F180R MOTION Sensor User and Reference Guide
NOTE: The F180R System comes with a standard set of 15m (Novatel CO16) antenna
cables with options for 5m (Novatel C006) and 30m (Novatel C031). Refer to Appendix
- Antenna Cable for further technical information on antenna cables.
the optional antenna mounting bar (supplied on request)
a kit of suitable tools
waterproof sealing tape or compound
cable clips
To install the antennas:
1. Choose a location for the antennas using the guidelines printed above.
NOTE: It is essential that you check and record the separation distance between
the two GPS antenna centres before you finally mount the antenna assembly,
otherwise it might be difficult to obtain an accurate measurement. It is essential
that you measure this antenna separation to an accuracy of better than 5mm. This
measurement will be used as the Antenna Separation input parameter in the
MOTION Control application. Once you have done this, the system will use
measurements delivered by the dual GPS receivers to 'aid' the independent
measurements of the IMU.
For simplicity and convenience, you may make this measurement as soon as you
have mounted the two GPS antennas on their mounting bar. For accurate
measurement make sure you measure at the Antenna Reference Points.

2. Fix the optional mounting bar or your antenna support in position using bolts at both
ends to ensure rigidity of antenna installation. The bolt dimension is 5/8 inch by 2
inches, UNC stainless steel.
3. Decide which end of the mounting bar will support the primary GPS antenna and which
end will support the secondary GPS antenna.
