Installation Parameters
Once the POS MV components are installed, the installation parameters must
be measured. These measurements allow the POS MV to deliver the best
possible performance.
After you have configured the system with these parameters, save the data to
non-volatile memory for immediate use each time the POS MV is powered-on.
The POS MV configuration information defines the layout of the system and
its associated peripheral equipment relative to a reference point. The
reference point is defined as any convenient location on the survey vessel,
and it may be assigned any orientation that you choose. Once you have
decided on a reference point, make the following measurements as carefully
and accurately as possible.
Lever Arm Distances
Note: Measure distances in metres, resolved into their longitudinal, lateral
and vertical components in the reference frame.
• Reference to IMU - measure to an accuracy of ±0.05 m (~±2 in)
