Error Analysis and Algorithm Validation of Geomagnetic Sensor

Abstract:

Based on the fundamental principle of magnetic compass, the effect of interference and sensor errors on the magnetic azimuth measurement accuracy are analyzed. In order to eliminate the influence of geomagnetic sensor system error interference sources effectively, the paper puts forward a method of obtaining accurate heading angle and azimuth of magnetic compass, which is realized by converting magnetic components in the space coordinates to horizontal coordinate as well as adding an algorithm of eliminating carrier interference and software filter. The test of application system shows that data errors are greatly reduced after adding the anti-interference algorithm. The system testing errors is almost equal with Xiaomi phone at the same condition. It proves that this system is applicable to general navigation field.
