  • Publication number: 20110063166
    Abstract: A positioning data producing unit can select suitable region position units automatically in accordance with the environmental conditions of the moving target. The location information of a position tracking device is calculated either from a coordinate data of a narrow region and a position data of the narrow region which is selected in accordance with a location of the position tracking device, or from a position data of a broad region, wherein the position data of the narrow region is calculated from a movement parameter of the position tracking device, the position data of the broad region is calculated from a plurality of received satellite signals. The location information is then transmitted via a communication module to a far end receiver.
