Installation
This section contains the information necessary to install, power up and initialise the system
ready to start surveying.
7.1
Pod installation
The Dynascan pod should be mounted securely using four bolts passing through the holes of
the pod mounting bracket. The pod must be mounted clear of any metal obstructions close
to and above the GNSS antennas, which may cause multipath effects.
N.B. It is important for the pod to be mounted on a flat surface and that no distortion of the
pod base takes place when the bolts are tightened. If distortion of the base plate occurs it
will affect the calibration of the pitch and roll values.
When the system is vehicle mounted a roof rack and ladder can be used to provide a
reasonably rigid, cost effective, platform on which to mount the Dynascan pod and
secondary GNSS antenna. This has the added advantage of not having to re-calibrate the
heading if the same fixing holes are used for the pod and GNSS antenna. It is recommended
that a flat metal base plate be fixed to the ladder, which will provide an even flat surface for
the Dynascan pod. The pod should be fixed so that the laser beam clears the back of the
vehicle, including any tow ball.
When using a second GNSS antenna, for heading, the pod and antenna should both be
mounted along the centreline of the vehicle with the antennas at the same height. The
distance between the antennas should be ideally 1.0 to 1.5 metres (do not exceed 2 metres).
Examples of vehicle and vessel mounting are shown below.
