Brilliant. Can't believe I didn't think of it. In my old car when the speedometer and GPS didn't match up I always trusted the speedo. Eventually I went past enough speed checkpoints where I saw that the GPS always agreed with the radar to see I was wrong. Amazing that a couple computers a thousand miles off in space pinging away are more accurate than a physically connected system spanning mere feet.
