GOES-7, known as GOES-H before becoming operational, is an American satellite. It was originally built as a weather satellite, and formed part of the US National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite system. Originally built as a ground spare, GOES-H was launched in 1987 due to delays with the next series of satellites. It was operated by NOAA until 1999, before being leased to Peacesat, who use it as a communications satellite. As of 2009, it was operational over the Pacific Ocean, providing communications for the Pacific Islands. On April 12, 2012, the spacecraft was finally decommissioned and moved to a graveyard orbit.
GOES-H was launched aboard a McDonnell Douglas Delta 3914 rocket, flying from Launch Complex 17A at the Cape Canaveral Air Force Station. The launch occurred at 23:05 GMT on 26 February 1987. The launch had originally been scheduled for late 1986, but was delayed after GOES-G failed to achieve orbit. It was built by Hughes Space and Communications, based on the HS-371 satellite bus, and was the last of five GOES-D series satellites to be launched.
Following launch, GOES-7 was positioned in geostationary orbit at a longitude of 75ð West, where it underwent on-orbit testing before being activated in the GOES-EAST slot of the constellation.
Due to the loss of GOES-G, and delays in the development of the GOES-I series spacecraft, no reserve satellites were available in the late 1980s and early 1990s. After the imager on the GOES-6 satellite failed in 1989, GOES-7 was left as the only operational GOES satellite. It was moved to 98ð West to cover the whole of the continental United States. In 1992, Meteosat 3 was leased from Eumetsat to take over GOES-EAST operations, allowing GOES-8 to be moved 112ð West. When GOES-8 entered service in 1995, it replaced Meteosat 3, and GOES-7 was moved to the GOES-WEST position at 135ð West. It remained in service until its retirement from service in 1996, at which time it was moved to 95ð West. It was then transferred to Peacesat, and positioned at 175ð West until its final retirement and disposal in 2012.
It is the only satellite to have been operated as both GOES-EAST and GOES-WEST in the course of normal operations. GOES-10 has been used as both GOES-EAST and GOES-WEST, however its operations as GOES-EAST were as a backup during an outage of GOES-12, and the satellite was not moved to the GOES-EAST orbital position.
