GPS normally displays its range of precision, which depends on the number of
satellites that can provide a good signal at given conditions, i.e.
geographical position, obstructions etc.  I don't remember what is the
lowest precision of my Garmin Legend (when it still gives some location),
but must be better than 900m error of dead reckoning.  I've heard of
possible fog-induced distortion of signal, but haven't had a chance to check
it personally, so don't know whether it is just "honest" weakening of signal
(= honest lower displayed precision), or really distortion of data beyond
stated range of precision (this would be much worse).
