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 ...
Relay 1 launch: Delta second stage hoisted to mate it with first stage in background Relay 1 satellite under assembly (1962). Relay 1 (COSPAR satellite ID: Relay 1 1962-Beta-Upsilon 1 (62BU1)) was launched atop a Delta B rocket (355/D-15) on December 13, 1962, from LC-17A at Cape Canaveral Air Force Station. [5]
TDRS-3, known before launch as TDRS-C, is an American communications satellite, of first generation, which is operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by TRW , and is based on a custom satellite bus which was used for all seven first generation TDRS satellites.
TDRS-11, known before launch as TDRS-K, is an American communications satellite which is operated by NASA as part of the Tracking and Data Relay Satellite System. The eleventh Tracking and Data Relay Satellite is the first third-generation spacecraft. [4] TDRS-11 was constructed by Boeing, and is based on the BSS-601HP satellite bus.
TDRS-1, known before launch as TDRS-A, was an American communications satellite, operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by TRW and launched by Space Shuttle Challenger on its maiden flight, STS-6. [3]
TDRS-B was an American communications satellite, of first generation, which was to have formed part of the Tracking and Data Relay Satellite System. It was destroyed in 1986 when the Space Shuttle Challenger disintegrated 73 seconds after launch.
