Intelsat I

Encyclopedia : I : IN : INT : Intelsat I

Intelsat I (nicknamed Early Bird) was the first commercial communications satellite to be placed in geosynchronous orbit on April 6, 1965. Built by the Space and Communications Group of Hughes Aircraft Company, later Hughes Space and Communications Company, and now Boeing Satellite Systems, it was built for COMSAT, which activated it June 28. It was based on the satellite Hughes had built for NASA to demonstrate that communications from synchronous orbit was feasible.

Originally slated to operate for eighteen months, Early Bird was in active service for four years, being deactivated in January 1969, although it was briefly activated in June of that year to serve the Apollo 11 flight when the Atlantic Intelsat satellite failed. It was deactivated again in August 1969 and has been inactive since that time (except for a brief reactivation in 1990 to commemorate its 25th launch anniversary), although it remains in orbit.

The Early Bird satellite was the first to provide direct and nearly instantaneous contact between Europe and North America, handling television, telephone and fascimile transmissions. It was fairly small, measuring nearly 2.5 x 2.0 feet and weighing 76 lb.
