Research Status and Developing Trend of the Autonomous Navigation, Guidance, and Control for Planetary Landing

Abstract

Autonomous navigation,guidance,and control is one of the key technologies for planetary landing,which has a direct impact on mission success. In this paper,the necessity and importance of the further research on the autonomous navigation,guidance,and control are elaborated focusing on the developing demand for the Mars and small body landing mission in the future. Based on the environment features,the challenges encountered for the autonomous navigation,guidance,and control are analyzed. Then and the key techniques involved are discussed,and the state-of-the-art techniques and research tendency of the autonomous navigation for planetary landing are summarized. Finally,the development trends of the autonomous navigation,guidance,and control for Chinese planetary landing mission in the future are previewed.
