INTRODUCTION The AccuNav Sport™ is a high quality, big screen handheld GPS receiver with performance that is second to none in its class. Using menu features and raised softkey operation, the AccuNav Sport™ is also one of the easiest to use products that Eagle has ever built. The wide screen shows the navigation and plotter screens with high resolution and detail. The display and keyboard are also lighted for night operation. The electronics are sealed inside the welded, dry nitrogen filled case.
GPS - HOW IT WORKS The Global Positioning System (GPS) is perhaps the best approach to navigation that has ever been devised. Conceived by the Department of Defense (DOD) and the United States military, the GPS system is an answer to their needs of 24 hour global positioning, 365 days a year. Basically, the system works by using a constellation of satellites orbiting Earth 11,000 miles in space. There will be 24 satellites in orbit when the system is fully operational.
As the receiver locks 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. Each satellite has an extremely accurate clock that tells the receiver when the radio transmission started. The receiver compares that time against its own clock, thus it knows how long it took the radio signal (travelling at the speed of light!) to reach it. If you know time and speed, then you can calculate distance.
the better), and other factors. The smallest ranges on the plotter may not be usable if the SA is high. The present position symbol can move off the screen even while you’re sitting still. Don’t let this discourage you. GPS by nature has much faster updates than other systems (such as Loran), and typically is much easier to use. Accuracy, even with SA on is still better than most other navigation systems. You’ve purchased one of the finest navigation instruments on the market today.
ANTI-SKID The AccuNav Sport™ has a recess molded into the back of the case and one-half of a plastic fastener attached to the recess. When used with the other half of the fastener, it keeps the unit from sliding on a level surface such as a dashboard. NOTE: The adhesive anti-skid patch is not designed to hold the AccuNav Sport™ on a vertical or overhead surface. It is only to be used to keep the unit from sliding on a flat, horizontal surface.
EXTERNAL POWER EXTERNAL POWER The AccuNav Sport™ uses six AA batteries or (using the optional CA-1 adapter cable) 6 to 35 volts DC from an external power source. To use external power (such as a car's cigarette lighter), simply push the CA-1's plug into the small connector on the side of the AccuNav Sport™. Plug the other end of the CA-1 into the vehicle's cigarette lighter, and the AccuNav Sport is ready for use.
BATTERY INSTALLATION BATTERY INSTALLATION The AccuNav Sport™ requires six AA batteries. We recommend DuraCell™ alkaline batteries, but other brands will work. You can use lithium batteries which will last longer than alkaline batteries. Rechargeable ni-cad batteries will also work in the AccuNav Sport™, however they won't last as long as alkalines. Do Not use heavy-duty batteries or any battery other than the ones listed above. Do not mix different types of batteries. (e.g.
Now push the battery pack out the bottom of the battery cover as shown at right. Install the batteries with the negative end (-) toward the springs. The positive end (+) should be firmly against the metal plate. When all six batteries are installed in the battery pack, slide it into the battery cover. BATTERY INSTALLATION Notice! There is a tab on the top of the battery holder that aligns with a slot on the top of the battery cover.
9 BATTERY SAVER Vari-Power™ Battery Saver Feature The AccuNav Sport™ has a five-level power saving feature that can extend the life of the batteries considerably. It does this by changing the update rate of the GPS receiver inside the unit. When you first turn the AccuNav Sport on, the update rate is once per second. In other words, the GPS receiver calculates and sends your position to the display once per second. You can lengthen this time to as little as once every five seconds.
BATTERY SAVER due to the trees overhead. When this happens, the unit automatically goes into the one second update mode until it locks onto the satellites. Then it returns to the five second mode. If you are walking through heavy tree coverage with only occasional gaps in the trees, the unit may remain in the one second update mode continuously. Typically, however, the AccuNav Sport™ will consume less power with higher update rates under normal conditions.
Now press the right arrow key to see the second menu screen. The screen shown on the previous page appears. Press the F1 key which corresponds to the "POWER SAVING SETUP" label. A screen similar to the one below appears. 11 LOW BATTERY INDICATOR When the battery voltage reaches six volts, a low battery message appears in the lower left corner of the display.
ANTENNA The AccuNav Sport™ has a removable antenna that folds over the display when the unit is not in use. To open the antenna, simply lift on an edge of the antenna and raise it to the desired angle. Two thumbscrews on the antenna's hinge let you adjust the tension on the antenna. This helps keep the antenna in the desired position. The thumbscrews work in opposite directions. To tighten the right thumbscrew, rotate it away from the display. To tighten the left thumbscrew, rotate it toward the display.
To remove the antenna, simply loosen the thumbwheels until they won't turn. Carefully remove the antenna from the unit by pulling it straight out. If you feel any resistance, make certain the thumbwheels are at the end of their travel. Don't force any parts. Once you remove the antenna, you can see it's connector inside the left-hand thumbwheel. When reinstalling the antenna, align the left side of the antenna first, then thread left thumbwheel until it engages the connector.
ANTENNA ANGLE When using the AccuNav Sport™, try to make certain the antenna is parallel with the ground, or nearly so as shown at right. Since the signals from the satellites are "line of sight", a flat antenna gives you a better chance of being able to receive the signals from all of the available satellites. Also, trees, buildings, carports (even your body), can block the signals from the satellites.
KEYBOARD The keyboard has the main group of keys arranged in three horizontal rows, plus four arrow keys at the top. The keys are used to enter numbers, make menu selections and activate the windows feature. The menu key near the bottom left corner of the keyboard activates the first menu page. WIN - This key gives you access to the windows mode, which has many combination displays. POS - Press this key to show the Position Screen. STR - Press this key to show the Steering Screen.
WPT - Pressing this key lets you save or recall a waypoint. ICON - To mark a location on the plotter screen, use this feature. CNTR - Pressing this key centers your position on the plotter. ZIN & ZOUT - These keys let you "zoom-in" or "zoomout" the plotter display. OFF - Press and HOLD the Off key to turn the AccuNav Sport™ off. MENU - Press this key to show the menus and gain access to most functions. 16 ENT - (Enter) Press this key to accept keyboard entry.
OPERATION TURNING POWER ON To turn the AccuNav Sport™ on, simply press the "ON" key. (Note: The "ON" key is harder to press than the other keys. This makes it harder to turn the AccuNav Sport™ on accidentally.) A screen similar to the one shown below appears. To turn the lights on, press the F5 key. To adjust the display contrast, press the left arrow key to lighten the screen, the right arrow key darkens it. To clear the display, press the CLR key.
MENUS Most of the AccuNav Sport's™ features are found on pages of "menus". Pressing the MENU key lets you view the menus. This unit has four basic displays. They are: Windows, Position, Steering, and Plotter. When you press the MENU key, different menus appear depending on the display mode the unit is in. (Except the plotter and steering displays share the same menus.) In other words, if you press the MENU key while the position screen is showing, the menu shown at right appears.
Initialization - Power On In order for the AccuNav Sport™ to lock onto the satellites, it must first find them. If you simply turn the unit on and wait, the unit will find the satellites by itself in 15 minutes or less. This is called “Cold Start.” If you let it find the satellites, the time display will probably be wrong, since it will be showing UTC time which is the time at Greenwich, England. However, all other navigation displays, including the position display will be correct.
This is the GPS setup screen. The settings now in use are shown at the top of the display. If you’re using the unit for the first time, these settings are probably wrong for your position and time. To change any of the numbers on this display, first press an up or down arrow key to move the black box to the desired label. For example, to change the local time, press the down arrow key until the black box is on the “LOCAL TIME”, press the F6 key, then enter your time using the numbered keys.
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 up or down arrow keys to switch to east or west longitude, if necessary. Now enter the longitude using the numbered keys. Be certain to enter a zero “0” as the first number in the longitude if it’s less than 100 degrees! After you’ve entered the last number, press the ENT key.
Use the number keys to enter the time. Press the up arrow key to change the time from AM to PM or the down arrow key to change from PM to AM. Press the ENT key when you’re finished. CHANGE DATE To enter today’s date, move the black box to the LOCAL DATE display, then press the F6 key. The screen shown on the next page appears. Enter the date using the numbered keys. When you’re finished, press the ENT key. 22 The numbers at the top of the screen should be correct.
COLD START When 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 cold start message to the receiver at any time. If the unit can’t lock on to the satellites using the data you’ve given it, or if it has trouble finding the satellites, perhaps it is using the wrong data. This can happen if you’ve entered the wrong data by accident. For example, giving it east longitude instead of west.
POSITION/NAVIGATION DISPLAYS The AccuNav Sport™ has a position screen, plotter, steering indicator, and a satellite information screen. These displays were designed to show the most important data. However, using the Windows feature, many more screens are available that show navigation information in various arrangements. See the Windows section for more detail.
SATELLITE INFORMATION SCREEN The satellite information screen shows technical data about each satellite in view. The AccuNav Sport™ has a five parallel channel GPS receiver. Data on each channel is shown at the top of the display. The channels are numbered one through five on the left side of the screen. Every satellite in the constellation has a number assigned to it, called the PRN. The PRN is the first number in the channel’s row. TRK stands for “track.
value of HDOP, VDOP, and TDOP. The smaller the GDOP’s number is, the better. The GPS receiver selects satellites based on GDOP, therefore it always tries to use satellites that have good DOP values. These depend on the azimuth and elevation of the satellite, and any ground based obstructions. Remember, the smaller the number - the better on all of the DOPs.
are the Local Time and Cross Track Error Displays. Please note that you must recall a waypoint to use the Bearing and Cross Track Error displays. STEERING SCREEN The steering screen shows a pictorial view of your vehicle and course travelled. This is called a Course Deviation Indicator or CDI. It also shows Distance To Go (DTG), Speed Over Ground (SOG), Bearing to Waypoint (BRG), and Course Over Ground (COG). Press the STEER key to view this screen. Your present position is shown by the arrow.

NMEA/DGPS WIRING The AccuNav Sport™ can send NMEA 0183, version 1.5 data to another device. It can also receive position correction data from a DGPS (Differential GPS) beacon receiver for high position accuracy. A connector on the back of the unit (see photo at right) is used for these connections. A rubber plug covers this connector when it's not in use.
WHITE (+) SHIELD (-) FUSE RED ACCUNAV SPORT SENDING DATA TO ANOTHER DEVICE ACCUNAV SPORT optional NDC-1 adapter cable. This cable has seven wires- red, black, brown, blue, green, white and a braided shield. The red (positive) and shield (ground) wires are power input (+6 to +35 VDC) to the AccuNav Sport™. If the red wire is not used, tape its end so that it cannot short. The white and green wires are for a NMEA interface and/or a DGPS beacon receiver.
SELECT NMEA The AccuNav Sport sends data out the white wire on the optional NMEA cable according to standards set by the NMEA (National Marine Electronics Association). This allows the AccuNav Sport to send position and navigation information to “listener” units, such as charting instruments, autopilots, and other marine instruments. The AccuNav Sport uses the following NMEA data protocols: NMEA 0180 and 0183. NMEA 0180 sends steering information only. It’s useful mainly for marine autopilots.
NMEA SETUP Once you connect the wiring properly, the AccuNav Sport must be told which NMEA data format to use. Consult the owner’s manual of the other equipment to see which format it needs. Then set the AccuNav Sport as follows: First, press the MENU key. Next, press the F5 (CHANGE GPS SETTINGS) key. Now press the F2 (SELECT NMEA/DGPS) key. The screen shown on the previous page appears.

TRUE and MAGNETIC POSITION True and magnetic north are not the same. True north is the top of the world. It’s where all lines of longitude converge. Magnetic north is the location our compasses point. It lies several hundred miles to the south of true north, at a location in Canada. Charts are usually laid out according to a Mercator projection that uses true north. If you plot a course on a chart using the Mercator projection, you’ll either have to convert magnetic readings to true or use true readings.
BACKLIGHT ADJUST The intensity of the backlighting is adjustable. To change it, press the MENU key three times, then press the F2 (ADJUST BACK LIGHT LEVEL) key. A screen similar to the one below appears. The light adjustment menu shows at the bottom of the screen. Press the left arrow key to decrease the light level, the right arrow key to increase it. When the light is set to the desired level, press the CLR key to erase this menu.
PCF OFFSET The GPS navigation system relies on complex mathematical calculations to determine your position based on satellite data and other factors. One factor is the Earth's shape. Since the Earth is 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 approximate the earth's surface are improved often.
