摘要: 在惯性导航系统中,传统的加速度计标定方法有些对转台依赖性比较高,对转台无依赖性的方法精度又比较低.对此,提出一种无需转台的加速度计高精度标定方法.该方法只需要采集十二个位置的静态加速度计输出数据,即可对加速度计零偏、标度因数、安装误差等系数进行高精度标定.实验结果证明,该方法与传统无转台加速度计标定方法相比,具有更高的精度.Abstract: In inertial navigation system,some traditional calibration methods of accelerator mainly rely on turntable,other methods without the support of turntable have less accuracy.Therefore,this paper presents a high-accuracy calibration method of accelerator without the support of turntable.It only needs 12 static output data of accelerator to calibrate the bias,scale factor and misalignment.Experiment results indicate that this method has higher accuracy compared with traditional calibration method without the support of turntable.
