Anik C1 (also called Telesat-9 or Nahuel I1 or Brasil 1T) is a television satellite in the Anik series of the Canadian satellite operator Telesat Canada .
Development and construction
The deal with Hughes was signed in 1978. The Anik C1, developed by Hughes Aircraft on the basis of the HS 376 satellite bus , weighed 1238 kg (with McDonnell Douglas payload assist module (PAM) to be injected into orbit), 562 kg in orbit (99 kg of which was fuel) and was for one operating time designed for eight years. The satellite has a cylindrical shape with a size of 2.16 m in diameter and a height of 2.82 m at launch. By extending the inner part of the cylinder and the antenna, it has a height of 6.43 m in orbit. The energy is supplied by solar cells on the outside of both cylinder parts.
history
The satellite was launched on April 12, 1985 at 13:59:05 UTC with the Space Shuttle Discovery during the STS-51-D mission . It was placed in low earth orbit by the shuttle the following day and put itself into geostationary orbit at 107 ° West with the PAM.
It was sold several times, renamed and moved to a new position (109 ° West, 72 ° West, 118 ° West, 106 ° West). After a few years it was sold to the Argentine Paracomsat and in 1997 back to Telesat. In 2000 it was bought by Loral Skynet do Brasil , renamed Brasil 1T and moved to a position of 63 ° West. It was finally deactivated on May 5, 2003 and sent into cemetery orbit .
reception
The satellite could be received in North and South America . The transmission took place in the Ku band .
