Mr Revhead wrote:So, your average speed between two points. I would assume those two points would depend on how many sattellites you're picking up at that time?
Not your realtime speed.....

If you're driving slowly, you cover say 5m in the time between two calculations and each calculation is off at the worst limits of accuracy it could think you've done 15m and therefore give you a 200% error in speed. If you're going so fast you've done 500m between readings (unlikely) then 10m difference in that distance will only give you a 2% error.
