IMU Orientation

Align the IMU of the device to obtain the correct measurements, as shown below:

Place the device into the vehicle so that the IMU chip inside is aligned with the axis,

Ensure that the device is placed in a manner that does not disturb the orientation of the IMU axis.
Or ensure the device's orientation is not disturbed for more than one axis when installing or operating.

In case of misalignment, align the 'Z' axis first, followed by 'Y' and then 'X'. The chart below explains the attributes of all three axes in detail:

To Calculate the exact angle in case of misalignment:

Keeping the actual position of the axis in mind- measure the angle of misalignment.
Subtract the current measured angle from the actual angle value.

For example, if the vehicle's attitude is misaligned at its roll, the axes Z and Y are misaligned.

<MountYaw>0</MountYaw>
<MountPitch>0</MountPitch>
<MountRoll>45</MountRoll>

Similarly, if the vehicle's attitude is misaligned at its yaw, the axes X and Y are misaligned.

<MountYaw>315</MountYaw>
<MountPitch>0</MountPitch>
<MountRoll>0</MountRoll>

Similarly, if the vehicle's attitude is misaligned at its pitch, the axes Z and X are misaligned.

<MountYaw>0</MountYaw>
<MountPitch>-45</MountPitch>
<MountRoll>0</MountRoll>
