SATELLITE COMMUNICATION
A satellite is an object that moves around (orbits) a larger object. Satellite communication, in telecommunication is the use of artificial satellites to provide communication links between various points on Earth. Approximately 2,000 artificial satellites orbiting the Earth relay analogue and digital signals carrying voice, video and data from one or many locations worldwide. For instance, radio wave signals are beamed or transmitted from an earth-based station towards the satellite orbiting in space; the satellite amplifies the signal and retransmits it back to the receiver’s antenna present on the earth’s surface.
