Alignment; Mounting Plate - Advanced Navigation Spatial FOG Dual Reference Manual

6. As FOG technology is subject to minor bias variations under strong magnetic
fields, Spatial FOG Dual should be mounted at least 0.25 metres away from
sources of dynamic magnetic interference such as high current wiring, large
motors and rotating or reciprocating machinery.

Alignment

The easiest way to align Spatial FOG 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 FOG 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 the alignment configuration dialogue in Spatial FOG Manager, see section
11.8.4. For easy alignment, the set zero orientation button in the Spatial FOG Manager
alignment dialogue can be used to set the current orientation as the zero orientation
alignment, see section 11.8.4. Please note that this will only correct for roll and pitch
offsets. Any heading offset will need to be entered manually and saved before using
this function.

Mounting Plate

Spatial FOG Dual's mounting plate and hole guide is shown below in Illustration 16.
The holes are designed for M4 bolts. The alignment holes can be used to ensure
precise alignment of Spatial FOG Dual through the use of alignment pins.
