Abstract:

 The necessity and difficulty of spacecraft autonomous mission plan repair are elaborated for the urgent demand for spacecraft autonomy. The definitions of spacecraft autonomous mission plan repair, plan stability and plan repair problem are given. The current methods are divided into five categories according to the repair strategy adopted in the plan execution failure, including rule matching, local adjustment, deletion/refinement, state transition, and new construction problem. The research progress and features are described in detail. The quantitative evaluation methods of plan stability are summarized. Finally, the research trend of spacecraft autonomous mission plan repair is suggested based on the analysis of the existing methods.

Key words:  Spacecraft autonomy, Mission plan, Plan repair, Plan stability
