Abstract

Future exploration strategies plan to land both human and robotics landers in scientifically interesting zones, located prior to the mission, which often consist in inherently hazardous craterized and erosion-modeled landscapes. Because of interplanetary and reentry navigation errors, the position of the lander is not known precisely enough to guarantee a landing close to a scientific site. Thus, a geo-localized absolute navigation is added to enable the lander to assess its position with regards to these sites in real time during descent. Meanwhile, a hazard avoidance function determines the best landing site by taking into account various criteria: risks, slope, scientific interest, propellant needed, guidance constraints, Sun and Earth visibility etc. This paper will focus on geo-localized absolute navigation principles and on the development of a dynamic and adaptable multicriteria decision algorithm with a non-exhaustive search methodology to cope with stringent computational requirements.
