- 37 Nationwide Differential GPS Sites Shut Down, Leaving 46 Operational (Sep 19) On August 4, the U.S. Department of Transportation (DOT) and the U.S. Coast Guard (USCG) ceased broadcasting from 37 sites of the Nationwide Differential Global Positioning System (NDGPS). Fielded in the 1990s, NDGPS service augments GPS by providing increased accuracy and integrity using land-based reference stations to transmit correction messages over radiobeacon frequencies. Due to the improved accuracy of standalone GPS, and with the availability of other GPS augmentation solutions, the government decided to downsize NDGPS, eliminating the inland component and providing single coverage of coasts and waterways. The decision was reached after reviewing public comments on several Federal Register notices issued by DOT and USCG.
