The Importance of Satellite Communication and ICT

The function of an earth satellite station is to transmit and receive information frequency through microwave signals of a certain frequency. It has a large parabolic disc aerial. A communication satellite will amplify these microwave signals, convert them to another frequency and transmit them to other earth satellite stations. As the world becomes more sophisticated more modern communication methods and devices are introduced to the market.

An artificial satellite is a spacecraft placed in orbit around the Earth or other planets. The electrical power required by satellite is provided by panels of solar cells and small nuclear reactors.

Satellites

Satellites are kept in the correct position by small rocket motors called thrusters. They orbit with their disc aerials pointing to Earth. When the thrusters run out of fuel, the satellite eventually drifts out of position and becomes unusable. Satellites are equipped with radio transmitters, radio receivers and electronic circuits for storing data.

Communication satellite provide services such as relaying telephone conversations, transmitting television broadcasts around the world, sending computer data between relay stations on different continents and facsimile transmission. Information is transmitted using microwaves.

Microwave signals

Microwave signals are used in satellite communication because they can travel far without being scattered by particles in the atmosphere and have very high frequencies in the atmosphere and have very high frequencies. They are also not reflected by the ionosphere. A satellite communication system consists of two systems: a) earth satellite stations b) communication satellites that occupy a special orbit called geostationary orbit.
