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. POS key - Positional Data • Position as Latitude and Longitude to three decimal places.
NAV key - Navigational Data The NAV key only gives navigational data when a waypoint or route (sailplan) has been entered and selected. • • • • • • • • Bearing and distance to waypoint; Magnetic or True bearings, Nautical or Statute miles, Rhumb-line or Great Circle calculations. Course to steer (CTS). Cross track error (XTE) with off track and direction to steer indicator. Time to go (TTG) to waypoint. Velocity made good (VMG) to waypoint. Estimated time of arrival (ETA) at waypoint.
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.
USING THE LIGHTS KEY NOTES ABOUT ENTERING DATA 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. • When a number or name is flashing the ▼ STEP ▲ knob can be turned to alter the flashing display, without the need to press any other keys. To select the value that is currently flashing, press the ENTER key.

If the ENTER key is pressed the identifiers will stop flashing, press the POS key to make them flash again. Turn the t STEP s knob to display more T.D. pairs.
INTRODUCTION TO WAYPOINTS NAMING 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. It is possible to give any waypoint a name.
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.

NET DOWNLOAD These functions are used when transferring waypoint data between other GPSPlus units and NMEA devices. They are described in the GPSPlus Interfacing section of this handbook.
INTRODUCTION TO ROUTES VIEWING THE ROUTE LIBRARY 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.
LISTING THE WAYPOINTS OF A STORED ROUTE DIAGRAM SHOWING A SIMPLE ROUTE A simple table as shown below can be very helpful when planning a route. The latitude and longitude of each waypoint could be added if required. ROUTE LEG LEG 0 LEG 1 LEG 2 FROM PPOS, present position MOORING BUOY TO MOORING BUOY FISHING Press the ROUTE key and turn the ▼ STEP ▲ knob to view the route library. The first and last waypoint name or numbers are displayed on the text line.
ROUTE PLANNING PAGE WAYPOINT TO WAYPOINT RANGE AND BEARING The GPSPlus display PLANNING PAGE allows the range and bearing to be calculated between any two, library waypoints. This facility is very useful when planning a route. 1. Press the ROUTE key until the display shows PLANNING PAGE, FROM and TO will be showing on the text display. FROM will flash. 2. Turn the ▼ STEP ▲ knob to cycle through the waypoints in the library until the desired waypoint is displayed e.g. BUOY.
DEFINING A ROUTE The route in the diagram on the previous page is used in the following example. When the waypoint library has been set to sort by name, the display will only show the first six characters of any named waypoint. If the waypoints in your library have not been named then the waypoint number will be shown e.g. W001. When sort by number is selected then the WP number is displayed. 1. Press the ROUTE key. Select a route to define using the ▼ STEP ▲ knob. 2.
5. Turn the ▼ STEP ▲ to select the next waypoint, BUOY. 6. Press the ENTER key to accept waypoint BUOY into the route. 9. Press the ENTER key again to complete the route definition. 10. Press the ROUTE key, the display will now show ROUTE 1, USED, and the start and end waypoints. 7. Turn the ▼ STEP ▲ to select the next waypoint, FISHIN. This waypoint is the last waypoint in this route. 8. Press the ENTER to select FISHIN into the route. END will flash.
EDITING A STORED ROUTE Any stored route in the route library can be edited. Waypoints can be inserted into or deleted from any leg of your defined route, or simply added on to the end. There is also facility to delete the entire route from the route library. If all the waypoints are deleted the route will be listed as nOt USEd when the route library is viewed. To edit a leg of a route proceed as follows: INSERTING AND DELETING WAYPOINTS IN A ROUTE 1. Press the ROUTE key until ROUTE # is displayed.
OTHER ROUTE SETUPS The SETUP key has another function beyond the Route Erase function. This function, ROUTE DOWNLOAD, is described in the GPSPlus Interfacing section of this handbook.
NAVIGATION WITH GPSPLUS 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.
SELECTING OR CHANGING THE TARGET WAYPOINT OR ROUTE 1. Press the NAV key. If the unit is not already NAVing, nO PLAn will be displayed. The text display will invite you to press SETUP. 2. Press the SETUP key, the display will flash either NO PLAN, or one of the displays shown in 3. 3. Use the ▼ STEP ▲ knob to select the waypoint or the route to be used for navigation.
DISPLAYING THE NAV PAGES Press the NAV key to display the following pages of navigational data: PAGE 1 ROUTE SELECTED - USING ROUTE # When a route has been selected from the route library the display will show which route is selected, the direction of travel along the route and the current leg. SELECTED NAV DATA One of three different pages will be displayed depending upon whether a waypoint, route or Pilot NMEA data is being used for NAV functions.
PAGE 2 BEARING AND DISTANCE Bearing (brG) and Distance from present position to the target waypoint. Bearing is displayed in degrees Magnetic (M) and distance is displayed in nautical miles (nM) by default. PAGE 3 BEARING, DISTANCE, XTE, SOG AND COG Bearing to target waypoint. Cross track error, alternating with direction to steer. Speed Over Ground and Course Over Ground, alternating with Distance to target waypoint. PAGE 4 BEARING, XTE, TTG AND VMG Bearing to target waypoint.
PAGE 6 ESTIMATED TIME OF ARRIVAL WAYPOINT SELECTED EtA POINT Estimated time of arrival at the target waypoint in hours and minutes. The date, month and year are displayed on the bottom line. PAGE 7 LATITUDE AND LONGITUDE OF TARGET Latitude and Longitude of target waypoint. The target waypoint name or number is shown on the text display. ROUTE SELECTED EtA END Estimated time of arrival at the last waypoint of the route in hours and minutes. The date, month and year are displayed on the bottom line.
CHANGING THE CURRENT LEG OF A ROUTE The GPSPlus allows any leg of the selected route to be missed or skipped over so that the route can be changed without inserting or deleting any waypoints. Once a route has been selected proceed as follows: 1. Press the NAV key. The display will show the last NAV page displayed. 2. Press the SETUP key three times. The display will show the current leg number of the selected route, e.g. CURNT LEG 0. 3. Press the ENTER key, the leg number will flash.
INTRODUCTION TO SETUPS ON THE GPSPLUS The GPSPlus has many parameters that can be set if the user wishes, some of these are alarms. The sequence for adjusting or setting these parameters and alarms is similar in every case, only the displayed information is different. The SETUPs are arranged in a continuous list that you can cycle through using the SETUP key. For a full description of each SETUP with its selectable parameters please refer to the table at the end of this section.
SELECTING THE RECEIVER INPUT TYPE WAYPOINT ARRIVAL ALARM If your GPSPlus system has a LORAN-C or DECCA receiver, connected to the second receiver socket on the rear of the unit, this can be selected to give positional information. All of the features and functions of the GPSPlus can be used with any of the receivers. This allows you to select a different position fixer if one becomes unreliable, or to compare accuracy of position. The waypoint arrival alarm is always active, i.e. it CANNOT be disabled.
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.
WAYPOINT ARRIVAL CONT... ANCHOR ALARM 3. Press the ENTER key, OFF will now flash. 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. 4. Use the ▼ STEP ▲ knob to select ON or OFF. NOTE: The AUTO ADV feature is factory set to OFF. SETTING AUTO ADVance rADIUS The anchor alarm sets a circle of a specific radius around a point.
SETTING THE ANCHOR ALARM HDOP ALARM 1. Press the POS key. 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.
GOOD SATELLITE GEOMETRY - LOW HDOP (<12) SETTING THE HDOP ALARM 1. Press the POS key. 2. Press the SETUP key until HDOP ALrM is displayed. 3. Press the ENTER key, the display will flash the current HDOP alarm limit. 4. Use the ▼ STEP ▲ knob to alter the limit in the range 0.1 to 12.0. NOTE: The value is factory set to 4.0. 5. Press the ENTER key to memorise your setting. The display will now flash the current alarm state. BAD SATELLITE GEOMETRY - HIGH HDOP (>12) 6.
CROSS TRACK ALARM The Cross Track Error Alarm is triggered when the vessel strays to the left or right of the course line drawn between the last waypoint and the next waypoint in a route by more than a preset distance, in other words, if the Cross Track Error (XTE) value is larger than the value set. SETTING THE CROSS TRACK ERROR (XTE) ALARM 1. Press the POS key. 2. Press the SETUP key until CrOSS trK is displayed. SEtUP CrOSS trK OFF 3.
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.
NETWORK SYSTEM ALARMS NETWORK PILOT ALARM DISPLAYS The GPSPlus display has an internal buzzer that will sound when an alarm condition is met on a Network unit that has alarm functions: Network DEPTH and Network QUAD for depth alarms and Network PILOT for Watch Alarm and Off Course alarms. The unit will also display which alarm is activated. WATCH ALARM To silence the internal alarm and return the display to normal operation press any of the keys.
SETTING THE CHART DATUM SETTING A USER DATUM The chart datum can be obtained from the navigational chart you are using. This is a user entered latitude and longitude offset obtained from some charts. 1. Press the POS key. NOTE: Before USER DATUM can be used USER ENTERED must be selected as DATUM, see previous section. 2. Press the SETUP key until dAtUM is displayed. 1. Press the POS key. SEtUP dAtUM 2.

All distances are displayed in the units selected, either NM Nautical Miles, M - Statute Miles or K - Kilometres. The default setting is NM - Nautical Miles. 1. Press the POS key. 1. Press the POS key. 2. Press the SETUP key until MAG VAR is displayed. The current mode will also be displayed.
COG AND SOG DAMPING CALCULATION METHOD FOR BEARINGS This is the damping factor applied to Speed and Course Over the Ground. When set to AUTO more damping is applied when SOG is low, to prevent display jitter. This setup is the method used by the unit to calculate bearing and distance in NAV mode. The unit can be set to use either Rhumb Line or Great Circle. Select the one most suitable for your navigational needs. 1. Press the POS key. 1. Press the POS key. 2.
CHANGING THE DISPLAY LANGUAGE Changes the display language format from English to French. All displays will be in the language selected. By default the setting is English. 1. Press the POS key. 2. Press the SETUP key until LANGUAGE is displayed. The current setting will also be displayed. SEtUP LANGUAGE ENGLISH 3. Press the ENTER key, the display will now flash. 4. Use the ▼ STEP ▲ knob to change the setting. 5. Press the ENTER key to memorise the setting.
MULTIPLE GPSPLUS DISPLAY INSTALLATIONS Installations with two or more GPSplus displays fitted must select which GPSplus display will receive the data. When the GPSplus displays and GPS antenna are powered up the display should show the following: If the above is not shown then press the SETUP key until the following is displayed: Press the ENTER key, the display will now show nOt USEd. Turn the ▼ STEP ▲ knob. If the GPS has not yet locked onto the position then nOt USEd will remain.
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. 2. Downloading Via NMEA Interface Waypoint data can also be transferred to other NMEA devices.
When downloading in this manner the waypoints are transferred via the B&G Network interconnecting cables as Network data. The waypoints are downloaded as one complete block of data. 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. 1. Press the WPT/MOB key. 1.
UPLOADING WAYPOINTS DOWNLOADING ROUTE DATA Uploading of waypoints is accomplished via the secondary NMEA device socket and cable directly from the position fixer selected. All waypoints are transferred until the ENTER key is pressed to terminate uploading. When multiple GPSPlus displays are used it may be necessary to copy the route data (that is, all the waypoint data stored in a route), between displays.
NMEA INTERFACING WITH GPSPLUS 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.
NMEA OUTPUT NMEA OUTPUT SENTENCE LIST The GPSPlus display software provides NMEA output from both of the receiver connection sockets. The following is a list of all the NMEA output sentences available from the GPSPlus display unit including the initial setting. The SETUP key allows selection of each sentence as ON or OFF, allowing custom interfacing as required by the end user. It is necessary to select the required NMEA output sentences as ON (transmitted) or OFF (not transmitted).
GPSPLUS 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).
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.
INSTALLATION DATA 65
INSTALLATION OF ANTENNA UNIT CHOOSING A LOCATION MOUNTING THE ANTENNA UNIT 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.
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.
