REAL TIME LOCATION SYSTEM AND METHOD USING RFID TAGS WHICH RELAY GPS SIGNAL

摘要

PURPOSE: A real time location tracking device using a GPS(Global Positioning System) signal relay tag and a method thereof are provided to find the location of a tag with low power by relaying a GPS signal. CONSTITUTION: A GPS signal relay tag(120) is located in connection with an object. The GPS signal relay tag is in connection with receiving a GPS signal from an artificial satellite. The GPS signal relay tag transmits the received GPS signal to a reader(130) installed in a base station or a wire/wireless line sharer. The GPS signal relay tag enables the reader to calculate a location coordinate about the object.
