Anik A3



Telesat 3 (Anik A3) was the third domestic communications satellite launched by NASA from Cape Canaveral for the Canadian company Telesat. It weighed approximately 281 kg in a geostationary orbit with an anticipated life of seven years. It was about 1.83 m in diameter and 3.35 m high. The satellite communications system provided for 12 RF channels, two of which were protection channels for the 10 traffic carrying channels. Up-link transmission was the 5.925- to 6.425-gHz band, and the down-link operated in the 3.7- to 4.2-gHz band. Telemetry, tracking, and command functions required for satellite station keeping and positioning were also provided in those frequency bands.
