Satellites , that are being put to the maximum use , are the geostationary satellites . A geostationary satellite appears to remain fixed with respect to a particular point on the Earth . For such satellites , the time period of their revolution around the Earth , which equals the time period of rotation of the Earth around its own axis ( i.e. nearly 24 hours ) .
It is these satellites that have made global audio - visual communication such a practical , and now routine , reality .
These satellites stay in the same position relative to the surface of the Earth ; hence the broadcasting station does not lose contact with the reciever .
Satellites have revolutionized communication by making worldwide telephone links and live broadcast a common occurrences and Daily feature of our life . A satellite receives a microwave signal from a ground station on the earth ( the up link ) . It's amplifiers first amplify it . Thereafter , its transmitters re - transmit the ( amplified ) signal back to a recieving station on earth at a different frequency ( the down link ) .
