AHRS Calibration level

Hi, I tried to calibration the Navio card without being able to get it. when I place the card over the ground, pitch and roll, it vary, when it should stay at 0 degrees. could you tell me how to perform a more accurate calibration of level for AHRS. We are trying to develop a new controller based on the structure and we need precision in sensors.

Hello there!

Could you please what exactly are doing? What Raspberry Pi are you using? What Navio do you have? What GCS? How is everything connected (Radio, UDP, TCP)? Sorry, I’m also a little bit confused by your phrasing about calibration. So you’ll need to elaborate!
