To launch an artificial satellite in space, multi-stage rockets are used. It raises the satellite to a predetermined height, projects it in the right direction with a velocity which enables it to revolve around the Earth. This velocity is called the escape velocity. Escape velo..

Communication satellites are normally geostationary satellites. They have devices called transponder which receive signals from an earth station and transmit them in different directions. The signals in the form of electromagnetic radiation are transmitted from the earth station..
