Operation Planning Modeling of Tracking and Data Relay Satellite: A Sketch

Planning of Tracking and data relay satellite is a important problem which focuses much attention recently. Based on the analysis of operation planning for tracking and data relay satellite (TDRS), a new approach of modeling of operation planning based on state and action models is proposed, which has powerful representation capabilities compared with traditional planning approach. The domain knowledge of TDRS is represented by using planning domain definition language(PDDL) ,which can represent duration constraints, resource constraints and exogenous events constraint. The domain model of operation planning for TDRS is constructed. By analyzing working mode of TDRS we can obtain useful domain knowledge which can be introduced to carry out decomposition of the operation plan into smaller sub-plans and give the corresponding selectable action set of each sub-plan, which can reduce the search space and improve the solving efficiency of operation planning problem.
