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:

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.

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

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

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 WPT 231 to WPT 250.

To enter a mark simply press the MARK key twice.

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

.

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

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

: If MARK waypoints have been used to 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.

24

INTRODUCTION TO ROUTES

A "route" (sometimes called a sailplan) is simply a list of waypoints in the order that you intend to travel along them.

It is made up of "legs", where a leg is the passage from one waypoint to another. You can have up to 10 routes stored in the GPSPlus and up to 40 waypoints in each route.

A route is defined leg by leg by recalling waypoints from the waypoint library and storing them in the route. It is important to remember that a leg is a straight line drawn between two waypoints, it does not recognise any obstruction in the way such as land, shallow water, wrecks, or other vessels. When planning your route take careful note of any navigational obstructions, including high and low water marks.

It is possible to select the direction of travel along your route, either forward or reverse and then miss out a complete leg if required. This will be explained later in the

Navigation With GPSPlus section of this handbook.

VIEWING THE ROUTE LIBRARY

Turn the ▼ STEP ▲ knob. Press the ROUTE key.

When the ▼ STEP ▲ knob is turned the ten routes will be listed by number from 1 to 10 as USED or nOt USEd depending upon the current state.

If the text line of the LCD shows NULL WPT ###, (where

###

is a number from 1 to 250), it indicates that waypoint

###

has been erased from the waypoint library and therefore the route is now invalid. To overcome this either redefine the route without the waypoint, or re-enter the erased waypoint.

Below is a diagram of a simple route that will be used in this section to demonstrate the use of the GPSPlus route facilities.

NAVIGATION WITH GPS

PLUS

The NAV key is used to give navigational information from your present position to a specific waypoint, the "target" waypoint. The target waypoint could be any waypoint in the waypoint library or a waypoint that makes up one the legs of a pre-defined route.

It is necessary to select a waypoint or a route before the

GPSPlus unit can calculate the data. The target waypoint can be changed at any time so NAV information is available about any waypoint in the library.

The following navigational information is available when a target waypoint has been selected:

• Location of waypoint

•

Waypoint identity (ID)

• Bearing and distance from present position to waypoint

• Course to steer (CTS)

• Cross track error (XTE)

• Course over ground (COG)

• Speed over ground (SOG)

•

Time to go (TTG)

•

Velocity made good (VMG)

• Estimated time of arrival (ETA)

Bearings can be displayed in degrees with reference to

True or Magnetic North and distances can be displayed in

Nautical Miles, Statute Miles or Kilometres. The calculated values can be Rhumb Line or Great Circle.

The NAV key is also used to select the direction of the route, either forwards or reverse. This is the order in which www.bandgservice.co.uk

the waypoints are used.

NOTES

: If when a route is selected or when following a route the display shows the message NAV FAULT, it means that the target waypoints of the route have been deleted from the GPSPlus waypoint library. To overcome this problem either redefine the route or re-enter the deleted waypoint(s).

When following a route the GPSPlus will continue to display navigational data after the vessel has passed the final waypoint. The information will be based on the last waypoint until another waypoint or route is selected. The displayed value for cross track error (XTE) is based on an extended line of the previous track.

When the GPSPlus is used in combination with a Network

PILOT that has NMEA data being supplied to the PILOT

Display via its NMEA interface, the NAV key allows the

GPSPlus to select the PILOT NMEA data for calculation of the displayed navigational data.

IMPORTANT NOTE:

If MARK waypoints have been used to 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.

WAYPOINT ARRIVAL ALARM

The waypoint arrival alarm is always active, i.e. it CANNOT be disabled. It is used in conjunction with the auto advance function. The auto advance function is used to automatically select the next waypoint in a route or sailplan. The waypoint arrival alarm is triggered when the vessel is within a preset radius around the target waypoint. The alarm is triggered in two ways.

1.

When the vessel arrives at the target waypoint within the radius set for the auto advance function the display will sound its alarm and flash ARRIVED. Other Network units will also sound their alarms.


WAYPOINT ARRIVAL CONT...

2.

When the vessel DOES NOT arrive at the target waypoint within the set radius for auto advance, BUT crosses an imaginary line drawn through the waypoint perpendicular to the rhumb-line between waypoints, the display will sound its alarm and flash CROSSING. Other Network units will also sound their alarms.

The action taken when the alarm is activated depends on the AUTO ADVance status:

If AUTO ADVance is ON, the next waypoint in the route is used when the vessel arrives or crosses the waypoint as described above. When this occurs the alarm will sound and the display flashes for five seconds, then the next waypoint in the route will be automatically selected.

If AUTO ADVance is OFF, the next waypoint in the route is used only when a key is pressed to silence the waypoint arrival or crossing alarm. The alarm will sound and the display flash until a key is pressed, then the next waypoint in the route will be selected.

NOTE

: When steering the boat with a Network PILOT, the autopilot will not steer to the next waypoint until instructed to do so by the helmsman. This is a safety feature. Refer to the Steering to NMEA section of the PILOT owners manual.

ANCHOR ALARM

Although the name of this alarm implies use when at anchor it can be used to alert when drifting away from any specific point or waypoint.

The anchor alarm sets a circle of a specific radius around a point. The latitude and longitude of the point is determined by your position when the alarm is selected to ON. If the boat should drift OUTSIDE the predetermined radius the alarm will sound.

Press any key to silence the alarm.

In the example above, the vessel can drift anywhere in the shaded area determined by the alarm radius. When the vessel moves from point A to point B the alarm will sound.

HDOP ALARM

As in all radio navigation systems, the accuracy is affected by the geometry of the situation. Probably the most familiar examples of this today is the practice of avoiding "small crossing angles" in Loran-C or Decca lines of position

(LOP). These hyperbolic systems operate with fixed site transmitters so the angles are constant at any particular location. GPS uses moving transmitters (satellites) and therefore the geometry or crossing angles are constantly changing. In 2-dimensional GPS navigation, the lines of position are moving circles on the Earth’s surface that are, at all points, equidistant from a satellite. The effects of geometry on accuracy can be summarized in a single number, called the Horizontal Dilution of Precision (HDOP).

The accuracy obtainable from a particular set of satellites is equal to the pseudo-range measurements multiplied by the

HDOP. In order to avoid extra-ordinary errors due to short periods of very poor geometry the GPSPlus software will not use satellite constellations with an HDOP higher than twelve. The HDOP alarm allows you to be alerted when the

HDOP value becomes larger than a preset value (up to 12).

WAYPOINT ZONE ALARM

The zone alarm sets a circle of a specific radius around any waypoint. If the boat should drift INTO the predetermined radius the alarm will sound. This is very useful when attempting to remain near to a specific waypoint but without getting too close, for example, a wreck particularly good for fish. The GPSPlus display allows ten zone alarms to be set.

These could be used to create a barrier or exclusion zone as shown in the example below. Press any key to silence the alarm.

TRANSFERRING WAYPOINT DATA

Up to four GPSPlus displays can be connected into a

Network System. This allows multiple NMEA receivers to be used (remember that a single GPSPlus display allows two

NMEA receivers to be connected). To enable GPSPlus displays to co-exist on the same network most of the setups are common and the waypoint and route libraries must be identical.

When another GPSPlus display is added the data is usually transferred automatically via the system network cables.

Occasionally automatic data transfer is unsuccessful and it is necessary to manually initiate the transfer of waypoint and route library data from one unit to the other. Data transferred to other NMEA devices (not GPSPlus displays) is always initiated manually.

The copying of data, whether between GPSPlus displays or other NMEA devices, is called Uploading or Downloading depending on the direction of the data transfer.

DOWNLOADING

There are two methods of Downloading:

1.

Downloading Via B&G Network

This is when data is copied between GPSPlus displays via the B&G Network. www.bandgservice.co.uk

2. Downloading Via NMEA Interface

Waypoint data can also be transferred to other NMEA devices. This is accomplished via the GPSPlus display NMEA interface cable. The waypoints to be downloaded are selected one by one, and then transferred as a complete block of data in an NMEA sentence $IIWPL.

UPLOADING

Uploading of waypoints is accomplished via the secondary

NMEA device socket (on the rear case of the GPSPlus display) and cable directly from the position fixer selected.

All waypoints are transferred until the ENTER key is pressed to terminate uploading.

The following procedures accomplish data transfer.

SENDING 250

The number of waypoints downloading will be displayed counting down from 250.

NOTE: This method of transfer will automatically terminate when all waypoint data has been copied or when a waypoint with the same name as another already in the waypoint library is received. It is possible that the GPSPlus will display

DATABASE FAULT

and WAYPOINT

<name/number>

. This indicates that there are two different waypoints with the same number. Erase or copy one of the waypoints to another (unused) library location if this occurs.

DOWNLOADING VIA NMEA INTERFACE www.bandgservice.co.uk

When downloading in this manner it is necessary to use a special NMEA output cable (part number 610-OA-038) available from your dealer. This cable is connected to the secondary NMEA device socket of the GPSPlus display unit. The waypoints to be downloaded are selected one by one.

NMEA INTERFACING WITH GPS

PLUS

The two sockets on the rear case of the GPSPlus display are NMEA input/output connectors for position fixing instruments, radar sets, autopilots and other devices requiring NMEA interfacing. The connectors allow bidirectional data communication using the NMEA 0183 v1.5 protocol. This allows input of positional data (latitude and longitude) and other position fixer information (e.g. satellite data) into the GPSPlus display unit for displaying, and output of control sentences (including waypoint data) to a position fixer.

In a standard GPSPlus system the GPSPlus antenna/receiver unit uses the top connector, leaving the other for connection to a secondary NMEA device (e.g. a

GPS, Loran-C or Decca receiver).

DIFFERENTIAL INFORMATION

The GPSPLUS system is capable of accepting a Differential

GPS input conforming to the RTCM SC 104 V2.0 format.

Refer to the installation sheets for wiring details.

Once the GPS has obtained a fix, and the Differential receiver has locked onto the beacon, the GPSPLUS display will show the following:

The basic GPS system available to the normal user contains a deliberate inaccuracy, called Selective

Availability (SA). This limits the accuracy of the GPS position to an average of 100 metres. To improve the accuracy a system called Differential GPS (DGPS) was designed to run with the normal GPS system.

The basic principle of DGPS is that a known position

(Lighthouse, Coastguard Station, etc.) has a normal GPS receiver installed. A computer monitors the position from the

GPS and compares this to its known position. The error between the GPS position and the known position is calculated then transmitted over a conventional radio link to the vessel. The GPS on board the vessel recalculates the position taking into account the errors. A separate receiver and antenna are needed to receive the Differential beacon signal.

NOTE: The above is not a new page. The value of HDOP is replaced with GPS DIFF . www.bandgservice.co.uk

INSTALLATION OF THE DISPLAY UNIT

The display unit is supplied with a clip-in mounting bracket which allows for easy installation. Access from behind is not necessary to secure the unit in place. However, to prevent theft and permanently fix the unit in position, locking studs and thumb nuts are supplied.

SITING THE UNIT

The instrument is designed for mounting on or below deck.

A mounting position should be selected where it is:

•

Easy to read by the helmsman

•

On a smooth, flat surface

•

At least 100mm (4") from a compass

•

Protected from direct splashes of water to the rear of the display case

•

Accessible from behind for fitting locking studs if required.

TOOLS REQUIRED

•

70mm (2¾") hole cutter

• drills

•

Screwdrivers

•

Measuring tape or rule

•

Cable clips or ty-wraps.

MOUNTING THE UNIT

Use the cutting template supplied to mark the centres of the holes for the self-tapping screws, the fixing stud holes and the mounting bracket.

•

The template allows 4mm (5/32") between adjacent units for the suncover. Increase this distance if required to a maximum of 60mm (2 3/8") between units or 180mm (3

1/8") between centres. For greater distances between units extension cables are available.

•

Use a 70mm (2 3/4") diameter hole cutter for the mounting bracket hole.

•

Use a 2.9mm drill for the self-tapping holes.

•

Use a 5mm drill for the locking stud holes.

•

Secure the mounting bracket to the bulkhead with the self-tapping screws supplied.

•

Fit the rubber-sealing gasket around the mounting bracket.

•

Screw the locking studs into the back of the display head

(if required for security locking).

•

Carefully pass the cable tails through the mounting bracket hole, connect the plugs and sockets to sensor cables, power cable and other Network display units as required.

•

Clip the display head into the mounting bracket (it is a snug fit).

•

Secure the instrument with the thumb nuts supplied (if required).


INSTALLATION DATA


65

INSTALLATION OF ANTENNA UNIT

CHOOSING A LOCATION

Select a suitable site for the antenna unit with reasonable consideration of the following points:

•

As close as possible to the vessel's deck, which has a relatively unobstructed view of the horizon

•

Avoid areas where the unit could become damaged, e.g. where ropes or wires could become entangled

•

Avoid installing unit at the mast top: this location accentuates the boat’s motion

•

Avoid areas of high vibration, e.g. engine housings and radar installations

•

Not within 60cm (2ft) of other antennas, e.g. VHF, SSB

•

Above or below a radar's cone of transmission

•

Below and at least 3m (10ft) away from satellite communications equipment

Dense wood or metal structures will shield the unit from satellite signals. However, stays, masts and relatively dry sails will not interfere with reception. The unit can receive signals through glass, canvas and thin fibreglass (for example, a wheelhouse or saloon area), however it would be advisable to try such a location before permanent fixture.

MOUNTING THE ANTENNA UNIT

The GPS antenna unit may be pole mounted. The threaded socket at the base of the unit will accept a 1¼" straight thread. The GPS antenna unit only requires hand tightening on to the pole mount. Over tightening with a tool could damage the threaded socket at the base of the unit.

The pole mounting arrangement of the GPS antenna unit makes it easy for you to remove and store it in a safe and secure place when not in use. For permanent installation it is advisable to drill and pin the GPS antenna unit. This will discourage theft and prevent accidental loosening.

Alternatively the GPS antenna can be split into two parts by removing the four screws in the underside. The lower part can be discarded, leaving the GPS antenna with a flat base, which can be mounted on a cabin top or “A” frame.

If you choose this mounting option secure the GPS antenna from underneath using 4 x M3 machine screws. Care should be taken to trim overlong screws so no more than 7 turns of the thread are inside the GPS antenna.


ROUTING THE GPS ANTENNA CABLE

The GPS antenna unit is supplied with a 9 metre (30ft), shielded multicore cable. The cable should be routed to the

GPSPlus Display unit junction box and then cut to length.

For connection details refer to the installation sheet supplied with your system.

When routing the antenna cable consideration should be given to the following guidelines:

AVOID:

•

Sharp bends or kinks in the cable

•

Hot surfaces e.g. exhaust manifolds or stacks

•

Rotating or reciprocating equipment

•

Sharp or abrasive surfaces

•

Door, hatch and window jambs

•

Corrosive fluids or gases www.bandgservice.co.uk
