Development of GNC Technology for China's Deep Space Probes
GNC(guidance,navigation and control)technology is a core and key technology for deep space exploration mission.The development and achievements of GNC technology for Chi-na's deep space probes are introduced,including the development and evolution of the key tech-nology in various missions for orbiting exploration,landing and rover exploration,and return re-entry in the China Lunar Exploration Program,such as the highly reliable and accurate trajectory control technology,the adaptive powered explicit guidance,binocular stereo vision based autono-mous environment perception,the unique skip-reentry;and the key technology and achievements of Tianwen-1 Mars probe,such as the high fault-tolerant and strong autonomous landing naviga-tion in the high dynamic conditions and the rapid attitude maneuver control dealing with large dis-ruptions.Finally,the development trend and requirements of GNC technology in the field of deep space exploration in the future are forecasted,and some suggestions about autonomous control and artificial intelligence are proposed.
