General structure of satellite communication system.

A communications satellite is in a geostationary equatorial orbit with a period of 24 h. Block diagram of satellite communication system satellite communication system block diagram. 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. This article discusses an overview of the satellite communication system.

Introduction to satellite communication is designed to meet the needs of working professionals and students. The spin rate ω s about its axis of symmetry is 1 rpm and the moment of inertia about the spin axis is 550 kg m 2 the moment of inertia about transverse axes through the mass center g is 225 kg m 2 if the spin axis is initially pointed toward the earth calculate the magnitude and direction of. We know that communication refers to the exchange sharing of information between two or more entities through any medium or channel. It is composed of three units.

This artificial satellite is positioned in space to facilitate the communication among the various points on the earth. It consists of one or several satellites organised into constellation. 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. There are about 2 000 communications satellites.

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. Types of satellite communication. A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder. For example moon is a natural satellite of earth.

In general terms a satellite is a smaller object that revolves around a larger object in space. 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. 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. A satellite has to withstand the shock of being accelerated during launch up to the.

Let us now look into the basic structure of a satellite communication system. In other words it is nothing but sending receiving and processing of information. The space station is the segment of the satellite communication system that is carried to the outer space and set to revolve the earth in a pre defined orbit.
