Satellite Based Communication System

When information is transmitted through a satellite it is called Satellite based communication. Satellites are launched into space on rockets and they are put in orbit. Different satellites carry out different jobs such as weather forecasting and finding accurate locations.

Communication satellites are usually radio relay stations and are referred to as COMSATs. The most important feature of a communication satellite is the transponder.

Transponder is nothing but an automatic device that receives, amplifies, and retransmits a signal on a different frequency. Genrally, a satellite has many transponders.
