TDRS Program Logo Location of TDRS as of March 2019 An unflown TDRS on display at the Steven F. Udvar-Hazy Center in Chantilly, Virginia.. The U.S. Tracking and Data Relay Satellite System (TDRSS, pronounced "T-driss") is a network of American communications satellites (each called a tracking and data relay satellite, TDRS) and ground stations used by NASA for space communications.
Use of operating frequencies near 2150 (plus or minus 150) MHz and near 14.3 (plus or minus 0.9) GHz were the initial plan. TDRSS was originally intended to support satellites with apogees below 12,000 km. Spacecraft in the TDRSS require only one communications system, since ground-based telemetry stations will be compatible with TDRSS equipment.
The DSN, as the name implies, tracks probes in deep space (more than 10,000 miles (16,000 km) from Earth), while NEN and TDRSS are used to communicate with satellites in low earth orbit. TDRSS uses a network of 10 geostationary communication satellites, and a single ground station at White Sands Test Facility. [1]
The Satellite Control Network consists of satellite control centers, tracking stations, and test facilities located around the world. Satellite Operations Centers (SOCs) are located at Schriever Space Force Base [2] near Colorado Springs, Colorado, and various other locations throughout the continental United States. These SOCs are staffed ...
Space Network (SN) is a NASA program that combines space and ground elements to support spacecraft communications in Earth vicinity. The SN Project Office at Goddard Space Flight Center (GSFC) manages the SN, which consists of: [1] The geosynchronous Tracking and Data Relay Satellites (TDRS), Supporting ground terminal systems,

The process uses two TDRSS communications relay satellites receiving the same telemetry broadcast from a satellite. The Doppler shifts experienced by both TDRS satellites can be processed using ground equipment to generate trajectory estimates without the need for onboard GPS solutions.
At that time, the Pilotless Aircraft Research Station became a separate facility, Wallops Station, operating directly under NASA Headquarters in Washington, D.C. In 1959, NASA acquired the former Naval Air Station Chincoteague , and engineering and administrative activities were moved to this location.
