Ground station
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.
