INTRODUCTIONThe AccuNav Sport™ is a high quality, big screen hand-held GPS receiver with performance that is second tonone in its class. Using menu features and raised soft-key operation, the AccuNav Sport™ is also one of theeasiest to use products that Eagle has ever built. Thewide screen shows the navigation and plotter screenswith high resolution and detail. The display and key-board are also lighted for night operation.

The electronics are sealed inside the welded, dry nitro-gen filled case. This both waterproofs the unit and helpsprevent fogging on the display. The battery compart-ment has "O" ring seals to keep water penetration to aminimum.

Please read this manual carefully before using yourAccuNav Sport™.

GPS - HOW IT WORKSThe Global Positioning System (GPS) is perhaps thebest approach to navigation that has ever been devised.Conceived by the Department of Defense (DOD) andthe United States military, the GPS system is an answerto their needs of 24 hour global positioning, 365 days ayear.

Basically, the system works by using a constellation ofsatellites orbiting Earth 11,000 miles in space. There willbe 24 satellites in orbit when the system is fully opera-tional. When all satellites are in place, at least four ofthem will be in view nearly anywhere on Earth twenty-four hours a day. The GPS receiver requires at leastthree satellites to give a “2D” fix. (A 2D fix is your positionin latitude/longitude. A 3D fix is your latitude/longitudeplus altitude.) When it locks on to at least four satellites,it displays a 3D fix. It takes three satellites to determine position.

more precise system is coding. In other words, the datacoming from the satellites is encrypted. Civilian GPSreceivers use “C/A Code.” Its accuracy is intentionallyworse than the military’s “P Code.” In this manner,civilian users worldwide can benefit from excellent po-sition fixes. Meanwhile, the military keeps the mostaccurate system away from potential enemies. Theo-retically, C/A code can give accurate position fixes up to15 meters. This is more than adequate for most people.

However (as of this writing), the military isn’t satisfiedwith C/A’s potential accuracy in the hands of the world.So, it’s degrading it further with “Selective Availability” orSA. This is small, random errors intentionally added tothe system so your accuracy will typically be within 100meters. Of course, accuracy also depends on the angleof the satellite above the horizon, signal-to-noise ratio,the number of satellites tracked at one time (the more

As the receiver locks on to each satellite, it calculatesthe distance from the satellite by measuring the lengthof time it takes the radio signal to reach it. Each satellitehas an extremely accurate clock that tells the receiverwhen the radio transmission started. The receiver com-pares that time against its own clock, thus it knows howlong it took the radio signal (travelling at the speed oflight!) to reach it. If you know time and speed, then youcan calculate distance. Once you have this from threesatellites, then the receiver can determine your posi-tion.

ACCURACYYou may have heard tales of extraordinary accuracyfrom GPS receivers. The DOD requires accuracy of 10to 15 meters from the satellite system. However, onlythe military gets this precision. The way the militarykeeps us and other unauthorized people from using the

the better), and other factors. The smallest ranges onthe plotter may not be usable if the SA is high. Thepresent position symbol can move off the screen evenwhile you’re sitting still.

Don’t let this discourage you. GPS by nature has muchfaster updates than other systems (such as Loran), andtypically is much easier to use. Accuracy, even with SAon is still better than most other navigation systems.You’ve purchased one of the finest navigation instru-ments on the market today. We hope you’ll enjoy it formany years to come.

The EAGLE™ GPS ReceiverThe Rockwell GPS engine is currently used in all Eagle™GPS receivers. It’s small, rugged, and fast. The fivechannel design lets it track all satellites in view. It sendsposition information to the AccuNav Sport™ from onceevery second to once every five seconds (user select-able.) By incorporating Rockwell’s GPS receiver tech-nology with Eagle’s state-of-the-art design and manu-facturing capabilities, Eagle brings to the consumer oneof the most advanced GPS navigation systems avail-able in the world.

ANTI-SKIDThe AccuNav Sport™ has a recess molded into theback of the case and one-half of a plastic fastenerattached to the recess. When used with the other half ofthe fastener, it keeps the unit from sliding on a levelsurface such as a dashboard.

To use the anti-skid material, first remove the fastenerfrom the literature pack supplied with the AccuNavSport™. Select the location for this fastener and peel theplastic backing from this half and press it onto themounting surface. Align this patch with the one on theAccuNav Sport™, then press them together. It will holdthe unit under mild vibration, keeping it from sliding.

NOTE: The adhesive anti-skid patch is not designed tohold the AccuNav Sport™ on a vertical or overheadsurface. It is only to be used to keep the unit from slidingon a flat, horizontal surface.

EXTERNAL POWERThe AccuNav Sport™ uses six AA batteries or (usingthe optional CA-1 adapter cable) 6 to 35 volts DC froman external power source. To use external power (suchas a car's cigarette lighter), simply push the CA-1's pluginto the small connector on the side of the AccuNavSport™. Plug the other end of the CA-1 into the vehicle'scigarette lighter, and the AccuNav Sport is ready for use.(Note: A rubber plug comes with the AccuNav Sport tocover the external power jack on the side of the unitwhen it's not in use.)

BATTERY INSTALLATIONThe AccuNav Sport™ requires six AA batteries.We recommend DuraCell™ alkaline batteries, butother brands will work. You can use lithium batter-ies which will last longer than alkaline batteries.Rechargeable ni-cad batteries will also work in theAccuNav Sport™, however they won't last as longas alkalines. Do Not use heavy-duty batteries orany battery other than the ones listed above. Do notmix different types of batteries. (e.g. ni-cads andalkalines)To install the batteries, first turn the AccuNavSport™ so that it is facing you. Now grasp thebottom part of the case and push it to the right untilit comes completely off the unit as shown at right.The bottom part of the AccuNav Sport™ housesthe battery pack.

Now push the battery pack out the bottom of the batterycover as shown at right. Install the batteries with thenegative end (-) toward the springs. The positive end (+)should be firmly against the metal plate. When all sixbatteries are installed in the battery pack, slide it into thebattery cover.

If the battery holder sticks when sliding it into the batterycover, apply a thin film of petroleum jelly to the "O" ringson the battery holder.

Slide the battery pack onto the unit and the AccuNavSport is now ready for use.

Notice!There is a tab on the top of the battery holder thataligns with a slot on the top of the battery cover. Makecertain the tab is aligned properly! Otherwise thebattery holder won't slide all the way into the coverand the battery cover won't slide onto the unit.

Vari-Power™ Battery Saver FeatureThe AccuNav Sport™ has a five-level power savingfeature that can extend the life of the batteries consid-erably. It does this by changing the update rate of theGPS receiver inside the unit. When you first turn theAccuNav Sport on, the update rate is once per second.In other words, the GPS receiver calculates and sendsyour position to the display once per second. You canlengthen this time to as little as once every five seconds.The longer the update rate, the less power is drawn fromthe batteries. For example, less power is drawn from thebatteries when the unit is in the five second update ratethan the one second rate. There can be exceptions tothis rule, however. Whenever the AccuNav Sport istrying to lock onto the satellites, it automatically goesinto the one second update mode. If you are walking ina wooded area with the unit set on the five secondupdate mode, the unit may lose its lock on the satellites

due to the trees overhead. When this happens, the unitautomatically goes into the one second update modeuntil it locks onto the satellites. Then it returns to the fivesecond mode. If you are walking through heavy treecoverage with only occasional gaps in the trees, the unitmay remain in the one second update mode continu-ously. Typically, however, the AccuNav Sport™ willconsume less power with higher update rates undernormal conditions.

Although there is no indicator on the navigation orplotter displays to show which update mode you are in,watching the clock can show you the current mode. Alldisplays, including the clock are updated at the sametime. If you have it set for a three second update, thenthe clock will "freeze" for three seconds, then show thecorrect time, then "freeze" for three seconds and so on.

Also note that the AccuNav Sport™ automatically goesinto the one second update rate whenever externalpower is applied to the unit. For example, if the CA-1cigarette lighter adapter cable is plugged into theAccuNav Sport and the other end is plugged into yourcar's cigarette lighter, then the update rate will automati-cally switch to theone second update.

To adjust the updaterate, turn the unit onby pressing the ONkey. Next, press theMENU key, then theF5 key which corre-sponds to the"CHANGE GPSSETTINGS" label.

Now press the right arrow key to see the second menuscreen. The screen shown on the previous page ap-pears. Press the F1 key which corresponds to the"POWER SAVING SETUP" label. A screen similar to theone below appears.

The update rate cur-rently in use showsat the bottom of thescreen. This one iscurrently using theone second update.To change it, simplypress the key corre-sponding to the de-sired update rate.For example, tochange to a four sec-

ond rate, press the F4 key. The update rate changes toonce every four seconds and the display at the bottomof the screen will show "CURRENTLY USING: 4 SEC."To exit this screen, press the CLR key.

LOW BATTERY INDICATORWhen the battery voltage reaches six volts, a lowbattery message appears in the lower left corner of thedisplay. If you are using alkaline batteries, and the unitis in the one second update mode, then you will haveapproximately 15 minutes or less until the unit auto-matically shuts off. If you have the unit in the fivesecond update mode, you will have approximately 45minutes or less until the unit shuts off.

Note:In cold weather, keep a spare set of batteries in a warmplace, such as a shirt pocket. Warm batteries lastconsiderably longer than cold ones.

ANTENNAThe AccuNav Sport™ has a removable antenna thatfolds over the display when the unit is not in use. To openthe antenna, simply lift on an edge of the antenna andraise it to the desired angle.

Two thumbscrews on the antenna's hinge let you adjustthe tension on the antenna. This helps keep the antennain the desired position. The thumbscrews work in oppo-site directions. To tighten the right thumbscrew, rotate itaway from the display. To tighten the left thumbscrew,rotate it toward the display.

Caution - Always make certain the left thumbwheel istight when using the AccuNav Sport™. The connectorfor the antenna is inside the left thumbwheel. If it isn'ttight, a poor connection may occur. This can prevent theAccuNav Sport™ from operating properly, if at all.

13

To remove the antenna, simply loosen the thumbwheelsuntil they won't turn. Carefully remove the antenna fromthe unit by pulling it straight out. If you feel any resis-tance, make certain the thumbwheels are at the end oftheir travel. Don't force any parts.

Once you remove the antenna, you can see it's connec-tor inside the left-hand thumbwheel. When reinstallingthe antenna, align the left side of the antenna first, thenthread left thumbwheel until it engages the connector.This will require two full turns of the thumbwheel. Afteryou've accomplished this, thread the right side of theantenna by rotating the right thumbwheel. Remember torotate the right thumbwheel in the opposite directionfrom the left.

Adjust thumbwheels until the desired tension is achieved.Caution - Do not overtighten the thumbwheels.

14

ANTENNA ANGLEWhen using the AccuNav Sport™, try to make certainthe antenna is parallel with the ground, or nearly so asshown at right. Since the signals from the satellites are"line of sight", a flat antenna gives you a better chanceof being able to receive the signals from all of theavailable satellites.

Also, trees, buildings, carports (even your body), canblock the signals from the satellites. When using thisunit in heavy brush or timber, remember that it may losetrack on one or all of the satellites until you move into aclearing.

We have successfully used the AccuNav Sport™ incars and trucks since the satellite's signal passes throughglass. However, antenna placement can make a differ-ence in receiving the signals or not.

MENUSMost of the AccuNav Sport's™ features are found onpages of "menus". Pressing the MENU key lets you viewthe menus. This unit has four basic displays. They are:Windows, Position, Steering, and Plotter. When youpress the MENU key, different menus appear depend-ing on the displaymode the unit is in.(Except the plotterand steering displaysshare the samemenus.) In otherwords, if you press theMENU key while theposition screen isshowing, the menushown at right ap-pears. However, if you

press the menu key while the plotter is displayed, adifferent menu appears as shown below. This gives youthe features specific to each display without having tosearch through many pages of menus.

Unless otherwise specified, all menu examples used inthis manual are ac-cessed while the po-sition or steeringscreen is showing.

More information onmenus are shown inthe back of thismanual.

Initialization - Power OnIn order for the AccuNav Sport™ to lock onto thesatellites, it must first find them. If you simply turn the uniton and wait, the unit will find the satellites by itself in 15minutes or less. This is called “Cold Start.” If you let it findthe satellites, the time display will probably be wrong,since it will be showing UTC time which is the time atGreenwich, England. However, all other navigationdisplays, including the position display will be correct.(You can set the time display to your local time.) Tospeed up the satellite acquisition process, you caninitialize the AccuNav Sport™ or “tell it where it is” thefirst time it’s turned on. This initialization process isusually done only once and requires the following data:

1. Approximate present position in latitude/longitude2. Approximate elevation above sea level (altitude)3. Today’s date and time

The unit usually only takes a few minutes or less to findthe satellites once it’s been initialized by the user.

After the batteries are installed and the antenna isopened, press the ON key, then press the MENU key.Now press the key next to the “CHANGE GPS SET-TINGS” label. Finally,press the key next tothe “SET LAT, LON,ALT, TIME, DATE”label. The screenshown at right ap-pears.

20

This is the GPS setup screen. The settings now in useare shown at the top of the display. If you’re using theunit for the first time, these settings are probably wrongfor your position and time. To change any of the num-bers on this display, first press an up or down arrow keyto move the black box to the desired label. For example,to change the localtime, press the downarrow key until theblack box is on the“LOCAL TIME”,press the F6 key,then enter your timeusing the numberedkeys.

CHANGE POSITIONTo change the position shown on the AccuNav Sport'sdisplay, first determine your approximate position. Usea chart or call your local airport to determine yourposition if you don’t know it. The latitude/longitude thatyou enter doesn’t have to be extremely accurate. Typi-cally, if you enter a position within a few degrees of yourpresent position, the AccuNav Sport™ should quicklyfind your actual latitude/longitude. To change yourpresent position, first move the black box to the LATI-TUDE display, then press the F6 key to change it. Thescreen shown at right appears. Use the down arrow keyto change the “N” to “S”, if necessary. Next, simply enteryour present latitude using the numbered keys. Noticethat the position entered is in degrees, minutes, andhundredths of a minute. (Not seconds!) If you make amistake, press the left or right arrow keys to move to thenumber in the latitude that needs changing. After the

21

latitude has been entered, press the ENT key.

Now move the black box to the LONGITUDE display.Enter your present longitude within a degree. Use the upor down arrow keys to switch to east or west longitude,if necessary. Now enter the longitude using the num-bered keys. Be cer-tain to enter a zero“0” as the first num-ber in the longitude ifit’s less than 100 de-grees! After you’veentered the last num-ber, press the ENTkey.

CHANGE ALTITUDETo enter your present altitude, move the black box to theALTITUDE display, then press the F6 key. The AccuNavSport™ needs to know your elevation above sea level.(Not your height above the ground.) Again, an approxi-mation within a few thousand feet is usually sufficient.Use the numbered keys to enter your altitude data.Press the up arrow key if your altitude is below sea level.For example, suppose you’re in Death Valley and thespot you’re standing in is 35 feet below sea level. Youwould need to enter the numbers “35”, then press the uparrow key to change it to -35 feet. Press the ENT keywhen you’re done.

CHANGE TIMETo change the local time (the time at your position),move the black box to the LOCAL TIME display, thenpress the F6 key. The screen shown at right appears.

22

Use the number keys to enter the time. Press the uparrow key to change the time from AM to PM or the downarrow key to change from PM to AM. Press the ENT keywhen you’re finished.

CHANGE DATETo enter today’s date,move the black boxto the LOCAL DATEdisplay, then pressthe F6 key. Thescreen shown on thenext page appears.Enter the date usingthe numbered keys.When you’re finished,press the ENT key.

The numbers at the top of the screen should be correct.If they aren’t, press the key next to the label that youneed to change. If everything is correct, press the keynext to the “EXIT” label. The unit will switch to theposition screen and start searching for the satellitescurrently in view. The AccuNav Sport™ should find thesatellites and show aposition in a few min-utes.

23

COLD STARTWhen the AccuNav Sport™ is turned on for the first time“out of the box”, it automatically sends a “cold start”message to the GPS receiver. You can also send a coldstart message to the receiver at any time.

If the unit can’t lock on to the satellites using the datayou’ve given it, or if it has trouble finding the satellites,perhaps it is using the wrong data. This can happen ifyou’ve entered the wrong data by accident. For ex-ample, giving it east longitude instead of west. Or ifyou’ve moved a long distance with the unit turned off.The unit will automatically issue a cold start to it'sinternal GPS receiver, however, you can send a coldstart at any time.

To send a cold start message to the receiver, press theMENU key. Now press the key next to the “CHANGE

GPS SETTINGS” label. Finally, press the key next to the“GPS “COLD” START” label. The unit will begin a coldstart technique to find the available satellites. It shouldlock on to them in 15 minutes or less. Remember, whenit does, your local time and possibly date display willprobably be wrong. Use the method shown previously toset the time and dateto their proper localsettings. Once this isdone, an internalclock will keep thecorrect time, evenwhen the unit is turnedoff. The GPS systemupdates this clockwhen the unit islocked on to the sat-ellites.

24

DO NOT NAVIGATE WITH THIS UNIT UNTIL YOUHAVE FOUND THE REASON THE UNIT HAS LOSTTHE SATELLITES!

Each of the following screens (except the satelliteinformation screen) is available by pressing its key.(Press the MENU key,then press the keynext to the "SatelliteInformation" to seethe satellite informa-tion screen. A detaileddescription of eachscreen follows.

POSITION/NAVIGATION DISPLAYSThe AccuNav Sport™ has a position screen, plotter,steering indicator, and a satellite information screen.These displays were designed to show the most impor-tant data. However, using the Windows feature, manymore screens are available that show navigation infor-mation in various arrangements. See the Windowssection for more detail.

IMPORTANT! If the data shown in digital numbers on any screen onthis unit is flashing, then it means that data is invalid. DONOT RELY ON THAT DATA IF IT IS FLASHING! Forexample, if the position display is flashing, then the unithas lost the satellites and hasn’t reacquired them. Theposition that is flashing is your last known position, notyour present position!

POSITION SCREEN

25

SATELLITE INFORMATION SCREENThe satellite information screen shows technical dataabout each satellite in view. The AccuNav Sport™ hasa five parallel channel GPS receiver. Data on eachchannel is shown at the top of the display. The channelsare numbered one through five on the left side of thescreen. Every satellite in the constellation has a numberassigned to it, called the PRN. The PRN is the firstnumber in the channel’s row. TRK stands for “track.” Ifit's tracking the satellite, then a “T” is placed in thiscolumn. If the AccuNav Sport™ is searching for thesatellite, then a “S” appears. ELV is the elevation(height) of the satellite above the horizon from yourposition. AZM is the azimuth or direction of the satellitefrom your position. For example, if the azimuth of asatellite is 180 degrees, then it is due south of yourposition. SNR is the signal-to-noise ratio. This tells youhow strong the satellite’s signal is. The higher the SNR

number, the better. Typical good SNR numbers arebetween 30 and 50.

The satellites that are visible in the sky from yourposition are shown in the lower right corner of the screenunder the “VISIBLE SATS”.In the lower left cor-ner of the screen arethe DOPS displays.These show you the“Dilution Of Precision”(DOP) for the horizon-tal (HDOP), geomet-ric (GDOP), position(PDOP), time(TDOP), and vertical(VDOP). The GDOPis the combination

26

value of HDOP, VDOP, and TDOP. The smaller theGDOP’s number is, the better. The GPS receiver se-lects satellites based on GDOP, therefore it always triesto use satellites that have good DOP values. Thesedepend on the azimuth and elevation of the satellite,and any ground based obstructions.

Remember, the smaller the number - the better on all ofthe DOPs.

POSITION SCREENThe position screen automatically appears after theAccuNav Sport™ is initialized or you can view thisscreen at any time by pressing the POS key. Theposition display shows your present position (POSI-TION), bearing (BRG), course over ground (COG), localtime, cross track error (XTE), time to go to waypoint(TTG), and waypoint name (WPT NAME).

Your present position shows near the top of the screenin latitude/longitude coordinates. This is shown in de-grees, minutes, and thousandths of a minute. For ex-ample, on this page, the present position is 36 degrees,8.987 minutes north latitude and 95 degrees, 50.553minutes west longitude. Below the present position onthe left side is theBearing to Waypoint(BRG) display. This isexpressed in degreestrue or magnetic, de-pending on the modethe AccuNav Sport™is in. To the right ofthe Bearing is theCourse Over Ground(COG) display. At thebottom of the screen

27

are the Local Time and Cross Track Error Displays.Please note that you must recall a waypoint to use theBearing and Cross Track Error displays.

STEERING SCREENThe steering screen shows a pictorial view of yourvehicle and course travelled. This is called a CourseDeviation Indicator or CDI. It also shows Distance ToGo (DTG), Speed Over Ground (SOG), Bearing toWaypoint (BRG), and Course Over Ground (COG).Press the STEER key to view this screen.

Your present position is shown by the arrow. The arrowshows the direction your vehicle is heading relative tothe waypoint. In theory, if you steer with the arrowalways pointing towards the waypoint, then you willarrive at the waypoint. The solid line extending from thearrow is your track or path you’ve taken. To travel

directly to a waypoint, try to keep the arrow on the centerline. The waypoint is depicted by a box at the top of theCDI display. As you approach the waypoint, the arrowand the box will move closer together. If you travel pastthe waypoint, the waypoint’s box will move to the bottomof the display.

The numbers on thetop left side of thescreen are distancemarkers, showing theremaining distance tothe recalled waypoint.If the numbers have ablack box surround-ing them, then the dis-tance markers areshowing the distance

PAST the waypoint. In other words, if the numbers aresurrounded by a black box, then you have passed thewaypoint and need to turn around.

The numbers immediately below the CDI are the CDIrange limits in miles. This gives you an idea of how faroff course you are. For example, if the arrow is halfwaybetween the course line and the outside left line and theCDI range is 0.5 miles, then your cross track error is tothe left 0.25 miles. The CDI range is the same as the CDIalarm setting. See the section on GPS alarms to changethe CDI range.

Using the digital displays at the bottom of the screenwith the graphical display at the top lets you accuratelysteer to a waypoint.

CUSTOMIZE SCREENSThe digital displays on the bottom half of the positionand steering screens, plus all of the digital displays onthe plotter screen can be changed as desired. To showhow this is done, we’ll use the position screen as anexample.

PLOTTERThe plotter lets you see your course and direction oftravel on the screen. If you’ve recalled a waypoint, theplotter shows your starting location, present position,and destination. However, you do not have to recall awaypoint to use theplotter.

The plotter also canshow grid lines on thedisplay. These gridlines show latitudeand longitude linesthat can help you seeyour position or thelocation of other ob-jects.

31

To use the plotter, simply press the PLOT key. A screensimilar to the one at the bottom of the previous pageappears.

The flashing cross is your present position. The solidline is your current track, or path you have just traveled.The large square is a compass rose marked with North,South, East, and West. The square’s height and widthshows at the bottom of the screen. This is the distancefrom one side to the other and from the top to the bottom.Your present position is shown at the top of the screen.

If your present position starts to move outside thesquare, the AccuNav Sport™ clears the display, thenredraws your present position closer to the center of thescreen. Your present position will always be displayedon the plotter. To clear the plotter screen, see the PlotterMenus section.

On the left side of the screen are the Distance To Go(DTG), Speed Over Ground (SOG), Bearing (BRG), andCourse Over Ground (COG) digital displays. All of thesedisplays are only used when a waypoint is recalled,except COG and ALT which are always active. Thesedisplays also can be customized. See the Plotter Menussection for more detail.

PLOTTER CURSORThe plotter cursor can help you determine the latitude/longitude of a waypoint or event marker. To use it, pressthe up or down arrow key while the plotter is displayed.A screen similar to the one on the next page appears.Two new lines appear on the screen. These are theplotter cursor lines. Also, the present position display atthe top of the screen switches to show the latitude/longitude position of the plotter cursor - not your presentposition. The distance and bearing from your present

32

position to the cursor position show in the bottom leftcorner of the display. Use the arrow keys to move thecursor lines anywhere on the plotter. To erase thecursor lines, press the CLEAR key. This will switch thedisplay at the top of the screen back to your presentposition and erase the distance and bearing displays atthe bottom of thescreen.

PLOTTING WITH A WAYPOINTUsing the plotter with a recalled waypoint or route is aneasy way to see the distance and direction you trav-elled. It also simplifies navigation. To use the plotter inthis manner, first recall a waypoint or start a route. (Seethe Waypoint Recall section for more information.) Thenpress the PLOT key.A screen similar tothe one at right ap-pears.

The circle with the “S”is your starting loca-tion. This was yourposition when yourecalled the way-point. The flashingcircle with a cross is

33

your present position. The “flag” with a number inside isthe destination (recalled waypoint). The number insidethe flag is the recalled waypoint number. In this ex-ample, waypoint number 1 is the destination. The dottedline is the shortest, most direct course from the startingpoint to the destination. Follow this line to get to thewaypoint.

An arrival alarm can be set to sound a tone when youcome within a preset distance to the destination. See thesection on alarms for more information about the arrivalalarm.

PLOTTER MENUSPressing the MENU key while the plotter is showinggives you a new set of menus that relate only to theplotter. There are two plotter menus. The first menu isshown at right.

If you turnthe unit off while it is navigating, the next time it's turnedon it will still navigate to the previous waypoint. If youwere navigating in a route when you turned the AccuNav

Sport™ off, the next time you turn it on, the unit willremember where you were in the route at the time it wasturned off and resume navigation to the same waypointin the route.

51

ROUTESA route gives you the ability to navigate to severalwaypoints without having to reprogram the unit afterarriving at each one. A route consists of two or morewaypoints. When you start on a route, the AccuNavSport™ shows navigation information to the first way-point in the route. When you reach the first waypoint,(signalled by the Arrival Alarm), the AccuNav Sport™automatically sequences to the next waypoint. Naviga-tion information is shown to this waypoint and theprocess repeats. When you reach the last waypoint in aroute, the arrival alarm sounds until you turn it off. At thispoint you should use the "Cancel Navigation" feature tostop the AccuNav Sport™ from showing navigation datato the last waypoint in the route. Otherwise, it willcontinue to navigate to that waypoint, even if it's turnedoff and on again.

There are four steps required to create and follow aroute. First, you must create and name the route. Next,select the waypoints used in the route. Then determinethe starting waypoint. Next, tell the unit to follow theroute. Finally, the unit will ask you if you wish to run theroute forward or backward. After these steps are com-pleted, the AccuNav Sport™ will start showing naviga-tion data to the first waypoint on the route.

NOTE: The plotter shows all of the waypoints on arecalled route connected by a dotted line.

52

CREATING A ROUTETo create a route, first press the RTE key . The screenshown at right appears. Now press the F1 (SAVE/EDITROUTE) key. The screen shown below right appears.

Use the keys on both sides of the screen to enter thewaypoint name. Forexample, to name aroute “RED ROCK”,press the F6 key re-peatedly until the let-ter “R” appears in thewindow. Next, pressthe right arrow key tomove the black boxto the next letter posi-tion. Now press theF2 key until the letter

53

“E” appears on thescreen. Repeat thisprocess until the en-tire name has beenwritten on the screen.Now press the ENTkey. The AccuNavSport™ returns to theroute menu. You cannow enter the way-points used in theroute.

Waypoint SelectionIf you’ve named a route, the black box should be on the“0” at the top of the waypoint list on this screen as shownon the screen at right. If not, move the black box to the“0” using the up or down arrow keys. Now press the ENT

key. The screen shown on the next page appears. Nowpress the numbered key of the waypoint you wish to goto first in the route. For example, if you want waypointnumber 2 to be first, press the 2 key. If you’ve named thewaypoint, it shows in the blank space to the right of thewaypoint number.Next, press the ENTkey. The AccuNavSport™ reverts to themenu shown at right.

The cursor shouldnow be on the sec-ond waypoint line.Again, press the ENTkey and enter thewaypoint number forthe second waypoint

54

in the route. Continueentering the way-points until all of thewaypoints have beenentered for the routeas shown on thescreen at the far rightside of this page.Then press the F3key. This saves yourroute in memory.

IMPORTANT!You must select waypoints in the order they are to beused in the route. In other words, suppose you want aroute that consists of waypoint numbers 1, 2, and 3.However, you wish to travel to 2 first, then 1, and finally

3. In this case, youmust enter waypoint2, 1, and 3 in thatorder when makingthe route.

Press the CLR key toexit this screen whenyou're finished.

FOLLOWING A ROUTETo follow a route, press the RTE key, then press the F2(RECALL ROUTE) key. The screen shown on the nextpage appears. Route number one appears on the rightside of the screen. The list of waypoints used in the routeare shown beneath the route number and name. If you

55

wish to recall a different route, press the F1 or F2 keysto cycle through the available routes.

After you’ve selected the desired route, you’ll notice ablack box surrounding the first waypoint in the route.This is the starting waypoint box. If you wish to start theroute using the firstwaypoint in the route,simply press the F4(START) key. How-ever, if you wish tostart the route usinga different waypoint,simply press thedown arrow key tomove the black boxto the desired way-point number. Thenpress the F4 key.

To follow a route backwards, press the F3 (REVERSE)key. For example, suppose you have three waypoints ina route and they’re numbered 2, 1, and 3. If you travelforward through the route, the unit will show navigationdata to waypoint number 2 first, then 1, and finally 3. Ifyou travel backward through the route, the unit will startwith waypoint number 3 first, then 1, and end withwaypoint number 2. No matter if you travel forward orreverse through the route, when you reach the lastwaypoint in the route, the arrival alarm sounds until youeither mute it or turn it off. Use the "Cancel Navigation"feature to stop the unit from navigating to the lastwaypoint in the route.

IMPORTANT!Turning the arrival alarm off prevents the AccuNavSport™ from sequencing to the next waypoint in theroute. This, in effect, turns the route off. The unit will stillshow navigation data to the current waypoint in theroute at the time the arrival alarm was turned off.

56

MODIFYING A ROUTEAny part of a route can be changed at any time. Forexample, suppose you have a route consisting of way-points number 2, 1, and 3 and you wish to changewaypoint number 3 to waypoint number 5. Simply pressthe RTE key, then press the F1 key. Route number oneappears on the rightside of the screen.The list of waypointsused in the route areshown beneath theroute number andname.

CHANGING GPS SETTINGSFor the fastest position acquisition, the AccuNav Sport™must be initialized when it’s turned on for the first time.This is described at the beginning of the GPS section inthis manual. However, if you wish to change only one ofthe parameters (such as time), press the MENU key,then press the F5“CHANGE GPS SET-TINGS” key. Finally,press the F1 “LAT,LON, ALT, TIME,DATE” key. Thescreen shown at rightappears.Using the menus onthis and followingmenu pages, you canchange the initial po-

sition, time, date, or altitude without affecting any otherinitialization setting. All of these menus work identicallyto the ones described in the initialization section at thebeginning of the GPS section. After you make a change,the unit returns to the GPS or plotter screen.

You may need to re-initialize the unit if you move a longdistance (over 100 miles) with the unit off. In this caseyou would need to enter a new initial position to help theAccuNav Sport™ find the correct satellites quicker.

GPS MODULE SELF-TESTThis feature tests the GPS module and returns a specialcode. This code is of interest only to the service depart-ment. However, the AccuNav Sport™ interprets thiscode and displays a status message. This message iseither “MODULE HAS PASSED” or “MODULE HASFAILED” and shows at the bottom of the screen. The

61

current software version number also appears near thebottom of the screen. Contact the factory customerservice department if the module fails the self test. DONOT ATTEMPT TO USE THIS PRODUCT IF IT FAILSTHE SELF TEST.

To use the self test fea-ture, press the MENUkey twice , then pressthe F4 (GPS MODULESELF TEST) key. Thescreen shown at rightappears.

To exit from thisscreen, press theCLEAR key.

GPS SIMULATORThis feature places position and navigation data on allscreens, including the plotter. The unit “navigates” aclosed course. It shows bearing and distance to go,course over ground, and other information. A recurringmessage appears, alerting you that the simulator modeis enabled. DON’T NAVIGATE WHEN THE SIMULA-TOR IS ON!

To turn the simulator on, press the MENU key twice,then press the F5 (GPS SIMULATOR OFF ON) key. Thesimulator mode starts immediately. To turn the simula-tor off, either press and hold the OFF key or repeat theabove steps.

NMEA/DGPS WIRINGThe AccuNav Sport™ can send NMEA 0183, version1.5 data to another device. It can also receive positioncorrection data from a DGPS (Differential GPS) beaconreceiver for high position accuracy. A connector on theback of the unit (see photo at right) is used for theseconnections. A rubber plug covers this connector whenit's not in use.

The following NMEA 0183 sentences are sent from theAccuNav Sport™:GPRMB Minimum Recommended Sentence, Part BGPRMC Minimum Recommended Sentence, Part CGPGLL Present Position - Latitude/LongitudeLCGLL . Present Position - Latitude/LongitudeGPAPB Autopilot Steering Data

optional NDC-1 adapter cable. This cable has sevenwires- red, black, brown, blue, green, white and abraided shield. The red (positive) and shield (ground)wires are power input (+6 to +35 VDC) to the AccuNavSport™. If the red wire is not used, tape its end so thatit cannot short. The white and green wires are for aNMEA interface and/or a DGPS beacon receiver. TheAccuNav Sport sends data to another electronic naviga-tion devices through the white wire and receives datafrom a beacon receiver through the green wire. Theblue, black, and brown wires are not used.

To connect a device to the AccuNav Sport's white orgreen wires, attach a twisted pair cable from thedevice's NMEA input to the white wire on the NDC-1cable. Solder the ground conductor of the twisted pairto the shield wire on the AccuNav Sport's NDC-1cable. See the other instrument's manual for morewiring instructions.

64

SELECT NMEAThe AccuNav Sport sends data out the white wire on theoptional NMEA cable according to standards set by theNMEA (National Marine Electronics Association). Thisallows the AccuNav Sport to send position and naviga-tion information to “listener” units, such as chartinginstruments, autopi-lots, and other ma-rine instruments. TheAccuNav Sport usesthe following NMEAdata protocols:NMEA 0180 and0183. NMEA 0180sends steering infor-mation only. It’s use-ful mainly for marineautopilots. NMEA

0183 sends position, steering, speed, and more. Inorder to use this feature, the white wire on the optionalNMEA cable must be connected to the NMEA data inputon the other instrument. See the installation section inthe front of this manual for wiring connection informa-tion.

The AccuNav Sport also has the capability to receivedifferential data from a beacon receiver. This gives theunit much better accuracy than normal. However, be-fore purchasing and installing a beacon receiver, makecertain there are transmitters in the area you wish touse. Presently, the AccuNav Sport can use the Mag-navox MX-50R or StarLink MRB-2A. Please note thatthe AccuNav Sport doesn't send NMEA 0183 data whenthe Magnavox MX-50R beacon receiver is activated.

65

NMEA SETUPOnce you connect the wiring properly, the AccuNavSport must be told which NMEA data format to use.Consult the owner’s manual of the other equipment tosee which format it needs. Then set the AccuNav Sportas follows:

First, press the MENU key. Next, press the F5 (CHANGEGPS SETTINGS) key. Now press the F2 (SELECTNMEA/DGPS) key. The screen shown on the previouspage appears.

The data format currently in use shows at the top of thescreen. Press the key corresponding to the desired dataoutput. Now press the CLR key. The AccuNav Sport willreturn to the last used GPS screen and send NMEA dataout the NDC-1 NMEA/DGPS interface cable.

DGPS (Differential GPS) BEACON RECEIVER SETUPYou'll have to tell the AccuNav Sport which beaconreceiver's data to expect and set up the parameters forthat data. To do this, first press the MENU key. Next,press the F5 (CHANGE GPS SETTINGS) key. Nowpress the F2 (SELECT NMEA/DGPS) key. Press thekey corresponding tothe desired beaconreceiver. Finally,press the F6 (SETUPBEACON DATA) key.The screen shown atright appears.

The station frequencyand bit rate are shownon the right side ofthe screen. Press theF1 key which corre-

This page shows the station ID number, its frequencyand bit rate, the "health" of the station (0 = best, 5 =worst), signal strength (the higher the number, thebetter), and the signal-to-noise ratio (SNR). The higherthe SNR number, the better. The lower half of the screenshows statistics for each of the receiver's five channels.This includes the sat-ellite number (PRN),its status (STAT), theUser DifferentialRange Error(UDRE), Time status(TIME), and if SA(Selective Availabil-ity) is on or off. TheUDRE is the rangeerror from your posi-tion to the satellite. If

sponds to the "INC FREQ" to increase the stationfrequency or the F2 key (DEC FREQ) to decrease it. Dothe same for the bit rate. When the station frequencyand bit rate are adjusted to their proper settings, pressthe CLR key. The AccuNav Sport returns to the last usedGPS screen. The letters "DGPS" appear next to the"POSITION" on all screens that show your presentposition, showing that the beacon receiver is working.

To view the status of the beacon signal, press the MENUkey until the second menu page appears. Now press thekey corresponding to the "DIFFERENTIAL GPS STA-TUS" label. If the beacon receiver is receiving data fromthe transmitter and is connected properly to the AccuNavSport, a screen similar to the one shown at right ap-pears.

67

there is an "OK" in this field, then the range error to thatsatellite is 8 meters or less 68 percent of the time.

For more information, read your beacon receiver'smanual.

SELECT UNITS OF MEASUREThe AccuNav Sport™ can display distance in miles,kilometers, or nautical miles, velocity in miles per hour,kilometers per hour, or knots, bearing in degrees mag-netic or true, altitude in feet or meters, and time in 12hour or 24 hour format.

To change any these, first press the MENU key. Next,press the F5 (CHANGE GPS SETTINGS) key. Finally,press the F3 (SELECT UNITS OF MEASURE) key. Thescreen shown at right appears. The black box on eachline shows the unit of measure currently in use. On this

screen, the units of measure are in statute miles fordistance, miles per hour for velocity, degrees magneticfor bearing, altitude in feet, and time is in the 12 hourformat (A.M./P.M..)

Press the key corresponding to the unit that you wish tochange. For example,press the F1 key twiceto switch from miles tokilometers. Thismoves the black boxtwo times from the “MI”to the “KM”.

When you have theunits of measure setas desired, press theCLR key.

TRUE and MAGNETIC POSITIONTrue and magnetic north are not the same. True north isthe top of the world. It’s where all lines of longitudeconverge. Magnetic north is the location our compassespoint. It lies several hundred miles to the south of truenorth, at a location in Canada.

Charts are usually laid out according to a Mercatorprojection that uses true north. If you plot a course on achart using the Mercator projection, you’ll either have toconvert magnetic readings to true or use true readings.

The AccuNav Sport can display navigation informationin magnetic or true. When it’s turned on for the first timemagnetic is used. To switch to true, first press the MENUkey. Next, press the F5 (CHANGE GPS SETTINGS)key. Finally, press the F3 (SELECT UNITS OF MEA-SURE) key. The screen shown on the previous page

appears. Now press the F3 (BEARING) key. This movesthe black box from “MAG” to “TRU.” Press the CLR keywhen you’re finished. This saves your changes andreturns to the GPS screen.

BACK LIGHT ON/OFFBoth the display and keyboard are backlighted for useat night. To prevent excessive current drain on thebatteries, when the battery voltage is less than 9.0 volts,the lights will stay on for 30 seconds, then automaticallyturn off. Press any key to turn them on again. To turn theback lighting on, simply press the ON key. To turn thebacklights off, press the ON key again. There is a backlight on/off switch on the position screen's third menupage, also.

69

BACKLIGHT ADJUSTThe intensity of the backlighting is adjustable. To changeit, press the MENU key three times, then press the F2(ADJUST BACK LIGHT LEVEL) key. A screen similar tothe one below appears. The light adjustment menushows at the bottomof the screen. Pressthe left arrow key todecrease the lightlevel, the right arrowkey to increase it.When the light is setto the desired level,press the CLR key toerase this menu.

PRESETThe Preset feature returns all GPS units to their originalfactory settings. This resets the units of measure, speakervolume, display contrast, and more. This doesn’t eraseany waypoints or routes, however it does erase plottertrails.

To preset the unit, press the MENU key until the “PRE-SET UNIT” label appears. Press the key correspondingto that label. The menu screen disappears and theAccuNav Sport™ returns to the GPS position screen. Allunits will be returned to their factory settings.

PCF OFFSETThe GPS navigation system relies on complex math-ematical calculations to determine your position basedon satellite data and other factors. One factor is theEarth's shape. Since the Earth is not a true sphere,variations in the calculations have to be made to accom-modate deviations. To make matters more complex, noteveryone uses the same data to determine what thedeviations are. The size and shape of the ellipsoids thatare used to approximate the earth's surface are im-proved often. This can lead to errors if your navigationdevice uses one ellipsoid, while your chart uses adifferent one. The term used for these ellipsoids is"Datum."

To reduce the error factor between datum, this unit givesyou the capability to move or "offset" the position shownon the display to match the one on the chart. The unit will

add this offset to all position displays at all times.

Remember, the GPS error is very dynamic and the PCFoffset should never be used in an attempt to cancel theerror. In general terms this feature should only be usedif your map indicates what the possible error is. Thisfeature should always be reset to zero (0) whenyou're finished with that chart.

For example, suppose you are stopped at a location thatis accurately marked on a chart. Your unit shows alongitude position that is .010 degrees less than the oneon the chart. Using the Position Correction Factor (PCF)Offset feature, you make the unit read the same as thechart. If you move, the unit will continuously add thechange to all position displays. This makes it moreclosely match the datum used by the chart. For thisreason, you should be careful when entering the PCF

71

offset. This offset is saved in memory. It doesn't changewhen the unit is turned off. However, a Preset doeserase the PCF factor.

To set the PCF factor, first press the MENU key, thenpress the key corresponding to the "CHANGE GPSSETTINGS" label.Now press the F5(ADJUST PCF OFF-SET") key. Thescreen shown at rightappears.

Now press the F6 keyto enter the correc-tion factor for your lo-cation. The screen

shown below appears. Remember, this is the differencebetween the location shown on the present positiondisplay and the position shown on the chart.

Use the right and left arrow keys to move the black boxto the number that you wish to change in the latitude,then enter the num-bers.

Use the up or downarrow keys to changethe latitude from northto south, if necessary.Press the ENT keywhen you've enteredthe desired latitude off-set. Repeat this pro-cedure to change the

72

longitude. In this example, we have entered .012degrees south latitude and .068 degrees west longitudeas the PCF offset. That is the difference between thepresent position shown on the unit and our positionshown by the chart. In other words, our position shownon the unit is 0.012 degrees north and 0.068 degreeseast of the position shown on the chart.

After you've entered the desired offset, press the F4key. This turns the PCF correction factor that youentered on. To leave this screen, press the CLR key.This returns the unit to the last used GPS screen. It alsoputs your changes into effect.

To turn these changes off, return to this screen andpress the F4 key. Remember, presetting the unit alsoerases any PCF offset, thereby turning it off.
