    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.

  4. Ground segment - Wikipedia

    en.wikipedia.org/wiki/Ground_segment

    Ground station equipment may be monitored and controlled remotely. There are often backup stations from which radio contact can be maintained if there is a problem at the primary ground station which renders it unable to operate, such as a natural disaster. Such contingencies are considered in a Continuity of Operations plan.

    Parkes Observatory pointing toward the Moon, receiving data from Apollo 11 mission back to Earth. A ground station, Earth station, or Earth terminal is a terrestrial radio station designed for extraplanetary telecommunication with spacecraft (constituting part of the ground segment of the spacecraft system), or reception of radio waves from astronomical radio sources.

  6. Complementary ground component - Wikipedia

    en.wikipedia.org/wiki/Complementary_ground_component

    Complementary ground component system as part of a mobile satellite system. A complementary ground component is a terrestrial infill system for a mobile-satellite service that uses terrestrial base stations to provide connectivity in weak signal areas, such as urban areas. [1] According to EU Decision 626/2008/EC:

    en.wikipedia.org/wiki/Very-small-aperture_terminal

    A 2.5 m parabolic dish antenna for bidirectional satellite Internet access. A very-small-aperture terminal (VSAT) [1] is a two-way satellite ground station with a dish antenna that is smaller than 3.8 meters. The majority of VSAT antennas range from 75 cm to 1.2 m. Bit rates, in most cases, range from 4 kbit/s to 16 Mbit/s.
