Satellite Data Transmission System

It is also possible to offer discontinuous coverage using a low earth orbit satellite capable of storing data received while passing over one.

Satellite data transmission system.

A satellite carries many items of electronic equipment such as amplifiers receivers filters etc. The ground segment which consists of fixed or mobile transmission reception and ancillary equipment and the space segment which primarily is the satellite itself. The programming source the broadcast center the satellite the satellite dish and the receiver. The present invention concerns a satellite onboard data transmission system.

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 typical satellite link involves the transmission or uplinking of a signal from an earth station to a satellite. There are five major components in a satellite system. The reason for using this orbit is that the satellite circles the earth.

Satellite communication has two main components. The iridium system has 66 satellites. A group of satellites working in concert is known as a satellite constellation two such constellations intended to provide satellite phone services primarily to remote areas are the iridium and globalstar systems. More specifically it concerns a system for sending and receiving digital telecontrol tc and telemetry tm signals inside a satellite.

Description of the prior art. Direct broadcast satellites used for transmission of satellite television signals are generally in geostationary orbit 37 000 km 23 000 mi above the earth s equator.
