A tracking and data relay satellite (TDRS) is a type of communications satellite that forms part of the Tracking and Data Relay Satellite System (TDRSS) used by NASA and other United States government agencies for communications to and from independent "User ...
List of TDRS satellites. 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 ...
22 January 2015, 07:10:47 UTC [3] TDRS-12, known before launch as TDRS-L, is an American communications satellite operated by NASA as part of the Tracking and Data Relay Satellite System. The twelfth Tracking and Data Relay Satellite, it is the second third-generation spacecraft to be launched, following TDRS-11 in 2013.
TDRS-3. 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. [4]
14 July 1995 [2] TDRS-7, known before launch as TDRS-G, 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 as a replacement for TDRS-B, which had been lost in the Challenger accident, and was the last first generation TDRS ...
TDRS-10. TDRS-10, known before launch as TDRS-J, is an American communications satellite which is operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by the Boeing Satellite Development Center, formerly Hughes Space and Communications, and is based on the BSS-601 satellite bus. [3]
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. TDRS-11 was constructed by Boeing, and is based on the BSS-601HP satellite bus.
