摘要
在分析星座轨道要素的基础上,研究了用改进非劣分层遗传算法(NSGA-Ⅱ)对中轨道(MEO)卫星的区域通信卫星近地点幅角、升交点赤经和平近点角等星座参数进行优化的方法,并对有5颗椭圆中轨卫星的星座进行了优化仿真。结果表明,优化后的星座不仅能在我国领土范围内提供实时通信服务,而且具有一定的全球覆盖能力。
Based on the analysis of major parameters of orbit, the optimal method for constellation parameters of MEO communication regional satellite such as perigee argument, longitude of ascending node and mean anomaly by nondominated sorting genetic algorithm （NAGA-Ⅱ ） was put forward in this paper. The optimal simulation of a 5 satellites constellation was made. The result showed that the optimized constellation could provide communication in time for China and had the certain capability of global coverage.
