This artificial satellite is positioned in space to facilitate the communication among the various points on the earth.
General structure of satellite communication system.
The first edition was a response to a request by many friends and associates for a basic and clear book that provides newcomers with an accessible way to gain knowledge and become productive.
In general terms a satellite is a smaller object that revolves around a larger object in space.
Satellite communication satellite communication how satellites work.
It consists of one or several satellites organised into constellation.
A satellite has to withstand the shock of being accelerated during launch up to the.
A communications satellite is in a geostationary equatorial orbit with a period of 24 h.
For instance communication can be possible using light in an optical communication system radio signals can be used to communicate in the radio communication system and telecommunication is used for communication using satellite.
A satellite is basically a self contained communications system with the ability to receive signals from earth and to retransmit those signals back with the use of a transponder an integrated receiver and transmitter of radio signals.
We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel.
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.
Types of satellite communication.
This article discusses an overview of the satellite communication system.
In other words it is nothing but sending receiving and processing of information.

A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder.
Let us now look into the basic structure of a satellite communication system.
Satellite communication system is a mode of communication which uses the artificial satellite for communication.
Elements of satellite communication the basic element of satellite communication are earth station terrestrial system and users the basic structure of a satellite communication are shown in the.
It is composed of three units.
Introduction to satellite communication is designed to meet the needs of working professionals and students.
Here in this post a brief idea of elements of satellite communication system advantages and disadvantages of 6 4 ghz frequency allocation etc.
There are about 2 000 communications satellites.
The uplink frequencies 5 9 6 4 ghz are used for t n from the earth station to the satellite and down link frequencies 3 7 4 2ghz.
