Mounting GNSS Compass
Mounting Location
When installing GNSS Compass into a vehicle, the mounting position and alignment of the unit are essential for achieving optimal performance. Position refers to the physical location within the vehicle where the unit is installed while alignment refers to the orientation of the unit with respect to the orientation of the vehicle.
When planning a mounting location for GNSS Compass, refer to Mounting Location example, and be mindful of the following recommendations.
-
Mount the unit in clear view of the sky
-
Mounting the unit at least 3m from transmitting devices, otherwise they may degrade heading performance due to interference.
-
Mount the unit in an area that will not exceed the rated temperature range, and with minimal temperature fluctuations.
-
Mount the unit away from high levels of vibration where possible.
-
Mount the unit at least 10 cm away (and preferably as far as possible) from sources of dynamic magnetic interference such as high current wiring or large motors for best performance.
Mounting Options
The GNSS Compass can either be pole mounted, or surface mounted. See Mechanical Drawings for details
Pole mounting
If pole mounting the unit, connection is via a single 1-14 UNS-2A thread. The provided 1" nylon and 1" locking nut should be used to mount to a suitable mounting pole as illustrated in Pole mounting assembly (pole mount not included).
Surface mounting
If mounting on a surface, use the 4 x M8 fixing holes as indicated in the Mechanical Drawings. It is strongly recommended to use the included shoulder washers to provide a small gap between the GNSS Compass and the mounting surface. This will help protect against warping or cracking of the unit on slightly uneven surfaces. Note the shoulder washers will require a nominal 10mm hole in the mounting surface as shown in Surface mounting shoulder washer.
