Elements Of Satellite Communication System

Elements of satellite communication this consists of many earth stations on the ground and there are linked with a satellite in space.

Elements of satellite communication system.

The satellite majorly works on the solar power which is continuously received by the satellite s solar panels. The users is connected to the earth station through a terrestrial station and this network may be a telephonic switch or a well established link to a earth station. A repeater is a circuit which increases the strength of the signal it receives and retransmits it. Terrestrial system can be switch or telephone line or network.

The function of terrestrial system is to proceed the baseband signal to the earth station which are coming from the user. Satellite is powerful long distance and point to multipoint communication system. These are the following important element in the satellite communication system. The satellites are generally equipped with an antenna and transponder to facilitate the communication process.

There are broadly three major types of satellite system. Case study of internet of things in area of agriculture. The ground segment which consists of fixed or mobile transmission reception and ancillary equipment and the space segment which primarily is the satellite itself. User are located on the earth and they produces the baseband signal.

The satellite itself is also known as the space segment and is composed of three separate units namely the fuel system the satellite and telemetry controls and the transponder. A typical satellite link involves the transmission or uplinking of a signal from an earth station to a satellite. Digital satellite communication systems by oyudo richard chidiebube. To overcome disadvantage of line of sight communication which is only 45 55 km the transmitting antenna is placed on the satellite and the satellite is placed in the orbit high above the earth.

Elements of a digital satellite communication system the army s digitization initiative. Case study of internet of things. Satellite communication has two main components.
