摘要：A geomagnetic sensor which informs a user that information with respect to adistorted azimuth angle may be detected. The geomagnetic sensor includes a

geomagnetism detection module including an X axis fluxgate and a Y axis fluxgateorthogonal to each other and detecting a predetermined amount of electrical signalscorresponding to a geomagnetism of each of the fluxgates; a signal processing unit forconverting the electrical signal output from the geomagnetism detection module topredetermined X axis and Y axis output values and outputting them; a display unit fordisplaying 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 controllingthe display unit to display the predetermined warning message upon determination thatthe output values are distorted. Accordingly, the possibility of a distorted azimuth anglemay be detected and informed to a user.
