This gets you close enough to vaporize your target. I was involved in marking locations at a shipping port so we could keep track of the location of each container. Took a while to get the data, but very much improved the location checkers job.

Hi freserf, so I'm just trying to understand, are you trying to theorize a more accurate approach to operating an odometer than what the 986 uses?
The 986 literally uses a sensor that counts rotations and multiplies that by a constant, some statistically validated constant, that attempts to account for the variable diameter of all possible tires offered on the vehicle. It is not complex at all. Most other vehicles also use this method.
