Thanks Sparkle, I'll try different leg-time.Hi Lucky:
I'm certainly no expert, but:
Your trackpoints are very close together and only 5 secs apart. The GPS is trying to interpret the track based on rapidly changing (ambiguous) directions in a short period of time and distance, (ie 5 seconds and around 7 meters).In such a short distance the GPS would interpret any small change in direction and estimate it to make the track.
It appears you were moving very slowand if you're going to use it while moving at a slow speed set the trackpoints timebase to a longer period, so the machine can do the calculation based on more information. According to your chart there was considerable variation in the direction as you moved that wouldn't happen on a motorcycle or car at higher speed.
A GPS calculates position based on changes from one point to another, and the more datait can collect andaverage the more accurate the track.
I think...
