Abstract: The office of Aeronautical Charting and Cartography (NOS, NOAA) is responsible for the production and maintenance of aeronautical charts and chart related products. The maintenance of visual aeronautical charts is assisted by airborne surveys of charted areas within the United States. These surveys permit current inspection and editing of data portrayed on the charts. This paper describes the theory, development, and use of a Computer Generated Area Navigation (RNAV) Waypoint Grid System for airborne surveys. Control for these surveys is provided by aircraft equipment utilizing the VOR/DME navigation facilities of the National Airspace System. Bearings and distances (waypoints) from existing facilities are fed into RNAV equipment to create the survey grid. These waypoints are generated by a computer program using coordinate search and geodetic computation techniques from a navigation facility data base. The resultant waypoint grid data, in a form easily used in the aircraft’s RNAV equipment, provides accurate position and guidance information for the survey. This method may fulfill the control requirements for other airborne surveys.
