Gradient based reachability analysis for goal-oriented guidance Application to Eros proximity operations
<|reference_start|>Gradient based reachability analysis for goal-oriented guidance Application to Eros proximity operations: The recent growing interest in small solar system bodies such as asteroids and comets for scientific inspection, exploitation of resources, and planetary defense reasons is pushing the development of innovative engineering solutions to better investigate these celestial bodies. Current approaches for autonomous proximity operations often relies on tracking a reference trajectory previously designed and optimized on-ground. An innovative concept developed in recent years is proposing a paradigm shift towards autonomous goal-oriented strategies, providing the probe with high-level tasks and enabling replanning capability on-board. A gradient base reachability exploration scheme is introduced in this work to efficiently compute high reward paths with limited computational resource. The methodology is tested in a case study involving proximity operations to asteroid (433) Eros, comparing the proposed approach with other exploration techniques and showing promising results.<|reference_end|>
