Class: Communications. Nation: Canada. Manufacturer: Hughes.

The satellites, act as space repeaters capable of receiving transmissions from earth stations and retransmitting them to other earth stations in Canada. The antenna coverage of the satellite provides the capability of serving virtually all of Canada. Each satellite had 12 RF channels each capable of transmitting a color television signal or up to 900 one-way voice channels.

Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).


10 October 1974 Westar 2 Program: Westar. Launch Site: Cape Canaveral . Launch Vehicle: Delta 2914. Mass: 500 kg. Perigee: 35,895 km. Apogee: 35,910 km. Inclination: 9.5 deg.

Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).


07 May 1975 Anik A3 (Telesat 3) Program: Anik. Launch Site: Cape Canaveral . Launch Vehicle: Delta 2914. Mass: 286 kg. Perigee: 35,845 km. Apogee: 35,851 km. Inclination: 9.0 deg.

Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).


08 July 1976 Palapa 1 Program: Palapa. Launch Site: Cape Canaveral . Launch Vehicle: Delta 2914. Mass: 300 kg. Perigee: 35,818 km. Apogee: 35,852 km. Inclination: 8.6 deg.

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 Wasters 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.
