Abstract: In order to ensure the stability of the navigation signal in wartime area, satellites are required to enhance the power of ground area. Planning for large-scale power enhancement missions can ensure the enhancement effect. In this paper, for the problem of navigation satellite power enhancement task planning, the problems of star-ground visibility and time window conflict of adjacent tasks are analyzed. A power enhancement task planning model is constructed, and an adaptive ant colony algorthim based on ant colony system and maximum and minimum ant system is selected. The task revenue parameters are introduced to improve the optimization strategy of the algorithm, and to speed up the convergence rate of the algorithm as well as to avoid falling into the local optimal solution. Experimental results show that the improved ant colony algorithm designed in this paper has a good planning effect for large-scale power enhancement tasks.
