satellite Communication
The use of artificial satellites to provide communication links between various points on Earth is known as satellite communication in telecommunications. In the global telecommunications system, satellite communications are critical. Across 2,000 artificial satellites orbit the Earth, relaying analogue and digital signals delivering audio, video, and data to and from one or more sites around the world.
The ground segment, which includes stationary or mobile transmission, reception, and ancillary equipment, and the space segment, which includes the satellite itself, are the two fundamental components of satellite communication. The transmission or uplinking of a signal from an Earth station to a satellite is typical of a satellite connection. The signal is subsequently received, amplified, and retransmitted by the satellite to Earth, where it is received and amplified by Earth stations.
