摘　　要：针对航天器轨道确定后对多组轨道进行评价排序的轨道优选问题,引入了逼近理想点法设计评价指标体系,通过统计分析结合测控相关经验设计了权值,用加权平均法解决了目标轨道的求解难题,建立了轨道优选的评价模型。利用两个典型实例计算验证了算法的合理性和精确性。For optimal selection of spacecraft initial orbit detelmination, an evaluation index system derived from TOPSIS method is introduced. The weights of indices are designed on the base of the statistics analysis and ex- perts＇ experience. Then the weighted averaging method is applied to solve the object orbit calculation problem. Finally, the validity and effectiveness of the model and algorithm is verified by two typical examples.
