Not random ordinates, unpredictable offsets, apparently on the order of a kilometer.<p>And it wasn&#x27;t precision they were after at all.  You could just make a global positioning system arbitrarily less precise but that isn&#x27;t useful.  Kilometer precision doesn&#x27;t have much use to civilians, they need meter-precision at least and repeatable at that. What they were after was unpredictable but static accuracy offsets which presumably could be altered in a crisis.
