Spatial thruster is the important component for orbit maintenance, station keeping as well as special attitude control of the microsatellite. With the development of micro/nano satellites and their constellation and formation flying, more advanced spatial propulsion technology is required. In this paper, the review of MEMS-based micropropulsion developments is summarized. Based on it, the overall structure scheme of MEMS micro-thruster arrays is presented. Then the simulation and analysis of mechanical prop...
