Abstract: In recent years, benefited from the rapid development of platform technologies such as electric propulsion, power supply and thermal control, the major manufactures of foreign GEO communication satellites have successively completed the research, development and finalization of the new generation of GEO all electric propulsion satellite platforms. These new generation platforms have significant reference significance for the development of China GEO satellite platforms in terms of design concepts, application of new technologies and low costs. Combing the technologies and characteristics of the new generation common platform of various types of GEO communication satellites abroad like Spacebus NEO, Eurostar NEO, Space Inspire, OneSat and etc., the market trends, development and design ideas of new generation GEO communication satellite platforms are analyzed. At the same time, the design requirements and technical directions of the platform related electric thrusters, power processing units, thrust vector adjustment mechanisms and thermal control are analyzed. Development suggestions for the common platform of China next generation GEO communication satellites are proposed, which can serve as a reference for the development of China future GEO satellite platforms.

Key words: GEO communication satellites, common platform, all electric propulsion
