POS MV V5 Installation and Operation Guide
Installation
2-4
Inertial Measurement Unit
The IMU has anodized aluminium housing. If you intend to mount the IMU against a steel hull, use
stainless steel spacers of 5 mm (
3
/
16
in) thickness between the IMU and the hull to prevent galvanic
corrosion of the housing. Applanix recommends the use of an IMU mounting plate to aid in aligning the
IMU with the vessel reference frame in which lever arms and misalignments are measured. Refer to
Applanix for details.
Follow the installation instructions listed on page 2-7, Inertial Measurement Unit, to select a suitable
mounting location for the IMU. Observe the environmental limits starting on page 7-5 when selecting a
mounting location for the IMU. Although the IMU is sealed in a housing it is not depth-rated; do not mount
the IMU where it can become immersed in water. An IP68 rated (submersible) option is available, details
of which are available from Applanix Customer Support (see page Appendix A for contact details).
POS Computer System
Applanix ships the PCS in a protective transit case that must be removed prior to operation. Please retain
this packing case for reuse should the system need to be shipped for any reason. Follow the instructions
in the installation paragraphs, starting on page 2-9 for V5 and page 2-13 for V5-1 and V5-2, to install the
PCS. Observe the environmental limits starting on page 7-5 when installing the PCS.
