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.

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.

superstructure, the installation must  
be done over a two-day period, following  
the procedure in the service manual.  
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.  
At least 12 hours are required to capture  
tracking data to measure multipath indexes  
and locate areas of shading.

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. 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”.
