Position and Alignment

When installing Spatial into a vehicle, correct positioning and alignment are essential to achieve
good performance. There are a number of goals in selecting a mounting site in your application,
these are:
1. Spatial should be mounted close to the centre of gravity of the vehicle.
2. Spatial should be mounted as far from sources of dynamic magnetic interference as
possible i.e. high current wiring, large motors.
3. Spatial should be mounted within several metres of the GNSS antenna where possible.
4. Spatial should be mounted away from vibration where possible.
5. Spatial should be mounted in an area that is not going to exceed it's temperature range.
6. The two vents on the sides of Spatial must not be obstructed.
6.1.1

Alignment

The easiest way to align Spatial is by installing it with the sensor axes aligned with the vehicle
axes. This means that the X axis points forward towards the front of the vehicle and the Z axis
points down towards the ground. Examples of this are shown below in Illustration 24, Illustration 25
and Illustration 26.
If aligning Spatial with the vehicle axes is not possible or not optimal, it may be mounted in a
different alignment and the alignment offset must be configured using either the Spatial Manager
software or the Installation Alignment Packet. For precise alignment, the Set Zero Orientation
Alignment Packet can be used to set the current orientation as the zero orientation alignment.
For more information on setting the alignment please see the Spatial Manager software manual or
the alignment packet in section 9.9.5.
