Abstract

An Airport Control and Management Method for use by an air traffic controller which provides for a GNSS compatible computer processing environment which supports airport control and management functions in the air and on the ground. The computer system provides for automation and a computer human interface supporting air traffic controller functions. The processing environment is based upon GNSS compatible position, velocity, time information and GNSS spatially compatible databases. The computer human interface combines the data entry role of issuing clearances with automated routing, conformance monitoring and lighting control functions. The system and methods utilize precise GNSS compatible zones, the Earth Centered Earth Fixed (ECEF) WGS-84 coordinate reference frame, GNSS compatible local coordinate frames such as local and state plane grids, travel path information management processes which allow for the intelligent control of airport lighting systems. True airport independent processing is achieved when the ECEF coordinate reference frame is utilized. The system utilizes broadcast Automatic Dependent Surveillance (ADS) information from participating aircraft and vehicles Although the processing methods may be employed using other surveillance information derived from radar ot multi-lateration sources with some degradation in performance due to radar inaccuracies and inability to produce accurate 3-dimensional GNSS compatible velocity. Radio receiving equipment receives the broadcast ADS information which is then supplied to the computer system. The computer system utilizes GNSS compatible position and velocity data to control the operation of airport lights using zone incursion processing methods. The methods and processes employed provide a fundamental framework for increased airport safety, operational efficiency, energy savings and improved automation resulting in reduced controller workload.
