[Question] What is the expected orientation by the sensor fusion algorithm?

[cparata]

Hello,
I'm trying this great sensor fusion algorithm. I would like to know what is the expected orientation of the sensor data as input of the sensor fusion algorithm. Is it E-N-U or N-E-D? What is the output orientation?
Thanks in advance for the clarification.
Best Regards,
Carlo

The README states, "The quaternion describes the orientation of the sensor relative to the Earth using the North-West-Up (NWU) convention."

Ok, thanks. So, I guess that also the input of the sensors are expected with the same convention, correct?

ENU, NED, and NWU are conventions that describe the Earth axis directions. For example, ENU means X = East, Y = North, and Z = Up. Such conventions have no meaning applied to the sensors because the sensors move relative to the Earth.

Ok, thanks.
I close this issue.
