Runway Incursion Avoidance Using GPS

H. Robert Pilley and Lois V. Pilley

Abstract:	This paper sunnarizes DSDC’s airport research during its recent GPS-based rut-way incursion avoidance analysis and demonstration activities conducted at Manchester (NH) Airport. Based on the integration of enhanced GPS with highly accurate 3-DimensionaL airport maps, DSDC’s Airport Control/Management 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 and collisions. DSDC’s Airport Control/Management 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 information derived on board each vehicle is used to support mathematical algorithm cmtible with airport movement operations. These algorithm are used to predict project4 positions for all equipped aircraft/vehicles based on their current velocity and heading. In this manner, potential collisions between moving vehicles and between moving vehicles and stationary objects may be automatically detected and reported. A key element in DSDC’s Airport ControL/Management System is the integration of GPS-based position data uith a 3-Dimensional digital airport mep. The GPS information derived on board each vehicle is transmitted via a datalink to remote display sites. Uhen received by the remote users, the data is formatted and presented in a real time moving map display. This implementation of a terminal area Automatic Dependent Surveillance (ADS) provides full situational auareness to the Air/Ground Traffic Controller(s) and other vehicle operators.
