摘要： A fluxgate sensor is integrated in a printed circuit board. The fluxgate sensor has two bar-type(or rectangular-ring shaped) soft magnetic cores to form a closed magnetic path on a printed circuit board and an excitation coil in the form of a metal film is wound around the two bar-type soft magnetic cores either in a united structure that winds the two bar-type soft magnetic cores altogether, or in a separated structure that winds the two bar-type soft magnetic cores respectively, both in a pattern of number ‘8’. A pick-up coil is mounted on the excitation coil, either winding the two bars altogether, or respectively, in a solenoid pattern. The fluxgate sensor integrated in the printed circuit board can be mass-produced at a cheap manufacturing cost. The fluxgate sensor also can be made compact-sized, and at the same time, is capable of forming a closed-magnetic path. As a result, flux leakage is minimized, and the fluxgate sensor has a high sensitivity as it detects the magnetic field through a variable driving.

摘要： 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.
