Question
What is the angle between the equatorial plane and the orbital plane of geostationary satellite?
Solution
As we know geostationary satellite revolves from west to east direction with an equatorial plane. So, the angle between the geostationary and equatorial planes is equal to zero.

As you have learnt in the text, a geostationary satellite orbits the earth at a height of nearly 36,000 km from the surface of the earth. What is the potential due to earth’s gravity at the site of this satellite? (Take the potential energy at infinity to be zero). Mass of the earth = 6.0 × 1024 kg, radius = 6400 km

What is the angle between the equatorial plane and the orbital plane of polar satellite?
Mean solar day is the time interval between two successive noon when sun passes through zenith point (meridian). Sidereal day is the time interval between two successive transit of a distant star through the zenith point (meridian). By drawing appropriate diagram showing earth’s spin and orbital motion, show that mean solar day is four minutes longer than the sidereal day. In other words, distant stars would rise 4 minutes early every successive day.
A satellite is to be placed in equatorial geostationary orbit around earth for communication.
- Calculate height of such a satellite.
- Find out the minimum number of satellites that are needed to cover entire earth so that at least one satellites is visible from any point on the equator.
