Iterative calibration method for inertial and magnetic sensors

Authors: Eric Dorveaux, David Vissière, Alain-Pierre Martin, Nicolas Petit, 48th IEEE Conference on Decision and Control, December 16-18, 2009, Shanghai, pp. 8296-8303 DOI: 10.1109/CDC.2009.5399503
We address the problem of three-axis sensor calibration. Our focus is on magnetometers. Usual errors (misalignment, non-orthogonality, scale factors, biases) are accounted for. We consider a method where no specific calibration hardware is required. We solely use the fact that the norm of the sensed field must remain constant irrespective of the sensors orientation. The proposed algorithm is iterative. Its convergence is studied. Experiments conducted with MEMS sensors (magnetometers) stress the relevance of the approach.
