Telecommunications port Ī telecommunications port - or, more commonly, teleport - is a satellite ground station that functions as a hub connecting a satellite or geocentric orbital network with a terrestrial telecommunications network, such as the Internet. A pair of ground stations are said to have a spacecraft in mutual view when the stations share simultaneous, unobstructed, line-of-sight contact with the spacecraft. It is possible for a spacecraft to communicate with more than one ground station at a time. When a spacecraft or satellite is within a ground station's line of sight, the station is said to have a view of the spacecraft (see pass). A ground station that primarily receives telemetry data, or that follows space missions, or satellites not in geostationary orbit, is called a ground tracking station, or space tracking station, or simply a tracking station. Other ground stations communicate with crewed space stations or uncrewed space probes. Specialized satellite Earth stations are used to telecommunicate with satellites - chiefly communications satellites. Article 1 § III of the International Telecommunication Union (ITU) Radio Regulations describes various types of stationary and mobile ground stations, and their interrelationships. Ground stations may have either a fixed or itinerant position. A principal telecommunications device of the ground station is the parabolic antenna. When a ground station successfully transmits radio waves to a spacecraft (or vice versa), it establishes a telecommunications link. Earth stations communicate with spacecraft by transmitting and receiving radio waves in the super high frequency (SHF) or extremely high frequency (EHF) bands (e.g. Ground stations may be located either on the surface of the Earth, or in its atmosphere. Parkes Observatory pointing toward the Moon, receiving data from Apollo 11 mission back to EarthĪ 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.
