>> That's my understanding as well. The distance between A and B isn't a _factor_ in GPS measuring. It's a _result_ of it. Figure the position of A, figure the position of B, then calculate the distance between 'em. Your calculated figure will differ from the actual figure obtained by traveling from A to B by 1mm (or less) per 96km of distance. << Right, that makes sense, but I still don't see how it is distance dependant! Each point will be off from some theoretical point to a certain degree, this error does not depend on any other measurements you do or do not make, and thus, any two points anywhere in the world will have the same degree of relative inaccuracy! (Or so I would have thought, but since I don't know what I am talking about…..<g>) GTL
