DGPS For Seamless Airport Operations

Lois Valliere Pilley and H. Robert Pilley

Abstract:	Differential GPS will play a key role in the seamless automation of our airports and Air Traffic Control (ATC) system. DGPS position, velocity and time (PVT) data will provide aviation users with world-wide, all-weather navigation capabilities, including precision approach. An integrated datalink will give all participants a dynamic view of the airport and provide ATC with the inputs it needs to generate efficient routing and scheduling information. Safety improvements will be realized through the constant 4-dimensional (4-D) monitoring of all air and ground vehicles to prevent potential runway i ncursi ons and collision conditions. This paper describes the prototype GNSS/ADS-based seamless airport navigation, control and management system developed by Deering System Design Consultants, Inc. (DSDC) at the Manchester, NH airport. Beginning with the earliest GPS-based airport surface operation tests, DSDC’s efforts have broadened to include DGPS-based precision approach and runway incursion / collision avoidance for air and ground vehicles. The results of these ongoing tests have shown the strengths and versatility of an integrated DGPS/datalink system. Using local differential corrections broadcast to surf ace vehicles and aircraft, the following airport functions have been successfully demonstrated: * ADS-based situational awareness at ATC * ADS-based situational awareness in vehicles * Collision detection (ATC and vehicles) * 3-D runway and zone detection (ATC and vehicles) * Precision approach and map navigation (vehicles) * Mirrored navigation at ATC * Automated lighting control based on vehicle position and clearance status This paper discusses the techniques used in DSDC’s research efforts and the benefits of a DGPS-based system for future airport navigation and surveillance.
