This paper proposes two methods for calibrating triaxial magnetometers. Both of them calibrate these sensors with more general assumption of noise on three axes than previous state-of-the-art methods. The first method estimates bias and rotation parameters more accurately and the second method yields a better estimate for the scaling parameter than the state- of-the-art method subMLE. The computational time of the latter is also 43 times faster than subMLE, which allows this method to be applied in devices with low-computational resources (e.g. smartphones). Furthermore, the second method yields more robust heading angle estimates compared to subMLE. This result implies that the second method can be applied in light-weight inertial measurement systems, for which the orientation of the device is vital information for pedestrian dead reckoning system.
