Satellites used for telecommunication relay are kept in a geostationary orbit. A satellite is said to be in such an orbit when: 1) The orbit is geosynchronous. 2) The orbit is circular. 3) The orbit lies in the plane of the Earth's equator. 4) The orbit is at an altitude of 22,236 km Select the correct answer using the codes given below:

Question

CollectorBabu · Accepted Answer

Correct Answer: 1, 2 and 3 only. Geostationary orbit is geosynchronous orbit with circular and zero inclination which is directly above the equator at an altitude of 22,236 miles Knot which is 35,786 km. This geosynchronous orbit period of satellite is similar time period of sidereal rotation period of Earth. The Geostationary satellites appear to be stationary from earth but their angular velocity is same as that of earth.
