It was placed in a geosynchronous orbit at 96 degrees W and was launched with the main communications reflector and the outer cylinder stowed, a configuration that makes it possible to launch with expendable rocket boosters of from the space shuttle. The spacecraft was 7 feet, 1 inch (2.16 meters) in diameter. Height with antennas and the telescoping solar panel deployed was 22 feet, 5 inches (6.84 meters). Like their predecessor satellites, the Telstar 3 satellites operated at 6/4 GHz (C-band). Simultaneous long distance telephone call capacity was 21,600. The satellite furnished voice, video, and high speed data services to the continental US, Hawaii, Alaska and Puerto Rico.
