equipment.
This equipment uses high
voltage electricity which can
shock, burn or cause death.
Only qualified personnel should work inside the
equipment.
Do not dissasemble or modify the
equipment.
Fire, electrical shock or serious injury
can result.
Immediately turn off the power at the
ship's mains switchboard if water or
foreign object falls into the equipment
or the equipment is emitting smoke or
fire.
Continued use of the equipment can
cause fire, electrical shock or serious
injury.
CAUTION
Do not place liquid-filled containers on
the top of the equipment.

The navigator is responsible for checking
all aids available to confirm his position.
Electronic aids are intended to assist, not
replace, the navigator.
Use of an autopilot with this unit, to
provide automatic steering to
destination, does not eliminate the
need to maintain a watch.
Always maintains a vigilant watch to
prevent collision or grounding.

Features
The GP-80 GPS Navigator is a totally integrated GPS receiver and video plotter consisting of a display unit and an antenna unit.
The high sensitivity receiver tracks up to eight
satellites simultaneously. An 8-state Kalman
filter ensure optimum accuracy in determination of vessel position, course and speed.
In most cases the operator need do no more
than turn on the power to find position.
The main features of the GP-80 are
• Comprehensive navigation data displays
• Storage for 999 waypoints and 30 routes
• Alarms: Arrival, Anchor Watch, Crosstrack Error, Ship's Speed, Water Temperature, Depth, and Trip

1.2 Turning On and Off the Power
The GP-80 takes about two minutes to find
position when turned on for the very first time.
Thereafter it takes about 20 seconds to find
position each time the power is turned on.
Turning on the power
Press the [POWER] key.
The unit tests the PROGRAM MEMORY,
SRAM and battery for proper operation and
shows the results on the display. If equipped
with the internal beacon receiver, "BEACON
RCVR INSTALLED" appears at the bottom
of the display. The unit starts up with the last
used display mode.
PROGRAM MEMORY = OK
SRAM = OK
Internal Battery = OK
When turning on the power the following occurs:
20 seconds after turning on the power, accurate position (in latitude and longitude) appears on the display.
If position could not be found, "NO FIX" appears at the GPS receiver condition window.
When PDOP value exceeds 6 in the 3D mode
or HDOP value exceeds 4 in the 2D mode,
"DOP" appears to indicate abnormal fixing
and the position indication could not be updated.
When the satellite signal is being received normally, one of the indications shown in Table
1-1 appears depending on equipment setting
and GPS receiver state.

zoom key is pressed the display range appears
at the center of the display for about three seconds.
2.2 Selecting Display Orientation
Display orientation can be selected on the
Plotter 1, Plotter 2 and Highway displays, with
the [NU/CU ENT] key. Two display orientations are available: north-up and course-up.
North-up display
The cursor moves in the direction of the cursor key pressed. When the cursor reaches the
edge of the display, the display shifts in the
direction opposite.
Data and cursor state
Cursor state determines what data are shown
on the display.

2.4 Shifting the Display
The display can be shifted on the Plotter 1
and Plotter 2 displays, with the [CURSOR
ON/OFF] key. When own ship tracks off the
display it is automatically returned to the
screen center.
1) Press the [CURSOR ON/OFF] key to turn
off the cursor.
2) Press the cursor keys. The display shifts
in the direction of the cursor key pressed.
The GP-80 stores 2,000 points of track and
marks. When the memory becomes full the
oldest track is erased to make room for the
latest. Thus you may want to conserve the
memory when, for example, you are returning to port or are anchored.
Procedure
Press the [PLOT ON/OFF] key to start/stop
recording and plotting of track.
When plotting is resumed
"Resuming track plot" appears at the center

2.9 Selecting Track Plotting Interval
The plotting interval determines both how the
track will be reconstructed on the display and
track storage time. A shorter interval provides
more accurate reconstruction of track line,
however total storage time is reduced. The
plotting interval can be selected by time or
distance. Plotting by distance offers the advantage that the track is not stored when the
vessel is anchored.
5) Enter plotting interval in four digits. To
enter 30 seconds, for example, press [0]

4. NAVIGATION PLANNING
The display changes to Plotter 2 when the
Highway, Navigation or Data mode is in
use.
3) Press the cursor keys to place the cursor
on the location desired for the waypoint.
4.1 Registering Waypoints
In navigation terminology a waypoint is a
particular location on a voyage whether it be
a starting, intermediate or destination
waypoint.
The GP-80 can store 999 waypoints, numbered from 001–999. Waypoints can be registered four ways:
• by cursor
• by MOB position or event position
• at own ship's position, and
• through the waypoint list.
Registering waypoints by the
cursor
1) Press the [WPT R TE] key . The W aypoint/
Route menu appears.

4) Press the [NU/CU ENT] key.
A window similar to the one shown in Fig-
ure 4-3 appears. The waypoint's position
and date and time registered appear on the
first and second lines. Waypoints are automatically given the youngest empty
waypoint number and this number appears
on the third line. You may, however, assign a different number. If the waypoint
shares the same position with a mark, the
mark's position and date and time entered
are registered as waypoint data.
If the waypoint memory is full, the
waypoint number line in the window is
blank. In this case waypoints cannot be
entered unless a waypoint is written over
or deleted.
To assign waypoint number, go to step 5.
If you do not want to change the waypoint
number, go to step 6 to select mark shape
and enter comment.
