Guys. Help solve the problem. Very often a compass error began to appear. Then the error disappears and the drone begins to drift by 1m to the side. After a reboot, the problem disappears, but it often appears again. How to fix it?

Are you flying nearing any ferrous materials or frequency emitters, i.e. bridges, metal fences, radio towers, powerlines? These are common in causing compass errors.

Have you done an IMU recalibration?

Hello and good day Jackson_87. I am sorry to know that you are having this issue with your DJI Mavic Air. May I know if the drone's firmware is on it's most recent one and can you please try to calibrate the IMU of the said drone to check if after this process the issue will still persist. I will be posting and official DJI Tutorial Video on how to properly calibrate the IMU of the DJI Mavic Air. In addition while flying your drone please keep distance to any possible interference like the metal object or radio frequency. Please keep us posted on the said issue for us to help you further. Thank you.

Not. I did not fly there. What else could be the reason?

Hey. The latest firmware version is installed. Tomorrow I will do the calibration of all the sensors. I will take your advice and give feedback.

Hmm... if theres no metal or radio waves, then a sensor might have failed. I think you would need to send in repairs

I will try to solve the problem myself. If I fail, then I will send the drone for repair.

I solved my problem. the problem was in the magnetization of the compass. I demagnetized the compass with a special device and the error disappeared. Thanks for the advice. special device - cfixer

Hi jackson, what special device would that be? having similar problems not being able to calibrate compass ... and if it does calibrate, the flight does not take longer than 60 seconds (shaky) before a message appears in the app on the compass needing calibration ..
Thanks!
