In my moves in alps I have a lot of times troubles with gps track. Look on link below:
DejanGr's 7:10 h Mountaineering Move
In this case I go back from top of the mountain on the same way that I climb on it.
The track should be the same in both directions, but it isnt. Watch was recorded the right gps track only from the top to the starting point.
I use best gps accuracy (1 sec interval) and gps position format is set to WGS84 Hd.d (default).
I have this trouble only when mountaneering in alps.
It look like gps signal in certain points is weak, or maybe something else is quilty for this inaccuracy (or that is normal) ???
Any ideas, many thanks.
