摘　　要：卫星执行飞行任务时,对卫星的定向都有预定的要求。星上控制系统与地面测控系统都需要姿态确定的信息,因此如何利用卫星遥测数据来确定卫星姿态非常必要。通过引入一个离散控制过程的系统,推导出应用于自旋卫星姿态确定的卡尔曼滤波过程。根据量测量的获取情况,首先对量测量全部正常获取时的卡尔曼滤波定姿计算方法和步骤进行详细论述,然后对其他情况下的滤波进行描述,最后给出应用情况分析。For the in-orbit satellite,the attitude determination information is very important and useful,not only to the on-board control system,but also to the groud TT&C system.Thus it is necessary and critical to determine the satellite attitude with its telemetry data.In this paper,a discrete control system is applied to derive the Kalman filter system on the attitude determination of spin stabilization satellite.According to the detected measurement,we describe the method and process of Kalman filter technology on the attitude determination,in the instance that all the detected measurement parameters are achieved correctly,and then in other instances. Finally we provide some application examples.
