Abstract

Abstract: Tianwen 1 successfully achieved China’s first soft landing on the surface of Mars. The entry capsule GNC system is responsible for the attitude and orbit control during the EDL process of the entry capsule to ensure a safe landing on the surface of Mars. The flight phase division, system composition, scheme design and specific design for the EDL process of Tianwen 1 entry capsule GNC system are outlined in this paper. The actual flight results of the entry capsule GNC system during the EDL process are also provided.

Key words: Mars landing, guidance, navigation and control (GNC), Tianwen 1 Mars spacecraft, entry, descent and landing (EDL)

CLC Number:

V448.2
