Output sentence limitations - IEC 61162-1/2 format (typically compatible with NMEA sentences)
The number of sentences that can be output depends on baud rate and output interval settings. The maximum number of characters per data sentence is shown in the table below. Sentences included are HDT, HDM, ROT, ATT, VDR, VTG, GGA, GNS GLL, VHW, VBW, HVE, ZDA
The number of characters that can be output N is calculated by the following formula: N < 0.083 x T x B (Where T = Interval [in seconds] and B = Baud rate (4800 default), 9600, 19200 or 38400

INSTALLATION

Mounting Considerations

Antenna unit
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.

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.
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.

1. INSTALLATION

The horizontal separation between the antenna and masts must be as follows:
Mast diameter 10 cm 30 cm
SC-50s antenna Horizontal separation distance

Mast, etc.

Separation distance (minimum) 1.5 m 3m
Mast, etc. Less than 10 TOP VIEW
Horizontal separation between antenna and masts
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.

Example of antenna installed below superstructures
Display unit, processor unit
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 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.
Installing the Antenna Unit

Antenna unit SC-303

Note: Bird-repellent fixtures (supplied) may be attached to the antenna cover to prevent birds from alighting on the cover. If it is more convenient to attach them before fixing the antenna unit to the mounting location, do step 9 before fixing the antenna unit.
Fasten the antenna to the mounting location lastly if it is more convenient to connect the antenna cable before mounting the antenna unit.
1. Prepare a mounting platform (wood, steel or aluminum) in accordance with the illustration shown below. If corrosive material is used, take necessary anti-corrosion measures. Note: When drilling holes in the platform, be sure they are parallel with the fore-and-aft line. 2. Orient the unit so the two lines on the base is facing the bow and then fasten the antenna unit to the platform with four sets of M10 hex. bolts, spring washers and flat washers. (The installation error should be within 2.5.) The torque for the hex. bolts should be between 20 2Nm.
Do not open the antenna. This installation does not require removal of the antenna cover.

"OK" displayed when the "GOOD" column shows that the number of satellites acquired is five or more.
"3D" shown when no beacon receiver is used. "W3D" shown when receving WAAS.
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.

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 No. of Characters HDT 19 HDM 19 THS 21 ROT 21 ATT 34 HVE 23 VTG* 46 GGA* 66 GNS* 62 GLL* 47 ZDA* 36 VHW* 44 VBW* 45 VDR* 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.

4. Parts List and Parts Location
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 shipboard maintenance; therefore, they are not listed in the manual. Major modules can be located on the parts location photo on this and then next page.

6. 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 + n where is 19 cm. n is automatically found during the initialization stage by receiving three satellites. A fraction of a carrier wavelength, , is processed by FURUNOs 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.

7. What is WAAS?
WAAS, available in North and South America mainly, 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. There are three more SBAS providers, MSAS (Multi-Functional Satellite Augmentation System), EGNOS (Euro Geostationary Navigation Overlay Service) and GAGAN (GPS Aided Geo Augmented Navigation). All providers are compatible with one another, thus providing seamless position fixes to SBAS users. The illustration below shows the coverage area of the SBAS. (Accuracy may be affected when using a GEO satellite not within your current location.) This manual uses WAAS for these three providers generically.
