When a ground station successfully transmits radio waves to a spacecraft (or vice versa), it establishes a telecommunications link.
Article 1 § III of the International Telecommunication Union (ITU) Radio Regulations describes various types of stationary and mobile ground stations, and their interrelationships.
Teleports may provide various broadcasting services among other telecommunications functions,[4] such as uploading computer programs or issuing commands over an uplink to a satellite.
[citation needed] In Federal Standard 1037C, the United States General Services Administration defined an Earth terminal complex as the assemblage of equipment and facilities necessary to integrate an Earth terminal (ground station) into a telecommunications network.
A network is established to provide dedicated support to a specific mission, function, program or organization.
