Satellite Communication System Frequency

Free space loss is more.

Satellite communication system frequency.

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. Satellite communication plays a vital role in our daily life. A satellite has to withstand the shock of being accelerated during launch up to the. Propagation delay of satellite systems is more than that of conventional terrestrial systems.

There are about 2 000 communications satellites. 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. For real time communications the shorter the transmission delay the better will be the communication system.

Applications of satellite communication. Satellite vsat communication is split up in to four radio frequency rf bands that commercial communication and military satellites operate within. 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.

Global positioning system gps carriers and also satellite mobile phones such as iridium. Satellite communication satellite communication how satellites work. 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.
