The number of sats doesn't matter as much as how far apart they are, I'm not sure if the weather you are thinking of would have as much of an effect as you think it would, unpredicatable changes in the ionosphere is another matter but I doubt you can see these. Number of sunspots, since it's an indication of output from the sun, of late, well last couple of years there has been less and less activity/output from the sun. Also it's not just about the accuracy of a chip, but also the sensitivity, knowing what device would also give you an idea of the antenna as well, so yes knowing what device, not what chip, recorded a track would be useful. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
