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.

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).

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

Example of antenna installed above all superstr uct ures

Radar Antenna

Bridge

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.

NOTICE

2-1

2. INSTALLATION

•

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

•

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.

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 satellites in view is less than five due
to signal blockage. Clear the problem and then check status on the status
display.

If the heading error is between 5° and 10°, loosen the nut at the center of the
antenna unit and adjust antenna orientation, while watching the heading
indication on the display.

3.7.2 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 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,
