I am experiencing pretty noisy IMU readings, is there way to adjust the kalman filter (from your GitHub example) to produce a smoother output. I need to get it down to a +-2.5 degree variation as my platform triggers a course correct after 5 degrees of drift.

August 28, 2020 at 2:35 pm #16194Mark WilliamsKeymasterare you looking at the heading value? have you calibrated your compass and confirmed this by graphing out the results?
