| 在姿态控制系统中，作为传感器的陀螺所起的作用至关重要，尤其是在系统动态环境比较恶劣的情况下，需要陀螺测量的载体旋转速度准确且满足实时性要求，否则会造成大的误差，严重时会造成姿态失控。针对某型惯测组合中的光纤陀螺，分析了测量延时产生的因素，提出了一种在转台上低采样频率情况下精确测量延时量的方法。通过实际试验，得到的结果与理论分析一致，验证了该方法的正确性和测量精度。 |

| Abstract: |
| The function of gyroscope is very important in attitude control system.High accurate and real time output of rotational velocity of vector are crucial for a steady state system in harsh dynamic environment，otherwise，the systematic error would appear，or even lead to loss of control.In this paper the cause of delay characteristic for FOG was studied，and the accurate measurement method in the case of low frequency sample on test tables for delay differential was proposed.Finally，the precision and accuracy in the measuring method were verified by experiment，and the results were consistent with theoretical analysis. |
