摘　　要：工作环境温度的变化使光纤捷联惯导系统内部惯性器件产生了温度漂移,严重影响了系统输出精度。该文从便于工程实现角度出发,设计了一种基于光纤陀螺和石英加速度计温度漂移建模与补偿的方法。建模过程中参数取值通过转台试验获得。验证试验结果说明了建模与补偿的正确性与实用性。The changes of environmental temperature caused temperature drift of the inertial components in FOG inertial navigation system which had serious impact on the precision system output precision. From the aim of engi- neering realization, this paper designed a modeling compensation method based on the FOG and quartz accelerome- ter. The parameter were gotten form the test of turntable. The results of test showed that the modeling and com- pensation was correct and practical.
