Ensuring Communications From Space To Ground - Near Earth To Interstellar Space

General Dynamics has provided the critical communications link between Earth and space since the mid-1950s. In all, General Dynamics has produced over 400 space transponders including over 150 Deep Space, Near Earth and Tracking and Data Relay Satellite System (TDRSS) transponders and transceivers for NASA missions. Examples include the Voyager spacecraft, launched in 1977, which carries two Deep Space Transponders that are still functioning, and the two first generation TDRSS user transponders flying on the Hubble Space Telescope that continue to operate trouble free after more than 19 years of service in space.
