静电陀螺监控器中陀螺漂移模型系数的标定方法研究

Calibration of Drift Coefficients of ESG ESGM

利用改变舰艇标定中所处纬度的方法实现对静电陀螺监控器(ESGM)极陀螺漂移模型系数的分离,从而为进一步精确地标定ESGM奠定基础。采用了卡尔曼滤波算法,并考虑了工程应用的可行性。仿真分析表明,所提出的标定方法是可行的,并能有效提高ESGM的导航精度。

By uncoupling the error coefficients of the pole gyro through changing the latitude, the two coefficients can be calibrated respectively. Kalman filtering algorithm is adopted based on the feasibility of engineering application. The simulation study shows that this method is effective.
