PND REPOSITIONING DETECTOR FOR BETTER NAVIGATION ACCURACY IN A CAR |
摘要 |
An apparatus and method for a personal navigation apparatus comprising a personal navigation device (PND) for providing navigational guidance information. The PND may include a single-dimensional magnetic detector for sensing magnetic flux amplitudes of a magnetic field generated by a magnet. Alternatively, the PND may include a three-dimensional magnetic detector and a magnetic calibration module for determining an ambient magnetic field calibration value representing immediate surroundings of the PND. |
