@debubt What does the plot on the map in mission planner looks like? If it's displaying the same distortion, then the pixhawk is not correcting enough. Try increase P value for position. if it's displaying a different path then you see it has to be in the positioning itself. Please response with scr...

We fly in auto mode.

About EK3_GPS_TYPE:

Setting 0 = 3d velocity and 2d position. (Not 3d position!)
We don't want a calculated altitude but be as close as possible to gps measured height.

Rtl doesn't work for us either.

Also LAND instruction in a mission (waypoints) doesn't work.
We have only waypoints (and servo positions). Landing is done by going to 0m06. We than manually switch off with emergency stop (channel 8 in my params)

@freaad I don't completely understand what you say. I have following settings: EK3_ALT_SOURCE: Primary altitude sensor source Note: This parameter is for advanced users This parameter controls the primary height sensor used by the EKF. If the selected option cannot be used, it will default to Baro a...

@debupt The published code is all that I changed. It only stops measuring compass value and forces using predicted value for heading. And suppresses an error message. And adds an extra codition for arming. Uwb (pozyx?). I tried pozyx but the advantage of marvel mind is that is uses nmea protocol. As...

@easyaerial

Your marvelmind map is not on a zero degree north orientation.

Press the align button. Then beacon left under, beacon under right, beacon left up.

Your map needs to be to zero degrees.

Almost there!

I have seen this occur when power of modem radio was set too low.

Code to change compass from magnetic to predicted can be found at:

Is amplifying the "Receiver Amplifier" Value ? Is threshold the "Minimum Threshold" value? Yes Why would you want to create overlapping submaps? In our situation we had two isles of glass in a L shape. L shape.jpg The beacons on one far end couldn't hear beacons on the other far end in a straight l...
