To assess the performance of the proposed approach, a simulation environment is developed, taking as a scenario the navigation to a triangular lagrangian point of Didymos system, and having as a target 10m rms position accuracy. Alternative formulations of the position fixing are evaluated and compared. Results show the effectiveness of the proposed approach to meet the target position determination accuracy.

Abstract

We consider the autonomous optical navigation problem for a CubeSat mission to a binary asteroid system. We aimed at providing an approach which limits the computational burden, as to be suitable for real time on-board implementation. To this end, we formulate a theoretical framework which makes use of analytical results for the position determination from imaged ellipsoid targets. To assess the performance of the proposed approach, a simulation environment is developed, taking as a scenario the navigation to a triangular lagrangian point of Didymos system, and having as a target 10m rms position accuracy. Alternative formulations of the position fixing are evaluated and compared. Results show the effectiveness of the proposed approach to meet the target position determination accuracy.
