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.

INSTALLATION
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.
Mast
SC-series Antenna
Radar Antenna
Bridge
Example of proper installation
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
10 cm
30 cm
Separation distance (minimum)
1.5 m
3m
-80°
+80°
Separation degrees
• 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).
• 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 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. INSTALLATION
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, indicated by displaying “OK.” (Once almanac
data is stored it takes about five minutes to find heading.) 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. It is suspected that the number of

Antenna
satellites in view is less than five due to
Element
signal blockage. Clear the problem and

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. The setting
range is from 0 (no smoothing) to 999 seconds, and the default is 5 s, which is
good for rolling period o 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.
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

To restore a satellite, enter “00”.

Heading Heading data in either AD10 or IEC 61162 (NMEA
0183) format (4800 bps) is automatically received.
Priority of IEC 61162 (NMEA 0183) sentence is
HDT>HDG>HDM.
The signal is selected through the menu during the
period of internal heading sensor failure.
VBW/VHW/VLM may be input from a current indicator.
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.

APPENDIX
Parts List
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. Major modules can
be located on the parts location photo on page A-5.
