RELAY TAG, LOCATION COMPUTATION READER, CONTINUOUS INDOOR AND OUTDOOR REAL-TIME LOCATION TRACKING METHOD AND SYSTEM USING GLOBAL POSITIONING SYSTEM (GPS) SIGNAL AND WIRELESS COMMUNICATION

摘要

Disclosed is a relay tag, a location computation reader, and a continuous indoor and outdoor real-time location tracking method and system, which tracks locations of a plurality of target objects of location tracking with a plurality of relay tags, in real time, wherein a GPS satellite transmits a location information signal outdoors, a similar GPS signaler generates a location information signal indoors, and transfers the generated location information signal, the plurality of relay tags, attached to the plurality of target objects of location tracking, relay the location information signals by receiving the location information signals transferred from the GPS satellite and the similar GPS signaler, and a location computation reader receives the location information signals from each of the plurality of relay tags, and computes locations of the plurality of target objects of location tracking.
