Q.1 : Position GPS failsafe not activated
We had a crash a few days ago where the drone lost all the satellites of the primary GPS (ublox F9P) and started to go off in all directions. The root cause is known: it’s the antenna screw that unscrewed and cut off satellite signal reception.
My question is why, in such an obvious case of loss of position, didn’t the Position failsafe activate? We also have a secondary GPS and it was not used even though reception was good for it. Open issue here.
