摘　　要：针对航天器入轨段,如何从多组初始轨道中选择一组最优轨道问题,进行了深入地理论分析,提出了一种基于灰色关联分析法的航天器初始轨道选优算法。根据航天器初始轨道的设计特点,创新地利用标称轨道作为属性基向量,解决了比较数列的生成问题,建立了灰色关联分析法的初始轨道选优决策数学模型以及求解的七个基本步骤,最后以一颗太阳同步轨道卫星为仿真算例,验证了数学模型和选优算法的合理性和正确性。Theoretical analysis was proposed in the optimal selection of spacecraft initial orbits during the orbit injection phase, and an algorithm based on grey relational analysis was proposed to select the optimal initial orbit. Considering the design features of the spacecraft initial orbit, the nominal orbit was used as attribute base vector to solve the problem of comparison sequence generation. A decision mathematical model based on the grey relational analysis was generated to solve the selection problem of optimal initial orbits, and details were given to the seven basic solution steps. Eventually taking a sun-synchronous satellite as a simulation example to illustrate the application of the mathematical model, the model and the optimal selection algorithm have proved valid and effective in practice.
