Abstract: Owing to the limitation such as time window under the dynamic change of observed demand,ground observation scheme could not be adjusted rapidly.To solve this problem,the satellite should have autonomous planning ability,so the problem of automated planning for agile imaging satellite was researched.The working model and the architecture of automated planning based on combining planning,decision making and information feedback were presented.The architecture,components and functions of automated planning were introduced.The model was constructed according to the satellite physical constrains and operational constrains.A rolling planning heuristic algorithm was presented which used a series of local planning instead of global planning,so the satellite could plan and observe simultaneously.Satisfactory results were obtained through experiments,which showed that the model and the architecture of automated planning was reasonable and the algorithm was efficient.

Key words: agile imaging satellites, autonomous task planning, rolling planning, heuristic algorithms
