In reality, a third antenna is used to reduce the influence of pitch, roll and yaw, and five satellites are processed to obtain 3D data. If the GPS signal is blocked by a tall building or the vessel is under a bridge, the 3-axis solid-state angular rate gyros in the processor unit take place of the satellite compass, maintaining the current heading continuously.
INSTALLATION 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.
Page 16
2. INSTALLATION The horizontal separation between the antenna and masts must be as follows: Mast diameter Separation distance (minimum) 10 cm 30 cm 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).
Locate the antenna above the radar antenna, out of the radar beam. Sc-series Antenna Example of improper installation Location influenced by reflected wave. NO! UNSUITABLE LOCATION SC-series antenna located below all other structures 2.1.2 Display unit, processor unit Choose a location where vibration and shock are minimal. Install the units well away from locations subject to rain and water splash.
2. INSTALLATION Installing the Antenna Units 2.2.1 SC-series antenna unit 1. Prepare an installation post for the antenna in accordance with the illustration shown below. Recommended Flange (Option) Name: Flange Type: OP20-31 Code No.: 004-378-230 Weld all the way around. Post should be constructed from stainless steel and measure 4mm or larger in thickness.

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 with Three Bond 1211 (supplied). 5. Coat bolt threads with Three Bond 1211. Fasten bolts with nuts.
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.
Page 22
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.
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. 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. 3.

LOG/ALARM HDG IN Note: Each GPS receiver GPS1, GPS2, and GPS3 calculates VTG/GGA/GLL/ZDA. The output from HDG OUT and NAV OUT ports is one calculated by the GPS1. However, when the GPS1 is defective, the GPS2 replaces it. When both GPS1 and GPS2 are defective, the data calculated by the GPS3 is used.
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.
