1 PRINCIPLE OF OPERATION Own ship's heading can be determined by decoding the data in the carrier frequency in addition to ordinary GPS parameters. In principle, a pair of two antennas A1(ref) and A2(fore), each connected with an associated GPS engine and processor, are installed along the ship's fore-and-aft line. GPS systems at A1 and A2 calculate the range and azimuth to the satellite. Difference in range between A1 and A2 is ∆λ + nλ where λ is 19 cm.

2 INSTALLATION 2.1 Mounting Considerations 2.1.1 SC-series antenna unit General • Keep the length of antenna cable in mind when selecting a mounting location. The cable comes in lengths of 15 meters (standard supply), or 30 m or 50 m (optional lengths). • Select a location where vibration and shock are minimal. Installing the antenna above superstructures The antenna must be mounted above all other structures on the vessel to obtain an unobstructed view of the satellites regardless of vessel heading.
2. INSTALLATION • The horizontal separation between the antenna and masts must be as follows: Mast diameter 10 cm 30 cm Separation distance (minimum) 1.5 m 3m -80° +80° Separation degrees • Keep the length of antenna cable in mind when selecting a mounting location. The cable comes in lengths of 15 meters (standard supply), or 30 m or 50 m (optional lengths). • The field of view above the antenna should be as shown below, ±80° against zenith.
• Locate the antenna above the radar antenna, out of the radar beam. Sc-series Antenna Radar Antenna Example of improper installation Location influenced by reflected wave. NO! UNSUITABLE LOCATION SC-series Antenna SC-series antenna located below all other structures Radar Antenna Reception blocked by mast. Bridge Example of improper installation 2.1.2 Display unit, processor unit • • • • Choose a location where vibration and shock are minimal.

2. INSTALLATION 2. Fix the antenna unit to the post as shown below. 3 1 2 Set the antenna unit to the flange. Fix the antennas #1 and #2 on the fore-and-aft line of the ship, with the #2 a ntenna forward of the #1. Flat washer Spring washer Nut (Torque: 29.58 Nm) Fastening antenna unit to a post 3. Coat each nut, bolt and washer with silicone rubber for waterproofing. Coat bolt, nut and washer completely with silicone rubber.
2. INSTALLATION 4. As shown below, make a loop in the antenna cable and fasten the antenna cable to the antenna post with two cable ties. Coat bolt threads with Three Bond. Fasten bolt with nuts and then coat nuts with Three Bond also. Coat with Three Bond 1211 (supplied). Fix antenna cable. 5. Coat bolt threads with Three Bond 1211. Fasten bolts with nuts. Coat nuts at the bottom of each antenna element with Three Bond 1211. 6. Paint post and support plate with anti-corrosive paint. 7.
2. INSTALLATION DGPS antenna unit Choose a mounting location for the DGPS antenna considering the points mentioned below. DPGS is not necessary for heading determination, however it can improve the accuracy of GPS position fixing • Separate the DGPS antenna at least three meters from a radio antenna. • Do not install the DGPS antenna within the radar beam. 1. Mount the DGPS antenna by one of the methods below. • Screw it into a one-inch threaded pipe.
2. INSTALLATION 4. The DGPS antenna is supplied with a 15 m cable. If extension is necessary use the extension cable (option). Cover the extension connectors with vulcanizing tape and vinyl tape, for waterproofing. Tie tape ends with a cable tie. Extension Cable: Type: OP08-15-30, Code No.: 004-396-440 (30 m) Type: OP08-15-60, Code No.: 004-396-450 (60 m) Name Connector Cable Type TNC-SA-JJ TNC-PS-3D L30M Code No.
2. INSTALLATION 2.3 Installing the Processor Unit The processor unit should be mounted aligned with the ship’s fore-and-aft line. It can be mounted on the deck, bulkhead, or on the underside of a desk. Choose a mounting location which allows you to easily view the power lamp on the top of the unit and which is within ±2.5° of the ship’s fore-and-aft line. 2.3.1 Deck mount 1. The processor unit is factory adjusted for deck mounting.
2. INSTALLATION 2.3.2 Bulkhead mount For mounting on a bulkhead, use the bulkhead mounting plate supplied with the installation materials. 1. Unfasten four screws from the top cover to open the front panel. 2. Unfasten two screws to dismount the angular rate sensor. Angular Rate Sensor BEACON 20P8171 Processor unit, top view 3.

APPENDIX HDM- Heading – magnetic This sentence is not used in the current version of NMEA and IEC 61162. Some boaters may want the GPS compass to indicate the magnetic heading when the boat is only fitted with a magnetic compass. HDG is calculated by adding a geomagnetic variation to HDT. $--HDM, x.x, M *hh Heading, degrees true HDT - Heading - true True heading in degrees obtained by processing RF cycle in the GPS carrier frequency. $--HDT, x.

APPENDIX Parts List This equipment contains complex modules in which fault diagnosis and repair down to component level are not practical (IMO A.694(17)/8.3.1. Only some discrete components are used. FURUNO Electric Co. Ltd. believes identifying these components is of no value for shipborne maintenance; therefore, they are not listed in this manual. Major modules can be located on the parts location photo on page A-5. FURUNO ELECTRICAL PARTS LIST Sep.
