EMBEDDING PLANNING SYSTEMS IN THE FLIGHT SOFTWARE OF AN AUTONOMOUS SATELLITE

摘要

Space missions may benefit from a more advanced autonomy level in different ways: reduction of ground operations, reduction of the occurrence of service interruptions or improvement of the reactivity of the system. Depending on the mission requirements, new functions need to be supplied on-board the spacecraft, such as mission planning or failure diagnosis and automatic reconfiguration. Our work focused on the integration of planning systems and of dynamic replanning capabilities into the flight software of an autonomous satellite. Especially, we address the problem of controlling several dedicated planners which have various behaviors (anytime planning, “batch” planning, etc.) and need to be coordinated.
