摘　　要：为提高无陀螺捷联惯性导航系统(GFSINS)九加速度计配置的角速度解算精度,文中提出使用扩展卡尔曼滤波算法,该方法更精确地估算出角速度的误差,并对角速度进行线性补偿。通过仿真分析表明,该方法可以有效地提高角速度解算精度。For improving the accuracy of the angular velocity calculation in the nine accelerometers configuration of GFSINS, the extended Kalman filer algorithm is presented in the paper, which makes the error estimation more accurately and gives the angular velocity a linear compensation. The simulations have shown that the method could improve the calculative accuracy of the angular velocity effectively.
