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 land mass. Operational lives for Palapa A1 and A2 ended June 1985 and January 1988, respectively. Spacecraft: Based on Hughes HS-333 design.1.5 m diameter parabolic reflector with 12 transponders working through 125 Earth stations. Spin stabilised with despun antenna and feeds. Payload: Both satellites carried 12 transponders that provided 4000 voice circuits or 12 simultaneous TV channels to the country's 6000+ inhabited islands.
