where possible.
6. For best performance during GNSS outages, Spatial Dual should be mounted at
least 10cm away from sources of dynamic magnetic interference i.e. high
current wiring, large motors.

Alignment

The easiest way to align Spatial Dual 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.
If aligning Spatial Dual with the vehicle axes is not possible or not optimal, it may be
mounted in a different alignment and the alignment offset should be configured using
Spatial Dual Manager, see section 11.8.5. For easy alignment, the set zero orientation
button in the Spatial Dual Manager alignment dialogue can be used to set the current
orientation as the level alignment, see section 11.8.5. Please note that this will only
correct for roll and pitch offsets. Any heading offset will need to be entered manually
and saved after using this function.

Mounting Plate

Spatial Dual's mounting plate and hole guide is shown below in Illustration 15. The
holes are designed for M3 cap screws.

Power Supply

A high level of power supply filtering has been built into Spatial Dual, however it is still
recommended that the power supply be free of significant noise. Spatial Dual contains
a fully isolated power supply and has separate grounds for power and signal to ensure
that power supply noise does not corrupt communications or cause ground loops with
