摘要: The invention provides a magnetic compass calibration system which compensates for permanent and induced magnetic fields of a vehicle in order to provide an accurate heading indication, wherein x and y magnetometer values are processed in accordance with an algorithm in order to update calibration whereby calibration can be effected without performing a specific manoeuvre such as causing the vehicle to circle through 360°.
The compass is suitable for use in a navigation system using the dead reckoning technique.摘要翻译: 本发明提供一种磁罗盘校准系统,其补偿车辆的永久和感应磁场,以便提供准确的航向指示,其中根据算法处理x和y磁力计值,以便更新校准,由此校准可以 在不执行特定操作的情况下进行,例如使车辆循环360度。 指南针适用于使用航位推算技术的导航系统。
