Satellite Communication System Frequency

A satellite has to withstand the shock of being accelerated during launch up to the.

Satellite communication system frequency.

Inmarsat providing communications at sea land and air. Difficult to provide repairing activities if any problem occurs in a satellite system. A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder. There can be congestion of frequencies.

Applications of satellite communication. Propagation delay of satellite systems is more than that of conventional terrestrial systems. Satellite communication plays a vital role in our daily life. 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.

Satellite vsat communication is split up in to four radio frequency rf bands that commercial communication and military satellites operate within. Free space loss is more. There are about 2 000 communications satellites. For real time communications the shorter the transmission delay the better will be the communication system.

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. 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. 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.
