Abstract
This paper presents the challenge of the autonomous onboard management of the mission of an Earth watching satellite within a constellation of identical satellites, then the anytime planning approach that we developed to deal with it. After a presentation of the reference mission we started from, we describe the operational constraints on the management of this mission, the resulting architectural choices we made, the need for an anytime planning module on-board each satellite, and the dynamic programming approach we chose. Then, we present the results of the simulations that have been carried out on an a priori difficult scenario to assess algorithm parameter settings and tradeoffs between computing power and decision quality. We conclude with the work that remains to be done to design a satisfying management system for each satellite and for the whole constellation.
