In this paper, Radio Frequency IDentification (RFID) technology is used for localization system. The location of a RFID reader is estimated based on the known locations of RFID tags using the UHF band RFID system. The new location estimation method based on the angulation technique is proposed to determine the reader location in real time. For angulation technique, the RFID reader is held on the camera tripod and it is considered as the target to be localized. The passive tags are attached at the known location and considered as the references.
