Today's planet is a large network of global communications systems, the role of satellite networks in global communications is rising unparalleled. Television, mobile, radio, internet and military communications satellites are used. The invention of satellites revolutionizes connectivity worldwide. Other feathers in satellite communication applications are GPS Navigation, Global Telephony, Interactive Video and Internet Access, Earth Imaging by Remote Sensing Satellites for Resource Tracking, Telemedicine, Tele Education, etc. Satellite communication system has entered a transition from point-to - point, high-capacity transmission trunks to low-cost multipoint-to-multipoint connectivity. Satellite Communication has served humanity in many respects, e.g. forecasting weather, storm warning, offering a wide variety of television transmission services, digital data for a multitude of business services, and most recent telephony and mobile communications. It is not shocking that satellite communication links will be used in the near future for voice and fax transmission to aircraft on international routes.
