Symmetry-based Walker constellation network topology planning calculation optimization method

According to the symmetry-based Walker constellation network topology planning calculation optimization method provided by the invention, the Walker constellation symmetry is utilized, so that the calculation consumption and the storage resource consumption in the topology planning process can be greatly reduced. Specifically, a satellite in a constellation is selected, orbit extrapolation and visibility calculation are carried out on the satellite and satellites having a link establishment plan with the satellite, and a visible time period is obtained; then, obtaining visible time periods between other satellites in the network and satellite nodes with link establishment plans of the other satellites by using the symmetry of constellations; and obtaining a satellite network topology planning scheme by executing a longest link duration algorithm according to the obtained visible time periods among the satellites in the constellation. 本发明提出了一种基于对称性的Walker星座网络拓扑规划计算优化方法，通过对Walker星座对称性的利用，可大幅降低拓扑规划过程的计算消耗以及存储资源消
