Design of agile satellite constellation is crucial in various Earth observation missions. The access-constrained coverage analysis to evaluate optimization objective is a critical problem of agile satellite constellation design, which needs taking attitude maneuver into consideration. This paper proposes a novel multi-objective optimization framework based on task simulation, and simulates the procedures of task arranging and attitude maneuvering of an agile satellite constellation for multi-target observation. Firstly, the sensor pointing capability and observation constraints of agile satellites are analyzed. The multi-objective optimization problem model is constructed with the fitness evaluation according to the constrained coverage and observation sequence calculated by the task simulation method, and solved with multi-objective optimization algorithm for better performance. Finally, the results of simulation verify the rationality of the model and validity of the proposed method.
