A ground segment consists of all the ground-based elements of a space system used by operators and support personnel, as opposed to the space segment and user segment. [1] [2]: 1 The ground segment enables management of a spacecraft, and distribution of payload data and telemetry among interested parties on the ground. The primary elements of a ...
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.
The space segment of an artificial satellite system is one of its three operational components (the others being the user and ground segments). It comprises the satellite or satellite constellation and the uplink and downlink satellite links. [1] The overall design of the payload, satellite, ground segment, and end-to-end system is a complex ...
The Network Control Center Data System (NCCDS) is an element of the SN ground segment. [3] Collocated with the White Sands Tracking and Data Relay Satellite System, the NCCDS is the operations control facility for the network. It schedules most Space Network elements and supporting elements and provides interfaces for planning, acquisition ...
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.
The ground terminal segment consists of equipment and resident personnel at existing satellite communication stations. The satellites are controlled by the 10th Space Operations Squadron ( Space Delta 8 ) located at the Naval Base Ventura County , Point Mugu , California .
The UHF transmitting antenna of DORIS ground station at Dionysos, Greece. The ground segment includes about 50-60 ground stations, equally distributed over the Earth and ensure a good coverage for orbit determination. For the installation of a beacon only electricity is required because the station only emits a signal but does not receive any ...
The system's orbit and signal accuracy is controlled by a ground segment consisting of: Two ground control centres, located in Oberpfaffenhofen and Fucino for Satellite and Mission Control; Seven telemetry, tracking & control (TT&C) stations, located in Kiruna, 2x Kourou, Nouméa, Réunion, Redu and Papeete
