Vehicle location determination system using an RFID system
First Claim
1. A vehicle location determination system, comprising:
- a) a radio frequency identification (RFID) interrogator system positioned on a vehicle; and
,b) a plurality of passive RFID tags each having a unique tag ID containing encoded information which can be decoded without reference to a database, said RFID tags being positioned in an environment proximate to an intended path of said vehicle,wherein said RFID interrogator system provides the capability of determining the location of the vehicle in said proximate environment based on the interrogation of said passive RFID tags.

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.

12. A system for locating the position of an aircraft in an airport surface movement area, comprising:
-
a) a radio frequency identification (RFID) interrogator system positioned on an aircraft; and
,b) a plurality of passive RFID tags positioned in an airport surface movement area of an airport each having a unique tag ID containing encoded information which can be decoded without reference to a database, wherein said RFID interrogator system provides the capability of determining the location of said aircraft in said airport surface movement area based on the interrogation of said passive RFID tags, thus providing enhanced situational awareness to pilots as to their position in the airport. - View Dependent Claims (13, 14, 15, 16, 17)
