 2008-01-24   Online_Resource: http://www.astronautix.com/flights/gemini9.htm   Sample_Image: http://www.astronautix.com/graphics/0/10074373.jpg   Group: Platform_Logistics      Launch_Date: 1966-06-03      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">Spacecraft Brief Description  Gemini 11 was the ninth manned earth-orbiting spacecraft of the Gemini  series.  The  3-day  mission  was  designed  to  achieve a first orbit  rendezvous  and  docking  with the agena target vehicle, to accomplish  two  extravehicular  activity  (EVA)  tests, and to perform spacecraft  maneuvers.  There  were  also  eight scientific and four technological  experiments  on board. The scientific experiments were (1) synergistic  effect  of  zero-g  and  radiation  on white blood cells, (2) synoptic  terrain  photography,  (3)  synoptic  weather photography, (4) nuclear  emulsions,  (5)  airglow  horizon  photography,  (6)  UV  astronomical  photography,  (7)  Gemini  ion  wake  measurement,  and  (8)  dim  sky  photography.  The  experiments  and  the other mission objectives were  successfully  completed.  Reentry  occurred  after 44 orbits using the  first closed-loop automatic reentry mode. The spacecraft landed within  4.8 km of the planned impact point on september 15, 1966.Auxiliary Information  Launch Date and Time : 1966-09-12 14:38:00  Epoch Date and Time :  1966-09-12  Orbit Type :  Geocentric  Apogee(km) :     280.

From a position about 22,300 miles above Earth, the advanced weather satellite will keep an unblinking eye on atmospheric conditions in the Eastern United States and Atlantic Ocean.  [Source: GOES project Office NASA Goddard Space Flight Center, http://goespoes.gsfc.nasa.gov/goes/spacecraft/goes_o_spacecraft.html ]  Geostationary Operational Environmental Satellite (GOES)-O represents a continuation of the newest generation of environmental satellites built by Boeing  for the National Oceanic and Atmospheric Administration (NOAA) under the technical guidance and project management of NASA&apos;s Goddard Space Flight Center, Greenbelt, MD. GOES satellites provide the familiar weather pictures seen on United States television newscasts every day. The GOES imaging and sounding instruments (built by ITT) feature flexible scans for small-scale area viewing in regions of the visible and infrared spectrum allowing meteorologists to improve short-term forecasts. GOES provides nearly continuous imaging and sounding, which allow forecasters to better measure changes in atmospheric temperature and moisture distributions and hence increase the accuracy of their forecasts. GOES environmental information is used for a host of applications, including weather monitoring and prediction models, ocean temperatures and moisture locations, climate studies, cryosphere (ice, snow, glaciers) detection and extent, land temperatures and crop conditions, and hazards detection. The GOES-O&amp;P Imagers have improved resolution in the 13 micrometer channel from 8 km to 4 km. The finer spatial resolution allows an improved cloud-top product, height of atmospheric motion vectors and volcanic ash detection. GOES-O continues the improved image navigation and registration, additional power and fuel lifetime capability, space weather, solar x-ray imaging, search and rescue, and communication services as provided on GOES-13.  GOES-P is also in ground storage following the completion of environmental testing and is prepared for an April 2009 launch readiness with a July 2010, engineering handover date requirement.

Old Value=NOAA-2 was launched in October 1972 and was the first in a series of
reconfigured ITOS satellites launched with new meteorological sensors
onboard to expand the operational capability of the ITOS
system. NOAA-2 was not equipped with conventional TV cameras. It was
the first operational weather satellite to rely solely upon
radiometric imaging to obtain cloudcover data.  The primary objective
was to provide global daytime and nighttime direct readout real-time
cloudcover data on a daily basis. The sun-synchronous spacecraft was
also capable of supplying global atmospheric temperature soundings and
very high resolution infrared cloudcover data for selected areas in
either a direct readout or a tape-recorder mode. A secondary objective
was to obtain global solar-proton flux data on a real-time daily
basis.  The sensors were mounted on the satellite baseplate with their
optical axes directed vertically earthward. The nearly cubical
spacecraft measured 1 by 1 by 1.2 m. The satellite was equipped with
three curved solar panels that were folded during launch and deployed
after orbit was achieved. Each panel measured over 4.2 m in length
when unfolded and was covered with approximately 3500 solar cells
measuring 2 by 2 cm. The dynamics and attitude control system
maintained desired spacecraft orientation through gyroscopic
principles incorporated into the satellite design. Earth orientation
of the satellite body was maintained by taking advantage of the
precession induced from a momentum flywheel so that the satellite body
precession rate of one revolution per orbit provided the desired
&apos;earth-looking&apos; attitude. Minor adjustments in attitude and
orientation were made by means of magnetic coils and by varying the
speed of the momentum flywheel.
The primary sensors consisted of a Very High Resolution Radiometer
(VHRR), Vertical Temperature Profile Radiometer (VTPR), and a Scanning
Radiometer (SR).  The spacecraft operated satisfactorily until March
18, 1974, when the VTPR failed. NOAA-2 was then placed in a marginal
standby mode from March 19 to July 1, 1974. It was then used as the
operational NOAA satellite until October 16, 1974, when it was again
placed in a marginal standby mode. The spacecraft was deactivated on
January 30, 1975.

Old Value=NOAA-2 was launched in October 1972 and was the first in a series of
reconfigured ITOS satellites launched with new meteorological sensors
onboard to expand the operational capability of the ITOS
system. NOAA-2 was not equipped with conventional TV cameras. It was
the first operational weather satellite to rely solely upon
radiometric imaging to obtain cloudcover data.  The primary objective
was to provide global daytime and nighttime direct readout real-time
cloudcover data on a daily basis. The sun-synchronous spacecraft was
also capable of supplying global atmospheric temperature soundings and
very high resolution infrared cloudcover data for selected areas in
either a direct readout or a tape-recorder mode. A secondary objective
was to obtain global solar-proton flux data on a real-time daily
basis.  The sensors were mounted on the satellite baseplate with their
optical axes directed vertically earthward. The nearly cubical
spacecraft measured 1 by 1 by 1.2 m. The satellite was equipped with
three curved solar panels that were folded during launch and deployed
after orbit was achieved. Each panel measured over 4.2 m in length
when unfolded and was covered with approximately 3500 solar cells
measuring 2 by 2 cm. The dynamics and attitude control system
maintained desired spacecraft orientation through gyroscopic
principles incorporated into the satellite design. Earth orientation
of the satellite body was maintained by taking advantage of the
precession induced from a momentum flywheel so that the satellite body
precession rate of one revolution per orbit provided the desired
&apos;earth-looking&apos; attitude. Minor adjustments in attitude and
orientation were made by means of magnetic coils and by varying the
speed of the momentum flywheel.
The primary sensors consisted of a Very High Resolution Radiometer
(VHRR), Vertical Temperature Profile Radiometer (VTPR), and a Scanning
Radiometer (SR).  The spacecraft operated satisfactorily until March
18, 1974, when the VTPR failed. NOAA-2 was then placed in a marginal
standby mode from March 19 to July 1, 1974. It was then used as the
operational NOAA satellite until October 16, 1974, when it was again
placed in a marginal standby mode. The spacecraft was deactivated on
January 30, 1975.

    <skos:definition xml:lang="en">[Source: NASA NSSDC, http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1978-062A ]GOES 3 was launched in June 1978 and was a NASA-developed, NOAA-operated, geosynchronous, and operational spacecraft.  The cylindrically shaped spacecraft measured 190.5 cm in diameter and 230 cm in length, exclusive of a magnetometer that extended an additional 83 cm beyond the cylinder shell.  The primary structural members were a honeycombed equipment shelf and thrust tube. The VISSR telescope was mounted on the equipment shelf and viewed the Earth through a special aperture in the side of the spacecraft.  A support structure extended radially out from the thrust tube and was affixed to the solar panels, which formed the outer walls of the spacecraft and provided the primary source of electrical power.  Located in the annulus-shaped space between the thrust tube and the solar panels were stationkeeping and dynamics control equipment, batteries, and most of the SEM equipment.  Proper spacecraft attitude and spin rate (approximately 100 rpm) were maintained by two separate sets of jet thrusters mounted around the spacecraft equator and activated by ground command.  The spacecraft used both UHF-band and S-band frequencies in its telemetry and command subsystem.  A low-power VHF transponder provided telemetry and command during launch and then served as a backup for the primary subsystem once the spacecraft attained orbit. The spin-stabilized spacecraft carried a visible infrared spin-scan radiometer, meteorological data collection and transmission system, space environment monitor, and a biaxial fluxgate magnetometer.  It operated at 135 degrees West as GOES-WEST.For more information on GOES satellites:http://www.oso.noaa.gov/goes/Group: Platform_Details   Entry_ID: GOES-3   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: GOES (Geostationary Operational Environmental Satellite)      Short_Name: GOES-3      Long_Name: Geostationary Operational Environmental Satellite 3   End_Group   Group: Synonymous_Platform_Names      Short_Name: GOES C      Short_Name: 10953   End_Group   Group: Platform_Associated_Instruments      Short_Name: SXM      Short_Name: VISSR      Short_Name: SEM      Short_Name: MAGNETOMETERS   End_Group   Group: Orbit      Orbit_Type: GEO &gt; Geosynchronous &gt; Geostationary   End_Group   Creation_Date: 2007-10-04   Online_Resource: http://www.oso.noaa.gov/goes/   Online_Resource: http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1978-062A   Sample_Image: http://library01.gsfc.nasa.gov/gdprojs/images/goes.jpg   Group: Platform_Logistics      Launch_Date: 1978-06-16      Launch_Site: CAPE CANAVERAL/KENNEDY SPACE CENTER, USA      Primary_Sponsor: USA/NASA      Primary_Sponsor: USA/NOAA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">SSTL developed the NigeriaSat-1 enhanced microsatellite during a know-how and technology transfer program for the Federal Ministry of Science and Technology (FMST) of Nigeria. NigeriaSat-1 is the first step in FMSTs plan to develop Nigerias national space infrastructure. The NigeriaSat-1 programme included the satellite, a mission control station in Abuja, Nigeria and hands-on training at Surrey for a team of Nigerian engineers. During the project, Nigeria formed a National Space Research and Development Agency (NASRDA), which now manages the NigeriaSat-1 program.                NigeriaSat-1 is a satellite of the standard Disaster Monitoring Constellation (DMC) design. It carries an optical imaging payload developed by SSTL to provide 32-m ground resolution with an exceptionally wide swath width of over 640 km. The payload uses green, red and near infrared bands equivalent to Landsat TM+ bands 2, 3 and 4. Images are stored in a 1-gigabyte solid-state data recorder and returned via an 8-Mbps S-band downlink.NigeriaSat-1 can image scenes as large as 640 x 560 km, providing unparalleled wide-area, medium-resolution data. The data will be used within Nigeria to monitor pollution, land use and other medium-scale phenomena. .                In addition, NASRDA have joined the Disaster Monitoring Constellation (DMC) Consortium, and images from NigeriaSat-1 will be available to disaster relief agencies world-wide through the DMC data sharing system.NigeriaSat-1 was launched in September 2003 from Pletsesk on a Kosmos launch vehicle, one of three satellites simultaneously launched to complete the first phase of the Disaster Monitoring Constellation, to provide medium-resolution imagery with daily worldwide revisit.The objective is to provide a daily global imaging capability at medium resolution (30-40 m), in 3-4 spectral bands, for rapid-response disaster monitoring and mitigation.Group: Platform_Details   Entry_ID: NIGERIASAT-1   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: NIGERIASAT-1   End_Group   Group: Platform_Associated_Instruments      Short_Name: SLIM-6   End_Group   Group: Orbit      Orbit_Altitude: 686 km      Orbit_Inclination: 98 degrees      Period: 98.4 min      Perigee: 675 km      Apogee: 692 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2008-06-02   Online_Resource: http://www.dmcii.com/   Online_Resource: http://www.skyrocket.de/space/doc_sdat/nigeriasat-1.htm   Online_Resource: https://directory.eoportal.org/web/eoportal/satellite-missions/n/nigeriasat-2   Group: Platform_Logistics      Launch_Date: 2003-09-27      Launch_Site: Plesetsk Cosmodrome, Russia      Primary_Sponsor: Nigeria      Primary_Sponsor: SSTL   End_GroupEnd_Group</skos:definition>

    The  Insat-1  satellite program incorporated two three-axis stabilized
    spacecraft  in  geostationary  orbit  (Insat-1A  at  74  degrees E and
    Insat-1B  at  94  degrees E) with a host of ground stations throughout
    India.   The  Insat-1A  satellite,  built  by  the  Ford Aerospace and
    Communications   Corporation,   was   designed   to  provide  combined
    telecommunications, direct TV broadcast, and meteorological service to
    India&apos;s  civilian  community  over  a  7-year-in-orbit  lifespan.  The
    telecommunications  package  provided two-way, long distance telephone
    circuits and direct radio and TV broadcasting to the remotest areas of
    India.     The   meteorology   package  was  composed  of  a  scanning
    very-high-resolution,   two-channel   radiometer   (VHRR)  to  provide
    full-frame,  full-earth coverage every 30 minutes.  The visual channel
    (0.55-0.75  micrometer)  had a 2.75-km resolution while the IR channel
    (10.5-12.5  micrometers)  had an 11-km resolution.  Using the Insat TV
    capability,  early  warnings  of  impending  disasters  (i.e., floods,
    storms,  etc.)  could  directly reach the civilian population, even in
    remote  areas.   The  Insat-1A  also  had  a data channel for relaying
    meteorological,  hydrological,  and oceanographic data from unattended
    land-based  or ocean-based data collection and transmission platforms.

The    telecommunications  package  provided two-way, long distance telephone    circuits and direct radio and TV broadcasting to the remotest areas of    India.     The   meteorology   package  was  composed  of  a  scanning    very-high-resolution,   two-channel   radiometer   (VHRR)  to  provide    full-frame,  full-earth coverage every 30 minutes.  The visual channel    (0.55-0.75  micrometer)  had a 2.75-km resolution while the IR channel    (10.5-12.5  micrometers)  had an 11-km resolution.  Using the Insat TV    capability,  early  warnings  of  impending  disasters  (i.e., floods,    storms,  etc.)  could  directly reach the civilian population, even in    remote  areas.   The  Insat-1A  also  had  a data channel for relaying    meteorological,  hydrological,  and oceanographic data from unattended    land-based  or ocean-based data collection and transmission platforms.    *Insat-1A was abandoned in September 1983 when its attitude     control propellant was exhausted*  Auxiliary Information    Launch Date and Time : 1982-04-10 06:47:00    Epoch Date and Time :  1982-04-11    Orbit Type :  Geocentric    Apogee(km) :   35784.

    <skos:definition xml:lang="en">[Source: NASA Space Science Data Center (NSSDC), http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1977-048A ]GOES 2 was a NASA-developed, NOAA-operated, geosynchronous, and operational spacecraft. The spin-stabilized spacecraft carried (1) a visible infrared spin-scan radiometer (VISSR) to provide high-quality day/night cloudcover data and to take radiance-derived temperatures of the earth/atmosphere system, (2) a meteorological data collection and transmission system to relay processed data from central weather facilities to APT-equipped regional stations and to collect and retransmit data from remotely located earth-based platforms, and (3) a space environment monitor (SEM) system to measure proton, electron, and solar X-ray fluxes and magnetic fields. The cylindrically shaped spacecraft measured 190.5 cm in diameter and 230 cm in length, exclusive of a magnetometer that extended an additional 83 cm beyond the cylinder shell. The primary structural members were a honeycombed equipment shelf and thrust tube. The VISSR telescope was mounted on the equipment shelf and viewed the earth through a special aperture in the side of the spacecraft. A support structure extended radially out from the thrust tube and was affixed to the solar panels, which formed the outer walls of the spacecraft and provided the primary source of electrical power. Located in the annulus-shaped space between the thrust tube and the solar panels were stationkeeping and dynamics control equipment, batteries, and most of the SEM equipment. Proper spacecraft attitude and spin rate (approximately 100 rpm) were maintained by two separate sets of jet thrusters mounted around the spacecraft equator and activated by ground command. The spacecraft used both UHF-band and S-band frequencies in its telemetry and command subsystem. A low-power VHF transponder provided telemetry and command during launch and then served as a backup for the primary subsystem once the spacecraft attained synchronous orbit.

    <skos:definition xml:lang="en">AlSAT-1 is part of an international (BNSC-UK, China, Nigeria and Thailand) disaster-monitoring constellation (DMC) of 6 micro-satellites dedicated for monitoring disasters throughout the earth, such as floods, fires, earthquakes, volcanoes, large-scale industrial accidents and civil strife. When there are no disasters, AlSAT-1 will be used for Algerian purposes such as monitoring desertification, industrial and marine pollution, agricultural monitoring, geophysics mapping and fire detection. The nature of the mission is that the 6 micro-satellites, when coordinated together, can produce a daily revisit with a 32 m resolution multi-spectral imaging and 600 km ground track. AlSAT-1 uses the flight proven modular SSTL bus from previous missions but will carry a push broom imager for the first time on SSTL micro-satellites. As a part of the constellation and to maintain a daily coverage, AlSAT-1 is equipped with a propulsion system for orbit corrections.AlSAT-1&apos;s main payload a multi-spectral earth observation imager. Digital store and forward communications can be experienced between two points and autonomous GPS positioning techniques also accomplished.The Algerian satellite is one of SSTLs new generation microsatellites in a sense that it carries a new type of push broom sensors. These types of sensors can previously only be found in larger commercial satellites. Because of the advance in electronics and semiconductor integration on a single chip, nowadays these sensors are being implemented by SSTL on microsatellites.AlSAT-1 is designed to view the earth surface with a 32 m resolution in three spectral bands (R, G, NIR) and a ground track of 600 km. The spectral bands were chosen to correspond to those used by commercial satellites in the following wavelengths (in micrometer) 0.5-0.6 micrometer, 0.6-0.7 , 0.7-0.8 ). The imaging system comprises two cameras for each spectral band and two sensors with 10 000 pixels each. This represents a huge quantity of data for the electronics on board (processors, SSDR, fast clocks) to deal with.The cameras provide 32 m ground resolution in 3 spectral bands capable of giving detailed information on earth resources, land use and effects of pollution and natural disasters using 2x10 000 pixels linear array detectors digitized to 8 bits radiometric resolution (256 levels). The image swath width is 600 km and the imager can collect images continuously along the flight track. The images are stored on board the microsatellite via the On Board Computer (OBC) and Controller Area Network (CAN) in the 2x512 Mbytes Solid State Data Recorder (SSDR) for later transmission to ground via digital packet error controlled links at 8 Mbit/s in S-band.However, on the satellite there will be an option to do windowing. By using this technique, we can take images of 100x100 km and thus extend the track range.Group: Platform_Details   Entry_ID: ALSAT-1   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: ALSAT-1   End_Group   Group: Platform_Associated_Instruments      Short_Name: SLIM-6   End_Group   Group: Orbit      Orbit_Altitude: 700      Orbit_Inclination: 98      Period: 98.4      Perigee: 676      Apogee: 691      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2008-06-02   Online_Resource: https://directory.eoportal.org/web/eoportal/satellite-missions/a/alsat-2   Group: Platform_Logistics      Launch_Date: 2002-11-28      Launch_Site: Plesetsk Cosmodrome, Russia      Primary_Sponsor: Algeria   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">NOAA-5 was launched in July 1976 and was one in a series ofreconfigured ITOS satellites launched with new meteorological sensorsonboard to expand the operational capability of the ITOS system.  Theprimary objective was to provide global daytime and nighttime directreadout real-time cloudcover data on a daily basis. Thesun-synchronous spacecraft was also capable of supplying globalatmospheric temperature soundings and very high resolution infraredcloudcover data for selected areas in either a direct readout or atape-recorder mode. A secondary objective was to obtain globalsolar-proton flux data on a real-time daily basis. The sensors weremounted on the satellite baseplate with their optical axes directedvertically earthward. The nearly cubical spacecraft measured 1 by 1 by1.2 m. The satellite was equipped with three curved solar panels thatwere folded during launch and deployed after orbit was achieved. Eachpanel measured over 4.2 m in length when unfolded and was covered withapproximately 3500 solar cells measuring 2 by 2 cm. The dynamics andattitude control system maintained desired spacecraft orientationthrough gyroscopic principles incorporated into the satellitedesign. Earth orientation of the satellite body was maintained bytaking advantage of the precession induced from a momentum flywheel sothat the satellite body precession rate of one revolution per orbitprovided the desired &apos;earth-looking&apos; attitude. Minor adjustments inattitude and orientation were made by means of magnetic coils and byvarying the speed of the momentum flywheel.The primary sensors consisted of a Very High Resolution Radiometer(VHRR), Vertical Temperature Profile Radiometer (VTPR), and a ScanningRadiometer (SR).  The spacecraft was placed in a sun-synchronous orbitwith equatorial crossing of the ascending node near 8:30 a.m. localtime.__________Taken from the NSSDC System for Information Retrieval and Storage (SIRS).

    <skos:definition xml:lang="en">EROS-B is a high-resolution commercial imaging minisatellite mission of ImageSat International N.V. headquartered in the Netherlands Antilles (Cayman Islands), with offices in Limassol, Cyprus, and in Tel Aviv, Israel. The overall objective is to provide high-resolution imagery to the customer base.Spacecraft:The EROS-B series S/C structure is identical to that of EROS-A, based on the Ofeq platform of Israel&apos;s Defense Ministry, and designed and built by Israel Aircraft Industries Ltd. (IAI/MBT). The deployed S/C structure is 2.3 m high and 4.0 m wide. The S/C is is 3-axis stabilized and the light/rigid design of the EROS satellite family allows for a great degree of platform agility. The spacecraft is very agile, a body-pointing capability of ±45º from nadir is provided in all directions, supporting the daily data acquisition plan. The S/C attitude is sensed and controlled as done with EROS-A. In addition, there is a star sensor for the B satellite series. The nominal S/C design life is six years.The nominal S/C launch mass is ~290 kg; however, additional onboard fuel (up to 60 kg) is sufficient for S/C operations of up to 10 years. This increased the spacecraft launch mass to about 350 kg. Orbit: Sun-synchronous circular orbit, mean altitude = 500 km, inclination = 97.4º, local time of descending node (LTDN) at 14:00 hours. - Note: The orbits of EROS-A and EROS-B are phased in the same orbital plane thereby increasing the revisit time of the constellation.Launch: A launch of EROS-B took place on April 25, 2006 on a Start-1 launch vehicle from the Svobodny Cosmodrome in eastern Siberia (location at: 51.4º N, 128.3º E). 3)RF communications: Imagery is transmitted in X-band at a rate of 280 Mbit/s (downlink) to the ground receiving stations, using a 1.5 W transmitter and one of the two existing two-axis gimbaled directional antennas. The EROS satellites are monitored/operated in S-Band (TT&amp;C) via a single ground control station (GCS), located at IAI/MBT in Israel (3 to 4 passes per day and per satellite are in station visibility). The S-band data rate is either 2.5 or 15 kbit/s selectable by the GCS.ImageSat has a global network of ground segment infrastructure, for real-time image data acquisition. This network is comprised of the ImageSat Central Ground Control Station, a network of EROS-compatible Ground Receiving Stations on 5 continents and EROS-compatible Ground Control Stations based at exclusive customers&apos; premises. Sensor complement: (PIC-2)PIC-2 (Panchromatic Imaging Camera-2), designed and developed by ElOp (Electro Optical Industries) of Rehovot, Israel, a subsidiary of Elbit Systems Ltd. The EROS-B series imager instrument features CCD pushbroom technology in combination with a TDI (Time Delay Integration) scheme in its focal plane, a cumulative expose concept of each ground image line by a CCD detector array, to improve the SNR value (an important issue for high-resolution imaging). The instrument uses also a Cassegrain telescope with an aperture of 50 cm in diameter and a focal length of 5 m (folded optics). FOV = 1.5º. The PIC-2 instrument is rigidly mounted to the S/C structure looking into the nadir direction, thus permitting a body-pointing observation scheme. he CCD pushbroom detector array provides 10,000 pixels per line and a total of 96 lines for selectable TDI observation support. Pushbroom scanning is provided for panchromatic imagery only in the spectral range of 0.5 - 0.9 μm. The ground sampling distance (GSD) is 0.70 m, the swath width is 7 km at nadir. The data is quantized at 10 bit/sample.The imager instrument of EROS-B spacecraft can be operated in either asynchronous or in synchronous imaging mode. In synchronous mode, the S/C platform keeps a constant pointing angle toward the Earth&apos;s surface. In asynchronous mode, imaging by the detector array is performed in a &apos;step-and-stare&apos; fashion, i.e., by slewing the S/C platform in the along-track direction (this permits in particular the generation of mosaics as well as the support of stereo imaging of targets of interest).Information obtained from http://www.eoportal.org/Group: Platform_Details   Entry_ID: EROS-B1   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Short_Name: EROS-B1   End_Group   Group: Platform_Associated_Instruments      Short_Name: CAMERAS   End_Group   Group: Orbit      Orbit_Altitude: 500      Orbit_Inclination: 97.4      Period: 94.7      Perigee: 503.5      Apogee: 514.7      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2008-07-09   Online_Resource: http://directory.eoportal.org/get_announce.php?an_id=12460   Group: Platform_Logistics      Launch_Date: 2006-04-25      Launch_Site: Svobodny Cosmodrome, Russia      Design_Life: 10 years      Primary_Sponsor: ImageSat International, Israel   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The Dynamics Explorer (DE) mission&apos;s general objective is to investigate the strong interactive processes coupling the hot, tenuous, convecting plasmas of the magnetosphere and the cooler, denser plasmas and gases corotating in the earth&apos;s ionosphere, upper atmosphere, and plasmasphere. Two satellites, DE 1 and DE 2, were launched together and were placed in polar coplanar orbits, permitting simultaneous measurements at high and low altitudes in the same field-line region. The DE 1 spacecraft (high-altitude mission) uses an elliptical orbit selected to allow (1) measurements extending from the hot magnetospheric plasma through the plasmasphere to the cool ionosphere; (2) global auroral imaging, wave measurements in the heart of the magnetosphere, and crossing of auroral field lines at several earth radii; and (3) measurements for significant periods along a magnetic field flux tube. The spacecraft approximated a short polygon 137 cm in diameter and 115 cm high. The antennas in the X-Y plane measured 200-m tip-to-tip, and on the Z-axis are 9 meters tip-to-tip. Two six-meter booms are provided for remote measurements. Power is supplied by a solar cell array, mounted on the side and end panels. The spacecraft is spin stabilized, with the spin axis normal to the orbital plane, and the spin rate at ten plus or minus 0.1 rpm. A pulse code modulation (PCM) telemetry data system is used that operates in real time or in a tape-recorder mode. Data have been acquired on a science-problem-oriented basis, with closely coordinated operations of the various instruments, both satellites, and supportive experiments. Data acquired from the instruments are temporarily stored on tape recorders before transmission at an 8:1 playback-to-record ratio. Additional operational flexibility allows a playback-to-record ratio of 4:1. The primary data rate is 16,384 bits per second. Since commands are stored in a command memory unit, spacecraft operations are not real time, except for the transmission of the wideband analog data from the Plasma Wave Instrument (81-070A-02). On October 22, 1990 science operations were terminated. On February 28, 1991 Dynamics Explorer 1 operations were offically terminated.

Old Value=Explorer 17 was a spin-stabilized sphere 0.95 m in diameter.  The spacecraft was vacuum sealed in order to prevent contamination of the local atmosphere.  Explorer 17 carried four pressure gauges for the measurement of total neutral particle density, two mass spectrometers for the measurement of certain neutral particle concentrations, and two electrostatic probes for ion concentration and electron temperature measurements.  Battery power failed on July 10, 1963. Three of the four pressure gauges and both electrostatic probes operated normally.  One spectrometer malfunctioned, and the other operated intermittently.

The icebreaker, RSV Nuyina, is the main lifeline to Australia’s Antarctic and sub-Antarctic research stations and the central platform of our Antarctic and Southern Ocean scientific research.

Nuyina enables us to cross thousands of kilometres of the world’s stormiest seas, navigate through Antarctica’s formidable sea ice barrier, and live and work for extended periods on the coldest, driest and windiest continent on earth – some of the harshest conditions in the world.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

    <skos:definition xml:lang="en">In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &apos;Compass&apos;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.</skos:definition>

    <skos:definition xml:lang="en">EROS-A (of Ofeq-3 heritage) is a high-resolution commercial imaging satellite of ImageSat International N.V. headquartered at Limassol, Cyprus, and designed and built by Israeli Aircraft Industries Ltd. (IAI). The overall objective is to launch and operate a constellation of high-resolution commercial satellites, primarily for intelligence and national security applications and to serve a global customer base. The spaceborne remote sensing technology for the EROS family was approved by the government of Israel in Oct. 1996. The EROS program offers a combination of services and products tailored to meet specific customer requirements and budgets: • The option to acquire exclusive imaging rights over a defined footprint or the ability to acquire imagery on an exclusive basis.• Rapid delivery of imagery to the customer, either through direct downlink, electronic transfer or courier.• Provision of low-cost imagery products to support applications in many fields.Spacecraft:The EROS-A satellite structure consists of low-mass composite material with passive thermal control, it is three-axis stabilized. Attitude control and navigation is performed using horizon sensors, sun sensors, gyros and magnetometer, four reaction wheels and thrusters. The pointing accuracy is &lt;0.1º in all three axes, attitude stabilization is &lt; 40 µrad/s, the jitter is &lt; 0.2 µrad. S/C mass = 260 kg (178 kg S/C bus, 42 kg of instrument mass and 30 kg of hydrazine), solar panel power (silicon array, fixed panels) = 450 W (EOL), plus 14 Ah NiCd batteries for eclipse operation, the bus power consumption at imaging session is 300 W. S/C design life = 4 years, however the estimated operational life of the satellite is ten years. RF communications: Imagery is transmitted in X-band at a rate of 70 Mbit/s (RF downlink) to the ground receiving stations, using a 1.5 W transmitter and one of the two existing two-axis gimbaled directional antennas. The EROS satellites are monitored/operated in S-Band (TT&amp;C) via a single ground control station (GCS), located at IAI/MBT in Israel (3 to 4 passes per day and per satellite are in station visibility). The S-band data rate is either 2.5 or 15 kbit/s selectable by the GCS.ImageSat has a global network of ground segment infrastructure, for real-time image data acquisition. This network is comprised of the ImageSat Central Ground Control Station, a network of EROS-compatible Ground Receiving Stations on 5 continents and EROS-compatible Ground Control Stations based at exclusive customers&apos; premises (see SOP Program).The EROS A satellite has limited availability of onboard source data storage, as the satellite was designed to cater to customers acquiring real-time, exclusive imaging and download rights over a defined geographic footprint, in view of their own EROS-compatible GRS (Ground Receiving Stations).Operational capabilities/services primarily include:• Satellite Operating Partner (SOP) Program. This service provides a dedicated regional satellite with local customer tasking. SOP receiving ground stations are able to plan, to generate and to transmit imaging commands to the satellite and to download imagery in real-time.• PAS (Priority Acquisition Service) Program. The service provides highest priority tasking of the EROS satellite, in areas not previously acquired by SOP Customers.• Non-exclusive acquisitions. ImageSat sells EROS imagery on a non-exclusive basis to customers for civilian applications, such as mapping, disaster planning and monitoring, environmental management, homeland security and border control, and a range of development-related projects. aunch: EROS-A was launched on a Russian Start-1 launcher on Dec. 5, 2000 from the Svobodny Cosmodrome in eastern Siberia.Orbit for EROS-A: Circular sun-synchronous orbit, altitude 480 km, inclination = 97.3º, period = 94.7 minutes, local time of descending node at 10:00 hours. The revisit capability at at latitude of 10º within a 15º cone is within 10.5 days. A revisit period/satellite at latitude of 10º is 4.5 days within a 30º cone, and only 2.5 days within a 45º cone.Operational status of mission: The EROS-A spacecraft and all subsystems are operating nominally as of 2008. Operations are expected to last until 2010. Background on EROS program:EROS is a program of ImageSat International, N.V., formerly WIS (West Indian Space) Ltd., Cayman Islands. The name change took place in June 2000. ImageSat was re-incorporated in Curacao, Netherlands Antilles. ImageSat&apos;s ownership includes: Israel Aircraft Industries (IAI) of Tel-Aviv (owned by the Israeli government), Elbit Systems Ltd. of Haifa, and private investors from Europe and the United States.• EROS-B was launched on April 25, 2006 on a Start-1 launch vehicle from the Svobodny Cosmodrome in eastern Siberia• A third satellite, EROS C, will offer comparable panchromatic resolution to EROS B, as well as multispectral resolution of 2.8 m GSD; it is planned for launch in 2009.

experimental marine biology and was specifically built to conduct this research along the
Australian Great Barrier Reef, the Amazon River and Bering Sea. To meet the latter requirement,
the vessel’s hull was ice strengthened to allow it to operate around the ice edge and in ice
conditions. In 1966 and 1967, the vessel operated in tropical waters of the Great Barrier Reef and
Amazon River. In 1968 it proceeded to the Bering Sea for operations. It was soon learned that
the vessel lacked the power to penetrate deeply into the ice pack unless escorted by icebreaker.
Its shortcomings pointed out the need for a larger more capable icebreaking research and this was
the initial impetus to the design of the ARRV.

    <skos:definition xml:lang="en">The SPOT-3 (Satellite Pour l&apos;Observation de la Terre) spacecraft waslaunched in September 26,1993.  SPOT-3 is a earth observationsatellite with a ground resolution better than that of the Landsatseries satellites. The main applications for the images returned bythe third SPOT mission are land-use studies, agriculture and forestryresources, mineral and oil resources, and cartography. The three-axisstabilized satellite operates in a circular sun-synchronous near-polarorbit for a design lifetime of 2 years.Orbital Characteristics-        Orbital Period:  101.20 m        Inclination:  98.60 degrees        Periapsis:    819.00 km              Apoapsis:  846.00 kmThe spacecraft dimensions are 2 x 2 x 3.5 m and 15.60 m for theoverall length of the deployed solar panel. SPOT-3 consists of twoparts: (1) the bus, a standard multipurpose platform, and (2) thepayload. The bus provides housekeeping information and an onboardcomputer. The payload is mounted on one of the side panels of thebus. It consists of two identical high-resolution visible (HRV)imaging instruments and a package comprising two magnetic-tape datarecorders and a telemetry transmitter. The HRV imaging instrumentobserves in three spectral bands (in the visible and near infraredregions) with a ground resolution of 20 m, and/or in a broaderspectral band (panchromatic black and white) with a ground resolutionof 10 m. The pattern of successive ground tracks is repeated exactlyat 26-day intervals. The SPOT-3 instrument package has the provisionfor off-nadir viewing which should be particularly useful formonitoring localized phenomena evolving on a relatively shorttimescale. Also, the satellite provides the capability for recordingstereoscopic pairs of images of a given area during successivesatellite passes.Group: Platform_Details   Entry_ID: SPOT-3   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: SPOT      Short_Name: SPOT-3      Long_Name: Systeme Probatoire Pour l&apos;Observation de la Terre-3   End_Group   Group: Synonymous_Platform_Names      Short_Name: SPOT-3      Short_Name: 22823   End_Group   Group: Platform_Associated_Instruments      Short_Name: DORIS      Short_Name: POAM II      Short_Name: HRV   End_Group   Group: Orbit      Orbit_Inclination: 98.6°      Period: 101.20 minutes      Perigee: 819.0 km      Apogee: 846.0 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-11-13   Online_Resource: http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1993-061A   Online_Resource: http://www.cnes.fr/web/1417-spot-1-to-5.php   Online_Resource: http://www.spot.com/   Group: Platform_Logistics      Launch_Date: 1993-09-26      Launch_Site: Kourou, French Guiana      Design_Life: 2 YEARS      Primary_Sponsor: France/CNES   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">The main objective of the HINOTORI mission was the detailed study of solar flares during solar maximum. Principal investigations were (1) imaging of solar flare X rays in the range 10 to 40 keV by means of rotating modulation collimators and (2) spectroscopy of X-ray emission lines from highly ionized iron in solar flares in the range 1.7 to 2.0 A by means of a Bragg spectrometer. Wavelength scanning was achieved by the spacecraft revolution, with an offset pointing of the spin axis with respect to the sun. Investigations (1) and (2) each had a time resolution of 6 s. In addition, the following investigations were included: three solar flare X-ray monitors that recorded the time profile and spectrum of the X-ray flares in the range 2 to 20 keV, a solar flare gamma-ray detector for the range 0.2 to 9.0 MeV, a particle detector that monitored electron flux above 100 keV, and plasma probes for the measurement of electron density and temperature.

Old Value=The Cessna Citation (CE-550) is a versatile twin-engine jet aircraft modified for acquiring remote sensing imagery. The aircraft is equipped with two equal sized camera ports which can support a wide variety of remote sensing configurations including large format aerial photography as well as data collection for digital cameras, hyperspectral, multispectral, and LIDAR systems.

Standard configuration includes space for two pilots, two equipment operators, and a scientific equipment rack. The aircraft can accommodate additional passengers depending on the amount of scientific equipment. The aircraft&apos;s unique side-by-side sensor port modification allows two different sensors to collect data simultaneously. The sensor ports have glass optical flats that allow the cabin to remain pressurized. Additionally, two high-precision GPS antennas provide signals to user receivers.

The Citation primarily supports the Remote Sensing Division of the National Geodetic Survey, collecting remote sensing data in support of coastal mapping and remote sensing research. Imagery acquired onboard the Citation is used for updating the shoreline and shore features on NOAA&apos;s nautical charts. The Citation also serves as an emergency responder during hurricane season by collecting digital photography of damaged areas caused by hurricane landfall.

    <skos:definition xml:lang="en">The SPOT-1 (Satellite Pour l&apos;Observation de la Terre) spacecraft waslaunched on February 22, 1986.  SPOT-1 is an earth observation satellitewith a greater ground resolution than that of the Landsat series satellites.The main applications for the images returned by the first SPOT mission areland-use studies, agriculture and forestry resources, mineral and oilresources, and cartography. The three-axis stabilized satellite operates ina circular sun-synchronous near-polar orbit for a design lifetime of 2 years.Orbital Characteristics-        Orbital Period:  101.40 m        Inclination:  98.70 degrees        Eccentricity:  0.00101        Periapsis:    815.00 km              Apoapsis:  829.60 kmThe spacecraft dimensions are 2 x 2 x 3.5 m and 15.60 m for the overalllength of the deployed solar panel. SPOT-1 consists of two parts:(1) the bus, a standard multipurpose platform, and (2) the payload. Thebus provides housekeeping information and an onboard computer. The payloadis mounted on one of the side panels of the bus.SPOT-1 consists of two identical high-resolution visible (HRV)imaging instruments and a package comprising two magnetic-tape data recordersand a telemetry transmitter. The HRV imaging instrument observes in threespectral bands (in the visible and near infrared regions) with a groundresolution of 20 m, and/or in a broader spectral band (panchromatic black andwhite) with a ground resolution of 10 m. The pattern of successive groundtracks is repeated exactly at 26-day intervals. The SPOT-1 instrument packagehas the provision for off-nadir viewing which should be particularly useful formonitoring localized phenomena evolving on a relatively short timescale.SPOT-1, also, provides the capability for recording stereoscopic pairs ofimages of a given area during successive satellite passes.*NOTE-SPOT1 is used for technological experiments such as : refocusing,batteries, etc,...*NOTE-SPOT1 is no more used for commercial image acquisition.Group: Platform_Details   Entry_ID: SPOT-1   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: SPOT      Short_Name: SPOT-1      Long_Name: Systeme Probatoire Pour l&apos;Observation de la Terre-1   End_Group   Group: Synonymous_Platform_Names      Short_Name: SPOT-1      Short_Name: SPOT-A      Short_Name: 16613   End_Group   Group: Platform_Associated_Instruments      Short_Name: HRV   End_Group   Group: Orbit      Orbit_Inclination: 98.7°      Period: 101.4 minutes      Perigee: 815.0 km      Apogee: 829.6 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-11-13   Online_Resource: http://nssdc.gsfc.nasa.gov/nmc/spacecraftOrbit.do?id=1986-019A   Online_Resource: http://www.cnes.fr/web/1417-spot-1-to-5.php   Online_Resource: http://www.spot.com/   Sample_Image: http://msl.jpl.nasa.gov/QuickLooks/pictures/spot1.gif   Group: Platform_Logistics      Launch_Date: 1986-02-22      Launch_Site: Kourou, French Guiana      Primary_Sponsor: France/CNES   End_GroupEnd_Group</skos:definition>

Designed as an early generation 747 replacement, the A340-600 flies 380 passengers in a three-class cabin layout (419 in 2 class) over 7,500 nautical miles (13,900 km). It provides similar passenger capacity to a 747 but with 25% more cargo volume, and at lower trip and seat costs. First flight of the A340-600 was made on 23 April 2001. Virgin Atlantic began commercial services in August 2002.

The A340-600 is more than 10 m longer than a basic -300, making it the longest airliner currently in production; more than four metres longer than the Boeing 747-400. The Airbus A340-600 will continue to hold the record for being the worlds longest commercial aircraft until the first Boeing 747-8 Intercontinental is rolled out in 2010. It is powered by four 56,000 lbf (249 kN) thrust Rolls-Royce Trent 556 turbofans. It also has an additional four-wheel undercarriage on the fuselage center-line to cope with the increased MTOW. Airbus has made provisions for freeing additional upper deck main cabin space, by providing optional arrangements for additional facilities such as crew rest areas, galleys, and lavatories upon the &quot;stretched&quot; A340 aircraft&apos;s lower decks.

text: MIRAI is a conversion of the former nuclear powered ship, MUTSU. The vessel was cut open and its reactor was removed completely in 1995. After non-usable parts and asbestos were also removed and a diesel engine was installed, the vessel was reborn as an oceanographic research vessel MIRAI on August 21, 1996.

MIRAI provides excellent navigational performance and resistance to ice. The vessel can conduct long-term observational studies over wide areas, and is used for oceanographic surveys primarily in the subtropic and subarctic regions of the Arctic, Pacific, and Indian Oceans. It is hoped that MIRAI will perform a role as an advanced international station for ocean-based, marine-Earth research as well as function as a base for transmitting various types of marine and Earth data.

    <skos:definition xml:lang="en">[Text Source: NSSDC, http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1990-005A ] The SPOT-B (Systeme Probatoire d&apos;Observation de la Terre) spacecraft is an earth observation satellite with a ground resolution better than that of the Landsat series satellites. The main applications for the images returned by the second SPOT mission are land-use studies, agriculture and forestry resources, mineral and oil resources, and cartography. The three-axis stabilized satellite operates in a circular sun-synchronous near-polar orbit for a design lifetime of 2 years. The spacecraft dimensions are 2 x 2 x 3.5 m and 15.60 m for the overall length of the deployed solar panel. SPOT-B consists of two parts: (1) the bus, a standard multipurpose platform, and (2) the payload. The bus provides housekeeping information and an onboard computer. The payload is mounted on one of the side panels of the bus. It consists of two identical high-resolution visible (HRV) imaging instruments and a package comprising two magnetic-tape data recorders and a telemetry transmitter. The HRV imaging instrument observes in three spectral bands (in the visible and near infrared regions) with a ground resolution of 20 m, and/or in a broader spectral band (panchromatic black and white) with a ground resolution of 10 m. The pattern of successive ground tracks is repeated exactly at 26-day intervals. The SPOT-B instrument package has the provision for off-nadir viewing which should be particularly useful for monitoring localized phenomena evolving on a relatively short timescale. It also provides the capability for recording stereoscopic pairs of images of a given area during successive satellite passes.Group: Platform_Details   Entry_ID: SPOT-2   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: SPOT      Short_Name: SPOT-2      Long_Name: Systeme Probatoire Pour l&apos;Observation de la Terre-2   End_Group   Group: Synonymous_Platform_Names      Short_Name: SPOT-2      Short_Name: SPOT-B      Short_Name: 20436   End_Group   Group: Platform_Associated_Instruments      Short_Name: DORIS      Short_Name: HRV   End_Group   Group: Orbit      Orbit_Inclination: 98.7°      Period: 100.9 minutes      Perigee: 802 km      Apogee: 831 km      Orbit_Type: LEO &gt; Low Earth Orbit &gt; Polar Sun-Synchronous   End_Group   Creation_Date: 2007-11-13   Online_Resource: http://www.spotimage.fr/web/en/224-technical-information.php   Online_Resource: http://nssdc.gsfc.nasa.gov/nmc/spacecraftOrbit.do?id=1990-005A   Online_Resource: http://www.spot.com/   Sample_Image: http://www.space-risks.com/SpaceData/ImaSat/spot2.jpg   Group: Platform_Logistics      Launch_Date: 1990-01-22      Launch_Site: Kourou, French Guiana      Primary_Sponsor: CNES   End_GroupEnd_Group</skos:definition>

Old Value=he S-3B Viking was built to take off and land on carrier ships, fly into enemy territory and take out threatening submarines. It&apos;s rugged, fast and powerful, but its fighting days are numbered.

Though the United States Navy is slowly decommissioning the fleet, one S-3B is still flying in hostile conditions. Its next mission? Venture into hazardous weather to study a phenomenon that has caused more than 100 commercial aircraft engines to fail, stall or temporarily lose power.

Engineers from NASA&apos;s Glenn Research Center, Boeing and the Navy have combined forces to transform the S-3B into a state-of-the-art NASA research aircraft. Last month, NASA Glenn unveiled the modified plane in Cleveland.

&quot;We were able to capitalize on the decommissioning by acquiring the aircraft directly from the Navy,&quot; explained Dr. Rickey Shyne, director of Glenn&apos;s Facilities and Test Directorate. &quot;This saved taxpayers millions of dollars compared to the cost of a new aircraft.&quot;

Workers at the Navy&apos;s Fleet Readiness Center - Southeast and a Boeing facility in Fla. enhanced the plane by adding commercial satellite communications, global positioning navigation and weather radar systems. They installed research equipment racks in what was once the plane&apos;s bomb bay. And they gave it a shiny blue-and-white NASA paint job.

With these new features, NASA&apos;s S-3B Viking is equipped to conduct science and aeronautics missions, such as environmental monitoring, satellite communications testing and aviation safety research. It can fly up to 40,000 feet high and reach speeds faster than 500 miles per hour, which makes it perfect for studying commercial airline safety issues.

New Value=The S-3B Viking was built to take off and land on carrier ships, fly into enemy territory and take out threatening submarines. It&apos;s rugged, fast and powerful, but its fighting days are numbered.

Though the United States Navy is slowly decommissioning the fleet, one S-3B is still flying in hostile conditions. Its next mission? Venture into hazardous weather to study a phenomenon that has caused more than 100 commercial aircraft engines to fail, stall or temporarily lose power.

Engineers from NASA&apos;s Glenn Research Center, Boeing and the Navy have combined forces to transform the S-3B into a state-of-the-art NASA research aircraft. Last month, NASA Glenn unveiled the modified plane in Cleveland.

The identical twin satellites deliver very-high-resolution optical data products in record time and offer a daily revisit capability to any point on the globe.

The Pléiades constellation is designed to obtain data in double-quick time:

Ability to acquire imagery anywhere in the world in less than 24 hrs. in response to a crisis or natural disaster.
Regular monitoring, as often as every day if required.
Three satellite work plans a day ensure easy handling of last-minute tasking requests.
Twice the coverage and twice the chance of obtaining cloud-free imagery.

Old Value=he Convair 990 Coronado was an enhanced version of the Convair 880. Specifically, it was 10 feet longer, could hold as many as 39 more passengers, and has anti-shock bodies extending back from the trailing edge of the wing (see picture below).

General Dynamics, the parent company of Convair, was the third American aerospace company to enter the jet race behind Boeing with its 707 and Douglas with its DC-9. Being third was a distinct disadvantage as most airlines had already purchased jets before the first Convair ever flew. However, Convair believed it could win with a jet that would be the fastest civilian aircraft in the skies.

These high-altitude aircraft are used as platforms for investigations that cannot be accomplished by sensor platforms of the private sector. Aircraft and spacecraft have proven to be excellent platforms for remote and in situ sensing. The ER-2, flying at the edge of space, can scan shorelines, measure water levels, help fight forest fires, profile the atmosphere, assess flood damage, and sample the stratosphere.[Text and Photo provided by: http://www.nasa.gov/centers/dryden/research/AirSci/ER-2/ ]Group: Platform_Details   Entry_ID: NASA ER-2   Group: Platform_Identification      Platform_Category: Aircraft      Short_Name: NASA ER-2      Long_Name: NASA Earth Resources-2   End_Group   Group: Platform_Associated_Instruments      Short_Name: COSMIR      Short_Name: NAST-MTS      Short_Name: NAST-M      Short_Name: NAST-I   End_Group   Creation_Date: 2008-07-14   Online_Resource: http://www.nasa.gov/centers/dryden/research/AirSci/ER-2/   Online_Resource: http://www.nasa.gov/centers/dryden/news/FactSheets/FS-046-DFRC.html   Sample_Image: http://www.nasa.gov/centers/dryden/images/content/85208main_EC99-45225-2.jpg   Group: Platform_Logistics      Primary_Sponsor: USA/NASA   End_GroupEnd_Group</skos:definition>

text: GOES-8 (GEOSTATIONARY OPERATIONAL ENVIRONMENTAL SATELLITE-8)
language code: en</skos:changeNote>
    <skos:definition xml:lang="en">GOES 8 (GOES-I) was launched on April 13, 1994. On Tuesday April 1,2003 GOES-12 (Formerly Referred to as GOES-M) replaced GOES-8 as theoperational GOES East Satellite. NOAA deactivated the satellite on May5, 2004 and will boost it into an orbit 350 kilometers above itsoriginal geostationary position, where it will be disposed safely inthree controlled burns.GOES I-M represented the next generation of meteorological satellitesand introduces two new features.  The first feature, flexible scan,offers small-scale area imaging that lets meteorologists take picturesof local weather trouble spots. This allows them to improve short-termforecasts over local areas. The second feature, simultaneous andindependent imaging and sounding, is designed to allow weatherforecasters to use multiple measurements of weather phenomena toincrease the accuracy of their forecasts.Each satellite in the series carries two major instruments: an Imagerand a Sounder. These instruments acquire high resolution visible andinfrared data, as well as temperature and moisture profiles of theatmosphere. They continuously transmit these data to ground terminalswhere the data are processed for rebroadcast to primary weatherservices both in the United States and around the world, including theglobal research community.The GOES I-M mission ran from the mid-1990s into thefirst decade of the 21st century.  Each element of the mission hasbeen designed to meet all in-orbit performance requirements for atleast five years.The GOES I-M system performed the following basic functions:+ Acquisition, processing, and dissemination of imaging andsounding data.+ Acquisition and dissemination of Space Environment Monitor(SEM) data.+ Reception and relay of data from ground-based Data CollectionPlatforms (DCPs) that are situated in carefully selected urban andremote areas to the NOAA Command and Data Acquisition (CDA) station.+ Continuous relay of Weather Facsimile (WEFAX) and other data tousers, independent of all other functions.+ Relay of distress signals from people, aircraft, or marine vesselsto the search and rescue ground stations of the Search and RescueSatellite Aided Tracking (SARSAT) system.GOES provides the instantaneous relay functions for the SARSAT system.A dedicated search and rescue transponder on board GOES is designed todetect emergency distress signals originating from Earth-basedsources. These unique identification signals are normally combinedwith signals received by a low-Earth orbiting satellite system andrelayed to a search and rescue ground terminal. The combined data areused to perform effective search and rescue operations.The GOES I-M system serves a region covering the central and easternPacific Ocean; North, Central, and South America; and the central andwestern Atlantic Ocean. Pacific coverage includes Hawaii and the Gulfof Alaska. This is accomplished by two satellites, GOES West locatedat 135 west longitude and GOES East at 75 west longitude. A commonground station, the CDA station located at Wallops, Virginia,supports the interface to both satellites. The NOAA SatelliteOperations Control Center (SOCC), in Suitland, Maryland, providesspacecraft scheduling, health and safety monitoring, and engineeringanalyses.Delivery of products involves ground processing of the raw instrumentdata for radiometric calibration and Earth location information, andretransmission to the satellite for relay to the data user community.The processed data are received at the control center and disseminatedto the National Weather Service&apos;s (NWS) National MeteorologicalCenter, Camp Springs, Maryland, and NWS forecast offices, includingthe National Hurricane Center, Miami, Florida, and the National SevereStorms Forecast Center, Kansas City, Missouri. Processed data are alsoreceived by Department of Defense installations, universities, andnumerous private commercial users.MAIN SPACECRAFT DESIGN ELEMENTSMission life            5 years, minimumDimensions Main body              2 meter (7 foot) cube Deployed length        27 meters (88 feet)Weight                  2100 kg (4600 lb)Orbit                   Geosynchronous Altitude               36,000 km (22,000 mi) Longitude              75W and 135W Latitude               equatorial, within 0.5 degreePower                   1050 watts @ 42 volts, solar array; batterybackupLaunch vehicle          Atlas-I/Centaur (GOES-I/K), Atlas-II/Centaur(GOES-L/M)Communications          Imager and Sounder in GVAR format at 2.1Mbits/secGOES-I/M IMAGERThe GOES Imager is a multi-channel instrument designed to senseradiant and solar-reflected energy from sampled areas of theEarth. The multi-element spectral channels simultaneously sweepeast-west and west-east along a north-to-south path by means of atwo-axis mirror scan system. The instrument can produce full-Earthdisc images, sector images that contain the edges of the Earth, andvarious sizes of area scans completely enclosed within the Earth sceneusing a new flexible scan system. Scan selection permits rapidcontinuous viewing of local areas for monitoring of mesoscale(regional) phenomena and accurate wind determination.IMAGER CHANNELS AND PRODUCTS               CHANNEL  1       2*      3*      4       5*       WAVELENGTH (um)  0.65    3.9     6.7     11      12PRODUCTClouds                  x       x       x       x       xWater Vapor*                            x       x       xSurface Temp.                   o               x       oWinds                   x               x       xAlbedo + IR Flux        x               o       x       oFires + Smoke           x       x               o       oKEY: * = new operational data     x = primary channel     o = secondary channelGOES-I/M SOUNDERThe GOES Sounder is a 19-channel discrete-filter radiometer coveringthe spectral range from the visible channel wavelengths to 15microns. It is designed to provide data from which atmospherictemperature and moisture profiles, surface and cloud-top temperatures,and ozone distribution can be deduced by mathematical analysis. Itoperates independently of and simultaneously with the Imager, using asimilarly flexible scan system. The Sounder&apos;s multi-element detectorarray assemblies simultaneously sample four separate fields oratmospheric columns. A rotating filter wheel, which brings spectralfilters into the optical path of the detector array, provides theinfrared channel definition.PRODUCTS, RESOLUTION AND ACCURACY              RESOLUTION (km)         ACCURACY                Vert.

Old Value=The NOAA Solar Radiation Network is a collection of stations
that provides solar radiations information, specifically, the
amount of energy a user can expect from the Sun.

History:

NOAA and its predecessor agencies, the Environmental Science
Services Administration and the Weather Bureau, have had the
Federal civilian responsibilities for monitoring and documenting
the climate of the United States, including solar radiation and
many other weather elements required by the solar energy
technology user. The solar radiation monitoring network has
existed for about 75 years with varying numbers of stations. In
the 1960&apos;s about 60 NOAA stations and 30 cooperative stations
were reporting solar radiation data to the National Climatic
Center (NCC) in Asheville, N.C. In addition, State, local, and
private organizations were making measurements with varying
degrees of regularity and quality. These non-NOAA networks
continue and, if anything, have increased in number, and with
DOE help some of their data will be archived and published by
the NCC.

Network Centers:

The current network consists of 39 stations of which 35 are in
the contiguous U.S. The remaining are in Alaska, Hawaii, Puerto
Rico, and Guam. All stations are equipped to operate both a
pyranometer and pyrheliometer.

    <skos:definition xml:lang="en">The C-130 Hercules primarily performs the intratheater portion of the airlift mission. The aircraft is capable of operating from rough, dirt strips and is the prime transport for paradropping troops and equipment into hostile areas. Basic and specialized versions perform a diversity of roles, including airlift support, DEW Line and Arctic ice resupply, aeromedical missions, aerial spray missions, fire-fighting duties for the US Forest Service, and natural disaster relief missions. In recent years, they have been used to bring humanitarian relief to many countries, including Haiti, Bosnia, Somalia, and Rwanda.Four decades have elapsed since the Air Force issued its original design specification, yet the remarkable C-130 remains in production. The turbo-prop, high-wing, versatile &apos;Herc&apos; has accumulated over 20 million flight hours. It is the preferred transport aircraft for many US Government services and over 60 foreign countries. The basic airframe has been modified to hundreds of different configurations to meet an ever-changing environment and mission requirement. The C-130 Hercules has unsurpassed versatility, performance, and mission effectiveness. Early C-130A, B, and D versions are now retired.

text: A twin-engine light utility helicopter developed and originally manufactured by Aérospatiale in France. The Écureuil 2 was directly derived from the single-engined AS350 Écureuil, performing its maiden flight on 28 September 1979 and introduced to service shortly thereafter. The type was commonly marketed in North America as the TwinStar. During the 1990s, Aérospatiale merged its helicopter interests into the multinational Eurocopter consortium; under this new entity, the Écureuil 2 continued to be manufactured. Shortly after Eurocopter&apos;s rebranding as Airbus Helicopters, the group decided to discontinue production of the Écureuil 2 during 2016, however, production of its single-engined siblings has continued since then.

Old Value=The University of North Dakota owns and operates a Cessna Citation II aircraft for the purpose of atmospheric research. This aircraft type has a number of design and performance characteristics that make it an ideal platform for a wide range of atmospheric studies. The Citation II is a twin-engine fanjet with an operating ceiling of 43,000 feet (13.1 km). The turbofan engines provide sufficient power to cruise at speeds of up to 340 knots (175 m s-1) or climb at 3300 feet per minute (16.8 m s-1). These high performance capabilities are accompanied by relatively low fuel consumption at all altitudes, giving the Citation an on-station time of 3-5 hours, depending on mission type. Long wings allow it to be operated out of relatively short airstrips and to be flown at the slower speeds (140 kts/72 m s-1) necessary for many types of measurements. The Citation is certified for flight into known icing conditions.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).
Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

    <skos:definition xml:lang="en">In order to expand satellite system capacity after the successful launch of its demonstration satellite, GHGSat started the design of two (2) additional high-resolution satellites in January 2017, called GHGSat-C1 (&apos;Iris&apos;) and GHGSat-C2 (&apos;Hugo&apos;), respectively. GHGSat-C1/-C2 are intended to have similar designs to GHGSat-D, while applying critical lessons learned to improve performance.</skos:definition>

    <skos:definition xml:lang="en">The objectives of TIROS (Television Infrared Observation Satellite)was to test experimental television techniques designed to developa worldwide meteorological satellite information system.The spacecraft was 42 inches in diameter, 19 inches high andweighed 270 pounds. The craft was made of aluminum alloy andstainless steel which was then covered by 9200 solar cells. Thesolar cells served to charge the on-board batteries. Three pairsof solid-propellant spin rockets were mounted on the base plate.Two television cameras were housed in the craft, onelow-resolution and one high-resolution. A magnetic tape recorderfor each camera was supplied for storing photographs while thesatellite was out of range of the ground station network.The antennas consisted of four rods from the base plate to serveas transmitters and one vertical rod from the center of the topplate to serve as a receiver.The craft was spin-stabilized and space-oriented (notEarth-oriented). Therefore, the cameras were only operated whilethey were pointing at the Earth when that portion of the Earthwas in sunlight.The video systems relayed thousands of pictures containingcloud-cover views of the Earth. Early photographs providedinformation concerning the structure of large-scale cloudregimes.For more information, link to&apos;http://www.earth.nasa.gov/history/tiros/tiros1.html&apos;[Summary provided by NASA]Group: Platform_Details   Entry_ID: TIROS   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: TIROS      Short_Name: TIROS      Long_Name: Television Infrared Observation Satellite   End_Group   Group: Synonymous_Platform_Names      Short_Name: TIROS-1   End_Group   Creation_Date: 2007-11-14   Online_Resource: http://www.earth.nasa.gov/history/tiros/tiros1.html   Sample_Image: http://www.nasm.si.edu/exhibitions/lae/images/LE410L8.jpg   Group: Platform_Logistics      Launch_Date: 1960-04-01      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

Old Value=Explorer 32 was an aeronomy satellite which was designed to directly measure temperatures, composition, densities, and pressures in the upper atmosphere on a global basis.  The satellite was a stainless steel, vacuum-sealed sphere, 0.889 m in diameter.  The experimental payload included one ion and two neutral mass spectrometers, three magnetron density gauges, and two electrostatic probes.  Additional equipment included optical and magnetic aspect sensors, magnetic attitude and spin rate control systems, and a tape recorder for data acquisition at locations remote from ground receiving stations.  Power was supplied by silver-zinc batteries and a solar cell array mounted on the satellite exterior.  Two identical pulse-modulated telemetry systems and a canted turnstile antenna were employed.  The two neutral-particle mass spectrometers failed about 6 days after launch. The remaining experiments operated satisfactorily and provided useful data for most of the 10-month satellite lifetime.  The spacecraft ceased to function due to battery failures which resulted from depressurization of the sphere.

    <skos:definition xml:lang="en">The Learjet started life as an abortive Swiss ground-attack fighter aircraft, the FFA P-16. Development started in 1952 and prototypes were ordered the next year. The first prototypes flew in 1955 and construction and testing continued until 1958 when an order for 100 was placed. This was reversed soon after due to a crash of the third prototype. Two additional prototypes were finished, the last in 1960, but the project was ended at this point.The basic structure of this aircraft was seen by Bill Lear and his team as a good starting point to the development of a business jet, which was originally intended to be called the SAAC-23. The wing with its distinctive tip fuel tanks and landing gear of the first Learjets were little changed from those used by the fighter prototypes. The tooling for building the aircraft was purchased and moved to Wichita, Kansas in 1962. On February 7, assembly of the first Learjet began. The next year, the company was renamed the Lear Jet Corporation.[Text provided by: http://en.wikipedia.org/wiki/Learjet ][Photo provided by: http://www.aerospace-technology.com ]Group: Platform_Details   Entry_ID: LEARJET   Group: Platform_Identification      Platform_Category: Aircraft      Short_Name: LEARJET   End_Group   Creation_Date: 2008-07-14   Online_Resource: http://www.learjet.com/   Online_Resource: http://en.wikipedia.org/wiki/Learjet   Sample_Image: http://www.aerospace-technology.com/projects/learjet/images/Learjet45_2.jpgEnd_Group</skos:definition>

text: The Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission will provide rapid-refresh microwave measurements over the tropics that can be used to observe the thermodynamics of the troposphere and precipitation structure for storm systems at the mesoscale and synoptic scale over the entire storm lifecycle. TROPICS comprises a constellation of CubeSats in three low-Earth orbital planes. Each CubeSat will host a high-performance radiometer scanning across the satellite track at 30 RPM to provide temperature profiles using seven channels near the 118.75 GHz oxygen absorption line, water vapor profiles using 3 channels near the 183 GHz water vapor absorption line, imagery in a single channel near 90 GHz for precipitation measurements, and a single channel at 206 GHz for cloud ice measurements. 

This observing system offers an unprecedented combination of horizontal and temporal resolution to measure environmental and inner-core conditions for tropical cyclones (TCs) on a nearly global scale and is a profound leap forward in the temporal resolution of several key parameters needed for detailed study of high-impact meteorological events (TCs being the primary emphasis in this proposal). TROPICS will demonstrate that a constellation approach to earth Science can provide improved resolution, configurable coverage (tropics, near global, or global), flexibility, reliability, and launch access at extremely low cost, thereby serving as a model for future missions.

    <skos:definition xml:lang="en">The Cessna 205, 206, and 207, known variously as the Super Skywagon, Stationair, and Super Skylane are a family of single engine, general aviation aircraft with fixed landing gear used in commercial air service and also for personal use. The family was originally developed from the popular retractable-gear Cessna 210.The line&apos;s combination of a powerful engine, rugged construction and a large cabin has made these aircraft popular bush planes. Cessna describes the 206 as &apos;the sport-utility vehicle of the air.&apos; These airplanes are also used for aerial photography, skydiving and other utility purposes. They can also be equipped with floats, amphibious floats and skis. Alternatively, they can be fitted with luxury appointments for use as a personal air transport.Between the start of production in 1962 and 2006 the total Cessna 205, 206 and 207 production has been 8509 aircraft so far.[Text and Photo provided by: http://en.wikipedia.org/wiki/Cessna_206 ]Group: Platform_Details   Entry_ID: CESSNA 206   Group: Platform_Identification      Platform_Category: Aircraft      Short_Name: CESSNA 206   End_Group   Creation_Date: 2008-07-14   Online_Resource: http://en.wikipedia.org/wiki/Cessna_206   Online_Resource: http://www.cessna.com/   Sample_Image: http://upload.wikimedia.org/wikipedia/commons/thumb/9/91/Cessna.206h.stationair2.arp.jpg/800px-Cessna.206h.stationair2.arp.jpgEnd_Group</skos:definition>

text: Saildrone (https://www.saildrone.com) is a state-of-the-art, wind and solar powered unmanned surface vehicle (USV) capable of long distance deployments lasting up to 12 months.  The drone is autonomous in that it may be guided remotely from land while being completely wind driven. This novel sampling platform is equipped with a suite of instruments and sensors providing high quality, georeferenced, near real-time, multi-parameter surface ocean and atmospheric observations while transiting at typical speeds of 3-5 knots.  Instruments are customizable depending on the mission, but typically include anemometer, barometer, thermosalinograph, CTD, IR pyrometer, fluorometer, and CO2/dissolved oxygen sensors.  Saildrones have additionally been deployed with Acoustic Doppler Current Profilers (ADCP), passive acoustic sensors and echo sounders to measure along-track 3D current velocities and biological acoustic backscatter.  Saildrone adopts a service model approach to the design and implementation of missions and the delivery of data products to customers.  Current deployments include the Tropical and North Pacific, with a focus on future  deployments in the Arctic.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

Old Value=Lockheed&apos;s Electra provided a number of airlines with their introduction to turbine powered aircraft. Today it remains popular with freight operators.

The Lockheed L-188 Electra was developed to meet a 1954 American Airlines requirement for a domestic short to medium range 75 to 100 seat airliner. In June 1955 American awarded Lockheed an order for 35 such aircraft. Lockheed&apos;s design, the L-188, was a low wing, four turboprop powered aircraft. Many other airlines shared American&apos;s interest in the L-188, and by the time the first prototype flew on December 6 1957, the order book stood at 144. Service entry was with Eastern Airlines (due to a pilot&apos;s strike at American) on January 12 1959.

However, any optimism Lockheed felt about a strong sales future would have been short lived, as a number of crashes in 1959 and 1960 (two of which where the aircraft broke up in flight) contributed to a number of order cancellations.

As an interim measure following the crashes, speed restrictions were imposed on Electras. Investigations uncovered a design defect with the engine mountings where the wing would shake and eventually break up. Lockheed undertook a significant modification program where the nacelles, nacelle mountings and wing structure were strengthened, and the speed restrictions were eventually lifted in 1961. After that the Electra proved reliable and popular in service, but the damage had been done and production wound up in 1961 after 170 had been built.

Lockheed built two basic versions of the Electra. The L-188A was the basic production aircraft, and accounted for most Electra sales. The L-188C entered service with KLM in 1959 and had greater fuel capacity and higher weights, and thus improved payload range performance.

The Electra also forms the basis for the hugely successful P-3 Orion long range maritime surveillance aircraft of which more than 600 have been built.

Most Electras currently in service are configured as freighters. From 1967 Lockheed converted 41 Electras to freighters or convertible freighter/passenger aircraft, fitting a strengthened floor and a large cargo door forward of the wing on the left side. Other companies have also converted Electras to freighters. However, a small number remain in passenger service.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

Old Value=NOAA-4 was launched in November 1974 and was one in a series of
reconfigured ITOS satellites launched with new meteorological sensors
onboard to expand the operational capability of the ITOS system.  The
primary objective was to provide global daytime and nighttime direct
readout real-time cloudcover data on a daily basis. The
sun-synchronous spacecraft was also capable of supplying global
atmospheric temperature soundings and very high resolution infrared
cloudcover data for selected areas in either a direct readout or a
tape-recorder mode. A secondary objective was to obtain global
solar-proton flux data on a real-time daily basis. The sensors were
mounted on the satellite baseplate with their optical axes directed
vertically earthward. The nearly cubical spacecraft measured 1 by 1 by
1.2 m. The satellite was equipped with three curved solar panels that
were folded during launch and deployed after orbit was achieved. Each
panel measured over 4.2 m in length when unfolded and was covered with
approximately 3500 solar cells measuring 2 by 2 cm. The dynamics and
attitude control system maintained desired spacecraft orientation
through gyroscopic principles incorporated into the satellite
design. Earth orientation of the satellite body was maintained by
taking advantage of the precession induced from a momentum flywheel so
that the satellite body precession rate of one revolution per orbit
provided the desired &apos;earth-looking&apos; attitude. Minor adjustments in
attitude and orientation were made by means of magnetic coils and by
varying the speed of the momentum flywheel.
The primary sensors consisted of a Very High Resolution Radiometer
(VHRR), Vertical Temperature Profile Radiometer (VTPR), and a Scanning
Radiometer (SR).

Old Value=NOAA-3 was launched in November 1973 and was one in a series of
reconfigured ITOS satellites launched with new meteorological sensors
onboard to expand the operational capability of the ITOS system.  The
primary objective was to provide global daytime and nighttime direct
readout real-time cloudcover data on a daily basis. The
sun-synchronous spacecraft was also capable of supplying global
atmospheric temperature soundings and very high resolution infrared
cloudcover data for selected areas in either a direct readout or a
tape-recorder mode. A secondary objective was to obtain global
solar-proton flux data on a real-time daily basis. The sensors were
mounted on the satellite baseplate with their optical axes directed
vertically earthward. The nearly cubical spacecraft measured 1 by 1 by
1.2 m. The satellite was equipped with three curved solar panels that
were folded during launch and deployed after orbit was achieved. Each
panel measured over 4.2 m in length when unfolded and was covered with
approximately 3500 solar cells measuring 2 by 2 cm. The dynamics and
attitude control system maintained desired spacecraft orientation
through gyroscopic principles incorporated into the satellite
design. Earth orientation of the satellite body was maintained by
taking advantage of the precession induced from a momentum flywheel so
that the satellite body precession rate of one revolution per orbit
provided the desired &apos;earth-looking&apos; attitude. Minor adjustments in
attitude and orientation were made by means of magnetic coils and by
varying the speed of the momentum flywheel.

(VHRR), Vertical Temperature Profile Radiometer (VTPR), and a Scanning

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).
Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

text: The Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission will provide rapid-refresh microwave measurements over the tropics that can be used to observe the thermodynamics of the troposphere and precipitation structure for storm systems at the mesoscale and synoptic scale over the entire storm lifecycle. TROPICS comprises a constellation of CubeSats in three low-Earth orbital planes. Each CubeSat will host a high-performance radiometer scanning across the satellite track at 30 RPM to provide temperature profiles using seven channels near the 118.75 GHz oxygen absorption line, water vapor profiles using 3 channels near the 183 GHz water vapor absorption line, imagery in a single channel near 90 GHz for precipitation measurements, and a single channel at 206 GHz for cloud ice measurements. 

This observing system offers an unprecedented combination of horizontal and temporal resolution to measure environmental and inner-core conditions for tropical cyclones (TCs) on a nearly global scale and is a profound leap forward in the temporal resolution of several key parameters needed for detailed study of high-impact meteorological events (TCs being the primary emphasis in this proposal). TROPICS will demonstrate that a constellation approach to earth Science can provide improved resolution, configurable coverage (tropics, near global, or global), flexibility, reliability, and launch access at extremely low cost, thereby serving as a model for future missions

NASA operates a highly modified Douglas DC-8 jetliner as a flying science laboratory. The aircraft, based at NASA&apos;s Dryden Aircraft Operations Facility in Palmdale, Calif., is used to collect data for experiments in support of projects serving the world&apos;s scientific community. Federal, state, academic and foreign investigators are among those who use NASA’s DC-8.
 
Data gathered with the aircraft at flight altitude and by remote sensing have been used for studies in archaeology, ecology, geography, hydrology, meteorology, oceanography, volcanology, atmospheric chemistry, cryospheric science, soil science and biology. 

Four types of missions are flown with the DC-8: sensor development, satellite sensor verification, space vehicle launch or re-entry telemetry data retrieval and optical tracking, and basic research studies of Earth&apos;s surface and atmosphere.

    <skos:definition xml:lang="en">The Geostationary Meteorological Satellites (GMS) were Japan&apos;s contribution to the international Global Atmospheric Research Program (GARP).  The GMS series carried the Visible and Spin Scan Radiometer (VISSR).  The satellite was spin-stabilized with a despun earth-pointing antenna.  Launched by a Japan N-2 rocket in a August 1981, the satellite was positioned near 140 deg E and was designed to operate for 5 years.  This was a follow-on GMS type spacecraft launched and controlled by NASDA of Japan. The spacecraft was launched in August 1981, and turned off in September 1984.__________Taken from the NSSDC System for Information Retrieval and Storage (SIRS).

Old Value=A Grumman Gulfstream III (G-III) business jet has been modified and instrumented by NASA&apos;s Dryden Flight Research Center to serve as a multi-role cooperative research platform testbed for a variety of flight research experiments. The twin-turbofan aircraft provides long-term capability for efficient testing of subsonic flight experiments for NASA, the U.S. Air Force, other government agencies, academia, and private industry. The aircraft, which carried the military designation of C-20A, was obtained from the U.S. Air Force in 2003.

NASA Dryden&apos;s G-III is equipped with a self-contained on-board Data Collection and Processing System (DCAPS). This embedded instrumentation system allows for automated configuration setups to reduce required engineering support for each mission. It includes primary and backup systems to assure mission reliability, with the backup system available for use concurrently as a slave system when needed. DCAPS is designed to allow easy upgrades, addition of add-on systems for expansion, and to operate in both autonomous and manual modes.

Old Value=The Beechcraft King Air family is part of a line of twin-turboprop aircraft produced by the Beech Aircraft Corporation (now Beechcraft Division of Hawker Beechcraft). The King Air line comprises a number of models that have been divided into two families; the Model 90 and 100 series are known as King Airs, while the Model 200 and 300 series were originally marketed as Super King Airs, with &quot;Super&quot; being dropped by Beechcraft in 1996 (although it is still often used to differentiate the 200 and 300 series King Airs from their smaller stablemates). As of October 2007, the only small King Air in production is the conventional-tail C90GT.

The King Air was the first aircraft in its class and has been in continuous production since 1964. It has outsold all of its turboprop competitors combined and is the only small twin-turboprop business aircraft in production. It now faces competition from jet aircraft such as the Beechcraft Premier I and Cessna Citation Mustang.

The THEMIS probes will line up over North America once every four days. Over the mission’s two-year lifetime, the probes should be able to observe some 30 substorms.THEMIS is the fifth medium-class mission under NASA&apos;s Explorer Program, which was conceived to provide frequent flight opportunities for world-class scientific investigations from space within the Heliophysics and Astrophysics science areas. The Explorers Program Office at Goddard Space Flight Center, Greenbelt, Md., manages this NASA-funded mission. The University of California, Berkeley&apos;s Space Sciences Laboratory and Swales Aerospace, Beltsville, Md., built the THEMIS probes.Group: Platform_Details   Entry_ID: THEMIS   Group: Platform_Identification      Platform_Category: Solar/Space Observation Satellites      Platform_Series_or_Entity: NASA Medium Class Explorers (MIDEX)      Short_Name: THEMIS      Long_Name: Time History of Events and Macroscale Interactions During Substorms   End_Group   Group: Platform_Associated_Instruments      Short_Name: THEMIS-SST      Short_Name: THEMIS-ESA      Short_Name: THEMIS-FGM      Short_Name: THEMIS-EFI      Short_Name: SCM   End_Group   Group: Orbit      Orbit_Type: HEO &gt; Highly Elliptical Orbit   End_Group   Creation_Date: 2008-07-17   Online_Resource: http://www.nasa.gov/mission_pages/themis/main/   Online_Resource: http://themis.ssl.berkeley.edu/   Online_Resource: http://www.atk.com/Customer_Solutions_SpaceSystems/cs_ss_spacesys_ssp_ppcs-themis.asp   Sample_Image: http://www.nasa.gov/images/content/164405main_THEMIS-Spacecraft_bus2.jpg   Group: Platform_Logistics      Launch_Date: 2007-02-17      Launch_Site: Cape Canaveral/Kennedy Space Center, USA      Primary_Sponsor: USA/NASA   End_GroupEnd_Group</skos:definition>

Old Value=The T-39 is the Air Force version of Rockwell&apos;s popular Sabreliner executive aircraft. This handy twin-jet utility plane has been used for many purposes: a four-passenger executive transport, light priority cargo and for radar and navigational training. The T-39 Sabreliner is a low wing, twin jet aircraft. The cockpit and cabin compartments are pressurized and soundproofed for high altitude flight. Power is supplied by two Pratt and Whitney, J60 gas turbine engines located on each side of the aft fuselage. The rated sea level static thrust of each engine is 3,000 pounds at military power.

The T-39 was developed by North American Aviation Inc. as a private venture to meet a USAF requirement for a twin jet utility trainer. The prototype T-39 made its first flight on September 16, 1958. In January 1959, the USAF placed a production order and on June 30, 1960, the first production T-39A made its initial flight. In all, 143 T-39As and 6 T-39Bs were built for the USAF.

Another 62 T-39 variants were produced for the Navy. In July 1961, the Navy ordered ten of North American’s Model NA-277 to train radar operators. In that order the aircraft was designated T3J-1, but by the time the first one was delivered in 1962, the designation had been changed to T-39D. A total of 52 additional aircraft were accepted. After the bulk of military contracts had been met, the Sabreliner entered the commercial market where it became a highly successful executive jet transport.

    <skos:definition xml:lang="en">The Cessna 310/320The sleek Cessna 310 was the first twin engine design from Cessna to enter production after WW2.The 310 first flew on January 3 1953. The modern rakish lines of the new twin were backed up by innovative features such as engine exhaust thrust augmentor tubes and the storage of all fuel in tip tanks. Deliveries commenced in late 1954.The first significant upgrade to the 310 line came with the 310C of 1959, which introduced more powerful 195kW (260hp) IO-470-D engines. The 310D of 1960 featured swept back vertical tail surfaces. An extra cabin window was added with the 310F. A development of the 310F was the turbocharged 320 Skyknight, with TSIO-470-B engines and a fourth cabin side-window. The Skyknight was in production between 1961 and 1969 (the 320D, E and F were named Executive Skyknight), when it was replaced by the similar Turbo 310.The 310G introduced the &apos;stabila-tip&apos; tip tanks, while the 310K replaced the rear two windows on each side with a single unit. Subsequent significant developments include the 310Q and turbocharged T310Q with redesigned rear cabin with a skylight window, and the final 310R and T310R, identifiable for their lengthened noses. Production ended in 1980.USAF military versions were the L-27A (310A) and L-27B (310M) Blue Canoe, later redesignated U-3A and U-3B.

These aircraft remain very busy year round supporting airborne marine mammal, hydrological, remote sensing, air chemistry and emergency response programs. Normal crew size is two pilots with a cabin capable of seating six people with smaller science equipment installed. Known for its stability at slower speeds, the Twin Otter is capable of surveying between 90-140 knots over the ground, making it ideal for missions that require a slower aircraft for data collection.

Old Value=The Lockheed S-3 Viking is a jet aircraft originally used by the United States Navy to identify, track, and destroy enemy submarines. In the late 1990s, the S-3B&apos;s mission focus shifted to surface warfare and aerial refueling. After the retirement of the A-6 Intruder and A-7 Corsair II, the Viking was the only airborne refueling platform organic to the Carrier Air Wing(s) until the fielding of the F/A-18E/F Super Hornet...

One aircraft was transformed into a state-of-the-art NASA research aircraft. The Navy&apos;s Fleet Readiness Center - Southeast and a Boeing facility in Fla. enhanced the plane by adding commercial satellite communications, global positioning navigation and weather radar systems. They installed research equipment racks in what was once the plane&apos;s bomb bay. NASA&apos;s S-3B Viking is equipped to conduct science and aeronautics missions, such as environmental monitoring, satellite communications testing and aviation safety research.

Old Value=The Lockheed S-3 Viking is a jet aircraft originally used by the United States Navy to identify, track, and destroy enemy submarines. In the late 1990s, the S-3B&apos;s mission focus shifted to surface warfare and aerial refueling. After the retirement of the A-6 Intruder and A-7 Corsair II, the Viking was the only airborne refueling platform organic to the Carrier Air Wing(s) until the fielding of the F/A-18E/F Super Hornet...

One aircraft was transformed into a state-of-the-art NASA research aircraft. The Navy&apos;s Fleet Readiness Center - Southeast and a Boeing facility in Fla. enhanced the plane by adding commercial satellite communications, global positioning navigation and weather radar systems. They installed research equipment racks in what was once the plane&apos;s bomb bay. NASA&apos;s S-3B Viking is equipped to conduct science and aeronautics missions, such as environmental monitoring, satellite communications testing and aviation safety research.

    <skos:definition xml:lang="en">The Cessna 188 is a family of light agricultural airplanes produced between 1966 and 1983 by the Cessna Aircraft Company.The various versions of the 188 — the AGwagon, AGpickup, AGtruck and AGhusky, along with the AGcarryall variant of the 185, constituted Cessna&apos;s line of agricultural aircraft.In the early 1960s Cessna decided to expand their already wide line of light aircraft by entering the agricultural aircraft market. They surveyed pilots and operators of other brands of agricultural aircraft to see what features and capabilities these operators were looking for. The resulting aircraft was a conventional single-seat, piston-powered, strut-braced low-winged agricultural airplane.The 188 is the only single-engined Cessna design that does not have a high-wing.The Cessna 188 borrowed heavily from the Cessna 180, the initial version using the same tail cone and fin structure as well as the same Continental O-470-R 230hp (170kW) powerplant. The 188’s airframe is predominantly built from 2024-T3 aluminum, with the chemical hopper constructed from fibreglass. The fuselage is of semi-monocoque construction and is pressurized on later models (using the dynamic pressure resulting from the aircraft&apos;s forward speed) to reduce induction of chemicals into the airframe.The Cessna 188 was first flown on 19 February 1965. The aircraft was certified and entered production in February 1966, with 241 aircraft delivered the first year.The initial design of the Cessna 188 was so successful that over its 17-year production run the basic airframe remained unchanged. Only the engines and the agricultural products dispensing systems were upgraded, other than some minor changes to the ventilation systems.A total of 3967 Cessna 188s of all four variants were built during its production run.[Text and Photo provided by: http://en.wikipedia.org/wiki/Cessna_188 ]Group: Platform_Details   Entry_ID: CESSNA 188   Group: Platform_Identification      Platform_Category: Aircraft      Short_Name: CESSNA 188   End_Group   Creation_Date: 2008-07-14   Online_Resource: http://en.wikipedia.org/wiki/Cessna_188   Online_Resource: http://www.cessna.com/   Sample_Image: http://upload.wikimedia.org/wikipedia/commons/4/4e/CessnaA188BAGtruckC-GSWZ.jpgEnd_Group</skos:definition>

Old Value=The Cessna 172 Skyhawk is a four-seat, single-engine, high-wing airplane.

More Cessna 172s have been built than any other aircraft. It is probably the most popular flight training aircraft in the world.

Measured by its longevity and popularity, the Cessna 172 is the most successful mass produced light aircraft in history. The first production models were delivered in 1956 and they are still in production as of 2008; more than 43,000 have been built.[1] The Skyhawk&apos;s main competitors have been the Beechcraft Musketeer and Grumman AA-5 series (neither in production), the Piper Cherokee and, more recently, the Diamond DA40.

The Cessna 172 started life as a tricycle landing gear upgrade from the taildragger Cessna 170, with a basic level of standard equipment. The first flight of the prototype was in November 1955. The 172 became an overnight sales success and over 1400 were built in 1956, its first full year of production.

Early 172s were similar in appearance to the 170, with the same straight aft fuselage and tall gear legs, although the 172 had a straight vertical tail while the 170 had a rounded fin and rudder. Later 172 versions incorporated revised landing gear and the sweptback tail which is still in use today.The final aesthetic development in the mid-1960s, was a lowered rear deck that allowed an aft window. Cessna advertised this added rear visibility as &quot;Omni-Vision&quot; . This airframe configuration has remained almost unchanged since then, except for updates in avionics and engines, including the Garmin G1000 glass cockpit in 2005. Production had been halted in the mid-1980s, but was resumed in 1996 with the 160 hp (120 kW) Cessna 172R Skyhawk and was supplemented in 1998 by the 180 hp (135 kW) Cessna 172S Skyhawk SP.

The  geodetic  instrumentation  systems  included  (1)  four optical beacons, (2) two  C-band  radar  transponders,  (3)  a  passive  radar  reflector, (4) a  sequential  collation  of range radio range transponder, (5) a Goddard  range  and  range  rate  transponder,  (6)  laser  reflectors, and (7)  Doppler beacons.  Non-geodetic systems included a laser detector and a  Minitrack  interferometer  beacon.   The  objectives of the spacecraft  were  to  optimize  optical  station visibility periods and to provide  complementary  data for inclination-dependent terms established by the  Explorer  29  (GEOS 1) gravimetric studies.  The spacecraft was placed  into  a  retrograde orbit to accomplish these objectives.  Operational  problems  occurred  in  the  main  power  system, optical beacon flash  system,  and  the  spacecraft  clock,  and  adjustments  in scheduling  resulted in nominal operations.Auxiliary Information  Launch Date and Time : 1968-01-11 16:19:00  Epoch Date and Time :  1977-02-28  Orbit Type :  Geocentric  Apogee(km) :    1570.

text: The NASA Goddard Space Flight Center’s (GSFC) Wallops Flight Facility (WFF) Aircraft Office operates the NASA C-23 Sherpa research aircraft available to support airborne science research. The C-23 is used to perform scientific research, provide logistics support on an as-needed basis to other airborne science missions, and can be used as a technology test bed for new airborne and satellite instrumentation. This aircraft is also available to support range surveillance and recovery operations as needed. The C-23 is a self-sufficient aircraft that can operate from short field civilian and military airports to remote areas of the world in support of scientific studies and other operations.

text: ESSA-3 satellite replaced ESSA-1. It provided cloud-cover photography to the US&apos;s National Meteorological Center for the purpose of preparing weather analyses and forecasts. The spacecraft was designed and configured exactly the same as NIMBUS-1. The total weight of the spacecraft was 912 pounds.

The spacecraft was an 18-sided polygon, 42 inches in diameter, 22 inches high and weighed 320 pounds; it was made of aluminum alloy and stainless steel, then covered with 9100 solar cells. The solar cells served to charge the 63 nickel-cadmium batteries.
The two cameras were mounted 180-degrees opposite each other along the side of the cylindrical craft. The &quot;cartwheel&quot; configuration of the TIROS-9 was selected as the orbital configuration for the ESSA satellites. Therefore, a camera could be pointed at some point on Earth every time the satellite rotated along its axis. The spacecraft operating system was the same as on the TIROS-9. The craft was placed in its planned Sun-synchronous 101 degree inclination retrograde orbit. The ESSA-3 system transmitted images covering 2000-square mile areas with 2-mile resolution from every location once per day.

ESSA-3 Stats:

Launch Date:  October 02, 1966
Operational Period: 736 days until deactivated by NASA on December 02, 1968
Launch Vehicle: Thrust Augmented Three-Stage Delta
Launch Site: Vandenberg Air Force Base, CA
Type:    Weather Satellite

    <skos:definition xml:lang="en">In April 1958 Lockheed corporation won a US Navy competition to find a replacement for the Navy&apos;s aging P2V Neptune series of long range antisubmarine warfare and maritime patrol aircraft. Lockheed&apos;s winning proposal was designated &apos;P3V Orion&apos;. Named for the winter constellation of the mighty hunter, the Orion was actually derived from the famous Lockheed Electra civil airliner.

text: The P-3C Orion is a four-engine turboprop aircraft originally designed by the U.S. Navy to locate and track enemy submarines. The mission has been modified in recent years to provide on-station surface surveillance for both land and sea missions. The P-3C has advanced submarine detection sensors such as directional frequency and ranging (DIFAR) sonobuoys and magnetic anomaly detection (MAD) equipment. The avionics system is integrated by a general-purpose digital computer that supports all the tactical displays, monitors and automatically launches ordnance and provides flight information to the pilots. In addition, the system coordinates navigation information and accepts sensor data inputs for tactical display and storage. The P-3C can carry a mixed payload of weapons internally and on wing pylons.

    <skos:definition xml:lang="en">Spacecraft Brief Description  The  GEOS  1  (Geodetic  Earth  Orbiting  Satellite)  spacecraft was a  gravity-gradient-stabilized,    solar-cell   powered   unit   designed  exclusively  for geodetic studies.  It was the first successful active  spacecraft    of    the    National    Geodetic   Satellite   Program.  Instrumentation   included   (1)   four  optical  beacons,  (2)  laser  reflectors,  (3)  a  radio range transponder, (4) Doppler beacons, and  (5)  a  range  and  range  rate  transponder.   These were designed to  operate   simultaneously   to   fulfill  the  objectives  of  locating  observation  points (geodetic control stations) in a three dimensional  earth  center-of-mass  coordinate  system  within 10 m of accuracy, of  defining  the  structure  of the earth&apos;s irregular gravitational field  and  refining  the  locations  and  magnitudes  of  the  large gravity  anomalies, and of comparing results of the various systems onboard the  spacecraft  to  determine  the  most  accurate  and  reliable  system.  Acquisition  and recording of data were the responsibility of the GSFC  Space  Tracking  and  Data  Acquisitions  Network (STADAN).  Ten major  observing networks were used.Auxiliary Information  Launch Date and Time : 1965-11-06 18:43:00  Epoch Date and Time :  1978-12-30  Orbit Type :  Geocentric  Apogee(km) :    2275.

    <skos:definition xml:lang="en">The Beechcraft Super King Air family is part of a line of twin-turboprop aircraft produced by the Beech Aircraft Corporation (now the Beechcraft Division of Hawker Beechcraft). The King Air line comprises a number of model series that fall into two families: the Model 90 series, Model 100 series (these models comprising the King Air family), Model 200 series and Model 300 series. The latter two models were originally marketed as the &apos;Super King Air&apos; family, but the &apos;Super&apos; was dropped in 1996.</skos:definition>

text: The ESSA-5 satellite replaced ESSA-3 and provided cloud-cover photography to the US&apos;s National Meteorological Center for the purpose of preparing weather analyses and forecasts. The spacecraft was an 18-sided polygon, 42 inches in diameter, 22 inches high and weighed 320 pounds; it was made of aluminum alloy and stainless steel then covered with 9100 solar cells, used to charge the 63 nickel-cadmium batteries.

The two cameras were mounted 180 degrees opposite each other along the side of the cylindrical craft. The &quot;cartwheel&quot; configuration of the TIROS-9 was selected as the orbital configuration for the ESSA satellites. Therefore, a camera could be pointed at some point on Earth every time the satellite rotated along its axis. The spacecraft operating system was the same as on the TIROS-9. The craft was placed in its planned Sun-synchronous 102-degree inclination retrograde orbit. The ESSA-5 system transmitted images covering 2000-square mile areas with 2-mile resolution from every location once per day.

Therefore, a camera could be pointed at some point on Earth every time the satellite rotated along its axis. The spacecraft operating system was the same as on the TIROS-9. The craft was placed in its planned Sun-synchronous 102-degree inclination retrograde orbit. The ESSA-5 system transmitted images covering 2000-square mile areas with 2-mile resolution from every location once per day.ESSA-5 Stats:Launch Date:  April 20, 1967Operational Period:   738 days until deactivated by NASA on February 20, 1970Launch Vehicle:   Thrust Augmented Three-Stage DeltaLaunch Site:   Vandenberg Air Force Base, CAType:  Weather Satellite</skos:definition>

Old Value=The PA-31 Navajo is a family of cabin-class, twin-engine aircraft designed and built by Piper Aircraft using Lycoming engines for the general aviation market.

In the mid-1960s, an aircraft of this size was sorely needed and founder William T. Piper requested the type be developed. Targeted at small-scale cargo and feeder liner operations and the corporate market, the aircraft was a success. It continues to prove a popular choice, but due to greatly decreased demand across the general aviation sector in the 1980s, production of the PA-31 ceased.

Old Value=The DeHavilland Twin Otter (DHC-6) is a highly maneuverable, versatile aircraft which can be flown slowly (80-160 knots/150-300 km/hr) and in tight circles. The Twin Otter is a high-winged, unpressurized, twin-engine turboprop aircraft equipped with color weather radar, radar altimeter, dual GPS/Loran-C navigation systems with scientific data drops, and camera ports in the nose and belly areas. A standard flight crew consists of two NOAA pilots. In support of NOAA or NOAA-related missions, this platform has conducted low-level slow speed aerial surveys of marine mammals, aerial video surveys of coastal erosion, various remote sensing missions, atmospheric air chemistry sampling, and atmospheric eddy flux and concentration gradient assessments.

Old Value=The HC-130 is an extended-range, combat rescue version of the C-130 transport aircraft. Capable of independent employment in the no-to-low threat environment. Its primary mission is to provide air refueling for rescue helicopters. The HC-130 can perform extended searches in a permissive environment and has the capability to airdrop pararescuemen and survival equipment to isolated survivors when a delay in the arrival of a recovery vehicle is anticipated. Flights to air refueling areas or drop zones are accomplished at tactical low altitude to avoid threats. NVG-assisted, low-altitude air refueling and other operations in a low-threat environment are performed by specially trained crews. The crew can perform airborne mission commander (AMC) duties in a no-to-low threat environment when threat conditions permit.

text: The first proposal to use satellites for navigation was made by V.S.Shebashevich in 1957. This idea was born during the investigation of the possible application of radio-astronomy technologies for aeronavigation. Further investigations were conducted in a number of the Soviet institutions to increase the accuracy of navigation definitions, global support, daily application and independence from weather conditions. The research results were used in 1963 for R&amp;D project on the first Soviet low-orbit “Cicada” system. In 1967 the first navigation Soviet satellite &quot;Cosmos-192&quot; was launched. The navigation satellite provided continuous radio navigation signal transmission on 150 and 400 MHz during its active lifetime.

The “Cicada” system of four satellites was commissioned in 1979. The navigation satellites were placed into circular orbits 1,000 km high with an inclination of 83 ° and equal distribution of orbital planes to the equator. It allowed users to acquire one of the satellites every hour and a half or two and fix the position within 5-6 min of a navigation session. The navigation system “Cicada” used one-way user-to-satellite range measurements. Along with improvement of the satellite onboard systems and navigation equipment much attention was given to enhancing accuracy of determining and predicting parameters of the navigation satellite orbits.

Later, receiving measuring equipment was disposed on the “Cicada” satellites to detect distress radiobeacons. The satellites received these signals and rebroadcast them to special ground stations where the computation of the exact coordinates of the emergency objects (ships, aircraft, etc.) was held. The “Cicada” satellites tracking distress radiobecons formed “Cospas” system that together with the US-French-Canadian &quot;Sarsat&quot; system built an integrated search and rescue service that saved several thousands of lives. The “Cicada” space navigation system (and its “Cicada-M” modernization) was designed for navigation support of military users and had been in use since 1976. In 2008 “Cicada” and “Cicada-M” users started to use GLONASS system and the operation of those systems was halted. It was impossible for the low-orbit systems to meet requirements of a great number of users.

Successful operation of the low-orbit satellite navigation systems by the marine users attracted widespread attention to satellite navigation. A general-purpose navigation system was needed to meet the requirements of the great majority of prospective users.

Based on the all-round research it was decided to choose the orbital constellation consisting of 24 satellites equally distributed in three orbital planes inclined at 64.8° to the equator. The GLONASS satellites are placed in roughly circular orbits with the nominal orbit altitude 19,100 km and an orbital period of 11 hours, 15 minutes, 44 seconds. Due to the period value it became possible to create a sustainable orbital system that unlike GPS does not require supporting correcting pulses during its active lifetime. The nominal inclination ensures global availability on the territory of the Russian Federation even when several SVs are not operational.

Two challenges have been faced for designing a high-orbit navigation system. The first one dealt with mutual synchronized satellite timescales with the accuracy of billionths of a second (nanoseconds). It became possible because of high-orbit onboard caesium frequency standards with nominal stability at 10-13 and ground hydrogen frequency standard with nominal stability at 10-14 and also because of ground facilities of time scale comparison with error of 3-5 ns. The second challenge addressed high-precision determination and prediction of navigation satellite orbit parameters. This issue was solved with scientific research on second order factors of infinitesimals, such as light pressure, irregularities of the Earth rotation and polar motions and etc.

Flight tests of the Russian high orbit satellite navigation system, called GLONASS, were started in October, 1982 with the launch of “Kosmos-1413” satellite. The GLONASS system was formally declared operational in 1993. In 1995 it was brought to a fully operational constellation (24 GLONASS satellites of the first generation). A great drawback that should have been focused on consisted in the lack of civil navigation equipment and civil users.

Reduction in funding for space industry in 1990 led to degradation of the GLONASS constellation. In 2002 the GLONASS constellation consisted of 7 satellites that was insufficient for navigation support of the Russian territory even with limited availability. GLONASS was behind GPS in accuracy characteristics, SVs active lifetime comprised 3-4 years.

text: TET-1 (Technologie Erprobungs Träger-1) is a German technology demonstration microsatellite of DLR (German Aerospace Center) within its OOV (On-Orbit Verification) program. Project funding is provided by the German Ministry for Economics and Technology (Bundesministerium für Wirtschaft und Technologie). The overall objective is to provide industry and research institutes with adequate means for the in-flight validation of space technology. Certain programmatic rules were established for the space segment and the ground segment to realize TET-1 as a low-cost mission within a relatively short timeframe under the leadership of an industrial space company as prime contractor.

Flight opportunities for technology demonstration and verification should ideally be provided on a regular basis in a cost efficient and safe manner. A market survey of German industries&apos; and institutes&apos; technologies has shown that about 75% of the experiments can be verified using a microsatellite.

The OOV-Program is thus structured into two main parts with respect to the flight opportunities offered. The first comprises the microsatellites TET with a planned flight opportunity every two years. For payloads which do not fit on TET microsatellite concept, DLR will cooperate with national and international partners to provide flight opportunities on other carriers.

    <skos:definition xml:lang="en">[Source: National Space Science Data Center (NSSDC), http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1991-032A ]NOAA-12 (NOAA-D before launch) is a third-generation operational meteorological satellite for use in the National Environmental Satellite, Data, and Information Service (NESDIS). The satellite design provides an economical and stable sun-synchronous (morning equator-crossing) platform for advanced operational instruments to measure the earth&apos;s atmosphere, its surface and cloud cover, and the near-space environment. Primary sensors include an Advanced Very High Resolution Radiometer (AVHRR) for observing daytime and nighttime global radiances and temperatures and a TIROS Operational Vertical Sounder (TOVS) for obtaining temperature and water vapor profiles through the earth&apos;s atmosphere. Secondary experiments consist of a Space Environment Monitor (SEM), which measures the proton and electron fluxes near the earth, and an ARGOS Data Collection and Location System, which processes and relays to central data acquisition stations the various meteorological data received from free-floating balloons and ocean buoys distributed around the globe. The satellite is based upon the Block 5D spacecraft bus developed for the U.S. Air Force, and it is capable of maintaining an earth-pointing accuracy of better than plus or minus 0.1 deg with a motion rate of less than 0.035 deg/s.

text: [Update 2011-12-13: GOES-15 replaced GOES-11 as the GOES-West operational spacecraft on 2011-12-06]
The Geostationary Operational Environmental Satellite (GOES)-P represents a continuation of the newest generation of environmental satellites built by Boeing for the National Oceanic and Atmospheric Administration (NOAA) under the technical guidance and project management of NASA&apos;s Goddard Space Flight Center, Greenbelt, Md. GOES satellites provide the familiar weather pictures seen on United States television newscasts every day. The GOES imaging and sounding instruments (built by ITT) feature flexible scans for small-scale area viewing in regions of the visible and infrared spectrum allowing meteorologists to improve short-term forecasts. GOES provides nearly continuous imaging and sounding, which allow forecasters to better measure changes in atmospheric temperature and moisture distributions and hence increase the accuracy of their forecasts. GOES environmental information is used for a host of applications, including weather monitoring and prediction models, ocean temperatures and moisture locations, climate studies, cryosphere (ice, snow, glaciers) detection and extent, land temperatures and crop conditions, and hazards detection. The GOES-O&amp;P Imagers have improved resolution in the 13 micrometer channel from 8 km to 4 km. The finer spatial resolution allows an improved cloud-top product, height of atmospheric motion vectors and volcanic ash detection. GOES-P continues the improved image navigation and registration, additional power and fuel lifetime capability, space weather, solar x-ray imaging, search and rescue, and communication services as provided on GOES-13. GOES-P Launches! The GOES-P satellite launched at 6:57 p.m. EST March 4 aboard a United Launch Alliance Delta IV rocket from Launch Complex 37B at Cape Canaveral Air Force Station in Florida. GOES-P is the third and final spacecraft to be launched in the GOES-N series of geostationary environmental weather satellites.

Small robotic aircraft for long-range environmental monitoring
and surveillance.  It has been developed especially for
meteorological and environmental reconnaissance over oceanic and
remote areas and in harsh conditions, for which its economy and
flexibility will allow routine operations on a much wider scale
than has been possible in the past. It has been extended to
surveillance and other reconnaissance applications.

The Aerosonde is being deployed to fill chronic gaps in the
global upper-air sounding network, to conduct systematic
surveillance of tropical cyclones and other severe weather, to
undertake offshore surveillance and agricultural/biological
surveys, and to obtain specialist observations, such as volcanic
plumes.

Miniaturisation and flexibility, fully robotic operation and

    <skos:definition xml:lang="en">[Source: NASA NSSDC, http://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1997-019A ]The Geostationary Operational Environmental Satellite GOES 10 is the third satellite in a series of next generation geosynchronous spacecraft, referred to as GOES-NEXT and represented by the GOES I through GOES M spacecraft. The GOES-NEXT series is a joint effort on the part of NASA and NOAA to provide continued operational monitoring of weather systems primarily over the United States, distribute meteorological data to regional and national weather offices within the USA, contribute to the development of an environmental data collection network, contribute to the search and rescue program, improve the capability for forcasting and provide real-time warnings of solar distrubances, and to extend knowledge and understanding of atmospheric processes to improve short and long-term weather forecasts.The GOES-NEXT series extends the capabilities of the previous GOES 1-7 spacecraft. The GOES I-M spacecraft will be placed over the equator at 135 deg West or 75 deg West. The design allows unobstructed views of the Earth for operational coverage by the spacecraft sensors. The spacecraft configuration is a compact box-shaped main body that carries the Earth-observing instruments, a continuous-drive solar array attached to the south panel through a yoke assembly, and a solar pointing instrument gimbal mounted on the solar panel yoke. The main body accomodates the sensors, electronics, and support subsystems. The communication antennas, except the Tracking, Telemetry, and Command (TT&amp;C) antenna, are hard-mounted to the Earth-facing panel. The Propulsion Module consists of the fuel and oxidizer tanks for the bipropellant propulsion subsystem mounted on the central cylinder. The Attitude and Orbit Control Substem (AOCS) provides attitude control of the spacecraft. The AOCS consists of the sensors, electronics, and the actuators. The GOES power is generated from the solar array and two 12 A-hr batteries. Power is automatically regulated during solar eclipses. A conical shaped solar sail at the end of a 58-foot boom balances torque caused by solar radiation. The main body of the spacecraft is a 2-meter cube. In its deployed orbit configuration, the overall length is about 27 meters. Initial mass was about 4640 pounds, including fuel. Design lifetime is about five years.The Image Navigation/Registration (INR) system provides Imager and Sounder data products in real-time to users. The Communications, Command, and Data Handling subsystem is comprised of antennas, receivers, transponders, transmitters, data encoders and encryptors and multiplexers. The Tracking Telemetry and Command (TT&amp;C) subsystem provides the necessary monitor and command link between the spacecraft and the ground stations.The GOES-NEXT instruments consist of the following: (1) Earth Imaging System, a 5-channel visible and infrared radiometer which provides Earth imagery 24 hours a day; (2) Sounding System, a 19-channel discrete-filter radiometer for obtaining atmospheric temperature and moisture soundings; (3) a Space Environment Monitor (SEM), which consists of a magnetic field sensor, a solar X-ray sensor, an energetic particle sensor (EPS), and a High Energy Proton and Alpha Detector (HEPAD); (4) a Search and Rescue subsystem (SARSAT), which receives signals from 406 MHz distress beacons and relays them to the ground; (5) a Data Collection System (DCS) for collecting and relaying real-time information from Data Collection Platforms (DCPs) such as buoys, balloons, remote weather stations, ships, and aircraft; and (6) a Weather Facsimile (WEFAX) system which relays processed weather imagary from the Wallops Island station to the user community.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

text: GOES (NOAA GEOSTATIONARY OPERATIONAL ENVIRONMENTAL SATELLITES)
language code: en</skos:changeNote>
    <skos:definition xml:lang="en">GOES satellites provide the kind of continuous monitoring necessaryfor intensive data analysis. They circle the Earth in a geosynchronousorbit, which means they orbit the equatorial plane of the Earth at aspeed matching the Earth&apos;s rotation. This allows them to hovercontinuously over one position on the surface. The geosynchronousplane is about 35,800 km (22,300 miles) above the Earth, high enoughto allow the satellites a full-disc view of the Earth. Because theystay above a fixed spot on the surface, they provide a constant vigilfor the atmospheric &apos;triggers&apos; for severe weather conditions such astornadoes, flash floods, hail storms, and hurricanes. When theseconditions develop the GOES satellites are able to monitor stormdevelopment and track their movements.GOES satellite imagery is also used to estimate rainfall during thethunderstorms and hurricanes for flash flood warnings, as well asestimates snowfall accumulations and overall extent of snowcover. Such data help meteorologists issue winter storm warnings andspring snow melt advisories. Satellite sensors also detect ice fieldsand map the movements of sea and lake ice.NASA launched the first GOES for NOAA in 1975 and followed it withanother in 1977. Currently, the United States is operating GOES-10 andGOES-12. (GOES-9, which is partially operational, is being provided tothe Japanese Meteorological Agency to replace their failinggeostationary satellite.) GOES-11 is being stored in orbit as areplacement for GOES-12 or GOES-10 in the event of failure.Additional Information on GOES Satellites:&apos;http://www.oso.noaa.gov/goes/&apos;To view a 3D orbit of GOES satellites, observe the J Tracksatellite tracking web page at:&apos;http://liftoff.msfc.nasa.gov/realtime/jtrack/&apos;[Summary Extracted from the NOAA Office of Satellite Operations Home Page]Group: Platform_Details   Entry_ID: GOES   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: GOES (Geostationary Operational Environmental Satellite)      Short_Name: GOES      Long_Name: NOAA Geostationary Operational Environmental Satellites   End_Group   Group: Synonymous_Platform_Names      Short_Name: GOES-1      Short_Name: GOES-2      Short_Name: GOES-3      Short_Name: GOES-4      Short_Name: GOES-5      Short_Name: GOES-6      Short_Name: GOES-7      Short_Name: GOES-8      Short_Name: GOES-9      Short_Name: GOES-10      Short_Name: GOES-11      Short_Name: GOES-12      Short_Name: GOES-13      Short_Name: GOES-N   End_Group   Group: Platform_Associated_Instruments      Short_Name: SEM      Short_Name: SAR      Short_Name: HEPAD      Short_Name: MAGNETOMETERS      Short_Name: VAS      Short_Name: VISSR      Short_Name: GOES I-M SOUNDER      Short_Name: GOES I-M IMAGER      Short_Name: SXI   End_Group   Group: Orbit      Orbit_Altitude: 35,800 km (22,300 miles)      Orbit_Inclination: 0.41 degrees      Period: 1,436 minutes      Repeat_Cycle: GOES flies in an orbit above the equator at the same rate as the equator turns -- one cycle per day.

    <skos:definition xml:lang="en">Nimbus-4 was launched in April 1970 and was the fourth in a series ofsecond-generation meteorological research-and-development satellites that wasdesigned to serve as a stabilized, earth-oriented platform for the testing ofadvanced meteorological sensor systems and for collecting meteorological data.The polar-orbiting spacecraft consisted of three major structures: (1) aring-shaped sensor mount, (2) solar paddles, and (3) the control systemhousing. The solar paddles and the control system were connected to the sensormount by a truss structure, giving the satellite the appearance of an oceanbuoy. Nimbus-4 was nearly 3.7 m tall, 1.45 m in diameter at the base, and about3 m across with solar paddles extended. The torus-shaped sensor mount, whichformed the satellite base, housed the electronics equipment and batterymodules. The lower surface of the torus ring provided mounting space forsensors and telemetry antennas. An H-frame structure mounted within the centerof the torus provided support for the larger experiments and tape recorders.Mounted on the control system housing, which was on top of the spacecraft, weresun sensors, horizon scanners, gas nozzles for attitude control, and a commandantenna. Use of an advanced attitude-control subsystem permitted thespacecraft&apos;s orientation to be controlled to within plus or minus 1 degree forall three axes (pitch, roll, and yaw).Primary experiments consisted of an image dissector camera system for providingdaytime cloudcover pictures both in real-time and recorded modes,temperature-humidity infrared radiometer (THIR) for measuring daytime andnighttime surface and cloudtop temperatures as well as the water vapor contentof the upper atmosphere, infrared interferometer spectrometer (IRIS) formeasuring the emission spectra of the earth/atmosphere system, satelliteinfrared spectrometer (SIRS) for determining the vertical profiles oftemperature and water vapor in the atmosphere, a monitor of ultraviolet solarenergy (MUSE) for detecting solar UV radiation, a backscatter ultraviolet (BUV)detector for monitoring the vertical distribution and total amount ofatmospheric ozone on a global scale, a filter wedge spectrometer (FWS) foraccurate measurement of IR radiance as a function of wavelength from theearth/atmosphere system, a selective chopper radiometer (SCR) for determiningthe temperatures of six successive 10-km layers in the atmosphere fromabsorption measurements in the 15-micrometer CO2 band, and an interrogation,recording, and location system (IRLS) for locating, interrogating, recording,and retransmitting meteorological and geophysical data from remote collectionstations. The spacecraft performed well until April 14, 1971, when attitudeproblems started. The experiments then operated on a limited time basis untilSeptember 30, 1980.__________Taken from the NSSDC System for Information Retrieval and Storage (SIRS).

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

    <skos:definition xml:lang="en">The primary objectives of Ulysses, formerly the International Solar Polar Mission (ISPM), are to investigate, as a function of solar latitude, the properties of the solar wind and the interplanetary magnetic field, of galactic cosmic rays and neutral interstellar gas, and to study energetic particle composition and acceleration. The 55 kg payload includes two magnetometers, two solar wind plasma instruments, a unified radio/plasma wave instrument, three energetic charged particle instruments, an interstellar neutral gas sensor, a solar X-ray/cosmic gamma-ray burst detector, and a cosmic dust sensor. The communications systems is also used to study the solar corona and to search for gravitational waves. Secondary objectives included interplanetary and planetary physics investigations during the initial Earth-Jupiter phase and investigations in the Jovian magnetosphere. The spacecraft used a Jupiter swingby in Feb. 1992 to transfer to a heliospheric orbit with high heliocentric inclination, and will pass over the rotational south pole of the sun in mid-1994 at 2 AU, and over the north pole in mid-1995. A second solar orbit will take Ulysses again over the south and north poles in years 2000 and 2001, respectively. The spacecraft is powered by a single radio-isotope generator. It is spin stabilized at a rate of 5 rpm and its high-gain antenna points continuously to the earth.

text: GOES 2 was a NASA-developed, NOAA-operated, geosynchronous, and operational spacecraft. The spin-stabilized spacecraft carried (1) a visible infrared spin-scan radiometer (VISSR) to provide high-quality day/night cloudcover data and to take radiance-derived temperatures of the earth/atmosphere system, (2) a meteorological data collection and transmission system to relay processed data from central weather facilities to APT-equipped regional stations and to collect and retransmit data from remotely located earth-based platforms, and (3) a space environment monitor (SEM) system to measure proton, electron, and solar X-ray fluxes and magnetic fields. The cylindrically shaped spacecraft measured 190.5 cm in diameter and 230 cm in length, exclusive of a magnetometer that extended an additional 83 cm beyond the cylinder shell. The primary structural members were a honeycombed equipment shelf and thrust tube. The VISSR telescope was mounted on the equipment shelf and viewed the earth through a special aperture in the side of the spacecraft. A support structure extended radially out from the thrust tube and was affixed to the solar panels, which formed the outer walls of the spacecraft and provided the primary source of electrical power. Located in the annulus-shaped space between the thrust tube and the solar panels were stationkeeping and dynamics control equipment, batteries, and most of the SEM equipment. Proper spacecraft attitude and spin rate (approximately 100 rpm) were maintained by two separate sets of jet thrusters mounted around the spacecraft equator and activated by ground command. The spacecraft used both UHF-band and S-band frequencies in its telemetry and command subsystem. A low-power VHF transponder provided telemetry and command during launch and then served as a backup for the primary subsystem once the spacecraft attained synchronous orbit. For more detailed information, see &quot;The GOES/SMS User&apos;s Guide&quot; (TRF B28599), available from NSSDC.

Old Value=The Advanced Land Observing Satellite-2 (ALOS-2) is follow-on mission from the &quot;DAICHI&quot;, which contributed to cartography, regional observation, disaster monitoring, and resource surveys. ALOS-2 will succeed this mission with enhanced capabilities.
Specifically, JAXA is conducting research and development activities to improve wide and high-resolution observation technologies developed for DAICHI in order to further fulfill social needs.
These social needs include: 1) Disaster monitoring of damage areas, both in cosiderable detail, and when these areas may be large 2) Continuous updating of data archives related to national land and infrastructure information 3) Effective monitoring of cultivated areas 4) Global monitoring of tropical rain forests to identify carbon sinks.
The state-of-the-art L-band Synthetic Aperture Radar (SAR) aboard ALOS-2, which is an active microwave radar using the 1.2GHz frequency range, will, in responding to society&apos;s needs, have enhanced performance compared to DAICHI/PALSAR. The SAR is capable of observing day and night, and in all weather conditions.

text: GOES 7 was launched in February 1987 and was a NASA-developed, NOAA-operated, geosynchronous, and operational spacecraft.  The cylindrically shaped spacecraft measured 190.5 cm in diameter and 230 cm in length, exclusive of a magnetometer that extended an additional 83 cm beyond the cylinder shell. The primary structural members were a honeycombed equipment shelf and thrust tube.  The VISSR telescope was mounted on the equipment shelf and viewed the Earth through a special aperture in the side of the spacecraft.  A support structure extended radially out from the thrust tube and was affixed to the solar panels, which formed the outer walls of the spacecraft and provided the primary source of electrical power.  Located in the annulus-shaped space between the thrust tube and the solar panels were stationkeeping and dynamics control equipment, batteries, and most of the SEM equipment.  Proper spacecraft attitude and spin rate (approximately 100 rpm) were maintained by two separate sets of jet thrusters mounted around the spacecraft equator and activated by ground command.  The spacecraft used both UHF-band and S-band frequencies in its telemetry and command subsystem.  A low-power VHF transponder provided telemetry and command during launch and then served as a backup for the primary subsystem once the spacecraft attained orbit.  The spin-stabilized spacecraft carried a visible infrared spin-scan radiometer atmospheric sounder, meteorological data collection and transmission system, space environment monitor, energetic particle monitor, and a magnetic field monitor.  GOES 7 was positioned at 98 degrees West in the summer (Atlantic hurricane season) and 108 degrees West in the winter (Pacific storm season).

The spacecraft used both UHF-band and S-band frequencies in its telemetry and command subsystem. A low-power VHF transponder provided telemetry and command during launch and then served as a backup for the primary subsystem once the spacecraft attained orbit. The spin-stabilized spacecraft carried a visible infrared spin-scan radiometer, meteorological data collection and transmission system, space environment monitor, and a biaxial fluxgate magnetometer. It operated at 135 degrees West as GOES-WEST. For more information on GOES satellites: http://www.ospo.noaa.gov/Operations/GOES/index.html</skos:definition>

text: GOES 6 was launched in April 1983 and was a NASA-developed, NOAA-operated, geosynchronous, and operational spacecraft. The cylindrically shaped spacecraft measured 190.5 cm in diameter and 230 cm in length, exclusive of a magnetometer that extended an additional 83 cm beyond the cylinder shell. The primary structural members were a honeycombed equipment shelf and thrust tube. The VISSR telescope was mounted on the equipment shelf and viewed the Earth through a special aperture in the side of the spacecraft. A support structure extended radially out from the thrust tube and was affixed to the solar panels, which formed the outer walls of the spacecraft and provided the primary source of electrical power. Located in the annulus-shaped space between the thrust tube and the solar panels were stationkeeping and dynamics control equipment, batteries, and most of the SEM equipment. Proper spacecraft attitude and spin rate (approximately 100 rpm) were maintained by two separate sets of jet thrusters mounted around the spacecraft equator and activated by ground command. The spacecraft used both UHF-band and S-band frequencies in its telemetry and command subsystem. A low-power VHF transponder provided telemetry and command during launch and then served as a backup for the primary subsystem once the spacecraft attained orbit. The spin-stabilized spacecraft carried a visible infrared spin-scan radiometer atmospheric sounder, meteorological data collection and transmission system, space environment monitor, and a biaxial fluxgate magnetometer. GOES 6 was moved from its 135 degrees West position to a more central 98 degrees West position when GOES 5 failed on July 29, 1984.

text: GOES 9 was launched on May 23, 1995. GOES-9, which is currently partially operational, is being provided to the Japanese Meteorological Agency to replace their failing geostationary satellite.  GOES I-M represents the next generation of meteorological satellites and introduces two new features.  The first feature, flexible scan, offers small-scale area imaging that lets meteorologists take pictures of local weather trouble spots. This allows them to improve short-term forecasts over local areas. The second feature, simultaneous and independent imaging and sounding, is designed to allow weather forecasters to use multiple measurements of weather phenomena to increase the accuracy of their forecasts.  Each satellite in the series carries two major instruments: an Imager and a Sounder. These instruments acquire high resolution visible and infrared data, as well as temperature and moisture profiles of the atmosphere. They continuously transmit these data to ground terminals where the data are processed for rebroadcast to primary weather services both in the United States and around the world, including the global research community.  The GOES I-M mission is scheduled to run from the mid-1990s into the first decade of the 21st century.  Each element of the mission has been designed to meet all in-orbit performance requirements for at least five years. The GOES I-M system performs the following basic functions: + Acquisition, processing, and dissemination of imaging and sounding data. + Acquisition and dissemination of Space Environment Monitor (SEM) data. + Reception and relay of data from ground-based Data Collection Platforms (DCPs) that are situated in carefully selected urban and remote areas to the NOAA Command and Data Acquisition (CDA) station. + Continuous relay of Weather Facsimile (WEFAX) and other data to users, independent of all other functions. + Relay of distress signals from people, aircraft, or marine vessels to the search and rescue ground stations of the Search and Rescue Satellite Aided Tracking (SARSAT) system. GOES provides the instantaneous relay functions for the SARSAT system. A dedicated search and rescue transponder on board GOES is designed to detect emergency distress signals originating from Earth-based sources. These unique identification signals are normally combined with signals received by a low-Earth orbiting satellite system and relayed to a search and rescue ground terminal. The combined data are used to perform effective search and rescue operations. The GOES I-M system serves a region covering the central and eastern Pacific Ocean; North, Central, and South America; and the central and western Atlantic Ocean. Pacific coverage includes Hawaii and the Gulf of Alaska. This is accomplished by two satellites, GOES West located at 135 west longitude and GOES East at 75 west longitude. A common ground station, the CDA station located at Wallops, Virginia, supports the interface to both satellites. The NOAA Satellite Operations Control Center (SOCC), in Suitland, Maryland, provides spacecraft scheduling, health and safety monitoring, and engineering analyses.  Delivery of products involves ground processing of the raw instrument data for radiometric calibration and Earth location information, and retransmission to the satellite for relay to the data user community. The processed data are received at the control center and disseminated to the National Weather Service&apos;s (NWS) National Meteorological Center, Camp Springs, Maryland, and NWS forecast offices, including the National Hurricane Center, Miami, Florida, and the National Severe Storms Forecast Center, Kansas City, Missouri. Processed data are also received by Department of Defense installations, universities, and numerous private commercial users. *The GOES-9 satellite was replaced by GOES-10 in July 1998*  MAIN SPACECRAFT DESIGN ELEMENTS Mission life            5 years, minimum Dimensions  Main body              2 meter (7 foot) cube  Deployed length        27 meters (88 feet) Weight                  2100 kg (4600 lb) Orbit                   Geosynchronous  Altitude               36,000 km (22,000 mi)  Longitude              75W and 135W  Latitude               equatorial, within 0.5 degree Power                   1050 watts @ 42 volts, solar array; battery backup Launch vehicle          Atlas-I/Centaur (GOES-I/K), Atlas-II/Centaur (GOES-L/M) Communications          Imager and Sounder in GVAR format at 2.1 Mbits/sec GOES-I/M IMAGER The GOES Imager is a multi-channel instrument designed to sense radiant and solar-reflected energy from sampled areas of the Earth. The multi-element spectral channels simultaneously sweep east-west and west-east along a north-to-south path by means of a two-axis mirror scan system. The instrument can produce full-Earth disc images, sector images that contain the edges of the Earth, and various sizes of area scans completely enclosed within the Earth scene using a new flexible scan system. Scan selection permits rapid continuous viewing of local areas for monitoring of mesoscale (regional) phenomena and accurate wind determination.

It operates independently of and simultaneously with the Imager, using a similarly flexible scan system.

A common ground station, the CDA station located at Wallops, Virginia, supports the interface to both satellites. The NOAA Satellite Operations Control Center (SOCC), in Suitland, Maryland, provides spacecraft scheduling, health and safety monitoring, and engineering analyses.  Delivery of products involves ground processing of the raw instrument data for radiometric calibration and Earth location information, and retransmission to the satellite for relay to the data user community. The processed data are received at the control center and disseminated to the National Weather Service&apos;s (NWS) National Meteorological Center, Camp Springs, Maryland, and NWS forecast offices, including the National Hurricane Center, Miami, Florida, and the National Severe Storms Forecast Center, Kansas City, Missouri. Processed data are also received by Department of Defense installations, universities, and numerous private commercial users. *The GOES-9 satellite was replaced by GOES-10 in July 1998*  MAIN SPACECRAFT DESIGN ELEMENTS Mission life            5 years, minimum Dimensions  Main body              2 meter (7 foot) cube  Deployed length        27 meters (88 feet) Weight                  2100 kg (4600 lb) Orbit                   Geosynchronous  Altitude               36,000 km (22,000 mi)  Longitude              75W and 135W  Latitude               equatorial, within 0.5 degree Power                   1050 watts @ 42 volts, solar array; battery backup Launch vehicle          Atlas-I/Centaur (GOES-I/K), Atlas-II/Centaur (GOES-L/M) Communications          Imager and Sounder in GVAR format at 2.1 Mbits/sec GOES-I/M IMAGER The GOES Imager is a multi-channel instrument designed to sense radiant and solar-reflected energy from sampled areas of the Earth. The multi-element spectral channels simultaneously sweep east-west and west-east along a north-to-south path by means of a two-axis mirror scan system. The instrument can produce full-Earth disc images, sector images that contain the edges of the Earth, and various sizes of area scans completely enclosed within the Earth scene using a new flexible scan system. Scan selection permits rapid continuous viewing of local areas for monitoring of mesoscale (regional) phenomena and accurate wind determination.

It is designed to provide data from which atmospheric temperature and moisture profiles, surface and cloud-top temperatures, and ozone distribution can be deduced by mathematical analysis. It operates independently of and simultaneously with the Imager, using a similarly flexible scan system. The Sounder&apos;s multi-element detector array assemblies simultaneously sample four separate fields or atmospheric columns. A rotating filter wheel, which brings spectral filters into the optical path of the detector array, provides the infrared channel definition.

    <skos:definition xml:lang="en">IMP-6 (IMP-I or Explorer 43, NSSDC ID: 71-019A) was a 16-sided drum-shapedspacecraft of dimensions: 1.8212 meter high and 1.3564 meter in diameter.Its mass was 635 kg.  The spacecraft spin axis was perpendicular to theecliptic plane with a spin rate of 5 rpm, giving it a spin period of12 seconds.  IMP-6 continued the study, begun by earlier IMPs, of theinterplanetary and outer magnetospheric regions by measuring energeticparticles, plasma, and electric and magnetic fields.  A radio astronomyexperiment was also included in the spacecraft payload.  The initialapogee point was near the earth-sun line.  The solar-cell and chemical-battery powered spacecraft carried two transmitters.  One continuouslytransmitted PCM encoder data at a 1600-bps information bit rate.  Thesecond transmitter was used for transmission of VLF data and for ranginginformation.  Three orthogonal pairs of dipole antennas were used forthe electric fields experiments, and one of these pairs was also usedfor the radio astronomy experiment.  The members of the antenna pairalong the spacecraft spin axis extended 2.9 meter, the members of theantennal pair used in both the electric field and radio astronomyexperiments extended 45.5 meter, and the members of the third pair wereslightly unbalanced, extending 24.4 meter and 27.6 meter, respectively.All four elements perpendicular to the spin axis were to have extended45.5 meter.  The spacecraft reentered the earth&apos;s atmosphere on October 2,1974, after a highly successful mission.  The IMP (InterplanetaryMonitoring Platform) spacecraft exploration program was carried out bythe United States._____________________________________________________________Entry taken from:  Hills, H.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

Old Value=The purpose of the Active Cavity Radiometer Irradiance Monitor III (ACRIM III)
instrument is to study total solar Irradiance from the Sun. The ACRIM III
package is flying on a spacecraft called ACRIMSAT. The spacecraft was launched
on December 20, 1999 as a secondary payload on a Taurus launch vehicle. ACRIM
III, third in a series of long-term solar-monitoring tools built for NASA by
the Jet Propulsion Laboratory, will continue to extend the database first
created by ACRIM I, which was launched in 1980 on the Solar Maximum Mission
(SMM) spacecraft. ACRIM II followed on the Upper Atmosphere Research Satellite
(UARS) in 1991. ACRIMSAT data will be correlated with possible global warming
data, ice cap shrinkage data, and ozone layer depletion data. It is theorized
that as much as 25 percent of the Earth&apos;s total global warming may be solar in
origin due to small increases in the Sun&apos;s total energy output since the last
century. By measuring incoming solar radiation and adding measurements of ocean
and atmosphere currents and temperatures, as well as surface temperatures,
climatologists will be able to improve their predictions of climate and global
warming over the next century. Energy forecasting, carbon management, public

created by ACRIM I, which was launched in 1980 on the Solar Maximum Mission
(SMM) spacecraft. ACRIM II followed on the Upper Atmosphere Research Satellite
(UARS) in 1991. ACRIMSAT data will be correlated with possible global warming
data, ice cap shrinkage data, and ozone layer depletion data. It is theorized
that as much as 25 percent of the Earth&apos;s total global warming may be solar in
origin due to small increases in the Sun&apos;s total energy output since the last
century. By measuring incoming solar radiation and adding measurements of ocean
and atmosphere currents and temperatures, as well as surface temperatures,
climatologists will be able to improve their predictions of climate and global
warming over the next century. Energy forecasting, carbon management, public
health.

Old Value=MicroLab 1, also known as OrbView 1 was launched on April 3,
1995, OrbView-1 provides the world&apos;s first broad-area
cloud-to-cloud lightning data.

OrbView-1&apos;s payload consists of two sensors:

-an Optical Transient Detector (OTD) provided by NASA&apos;s Marshall
Space Flight Center, and

-an atmospheric monitoring instrument (GPS/MET) sponsored by the
National Science Foundation and the University Consortium for
Atmospheric Research.

The OTD sensor maps atmospheric lighting strikes and has
provided NASA with information important to the understanding of
severe weather patterns. The GPS/MET sensor has proven that the
signals from the GPS satellite constellation used for precision
navigation can also be used to provide important atmospheric
data. The success of the GPS/MET sensor has further validated
the concept of using space-based sensors to improve worldwide
weather prediction.

The OrbView-1 program is the result of a unique
government-industry partnership between ORBIMAGE and NASA. Under
this arrangement, NASA provided the OTD sensor for use on
OrbView-1 and ORBIMAGE agreed to conduct an initial six-month
experiment of the sensor. NASA&apos;s cost for data under this
program over the past five years has totaled approximately
ů.2 million.

[SMAP was launched on 2015-01-31]

The Soil Moisture Active-Passive (SMAP) mission has been recommended by the NRC Earth Science Decadal Survey Panel for launch in 2015. SMAP will use a combined radiometer and high-resolution radar to measure surface soil moisture and freeze-thaw state, providing for scientific advances and societal benefits. Direct measurements of soil moisture and freeze/thaw state are needed to improve our understanding of regional water cycles, ecosystem productivity, and processes that link the water, energy, and carbon cycles. Soil moisture information at high resolution enables improvements in weather forecasts, flood and drought forecasts, and predictions of agricultural productivity and climate change.

The National Polar-orbiting Operational Environmental Satellite System (NPOESS) Integrated Program Office (IPO) has developed a tri-agency set of requirements for the next generation of polar-orbiting operational environmental satellites. A novel approach combining radar-radiometer and L-band mapping of global soil moisture will allow SMAP to far exceed the NPOESS soil moisture threshold (minimum performance) requirements for sensing depth and spatial resolution. With &quot;fast-track&quot; development, it is possible that SMAP could provide critical gap-filling soil moisture measurements for NPOESS, which were lost when the Conical Microwave Imager/Sounder was cancelled from the first NPOESS platform.

    <skos:definition xml:lang="en">The GEOTAIL mission is a collaborative project undertaken by the Institute ofSpace and Astronautical Science (ISAS) and the National Aeronautics and SpaceAdministration (NASA). Its primary objective is to study the dynamics of theEarth&apos;s magnetotail over a wide range of distance, extending from thenear-Earth region (8 Earth radii (Re) from the Earth) to the distant tail(about 200 Re). The GEOTAIL spacecraft was designed and built by ISAS and waslaunched on July 24, 1992.The Geotail mission measures global energy flow and transformation in themagnetotail to increase understanding of fundamental magnetospheric processes.This will include the physics of the magnetopause, the plasma sheet, andreconnection and neutral line formation (i.e., the mechanisms of input,transport, storage, release and conversion of energy in the magnetotail).Geotail, together with Wind, Polar, SOHO, and Cluster projects, constitute acooperative scientific satellite project designated the InternationalSolar-Terrestrial Physics (ISTP) program which aims at gaining improvedunderstanding of the physics of solar terrestrial relations.Geotail is a spin-stabilized spacecraft utilizing mechanically despun antennaswith a design lifetime of about four years. The nominal spin rate of thespacecraft is about 20 rpm around a spin axis maintained between 85 and 89 degto the ecliptic plane. Geotail is cylindrical, approximately 2.2 m in diameterand 1.6 m high with body-mounted solar cells. Geotail also has a two-hourback-up battery subsystem which operates when the spacecraft is in the Earth&apos;sshadow.Real-time telemetry data transmitted in the X-band are received at the UsudaDeep Space Center (UDSC) in Japan. There are two tape recorders on board, eachwith a capacity of 450 Mbit which allow daily 24-hour data coverage. The dataare collected in playback mode by the NASA Deep Space Network (DSN).The Geotail mission is divided into two phases. During the two-year initialphase, the orbit apogee was kept on the nightside of the Earth by using theMoon&apos;s gravity in a series of double-lunar swing-by maneuvers that result inthe spacecraft spending most of its time in the distant magnetotail (maximumapogee about 200 Earth radii) with a period varying from one to four months.Then, starting in November 1994, there were a series of maneuvers to bring thespacecraft into its near-Earth orbit. This transition orbit lasted about threemonths with the apogee varying from 50 RE to 30 RE. The second phase isdedicated to the study of near-Earth magnetospheric processes, includingneutral line formation.The GEOTAIL mission consists of the following experiments:- Comprehensive Plasma Investigation (CPI)- Electric Fields Detector (EFD)- Energetic Particle and Ion Composition (EPIC)- High-Energy Particles (HEP)- Low-Energy Particles (LEP)- Magnetic Field Experiment- Plasma Waves Investigation (PWI)For more information, see:http://pwg.gsfc.nasa.gov/geotail.shtmlGroup: Platform_Details   Entry_ID: GEOTAIL   Group: Platform_Identification      Platform_Category: Solar/Space Observation Satellites      Short_Name: GEOTAIL   End_Group   Group: Synonymous_Platform_Names      Short_Name: GGS/Geotail      Short_Name: GTL      Short_Name: Geomagnetic Tail Lab      Short_Name: ISTP/Geotail      Short_Name: 22049      Short_Name: 1992-044A   End_Group   Group: Platform_Associated_Instruments      Short_Name: MFE      Short_Name: PWI      Short_Name: LEP      Short_Name: HEP      Short_Name: EPIC      Short_Name: EFD      Short_Name: CPI-G   End_Group   Group: Orbit      Orbit_Inclination: 5.15 degrees - 7.45 degrees      Period: 43 days - 49 days      Perigee: 47,835 km - 51,024 km      Apogee: 869,421 km - 191,340 km      Orbit_Type: HEO &gt; Highly Elliptical Orbit   End_Group   Online_Resource: http://pwg.gsfc.nasa.gov/geotail.shtml   Online_Resource: http://www.stp.isas.ac.jp/geotail/   Sample_Image: http://nssdc.gsfc.nasa.gov/image/spacecraft/geotail.jpg   Group: Platform_Logistics      Launch_Date: 1992-07-24      Launch_Site: Cape Canaveral/Kennedy Space Center, USA      Primary_Sponsor: ISAS, Japan      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

Old Value=The Coastal-Marine Automated Network (C-MAN) was established by NDBC for the NWS in the early 1980&apos;s. The development of C-MAN was in response to a need to maintain meteorological observations in U. S. coastal areas. Such observations, which had been made previously by USCG personnel, would have been lost as many USCG navigational aids were automated under the Lighthouse Automation and Modernization Program (LAMPS). In all, approximately 60 stations make up C-MAN.

C-MAN stations have been installed on lighthouses, at capes and beaches, on near shore islands, and on offshore platforms (see the NDBC station location map for all station locations).

C-MAN station data typically include barometric pressure, wind direction, speed and gust, and air temperature; however, some C-MAN stations are designed to also measure sea water temperature, water level, waves, relative humidity, precipitation, and visibility. These data are processed and transmitted hourly to users in a manner almost identical to moored buoy data. In addition to the conventional method of data transmission, certain C-MAN stations are equipped with telephone modems that allow more frequent data acquisition, data quality checking, and remote payload reconfiguration or restarting.

text: In the first decade of the 21st century, China is in the process of developing its own navigation satellite constellation known as CNSS (Compass Navigation Satellite System), or BeiDou-2 in its Chinese name. BeiDou is the Chinese name of the Big Dipper constellation. The BeiDou-2 system will be based on its current regional Compass Satellite Navigation Experimental System (BeiDou-1).

Although the program was initiated by China&apos;s military forces, China established an agency, namely CSNPC (China Satellite Navigation Project Center) in the timeframe 2006/7, to take charge of the research, building, and management of CNSS.

The BeiDou-2 program was officially started in 2005 and announced by China in October 2006. China gave also to a proper name to the rest of the world of its BeiDou-2 system, namely CNSS (Compass Navigation Satellite System) - BeiDou literally means &quot;Compass&quot;. The new system will be a constellation of 35 satellites, which include 5 geostationary orbit (GEO) satellites and 30 medium Earth orbit (MEO) satellites, that will offer complete coverage of the globe.

China has joined the UN-supported ICG (International Committee on GNSS) and has taken part in the ICG&apos;s Providers Forum (founded in Sept. 2007, Bangalore, India). The members of the Forum and their current and future systems include: China (CNSS), EU (Galileo, EGNOS), India (IRNSS, GAGAN), Japan (QZSS, MSAS), Russia (GLONASS), and USA (GPS, WAAS). The goal of the Providers Forum is to foster compatibility of the services/signals and interoperability among the various navigation systems for a better service to the user community. 

The Chinese plans call for a deployment of the full constellation by 2012. A more realistic timeframe for global service provision is probably 2015. China plans call also for a long-term and sustained navigation service and system performance for the global user community once the system is in full operation. 4) 5)

In 2009, three BeiDou-2 spacecraft are planned to be launched. More than 10 satellites will be put into service within the next two years by Long-March launchers. Around 2011, the system will be capable to offer services on a regional scale.

text: The first proposal to use satellites for navigation was made by V.S.Shebashevich in 1957. This idea was born during the investigation of the possible application of radio-astronomy technologies for aeronavigation. Further investigations were conducted in a number of the Soviet institutions to increase the accuracy of navigation definitions, global support, daily application and independence from weather conditions. The research results were used in 1963 for R&amp;D project on the first Soviet low-orbit “Cicada” system. In 1967 the first navigation Soviet satellite &quot;Cosmos-192&quot; was launched. The navigation satellite provided continuous radio navigation signal transmission on 150 and 400 MHz during its active lifetime.

The “Cicada” system of four satellites was commissioned in 1979. The navigation satellites were placed into circular orbits 1,000 km high with an inclination of 83 ° and equal distribution of orbital planes to the equator. It allowed users to acquire one of the satellites every hour and a half or two and fix the position within 5-6 min of a navigation session. The navigation system “Cicada” used one-way user-to-satellite range measurements. Along with improvement of the satellite onboard systems and navigation equipment much attention was given to enhancing accuracy of determining and predicting parameters of the navigation satellite orbits.

Later, receiving measuring equipment was disposed on the “Cicada” satellites to detect distress radiobeacons. The satellites received these signals and rebroadcast them to special ground stations where the computation of the exact coordinates of the emergency objects (ships, aircraft, etc.) was held. The “Cicada” satellites tracking distress radiobecons formed “Cospas” system that together with the US-French-Canadian &quot;Sarsat&quot; system built an integrated search and rescue service that saved several thousands of lives. The “Cicada” space navigation system (and its “Cicada-M” modernization) was designed for navigation support of military users and had been in use since 1976. In 2008 “Cicada” and “Cicada-M” users started to use GLONASS system and the operation of those systems was halted. It was impossible for the low-orbit systems to meet requirements of a great number of users.

Successful operation of the low-orbit satellite navigation systems by the marine users attracted widespread attention to satellite navigation. A general-purpose navigation system was needed to meet the requirements of the great majority of prospective users.

Based on the all-round research it was decided to choose the orbital constellation consisting of 24 satellites equally distributed in three orbital planes inclined at 64.8° to the equator. The GLONASS satellites are placed in roughly circular orbits with the nominal orbit altitude 19,100 km and an orbital period of 11 hours, 15 minutes, 44 seconds. Due to the period value it became possible to create a sustainable orbital system that unlike GPS does not require supporting correcting pulses during its active lifetime. The nominal inclination ensures global availability on the territory of the Russian Federation even when several SVs are not operational.

Two challenges have been faced for designing a high-orbit navigation system. The first one dealt with mutual synchronized satellite timescales with the accuracy of billionths of a second (nanoseconds). It became possible because of high-orbit onboard caesium frequency standards with nominal stability at 10-13 and ground hydrogen frequency standard with nominal stability at 10-14 and also because of ground facilities of time scale comparison with error of 3-5 ns. The second challenge addressed high-precision determination and prediction of navigation satellite orbit parameters. This issue was solved with scientific research on second order factors of infinitesimals, such as light pressure, irregularities of the Earth rotation and polar motions and etc.

Flight tests of the Russian high orbit satellite navigation system, called GLONASS, were started in October, 1982 with the launch of “Kosmos-1413” satellite. The GLONASS system was formally declared operational in 1993. In 1995 it was brought to a fully operational constellation (24 GLONASS satellites of the first generation). A great drawback that should have been focused on consisted in the lack of civil navigation equipment and civil users.

Reduction in funding for space industry in 1990 led to degradation of the GLONASS constellation. In 2002 the GLONASS constellation consisted of 7 satellites that was insufficient for navigation support of the Russian territory even with limited availability. GLONASS was behind GPS in accuracy characteristics, SVs active lifetime comprised 3-4 years.

    <skos:definition xml:lang="en">The first proposal to use satellites for navigation was made by V.S.Shebashevich in 1957. This idea was born during the investigation of the possible application of radio-astronomy technologies for aeronavigation. Further investigations were conducted in a number of the Soviet institutions to increase the accuracy of navigation definitions, global support, daily application and independence from weather conditions. The research results were used in 1963 for R&amp;D project on the first Soviet low-orbit “Cicada” system. In 1967 the first navigation Soviet satellite &apos;Cosmos-192&apos; was launched. The navigation satellite provided continuous radio navigation signal transmission on 150 and 400 MHz during its active lifetime.The “Cicada” system of four satellites was commissioned in 1979. The navigation satellites were placed into circular orbits 1,000 km high with an inclination of 83 ° and equal distribution of orbital planes to the equator. It allowed users to acquire one of the satellites every hour and a half or two and fix the position within 5-6 min of a navigation session. The navigation system “Cicada” used one-way user-to-satellite range measurements. Along with improvement of the satellite onboard systems and navigation equipment much attention was given to enhancing accuracy of determining and predicting parameters of the navigation satellite orbits.Later, receiving measuring equipment was disposed on the “Cicada” satellites to detect distress radiobeacons. The satellites received these signals and rebroadcast them to special ground stations where the computation of the exact coordinates of the emergency objects (ships, aircraft, etc.) was held. The “Cicada” satellites tracking distress radiobecons formed “Cospas” system that together with the US-French-Canadian &apos;Sarsat&apos; system built an integrated search and rescue service that saved several thousands of lives. The “Cicada” space navigation system (and its “Cicada-M” modernization) was designed for navigation support of military users and had been in use since 1976. In 2008 “Cicada” and “Cicada-M” users started to use GLONASS system and the operation of those systems was halted. It was impossible for the low-orbit systems to meet requirements of a great number of users.Successful operation of the low-orbit satellite navigation systems by the marine users attracted widespread attention to satellite navigation. A general-purpose navigation system was needed to meet the requirements of the great majority of prospective users.Based on the all-round research it was decided to choose the orbital constellation consisting of 24 satellites equally distributed in three orbital planes inclined at 64.8° to the equator. The GLONASS satellites are placed in roughly circular orbits with the nominal orbit altitude 19,100 km and an orbital period of 11 hours, 15 minutes, 44 seconds. Due to the period value it became possible to create a sustainable orbital system that unlike GPS does not require supporting correcting pulses during its active lifetime. The nominal inclination ensures global availability on the territory of the Russian Federation even when several SVs are not operational.Two challenges have been faced for designing a high-orbit navigation system. The first one dealt with mutual synchronized satellite timescales with the accuracy of billionths of a second (nanoseconds). It became possible because of high-orbit onboard caesium frequency standards with nominal stability at 10-13 and ground hydrogen frequency standard with nominal stability at 10-14 and also because of ground facilities of time scale comparison with error of 3-5 ns. The second challenge addressed high-precision determination and prediction of navigation satellite orbit parameters. This issue was solved with scientific research on second order factors of infinitesimals, such as light pressure, irregularities of the Earth rotation and polar motions and etc.Flight tests of the Russian high orbit satellite navigation system, called GLONASS, were started in October, 1982 with the launch of “Kosmos-1413” satellite. The GLONASS system was formally declared operational in 1993. In 1995 it was brought to a fully operational constellation (24 GLONASS satellites of the first generation).

Old Value=TIROS-7 Objectives:

Continue research and development of the meteorological
satellite information system; obtain improved data for use in
weather forecasting, especially during hurricane season.

Description:

The spacecraft was 42 inches in diameter, 19 inches high and
weighed 270 pounds. The craft was made of aluminum alloy and
stainless steel then covered by 9200 solar cells. The solar
cells served to charge the nickel-cadmium (nicad)
batteries. Three pairs of solid-propellant spin rockets were
mounted on the base plate.

TIROS-7 was also designed to make infrared measurements of
reflected solar and terrestrial radiation over selected spectrum
ranges and gather data on electron density and temperature in
space. To accomplish this new expanded mission, TIROS-7 carried
two wide-angle camera systems, a magnetic tape recorder, and
infrared experimentation equipment. The electron density and
temperature probes were the same as the ones flown on board
Explorer 17.

The spacecraft operating system still included the infrared
horizon scanner, the north direction indicator, despin weights
and spinup rockets, and the magnetic attitude control
system. TIROS-7 was deactivated after furnishing over 30,000
cloud photographs; it lasted the longest of the TIROS series
thus far, 1809 days.

Its primary  objective  was  to  obtain  worldwide  observations  of total electron  content between the spacecraft and the earth.  The satellite was  initially  spin  stabilized, but it was despun after solar paddle erection.   Subsequent  stabilization  oriented  the satellite axis of symmetry with the local magnetic field by means of a strong bar magnet and  damping rods.  A three-axis magnetometer and sun sensors provided information  on  the  satellite  attitude and spin rate.  There was no tape   recorder   aboard   so  that  satellite  performance  data  and electrostatic  probe  data  were  observed only when the satellite was within  range  of a ground telemetry station.  Continuous transmitters operated  at  162  and 324 MHz to permit precise tracking by &apos;Transit&apos; tracking  stations for navigation and geodetic studies.

Old Value=COSMO-SkyMed (Constellation of Small Satellites for Mediterranean basin Observation) is a 4-spacecraft constellation, conceived by ASI (Agenzia Spaziale Italiana), and funded by the Italian Ministry of Research (MUR) and the Italian Ministry of Defense (MOD), Rome, Italy. The program is managed in cooperation by ASI and MOD. Each of the four satellites is equipped with a SAR (Synthetic Aperture Radar) instrument and is capable of operating in all visibility conditions at high resolution and in real time.

The overall objective of this program is global Earth observation and the relevant data exploitation for the needs of the military community as well as for the civil (institutional, commercial) community.

Sample applications of COSMO-SkyMed data are seen the following fields:

• Defense and security applications: Surveillance, intelligence, mapping, damage assessment, vulnerability assessment, target detection/localization

• Risk management applications: Floods, droughts, landslides, volcanic/seismic, forest fire, industrial hazards, water pollution

• Other applications: Marine and coastal environments, agriculture, forestry, cartography, environment, geology and exploration, telecommunication, utilities and planning

• Provision of commercial imaging services

• The high revisit frequency offered by the four X-band SAR spacecraft is also expected to provide a unique potential to the operational meteorological user community through provision of ancillary data and/or data on meteo-correlated phenomena, in particular as regards sea ice monitoring and study of ocean wave patterns.

Background: In 1996 the Italian Government provided initial funding for the realization of a national Earth observation program. In 1997 the general guidelines for the 1998-2002 Italian National Space Plan (PSN) were approved including the activities on Earth observation. The strategic element in this plan is the COSMO-SkyMed dual-use program of ASI. 1) 2)

In the summer of 2001, the Italian Ministry of Defense became a partner in the COSMO-SkyMed program (a welcome funding partner for the Italian Ministry of Research). However, the dual-use nature of the COSMO-SkyMed program, i. e. civil (research and commercial) and military use of its data products, resulted in a virtually classified program. A great disadvantage of the new arrangement is that rather sparse technical information of the mission can only be made available to the public.

Although the first constellation satellite SAR instruments (SAR-2000) will observe in X-band (9.6 GHz with a wavelength of 3.1 cm), multi-mode scenarios (X-, C- L- and P-band) are planned for the future.

The overall system architecture is composed of a space segment, a constellation of SAR satellites, and a ground segment including full featured user services. The requirements call for the following general performance characteristics: 3)

• Full global observation coverage with all weather, day/night acquisition capability

• Collection capability of large areas within a single pass, with along-track stereo imaging during a single pass

• High image quality, to allow a robust image interpretability at the requested scale of analysis (data sets are characterized by adequate spatial and spectral resolution suitable to perform analyses at different scales of detail)

• Ground track repeatability: the satellites of the SAR constellation shall have a ground track repeatability of better than 1 km

• Fast response times (from the data/service user request up to the data/service delivery to that requiring user).

The SABRINA project was started in 2004/5. 

The COSMO-SkyMed space segment is composed of a constellation of four SAR satellites. The PRIMA \[Piattaforma Riconfigurabile Italiana Multi-Applicativa (Reconfigurable Italian Platform for Multiple Applications)\] bus of Alcatel Alenia Space is being employed. Alcatel Alenia Space is also the prime contractor of the space segment \[funding by ASI and I-AD (Ministry of Defense)\]. - Note: As of April 10, 2007, the EC approved the transfer to Thales of Alcatel-Lucent&apos;s shareholdings in the two space sector joint venture companies Alcatel Alenia Space and Telespazio. Hence, Alcatel Alenia Space was renamed to Thales Alenia Space.

The S/C is three-axis stabilized, it consists of the main body (bus), two deployable solar arrays, and a SAR antenna. The bus provides all support functions like: AOCS, electrical power (power generation, storage and distribution), data handling, thermal control, RF communications, and on-orbit propulsion for orbit injection and maintenance. The platform mechanical configuration consists of two elements or modules, namely:

• SVM (Service Module) at the bottom of the bus which contains all bus subsystems including the propulsion module

• PLM (Payload Module) at the top, dedicated to the payload complement, the PDHT (Payload Data Handing and Transmission) subsystem, and the AOCS (Attitude and Orbit Control Subsystem) with star trackers gyros actuators.

The bus structure material is CFRP (Carbon Fiber Reinforced Plastic) while SVM and PLM consist of aluminum alloys. The interfaces of the SAR antenna, star trackers and gyros are mounted on the CFRP structure for pointing precision and stability (a star tracker is being used as well as a high-quality GPS receiver). The SSTI (Satellite-to-Satellite Tracking Instrument) is the LAGRANGE GPS receiver of Laben SpA. The SAR antenna bore sight is pointing with an incidence angle about 38º to the right side of the S/C ground track. AOCS provides an antenna steering capability of ±2º in yaw as well as for a re-pointing capability to the left side of the ground track. Each S/C in the constellation features a RCT (Reaction Control Thruster) system for orbit maintenance.

The mass of each spacecraft is about 1700 kg. The design life is 5 years. The S/C provides an onboard operational autonomy for a period of 24 hours. 

Launch: The launch of the first COSMO spacecraft in the constellation took place on June 8, 2007 (UTC). The launch was provided by the Boeing Company on a Delta-2 (7420-10 configuration) vehicle from VAFB, CA. This represented the first commercial Delta-2 launch since the formation of the United Launch Alliance (ULA) in December 2006.

Circular sun-synchronous dawn-dusk orbit, nominal altitude = 619.6 km, inclination = 97.86º, period = 97.1 min, with LTAN (Local Time of Ascending Node) at 6:00 AM, 14.8125 rev./day (or 14 13/16). All spacecraft of the SAR constellation will be positioned in the same orbital plane with a phasing outlined in Table 2. The nominal repeat cycle is 16 days; however, each single satellite will have a near revisit time of 5 days.

The overall system architecture is composed of a space segment, a constellation of SAR satellites, and a ground segment including full featured user services. The requirements call for the following general performance characteristics: 3)

• Full global observation coverage with all weather, day/night acquisition capability

• Collection capability of large areas within a single pass, with along-track stereo imaging during a single pass

• High image quality, to allow a robust image interpretability at the requested scale of analysis (data sets are characterized by adequate spatial and spectral resolution suitable to perform analyses at different scales of detail)

• Ground track repeatability: the satellites of the SAR constellation shall have a ground track repeatability of better than 1 km

• Fast response times (from the data/service user request up to the data/service delivery to that requiring user).

The SABRINA project was started in 2004/5. 

The COSMO-SkyMed space segment is composed of a constellation of four SAR satellites. The PRIMA \[Piattaforma Riconfigurabile Italiana Multi-Applicativa (Reconfigurable Italian Platform for Multiple Applications)\] bus of Alcatel Alenia Space is being employed. Alcatel Alenia Space is also the prime contractor of the space segment \[funding by ASI and I-AD (Ministry of Defense)\]. - Note: As of April 10, 2007, the EC approved the transfer to Thales of Alcatel-Lucent&apos;s shareholdings in the two space sector joint venture companies Alcatel Alenia Space and Telespazio. Hence, Alcatel Alenia Space was renamed to Thales Alenia Space.

The S/C is three-axis stabilized, it consists of the main body (bus), two deployable solar arrays, and a SAR antenna. The bus provides all support functions like: AOCS, electrical power (power generation, storage and distribution), data handling, thermal control, RF communications, and on-orbit propulsion for orbit injection and maintenance. The platform mechanical configuration consists of two elements or modules, namely:

• SVM (Service Module) at the bottom of the bus which contains all bus subsystems including the propulsion module

• PLM (Payload Module) at the top, dedicated to the payload complement, the PDHT (Payload Data Handing and Transmission) subsystem, and the AOCS (Attitude and Orbit Control Subsystem) with star trackers gyros actuators.

The bus structure material is CFRP (Carbon Fiber Reinforced Plastic) while SVM and PLM consist of aluminum alloys. The interfaces of the SAR antenna, star trackers and gyros are mounted on the CFRP structure for pointing precision and stability (a star tracker is being used as well as a high-quality GPS receiver). The SSTI (Satellite-to-Satellite Tracking Instrument) is the LAGRANGE GPS receiver of Laben SpA. The SAR antenna bore sight is pointing with an incidence angle about 38º to the right side of the S/C ground track. AOCS provides an antenna steering capability of ±2º in yaw as well as for a re-pointing capability to the left side of the ground track. Each S/C in the constellation features a RCT (Reaction Control Thruster) system for orbit maintenance.

The mass of each spacecraft is about 1700 kg. The design life is 5 years. The S/C provides an onboard operational autonomy for a period of 24 hours. 

Launch: The launch of the first COSMO spacecraft in the constellation took place on June 8, 2007 (UTC). The launch was provided by the Boeing Company on a Delta-2 (7420-10 configuration) vehicle from VAFB, CA. This represented the first commercial Delta-2 launch since the formation of the United Launch Alliance (ULA) in December 2006.

Circular sun-synchronous dawn-dusk orbit, nominal altitude = 619.6 km, inclination = 97.86º, period = 97.1 min, with LTAN (Local Time of Ascending Node) at 6:00 AM, 14.8125 rev./day (or 14 13/16). All spacecraft of the SAR constellation will be positioned in the same orbital plane with a phasing outlined in Table 2. The nominal repeat cycle is 16 days; however, each single satellite will have a near revisit time of 5 days.

Old Value=COSMO-SkyMed (Constellation of Small Satellites for Mediterranean basin Observation) is a 4-spacecraft constellation, conceived by ASI (Agenzia Spaziale Italiana), and funded by the Italian Ministry of Research (MUR) and the Italian Ministry of Defense (MOD), Rome, Italy. The program is managed in cooperation by ASI and MOD. Each of the four satellites is equipped with a SAR (Synthetic Aperture Radar) instrument and is capable of operating in all visibility conditions at high resolution and in real time.

The overall objective of this program is global Earth observation and the relevant data exploitation for the needs of the military community as well as for the civil (institutional, commercial) community.

Sample applications of COSMO-SkyMed data are seen the following fields:

• Defense and security applications: Surveillance, intelligence, mapping, damage assessment, vulnerability assessment, target detection/localization

• Risk management applications: Floods, droughts, landslides, volcanic/seismic, forest fire, industrial hazards, water pollution

• Other applications: Marine and coastal environments, agriculture, forestry, cartography, environment, geology and exploration, telecommunication, utilities and planning

• Provision of commercial imaging services

• The high revisit frequency offered by the four X-band SAR spacecraft is also expected to provide a unique potential to the operational meteorological user community through provision of ancillary data and/or data on meteo-correlated phenomena, in particular as regards sea ice monitoring and study of ocean wave patterns.

Background: In 1996 the Italian Government provided initial funding for the realization of a national Earth observation program. In 1997 the general guidelines for the 1998-2002 Italian National Space Plan (PSN) were approved including the activities on Earth observation. The strategic element in this plan is the COSMO-SkyMed dual-use program of ASI. 1) 2)

In the summer of 2001, the Italian Ministry of Defense became a partner in the COSMO-SkyMed program (a welcome funding partner for the Italian Ministry of Research). However, the dual-use nature of the COSMO-SkyMed program, i. e. civil (research and commercial) and military use of its data products, resulted in a virtually classified program. A great disadvantage of the new arrangement is that rather sparse technical information of the mission can only be made available to the public.

    <skos:definition xml:lang="en">Pioneer 6 was the first of four NASA spacecraft designed to study interplanetary phenomena in space. The spacecraft successfully provided simultaneous scientific measurements at widely dispersed locations in heliocentric orbit. It returned the first data on the tenuous solar atmosphere and later recorded the passage of Comet Kohoutek&apos;s tail in 1974. Along with Pioneers 7, 8, and 9, the spacecraft formed a ring of solar weather stations spaced along Earth&apos;s orbit. Measurements by the four Pioneers were used to predict solar storms for approximately 1,000 primary users, including the Federal Aviation Administration; commercial airlines; power companies; communication companies; military organizations; and entities involved in surveying, navigation, and electronic prospecting. By December 1990, Pioneer 6 had circled the Sun twentynine times (traveling 24.8 billion kilometers) and had been operational for twenty years -- a record for a deep space probe. Its original slated lifetime had been only six months. On 15 December 1996, the spacecraft&apos;s primary transmitter failed, but during a track on 11 July 1996, ground controllers switched on the backup transmitter. Of the spacecraft&apos;s six scientific instruments, two (the plasma analyzer and the cosmic-ray detector) still continue to function. NASA maintains contact with the spacecraft once or twice each year. For example, 1 hour&apos;s worth of scientific data was collected on 29 July and 15 December 1995 (although the primary transmitter failed soon after that), and again on 6 October 1997, more than thirty years after launch. The probe&apos;s solar arrays continue to deteriorate, although the transmitters can be turned on at perihelion when the solar flux is strong enough to provide sufficient power. On 8 December 2000, to commemorate its thirty-fifth anniversary of operation, ground controllers established successful contact with the spacecraft for about 2 hours.Information provided by http://solarsystem.nasa.gov/missions/profile.cfm?Sort=Alpha&amp;Alias=Pioneer%206&amp;Letter=P&amp;Display=ReadMoreGroup: Platform_Details   Entry_ID: PIONEER 6   Group: Platform_Identification      Platform_Category: Solar/Space Observation Satellites      Short_Name: PIONEER 6   End_Group   Group: Platform_Associated_Instruments      Short_Name: WAVES      Short_Name: MUON COSMIC RAY DETECTORS      Short_Name: PROBES      Short_Name: FLUXGATE MAGNETOMETERS   End_Group   Creation_Date: 2007-08-20   Online_Resource: http://solarsystem.nasa.gov/missions/profile.cfm?Sort=Alpha&amp;Alias=Pioneer%206&amp;Letter=P&amp;Display=ReadMore   Sample_Image: http://solarsystem.nasa.gov/missions/images/miss-pioneer_06.gif   Group: Platform_Logistics      Launch_Date: 1965-12-16      Design_Life: 6 months      Primary_Sponsor: NASA   End_GroupEnd_Group</skos:definition>

    <skos:definition xml:lang="en">BE-B   (Explorer  22)  was  a  small  ionospheric  research  satellite instrumented  with an electrostatic probe, a 20-, 40-, and 41-Hz radio beacon,  a  passive laser tracking reflector, and a Doppler navigation experiment.   Its  objective  was  to obtain worldwide observations of total  electron  content  between  the  spacecraft and the earth.  The satellite was initially spin-stabilized, but it was despun after solar paddle erection.  Subsequent stabilization oriented the satellite axis of  symmetry  with  the  local magnetic field by means of a strong bar magnet  and  damping  rods.  A three-axis magnetometer and sun sensors provided  information  on the satellite attitude and spin rate.  There was  no  tape  recorder  aboard so that satellite performance data and electrostatic probe data could be observed only when the satellite was within  range  of a ground telemetry station.  Continuous transmitters also  operated  at  162  and  324  MHz  to  permit precise tracking by &apos;Transit&apos;  tracking  stations for navigation and geodetic studies.  In August  1968,  data  acquisition from the satellite telemetry channels was  discontinued.   In  July  1969, tracking and world map production were  discontinued  by  GSFC,  and world map production based on NORAD orbit elements was subsequently assumed by ESRO.  The satellite failed in  February  1970  and  BE-C  was  turned  on  in order to  partially replace use made of this satellite beacon experiment.
