Q. Apart from geostationary satellite orbit, some other orbits are also used for satellite communication. Which one from the following is not used for satellite communication?

Satellites can be put into elliptical orbits if they need only sometimes to be in high- or low-earth orbit, thus avoiding the need for propulsion and navigation in low-earth orbit and the expense of launching into high-earth orbit. Suppose a satellite is in an elliptical orbit, with $a = 4420$ and $b = 4416$ , and with the center of the Earth being at one of the foci of the ellipse. Assuming the Earth has a radius of about $3960$ miles, find the lowest and highest altitudes of the satellite above the Earth.

Q. Define binding energy of a satellite. Obtain an expression for the binding energy of a satellite revolving around the earth at a certain altitude.

Q. It is equally well known that a GPS satellite needs an extremely accurate clock to function correctly; it is less well known however, that GPS satellites also need to adjust for the effects of time dilation, because time passes more slowly on the satellite than it does on earth.

What is the device that determines position, time and path of objects on earth using satellites?
