Did not calibrate on location (P4 didn't ask for it as i usually does) Flew a few miles from the place a couple of hours earlier without problems.
All software and firmware was up to date
I deleted the two failed plans - I plan to try again tomorrow morning. I've made two new vaarstvej vest and vaarstvej east
There was a thunderstorm 10 kilometers away - I suspect that that might have had some influence - but I don't know. Flying manually later I lost GPS twice as well.
There is no wifi in that area
I'll make at test in another area in which I've flown before without problems before I go back
