PND repositioning detector for better navigation accuracy in a car
Abstract:
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.
Abstract(Chinese):

一种用于个人导航装置的装置和方法，包括用于提供导航指导信息的个人导航装置（PND）。 PND可以包括用于感测由磁体产生的磁场的磁通量幅度的单维磁检测器。 或者，PND可以包括三维磁性检测器和用于确定表示PND的即时环境的环境磁场校准值的磁性校准模块。
