Tracking and Relay Data Satellite (TDRS) Project

TDRS Sattelite

The Tracking and Data Relay Satellite (TDRS) Project is providing follow-on and replacement spacecraft necessary to maintain and expand the Space Network.

The NASA Space Network consists of the on-orbit telecommunications TDRS satellites, placed in geosynchronous orbit, and the associated TDRS ground stations, located in White Sands, New Mexico and Guam. The TDRS constellation is capable of providing nearly continuous high bandwidth (S, Ku, and Ka band) telecommunications services for expandable launch vehicles and user spacecraft in low Earth orbit. The TDRS System is a basic agency capability and a critical national resource.

As a vital information pipeline for space-based research and exploration ambitions, TDRS fulfills NASA’s broadest communication demands. Now into its third operational decade, its legacy of communications excellence is storied and grand. It has provided critical support to NASA’s human spaceflight endeavors from the early beginning of the Space Shuttle Program through ongoing International Space Station support today. TDRS provides communication support to many different science missions, as well as a number of launch vehicles. The SN provides the ability to conduct real-time operations, for example satellite health monitoring and commanding, and to deliver high volumes of science data with low-latency.

Review Status: The TDRS Project was established in 1973. Reviews for TDRS L and TDRS M are ongoing.
