Intelsat VA F-11, then named Intelsat 511, was a communications satellite operated by Intelsat. Launched in 1985, it was the eleventh of fifteen Intelsat V satellites to be launched. The Intelsat VA series was constructed by Ford Aerospace, based on the Intelsat VA satellite bus. Intelsat VA F-11 was part of an advanced series of satellites designed to provide greater telecommunications capacity for Intelsat's global network.
The satellite was box-shaped, measuring 1.66 by 2.1 by 1.77 metres; solar arrays spanned 15.9 metres tip to tip. The arrays, supplemented by nickel-hydrogen batteries during eclipse, provided 1800 watts of power at mission onset, approximately 1280 watts at the end of its seven-year design life. The payload housed 26 C-band and 6 Ku-band transponders. It could accommodate 15,000 two-way voice circuits and two TV channels simultaneously. It also provided maritime communications for ships at sea. [5]
The satellite was successfully launched into space on 30 June 1985, at 00:44:00 UTC, by means of an Atlas G-Centaur-D1AR vehicle from the Cape Canaveral Air Force Station, Florida, United States. It had a launch mass of 1981 kg. [4] The satellite was deactivated in August 2003.
The Communications Technology Satellite (CTS), known as Hermes, was an experimental high-power direct broadcast communications satellite. It was a joint effort of Canadian Department of Communications, who designed and built the satellite, NASA who tested, launched and operated the satellite, and European Space Agency (ESA) who provided the 1200 watts solar panels and other devices. The three agencies shared the satellite and the data from the experiments.
TDRS-3 , known before launch as TDRS-C, 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.
Kosmos 165, also known as DS-P1-Yu No.11 was a radar calibration target satellite which was used by the Soviet Union for tests of anti-ballistic missiles. It was a 400 kilograms (880 lb) spacecraft, which was built by the Yuzhnoye Design Office, and launched in 1967 as part of the Dnepropetrovsk Sputnik programme.
Kosmos 14, also known as Omega No.1, was a satellite which was launched by the Soviet Union in 1963. It was an Omega satellite, derived from the Dnepropetrovsk Sputnik series.
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.
Intelsat III F-2 was a communications satellite operated by Intelsat. Launched in 1968 it was operated in geostationary orbit at a longitude of 24 degrees west for around eighteen months.
Intelsat III F-3 was a geostationary communications satellite operated by Intelsat. Launched in 1969 it was intended for operations over the Pacific Ocean; however, it spent most of its service life over the Indian Ocean at a longitude of 63 degrees east.
Intelsat III F-6 was a communications satellite owned by Intelsat. The satellite had an estimated useful life of 5 years.
Intelsat III F-8 was a communications satellite owned by Intelsat. The satellite had an estimated useful life of 5 years.
Intelsat IV F-4 was a geostationary communication satellite built by Hughes, it was owned by Intelsat. The satellite was based on the HS-312 platform and its estimated useful life was 7 years.
Intelsat IV F-5 was a geostationary communication satellite built by Hughes, it was owned by Intelsat. The satellite was based on the HS-312 platform and its estimated useful life was 7 years.
Intelsat V F-1 was a geostationary communications satellite built by Ford Aerospace, it was owned by COMSAT. Launched in 1981, it was the second of fifteen Intelsat V satellites to be launched. The satellite was based on the Intelsat V platform and its estimated useful life was seven years.
Intelsat V F-2, then named Intelsat 502, was a communications satellite operated by COMSAT. Launched in 1980, it was the first of fifteen Intelsat V satellites to be launched. The Intelsat V series was constructed by Ford Aerospace, based on the Intelsat V satellite bus. Intelsat V F-2 was part of an advanced series of satellites designed to provide greater telecommunications capacity for INTELSAT's global network.
Intelsat 510, previously named Intelsat VA F-10, was a communications satellite operated by Intelsat. Launched in 1985, it was the tenth of fifteen Intelsat V satellites to be launched.
