光纤陀螺仪测试研究

study on the test of Fibre Optic Gyroscope Chen Jiabtin Miao Lingjuan Liu Xingqiao

论述了光纤陀螺仪测试系统的组成。对光纤陀螺仪的偏值稳定性、输入轴失准角和随机游走系数等进行了测试和分析，对陀螺仪随机漂移模型进行了辨识，分析了转台误差对陀螺仪输入轴失准角测试精度的影响．所得结论为陀螺仪生产工艺的改进。

A fibre optic gyroscope test system is presented. The bias stability, input-axis disalignment angle and the random walk coefficient are tested The gyro random driftmodel is identified,and the influence of the tumtable errors on the test accuracy of gyro input-axis disalignment angle is analyed. The results can be used to improve the technology of fibre optic gyroscope producing , and are also useful for modeling and compeusating the fibre optic gyroscope errors.
