At launch, it had a mass of 1,170 kilograms (2,580 lb), and an expected operational lifespan of seven years.
TV-SAT 1 or TVSAT-1 was a West German communications satellite, which was to have been operated by Deutsche Bundespost. It was intended to provide television broadcast services to Europe, but it failed before entering service. It was built by Aérospatiale, was based on the Spacebus 300 satellite bus, and carried five Ku-band transponders. At launch it had a mass of 2,144 kg (4,727 lb), and an expected operational lifespan of eight years.
GOES-8, known as GOES-I before becoming operational, was an American weather satellite, which formed part of the US National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite system. It was launched in 1994, and operated until 2004 when it was retired and boosted to a graveyard orbit. At launch, the satellite had a mass of 2,105 kilograms (4,641 lb), and an expected operational lifespan of three or five years. It was built by Space Systems/Loral, based on the LS-1300 satellite bus, and was the first of five GOES-I series satellites to be launched.
Orion 3 was an American spacecraft which was intended for use by Orion Network Systems, as a geostationary communications satellite. It was to have been positioned in geostationary orbit at a longitude of 139° East, from where it was to have provided communications services to Asia and Oceania. Due to a malfunction during launch, it was instead delivered to a useless low Earth orbit.
TDRS-6, known before launch as TDRS-F, is an American communications satellite, of first generation, which is operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by TRW, and is based on a custom satellite bus which was used for all seven first generation TDRS satellites.
TDRS-7, known before launch as TDRS-G, is an American communications satellite, of first generation, which is operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by TRW as a replacement for TDRS-B, which had been lost in the Challenger accident, and was the last first generation TDRS satellite to be launched.
TDRS-9, known before launch as TDRS-I, was an American communications satellite which was operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by the Boeing Satellite Development Center, formerly Hughes Space and Communications, and was based on the BSS-601 satellite bus. It was the second Advanced TDRS, or second-generation Tracking and Data Relay Satellite, to be launched.
Galaxy 11 is an American geostationary communications satellite which is operated by Intelsat. It is located in geostationary orbit at a longitude of 32.8 degrees east, where it serves as a backup to the Intelsat 802 spacecraft. It was originally operated at 99° West and later spent most of its operational life at 91° West, from where it was used to provide communications services to Brazil and North America.
Hot Bird 7 was a communications satellite that lost in a launch failure in 2002. Intended for operation by Eutelsat, it was to have provided direct-to-home broadcasting services from geostationary orbit as part of Eutelsat's Hot Bird constellation at a longitude of 13° East. Hot Bird 7 was intended to replace the Hot Bird 3 satellite, which had been launched in 1997.
INSAT-4CR was a communications satellite operated by ISRO as part of the Indian National Satellite System. Launched in September 2007, it replaced the INSAT-4C satellite which had been lost in a launch failure the previous year. The satellite was initially stationed in geostationary orbit at a longitude of 74 degrees east, with expected operational life of at least ten years, however this may have been reduced by the underperformance of the Geosynchronous Satellite Launch Vehicle which placed it into orbit. INSAT-4CR is planned to be replaced by GSAT-31, which was launched on February 6, 2019.
This page includes a list of satellite buses, of which multiple similar artificial satellites have been, or are being, built to the same model of structural frame, propulsion, spacecraft power and intra-spacecraft communication. Only commercially available buses are included, thus excluding series-produced proprietary satellites operated only by their makers.
INSAT-1A was an Indian communications satellite which formed part of the Indian National Satellite System. Launched in 1982, it was operated in geostationary orbit at a longitude of 74° east. Following a series of failures, the satellite was abandoned in September 1982, less than six months into a seven-year mission.
Intelsat II was a series of four communications satellites operated by Intelsat which were launched in 1966 and 1967. Built by the Hughes Aircraft Company, the Intelsat II series was a follow-up to the Intelsat I series, of which only one satellite was launched.
Inmarsat-4A F4, also known as Alphasat and Inmarsat-XL, is a large geostationary communications I-4 satellite operated by United Kingdom-based Inmarsat in partnership with the European Space Agency. Launched in 2013, it is used to provide mobile communications to Africa and parts of Europe and Asia.
INSAT-4B was an Indian communications satellite which forms part of the Indian National Satellite System. Launched in 2007, it was placed in geostationary orbit at a longitude of 93.48° East.
INSAT-1D was 4th and the concluding multipurpose geostationary satellite of the INSAT-1 (first-generation seven-year responsibility for the operation of the INSAT space segment.
Intelsat 802 was a communications satellite operated by Intelsat. Launched in 1997 it was operated in geostationary orbit at a longitude of 174 degrees west for around fourteen years.
NSS-5 is a communications satellite operated by Intelsat and after by SES World Skies. Launched in 1997 it was operated in geostationary orbit at a longitude of 50.5 degrees east for around 14 years.
Intelsat 804 was a communications satellite operated by Intelsat. Launched in 1997 it was operated in geostationary orbit at a longitude of 44 degrees east for around 8 years.
STENTOR was a French communications satellite which was lost in a launch failure in 2002. Intended for operation by CNES, France Telecom, and Direction générale de l'armement (DGA). To validate, in flight, advanced technologies which would be integrated in the next generation of telecommunications spacecraft. It will also demonstrate new telecommunications services, including broadband and multimedia transmissions to small user terminals.
