| 摘 要： | 以3颗微小卫星在同一个轨道面内编队飞行,并对地进行三维立体测绘为背景,给出了基于改进型遗传算法的空间圆形编队队形优化设计的方法,该方法可以保证编队队形在各种摄动力下长期稳定.结合编队飞行星间链路的特殊要求,推导了低轨道编队卫星星间链路的计算公式,确定了星上发射机功率.搭建了星间直序扩频通信系统模型,并对其进行了仿真.建模及仿真结果为后续研究编队飞行和星间通信演示试验提供良好的理论基础.

| Abstract: | The method of space circular formation order optimized design was given by using the reformed heredity algorithm based on three micro-satellites flying in formation on a same orbit and by performing the three dimensional solid mapping for terra.The method could ensure steady formation order for a long time under various perturbations.The calculated formula of the inter-satellite links of LEO formation-flying satellite was derived according to the special requirements of inter-satellite links of the formatio... |
