    <skos:definition xml:lang="en">DMSP Satellite F13 was built by General Electrics Astro-SpaceDivision (now part of Martin Marietta Astro Space). It waslaunched on March 24, 1995 from Vandenberg AFB, California usingan Atlas E rocket. The spacecraft is 3.7 meters in length with adiameter of 1.2 meters with an on-orbit mass of 831kilograms. It has a design lifetime of 48 months. Power isprovided though a 9.29 sq-m solar cell panel. Attitude iscontrolled using momentum wheels and magnetic coils using astrap-down star sensor and gyros as the reference.Characteristics:Maximum Altitude: 856 kmMinimum Altitude: 844 kmInclination: 98.8 degPeriod: 102.0 minutesEccentricity: 0.00083Ascending Equator Crossing Time (Local Time):At Launch: 17:42Current (09/02/95): 17:43Swath Width:Visible and Infrared Imagery - 3000 kmMicrowave Imagery - 1400 kmTemperature Sounder - 1500 kmWater Vapor Profiler - 1500 kmLaunch Date - March 24, 1995End Mission (Operational Support - F13 is currently (9/02/95)providing primary support with sensors OLS, SSM/I, SSM/T,SSM/T-2, SSJ/4, SSIES2, SSM, SSB/X and SSZ still providing data.Additional information available at&apos;http://ghrc.msfc.nasa.gov:5721/source_documents/dmsp_f13.html&apos;and&apos;http://dmsp.ngdc.noaa.gov/dmsp.html&apos;[Summary provided by GHRC]Group: Platform_Details   Entry_ID: DMSP 5D-2/F13   Group: Platform_Identification      Platform_Category: Earth Observation Satellites      Platform_Series_or_Entity: DMSP (Defense Meteorological Satellite Program)      Short_Name: DMSP 5D-2/F13      Long_Name: Defense Meteorological Satellite Program-F13   End_Group   Group: Synonymous_Platform_Names      Short_Name: DMSP-F13      Short_Name: USA 109      Short_Name: 23533   End_Group   Group: Platform_Associated_Instruments      Short_Name: SSM      Short_Name: SSM/T-2      Short_Name: OLS      Short_Name: SSI/ES2      Short_Name: SSJ/4      Short_Name: SSM/I      Short_Name: SSB/X2      Short_Name: SSM/T      Short_Name: SSJ   End_Group   Group: Orbit      Orbit_Inclination: 98.8°      Period: 101.9 minutes      Perigee: 845.0 km  	      Apogee: 851.0 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=1995-015A   Online_Resource: http://heasarc.gsfc.nasa.gov/docs/heasarc/missions/dmsp.html   Online_Resource: http://ghrc.msfc.nasa.gov:5721/source_documents/dmsp_f13.html    Online_Resource: http://dmsp.ngdc.noaa.gov/dmsp.html    Group: Platform_Logistics      Launch_Date: 1995-03-24      Launch_Site: Vandenberg Air Force Base, USA      Primary_Sponsor: Department of Defense-Department of the Air Force (United States)   End_GroupEnd_Group</skos:definition>
