Autonomous mission planning in space: mission benefits and real-time performances

International audienceIn the framework of the AGATA program we developped a ground tool to demonstrate thefeasibility and interest of autonomy for space systems. We used this demonstrator to study the impact of on-boardautonomy on both mission performances and real-time performances. We compared the results with respect tomission goals on different criteria for five levels of on-board autonomy. Our experimentation shows that missionbenefits increase with on-board autonomy level. In parallel we performed a real-time evaluation of the AGATAflight software for the higher level of autonomy. We were able to demonstrate that the central processing unit loadassociated to fully autonomous on-board mission planning is compatible with the actual Leon2 baseline
