Satellite Communication System Frequency

Propagation delay of satellite systems is more than that of conventional terrestrial systems.

Satellite communication system frequency.

Satellite communication plays a vital role in our daily life. Inmarsat providing communications at sea land and air. Free space loss is more. S band 2 4 ghz weather radar surface ship radar and some communications satellites especially those of nasa for communication with iss and space shuttle.

A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder. Applications of satellite communication. There are about 2 000 communications satellites. Global positioning system gps carriers and also satellite mobile phones such as iridium.

Satellite communication satellite communication how satellites work. These different frequency bands have separate uplink tx and downlink rx frequencies require different rf components lnb and buc and are suited to different applications. 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. As an example if a geo satellite requires 0 25 seconds for a round trip then meo satellite requires less than 0 1 seconds to complete the same trip.

There can be congestion of frequencies. Difficult to provide repairing activities if any problem occurs in a satellite system. A satellite has to withstand the shock of being accelerated during launch up to the.
