Explanation:
Detailed explanation-1: -The transmission of signal from first earth station to satellite through a channel is called as uplink. Similarly, the transmission of signal from satellite to second earth station through a channel is called as downlink.
Detailed explanation-2: -There are three types of communication services that satellites provide: telecommunications, broadcasting, and data communications.
Detailed explanation-3: -The equatorial ellipticity of the earth causes geostationary satellites to drift slowly along the orbit, to one of two stable points, at 75°E and 105°W. To counter this drift, an oppositely directed velocity component is imparted to the satellite by means of jets, which are pulsed once every 2 or 3 weeks.
