FOREWORD
A Word to the Owner of the SC-50
FURUNO Electric Company thanks you for purchasing the FURUNO SC-50
THD Satellite Compass. (Hereafter, for sake of brevity, we refer to the SC-50 as
Satellite Compass.) We are confident you will discover why the FURUNO name
has become synonymous with quality and reliability.
For over 60 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-50 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
• 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
• Meets the following requirements: IMO MSC. 116(73), ISO/FDIS 22090-3,
IMO A. 694(17), IEC 60945 (2002-08), IEC 61162-1 3rd Ed.2007-04.

vi
SYSTEM CONFIGURATION
The SC-50 consists of an antenna, a display unit and a processor unit. The
tri-antenna system accommodates three antennas/receiver units and is available
in a low-profile radome type or open type. The tri-antenna system helps reduce
the influence of ship's motion (rolling).

1 INSTALLATION
1.1 Mounting Considerations
1.1.1 Antenna unit
General
• Keep the length of the antenna cable in mind when selecting a mounting
location.
Installing the antenna above superstructures
• The antenna must be mounted above all other structures on the vessel to
obtain an unobstructed viewof the satellites regardless of vessel heading.
Failure to do so will cause shadows and multipath reflection problems.
Mast
Radar Antenna
Bridge
SC-series Antenna
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.

1. INSTALLATION

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

10 cm 1.5 m
30 cm 3 m

• 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.

• 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.

1.2 Installing the Antenna Unit
1.2.1 Antenna unit SC-303
Note:“Bird-repellent fixtures” (supplied) may be attached to the antenna cover to
prevent birds from alighting on the cover. If it is more convenient to attach
them before fixing the antenna unit to the mounting location, do step 9
before fixing the 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. Orient the unit so the two lines on the base is facing the bow and then fasten
the antenna unit to the platform with four sets of M10 hex. bolts, spring
washers and flat washers. (The installation error should be within ±2.5°.) The
torque for the hex. bolts should be between ±20 2Nm.

antenna mast after confirming that the installation site is suitable, following
paragraph 2.6.)
Note: If U-bolts are used to temporarily fix the pedestal and support plate,
DO NOT overtighten them – overtightening may deform the pedestal.
