摘要： 光纤陀螺漂移的温度模型可分为静态和动态温度模型。通过控制温控箱的温度变化率，对光纤陀螺进行温度实验，建立其漂移的静态、动态温度模型，以研究温度、温度变化率和温度梯度对光纤陀螺漂移的影响。研究结果表明，温度变化率和温度梯度对光纤陀螺漂移的影响不容忽视；考虑了温度和温度变化率（或温度梯度）的动态模型的补偿精度比单纯考虑温度的静态模型提高了50％。因此在对光纤陀螺建立温度模型时，应该建立动态温度模型，以取得较好的补偿效果。

Abstract: Temperature of FOG drift can be described either with a static model or a dynamic model. Having obtained experimental data by controlling the temperature changing rate around FOG, the two kinds of models were established to study the affects of temperature, temperature changing rate and temperature gradients of FOG drift. The results show that effects of temperature rate and its gradients are not invisible. The compensation accuracy by dynamic model considering both temperature and temperature changing rate or temperature gradients is better than static model by 50 percent. The latter only considers temperature. Therefore the dynamic temperature model should be used for better compensation.

Key words: FOG, gyro drift, temperature, temperature changing rate, temperature gradient
