3.2 Mounting plate
The mounting plate is designed to be permanently or semi-permanently fixed to the site superstructure. The FiX1
can then be easily attached once the mounting plate is in place. The FiX1 can also be easily detached from the
mounting plate, if required for site operations or for servicing.
The centre of the mounting plate is marked with an etched cross. To ensure that all FiX1 data is correctly
georeferenced, use traditional survey techniques to survey in the FiX1 reference point on the local site coordinate
system.
The long axis of the etched cross provides a reference line to indicate the heading of the FiX1. Use traditional survey
techniques to survey in the FiX1 reference line on the local site coordinate system.
Twelve holes – for size M8 bolts – are positioned in a circle, at 30° intervals. These provide options for attaching
the mounting plate to the site superstructure.
Four threaded holes – also size M8 – are positioned with two at either end of the mounting plate. These line up with
holes in the FiX1 baseplate and are used to directly attach the FiX1 unit to the mounting plate.
Two guide pins ensure that the FiX1 can be held in place while the unit is screwed onto the mounting plate.
See section 5 for details on installing the mounting plate, surveying the system into a site coordinate system, and
attaching the FiX1 unit to the mounting plate.
