经过为期两年的科研攻关,近日,中国航天科技集团公司五院502所电推进平台控制系统一体化设计方案新鲜出炉。这标志着我国已经初步掌握电推进卫星GNC(制导、导航与控制)系统设计方法,我国在电推进卫星理论研究与工程设计工作中取得重要进展。如何在“卫星大脑”GNC系统的操控下帮助电推进航天器进行轨道转移、精确入轨以及在轨控制是世界性难题。“与传统的化学推进航天器
After two years of scientific research, recently, China Aerospace Science and Technology Corporation No. 502 of the platform for the integration of electric propulsion platform design freshly baked. This indicates that China has initially grasped the design method of the GNC (guidance, navigation and control) system for electric propulsion satellite, and China has made important progress in the research and engineering design of electric propulsion satellite. How to help the electric propulsion spacecraft to orbit under the control of the ”satellite brain“ GNC system, the precise orbit and in-orbit control are worldwide problems. ”With traditional chemical propulsion spacecraft
