An object moving in a circular orbit at a constant speed has a changing velocity. Dynamic Doppler compensation, where the frequency of a signal is changed progressively during transmission, is used so the satellite receives a constant frequency signal. A geostationary satellite orbits the earth with a velocity of 3.07km/s. Calculate its speed if it takes 24 hours to revolve around the earth. A satellite orbiting about the earth moves in a circular motion at a constant speed and at fixed height by moving with a tangential velocity that allows it to fall at the same rate at which the earth curves.

A satellite is moving with a constant speed ‘V’ in a cirular orbit about the earth. Since the satellite is in orbit, it is always feeling a constant force of gravity. It is moving in a circle.
