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,

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.

Configure/edit in Xml

<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.

Configure/edit in Xml

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

Influx devices combine the Global Navigation Satellite System (GNSS) and dead reckoning for optimal navigation and location accuracy. While GNSS provides precise positioning under ideal conditions, its signal can be weakened or lost in certain environments, such as tunnels, urban canyons, or dense forests, and this is where dead reckoning steps in.

Using an accurately aligned IMU configuration, these devices help detect and plot navigation routes and patterns in areas with minimum GNSS coverage, such as tunnels, underground parking, subways, or other such areas.

Dead reckoning continuously estimates your position based on your device's movement data, such as speed and direction. When GNSS signals are unavailable, dead reckoning takes over, ensuring uninterrupted navigation until the GNSS connection is restored.
