A communication satellite processes the data coming from one earth station and it converts the data into another form.
The programming source the broadcast center the satellite the satellite dish and the receiver.
Satellite communications can provide communication capabilities spanning long distances and can operate under circumstances or.
It creates a communication channel between a source transmitter and a receiver at different locations on earth communications satellites are used for television telephone radio internet and military applications.
Satellite communications is the use of satellite technology in the field of communications.
For example earth is a satellite of the sun and moon is a satellite of earth.
