) use a similar mechanism. In the case of intercontinental telecommunication, two or more satellites are linked together. High frequency radio and submarine cable systems have been widely used for long- distance overseas telecommunications. The high frequency band from 3 MHz to 30 MHz has..

For global communication, a communication satellite should move..

The area of the Earth from which a satellite is visible increases with the altitude. So, satellites at higher altitudes give larger coverage. At altitudes below 10,000 km, the number of satellites required for global coverage would be excessive. At altitudes above 20,0..

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..
