Thanks a lot ed! Having a gpx extract is great (I'm currently playing with it). Yes, 'hdop', 'fix' and 'sat' are the 3 main fields I need for precision. What is "course"? I found "Instantaneous course at the point" (in degrees) [1] but I do not understand.
Anybody could confirm that GTA04 gives this as well? (I've just asked the gta04-owner list too). Also: What about orientation? Thanks!
