1975-100A
In 1975 the SMS C satellite was renamed GOES A to reflect its operational mission. The 293 kg GOES A was launched at 2240 on 1975 Oct 16 by a Delta 2914 rocket from Cape Canaveral. At 2249 the Delta second stage reached a 187 x 930 km x 27 deg orbit; the Star 37E third stage fired to place the payload in a 200 x 36796 km transfer orbit at 2304. Geostationary Operational Environmental Satellite 01 fired its solid apogee motor at 1451 on Oct 17, entering synchronous orbit at 65 deg W with a 2 deg W per day drift. On Oct 25 it was stopped at 55 deg W to begin on orbit testing. GOES 1 was declared operational on 1976 Jan 8, and control was switched from NASA to the NOAA-NESS ground station in Wallops Island, Virginia. GOES 1 was later moved over the Pacific at 135W. In 1978 Jun the EPM and Solex experiments failed. Also in 1978, the satellite was assigned to the European Space Agency as part of the Global Atmospheric Research Program (GARP). It was moved to 10W for training of ESA controllers at the Villafranca, Spain, ground station, and then to the Indian Ocean where it took part in the First GARP Global Experiment (FGGE). In Dec 1979 GOES 1 was returned to NOAA's control and sent to the GOES-W position at 135W. In Mar 1980 it was placed on standby at 93W, and on Jun 18 operational transmissions were ended. In 1980-82 it was stored near 120-130W, but then its VISSR imager was reactivated to replace the failed GOES 4 and it was moved to 126W. The end of the mission came in 1985: on Feb 3 GOES 1's radiometer failed and the satellite was switched off and allowed to drift in the geostationary ring between 81W and 130W.
