INTRODUCTION TO GPSPLUS

The GPSPlus display unit processes the information from its accurate 12 channel GPS antenna/receiver unit or from an additional LORAN-C or DECCA receiver. The unit can select between either of the two input devices to display accurate positional information, along with waypoints, routes and information concerning GPS satellites, LORAN-C T.D.'s or DECCA L.O.P.'s.

GPSPlus ALARMS

The GPSPlus display has alarms that can be set and adjusted to suit your requirements. When an alarm condition is met the internal alarm buzzer will sound and the display will indicate which alarm has been triggered. When the GPSPlus is part of a fully integrated Network Instrument system the alarm conditions will be displayed and sounded by all Network display units.

The GPSPlus display will also repeat alarms from Network instruments when part of an integrated Network System.

Refer to the SETTING UP THE GPSPlus for details on setting and adjusting the alarms.

INTRODUCTION

After installation the GPSPlus can be used immediately with minimal setting up for basic operation. To use the advanced features of the GPSPlus display it is necessary to program various parameters and enter waypoints and routes into the units library. These will be discussed in later sections of this handbook.

SWITCHING ON

The GPSPlus will power up and start receiving and processing the signals from the satellites when the switch or contact breaker for your instruments supply is turned on. The display unit does not have an ON/OFF switch.

INITIAL DISPLAYS

On power-up the unit will show its satellite receiving status:

On subsequent power-ups the GPSPlus should quickly obtain enough satellites for a fix, and the WAIT message will only be displayed momentarily. If after a period of 15 minutes the display still shows NO DATA then check your installation. If everything seems to be in order consult your dealer.

The GPSPlus system requires only three satellites to obtain a `fix'. When the unit has obtained a fix (in GPS mode) the display will show the following:

If the GPSPlus display has not been programmed with any navigational data (i.e. waypoints or routes) only the POS key gives useful information.

When a brand new unit is powered up for the first time, or if the unit has moved more than 1500km since it was last powered up, it may take up to an hour to acquire enough satellites for a fix.

Your GPSPlus has the ability to be used with a secondary position fixing device, either a LORAN-C or a DECCA. The unit will initially power-up using its own GPS antenna/receiver unit. Selecting LORAN-C or DECCA receiver will be explained later in this manual. Once selected the GPSPlus will always power-up using the selected receiver.

USING THE LIGHTS KEY

The GPSPlus display unit has 3 levels of illumination and off, controlled by the LIGHTS key. It also changes the illumination level of the key legends. The LIGHTS key is always illuminated so even in complete darkness the key can be located.

NOTES ABOUT ENTERING DATA

INTRODUCTION TO WAYPOINTS

A "waypoint" is simply a point you wish to go to. It can be an anchorage, a point off a landmark, buoys, harbour entrances or any position at sea. Whatever the waypoint, it is necessary to know its position in latitude and longitude or determine its range and bearing from your present position. This can be taken directly from your chart.

The GPSPlus display can store 250 waypoints in its memory, this is commonly called a waypoint library. The waypoints are given unique numbers, and can also be named, so they can be recalled when required. After a time your waypoint library will contain all your most commonly used navigational points. The waypoints in the library can be edited if required, i.e. copied, named and deleted. This will be necessary if you have used all of the 250 waypoint library locations. Until at least one waypoint has been entered into the GPSPlus library defining a route the advanced navigational features obtained by pressing the NAV key are not available.

ENTERING WAYPOINT DATA

Waypoints can be entered into the waypoint library of the GPSPlus unit in many ways. The following is a list of these methods:

1. Mark facility, one-touch waypoint entry.

2. Entry of waypoint latitude and longitude.

3. Entry of present position as a waypoint.

4. Copying from a library waypoint to another.

5. Entry by range and bearing from another waypoint.

6. Copying or "uploading" from another position fixer.

NAMING WAYPOINTS

It is possible to give any waypoint a name. This could be the charted name of buoys, navigational markers, or any unique name you wish to use. The name must not exceed eight characters in length and can be any combination of letters, numbers, spaces and the symbols <, >, /. All spaces count as characters. For example:

BUOY, <BUOY>, 123/BUOY, B U O Y The following words are reserved for use by the GPSPlus

unit and can not be used as waypoint names:

INSERT DELETE START END

All waypoints can be named before or after their position has been entered. This allows you to generate a list of library names and then at a later date enter the latitude and longitude. The waypoint library can be sorted and listed either numerically (default) from WPT 1 to WPT 250 or alphabetically by name. Setting this feature is explained later.

TRANSFER OF WAYPOINT DATA

It is possible to copy the waypoint library from the GPSPlus display to another or any NMEA device. This is called "downloading". There are two methods which will be explained later. The reverse process, when waypoints are copied from another GPSPlus display is called "uploading".

MARK FEATURE - INSTANT WAYPOINTS

The Mark feature allows 20 waypoints to be entered by using a single key, the MARK key. This enables pots, drift nets, and other points of interest along your present course to be instantly memorised. Pressing the MARK key enters your present position as a MARK into a reserved area of the waypoint library. These mark waypoints are automatically allocated the waypoint library names MARK01 to MARK20 and are waypoint numbers

To enter a mark simply press the

The first press will display the waypoint library, the second and further presses enter the MARKS. This can be carried out 20 times.

After all 20 mark library locations have been used the LCD will show

MARKFULL.

WPT 231

MARK

WPT 250

key twice.

If the Marks are of particular interest then it is good practice to copy them to other waypoint library locations, name them for easy identification, and then erase the original MARK. By erasing the original more MARKs can then be entered, because once the MARK library locations are full no more MARKs can be entered. These procedures are explained in this section of the handbook.

MARKs can be used to define a route. If on a passage you enter MARKs into the library, and then use them in the correct order to define a route, they can be used in reverse to lead the way home. These procedures are explained in USING ROUTES, later in this handbook.

IMPORTANT NOTE

create a route ensure that the MARK latitude and longitude is as you expect. If the MARKs have been erased and then re-entered (by pressing the MARK key) the MARK latitude and longitude will have changed and the route could be entirely different. THIS COULD ENDANGER YOU, YOUR

CREW AND YOUR VESSEL. CHECK BEFORE YOU ENGAGE THE ROUTE.

It is suggested that you use a table to record your MARK waypoints, it will help you identify and record them in the future. The following pages could be copied for this purpose or a table of your own design could be used.

: If MARK waypoints have been used to

Mark waypoints can be used exactly like any other waypoint that you have entered using the methods described in the following pages.
