摘　　要：分析了卫星遥测数据的变化规律,提出了一种基于卡尔曼(Kalman)滤波的遥测数据判读系统框架,并定义了系统中各模块的功能及接口关系,应用卫星实际遥测数据对判读系统的数据预测效果进行了验证。结果表明,此系统对数据异常反应迅速,能够很好地满足卫星测试的实时性要求。By analysing the telemetry data according to their transforming rules, the paper propo- ses an interpretation system based on Kalman filter for satellite. Besides, the functions of every module and the interfaces are defined. Finally, by taking advantage of the telemetry data, the sys- tem proposed is verified. The results show that this interpretation system has good performances in detecting data abnormal and can meet real-time requirements of the tests for satellite.
