Abstract: To assign tasks of high resolution Earth Observation Satellite system (EOSs) to satellites and ground station resources while satisfying tasks logical,temporal and resource constraints,a general mission planning framework was designed.The detachable resource template,hierarchy mission template and general decision engine were the core of this framework,and the detachable resource template was defined for multi-types resource.Each functional configuration of EOSs was mapped by instantiation,and the general description of EOSs was constructed by resource component.Aiming at the complex mission modes,hierarchical mission template was presented as a process of decomposing complex mission into an activity graph with causality constraints.General solution engine for general representation of resource and task was designed,and complicated decision was decomposed into mix-initiative cooperative decision so as to satisfy maximum customers requirements.A general mission planning platform for EOSs was introduced.Application examples were used to explain problem representation and solution process in the framework.

Key words: earth observation satellite system, mission planning, detachable resource template, mission template, causality constraint
