| Abstract: | The guidance, navigation and control (GNC) of entry, descent and landing (EDL) plays a decisive role in the successful landing on Mars. The technical requirements of Mars EDL and challenges of GNC are firstly introduced in this paper. Then, the EDL guidance, navigation, and control schemes of previous successful Mars missions in history are reviewed and summarized in detail. Next, some useful hereditaments from current Chinese space projects are summarized. Finally, some preliminary suggestions and proposals on the EDL GNC are given for future Chinese Mars exploration missions based on the comparative analysis of the existing technologies. |
