Understanding IMU messages

As in an overview of all messages, What is the difference between SCALED_IMU, SCALED_IMU2, and SCALED_IMU3 in PX4?

Thanks you in advance for all kind of help :slight_smile:

Hi,

As stated below the message title


SCALED_IMU
The RAW IMU readings for the usual 9DOF sensor setup. This message should contain the scaled values to the described units

SCALED_IMU2
The RAW IMU readings for secondary 9DOF sensor setup. This message should contain the scaled values to the described units

SCALED_IMU3
The RAW IMU readings for 3rd 9DOF sensor setup. This message should contain the scaled values to the described units

I.e. they are the sensor values from the different IMU:s on board
