Tracking and Data Relay Satellite System (TDRS)
Connecting Distant Spacecraft To Earth
The Tracking and Data Relay Satellite (TDRS) System is NASA's network of specialized communications satellites that orbit 22,300 miles above the Earth. As the name suggests, TRDS allows NASA and other agencies to communicate to and from satellites, spacecraft and the International Space Station via ground control stations on Earth. General Dynamics has supported TDRS program for 30+ years through our work in helping NASA operate, upgrade and maintain the ground system terminals.

TDRS: The Network That Enables Exploration
In addition to supporting the TDRS mission from the ground since 1983, General Dynamics is the prime contractor for NASA's Space Network Ground Segment Sustainment (SGSS) project that is modernizing all of NASA's space network ground communication systems and provides for continuous ground system technology and system upgrades for the next 25 years.
