摘要
给出了激光陀螺捷联惯性组合(IMU)的误差模型,研究了一种利用双轴带温控箱速率转台的参数标定方法,标定出了 IMU 在各种环境温度下的模型参数,通过温度补偿有效地减小了IMU 的导航误差。试验结果表明:该方法标定精度较高,适用于中等精度 IMU 的参数标定。
In this paper, the error model of laser strapdown inertial measurement unit (IMU) is given. A calibration method for model parameters is designed by using double axes speed turntable with temperature control box. The parameters are calibrated in various environment temperatures. The navigation error of IMU is reduced by temperature compensation. The experiment results show that this calibration method is accurate and applicable to the medium-accuracy IMU.
