Help with AHRS failure in PreflightCheck

PX4 Autopilot
1

Hi, I am currently experiencing an issue with my PX4 system where the AHRS failure message appears, even though I have a 3D fix from the GPS. The system seems to be unable to arm the drone, and I’m not sure what could be causing this issue.

What I need help with:

  • Are there any specific settings or logs I should check that could give me more insight into why the AHRS system is failing despite having a solid 3D fix?
  • Could the problem be related to a specific parameter or sensor?
  • Any advice on troubleshooting AHRS issues in PX4 would be greatly appreciated!

Thanks in advance for any assistance!

Yeah

  1. just because you have GPS lock doesnt mean everything is good to go. AHRS encompasses the position of the drone. so the IMU as well. Infact I think it is the IMU that is the issue here
  2. make sure you calibrate all your sensors and are running the most recent version of PX4
  3. Turn on logging so that it starts on power up and stops on shutdown SDLOG_MODE
  4. Post the log here so we can take a look

Thanks for your reply!

  1. I’ve already calibrated all the sensors, including the IMU, and made sure everything is set up correctly.
  2. I’ve also updated to the latest PX4 firmware version.

Here’s the log file for you to take a look at: [Log file link]
