摘要
在惯性导航领域,磁力计的校准需用到无磁旋转平台并进行误差建模等,这对设备及技术均有一定的要求。考虑到磁力计标定及校正的可操作性和时间成本,在利用磁力计进行初始对准时,较快、较简便的对磁力计误差进行校正是问题的关键。因此,文章提供了一种无需使用旋转平台和大量数据运算的圆盘旋转标定方法。
In order to improve the accuracy of measurement,the initial alignment problem of sensors shoule be solved in order to improve the accuracy of MEMS inertial navigation system used in all kinds of small UAV,the accuracy of MEMS inertial navigation system is not high.Magnetometer is a kind of sensor that uses the geomagnetic field to obtain the attitude angle of the carrier.It is widely used in the fields of aviation,navigation,vehicle location,geological exploration ang so on.The navigation accuracy of the carrier can be improved by combining the magnetometer with the gyroscope and accelerometer.In this paper,a magnetometer calibration and calibration method is provided,After calibration,the magnetometer is applied to the initial alignment of MEMS inertial navigation system.
