New satellites will only help to a point but basically what you are seeing is the inaccuracy of the GPS system (or at least the part we are allowed to use). If you don’t want to see the numbers jumping around we could back to using the “position pinning” software which we used long ago and most didn’t like. What we do now is report what the GPS Receiver is reporting to the unit as your current position. We could do like others and start doing estimates of your position, course and speed but enough Customers would have to ask for this and it could just as easily show you moving when you are not or not show you moving when you are. Just remember that any sort of blockage or reflection of the signal from all available GPS satellites will just make this worse.
