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, 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
• Meets the following requirements: IMO MSC. 116(73), ISO/FDIS 22090-3,
IMO A. 694(17), IEC 60945 (2002-08), IEC 61162 (2000).

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).

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.

INSTALLATION

2.1

Mounting Considerations

2.1.1

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 view of the satellites regardless of vessel heading.
Failure to do so will cause shadows and multipath reflection problems.
Mast
SC-series Antenna
Radar Antenna

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:

Satellite tracking status display
When the system is turned on for the first time it is in the “cold-start” state, which
means there is no satellite data (almanac data) stored. In this condition it takes
about 20 minutes to find heading. When heading is found the display shows
“OK.” The timer at the top left corner of the screen shows time since power on. If
OK is not displayed within 30 minutes after turning on the power, the antenna
mounting location may not be suitable. Suspect that the number of satellites in
view is less than five due to signal blockage. Resolve the problem and then
recheck tracking status.
If the heading error is between 5° and 10°, adjust orientation of the antenna unit,
while watching the heading indication on the display. (For the open-type antenna,
loosen the nut at the center of the antenna unit to adjust antenna orientation.)

GPS SETUP menu description
SMOOTH POS (Smoothing position)
When the DOP (Dilution of Precision, the index for position-fixing accuracy) or
receiving condition is unfavorable, the GPS fix may change randomly, even if the
vessel at anchor. This change can be smoothed by averaging a number of GPS
fixes. The setting range is from 0 (no smoothing) to 999 seconds, and the default
is 5 s, which is good for rolling period of 5-8 s. The higher the setting the more
smoothing. However, too high a setting slows updating of position. “0” is the
default setting; increase the setting if the GPS fix fluctuates largely.
SMOOTH S/C (Smoothing speed/course)
Ship’s speed and course are directly measured by receiving GPS satellite
signals, independent of positions. The data varies with receiving conditions and
other factors. You can reduce this random variation by increasing the smoothing.
The higher the setting the more that speed and course are smoothed. If the
setting is too high, however, the follow-up to actual values gets slower. The
setting range is from 0 (no smoothing) to 999 seconds.
LAT/LON OFFSET (L/L position offset)
If GPS fixes are erroneous while at anchor, enter a position offset to compensate
for position error. Consult a nautical chart to determine latitude and longitude
differences between the chart and GPS display. Enter that value as the offset.

3-8

3. OPERATION

DISABLE SV (Disable satellite)
Every GPS satellite is broadcasting abnormal satellite number(s) in its Almanac,
which contains general orbital data about all GPS satellites. Using this
information, the GPS receiver automatically eliminates any malfunctioning
satellite from the GPS satellite schedule. However, the Almanac sometimes may
not contain this information. If you hear of an inoperative satellite you can
disable it manually. Enter satellite number in two digits and then press the [ENT]
key. To restore a satellite, enter “00”.

4.1

Preventive Maintenance
Regular maintenance is important for good performance. A maintenance
program should be established and should include the following points.

• Check connectors and ground terminal on the processor unit and display unit
for tightness.
• Check ground terminal for rust. Clean or replace as necessary.
• Check for water leakage in the antenna cable. Replace the cable if there are
signs of water leakage.
• Remove dust and dirt from the display unit (including LCD) and processor unit
with a dry, soft cloth. Wipe the LCD carefully to prevent scratching, using
tissue paper and an LCD cleaner. To remove stubborn dirt, use an LCD
cleaner, wiping slowly with tissue paper so as to dissolve the dirt. Change
paper frequently so the dirt will not scratch the LCD. Do not use chemical
cleaners for cleaning - they can remove paint and markings.
