Abstract

This paper presents a real-time calibration algorithm for tri-axial magnetometer. A non-linear state space model for calibration related parameters is derived by the invariance norm of local geomagnetic field, and cubature Kalman filter (CKF) is used to estimate calibrating parameters in sequential manner, which is more suitable for real-time critical applications. The effectiveness of the algorithm are verified by numerical simulations. The results are compared with the traditional TWO-STEP algorithm, and the corresponding conclusions are obtained.
