switchboard if the equipment is emitting
smoke or fire.
Continued use of the equipment can cause
fire or electrical shock. Contact a FURUNO
agent for service.
Do not place liquid-filled containers on
the top of the processor unit.
WARNING
Do not open the cover unless totally
familiar with electrical circuits and
service manual.
Improper handling can result in electrical
shock.
Turn off the power at the switchboard
before beginning the installation.
Fire or electrical shock can result if the
power is left on.
Do not install the equipment where it
may get wet from rain or water splash.
Water in the equipment can cause fire,
electrical shock or damage to the equipment.
Fire or electrical shock may result if the
liquid enters the equipment.
CAUTION
No one navigation device should ever
be solely replied upon for the navigation
of a vessel.
Always confirm position against all available aids to navigation, for safety of vessel
and crew.
Use the proper fuse.
Use of a wrong fuse can result in damage
to the equipment.

FURUNO Electric Company thanks you for purchasing the FURUNO SC-120
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 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-120 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 - four minutes
•
Provides all necessary functions as a GPS navigator.
iv
SYSTEM CONFIGURATION
The SC-120 consists of three SC-series antennas, a display unit and a
processor unit. 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 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.

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

Exam ple of proper installat ion
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.
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.

• 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 well 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.

2.3.4 Adjusting 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.
