Review on Satellite Communication Systems

ABSTRACT In the context we review worldwide Internationally communications network, satellite communications systems are very important. Satellite communications links having capacity to existing communications capabilities and provide additional alternate paths for communications traffic. Satellite links, as one of several kinds of long-distance links, interconnect switching centres located strategically around the world. Satellite Communication has worked many ways like crops prediction, whether prediction, cyclone prediction, rain prediction or any type of prediction is possible with the help of satellite communication also satellite communication provide wide range of communication services in the field of mobile communication , television , telephony, GPS  and DBS for bigger revenue generation. Now a days we are not surprise if satellite communication links may be used for voice and fax transmission to Aircraft on International routes in near future. GPS Navigation, Global telephony, Multimedia video and internet connectivity, Earth Imaging through Remote sensing satellites for resource monitoring, Telemedicine, Tele-education services etc. are other feathers in Satellite communication applications. Satellite communication system has entered transition from point-to-point high cost, high capacity trunks communication to multipoint -to-multipoint communication with low cost. Satellite Communication has moved in many steps ahead like frequency reuse, interconnecting many ground terminals spread over the world, concept of multiple spot beam communications, Laser beam-based communication through satellites and use of networks of small satellites in low earth orbit. In this paper satellite communication advancement, different application aspect present and future is discussed. Satellite communication has many application and market if we can pool our resources, come up with innovative and low-cost solutions for world community. Keywords: Satellite communication, GPS, television, broadcast, radio, mobile communication. Cite this Article: Mohan M. Khambalkar. Review on Satellite Communication Systems.
