Hi everyone, I’m working on an underwater vehicle project using a Pixhawk running ArduSub firmware. I’m communicating with the Pixhawk via pymavlink and reading the heading value from the VFR_HUD message to keep the vehicle going straight with a simple PID controller. The main problem is that even…

Hi @beyza - If you’re not happy with the output of the EKF, you could try calibrating your motion sensors again, particularly the compass and the Gyro, from within BlueOS ( Vehicle Setup .) However, I would not expect better than +/-1 degree with a well calibrated system, after all these are low-cos…

Hi Tonny, thank you for your detailed explanation and the information you shared.
