1.1 Mounting the Antenna Unit

1.1.1 Mounting considerations for single antenna

General

• Keep the length of the antenna cable in mind when selecting a mounting

location. Do not shorten the antenna cable.

• The location should not be where movement is different from ship’s

movement.

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

Radar Antenna

Bridge

Antenna

Example of antenna installed above all superstr uct ures

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.

"OK" displayed when the "GOOD" column shows that the number of satellites acquired is five or more.

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 12 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. (For the open-type antenna, loosen the nut at the center of the antenna unit to adjust antenna orientation.) 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.

2.7.2 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. The higher the setting the more smoothing. However, too high a setting slows updating of position.

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.

2. OPERATION

2-9

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”.

Output sentence limitation

The number of sentences which can be output depends on baud rate and output interval settings. The maximum number of characters per each data sentences are shown in the table below and the total number of characters must satisfy the formula shown below. The number of characters which can be output “N” is calculated by the following formula

N <

0.083 x T x B

T: Interval (s) B: Baud rate

Sentence and maximum number of characters

Sentence HDT HDM ROT ATT HVE VTG* GGA* GNS* GLL* ZDA* VHW* VBW* VDR＊

No. of Characters

19 19 21 34 23 46 66 62 47 36 44 45 35

*: Output is 1 s if interval set is shorter than 1 s.

For example, the baud rate is 4800 bps, interval is 100 ms (= 0.1 s). Therefore, the number of characters is N <0.083 x 0.1(s) x 4800(bps) = 39.4.

Then, the number of characters which can be output is 39. For sentences (sentences not having an asterisk in the table) where the output interval is variable the number of characters is as shown in the table, however sentences where the output interval is not smaller than 1 s (asterisk-marked sentences in table) the number of characters which can be output is “number of characters in table” x “setting interval.”

For the above settings the following applies:

• If both HDT and HDM are selected the total number of characters is 19+19 =

38. Since the count is less than 39 both can be selected.

• If both HDT and VTG are selected the total number of characters is

19+46x0.1=23.6. Since the count is less than 39 both can be selected.

• If HDT, HDM and VTG are selected the total number of characters is

19+19+46x0.1=42.6. In this case, the message “SENTENCE OVERLOAD” appears.

Principle of Satellite Compass

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.

What is WAAS?

WAAS, available in North America, is a provider in the worldwide SBAS (Satellite Based Augmentation System) navigation system. SBAS provides GPS signal corrections to SBAS users, for even better position accuracy, typically better than three meters. Two more SBAS providers are also currently under development, MSAS (Multi-Functional Satellite Augmentation System) for Japan and EGNOS (Euro Geostationary Navigation Overlay Service) for Europe. All provides will be compatible with one another, thus providing “seamless” position fixes to SBAS users.

At the time of this software release, only WAAS is operational. During the developmental period in other areas, which may last for several years, there is no guarantee of the accuracy, integrity, continuity, or availability of the SBAS signal. FURUNO will accept no responsibility for the use of the signal for other than the above stated purpose. It is the user’s responsibility to exercise common prudence and navigational judgment while using the SBAS signal.

Note: This manual uses “WAAS” when referring to any SBAS provider.
