摘　　要：为缩短区域覆盖星座优化设计的计算时间,对网格点仿真法进行了改进。在统计时间内,以解析法计算卫星覆盖时刻集,并采用遗传算法优化星座参数。仿真计算结果表明,本文改进方法的计算时间仅为优化前的百分之一。To shorten the computation time of optimal regional coverage constellation, an improved method of grid simulation was put forward in this paper. Analytic method was used to calculate the coverage performance during the statistical period, and the genetic algorithm was applied for optimal design of satellite constellation. The simulation result showed that the processing time of new method was one hundredth of the old one.
