Uh... Correct me if I'm wrong, but If this was the case, a moving tracker
would give away it's location simply by using the center of the circle.
Actually, so would a stationary one if it was truely given a circle shape. And
besides, this is much more math. Truncation of lat/lon is a trivial
As it is, the truncated-fix ambiguity does this to a much lesser degree for
a moving tracker as the square jumps when crossing the lat/lon lines.
