Are brushless motors and GPS susceptible to magnetic interference?

Hello.
Switching to “Loiter mode” in the helicopter will cause toilet bowling.
I have checked the log data and cannot tell if it is affected by magnetic interference.

Please help by checking the log data.

Best regards.

Yes, brushless motors produce a lot of electro-magnetic interference.

magnetometers are very sensitive and will see this interference and get confused by it.
Sometimes GPS Receivers also get this interference.

Keep the above sensors away from high current wires!

Thank you for your response.
Looking at the data, what specific numbers would allow you to determine that you are not affected?

Best regards.
