摘要
为降低光纤捷联惯导系统标定对转台的要求,缩短标定时间,提出了一种利用双轴转台完成的八位置标定方法。根据光纤陀螺和石英加速度计的简化输出模型,在双轴转台上合理选择编排八个标定位置,利用输出脉冲量对光纤惯组的27个参数进行解算。通过数学仿真,该方法与使用传统方法标定精度相当,但标定时间短,方法简单易行。
To reduce the requirement for turntable in calibration of fiber optic gyroscope （FOG） strapdown inertial measurement system （SINS） and shorten test time, an eight-position calibration meth- od using two-axis turntable is presented. According to simplified model of FOG and quartz accelerometer, eight-position used in calibration are reasonably arranged and scheduled on two-axis turntable. By taking pulse counts, the overall 27 parameters of SINS are identified. The mathematic simulation verifies that the accuracy of this method is equivalent to that of the classical calibration on precision turntable but easier than the latter.
