Satellite Communication Systems
2004Satellite-based communication has become a major facet of the telecommunication industry for two major reasons. First, it provides a means of broadcasting information to a large number of people simultaneously. Thus, satellite communication systems are an important ingredient in the implementation of a global communication infrastructure.

Proceedings of the IEEE, 1978
This paper describes the measurement techniques employed to test the elements of a communications satellite system. Techniques for measuring the gain-to-noise-temperature ratio (G/T) of an earth station antenna are presented. The measurement of earth station polarization characteristics is discussed extensively in terms of the new requirement for ...

Satellite System Fundamentals [PDF]
, 2003 In the global communication infrastructure, satellite communication networks are important parts of any wide-area telecommunication system. Satellites have a unique capability for providing communication services over large geographical areas. Since 1965, when the first commercial satellite for international communication, Early Bird, was successfully ...
