Abstract
Communication via satellite has come to stay. This new mode of satellite communications is being used not only for international links but also for national communication networks. The tendency is to use more and more powerful and complicated satellites in space so that ground segment cost could be reduced. Setting up a Satellite Communication Earth Station calls for careful planning and systems engineering effort. Trade offs between antenna size, output of high power amplifier and noise temperature of low noise amplifier are essential to have an earth station that meets international specifications for high quality communications with minimum cost. This paper gives some of the systems approaches for setting up an earth station. The site selection, station layout and power supply requirements have been considered. Spare parts and maintenance strategy of not only the station equipments but also of test instruments have been reviewed. Future system concepts along with possible new approaches have been presented.
