Answers
Answer:
A ground segment consists of all the ground-based elements of a spacecraft 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 ground segment are:
Ground (or Earth) stations, which provide radio interfaces with spacecraft[2]:142
Mission control (or operations) centers, from which spacecraft are managed[3]:20
Ground networks, which connect the other ground elements to one another[2]:142[4]
Remote terminals, used by support personnel[2]:142
Spacecraft integration and test facilities
Launch facilities[3]:21
A simplified spacecraft system. Dotted orange arrows denote radio links; solid black arrows denote ground network links. (User terminals typically rely on only one of the indicated paths for access to space-segment resources.)
These elements are present in nearly all space missions, whether commercial, military, or scientific. They may be located together or separated geographically, and they may be operated by different parties.[5][6]:25 Some elements may support multiple spacecraft simultaneously.[7]:480,481
