双三轴正交测量系配准误差建模与校正研究
|
摘要
捷联式电子罗盘是一种利用地球磁场测量方向的系统,它是一个双三轴传感器测量系统。随着应用领域的拓宽和技术的发展,对罗盘的精度要求越来越高,在现罗盘硬件确定的条件下,要提高罗盘的精度,就要对两个传感器进行配准。通过采用坐标转换原理进行配准误差建模,用常用于地球物理学的反演算法,对误差进行估计和修正,最终实现罗盘传感器的配准标定。实验仿真表明,该法能明显的提高罗盘的精度。
Strap-down electric compass is a system that uses the earth's magnetic field to measure heading.It is a two triaxial intersections sensor measurement system.With the development of technology and application,high precision electronic compass is requested.When hardware is fixed on,in order to improve precision of the electric compass system,the registration of dissimilar sensors is in need.Coordinate rotation and inverse arithmetic were applied to establish and estimate an error model,and then the error mode was used to correct heading,thus to finish the registration and calibration of the electric compass.Experimental simulations show that this method is effective in improving the precision of the electric compass.
