HIGH ACCURACY-NATIONWIDE DIFFERENTIAL GLOBAL POSITIONING SYSTEM PROGRAM FACT SHEET
The High Accuracy-Nationwide Differential Global Positioning System (HA-NDGPS) program provides the capability for broadcasting corrections to the Global Positioning System over long ranges to achieve a 10-cm (4-in.) accuracy throughout the coverage area. HA-NDGPS currently is undergoing a research and development phase. The signal is being tested in Hagerstown, Maryland, and soon Hawk Run, Pennsylvania. Application of this technology will provide advanced safety features for transportation, including lane-departure warnings, intersection-collision warnings, and railroad track defect alerts. The technology also could be used for economic enhancements, such as precision container tracking and automated highway lane striping.
