WHAT IS WAAS?
WAAS, available in North America, is a provider in the worldwide SBAS (Satellite Based
Augmentation System) navigation system. An SBAS provider 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, 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 in the developmental phase.
Note: This manual uses “WAAS” when referring to any SBAS provider.

START UP TEST
Start-up sequence
For any NG on the start up test display,
request service.
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
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.
Dual-frequency display: Press the

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.

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.
Small

Large

Size of

Fish school echoes
Bottom echo
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.

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.

6. WAYPOINTS
6.1 Entering Waypoints
In navigation terminology, a waypoint is a
particular location on a voyage whether it be
a starting, intermediate or destination point.
A waypoint is the simplest piece of
information your equipment requires to get
you to a destination, in the shortest distance
possible. This unit has 835 waypoints
(including quick waypoints) into which you
can enter position information. There are five
methods by which you can enter a waypoint:
at own ship’s position, at MOB position, by
cursor, by range and bearing, and through
the waypoint list (manual input of latitude
and longitude).
Entering waypoints at own ship’s
position
You can save your current position as a
waypoint. Press the [SAVE/MOB] key with a
touch-and-release action to store your
position. This new waypoint will
automatically be saved in the waypoint list
under the next consecutive waypoint
number.
For FISHING 2 mode, immediately after
pressing the MOB key, you can change the
mark shape, color etc. similar to that shown
in the procedure on the next page. Press the
SAVE soft key to enter the mark.
Entering waypoints at MOB position
The MOB mark functions to mark man
overboard position.
1. At man overboard, press the
[SAVE/MOB] key several seconds to
display the following message.
MAN OVER BOARD!
GO TO (MOB)?
YES ... "ENTER" key
NO ... "CLEAR" key
MOB message
2. Press the [ENTER] key to select MOB
position as destination, or the [CLEAR]
key to only mark MOB position.
3. To show range and bearing to the MOB
position, press the soft key NAV L/L
followed by the soft key NAV WPT.

the waypoint it is registered under and the
MOB mark itself. Place the cursor on the
MOB mark and press the [CLEAR] key
followed by the [ENTER] key to erase the
waypoint. (A flashing diamond appears over
the waypoint when it has been correctly
selected.) Repeat to erase the MOB mark.

Often a trip from one place to another
involves several course changes, requiring a
series of route points (waypoints) which you
navigate to, one after another. The sequence
of waypoints leading to the ultimate
destination is called a route. Your unit can
automatically advance to the next waypoint
on a route, so you do not have to change the
destination waypoint repeatedly.
You can store up to 200 routes. A route may
consist of 35 points.

BEARING
A navigation device outputs both true and
magnetic bearings. A magnetic bearing is
true bearing plus (or minus) earth’s magnetic
deviation. Thus the equation for finding
magnetic bearing is;
true bearing ±x (magnetic variation)° =
magnetic bearing
You can display your ship’s course and
bearing to waypoint in true or magnetic
bearing.

4. Press the ENTER soft key or the
[ENTER] key to register your selection.
POS SMOOTHING
When the DOP or receiving condition is
unfavorable, the GPS fix may change, even
if the vessel is dead in water. This change
can be reduced by smoothing the raw GPS
fixes. A setting between 000 to 999 is
available. The higher the setting, the more
smoothed the raw data, however too high a
setting slows response time to change in
latitude and longitude. This is especially
noticeable at high ship’s speeds. 000 is the
normal setting; increase the setting if the
GPS fix changes.
SPD/CSE SMOOTHING
During position fixing, ship’s velocity (speed
and course) is directly measured by
receiving GPS satellite signals. The raw
velocity data may change randomly
depending on receiving conditions and other
factors. You can reduce this random
variation by increasing the smoothing. Like
with latitude and longitude smoothing, the
higher the speed and course smoothing the
more smoothed the raw data. If the setting is
too high, however, the response to speed
and course change slows. For no smoothing,
enter all zeroes. The default setting is 005
(sec).
GPS SPEED AVE
Calculation of ETA is based on average
ship’s speed over a given period. If the
period is too long or too short calculation
error will result. Change this setting if
calculation error occurs. The default setting
is 60 seconds, which is suitable for most
conditions.
LAT OFFSET, LON OFFSET
GPS-generated position may be off from the
chart. In this case, you can apply an offset to
GPS position to refine position accuracy.
Mark the equipment indication on the chart,
and then calculate the L/L error.
1. Select LAT OFFSET or LON OFFSET.
2. Press the EDIT soft key.
3. Key in the error value. To switch the
north and south (east and west), press
the N<->S (W<->E) soft key.
4. Press the ENTER soft key or [ENTER]
key.
DISABLE SATELLITE
Every GPS satellite is broadcasting
abnormal satellite number(s) in its Almanac,
which contains general orbital data about all
GPS satellites, including those which are
malfunctioning. 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 about a malfunctioning satellite
from another source, you can disable it
manually. Enter satellite number (max. 3
satellites) in two digits and press the ENTER
soft key or the [ENTER] key.

the alarm, LOW, any echo (greater than
light-blue) triggers the alarm.
TX POWER: Turns TX power on/off.
TVG 200kHz, TVG 50kHz: TVG (Time
Varied Gain) compensates for propagation
attenuation of the ultrasonic waves. It does
this by equalizing echo presentation so that
fish schools of the same size appear in the
same density in both shallow and deep
waters. In addition, it reduces surface noise.
Note that if the TVG level is set too high
short range echoes may not be displayed.

If the on-screen echo level appears to be too

If the depth indication is unstable in
automatic operation or the bottom echo
cannot be displayed in reddish-brown by
adjusting the gain control in manual
operation, you may adjust the bottom echo
level detection circuit, for both 50 kHz and
200 kHz, to stabilize the indication. Note that
if the level is set too low bottom echoes
cannot be acquired and if set too high
regards the fish school as the bottom, so the
depth indication will not be fixed. The default
setting for both 200 kHz and 50 kHz is 80.
