A method for real-time compensation of magnetometers embedded on smartphones

摘要

This paper deals with a real-time compensation method of long term time-variant disturbances for magnetometers embedded on smartphones. The proposed method compensates the effect of long term time-variant disturbances, continuously, using a least-square ellipsoid-based compensation procedure. In this paper, the proposed method is described and its advantages respect to the methods available in literature are highlighted. Furthermore, preliminary simulation tests have been performed and the obtained results reported.
