Submission + - Is National Differential GPS lost?
Nealix writes: This article NDGPS led to the budget chop block at GPSWorld mentions that National Differential GPS (NDGPS) may be endangered in the 2007 budget. This has ramifications for a variety of other government projects such as the Intelligent Transportation System (ITS) and Positive Train Control (POT) by the Department of Transportation. Blind people and robots would also benefit from highly accurate GPS navigational capability provided by NDGPS, which appears to work better in the urban canyons. The article also continues the NDGPS vs. WAAS debate. Of course, what would be really cool is to see more GPS sites around the country make DGPS data (RTCM) available over the Internet.
