摘要： A geomagnetic application device including a triaxial magnetic sensor, a measurement point acquiring mechanism, a calibration mechanism calibrating offset of the magnetic sensor, and an azimuth calculator. The calibration mechanism includes an offset calculation measurement point selector selecting at least six measurement points of the geomagnetic vectors from among a data set stored in the measurement point storage unit by the measurement point acquiring mechanism and storing the selected measurement points in an offset calculation measurement point storage unit. The offset calculation measurement point selector selects the measurement points from among the data set stored in the measurement point storage unit to include at least six points, component values of which are maximum or minimum in each of three orthogonal axes.
