Paper Abstract

Due to long round-trip communication delay and low telemetry bit-rates, the traditional Guidance Navigation and Control (GNC) mode based on Deep Space Network (DSN) is no more suitable for landing spacecraft on small celestial bodies. This paper presents an image-based navigation and guidance scheme for future asteroid landing mission. Firstly, an autonomous navigation scheme based on feature detection and tracking technology is presented. Secondly, proportional plus derivative (PD) guidance control laws and Pulse-Width and Pulse-Frequency (PWPF) modulator are designed to track the desired descent trajectory and achieve landing on asteroids safely. Finally, the validity of the proposed scheme is confirmed by computer simulation.
