Intelsat III |
Intelsat III F-4 was a geostationary communications satellite which was built by TRW. It was owned by Intelsat, a company currently based in Luxembourg. The satellite had an estimated useful life of 5 years.
The Intelsat III F-4 was part of the Intelsat III series which consisted of eight satellites, which were used for retransmission of global commercial telecommunications, including live TV.
The satellite was stabilized by rotation with a minus antenna structure (The antenna was 34 inches high). It had a hydrazine propulsion system with four propellers and four tanks, and a passive thermal control. With solar cells producing 178W peak, nine Ahr NiCd batteries. The load consisted of two transponders that used 12 watt TWTA amplifiers for multiple access, 1500 audio circuits or four TV channels. The Intelsat III F-1 was disabled due to launch vehicle failure.
The satellite was successfully launched into space on May 22, 1969, by means of a Delta M vehicle from Cape Canaveral Air Force Station in Florida, United States. It had a launch mass of 293 kg. [3]

Intelsat V F-6, then named Intelsat 506, was a communications satellite operated by COMSAT. Launched in 1983, it was the sixth 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-6 was part of an advanced series of satellites designed to provide greater telecommunications capacity for INTELSAT's global network.
Intelsat 507, previously named Intelsat V F-7, was a communications satellite operated by Intelsat. Launched in 1983, it was the seventh of fifteen Intelsat V satellites to be launched. The Intelsat V series was constructed by Ford Aerospace, based on the Intelsat-V satellite bus. It was the first satellite of the Intelsat family not to be launched by the United States.
Intelsat 508, previously named Intelsat V F-8, was a communications satellite operated by Intelsat. Launched in 1984, it was the eighth 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-8 was part of an advanced series of satellites designed to provide greater telecommunications capacity for Intelsat's global network.
Intelsat 509, previously named Intelsat V F-9, was a communications satellite operated by Intelsat. Launched in 1984, it was the ninth 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-9 was part of an advanced series of satellites designed to provide greater telecommunications capacity for Intelsat's global network. He also carried a Maritime Communications Services (MCS) package for Inmarsat. However, the launch vehicle failed to put the satellite into a useful orbit.
