No global position

log link:

“No global position” often occurs after multi rotor is converted to fixed wing in mission mode.

Is it geomagnetic interference? Or vibration?

code basic(v1.11.2)

By the way, we have tried to transmit five times on another vehicle with basically the same structure, but this problem has not happened.

Today we will try to recalibrate geomagnetism and hope to have good results

Why it’s happening im not sure but loss of global position is usually gps related.

Increase COM_POS_FS_EPH. That’s a bandaid but will possibly fix this for you.
