Anik A2



Anik A2 (Telesat 2) was a telecommunications satellite weighing approximately 272.7 kb operating in a geostationary orbit with an anticipated life of 7 years. It was approximately 1.85 m in diameter and 3.38 m in height. The satellite communications system provided for 12 rf channels, two of which were protection channels for the traffic carrying channels. Up link transmission was in 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.
