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 'http://www.esa.int/SPECIALS/MSG/'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 > Geosynchronous > 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 2016-06-09 11:34:01.0
