Abstract

This invention relates to the method of adjustment of orthogonal normalization in a 3-axis magnetometer, where the three axes fail in achieving a full normalization because of axial errors during making the 3-axis magnetometer, to make the responses of the 3-axis of the magnetic meter magnetometer completely orthogonal and normalized. The invention is based on the vector projection concept by detecting a 3x3 matrix data in a standard magnetic simulator before using an inverse matrix to obtain the orthogonal normalized compensation coefficient of the 3-axis magnetometer. The compensation coefficient may be achieved by means of an analog electronic compensation circuit or table index storing with a micro-computer or a signal processor for the calculation, for successful adjustment of the orthogonal normalization of the 3 axes at the same time.
