What is a geostationary statellite? What are the basic requirements for such a satellite? |
|
Answer» It is that satellite which appears to be at a fixed position at a definite height to an observer on earth. Essential conditions for geostationary satellites are as follows: 1. A geostationary satellite should be at a height nearly 36000 km above the equator of earth. Its period of revolution around the earth should be the same as that of earth about its axis i.e. exactly 24 hours. 3. It should revolve in an orbit concentric and coplaner with the equatorial plane. 4. Its sense of rotation should be the same as that of the earth about its own axis i.e. from west to east. Its orbital velocity is nearly 3-1 km/s. |
