EKF, BAD barometer and compass covariance

My drone just continues to report these errors. When I first boot raspi, there is no error. However, after several rotations in my hand or a few seconds’ take-off and landing operation, these error occurs. And there is always no 3D fix even I am under open sky.

Does anyone have any idea how to solve this? I barely can fly it because of these errors.

Hi Jason,

I would start from:

  • Fix your Navio2 will all 4 screws, I can see from pictures that at least 1 is missing
  • Shield RPi camera as it causes interference with GPS, there are many topic on this form on how to do it.

Thanks. I will try those
