Installation

9.1

Installation Checklist

1. Securely mount the unit to the vehicle following the guidelines in section 9.2.
2. Mount the two GNSS antennas following the guidelines in section 9.5 and then
connect the antenna cables between the antennas and the Spatial Dual unit. If
the two antennas are not installed in the standard configuration of primary front
and secondary rear, the offset will need to be entered into the Dual Antenna
dialogue in Spatial Dual Manager.
3. Connect the connector cable to Spatial Dual and then connect a suitable power
supply as specified in section 9.4. A suitable power supply is included in the
evaluation kit.
4. Connect the USB converter cable to the primary port and a computer, open the
Spatial Dual Manager software and click connect.
5. If the unit is mounted in an alignment other than the standard alignment of X
pointing forward and Z pointing down, this alignment offset will need to be
entered into the Alignment Configuration dialogue in Spatial Dual Manager.
Please see section 9.2.1 for more details.
6. Accurately measure the primary GNSS antenna offset from the centre of the
Spatial Dual unit to the central base of the antenna in the body co-ordinate
frame (X positive forward and Z positive down) and enter these values into the
Alignment Configuration dialogue in Spatial Dual Manager. Please see section
9.5 for more details. Please note that the body axes are always X positive
forward and Z positive down irrespective of any alignment offset entered in the
previous step.
7. Enter the vehicle type in the Filter Options dialogue in Spatial Dual Manager.
8. The system is now ready for use.

Position and Alignment

When installing Spatial Dual 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 Dual should be mounted in an area that is not going to exceed it's
temperature range.
2. Spatial Dual should be mounted away from high levels of vibration where
possible.
3. Spatial Dual should be mounted within several metres of the GNSS antennas
where possible.
4. If atmospheric altitude is going to be used, the two vents on the sides of Spatial
Dual should not be obstructed.
5. Spatial Dual should be mounted close to the centre of gravity of the vehicle
