Abstract
A method and apparatus for determining the position of a RFID tag. The method includes the following: (1) measuring the position of an active device to an accuracy of better than 1.0 meter using a radio locating system to determine the position of a reference point; (2) detecting a first RF signal from a reference RFID tag near the reference point with an RF receiver in an RFID reading system; (3) detecting a second RF signal from a RFID tag of interest with the RF receiver in the RFID reading system; and (4) processing both the first RF signal and the second RF signal and relying upon at least partially the position of the reference point to determine the position of the RFID tag of interest.
