artificial satellite communication

. A good quality service can be continuously ensured by a global operational satellite system. Thus, communication satellites would give a valuable service in addition to the submarine cable and high frequency radio systems. Geostationary communication s..

Communication Satellites - 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 electro..

Satellites - The moon is a natural satellite of the Earth. We now have a number of artificial satellites (man-made) revolving around the Eart..

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. E..

The satellite communication is costly because of the limited life of a satellite. A geosynchronous satellite using high gain antenna requires close control of both its position and altitude. The position and altitude control rockets require fuel that has to ..
