In addition to the above delivered parts, the following is needed:
•
GPS antenna cables and the cable between the Processing Unit and the MRU junction
box.
•
A 19-inch rack for mounting of the Processing Unit.
•
Gyro compass data on a serial line (recommended).
•
DGPS corrections on one or more serial lines for improved position accuracy
(recommended).
•
Additional cables for input of Gyro compass data and DGPS corrections, and for output
lines to external equipment.
•
Devices for reference measurements of roll, pitch and heading (for calibration).
•
An external IBM-compatible PC with MS-Windows for setup and calibration.
General arrangement drawings of the ship should be acquired to simplify determination of
offsets between the GPS antennas, the MRU and the ship's centre of gravity (CG). 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.
For external interfaces, electrical characteristics and data formats must be decided, and the
necessary cables and connectors made available. Power supply for the Processing Unit and an
external computer for setup and calibration are also needed.
An external heading reference, for example a surveyed quay is required for heading
calibration. For some applications, pitch and roll reference for calibration is also needed.
The MRU unit is shipped in a specially designed transportation container. Keep the MRU
within the container until everything is ready for installing the unit in the mounting bracket.
Note
After the installation, please save the transportation container. The MRU must be
shipped in this container for service or repair to maintain the warranty.
3.2 Logistics
Safety:
General safety guidelines to be followed when working in mast and on deck.
Personnel qualifications:
Trained electrical workers.
Minimum number of personnel:
2, especially when mounting the Antenna Bracket to the Holder.
Ship location:
The GPS antennas have to be mounted such that blocking of the GPS signal is
avoided. The MRU 5 unit is preferably mounted low in the ship or close to the system to be
compensated. The Processing Unit can be mounted on the bridge or in the instrument room.
Special tools required:
A PC with Microsoft Windows 95, 98, NT version 4.0 or compatible.
