摘要
光纤陀螺具有精度高、随机游走系数小等特点,但其对热环境较为敏感,因此系统设计时需重点考虑减小环境温度对光纤陀螺精度的影响。为了减小温度对系统精度的影响,在系统级采用基于恒温与变温相结合的综合温度补偿技术,主要包括IMU和旋转机构之间的安装误差的温度补偿、陀螺标度因数误差的温度补偿以及陀螺漂移的温度补偿。该温度补偿方法具有很高的工程应用价值。
FOG is one kind of gyro with high precision and little random walk. But it is sensitive with the temperature of environment. We should focus on how to weaken the influence of environment temperature. So we design a compensation method of temperature error based on a combination with constant temperature and change temperature. This method includes compensation method of fixing error between IMU and rotation machine, scale factor error of FOG and the drift error of FOG. This method can achieve a high precision and satisfy the application of engineering.
