Jeff its really a shame you have to continue explaining yourself to this moron. A posting to him is a dead frog in science class. I really dug into the relay posts and after playing with a GPS device the last 5 months myself I can see it will not be used for anything related to train signalling, safety and position. Shown bottom a typical handheld using Mapsource software shows the eastbound and westbound Kearny area at Hudson Yards from PA rails on three round trips. I'm not sure what type of GPS Terripan STation uses but I recall having a discussion over speed clockings with this as well being plus or minus 5 MPH. Had a friend in DOT try out a new radar gun to callibrate a speeodometer mod for me. Off over 7 MPH. Takes almost 40 seconds for the 17 satellites to even lock in and other GPS receivers don't fair much better today. To be 15 feet off and only work outdoors will help lost motorists and hikers. Not railroads.
