Re: Invalid GPS coordinates in GPX export from GoPro 6

A further problem I'm facing are coordinate which are completely off track.

 

BIN file:

This is the GPX track I'm getting:

The tracks looks "exploded" in a few places:

This part here is completely off the track. Quite sure I did not drive there:

Same here:

Check the "vertical" part here in the middle. Looks quite consistent. Except there's no road there and I did not drive there. Also consider the part in the upper right corner.

 

I also get severely inprecise coordinates along the track:

Quik shows a somewhat better looking track:

However Quik does not show almost the half of the drack I actually drove.

 

I don't think these "explosions" of the track can't be explained by the imprecision of GPS. Ok, I'm fine with a few meters, but I see jumps of several hundreds meters if not kilometers here. Also, this is not visible in Quik.
