Re: Firmware and Params for autonomous flight (Link to firmware added)

@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...

Re: Firmware and Params for autonomous flight (Link to firmware added)

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.

Re: Firmware and Params for autonomous flight (Link to firmware added)

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)

Re: Firmware and Params for autonomous flight (Link to firmware added)

@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...

Re: Firmware and Params for autonomous flight (Link to firmware added)

@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.

Re: Firmware and Params for autonomous flight (Link to firmware added)

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...
