行星着陆自主导航与制导控制技术是行星着陆过程的核心技术之一,关系到行星着陆任务的成败。本文基于未来火星和小天体着陆对自主导航与制导控制技术的发展需求,阐述了进一步开展自主导航与制导控制研究的必要性,围绕行星着陆过程环境特点,分析了自主导航与制导控制技术所遇到的挑战,随后概括了行星着陆自主导航与制导控制所涉及的关键技术,并综述了关键技术的研究现状。最后对我国未来行星着陆探测自主导航与制导控制技术的发展方向进行了展望。
Planet landing autonomous navigation and guidance control technology is one of the core technologies in the process of planetary landing and relates to the success or failure of the mission of the planet. Based on the future development of autonomous navigation and guidance control technology for the landing of Mars and small celestial bodies, this paper expounds the necessity of further research on autonomous navigation and guidance control. Based on the environmental characteristics of the process of planetary landing, this paper analyzes the problems encountered by autonomous navigation and guidance control technology Then the key technologies involved in autonomous navigation and guidance control of planetary landing are summarized, and the research status of key technologies are summarized. Finally, the prospect of autonomous navigation and guidance control technology for the future of planetary landing detection in China is prospected.
