An HTN-based mission planning model and algorithm for autonomous spacecraft

The problem of mission planning for autonomous spacecraft is investigated. Based on hierarchical task networks planning approach, the mission planning model of autonomous satellite is built and decomposition methods of two main kinds of tasks of satellite are defined. Subsequently a heuristic algorithm for the model is developed based on the forward search algorithm. At last, an example is given to evaluate the model and corresponding algorithm, and the results show that the mission planning problem of autonomous spacecraft can be solved successfully using our approach
