Three-axis fluxgate-type magnetism detecting device and method
Abstract
A three-axis fluxgate-type circuit having three fluxgate sensors for outputting three analog voltage values respectively. A controller normalizes three digital voltage values corresponding to said three analog voltage values, select a set of linear voltage values from the three normalized digital voltage values and calculate an azimuth based on the set of linear voltage values.
