This equipment uses GPS satellite signals to determine the bearing of the ship. Install the sensor where there are no impediments to electrical signal reception, and no signal reflection. If the sensor installation location environment is unsatisfactory, ship bearing calculations is repeatedly interrupted. If selection of the optimal installation location is difficult, and some concessions must be made, place the sensor in the desired installation location and test the acceptability of the sensor results before permanently installing the sensor. Installing the sensor in an inappropriate location may result in decreased accuracy and equipment failure. Whenever possible, select a place having the following characteristics.

Out of the mast's shadow. (2 m or more separation)

2 m or more outside of any radar beams. Installation near radar antennas may result in multipath wave interference, which decreases the accuracy of the equipment. Whenever possible, keep the equipment out of any beams.

Away from the Inmarsat antenna by at least 5 m, and out of the scope of the beam.

An open space which allows uniform reception of satellite signals.

Section 1 Equipment Overview

1.1 Functions

This equipment determines the heading of a ship by measuring the orientation between two antennas using the signal from GPS satellites. The equipment not only determines the heading with high accuracy anywhere in the world and in all weather conditions using the GPS satellites, but determines the position, course, and speed of the ship. When the DGPS beacon receiver is connected, the accuracy of position fixing can be enhanced by receiving correction data from the DGPS beacon station. Since this equipment outputs the bearing information at high speed, if the unit is interfaced to a JRC radar unit, it is possible to fully draw the capabilities of the radar and ARPA.

1.2 Features

●

High accuracy and high stability (0.5 rms degree)

●

Short setting time (less than 2 minutes at warm start fix)

● H

igh speed tracking response (Tracking rate of turn is 45 degree/sec)

● High visibility

5.7-inch FSTN LCD

●

Many utility display modes (Compass rose graphics, ROT, NAV, GPS status, etc.)

● Easy installation

●

Direct connection to the JRC radars

・

Be careful not to damage the equipment during loading or installation.

・

Do not lift the sensor by the equipment cabling.

It is recommended that the sensor be installed midway on a strong pole or mast. In order to minimize vibration and improve maintainability, the sensor should not be mounted at an excessive height.

Use a sufficiently thick metal base for the sensor mount, and any necessary additional reinforcing materials, to reduce vibration and shock as much as possible. Use stays or wires on the pole or mast on which the mount is connected in order to further reduce vibration or shock to the sensor. Ensure that the mounting surface is as flat as possible. Do not use rubber, resin, or other flexible materials in order to flatten the mounting surface, as this may result in reduced resonance frequency and increased vibration. It may also cause mounting bolt loosening of the material when degraded.

Use appropriate bolts for the sensor, and tighten all bolts equally. The length of the mounting bolts varys based on the thickness of the mount, but select bolts of such length that the amount extending past the nut is twice the thickness of the nut. Some initial loosening may occur after tightening. Perform a second bolt tightening some time after the initial tightening. After installation, check the tightness of the installation bolts periodically. It is especially important to check the bolt tightness after traveling in inclement weather, regardless of how much time has passed since the last check. Continued use of the same bolts may result in decreased strength, bolt degradation, or bolt breakage. If this occurs, replace both the bolt and the nut with a new bolt and nut. If bolt loosening occurs frequently, please consult with a JRC technician.

Install the sensor as horizontally to the ship as possible. If it is tilted largely, direction accuracy may be degraded.

Attention

● Cable Connection Procedure

The unit shown in the figure is the NNN-20, which is almost identical to the NNN-30.

1. Install clamp filters (one large and one small) to the antenna side of the included cable. Roll the cable once around the large clamp filter. Also install a clamp filter (small) to the display side. (Refer to the following figures.)

NOTE1: Determine the installation position of the clamp filter (large) by considering the

installation condition of the sensor. (Refer to the installation figure on page 2-7.)

2. Processing Clamp Filter

2.1 Roll up a self bonding tape around the clamp filters in the antenna side. (No need to roll up the one in the display side.)

Roll up the tape by pulling so that the tape will be lengthened by two times. Also, roll up

the tape so that the half of it is overlapped. Repeat three times to make it three-layered.

After rolling up, press the tape with the fingers for secure attachment.

2.2 Wrap by a vinyl tape for protection.

Do not put tensile force to the vinyl tape as much as possible. Roll up the vinyl tape so that

the half of it is overlapped. Repeat three times to make it three-layered.

Crimp the end of the rolled tape without tension. Press the whole tape with the fingers for

secure attachment

● Installation Procedure

The unit shown in the figure is the NNN-20, which is almost identical to the NNN-30.

1. Provide a mounting plate as shown below, and secure the sensor unit. Use M10 hex bolts, washers, spring washers, and nuts to secure it. Tighten the bolt by 3430 N-cm of torque (350 kg-cm). When making holes in the mounting plate, beware of bow direction. Excessively long bolts may reach the sensor unit. For 5 mm (1/5 inch) mounting plate, M10 x 30 mm bolts are just fit. Using double nuts is also effective to fix plate permanently.

2. Use RTV rubber to cover the hex bolts and nuts.

3. Fix the clamp filter (large) to the installation pole by using a bundling band (long). Fasten both ends of the large clamp filter. Fix it as closer to the antenna as possible. If it is impossible to fix to the pole, make holes in the mounting plate for bundling bands to go through, and fix the clamp filter to the mounting plate.

4. Cramp at the preferable position so that the cable weight itself will not be applied to the connector. If some slack is provided for the cable, beware of the influence from wind or sea wave. Arrange the cable so that it will not be hooked by a crane or fishing equipment.
