tracker 20 on Fjalls is still moving progressively in a straight line. It has risen in altitude too. Recent cold weather has stopped solar charging but it is still sending good data. I have deleted fix outliers as it moves less than 5cm but sometimes gets a 1m error.

the tracker had a “glitch” in january – perhaps tilting for a short period or some GPS-related issue – hence the “step” seen in the plots in January.
