Figure 1 Standard system for 19-inch rack mounting
In addition to the above delivered parts, the following is needed:
A 19-inch rack for mounting of the Processing Unit.
A 19-inch rack for mounting of the HMI Unit.
GNSS antenna cables and the cable between the Processing Unit and the MRU
junction box.
DGPS/DGLONASS corrections on one or more serial lines for improved position
accuracy (recommended).
Additional cables for input of DGPS/DGLONASS corrections, and for output lines
to external equipment.
Devices for reference measurements of roll, pitch and heading (for calibration).
General arrangement drawings of the ship should be acquired to simplify determination
of offsets between the GNSS antennas, the MRU, the Navigation Reference Point
(NRP) and the different monitoring points. Locations for the various parts of the system
must be decided and mounting arrangement for the Antenna Bracket and sufficient
lengths of cable made available.
An external heading reference, for example a surveyed quay, is required for heading
calibration. Survey equipment should be made available for determination of the
alignment offset in roll, pitch and yaw.
