【摘要】 对光学陀螺捷联惯性组合的系统级标定方法进行了研究。在对惯性测量元件误差模型进行分析的基础上,对标定参数的选择、参数的解算过程以及精度分析等方面进行了研究。设计了一种基于转动支架多位置转动的系统级标定方法。仿真结果表明,该方法能够满足系统精度指标要求。更多还原

【Abstract】 In this paper,a new systematic calibration method for laser gyro strapdown inertial measurement unit(SIMU) is proposed,including the calculation course of error separation and the analysis of the error models of gyro and accelerometer etc.By comparing with the classical methods,this method alleviates the dependence upon high precision test facilities.The simulation results are analyzed and show that this method fulfills the requirements of system precision index.更多还原
