How do Satellites Work
Stations on Earth want to communicate through 
radio broadcast but are too far away to use conventional 
means.

The two stations can use a satellite as a relay station for  their communication
One Earth Station sends a transmission to the 
satellite.  This is called a Uplink.

The satellite Transponder converts the signal and 
sends it down to the second earth station.  This is called
Downlink.
Importance  of Satellites 

The advantages of satellite communication over 
terrestrial communication are:
§The coverage area of a satellite greatly exceeds that of a terrestrial system.
§Transmission cost of a satellite is independent of the
distance from the centre of the coverage area.
§Satellite to Satellite communication is very precise.
§Higher Bandwidths are available for use
