摘　　要：针对卫星入轨段，如何从多组初始轨道中选择一组最优轨道问题进行理论分析，提出一种基于模糊综合评价法的卫星初始轨道选优算法。首先对确定卫星初始轨道的数据源及定轨原理进行了分析；其次针对初始轨道的特点，应用模糊综合评价法建立了初始轨道选优的评价指标体系，成功利用被评对象作为评价专家，解决了评估矩阵的生成问题；最后以一颗典型的太阳同步轨道卫星为例，验证了其数学模型和选优算法的合理性和正确性。This paper presents a theoretical analysis on optimal selection of satellite initial orbits in the orbit injection phase and proposes a method to select the optimal group of initial orbits based on a fuzzy integration evaluation method. First, data source that confirms satellite primal orbit and orbit determination theory are analyzed. Second, based on the characteristics of primal orbit, the fuzzy integration evaluation method is used to establish an evaluation index system of primal orbit selection. Using successfully objects evaluated as an evaluation expert, problems in evaluation matrix building are solved. Finally, taking a sun-synchronous satellite as an example, the paper illustrates the application of the mathematical model. The model and the optimal selection method have been proved valid and effective.
