Abstract

Bias drift due to temperature change in geomagnetic sensors which is used in the micro attitude heading reference system has been investigated.Based on frequency spectrum analysis on the noise

a band-stop digital filter is designed to reduce the effect of noise.The relations between temperatures and sensor outputs is presented and a real-time compensation model based on polynomial cancellation is established and used in the micro attitude heading reference system to reduce the error due to temperature drift of the geo-magnetic sensors.The test results show that the repeatability of zero offset error of geomagnetic sensors is good

and that the real-time temperature drift compensation model can effectively reduce the error due to temperature of geomagnetic sensors and the preheating time and improve the accuracy of the system.
