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.
TDRS-A was the first of TDRSS multiple satellite tracking system. The system is a concept utilizing communication satellite technology that improves and economizes the satellite tracking and telemetry operations. The base three geosynchronous satellites (one a standby) track and receive data from satellites for relay to a ground station. The ...
Location of TDRS as of 26 May 2020 Location of TDRS as of March 2019. This is a list of Tracking and Data Relay Satellites.TDRS spacecraft are all in geostationary orbit and are operated by the United States National Aeronautics and Space Administration, and are used for communication between NASA facilities and spacecraft, [1] including the Space Shuttle, Hubble Space Telescope, and ...
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 Network Control Center Data System (NCCDS) is an element of the SN ground segment. [3] Collocated with the White Sands Tracking and Data Relay Satellite System, the NCCDS is the operations control facility for the network. It schedules most Space Network elements and supporting elements and provides interfaces for planning, acquisition ...
Diego Garcia Station (DGS), Diego Garcia, BIOT; callsign REEF. The Diego Garcia Station has two sides (as of 2010) to provide enhanced tracking for the Satellite Control Network users. This site also includes a GPS Ground Antenna site. Guam Tracking Station (GTS), Guam; callsign GUAM. The Guam Tracking Station has two sides (one ARTS and one ...
Specifically, NASA Wallops has been leading two range technology development projects: the Autonomous Flight Safety System (AFSS) and the Low Cost TDRSS Transceiver (LCT2). AFSS is a project to develop an autonomous on-board system that could augment or replace traditional ground-commanded Range Safety flight termination systems.
