USE THIS GPS RECEIVER ONLY AS AN AID TO NAVIGATION. A CAREFUL NAVIGATOR NEVER RELYS ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. CAUTION This GPS receiver,(like all GE'S navigation equipment) will show the shortest, most direct path to a waypoint. It provides navigation data to the waypoint regardless of obstructions. Therefore, the pnident navigatorwill not only take advantage of all available navigation tools when travellingto a waypoint, but will also visually check to make certain a clear, sate path to the waypoint is always available. NOTICE! As of this writing, the Department of Defense (DOD) has not declaredthe GPS navigation systemas operational. The system is still in a testing phase. Satellites can beturned off or accuracy can be degraded at will by the system operators. Remember that the GlobalNav, or any GPS receiveris only as accurate as the systemit's using.

It rivals other GPS units costing much more in both features and performance. The GlobalNav offers easy-to-use operation at the touchof a button. Although the GlobalNav has many features and functions, the "soft key" menu systemmakesit easy to use. Above all, don't be afraid to try different features and functions on the unit. You can't hurt it by pressing buttons! Read this manual and take ft with you the first fewtimes you use your unit. It makes a great reference should you need it. The more you know when you get to the water, the more your GlobalNav can do for you! MOUNTING Install the GlobalNav in anyconvenientlocation,providedthere is clearance behind the unit when it is tilted for the best viewing angle. Holes in the bracket base allow wood screw or throughbolt mounting. You may need to place a piece of plywood on the back of thin fiberglass panels to secure the mounting hardware. Make certain there is enough room behind the unit to attach the power and GPS cables. The smallest hole that will pass the GPS module's connector is 9116". After drilling the hole, pass the GPS connector up throughthe hole first, then passthe power cable down through it. After the cables have been routed, fill the hole with a good marine sealingcompound. Offset the bracket to coverthe hole. POWER CONNECTIONS The GlobalNav works from a twelve-volt battery system only. You can attach the powercable to an accessoryor power buss, however if you have problems with electrical interference, then attach the power cable directlyto the battery. If the cable is not long enough, splice#18 gauge wire onto it. PDF compression, OCR, web-optimization with CVISION's PdfCompressor I The power cable has three wires; red, white, and black. Red is the posilive lead, black is negativeor ground. Attach the in-line fuse holder to the red lead as close to the power source as possible. For example, if you haveto extendthe power cable to the battery or power buss, attach the fuse holder directly to the battery or power buss. This will protect both the unit and the powercable inthe eventof a short. Thewhitewire is for a NMEA interface. The GlobalNavsendsdata for anotherelectronic navigation devices through this wire. If the white wire is not used, tape the end so that it cannotshort. To connect a device to the GlobalNav's NMEA output, attach a shielded,twisted pair cable fromthedevice's NMEA intputto the white wire on the GlobalNav's power cable. Solderthe ground conductor of the twisted pair and the shield to the black wire on the power cable. Do not connectthe shield to the other device. See the other instrument'smanual for more wiring instructions.

The GlobalNav automatically sends NMEA data out the while wire once it acquires and 'locks on" to the satellites. GPS MODULE INSTALLATION The GPS module can be installed on a flat surface or (with the suppliedadapter) on a pole. Mount the module in an area that guarantees a clear view of the sky at all times. In order for the module to receive the signals from the satellites, it must not be obstructed. An ideal location is on a cabin roof, or deck. The gunnels also make a good location. Attachingthe pole mounting adapter lets you install the module on a one inch mast. A high location is preferred. However, for lightning protection, the antenna shouln'lbe the highest part of the boat. Surface Mounting - With Access If you have access underneath the mounting surface, use the gasket suppliedwith the GPS module as a template. Drill four 7/32" holesand one 9/16" hole for themodule's cable. Attachthe cable to the module and pass it down through the hole in the gasket and the mounting surface. Use #10-32 machine screws (not included) to fastenthe GPS moduleto the mountingsurface.

MAN OVERBOARD Oneof boating's'mostterrifying events is havinga friend or family member fall overboard. This situation can be deadly on any body of water, fresh or salt. It's particularly dangerous at night or if you're out of sight 01 land. Of Oourse, the first thing to do is remain calm and try all standard safety measures to try and rescue the person. If you lose sight of the person, you can use the GlobalNav to initiate a searchpattern. Once you're back at the helm after initial rescue efforts have failed, press the GlobalNav's Waypoint Quicksave key. This instantly stores your present positionin memory. Memorizethe waypoint number that appears at the top of the screen! Now press the WaypointRecall key. Pressthe key next to the 'Vest. Waypt Num." near the bottom of the screen. A new menu appears. Enter the waypoint number that you just saved, then press the key adjacent to the "ENTER" label. This recalls the waypoint you stored, causingthe GlobalNav to show navigation information back to that waypoint. The Arrival alarm will sound since you're within ft's radius, either ignoreit or pressthe CLEAR key to silence it. Using the unit in this manner lets you start a search pattern for the victim from a known location. Switching to the plotter on the .05 mile range makes it easierto see your positionrelative to the accident area. Remember, saving the victim is the primarygoal. Try all options to rescue the person immediately after the accident happens. Training and education are also good accident preventatives. The CoastGuard has excellent safetycourses. Instruct all members on board your boat on safetyprocedures before leaving the dock. Make certain all on board know what to do before any emergencyoccurs. ON - The ON key turns the GlobalNav on. WAYPT QUICKSAVE- Pressing this key instantly saves your presentposition. WAYPOINTSAVE - This feature gives you more waypoint saving options.

Set as Offset To enter the offset or difference in position from your present position and the one on the chart, first subtract your current position from the location on the chart you wish to match. For example, if your location is N 32°10.220', W 80012.1061 and the chart's positionis N 3215.604', W 08012.714, then the position offset is N 00°05.384, W 0O°O0.608'. Ppressthe MENU key, then press the keyadjacentto the "More" label until the "POF Adjustment" label appears. Press the key adjacent to that label. The screen shown at the top of the previous page appears. Now press the key adjacent to the "Set as Offset" label. The screen shown below left appears. Enter the differencebetween your position and the chart's location in latitude and longitude. After pressing the key adjacent to that label, the screen shown below right appears. GPS - HOW IT WORKS The Global Positioning System(GPS) is the newest, most hightech approach to navigation yet devised. Conceived by the Department of Defence (DOD) and the United States military, the GPS system is an answerto their needs of 24 hour global positioning, 365 days a year. Basically, the systemworks by using a constellationof satellites orbiting Earth 11,000 miles in space. Therewill be 21 satellitesin orbit when the system is fully operational. Three more satellites will act as spares, for a total of 24. When all satetlites are in place, at least four of them will be in view nearly anywhere on Earth twenty four hours a day. The GPS receiver requires at : J Clear I S 00°05.384' E000° 00.608' North/South Lat. I East/West Long. Use Clear PCF Offset least three satellitesto give a "2D" fix. (A 2D fix is your position in latitude/longitude. A 3D Iix is your latitude/longitudeplus altitude.) When the GlobalNav lockson to at least four satellites, it displaysa 3D fix. Position L to PDF compression, OCR, web-optimization with CVISION's PdfCompressor 'IA determine position If you need to switch the latitude from north to south, press the key adjacent tot he "North/South Lat." label. Switchthelongitude if necessary in the same manner by pressingthe key next to the "East/West Long." label. If the offset shown at the top of the screen is correct, press the key adjacent to the "Use Position" label. The GlobalNav returns to the last used position, navigation, or plotter screen using the offset information you entered. To verify that POF is in effect, switch to the positjon, navigation, or plotter screen. The letters "POP appear on these screens when POE is enabled. It takes three satellites As the receiver lacks on to each satellite, it calculates the distance from the satellite by measuring the length of time it takes the radio signal to reach it. The satellites have an extremely accurate clock and it tells the receiverwhen the radio transmission started. The receiver compares that time against its own clock, thus it knows how long it lookthe radio signal (travelling at thespeed of light!) to reach it. If you know time and speed, then you can calculate distance. Once you have this from three satellites, then the receivercan determine position. The Globalwavgives you a choice of methodsto enter the PCF. The first method (Set as Position) lets you simply enter the corrected latitude/longitude. The second method (Set as Offset) requires a calculation be performed, then entered into the GlobalNav. Set as Position To use the Set as Positionmethod, first choose the locationon the chart that you wish to match the unit's position display to. Then move the boat to that position and hold it there as accurately as possible. Now press the MENU key, then the key adjacent to the "More" label until the "PCF Adjustment"label appears. Press the key adjacent to that label. The screen shown below appears. N V ACCURACY Most of us have heard tales of extraordinary accuracyfrom OPS receivers. The DOD requires accuracyof 10 to 15 meters from the satellite system. However, onlythe military gets this precision. The way the military keeps us and other unauthorized people from using the more precise system is coding. In other words, the data coming from the satellites is encrypted. Civilian GPS receiversuse what'sknown as "CIA Code." It's intentionally worse than the military's "P Code." In this manner, civilian users worldwide can benefit from excellent positionfixes. Meanwhile, the military keeps the most accuratesystemaway from potential enemies. Theoretically, C/A code can give accurate position fixes up to 15 meters. This is more than adequate for most people.

I(,J PCF Position However (as of this writing), the militaryisn't satisfied with CIA's potential accuracyin thehandsof theworld. So, it's degradingit further with what's called "Selective Availablity" or SA. This is small, random errors intentionally added to the system so your accuracywill typicallybe within 100 meters. Of course, accuracy also depends on the angle of the satellite above the horizon, signal-to-noise ratio, the numberof satellitestracked at one time (the more the better), and other factors. Don't let this discourage you, however. Our tests have repeatablyshown betterthan 100 meteraccuracy. Furthermore, GPS by nature has much faster updates than other systems (such as Loran), and typically is much easier to use. You've purchasedone of thefinest navigation instwmentson the market today. We hope you'll enjoy it fgr many yearsto come. $IJ N Lcic1 I t 4 u----°--. ---' ----°----. ------' i, thaaI I19!'94 , PCF Position N 32° 10 220' 106' North/South Lat. L East/West Long.

A message similarto theone below will be displayed. GlobalNav Version: 1.0 Copyright 1991 Lowrance Electronics The Lowrance GPS Module This GPS receiver(manufactured by Rockwell) currently is used in all Lowrance GPS receivers. It's small, rugged, and fast. The five channel design lets it acquire and track up to all satellites in view at all times. It transmits position information to the GlobalNavonce everysecond. By incorporating Rockwell'sGPS receivertechnology with Lowrance's state-of-the-art design and manufacturing capabilities, Lowrance brings you the most advanced line of GPSnavigation systems available in the world. GETTING STARTED Pressthe key adjacent totheCLEAR label to erase this message and return to the sonar screen. Initialization - Power On The GlobalNav must be initialized or "told where it is" the first time it's turned on. This initialization process is usually done only once and requires the following data: 1. Presentpositionin latitude/longitude 2. Elevationabove sea level (altitude) 3. Today's date and time 4. Numberof hours from Greenwich, England (UTC) TheGPS navigation systemrelies on complexmathematical calculations to determine your positionbased on satellite data and other factors. One factor is the Earth's shape. Since the Earthis not a true sphere, variations in the calculations have to be made to accommodate deviations. To make matters more complex, not everyone uses the same data to determine what the deviations are. The size and shape of the ellipsoids that are used to approximatethe earth's surface are improved often. This can lead to errors if your navigation device uses one ellipsoid,while your chart uses a different one. The term used for these ellipsoids is "datum." PCF OFFSET (Position Correction Factor) To reduce the error factor between datum, the UltraNavGPS gives you the capabilityto moveor "offset"the positionshownon the display to match one shown on the chart. The unit will add this offset to all positiondisplays at all times. For example, suppose you are anchored at a location that is accurately marked on a chart. Your GlobalNav displaysa longitude positionthat is .010 degrees less than theone on thechart. Using the Position Correction Factor (PCF) Offset feature, you make the GlobalNav read the same as the chart. If you raise anchor and move, the GlobalNav will add the change you made to all positions. This makes it more closely match the datum used by the chart. For this reason, you should be careful when entering the PCF Offset. This is saved in memo'. It does not change when the unit is turnedoff. However, Preset does erase the PCF settings. 114 Everytime the GlobalNav is turned on, the screen shown below appears. This showsthe data that the GPS modulewill start with at power on. This is neededby the GlobalNavto tell the GPS module which satellites are visible so it can determineyour position faster. Please check it every time you turn the unit on to make certain that it is correct. If it is correct, simply press the CLEAR key to erase the screen.

FT It EnterI NMEA COMMUNICATION The GlobalNavsends data out thewhitewire on thepower cable accordingto standardsset by the NMEA (National Marine Electronics Association). This allows the GlobalNav to send position, depth, and navigation information to "listener" units, such as charting instruments, autopilots, and other marine instruments. The GlobalNavuses the following NMEA data protocols: NMEA 0180, 0182, and 0183. NMEA 0180 sends steering information only. It's useful mainly for autopilots. NMEA 0183 hasthe most information, sending position, steering, speed, and more. In order to use thisfeature, thewhitewire on thepower cable must be connectedto the NMEA data input on the other instrument. See the installation sectionat the front of this manual for wiring connection information. i1earj Now enter your Altitude using the keys on both sides of the screen. After you've entered the numbers, a new screen appears as shown below. This lets you switch the numbers from positive to negative. In other words, use positive altitude when you're above sea level, use negative numbers if you're below it. Once the numbers on the display are correct, press the key adjacent to the 'Use Position" label. The GlobalNav then returns to the InitialSettingsscreen. Once the wiring is connected properly, the GlobalNav must be told which data formatto use. Consult the owner's manual of the "listener"equipmentto see the which format it needs.

The CDI alarm sounds an audible tone when the CDI indicator moves past a preset limit. Both alarms are set and adjustedfrom thesame menu. The arrival alarm sounds a tone when your positionis within the alarm's radius of a waypoint. For example, if the alarm's setting is .5 mile, then the alarm sounds a tone when you come within .5 miles of a waypoint. To set the arrivalalarm, first press the MENU key, then pressthe key next to the "More' label until the "Set Alarms" label appears. Now press the key adjacent to that label. The screen below appears.

The GPS position screen appears with the present position display flashing. The GlobalNav begins its search for the correct satellites. Once ft locks onto at least three of them, your position displays. The latitude/longitude position will stop flashing when theGlobalNavhas locked onto the necessary satellites. To view the satellite data, see the SatelliteStatus section in this manual. Nevernavigatewith this unit whenthepositionscreen flashesthe latitude/longitude! This means the unit is not usable for navigation. Always use more than one method to navigate. If you move a long distance from the last time you used the GlobalNav, you may need to re-initialize the unit. If you preset the GlobalNav, you will definitely need to re-initialize the unit. The 'Initial Setup" menu selection on the GPS' second menu page returnsyou to the initial setup menu, when needed. Otherwise, you shouldn't need to repeatthese steps. The GlobalNav has five main display modes. These are the Position, Navigation, Steering, Plotter, and Status displays.
