GOES-4 , known as GOES-D before becoming operational, was a geostationary weather satellite which was operated by the United States National Oceanic and Atmospheric Administration as part of the Geostationary Operational Environmental Satellite system. [1] Launched in 1980, it was used for weather forecasting in the United States, and later in Europe . Following its retirement it became the first satellite to be sent into a graveyard orbit .

Limited lifespan [ edit ]

Launch of GOES-D on a Delta 3914

GOES-4 was built by Hughes Space and Communications , and was based around the HS-371 satellite bus . At launch it had a mass of 660 kilograms (1,460 lb), [2] with an expected operational lifespan of around seven years. [3] It was the first HS-371 based GOES satellite. [4]

Launch and orbit [ edit ]

GOES-D was launched using a Delta 3914 carrier rocket flying from Launch Complex 17A at the Cape Canaveral Air Force Station . [5] The launch occurred at 22:27 GMT on 9 September 1980. [6] The launch successfully placed GOES-D into a geosynchronous transfer orbit , from which it raised itself to geostationary orbit by means of an onboard Star-27 apogee motor. Its insertion into geostationary orbit occurred at 12:00 on 11 September. [7]

Following its insertion into geostationary orbit, GOES-4 was positioned at 98° West. In 1981, it was moved to 135° West, where it remained until 1983 when it was moved to 139° West (1983?1984). In 1985 it was repositioned at 10° West, and later 44° West, where it provided coverage of Europe for EUMETSAT following the failure of the Meteosat-2 spacecraft. [8]

Graveyard orbit [ edit ]

Following the end of its operations over Europe, GOES-4 was retired from service. It became the first spacecraft to be raised out of geosynchronous orbit, into a graveyard orbit for disposal. [9] This was accomplished on 9 November 1988, using remaining propellent in the satellite's station-keeping thrusters.
