GNC DESIGN AND VALIDATION FOR PRECISION LANDING AT THE MOON AND MARS

摘要

Precision landing is a critical and challenging requirement for future planetary exploration landing missions. In order to meet these requirements, a GNC architecture is proposed for autonomous planetary landing applications. The GNC design proves to meet a 200 m landing accuracy at the Moon and a 10 km landing accuracy at Mars, relying on vision-based navigation technologies (for Moon), guided entry (for Mars) and innovative navigation concepts. Performance of the GNC is validated through Monte-Carlo simulations campaigns, in closed-loop in a high-fidelity simulation environment.
