Matlab-based method for magnetometer calibration

Abstract

Magnetometers are essential components of any reliable Attitude and Heading Reference System. The advent of low-cost MEMS based sensor technology made their use more widespread than ever with applications ranging from hobbyist drones to automotive industry. Most low-cost MEMS magnetometers available on the market fall into consumer grade sensors. This makes the need for simple calibration techniques more relevant as it provides a means of trading cost for improved performance and accuracy. In this thesis, a MATLAB-based method for magnetometer calibration is proposed and discussed along with experimental data and possible applications.
