通过设计一种实用的激光陀螺捷联惯性导航系统自标定算法,保证在外场使用情况下,能对惯性器件误差(三个陀螺漂移和三个加速度计零位)进行精确标定,确保系统长期使用精度。在完成算法设计的基础上,进行了仿真计算,取得满意的仿真结果。
The aim of this paper is to assure the ring laser gyro strapdown inertial navigation system's high accuracy in the long run by means of designing a kind of practical self calibration method to calibrate accurately three gyro drift and three accelerometer biase under actual condition. On the basis of accomplishing the algorithm design we have finished the simulation and the simulation results are satisfactory.
