Reply to "Surfing for GPS"

alanjonesMember

Just to back up what Pete has found, the study done in Australia comparing Differential GPS with the Jones-Oerth Counter, had problems when the course ran underneath trees. They showed a map of the course as GPS thought it went compared to where the road really is. Where there were trees, there was often quite a deviation. And, remember this is Differential GPS which is much more accurate than the normal, off-the-shelf, GPS.
