Telstar 401



Telstar 401 was an AT+T geostationary, communications spacecraft launched by an Atlas 2AS rocket from Cape Canaveral. It was the first of AT+T's next generation of broadcast video and data-communications satellites. In addition to providing hybrid C- and Ku-band transmissions, the Telstar 4 satellites could support digital compression and featured 50-state broadcast coverage, plus Puerto Rico and the US Virgin Islands. It was placed in a geosynchronous orbit at 97 degrees W.

Telstar 401's telemetry and communications abruptly stopped early morning on January 11, 1997. AT+T petitioned the FCC to move Telstar 302 to Telstar 401's orbital slot to provide temporary transponder capacity for customers.
