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 75° West, where it underwent on-orbit testing before being activated in the GOES-EAST slot of the constellation.
