Abstract
The error model of Shupe effect is analysed theoretically,the radial temperature levels of fiber coil will produce the zero bias drift of FOG.The experiment to measure the effect of the ambient temperature on the temperature of the fiber is designed and completed,there is a linear relationship between the change rate of ambient temperature and the error of Shupe effect.Based on the analysis,the experiment to measure the FOG output is designed under the conditions of temperature changing,the gyro output trend is modelled using the first-order、second-order and third-order.The raw data of the gyro output are compensated,the obtained temperature model is verified to set the different temperature curve under the same conditions.The result shows that using the first-order model of temperature changing the error value caused by Shupe effect can be most accurately reflected,comparing with the second-order and third-order model,it is more simple and more stable,and has good compensation effect,and this is also consistent with the conclusions of the theoretical analysis.

期刊介绍：
The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months.
The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
