"In the new system, 25 ground stations constantly check the accuracy of the GPS signal. Software corrects glitches caused by things like atmospheric disturbances, and the stations beam corrected information to pilots via a pair of satellites. After seven years of trying, Raytheon of Lexington, MA, is expected to deliver the system as early as March 2003, the FAA says."
