摘要

对电子罗盘磁差补偿的椭球拟合校准法进行深入研究

并分解为硬磁、软磁、比例系数校准和未对准误差校准

分别进行仿真分析

直观给出各部分磁差对拟合后的椭球拟合影响。与工业级高精度HMR3300型电子指南针进行对比实验

给出基于HMC5883L磁阻传感器的自制电子罗盘经过椭球拟合校准后的导航精度。

Abstract

Ellipsoid fitting calibration method used for magnetic compensation on electronic compass is researched

decompose the algorithm into four parts which are hard-magnetic

soft-magnetic

scale coefficient and misalignment error calibration

and simulate and analyze effect of magnetic error of each part on ellpsoid fitting is proposed vividly.Use HMR3300

navigation precision of electronic compass is given

to compare with HMC5883 L which is manufactured in the lab

and the result is satisfied.
