Satellite having the same orbital period as the period of rotation ofthe earth about its own axis is known as geostationary satellite.Geostationary satellites are located exactly above the earth’s equator and revolve around the earth in a circular orbit. Their revolution speed and direction (west to east) are exactly same as that of the earth, which makes it look stationary from the earth’s surface. The exact altitude of these satellites above the equator is approximately 36,000 Kilometers (22369 Miles). The term geostationary stems from the fact that this kind of satellite looks practically stationary in the sky when someone on the earth’s surface observes it. A geostationary satellite’s orbital path is called the Clarke Belt, in honour of the science fiction author Arthur C. Clarke, whom is credited with coming up with the idea.
