Method for correcting orientation of magnetometer and magnetometer

The embodiments of the present invention disclose a method for correcting an orientation of a magnetometer and a magnetometer, and relate to the field of positioning technologies and solve the problem that in the process of correcting an orientation of a magnetometer, a geomagnetic inclination angle ´ acquired is inaccurate and the accuracy of data provided by the magnetometer is influenced. The method provided by the present invention includes: obtaining current position information through a global positioning system, querying a geomagnetic inclination angle list according to the current position information to acquire a geomagnetic inclination angle ´ corresponding to a current position, calculating a deviation È of an orientation according to the geomagnetic inclination angle ´ , and correcting the orientation based on the deviation È of the orientation. The embodiments of the present invention are mainly used in the process of correcting an orientation of a magnetometer.
