| 摘 要： | 针对三轴稳定卫星进行了正常飞行模式下无陀螺姿态确定算法研究，采用磁强计、地球敏感器和太阳敏感器组合获得姿态数据，利用四元数法和高斯－马尔可夫过程建立了姿态确定估计器算法模型。通过数学仿真证明，此姿态确定算法能够对星体姿态进行较精确的估计或校正，满足卫星控制精度要求。

| Abstract: | This paper deals with gyro less attitude determination algorithms using data from continuously running magnetometers, earth sensors and sun sensors for three axis stabilized satellite during normal operation. Based on EKF technique, an attitude estimator is designed which adopts the quaternion representation and Gauss Markov process. Simulation results show that precise attitude estimation or correction to satisfy with the need of control resolution of satellites can be achieved using the attitude determination algorithm derived in this paper. |
