PreArm: Need position estimate in guided mode

Hi @NK_AA ! The problem seems to be similar to your other thread. It’s better continue there.

Failed to change to loiter mode from stabilize mode - "requires position"

Hello,all. We tried autonomous flight using raspberrypi and dronekit. The sequence is written below (now we do not attach propellers). Change to stabilize mode, armed, change to loiter mode, take off, hovering, change to guided mode, and land after my quad arrived at our goal. When we remove ‘change to loiter mode’, the sequence works well. What is the our problem? What we should do? Please teach me.
