基于灰色关联分析的卫星初始轨道优选方法

Selection of the Optimal Satellite Initial Orbit Based on Grey Relational Analysis

卫星初始轨道优选是一项复杂而且具有多目标性的问题,所以必须利用一系列的评价指标才能全面系统地评价各种初始轨道.针对各种数据源确定的多组初始轨道如何选优问题,提出了一种应用于卫星初始轨道优选的灰色关联分析方法,建立了初始轨道选优的评价指标体系,成功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并给出了具体的应用实例.实例计算结果表明,该方法计算简单,结果可靠,可为决策者的选择提供依据.

The selection of the optimal satellite initial orbit is complex ,therefore a series of evaluation index are necessary for evaluating various initial orbits comprehensively .For Aerospace Control Center , to choose the optimal orbits from the sets of initial orbit determined by various data sources ,a method for selecting the optimal satellite initial orbit based on the Gray Relational Analysis （GRA） is proposed , and the evaluation index system for the initial orbit selection is established . T he problem of the generation of comparative sequence is solved successfully by using the nominal orbit as attribute-based vectors .The calculation results obtained from its application show that the method is simple and reliable , w hich can assist the decision-makers in the selection .
