Abstract:

The High Accuracy-Nationwide Differential Global Positioning System (HA-NDGPS) program provides the capability to broadcast corrections to the Global Positioning System (GPS) over long ranges to achieve a better than 10 centimeter (cm) (95 percent) accuracy throughout the coverage area. HA-NDGPS is currently undergoing a research and development phase. The signal is available for test purposes from Hagerstown, MD, and soon Hawk Run, PA. Application of this technology will provide advanced safety features for transportation, including lane departure warning, intersection collision warnings, and railroad track defect alerts. It also could be used for economic enhancements such as precision container tracking and automated highway lane striping. Currently, the GPS service offers a 4- to 20-meter (m) navigational accuracy. For many land transportation uses, this accuracy is insufficient. The Nationwide Differential Global Positioning System (NDGPS) offers a 1- to 3-m radio-navigational service that meets the needs of many more transportation users.
