Abstract: An Airport Guidance System and Method which provides for GNSS compatible seamless airport guidance capability is disclosed. The computer system provides a automated lighting functions based upon GNSS based position and spatially compatible databases. The system and method 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, zone-based automated airport lighting control, 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 lighting methods and processes are applicable to vehicles and aircraft operating in a controlled airport space envelope as well as other remote user sites with or without the assistance of air traffic controller.
