"Hi Thomas, Are you referring to Cedi's post or my question? If mine, I was not able to find the PCB image for Pixhawk 3 either. Does the contents of this link give the required…"

"Hey Cedi, The MPU9250 (an obsolete component) uses the AK8963 Hall effect sensor and the MPU6500 gyro/accel. The LIS3MDL is a magneresistive sensor, so I would expect the output of the two LIS3MDLs to have similar quality of their plots.. The…"

"Hi Armin, Thank you very much for the suggestion. I am using that to check if sensor_mag values are provided individually.But I am only able to find the fused magnetometer value.It shows up in the second pic as "M1:HIGHRES_IMU.xmag"…"

"Oh sorry my mistake. In QGC under the menu Wigets is the Analyze. Use that tool to plot in real-time that data. My suggestion is to connect the Pixhawk directly via USB to your computer. The data update vie your telemetry link is slow and might not…"

"Hi Armin, The plots that you see in the beginning is not my case. That was the case from the original poster, Cedi. My question is how to get those plots so that I can investigate my case further."

"Same direction, but it looks your external sensor is upside down. I would for testing the external  or both internal sensors rotate 180deg around the x-axis."

"Hi Armin, Thanks for the insight. Actually, I have set the system such that vehicle and the external compass points in the same direction. Before calibration of the compass in PX4 firmware, I have set the orientation of auto-pilot and the external…"

"To me it looks you didn't set the orientation (s) proper of the magnetic sensors."

"Hi @Cedi, Did you figure out your issue? I am also facing a similar problem. But first, may I know how did you plot up those sensor_mag values? Is there a parameter to enable to visualize the mag values separately? Regards,"

Problem with internal magnetic sensors PIXHAWK 3 PRO

Firmware v1.7.3 & QGC v3.3.0 During test flights I noticed that the drone does not fly the route I specified, but always flies in any other direction. Several times I recalibrated all sensor systems with QGroundControl and still got the following warining: preflight failed mag sensors inconsistentAfter a few searches, I found the cause: One internal magnetic sensor provided data that differed greatly from the other internal magnetic sensor and the magnetic sensor of the external…See More
