First Claim
Patent Images
1. A real-time location tracking apparatus using a global positioning system (GPS) signal relay tag, the apparatus comprising:
- a tag, positioned in relation to an object, to work conjunctively with a GPS signal received from a satellite, to transmit the received GPS signal to a reader installed in a base station, a relay station, or an Access Point (AP), and to enable calculation of location coordinates of the object by the reader.
