Features
The GP-90-DUAL consists of two dual
differential GPS navigator systems and an
interface unit. Each GPS navigator consists
of a display unit combining a GPS receiver,
beacon receiver and video plotter, a GPS
antenna and a beacon antenna. The interface
unit functions to exchange data between the
GPS navigators and external equipment. A
high sensitivity receiver tracks up to 12
satellites simultaneously. An 8-state Kalman
filter ensures optimum accuracy in
determination of vessel position, course and
speed.
The main features of the GP-90-DUAL are
• Comprehensive navigation data displays
• Storage for 999 waypoints and 30 routes
• Alarms: Waypoint Arrival , Anchor Watch,
Cross track Error, Speed, Water
Temperature, Depth, and Trip
• Man overboard feature records lati tude and
longitude coordinates at time of man
overboard and provides continuous
updates of range and bearing to that point.
• Menu-driven operation
• Bright 122 x 92 mm LCD with temperature
compensated tone and brilliance
adjustment
• Power consumption is a low 10 W per
navigator.
• Connection of autopilot (option) - steering
data output to autopilot
• Digital display of water temperature and
depth with connection of video sounder
having IEC 61162-1/NMEA input
• Memory stores 2,000 points of track and
marks.
• 3D "Highway" display shows ship's track
overlaid on intended course.
• Position may be shown in latitude and
longitude or LOP (Loran or Decca).
• Navaid information (lighthouse dat a, lighted
buoys, etc.) can be displayed by
downloading database from personal
computer.
• Fully meets the following regulations:
IMO MSC. 112(73), IEC 61162-2 and IEC
61108-1.

1.2 Turning On and Off the
Power
The GP-90-DUAL takes about 90 seconds to
find its position when turned on for the very
first time. Other times it takes about 12
seconds.
Note: The GPS provides highly accurate
position information. However, position
should always be checked against
other aids to navigation to confirm
reliability, for the safe ty of ve ssel and
crew.
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. "BEACON
RCVR INSTALLED" appears at the bottom of
the display. After the test has been complete d,
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:
12 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 receiving condition
window. When PDOP value exceeds 6 in the
3D mode or HDOP value ex ceeds 4 in the 2D
mode, "DOP" appears to indicate abnormal
fixing and the position indication is not
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.

1.6 The Interface Unit
The Interface Unit IF-2500 outputs data
received from the navigators to external
equipment. Operational status is shown by
the LEDs on the unit. For further details, see
the chapter on installation. For how to select
data to output, see paragraph 8.4 Outputting
Data.
Output data conventions
Since both navigators output data to the
IF-2500 (through two ports on the interface)
confusion would reign if it were to try to
output two sets of mostly identical data.
Therefore, data output is governed by the
following rules:
• When both navigators are outputting data
correctly, data received at the port having
higher priority is output.
• When the GPS abnormal receive signal is
received at the port having higher priority,
data received from the other port is output.
• 30 seconds after data received at the port
having higher priority becomes normal, the
interface unit resumes outputting data
received from that port.
• When data from both navigators is in error,
data received at the port having higher
priority is output.
• Arrival alarm signal or cross track error
alarm is converted to a contact signal and
output when received at the port having
higher priority.
• When no data is received from one or both
navigators, a contact signal is output.

2.8 Track Plotting Interval
The plotting interval determines both how the
track will be reco nstructed on the d isplay 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.

4. NAVIGATION PLANNING
4.1 Entering Waypoints
In navigation terminology a waypoint is a
particular location on a voyage whether it be
a starting, intermediate or destination
waypoint.
The GP-90-DUAL 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.
Waypoints are mutually entered when the
navigators are sharing data.
Entering waypoints by the cursor

4.4 Entering Routes
Often a trip from one place to another
involves several course changes, requiring a
series of route points which you navigate to,
one after another. The sequence of
waypoints leading to the ultimate destination
is called a route. The GP-90-DUAL can
automatically advance to the next waypoint
on a route, so you do not have to change the
destination waypoint repeatedly.
The GP-90-DUAL can store 30 routes and
each route may contain up to 30 waypoints.
Routes can be registered while in the Plotter
1 or Plotter 2 display mode. Routes are
mutually registered when the navigators are
sharing data.

5.4 Finding Range and
Bearing Between Two
Points
Selecting course sailing method
The range and bearing to a destination can
be calculated two ways: Great Circle or
Rhumb Line. However, cross track error is
calculated in rhumb line only.
Great Circle: The great circle courseline is
the shortest course between two points on
the surface of the earth. (I m agi ne s tr etchi ng a
piece of yarn between two points on the
earth.) However, this course requires
frequent change of heading to follow course
faithfully.
Rhumb Line: The rhumb line courseline is
the straight line drawn between two points on
a nautical chart. This course does not require
frequent changes of heading however it is not
the shortest since it follows the earth's
curvature.

When an alarm setting is viol ated, the buzzer
sounds and the name of the alarm being
violated appears on the display. The alarm
icon also appears on the Plotter 1, Plotter 2
and Highway displays. This occurs on both
navigators when they are sharing data.
Alarm status is output to external equipment
through the DATA1 port and the DATA4 port
when it outputs data in NMEA format.

8.1 GPS SETUP Menu
Menu description
Fix mode
Two position fixing modes are available: 2D
and 2/3D. The 2D mode provides two
dimensional position fixes (latitude and
longitude only) and is used when three
satellites are in line of sigh t of the GPS
receiver.
The 2/3D mode switches between two and
three dimension position fixing automatically
depending on how many satellites (three or
four) are in line of sight of the GPS receiver.
ANT Height
Enter the height of the antenna unit above
sea surface (000-999 ft, 000-304 m). The
default setting is 16 ft.
Disable satellite
Every GPS sat ellite is broadcasting
abnormal satellite number(s) in the Almanac.
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. You can disable an
inoperative satellite manually on the GPS
SETUP menu.
GPS smoothing, position
When the DOP or receiving condition is
unfavorable, the GPS f ix may change greatly,
even if the vessel is dead in water. This
change can be reduced by smoothing the
raw GPS fixes. A setting between 0 and 9 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. "0" is the
normal setting; increase the setting if the
GPS fix changes greatly.
GPS smoothing, spe ed
During position fixing, ship’s velocity (speed
and course) is directly measured by
receiving GP S 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 sl ow s. For no s m oothing,
enter "0." "5" is suitable for most conditions.
Speed average
Calculation of ET A and TTG, etc. is based on
average ship’s speed over a given period.
The default setting is one minute. Change
the setting if the ETA seems wrong.
RAIM function/RAIM accuracy
RAIM (Receiver Autonomous Integrity
Monitoring) is a diagnostic function which
tests the accuracy of the GPS signal within
the range set with "RAIM Accuracy" on the
GPS SETUP 2/2 menu. The receiver
displays (provided the RAIM function is
active) three levels of position confidence
according to the results of the test as shown
below. "CAUTI ON " i ndi cates that RAIM could
not be assessed. In this case, provided the
GPS signal is normal, GPS position is safe
to use.
8-1
8. MENU SETTINGS
SAFE: GPS signal is safe to use.
CAUTION: RAIM accuracy is shorter than
protected level or RAIM measurement not
possible.
UNSAFE: GPS signal is not safe to use.
Enter the range for which you want to know
position confidence
Geodetic da tum
Select the geodetic chart system you are
using. WGS-84 (standard GPS chart system)
and NAD 27 can be directly selected. For
other chart s, s elec t " OTH ER " and enter c har t
number referring to the geodetic chart list in
the Appendix.
To output position data to ECDIS (Electronic
Chart Display and Information System), turn
on the power while holding down the [0] key
to disable access to the Geodetic Datum
menu. Then, "Cannot be changed" is shown
in the Geodetic Datum m enu as i n F i gur e 8- 2
on the next page. To stop outputting position
data to ECDIS, turn on the power while
holding down the [0] key.
Position offset
You may apply an offset to position
generated by the internal GPS receiver, to
compensate for difference between GPS
position and chart position.
Time difference
The GPS system uses UTC time. If yo u
would rather use local time, enter the
difference in hours between local time and
UTC. Use the [+] and [-] keys for times later
or earlier than UTC, respectively.
Position
When executing cold start there is no
satellite information in the un it’s memory,
thus it may take some time to find position.
To fix position faster, enter estimated
position.

Besides its fundamental function of
displaying position, the GP-90-DUAL can
also receive data and output data to external
equipment, through an interface unit. Before
outputting data to external equipment, first
determine what data the external equipment
requires. Output only necessary data to
ensure data will be output co rrectly.
All data transmitted by marine electronics
equipment are prefixed with a two-character
code called a talker. The same talker must
be shared by the transmitting and receiving
equipment to transmit and receive data
successfully. The GP-90-DUAL transmits
data using the GP (GPS talker), LC (Loran)

10.3 Antenna Unit
Mounting
Install the antenna unit ref erring to the installation diagram on page D-4. When
selecting a mounting location for the antenna unit, keep in mind the f ollowing
points.
•Select a location out of the radar beam. The radar beam will obstruct or
prevent reception of the GPS satellite signal.
•Be sure the location offers a clean line-of-sight to satellite. Objects within
line-of-sight to a satellite, for exam ple, a mast or funnel, block reception and
cause prolonged acquiring time or interrupt ion of position fix.
•Mount the unit as high as possible. Mounting the antenna as high as
possible keeps it free of water spray, which can interrupt or prevent reception
of GPS satellite signal, if water spray is frozen.
•The antenna unit GPA-018S must be grounded. Connect ground wire of
1.25 sq or larger (local supply) between the ant enna unit and a stainless steel
screw fastened to the mast.

10.5 Initial Settings
The GP-90-DUAL can output navigation information to externa l equipment
through the Interface Unit IF-2500. For example, it can output position data to a
radar or echo sounder for display on their screen.
Before selecting data to output, confirm what data the external equipment
requires. Output necessary data only. Outputting unnecessary data can cause
receiving problems at the external equipment.
Talker
All data transmitted by marine electronics equipment is prefixed with a
two-character code which tells external equipment what equipment is
transmitting data. This two-character code is called the “talker.” The
GP-90-DUAL contains the talkers GP, LC and DE.
Data format and data output availability
