ABSTRACT:
A geomagnetic sensor which informs a user that information with respect to a distorted azimuth angle may be detected. The geomagnetic sensor includes a geomagnetism detection module including an X axis fluxgate and a Y axis fluxgate orthogonal to each other and detecting a predetermined amount of electrical signals corresponding to a geomagnetism of each of the fluxgates; a signal processing unit for converting the electrical signal output from the geomagnetism detection module to predetermined X axis and Y axis output values and outputting them; a display unit for displaying a predetermined warning message on a screen; and a control unit for determining whether the output values of the X and Y axes are distorted, and controlling the display unit to display the predetermined warning message upon determination that the output values are distorted. Accordingly, the possibility of a distorted azimuth angle may be detected and informed to a user.
