I am in the process of building an indoor drone. For this, I am using a UWB system (Marvelmind Superbeacons). I have set everything up, and the beacons on the drone are working. In Mission Planner, the GPS is also displayed (GPS: 3D Fix). The direction of the drone (Yaw)
is also provided by the beacons. The AltHold mode works as well. However, when I switch to Loiter or Position Hold mode, I get the message “Prearm Need Position Estimate.”
What could be causing this?
Attached are all the parameters.
