Abstract:This paper presents a review of the trends in communication satellite technology. In the near term the development of moderate size, dedicated satellites is to be expected. In the long term international coordination of orbit and spectrum allocations, introduction of higher-frequency bands, spectrum conserving techniques and the concept of large communication platforms deserve particular attention. Means to improve the cost effectiveness of satellite communications system and technology aspects are considered. Finally some German contributions to these developments are presented, mainly concerning high-power TWTs in the 12 and 20 GHz range.
