Trig on stop: OFF - But still..

[porakone]

I have a slight problem with my tracker, it seems to trigger sometimes with no obvious reason at least not obvious to me. The only trigger I've set is distance 250 metres and the idea was that when ever I park my car, the last position sent will be the last position shown until I continue driving and exceed the 250 meters and the new location would be sent.

Let's say that I come home and check my Buddytracker. It shows my location for example 150 meters away from home, just like it should. But sooner or later (can happen in a few minutes, may take a few hours) I have a new location right at my door at least very close to it. The idea for the triggering setup is just that it doesn't display my exact stopping point but it just keeps on doing that.

First I thought that the gps has had some fail locations and it thinks I've been driving around, but when I check my tracks in Buddytracker there's just a straight line from the 'previous 150 meters away spot' to my door step.

What could be doing this?

I'm having some restarting problems with my N96, it can sometimes restart up to 4 times in 20 minutes while running the Tracker (and that's all what it's for, has been factoy reset and nothing else done than the tracker installed) so that was my first idea to be the reason. But then I turned on the 'sms after activation' (or something like that) to see when ever it/the tracker restarts and found out that the restarts and the unwanted triggerings aren't related.

Edit: Sometimes the triggering occurs during the restart but as I said, not allways. Don't know if it triggers or restarts first.

Why the distance trigger works like you described? I have not much to add to your analysis.

GPS errors (reflected signals etc) would be one possible cause, but then the locations should sometimes be off the straight line. The GPS is quite accurate most of the time (error is less than 10 meters under open sky), but sometimes the fixed position can wander significantly more than 250 meters, especially if the view is limited to the northern sky (here at the northern latitudes).

The frequent N96 restarting does not sound to be normal and this is an obvious explanation to some of the strange behaviour you have observed. Have you updated your firmware?
