摘要
对在轨卫星遥测数据的变化规律进行了分类,研究了数种主流的数据预测理论并分析了其适应性,由此提出了一种基于历史遥测数据的在轨卫星故障预警系统构架,并定义了其中各模块的功能以及接口关系,给出了实际应用的效果。这个系统对及早发现故障、维持在轨卫星的安全稳定运行具有重要价值。
The telemetry data are sorted according to their transforming rules; four kinds of mainstream data forecasting algorithms are researched and their applicability is analyzed. Grounded on this,the paper proposes a warning system based on historical telemetry data for satellites on orbit. Besides,the functions of every module and the interfaces are defined. This warning system has good performances and is of great value in early detecting the failures and maintaining satellites functioning well on orbit,which has been validated by the application results.
