equatorial plane of the earth such that a satellite appears to hover over a fixed point on the equator. The period of revolution is equal to the period of rotation of the earth with respect to the stars‚ or 23 hours 56 minutes 4.1 seconds‚ and thus by Kepler’s third law the orbital radius is 42‚164 km. Taking into account the radius of the earth‚ the height of a satellite above the equator is 35‚786 km. Clarke observed that only three satellites would be required to provide communications
