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 Mercury Space Flight Network (MSFN) was completed in 1961, and consisted of 18 ground tracking stations and two ships in the Atlantic and Indian Oceans to close gaps between ground stations.

This site was designated the Pilotless Aircraft Research Station and conducted high-speed aerodynamic research to supplement wind tunnel and laboratory investigations into the problems of flight. In 1958, Congress established NASA, which absorbed Langley Research Center and other NACA field centers and research facilities.
The MILA tracking station was installed in 1966 as part of a worldwide network of 17 ground-based tracking stations to support the Apollo program. It was first used for a Saturn 1B test launch in July 1966. Training consoles were installed shortly thereafter to train engineers from the Johnson Space Center. [2]
STS-43, the ninth mission for Space Shuttle Atlantis, was a nine-day mission whose primary goal was launching the TDRS-E satellite (TDRS-5). The flight also tested an advanced heatpipe radiator for potential use on the then-future space station and conducted a variety of medical and materials science investigations.
The Goldstone Deep Space Communications Complex (GDSCC), commonly called the Goldstone Observatory, is a satellite ground station located in Fort Irwin [1] in the U.S. state of California. Operated by NASA's Jet Propulsion Laboratory (JPL), its main purpose is to track and communicate with interplanetary space missions.
Hernando is a census-designated place in Citrus County, Florida, United States. The population was 9,284 at the 2020 census, up from 9,054 at the 2010 census. [4] At one time it was a city but it was disincorporated in the 1970s. It is part of the Homosassa Springs, Florida Metropolitan Statistical Area.
