FOREWORD

A Word to the Owner of the SC-60

FURUNO Electric Company thanks you for purchasing the FURUNO SC-60 Satellite Compass. We are confident you will discover why the FURUNO name has become synonymous with quality and reliability.

For over 50 years FURUNO Electric Company has enjoyed an enviable reputation for quality and reliability throughout the world. This dedication to excellence is furthered by our extensive global network of agents and dealers.

Your satellite compass is designed and constructed to meet the rigorous demands of the marine environment. However, no machine can perform its intended function unless properly installed and maintained. Please carefully read and follow the operation, installation and maintenance procedures set forth in this manual.

We would appreciate feedback from you, the end-user, about whether we are achieving our purposes.

Thank you for considering and purchasing FURUNO.

Features

The SC-60 is a new satellite compass designed with FURUNO’s advanced GPS kinematic technology. This compass finds a wide range of applications for any type of ships and mobile units at sea or on land.

The main features are

•Perfect for use as heading sensor for Radar/ARPA, AIS, ECDIS, scanning sonar, and video plotter

•There are no mechanical parts such as gimbals or rotating motor, thus the compass is free from routine maintenance

•The performance is not affected by geomagnetism thus it is suitable for use on any vessel

•No need for speed correction like a gyrocompass

•Short settling time - three minutes

•Provides all necessary functions as a GPS navigator.

iv

SYSTEM CONFIGURATION

The SC-60 consists of an antenna, a display unit and a processor unit. The antenna is available in a low-profile radome type antenna accommodating three antenna/receiver unit, or discrete type. The tri-antenna system helps reduce the influence of ship's motion (rolling).

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. “n” is automatically found during the initialization stage by receiving three satellites. A fraction of a carrier wavelength, ∆λ , is processed by FURUNO’s advanced kinematic technology in geographical survey, thus determining a vector (range and orientation) A1 to A2.

In reality, a third antenna is used to reduce the influence of pitch, roll and yaw, and five satellites are processed to process 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.

2 INSTALLATION

2.1Mounting Considerations

2.1.1SC-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).

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. Failure to do so will cause shadows and multipath reflection problems.

Mast

SC-series Antenna

RadarAntenna

Bridge

Example of antenna installed above all superstructures

Installing the antenna below superstructures

If it is not possible to mount the antenna above all superstructures on the vessel, as shown in the illustration above, shading and multipath problems may occur on at least one heading, and possibly more. To possibly avoid those problems, observe the guidelines in this section.

NOTICE

If the antenna is installed below any superstructure, the installation must

be done over a two-day period, following the procedure in the service manual.

At least 12 hours are required to capture tracking data to measure multipath indexes and locate areas of shading.

2-1

2.INSTALLATION

•The horizontal separation between the antenna and masts must be as follows:

Mast diameter	Separation distance (minimum)
10 cm	1.5 m
30 cm	3 m

Horizontal separation distance

Mast, etc.

Horizontal separation between antenna and masts

•The field of view above the antenna should be as shown below, ±80° against zenith. To avoid reflections from masts and the like, locate the antenna well away from the shadows of the radar mast, etc.

2.1.2Display 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.

•Locate the units away from air conditioner vents.

•Keep the units out of direct sunlight because of heat that can build up inside their cabinets.

•Choose a well-ventilated location.

•For the display unit, choose a location where it can be easily operated.

•Leave sufficient space around the units to permit access for maintenance. See the outline drawing for recommended maintenance space.

2.2Installing the Antenna Units

2.2.1SC-series antenna unit

NOTICE

Fasten the antenna to the mounting location lastly if it is more convenient to connect the antenna cable before mounting the antenna unit.

1.Prepare a mounting platform (wood, steel or aluminum) in accordance with the illustration shown below. If corrosive material is used, take necessary anti-corrosion measures.

Note: When drilling holes in the platform, be sure they are parallel with the fore-and-aft line.

2.Fasten the antenna unit to the platform with four sets of M10 hex. bolts, spring washers and flat washers, orienting it as shown below. (The bow mark

( ) on the antenna should face the bow.) The torque for the hex. bolts should be between 19.6-24.5 Nm.

NOTICE

Do not open the antenna.

This installation does not require removal of the antenna cover.

•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.

•Fasten it to a steel post (φ 35-φ 90) with stainless steel hose clamps (supplied).

2.3.4Adjusting for orientation error

It may be impossible to perfectly align the processor unit on the fore-and-aft or port-and-starboard line. Open the top cover, loosen the two fixing screws on the angular rate sensor and turn. For example, if the orientation error is 2.5° to port, rotate the sensor 2.5° starboard. The range of adjustment is -45° to +45°. Close the top cover after completing the adjustment.

General wiring diagram

•The display cable (display and processor units) is 10 m long. Connect it to the DISPLAY port on the processor unit.

•The antenna cable is 15 meters (standard length). Connect the three coaxial cables to the processor unit according to cable color as below. Incorrect connection will result in wrong heading.
