摘要
陀螺仪是惯性导航系统的核心器件，陀螺漂移（包括常值漂移和随机漂移）影响着陀螺仪的工作精度。简要介绍了PC／104总线，在此基础上设计了陀螺漂移性能预测系统，分析了各个模块的作用。该系统具有快速准确的预测陀螺漂移性能，对提高整个导航系统的精度有着十分重要的意义。
Gyro is a core device in the inertial navigation system, and its drifts including constant drift and random drift, effect the operational accuracy of gyro. PC/104 Bus is briefly introduced in this paper. Based on the bus, the performance forecasting system of gyro＇s drift is designed and each module of the system are analysed. This system has the function of forecasting gyro＇s drift fast and exactly, and has great value for the accuracy improvement of whole navigation system.
