| 摘 要： | 地磁场矢量是卫星的位置函数,利用三轴磁强计的测量信息即可实现近地卫星的自主导航.采用地磁场强度矢量为观测量,当测量值存在野值时,滤波会出现偏差,收敛变慢甚至发散.采用基于残差正交性质的EKF容错滤波方法,实现了野值的即时修正和故障检测,使滤波器具有较强的鲁棒性.仿真结果表明该方法有效.

| Abstract: | Magnetic field vector is a function of the satellite's position.Autonomous navigation of LEO satellite can be achieved based on the measurement data of the onboard three axis magnetometer(TAM).For the orbit estimation algorithm based on the measurement of the geomagnetic field vector,when measurement data influenced by outliers,filtering occurs deviation,convergence becomes slow and even diffuses.Based on residual orthogonal EKF(Extended Kalman Filter)Fault tolerant filtering method,the instant modifying and fault diagnosis are implemented and the filter obtains stronger robustness.Simulation results show the effectivity of the method. |
