导航卫星健康管理协同仿真验证系统设计与实现

Design and Implementation of Collaborative Simulation Verification System for Navigation Satellite Health Management

针对导航卫星缺乏健康管理辅助设计和验证手段,健康管理指标参数不系统、不量化等问题,提出了面向导航卫星在轨信号服务性能和安全稳定运行保障需求的健康管理建模方法和指标计算确定方法,搭建了卫星健康管理协同设计与仿真验证系统。一方面可以协助卫星设计人员开展健康管理方案设计,构建系统的、定量的健康管理指标体系;另一方面可以通过数据驱动,验证卫星健康管理系统设计的正确性和合理性,对相关的故障诊断、预测和恢复算法进行评估,为卫星健康管理系统设计、开发、评估与配置等工作提供有力支撑。

To solve the problems of lack of auxiliary design and verification means of navigation satellite health management,and the unsystematic and non-quantification of health management index parameters,the health management modeling method and index calculation and determination method based on-orbit signal service performance and guarantee requirements of safe and stable operation of navigation satellite are proposed,and the health management collaborative design and simulation verification system is established.On the one hand,this system can assist satellite designers to carry out health management scheme design and build a systemic and quantitative health management index system.On the other hand,it can verify the correctness and rationality of satellite health management system by data driving,evaluate relevant fault diagnosis,prediction and recovery algorithms.It can provide strong support for the satellite health management design,development,evaluation and configuration.
