摘要
分析了激光陀螺仪和加速度计的误差补偿模型以及激光捷联惯性测量组合的误差补偿方法,基于四位置转位法实现了激光捷联惯性测量组合在双轴位置转台上的误差参数标定,标定结果表明,该方法能够保证激光捷联惯性测量组合的误差参数标定精度,并且具有对标定设备要求低、转动位置少、操作简单等优点,具有一定的工程应用价值。
The error compensation model of laser gyroscopes and accelerometers and the error compensation method of laser strapdown inertial measurement unit were analysized. The calibration of error parameters of laser strapdown inertial measurement unit was achieved on two-axis position turntable based on four position turning method. The calibration results show that this method can meet the calibration accuracy of error parameter of laser strapdown IMU, and it has the merit of low requirement of calibration equipment, few turning position, operation easy, etc. So it has a certain engineering application value.
