Guidance for Autonomous Precision Landing on Atmosphereless Bodies

摘要: Two key technologies that will likely fly on next-generation planetary landers are hazard detection and avoidance (HDA) vision-based navigation. The purpose of HDA is to make previously unsafe landing sites accessible by future vehicles, increase the safe probability overall. Vision-based navigation enable target specific more precisely also plays an important role for HDA. This paper formulates requirements guidance system derive from needs these new systems. After introduction a reference mission scenario with inthe-loop, extensive literature survey state-of-the-art in approach-phase guidancealgorithms presented. presents methods under angle HDA-compatibility. sheer number papers mentioned here leads conclusion trade-offs challenging. It recommended do down-selection presented here, performance-based trade study particular test case consideration few candidates. As example, E-Guidance Mercuryand Moon-landing scenario. Because results differ dramatically, it concluded essential perform actual study, trades cannot merely be based references literature. proposed method not satisfyingly robust, goal research improve upon this.
