WHAT IS WAAS?

WAAS, available in North America, is a provider in t he worldwide SBAS (Satellite Based Augmentation System) navigation system. An SBAS pr ovider furnishes GPS signal corrections to SBAS users. 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 providers will be compatible with one another, thus providing “seamless” position fixes to SBAS users.

At the time of this software release, SBAS is still under development. (Providers are expected to have initial operations capability from the times shown above.) During this developmental period, which may last for several years, there is no guarantee of the accuracy, int egrity, continuity, or availability of the SBAS signal. Furuno will accept no responsibility f or the use of the signal for other than the above stated purpose. It is t he user’s responsibility to exercise common prudence and navigational judgment while using the SBAS signal in the developmental phase.

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

The GP-1850WDF/1850WF takes about 90 seconds to find its position when turned on for the very first time. This is because the equipment has no satellite data, called the Almanac, in its database. If you want to lessen the time needed to find position you may enter your position manually (default position: San Francisco, USA) on the GPS SETUP OPTIONS menu.

Thereafter it takes about 12 seconds to find position each time the power is turned on.

2. VIDEO SOUNDER OPERATION

2.1 Principle of Operation

The video sounder determines the distance between its transducer and underwater objects such as fish, lake bottom or seabed and displays the results on screen. It does this by utilizing the fact that an ultrasonic wave transmitted through water travels at a nearly constant speed of 4800 feet (1500 meters) per second. When a sound wave strikes an underwater object such as fish or sea bottom, part of the sound wave is reflected back toward the source (transducer). Thus by calculating the time difference between the transmission of a sound wave and the reception of the reflected sound wave, the depth to the object can be determined.

The entire process begins in the display unit. Transmitter power is sent to the transducer as a short pulse of electrical energy. The electrical signal produced by the transmitter is converted into an ultrasonic signal by the transducer and transmitted into the water. Any returning signals from intervening objects (such as a fish school) are received by the transducer and converted into an electrical signal. The signals are then amplified in the amplifier section, and finally, displayed on screen.

The picture displayed is made up of a series of vertical scan lines, one for each transmission. Each line represents a snapshot of what has occurred beneath the boat. A series of snapshots are accumulated side by side across the screen, and the resulting contours of the bottom and fish between the bottom and surface are displayed.

50 kHz picture

The sounder uses ultrasonic pulses to detect bottom conditions. The lower the frequency of the pulse, the wider the detection area. Therefore, the 50 kHz frequency is useful for general detection and judging bottom condition.

200 kHz picture

The higher the frequency of the ultrasonic pulse the better the resolution. Therefore, the 200 kHz frequency is ideal for detailed observation of fish school.

2.5 Automatic Sounder Operation

2. VIDEO SOUNDER OPERATION

Dual-frequency display: Press the

MODE soft key.

Automatic sounder operation is useful when you are preoccupied with other tasks and do not have time to adjust the display.

How the automatic sounder works

The automatic sounder function automatically selects the proper gain, range scale and clutter suppression level according to depth. It works as follows:

• Range changes automatically to display

the bottom echo on the screen.

• The gain is automatically adjusted to

display the bottom echo in reddish brown (default color arrangement).

• Clutter, which suppresses low level noise,

is automatically adjusted.

Two types of automatic sounder modes

Two types of automatic sounder modes are available: CRUISING and FISHING. CRUISING is for tracking the bottom, and FISHING is for searching fish schools. CRUISING uses a higher clutter rejection setting than FISHING therefore it is not recommended for fish detection - weak fish echoes may be erased by the clutter suppression circuit.

How to enable automatic sounder operation

1. To show the mode/freq window:

Normal sounder display: Press the

MODE/FREQ soft key.

Plotter/sounder display: Press the

SNDR, MODE/FREQ soft keys in order.

3. Press the RETURN soft key to close the window, or wait 10 seconds and the window closes automatically.

2.6 Manual Sounder

Operation

Manual operation is useful for observing fish schools and bottom using a fixed gain setting.

The gain, clutter, range and range shifting functions used together give you the means to select the depth you can see on screen. The basic range can be thought of as providing a “window” into the water column and range shifting as moving the “window” to the desired depth.

Selecting the manual mode

1. Press the appropriate soft keys to show the MODE/FREQ window.

2. Select MANUAL.

3. Press the RETURN soft key.

Zero line

Shift

Zero line

Minute mark

Minute mark shows time with two colored bar. Each bar is 30 sec.

Fish school echoes

Fish school echoes will generally be plotted between the zero line and the bottom. Usually the fish school/fish echo is weaker than the bottom echo because its reflection property is much smaller compared to the bottom. The size of the fish school can be ascertained from the density of the display.

Echoes from the bottom are normally the strongest and are displayed in reddish-brown color but the color and width will vary with bottom composition, water depth, frequency, sensitivity, etc.

In a comparatively shallow depth, a high gain setting will cause a second or sometimes a third or a fourth echo to be displayed at the same interval between them below the first echo trace. This is because the echo travels between the bottom and the surface twice or more in shallow depths.

The color of the bottom echo can be used to help determine the density of the bottom materials (soft or hard). The harder the bottom, the wider the trace. If the gain is set to show only a single bottom echo on mud, a rocky bottom will show a second or third bottom return. The range should be chosen so the first and second bottom echoes are displayed when bottom hardness is being determined.

2. VIDEO SOUNDER OPERATION

Surface noise/Aeration

When the waters are rough or the boat passes over a wake, surface noise may appear near the zero line. As surface turbulence is acoustically equivalent to running into a brick wall, the bottom echo will be displayed intermittently. Similar noise sometimes appears when a water temperature difference (thermocline) exists. Different species of fish tend to prefer different temperature zones, so the thermocline may be useful to help identify target fish. 200 kHz tends to show shallow thermoclines better than 50 kHz.

In rough waters the display is occasionally interrupted due to below-the-ship air bubbles obstructing the sound path. This also occurs when the boat makes a quick turn or reverses movement. Lowering the picture advance speed may reduce the interruption. However, reconsideration of the transducer installation may be necessary if the interruption occurs frequently.
