Abstract

A method for correcting an orientation of a magnetometer includes obtaining current position information through a global positioning system. A geomagnetic inclination angle list is queried according to the current position information to acquire a geomagnetic inclination angle δ corresponding to a current position. A deviation Δψ of an orientation is calculated according to the geomagnetic inclination angle δ and the orientation is corrected based on the deviation Δψ of the orientation.
