Digital slave worked by receiving primary tracking data from the NASA Minitrack network of stations. The computer would then issue antenna-pointing commands to control the antenna. The third tracking method was a continuous-wave radar subsystem. Radar was not suitable for acquisition of the satellite, but once Echo was acquired by optical, or ...
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.

It uses a number of different dishes scattered around the globe. The antennas must be able to move fast for tracking of objects in low Earth orbit (LEO). The NEN and Space Network (SN) combined were previously referred to as the Spaceflight Tracking and Data Network (STDN). [1]
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 ...
COSMIC maintains a library of computer programs from NASA and other government agencies and sells them at a fraction of the cost of developing a new program. NASA Structural Analysis Computer Software was inducted into the Space Foundation Space Technology Hall of Fame in 1988. [7] [27] [29] [41] [42] [43]
