Popis: The main factors affecting the temperature drift of the fiber optic gyroscope was analyzed in this paper. The autoregressive model of temperature drift related to the temperature and the rate of temperature change was built. The coefficients of the model can be obtained by least squares fitting. Experiments show that the model was effective. With the drift model the drift trend caused by temperature can be estimated. The temperature drift can be compensated using the drift trend. The experiment result shows that the drift error can be decreased about 87% after compensation.
