Abstract A position tracking device for mobile in which the course of an arbitrary mobile carrying a device or installed with a device is tracked. The inventive device comprising a satellite positioning system, periodically measures/generates a signal representative of current geographic position of the device, supplies that signal to a microprocessor for tagging the signal with time, and records positional and time information for which correlation is operated in a nonvolatile memory. A fixed unit retrieves the positional and time information directly from a mobile position tracking device or through a radio modem and processes trace of the course of mobile or information for generating printed data clarifying the course of mobile.
