Abstract
This paper presents an autonomous landing navigation and guidance scheme for future asteroid sample return mission. An autonomous navigation scheme based on feature tracking technology is brought out firstly; secondly, desired descent landing trajectories with the initial and terminal constraints are planned in order to achieve arrive-at-time landing on an asteroid; then, two guidance control laws, based on error phase analysis method and PD plus PWPF method respectively, are designed to track reference descent trajectory; finally, the validity of the proposed scheme is confirmed by computer simulation.
