Satellite Communication System Frequency

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.

Satellite communication system frequency. Difficult to provide repairing activities if any problem occurs in a satellite system. There are about 2 000 communications satellites. A satellite has to withstand the shock of being accelerated during launch up to the. Satellite communication plays a vital role in our daily life.

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. Free space loss is more. Applications of satellite communication. For real time communications the shorter the transmission delay the better will be the communication system.

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. A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder. Satellite communication satellite communication how satellites work. Satellite vsat communication is split up in to four radio frequency rf bands that commercial communication and military satellites operate within.

Global positioning system gps carriers and also satellite mobile phones such as iridium. Propagation delay of satellite systems is more than that of conventional terrestrial systems. 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.
