ABSTRACT:
Disclosed is a navigation apparatus and method using RFID that is capable of providing information on a current position and a moving direction to the destination. An antenna unit has directivity in a predetermined direction and receives at least one radio signal transmitted from at least one RFID tag. An RFID reader converts the at least one radio signal provided by the antenna unit into information on the at least one RFID tag in a digital form, measures the reception strength of the at least one radio signal, and provides the information on the at least one RFID tag and information on the received strength. A control unit determines the current position and moving direction on the basis of the information on the at least one RFID tag and the information on the reception strength provided from the RFID reader. Accordingly, it is possible to accurately recognize the current position and the moving direction of the navigation apparatus and guide the moving direction to the destination.
