Can anyone explain the working principle of external IMU? Or provide relevant research information, because I am a newbie and have not been able to find more critical relevant information.
There are mainly the following issues:
According to the setting instructions on the ardupilot official website (External AHRS Systems ā Copter documentation)
There is no mention of turning off the internal IMU. Why is there no need to turn off the internal IMU? Is it because the flight control will force the use of an external IMU? Or will it integrate external and internal data?
Thanks for the advice
