GPS in the Airport Environment - Runway Incursion Avoidance Using GPS

H. Robert Pilley and Lois V. Pilley

Abstract:	its recent GPS-based runuay incursion avoidance analysis and demonstration activities conducted at Manchester (NH) Airport. Based on the integration of enhanced GPS with highly accurate J-Dimensional airport msps, the Airport Control 8 Management (AC&M) System has the capability to provide all-weather air and ground navigation and control for a variety of vehicles within the airport terminal area. Real time collision prediction algorithms, based on the GPS inputs, are used to alert the pilot and Air Traffic Controller of potential incursions, collisions and off course conditions. The AC&M methodology supports the participation of various vehicle types. Vehicles are equipped with varying hardware and software configurations. Each vehicle is capable of receiving real time differential corrections and transmitting GPS based information. The enhanced GPS-based Position, Velocity and Time (PVT) information derived on board each vehicle is used to support mathematical algorithms compatible uith airport movement and management operations. These algorithms are used to predict projected positions for all equipped aircraft/vehicles based on their current velocity and heading. In this manner, potential collisions betueen moving vehicles and between moving vehicles and stationary objects may be automatically detected and reported. A key element of the Airport Control/Management System is the integration of GPS-based position data with a 3-Dimensional digital airport map. The GPS information derived on board each vehicle is transmitted via a datalink to remote display sites. When received by the remote users, the data is formatted and presented in a real time moving map display. This implementation of terminal area Automatic Dependent Surveillance (ADS) provides full situational auareness to the Air/Ground Traffic Controller(s) and other vehicle operators.
