SATELLITE COMMUNICATION
ABSTRACTThe transfer of information from source to destination i.e transmitter to receiver is called the communication. Basically communication is possible in two ways they are wire communication and the other one is wireless communication.
The satellite communication is a best example for the wire less communication.
In this paper we are first giving a brief satellite history and next why we are using satellite for communication and the orbital model. How the satellites stay in orbits and orbit types. After we are concentrating how an artificial satellite is launched. And what components required for satellite designers. And after we are giving few applications and key research challenges.
