Can u clarify? I know when I switch the GPS on I set it to a starting position (my home airfield). Is this what you are referring to? I had thought that with enough satellites (4 or more IIRC) you could always be located on one point where all the circles intersected on the surface of the earth (ok.. you may be at 2000ft or whatever.... but close enough in this context). I'm certainly not an expert in GPS! So maybe I'm talking Ball-socks?
Sorry for the thread hijack by the way!
