ETS-VI multibeam satellite communications systems☆

Abstract Satellite systems are expected to play an important role in constructing economical and highly reliable communications networks in combination with terrestrial networks, and to provide attractive new communications services promptly and widely. Multibeam satellite communications technology is one of the most important technologies for improving system economy and transmission capacity for satellite communications. The multibeam satellite communications experiments are planned to be conducted using Engineering Test Satellite-VI (ETS-VI) to be launched in 1993. This paper describes the ETS-VI multibeam satellite communications systems.
