Precise landing position is required for future planetary exploration missions in order to avoid obstacles on the surface or to get close to scientifically interesting areas. Nevertheless, the current Entry, Descent and Landing (EDL) technologies are still far from this capability, as the landing point is predicted with a dispersion of several kilometres.(More)
— Future space exploration missions require a precise absolute localization of the lander during descent and at touchdown , called " pinpoint landing ". This article presents the extensions of " Landstel " , a solution initially presented at Astra 2008 [10], that exploits on-board vision to localize the lander during descent with respect to orbital imagery.(More)
In this paper, we present the vision-based absolute navigation (VIBAN) system that enables the global localiza-tion ability (also called " pinpoint landing ") of the lan-der. The system integrates the absolute visual localisation (AVL) approach Landstel with visual odometry (VO), a relative visual motion estimation approach. The combination of the two(More)
