order to collect the information and for communication. The satellite serves as a relay station between earth stations at different locations. Prof. Dr. Md.
Communications Satellites: “Bent Pipes” Mirrors and Multipoint Broadcasters satellite is essentially a space-based receiving and transmitting radio In other words it sends electromagnetic waves carrying information over distances without the use of wires
Satellite communications are comprised of 2 main components: The Satellite The satellite itself is also known as the space segment and is composed of three separate units namely the fuel system the satellite and telemetry controls and the transponder
Satellite Communications Process 1 Digital information from user arrives at a “ground station” 2 Digital signal goes into a modulator converting digital information into a modulated carrier 3 Carrier frequencyis changed (up-converted) to place it in the desired frequency range (up-link frequency band) for transmission to the satellite 4
A telecommunications satellite comprises: ?A platform(or bus): propulsion system fuel tanks batteries solar panels attitude and orbit control functions etc It is usually standardized by the manufacturer ?A payload: the equipment used to provide the service for which the satellite has been launched It is customized for a given mission
If the communication takes place between any two earth stations through a satellite then it is called as satellite communication In this communication electromagnetic waves are used as carrier signals These signals carry the information such as voice audio video or any other data between ground and space and vice-versa
