Abstract

Compared to traditional non-agile imaging satellites, the imaging efficiency of agile satellites are far higher and the imaging requirements are correspondingly more sophisticated, which in turn calls for better design and implementation of the onboard autonomous mission management system. According to the characteristics of the autonomous mission management system of agile satellites, this paper presents and illustrates the functional modules and key technology required by the autonomous mission management system. This paper proposes a layered architecture design, which employs a progressive and gradually detailing way to facilitate the systematic modular design and to effectively reduce the complexity of the implementation of the design. Combined with mission plan, emergency replan, image parameter real-time calculation technique, autonomous monitoring technique of plan implementation and other techniques, this design makes the agile imaging mission more scientifically designed, properly scheduling and safely implemented.
