Satellite Communication is a mode of Communication of signals between Transmitter and Receiver through Satellite . The Satellite Communication is like Line of Sight  Communication .The basic principle of satellite communication is shown in fig(Page 13). A beam of modulated microwave from earthstation transmitter is sent towards the satellite (uplink) which receives the signal amplifies it and returns to earth’s stationary receiver (Down Link). At a different frequency to avoid interference between uplink and downlink .The signal receive is weak which may be amplified before Telecast.

Remote Sensing It is a phenomenon in which with the help of Geo  Stationary Satellite about the earth’s geographic  parameter weather forecasting about the minerals are detected.
