摘　　要：平台漂移误差标定是保证惯导系统精度的基本措施之一。针对陀螺稳定平台漂移系数标定问题,提出一种新的动态标定方法,可标定陀螺仪的9个误差系数。不借助于外部精密转台,利用陀螺平台自身系统,控制平台台体绕某轴连续转动,分离其他两轴所对应陀螺的漂移系数。从机理上分析陀螺平台漂移动态标定误差模型建立及标定方法,对标定误差做了详细分析,提出减小或消除系统误差的措施,为提高标定精度提供了依据。Drift error calibration of inertial platform is one of the most important processes to ensure the accuracy of INS. A new method of dynamic calibration for gyro-platform drift is presented, and then 9 parameters can be obtained. Using the self-system of the platform and controlling the platform to rotate around an axis, the drifts of gyroscopes for other two axis are separated. The method of dynamic calibration is analyzed in theory, and the way of reducing errors is proposed based on detail analysis on calibration error, which will contribute to improving the calibrating precision.
