Abstract: |
With the development of space technology under the new decade, geostationary satellites with 15-year lifetime and low-orbit satellites with over 8-year lifetime require high performance propulsion system. In this paper, based on analysis of foreign advanced chemical propulsion technology, electric propulsion technology, micro-propulsion technology and new concept propulsion technology, the developing status of foreign satellite propulsion technology is illustrated;the developing direction of satellite propulsion technology in the next 20 years is included;and the enlightenment on the future development of China’s propulsion technology is presented. |
