摘要

摘要:
卫星系统效能评估问题，是卫星提高工作效率和卫星方案优化设计的基础。以对地观测卫星姿态控制系统作为效能评估的对象，通过对卫星的任务需求进行分析，建立对地观测卫星姿态控制系统效能评估指标体系；基于灰色关联分析相关理论，引入熵权法计算指标权重，建立效能评估模型，计算得到综合灰色关联度，实现卫星姿态控制系统效能评估；通过数据验证所建体系具有可实现性与实用性。

Abstract:
The problem of satellite system effectiveness assessment is the basis of satellite efficiency improvement and satellite program optimization design. Taking the attitude control system for earth observation satellite attitude control system as the object of effectiveness assessment, an analysis of satellite requirements is conducted to establish the effectiveness assessment index system for the earth observation satellite attitude control system. Based on the theory related to gray correlation analysis, the entropy weight method was introduced to calculate the index weights, and the effectiveness assessment model was established to calculate the comprehensive gray correlation degree, and realize the effectiveness assessment of satellite attitude control system. The realizability and practicality of the established system were verified through data.
