Coast Guard winds down Differential GPS

 First deployed in 1999, the Differential Global Positioning Systems (DGPS) correct for slight discrepancies between signals from GPS satellites and actual ground locations. Subsequent enhancements in GPS capabilities have since rendered the corrections unnecessary, the Coast Guard said, as DGPS has narrowed accuracy from 40 meters to the present 7.8 meters as estimated by the official GPS.gov website. http://www.c4isrnet.com/story/military-tech/omr/satcom/2015/12/07/coast-guard-winds-down-differential-gps/76931118/
