"Nationwide DGPS: The Department of Transportation is currently fielding the Nationwide Differential GPS (NDGPS) network to improve the accuracy and integrity of GPS for surface and maritime users across the United States to the 1-3 meter range. In addition, 34 countries around the world have already installed DGPS radiobeacon networks, and more are considering the adoption of this navigation standard. The improvement of the basic GPS signal through elimination of SA may allow the NDGPS radio beacons to transmit fewer error corrections and more value-added navigation messages, improving highway, railroad, and waterway safety. The range of individual NDGPS stations is also expected to increase, benefiting mariners farther off shore and opening the possibility of reducing the overall number of stations to be fielded. This flexibility allows for a more cost effective network for the government and the nation. In addition, the complexity of all DGPS systems will be reduced, lowering costs for those who will be using this technology."
