Patent abstract
A vehicle location determination system including a radio frequency identification (RFID) interrogator system positioned on a vehicle; and, a plurality of passive RFID tags positioned in an environment proximate to an intended path of the vehicle. The RFID interrogator system provides the capability of having the vehicle determine its location in the proximate environment based on the interrogation of the passive RFID tags. The present invention is particularly adaptable for use in an airport environment. It is not reliant on any type of ground based interrogation system. Instead, the airport surface movement area (i.e. taxiways, runways, ramps and gates) is only required to have a system of passive RFID tags.
