Noisy output

[manbehindthemadness]

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.

After inspecting the numbers this seems to only relate to the tilt compensated heading value, the gyro values are spot on.

I am using that exact filter; however, I’m getting around +-8 degrees in the noise

are you looking at the heading value? have you calibrated your compass and confirmed this by graphing out the results?
