摘　　要：卡尔曼滤波是提高陀螺精度的重要手段。陀螺原始信号中常常含有大量随机误差,这使得陀螺的精度大大降低。研究了适用于陀螺精度的滤波方法,探讨了基于卡尔曼滤波的方法在提高陀螺精度上的应用,并通过分析验证了所研究的算法的有效性和适用性。Kalman filtering is an important means to improve the accuracy of gyro.Gyro original signal often contains a lot of the random error,which makes the gyroscope accuracy greatly reduced.This paper studied the filtering method for the accurate gyro,discussed the application of Kalman filtering in precision gyroscope,and verified the validity and applicability of the algorithm by an example.
