Abstract: A geomagnetic sensor for auto-calibration of a deviation and a method of using the geomagnetic sensor. The geomagnetic sensor includes a geomagnetic detector including X-axis and Y-axis fluxgates orthogonal to each other and receiving a drive signal to detect an electromotive force corresponding to a geomagnetism, a signal processor converting the electromotive force output from the geomagnetic detector into X-axis and Y-axis output values and outputting the X-axis and Y-axis output values, and a drive signal generator applying the drive signal to the geomagnetic detector. Each of the X-axis and Y-axis fluxgates includes cores, a solenoid type exciting coil, and at least two detection coils winding around the cores in a solenoid form. Accordingly, as an azimuth is measured using output values detected by the separated detection coil, the azimuth can be exactly and easily detected regardless of an external magnetic field.

Abstract: A geomagnetic sensor supporting a dip angle detection function. The geomagnetic sensor includes a rotation angle measurement part for measuring pitch and roll angles of the main body with respect to the surface of the Earth; a geomagnetic measurement module for outputting an electric signal corresponding to the geomagnetic field; a memory for storing predetermined reference azimuths and output values of the geomagnetic measurement module corresponding to changes of the pitch and roll angles; and a controller for calculating azimuths by use of the output values of the geomagnetic measurement module, the pitch and roll angles, and predetermined dip angles. The controller establishes at least two dip angles, calculates the azimuth for each dip angle, compares the azimuth to the reference azimuth, and determines a dip angle at the azimuth having a smaller azimuth error as a current dip angle.
