Study of Ultra Precision and Micro-Newton Level Microwave Ion Propulsion Technology and Application in Satellite Ultra-Precision Control

The rapid development of space technology makes it possible to build large space constellations using the formation of space satellites, and it plays an important role in the task of gravitational wave detection, radio telescope formation and constellation network. Ultra-precision control is the key technology to achieve the high precision formation of the satellite. The propulsion system is an important component of the high stability of the long-term flight of the satellite formation and the correct operation of the internal scientific device. Different from the conventional propulsion system, the precision formation of the satellite precision formation is highly required for the propulsion system to adjust the range, resolution, response time and thrust consistency. Based on the requirements of the aircraft''s precision formation task, this paper analyzes the function and technical requirements of the micro-ball-type propulsion system, and puts forward the system of the satellite ultra-precision control propulsion system based on the M2 microwave ion thruster. This paper briefly introduces the key technology and research progress of M2 ultra-precision micro-beef advanced propulsion system, and lays the technical foundation for follow-up research.
