Palapa A1, A2
Part of the Palapa program
Palapa A1 and A2 were the initial elements of Indonesia's domestic communications
satellite system. The spacecraft were identical to Canada's Anik and Western Union's Westars except for a modified parabolic reflector, enlarged to give maximum illumination of the Indonesian landmass. Operational lives for Palapa A1 and A2
ended June 1985 and January 1988, respectively.
Based on Hughes HS-333 design. 1.5 m diameter parabolic reflector with 12
transponders working through 125 Earth stations. Spin stabilized with despun antenna and feeds.
Both satellites carried 12 transponders that provided 4000 voice circuits or 12 simultaneous TV channels to the country's 6000+ inhabited islands.
