HTN-based Model and Algorithm for Autonomous Planning of Satellite

The problem of operation planning for satellite is investigated.Task decomposition approach of hierarchical task network(HTN) is adopted.Based on the analysis of system structure for satellite,the planning domain model is built and decomposition methods of two main kinds of tasks of satellite are defined.Subsequently an algorithm for the model is developed,which is based on the forward search algorithm.An example is given to evaluate the model and corresponding algorithm and the results show that the autonomous planning problem can be solved successfully using the approach.
