摘　　要：陀螺组合的安装误差会引起陀螺漂移,从而对惯导系统产生影响。从挠性陀螺组合安装误差模型入手,推导出存在轴不对准角情况下的挠性陀螺组合静态误差标定模型,并给出静态误差标定的位置试验方案。提出的标定方案可以有效标定陀螺组合静态误差系数,从而减少陀螺漂移。Installation error of gyroscope integrated can lead to gyro drift. Thus, the precision of INS is influenced. The installation error model of the gyroscope integrated is analyzed, and then error calibration model of flexible gyroscope integrated is deduced when malalignment angle is considered. Position test scheme of static error calibration is also presented. The scheme can calibrate static error coefficients of gyroscope integrated. Thus, the gyro drift is reduced.
