This paper presents the principle of the proposed elliptical fitting calibration algorithm and compares it to the published ellipsoidal fitting algorithm for correcting the orientation of magnetic measurement, yaw angle. Two algorithms are implemented on a real device which is the magnetometer in an ...
5) I have defined SIMULATION, so no calibration data is stored in or retrieved from flash and at start up the magnetometer buffer and the calibration algorithm seem to be correctly initialised. The loopcounter is set to zero. <-- it seems to me that there may be a potential problem if ...

Abstract In this work, an online calibration algorithm for strapdown magnetometers is proposed. The proposed method is based on the observation that the magnetometer's measurements are on an ellipsoid manifold. The algorithm is attitude independent and makes use of Extended Kalman Filter....
