System for determining the position of vehicles at an airport
First Claim
1. Device for determining the position of an aircraft at an airport, comprising a plurality of sensors for detecting at least one radio signal originating from a vehicle, the plurality of sensors (5) being positioned on parts of the airport which are accessible to the vehicle, characterised in that the at least one radio signal originates from a radio altimeter (12).

Abstract
Device for determining the position of an aircraft (11) at an airport, includes a plurality of sensors (5) for detecting at least one radio signal originating from a vehicle (11), in which the plurality of sensors (5) are preferably positioned at regular intervals from one another on parts (2, 3) of the airport which are accessible to the vehicle (11). The present device is preferably used for detecting the position of an aircraft (11) on the runway system of an airport. The sensors (5) are preferably fitted in light positions of runway lighting provided at the airport on taxiways, take-off and landing runways (2, 3) and on plat-forms. The signal originating from a radio altimeter (12) of an aircraft (11) is preferably used as the radio signal.

12. Device for determining a position of an aircraft at an airport working in conjunction with a radio altimeter installed in the aircraft, comprising:
-
a plurality of sensors located at regular intervals along a center line of airport taxiways and configured to receive a downwardly directed signal from the altimeter;
plural local processors, each local processor connected to process signals received by a corresponding sensors;
plural communications units connected to receive signals from the local processors; and
a central processing unit connected to receive signals from the communication units, the position of the aircraft being determined by the central processing unit with reference to a measurement using signals from at least one sensor. - View Dependent Claims (13, 14, 15, 16, 17)
the sensors are integrated with the local processor for analysis of received signals and for data communication, the local processor comprise a filter for filtering signals originating from the sensor so that a strength and a direction of filtered signals are analysed for plural frequency bands, and the local processor determines the individual strength and direction of the received signal from each of the frequency bands.
