Geosynchronous satellites were proposed by Arthur C Clarke, the Science Fiction author, in 1945 and his speculative article was published in Wireless World Magazine in the UK. The satellite has an orbit time of 24 Hours so that it appears to remain fixed in space.The geostationary orbit is approximately 23,000 miles above the Earth and is a very crowded area since many countries have their satellites there. The satellite are entirely powered by solar panels generating 5 to 6 Kilo Watts of power. This electricity is used to receive microwave signals beamed to them by Earth Stations and then relayed back to Earth by the on board microwave transmitters.The reception footprint of the satellite can cover whole countries and is a very economical way to distribute TV signals to your chosen reception area.
Communication satellites are lifted into orbit by rockets.

The purpose for having communication satellites in space, is by providing telecommunication throughout the world. Communication satellites are mostly used for mobile phone signals, weather tracking, and broadcasting television programs.
communication satellites, astronomy, navigation, etc.
Yes, they are
The ionosphere
radios,satellites, satellites phones,ham radio are the various communication facilities during disasters
The different artificial satellites launched are Low Earth Orbiting Satellites for Remote sensing, Medium Earth Orbiting Satellites like GPS , Geo Stationary Orbiting Satellites for Communication and Molnia Satellites again for Communication. These are the different artificial Satellite orbiting the Planet Earth.
Satellites, can either be natural satellites (for example; Earth's moon), or man made satellites (for example; communication satellites).
The purpose of communications satellites are to provide telecommunication for companies around the world. In addition, communication satellites are also used for mobile applications such as communication to ships, vehicles, and planes.
