Extension of aircraft tracking and positive identification from movement areas into non-movement areas
First Claim
1. A method for extending aircraft tracking from airport movement areas comprising one or more of taxiways and runways to non-movement areas comprising one or more of hangers, ramps and aprons, where aircraft position is previously detected and the aircraft previously identified in the movement area, the method comprising the steps of:
- detecting a signal from the aircraft,determining position of the aircraft from the signal from the aircraft,associating the signal from the aircraft with the previous identification of the aircraft by comparing the previous detected position of the aircraft with the determined position of the aircraft, andgenerating a track for the aircraft from a movement area into non-movement area using the signal from the aircraft.

Abstract
At most airports, responsibility of air traffic control starts and stops at the entrance or exit to the runway movement areas, which are taxiways and runways. In the non-movement areas, such as hangers, ramps, and aprons, aircraft movements and separation are no longer the responsibility of air traffic control, but is the responsibility of other parties such as the airport itself, airlines, or other parties. The use of tracking technologies for air traffic control is therefore focused on the movement areas, not the non-movement areas, where there are limitations in aircraft tracking. Furthermore, many of the aircraft transmitting devices are switched off in non-movement areas exacerbating tracking problems in these areas. The present invention includes several methods including broadband multilateration, to extend aircraft tracking from the movement areas into non-movement areas without the need to extend special air traffic control equipment into those areas.
