ArduPilot
Sub: EKF3 IMU0/1 forced reset
Bug report
Please describe the problem
The heading angle output from my EKF3 always gets reset and cleared to zero. I've checked the logs and still can't see the problem. Can anyone please help me? My work log is as follows.
Some people have analyzed that it may be a problem with the accelerometer and needs to be recalibrated, but I feel that my accelerometer data is correct.

Hi @CasADi-acados,
Thanks for the report. Support issues really should go into the support forums but I'll leave it here because we don't do much sub support on the AP discord servers. That's normally handled by BlueRobotics but I see in this case that you're not using the BlueRobotics hardware (which is a-ok of course).
Any chance you could use a more modern version of AP? 4.1 is quite old.

Thank you very much for your reply. I currently think it is a problem with the EKF3 filter algorithm. I don't know which data abnormality caused its forced clearing.

Is there a newer version of ArduSub? I haven't found it yet.

May I ask, are these the latest ones?

I think it's a problem with EKF3. I don't know why there are burrs in the curves of my two graphs. I feel like my acceleration curves are quite normal.
