1. OPERATIONAL OVERVIEW

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. OPERATIONAL OVERVIEW

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.

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

Way points are automatically given the youngest empty waypoint number and this number appear s on the third line. You may, however, assign a different num ber. If the waypoint shares the same positi on with a mark, the mark's position and dat e and time entered are registered as waypoint data.

If t he 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 ov er or er ased.

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. MENU SETTINGS

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) or DE (Decca) talker.

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.
