地外天体着陆自主避障制导技术研究进展

Focusing on the requirements of extraterrestrial soft-landing exploration, the research progress of autonomous obstacle avoidance guidance technology for extraterrestrial landing is elaborated. Firstly, the typical landing missions on extraterrestrial body are reviewed and analyzed, and the challenges and difficulties faced by landing hazard avoidance guidance are summarized, such as complex and diverse topography, limited control resource, high hazard avoidance accuracy and limited on-board computing resources. On this basis, the research status of landing hazard avoidance guidance is reviewed from two aspects:autonomous hazard assessment and autonomous hazard avoidance. Finally, combined with the requirements of future extraterrestrial body exploration missions, the development direction of landing hazard avoidance guidance technology is prospected.
