  • Page 13: Section 1 Equipment Overview

    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.

  • Page 20: Sensor Installation

    SENSOR INSTALLATION CAUTION Do not bend the cables included with this equipment excessively, or twist them or subject them to other strong forces. Doing so may result in damage to the interior or exterior of the cables, and may result in fire or electrocution. Do not install the equipment in places subject to vibration or shock.
  • Page 21 Attention 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.
  • Page 22 ● 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.
  • Page 23 3. Connect the included cable to the sensor unit. Tighten the nut firmly in order to waterproof the connector (a click sounds when plugged in firmly). After connecting, apply RTV rubber on the connector for additional waterproofing. Waterproofing 3. With using the included bundling band (short), clamp the cable as shown below. Position should be between GPS1 and GPS2.
  • Page 24 ● Installation Procedure The unit shown in the figure is the NNN-20, which is almost identical to the NNN-30. 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).
  • Page 25 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.
  • Page 26 ● Installation Procedure for Optional Mount Base for NNN-20 1. Install the mounting base to the pole by using fixing brackets, M8 bolts, flat washers, spring washers, and nuts. Then, secure the sensor to the mounting base. Beware of the bow direction.
  • Page 27 2. Fix both ends of the clamp filter (large) by using bundling bands (long) to secure the cable. Let the bands go through the holes of the mounting base. GPS1 GPS2 GPS3 Contact the pole end to Fix by bundling the mounting base.
