中文摘要：
为了简化标定设备,降低标定成本,该文研究了利用双轴位置转台进行光纤陀螺惯组标定的可行性,分析了转台位置误差对光纤陀螺惯组标定结果的影响。分别建立加速度计和陀螺的标定模型,推导出利用双轴位置转台进行标定的相关算法及设计了新的标定方案,且进行了相关实验,对实验数据分析结果表明,利用双轴位置转台进行光纤陀螺惯组的标定,标定值与真值基本一致,方案可行。此外,经实验分析,转台测角误差所引起的标定误差最大为2.42×10^-6,数值较小,在实际应用中可忽略。
英文摘要：
To simplify the calibration equipment and lower the cost, the feasibility of calibratiing FOG strapdown inertial navigation system（SINS） through the two-axis position turntable has studied in this paper. And the effect of the turntable position error on the calibrating results of FOG inertial measurement unit（IMU） has been analyzed. Secondly, the FOG unit error model and accelerometer unit error model have been established, and the relevant a- rithmetic of calibration has been derived. A new method of calibration is performed and experiments are carried out. The results of experiments show that the precision of calibration is consistent with the true-value and the proposed method is feasible. Moreover, the maximal calibration error brought by the turntable measurement is 2.42 × 10^-6 , which is so little that can be ignored in practical application.
