All of the matters described are possible at all times with a GPS system of position finding. However the notes that some accumulate errors are significant, and again may refer to particular firmware so that it will be difficult to determine the actual cause. 150m horizontal error, for example, across a time gap of a few hours, may well relate to changes in satellite position and reflection of signal occurring one one but not both times. Vertical errors are greater at all times. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
