WARNINGS

USE GOOD JUDGEMENT

This product is an excellent navigation aid, but does not replace the need for

careful orienteering and good judgement. Never rely solely on one device for

navigating.

USE CARE

The Global Positioning System (GPS) is operated by the U.S. Government, which is

solely responsible for the accuracy and maintenance of GPS.

The accuracy of position fixes can be affected by the periodic adjustments to GPS

satellites made by the U.S. Government and is subject to change in accordance

with the Department of Defense civil GPS user policy and the Federal

Radionavigation Plan.

USE CAUTION

Accuracy can also be affected by poor satellite geometry. When the accuracy

warnings appear on the screen, use the data with extreme caution.

USE PROPER ACCESSORIES

Use only Magellan cables and antennas; the use of non-Magellan cables and

antennas may severely degrade performance or damage the receiver, and will void

the warranty.

Introduction

Your Magellan GPS receiver has the advanced navigation features that experienced navigators expect, yet is simple enough for the novice navigator. This manual is broken up into four chapters; Introduction, Getting Started, Reference, and Appendix. It is very important that you go through the Getting Started chapter first as it prepares your receiver for use and provides some basic instruction for getting you up and running with your GPS receiver.

The third chapter is a Reference Section for the features found in your receiver including step-by-step instructions on their use. Because of the advanced navigational features of the receiver some of the terminology used in these procedures may be new to you, but don’t let that slow you down. As you use the receiver such terms as waypoints, leg, route, etc. will quickly become familiar.

The final chapter of this manual, Appendix, contains some further explanations and information that will help you use your receiver and defines many of the terms that may be unfamiliar.

Packing List

The following items should be in your package:

Conventions Used In This Manual

WARNING: Warning messages will occur to alert you to

potential problems that may be encountered if you do not follow the directions carefully.

NOTE: Note messages are shown to provide important information that will assist you in understanding your Magellan receiver and its operation.

If you are following along with your receiver during the step-by-step instructions, you should make key presses whenever the key name is in bold text. Text where the key name is not bolded is informational but can be pressed if you desire.

The Reference section of this manual is divided up into the various operations that you can perform with your receiver. Each section is titled with the operation to be performed, a brief description of the operation and how it might be used, a graphic display of the key presses to be used as a "quick reference" for the operation, and a detailed description of the operation with the screens shown for clarity.

After you have used your receiver for a short period of time you will find that you will need to refer to this manual less and less and the graphic displays of the key presses will be all you will need to remind you of the steps required.

Getting Started

General Description

The Meridian XL is a self-contained hand-held GPS receiver designed for general purpose position locating and navigation. It has a removable quadrifilar antenna located on the upper right side of the receiver, a highcontrast backlit LCD, and keypad. Using three AA batteries, inserted from the battery door found behind and near the base of the receiver, the Meridian XL will operate continuously for up to 6 hours.

Receiver Accuracy. Before beginning, just a few words on the accuracy of your receiver. The satellite constellation used to provide the GPS information that your receiver uses was put into orbit and is maintained by the Department of Defense (DoD) for use by the U.S. armed forces and its allies. GPS positioning for general use produces an accuracy of 25 meters or better, far more accurate than anyone anticipated. Since the signals generated by these satellites are accessible to anyone, the DoD has introduced errors into the signals sent by the satellites for security reasons. These errors are referred to as Selective Availability (or SA).

At present, your GPS position will be accurate to within 100 meters horizontally and 150 meters vertically. This accuracy can be improved by using Differential GPS (DGPS), which is described later in the manual. SA means that 95% of the time, your horizontal coordinates will be within 100 meters of your actual position. Elevation may vary even further.

Connecting Receiver Power

Connecting Power to the Meridian XL. The Meridian XL receiver

operates on either three AA batteries or a 9-16 volt DC external power source. Before using the Magellan Meridian XL GPS receiver, you need to install the batteries by removing the battery compartment door as shown. While the battery compartment was designed to be moisture resistant, it is not sealed and will not prevent moisture from entering with prolonged exposure. Even when operating the Meridian XL with external power, the batteries are required to prevent loss of data if you should lose external power for any reason.

Insert the batteries as shown in the receiver and reinstall the battery cover. You are now ready to turn the receiver on.

The receiver’s memory has internal protection for power loss of up to 10 minutes. This allows you to change the batteries without losing the receiver’s memory provided that you change the batteries within the 10 minute time frame.

First Time Use - Initializing the Receiver

You do not need to initialize your receiver each time you use it. Follow these steps to initialize the Meridian XL if this is the first time you are using it, if the receiver memory has been cleared or if the receiver has been transported more than 300 miles while turned off. In the latter case, you are not automatically prompted by the receiver to reinitialize and the POSITION screen is displayed instead of the initialization warning after the start-up screens. The POSITION screen tells you the coordinates of the last position received. These coordinates are not necessarily those of your current position.

Inputting Approximate Position. To give your receiver an approximate idea of its current location, you will need to enter the approximate latitude, longitude, date, and time of where you are now.

Since you may not know the latitude and longitude coordinates of your present position, the Meridian XL provides you with a list of geographic regions in the receiver’s Initialize function under Setup. This allows you to choose the general area of the world you are in, and the specific country or province of your current position. Selecting the appropriate location from the list will give your receiver an approximate starting point for tracking satellites. This will greatly shorten the time it will take the receiver to get your position for the first time (referred to as Time To First Fix).

Turn the receiver on by holding down the POWER key until the start-up screens appear.

MAGELLAN

If the receiver has not been initialized previously, or if the receiver’s total memory has been cleared, you will see the following screen, prompting you to press ENTER to initialize.

Press ENTER to Initialize.

TO INITIALIZE

If you inadvertently press another key without initializing manually, the receiver displays the POSITION screen with null values for the latitude and longitude (00°00.00N, 000°00.00W). In this case, the receiver will self-initialize, which may take 15 minutes or more. The elevation mode will automatically switch from 2D to 3D, which is necessary to obtain a proper first fix. The recommended method is to press ENTER and initialize manually, which will allow the receiver to get a position fix sooner.

Using latitude and longitude will satisfy most of the users of this receiver, but you may use any of the other coordinate systems (UTM, OSGB, TDs, Irish Grid, Swiss Grid, Swedish Grid or Finnish Grid) to initialize the receiver. If you prefer one of these coordinate systems, select the desired coordinate system in the COORD. SYSTEM section of Setup, then access INITIALIZE. You will be prompted to enter the appropriate data in the format of the chosen coordinate system.

The region screen appears with a list of locations around the globe. This list extends to a second page which can be viewed using the UP/ DOWN ARROWs. Highlight the general area of the world where you are located and press ENTER.

A list of countries, provinces or states within that general area appears. Use the UP/DOWN ARROWs to select the country, province or state of your location and press ENTER.

The receiver displays the Initialize page with the highlight active in the elevation field. Use the LEFT/ RIGHT and UP/DOWN ARROWs to enter your present elevation if you know it, and press ENTER. If you do not know your elevation, simply press ENTER.

If this is not the first time you have used your receiver, or if it is the first time but your receiver has already begun acquiring satellite signals, the following time and date entry may not be displayed.

Input your local time. Take extra

care to input the time correctly (to within 10 minutes), including the AM/PM designator. Use the ARROW KEYs to change the time. Use the UP/DOWN ARROWs to change

“AM” to “PM” if necessary. When the time is correct, press ENTER.

Please note that if you are located in a half-hour time zone, you will need to manually reset the time, after the receiver has taken a position fix, by adding or subtracting one half hour. Please refer to Setup - Time Display for directions on resetting time.

Your receiver requires just one more piece of information and that is the date. Use the UP/

DOWN ARROWs and RIGHT/ LEFT ARROWs to set the correct

date. Your display should resemble the one shown at right. Doublecheck all of the information entered. Then, press ENTER.

If you notice that you made a mistake, press MNU, highlight SETUP, press

ENTER. Select INITIALIZE, press ENTER and start over.

Initializing With Known Coordinates

If you know your present latitude and longitude, you may enter them directly (instead of choosing a geographic location from the list). In this case, highlight ENTER COORD on the second page and press ENTER. The City Reference Chart, found in the appendix, provides coordinates of many major cities.

Proper Handling - Signal Reception

The illustrations show both the proper and improper placement of a fixed antenna on a boat. Also, the fellow trying to get a position fix on the deck of the boat would get better signals if he would move up to the bridge. Physical obstructions (buildings, large trees, etc.) will block satellite signals from reaching the receiver. If unable to get a position fix, move the receiver so it has a clearer view of the sky, allowing it to choose from all of the satellites currently available.

Good Antenna Location

Poor Antenna Location

Taking your First Fix

To get a position fix, you must be outside with a clear view of the sky and away from any large obstructions (buildings, large trees, etc.).

Rotate the antenna upward and hold the receiver in a comfortable position.

If the receiver is off, press the POWER key to turn the receiver on, or if you have just finished initializing the receiver, press the NAV key until the screen showing your coordinates is displayed. This screen is called the POSITION screen.

The POSITION screen appears with the latitude, longitude, and elevation that you entered in during INITIALIZE. The word “SEARCHING” appears indicating that the receiver is searching the sky for satellites.

In a short period of time, the receiver will locate the satellites and begin receiving information. The first indication of this is that “SEARCHING” is replaced with a bar graph indicating the receiver’s progress toward acquiring GPS data from the satellites.

Saving Your First Waypoint

You now have a position fix that defines your current location. During normal operation your receiver continuously computes your position and displays that information on the POSITION screen.

You can save this position in the receiver’s memory for use later on. This stored fix is referred to as a waypoint. A useful way to record this would be to assign a unique name to the position. That way, if you were to go to a new location you could use your receiver to guide you back to your current location.

The cursor is in the upper left corner, and the arrows displayed in the lower right corner of the screen indicate that it is in the edit mode. What you will do next is assign a name to this position.

The waypoint name can be created by the receiver or you can input a name that means something to you. If you press ENTER without creating a name, the receiver automatically assigns a waypoint name. Waypoint names assigned by the receiver appear in the format WPxxx, where the xxx is a sequential number (001, 002 etc.).

To allow the receiver to name the waypoint automatically, press ENTER. The following screen will appear briefly and then the receiver returns to the POSITION screen.

All waypoint names begin with an icon. You have the option of choosing one of nine different icons: a right flag ( ), a left flag ( ), a diamond ( ),

a double box( ), an anchor ( ), a square ( ), a diving symbol ( ), a fish ( ), or a target ( ). Unless you select a different icon, unit-generated

waypoint names use a pin ( ) icon. These icons will be used to display the relative location of the waypoint on the PLOT screen and the ROAD screen (described later).

Now you will save the same position as above, but this time you will assign a name to the waypoint.

Press ENTER, highlight SAVE POS and press ENTER again. Select an icon by pressing the UP or DOWN ARROW .

A little trick in scrolling quickly through the letters and numbers in the edit cursor is to hold down the UP or DOWN ARROW key. The characters scroll by every third character. When you are near the character you want, release the arrow key and step one character at a time.

Continue using the RIGHT ARROW to move the cursor and the UP/DOWN ARROWs until you have spelled out the word “DOCK” and your screen appears like the one shown. (Remember, your

Introduction to Routes

A route is a planned course of travel defined by a series of waypoints. To create a route, you select waypoints that you have stored in the receiver’s memory. These waypoints are then connected to form the segments or “legs” of the route. A route may contain from one to fifteen legs.

Suppose you were on a fishing trip in the area shown below. You want to go from the dock to the bait shop, then across to the inlet on the island. Before you start, turn the receiver on and let it get a position fix. Once you have a fix, save it as a waypoint. That way you’ll be able to create a route back to the dock at the end of the day, even if darkness or weather conditions (cloud cover, rain, etc.) make it difficult to use your own navigation skills.

In addition, you can instantly create a one-leg route called a GOTO. This route uses your present position as its start and any waypoint you select that you have saved in memory as the destination. The following will show you how simple it is to create a GOTO route. In this example we have stored a waypoint in memory and named it " JETTY."

If the receiver has not yet computed a position fix, then the start of the GOTO may not represent your current position. It will, however, correct the navigation information after a position fix is acquired.

Creating a GOTO Route

After computing a position fix, press GOTO. Use the UP/DOWN ARROWs to highlight the waypoint that represents your destination.

The first four selections in the GOTO menu allow you to create a Man OverBoard (MOB), Backtrack, or Coordinate route or to activate an existing route; they are discussed in the Reference Section.

Press ENTER. The receiver begins navigating toward the selected waypoint and the display returns to the last viewed NAV screen. Note that the destination is now placed in the header bar of the NAV screen.

It is necessary to have a current position fix in order for the receiver to compute navigation information. If you do not have a position fix, the navigation information will be displayed with dashes until a position fix is acquired.

Reference Section

This section explains the various functions of your receiver and is organized by function or topic rather than by menu. To perform a given function, refer to the Table of Contents and the Menu Cross Reference Guide in order to quickly locate that section.

General Usage

The receiver is used to compute coordinate positions which are stored as named waypoints and used to create routes. Waypoints can be viewed, edited, and projected to create new waypoints, or deleted. Routes can be created, activated, deactivated, reversed, edited and cleared. This section covers these and other functions which will enable you to take full advantage of your receiver’s capabilities.

Turning the Receiver On

POWER

Press the POWER key and hold for three seconds. If the batteries are installed correctly or the external power is properly connected, the copyright and Magellan displays will quickly flash on the screen, followed by the POSITION screen (if the unit has been initialized) or by the message UNIT IS NOT INITIALIZED PRESS ENTER TO INTIALIZE. (See section on First Time Use - Initializing the Receiver.")

If these screens do not appear, please check that the battery installation and/or external power is properly connected and turned on.

Turning the Receiver Off

POWER

To turn the receiver off, press the POWER key. The POWER DOWN screen is displayed for five seconds. Pressing the POWER key again before the counter reaches 1 will cause the receiver to turn off immediately; pressing any other key will stop the receiver from turning off.

Inputting Data

The UP/DOWN and LEFT/RIGHT ARROWs have two functions depending on how the ARROW ICONS are displayed in the bottom right corner of the various screens.

Moves the cursor

one space , left or

right

Scrolls through the

icons or

alphanumeric list

While on some screens the UP/DOWN or LEFT/RIGHT ARROWs are used to access additional pages, on other screens they allow you to input data, such as waypoint names or coordinates, or to select menu items.

The ARROW ICONS in the status line indicate which mode is currently being used. Whenever there are additional screens to view from the

one displayed, the receiver shows normal arrow icons ( ) in the lower right corner of the display. A second type of arrow may be displayed in the lower right hand corner. These arrows are similar to the first, but are displayed in reverse video ( ) and are referred to as “input” or “edit arrows.” When these reverse video arrow icons appear, the arrow keys are used to enter data or make selections on the current display, rather than to move from screen to screen.

Turning the Light ON and OFF

To activate the display light, press the LIGHT key. To deactivate the display light, press the LIGHT key again.

LIGHT

The receiver will indicate that the light is on with a light bulb icon ( ) in the status line next to the arrow icons.

The display light causes an increase in battery drain resulting in shorter battery life.

Brightness level can be adjusted (LOW/HIGH) in the SETUP MENU.

NAV Screens

The three NAV screens accessible from the NAV key are the POSITION, NAV 1 and NAV 2 screens. You may scroll through these screens using the

NAV key or the UP/DOWN ARROWs. Press NAV until the POSITION screen is displayed.

Viewing the POSITION Screen

The POSITION screen displays the coordinates and elevation of the current position in a larger format so that they may be easily viewed from a distance.

Viewing the NAV 1 Screen

Press the NAV key until the NAV 1 screen appears, showing BRG, DST, COG and SOG. NAV 1, the first navigation screen, provides you with information about your speed and direction of movement. If a route is active, the NAV 1 screen also tells you where you are in relation to the destination and courseline, and displays the name of the destination waypoint of the active leg in the title bar.

In the bottom corner of the NAV 1 screen is a CDI (course deviation indicator), which is a graphic representation of cross track error, or how far off course you are. The straight line is the course marker, and the current position is represented by the arrow. If the arrow is to the left of the course marker, you are to the left of the courseline. The number next to the CDI is the CDI scale, or the distance from the courseline at the center to either end of the CDI. Pressing the LEFT/RIGHT ARROWs changes the CDI scale. Select from 0.2, 0.4, 1.0, 2.0, 4.0 or 8.0 distance units.

WAYPOINTS

Saving a Position Fix as a Waypoint

During normal operation your receiver continuously computes your position and displays that information on the POSITION screen. Quite often you will want to store the position data for use later on. This stored fix is referred to as a waypoint. An obvious use would be to store the position where you are now with a unique name. That way if you were to go to a new location you could use your receiver to guide you back to your current location.

ROUTES

A route is a planned course of travel defined by a series of waypoints. To create a route, you must already have waypoints stored in the receiver’s memory. These waypoints are then connected to form the segments or “legs” of the route. A route may contain from one to fifteen legs.

Activating a GOTO Route

The GOTO function enables you to create a simple one-leg route from your present position to a defined waypoint. When a GOTO is active, the title bar of the NAV and PLOT screens display “TO Destination Waypoint” and the screens display the corresponding navigation information.

It is also possible to activate a GOTO from the PAN N SCAN feature on the PLOT screen as described earlier.

The receiver begins navigating toward the selected waypoint and the display returns to the last viewed NAV screen.

It is necessary to have a current position fix in order to correctly activate a GOTO. If you have a current position fix, the NAV screens will display navigation data, if not, the navigation data will be replaced by dashes.

If a route, GOTO, or MOB is already active, the new GOTO automatically replaces it and becomes the active route.

A GOTO always uses your current position as the starting point. If the unit has not yet computed a position fix, then the start of the GOTO may not represent your current position.

Accessing the Route Menu

The Route Menu is used to create and view up to five single or multileg routes. A pop-up menu allows you to activate, deactivate, or reverse a selected route, edit or view the legs of the route, or clear the route.

The ROUTE MENU can be accessed in three ways:

 Press MENU, use the UP/DOWN ARROWs to select ROUTE MENU in the FUNCTION MENU, and press ENTER.

Activating and Deactivating a Route

Only one route, MOB, BACKTRACK, COORD route or GOTO can be active (in use) at any time. When you set a MOB, GOTO or BACKTRACK route, any multileg route that you were using is automatically deactivated and replaced with the route you just set. Likewise, creating a multileg route makes that route the current active route, deactivating any other route.

The MOB position and MOB route information will be lost when the receiver is turned off.

Creating a Backtrack Route

This creates a route using fixes in the Last Fix Buffer (up to 16 of the most recent last fixes) to create a route that “backtracks” the course you last took. This way you could leave point A, travel for a couple of hours, set a backtrack route, and the receiver would guide you back to point A following the same course you just took.

GOTO ENTER

Use ARROW KEYS

to highlight

BCKTRK

Press GOTO, DOWN ARROW to highlight BCKTRK, and press ENTER. A backtrack is created in the first available route.

The display returns to the last viewed NAV screen and shows navigation information for the destination waypoint of the first leg of the BACKTRACK route.

If all five routes are full a message screen appears indicating that a route must be deleted in order to create a backtrack. (If this is the case, see Deleting a Route.)

Backtrack waypoints use an up arrow ( ) icon to indicate that they were created in backtrack. How many of these waypoints were created (up to 16) is determined by the number of fixes in your last fix buffer.

Creating a COORD Route

The COORD option allows you to create a one-leg route to a position not contained in the waypoint list, simply by providing its coordinates.

GOTO ENTER

Use ARROW KEYS

to highlight

COORD

Press GOTO, use the UP/DOWN ARROWs to highlight COORD and press ENTER.

The COORD screen appears. The cursor is on the leftmost character of the latitude field and the arrow icons indicate that the display is in edit mode. The position shown is the last position fix taken.

Edit the coordinates using the UP/DOWN ARROWs to scroll through and select numbers, and the LEFT/RIGHT ARROWs to move the cursor. At the rightmost position, the UP/DOWN ARROWs toggle between N/S and E/W if using LAT/LON coordinate system.

The receiver immediately begins navigating toward the selected coordinates. The display returns to the last viewed NAV screen and the words TO COORD appear in the title bar.

The COORD position and COORD route information will be lost when the receiver is turned off.

SETUP OPTIONS

Setup options allow you to customize your receiver to display information in the format that best suits your needs.

Initializing the Receiver

This option was discussed in more detail earlier, but, in general, INITIALIZE allows you to input the approximate coordinates, time, and date for your present position if the receiver has computed a position fix or if it has had its memory cleared. This function should also be used any time the unit is moved more than 300 miles with the unit turned off, to help the receiver acquire a fix faster.

ELEV MODE

Press ENTER

Use UP/DOWN

ARROWS to select

2D or 3D

ENTER

In addition to position, your receiver can compute your elevation when it is receiving signals from at least four satellites. This is referred to as “3D” Elevation Mode.

When there are only three satellites in view, the receiver cannot compute elevation though it can still compute your position. In this case the receiver will display the last computed elevation or the elevation that you manually enter in INITIALIZE. This elevation mode is referred to as “2D” (the default setting). You may select either elevation mode in this SETUP feature.

If you select the 2D elevation mode you will be prompted to input the elevation. If you are unsure of the elevation you can press ENTER to accept the previously used elevation.

If you select the 3D elevation mode, the receiver will calculate elevation whenever signals are being received from at least four satellites. When fewer satellites are being tracked, the receiver will default to 2D and display the 2D icon.

Selecting Time Display

Your Magellan receiver can display time in one of three formats: local 24-hour (military), local 12-hour (AM/PM), or UT (Universal Time or Zulu). The default Time Display is LOCAL AM/PM.

If the receiver does not have a computed position fix the receiver displays a warning to alert you that an initial time has not been set in INITIALIZE. After inputting an initial time you may change the format that time is displayed in.

Setting Velocity Averaging

As you are travelling with your receiver on you may notice fluctuations in the velocity displayed. Like elevation, velocity is very susceptible to Selective Availability. Velocity Averaging will minimize this effect by displaying an averaged speed measurement. You have three options to choose from: OFF (no averaging) would be used where you require rapid updates of velocity: 20 SECONDS would be selected where rapid updates of velocity are not essential, generally at fairly low velocities; or 60 SECONDS where immediate velocity information is relatively unimportant, such as a long journey at a constant speed. The default is OFF.

Inverted arrow icons in the lower right corner indicate that the ARROW keys are used to enter or edit information.

Non-inverted arrow icons indicate that there are other screens accessible from this screen using the ARROW keys.

Ü Poor Geometric Quality. Appears when the Geometric Quality

(GQ) of a position fix is below a set value and the accuracy of the position fix is questionable. Position information displayed may not be accurate enough to be used for navigation.

Ä Old Data. The Old Data icon (“hourglass”) appears when the

receiver has been unable to update the position fix. The position information displayed is that of the last position fix computed.

Position and navigation information displayed while the Poor Geometric Quality and Old Data icons are being displayed may be inaccurate and should not be used for navigation.

Ñ Low Signal Quality. Is displayed if the Signal Quality (SQ) of one

or more satellites used to compute a position fix drops below a minimum level. This has a minimal effect on accuracy, and is intended only to alert you that a signal may soon be lost.

Ç Two Dimensional. The 2D icon indicates that the receiver is not

receiving signals from at least four satellites to compute elevation information. The 2D icon is also displayed when you have selected 2D in the ELEV. MODE portion of Setup.

Light On. Indicates that the display light is on. Simulator . Indicates that the simulator function is activated.

D Differential. Indicates that the unit is receiving differential

information.

LOW BAT Battery Warning. This is warning you that you need to

replace the batteries very soon or risk losing stored data.

Troubleshooting

are they oriented correctly? The batteries may also have run down completely.

If operating from external power, the receiver may not have been hooked up correctly, or the external power source is not operating. Check the connections, and be sure the external power source is operating correctly.

position fix If the old data icon (Ä) is displayed, the signal from doesn’t change one or more satellites has been lost, and the receiver

has been unable to reacquire or replace it. The displayed fix is at least 10 seconds old, and should not be used for navigation.

If there is no old data icon, the display may be frozen. Press any key to change the display. If the display does not changed, refer to “frozen display.”

position fix Small changes in the position coordinates and fluctuates elevation are normal. They are caused by several

variables, including the geometric quality of the fix and the effects of SA. Geometric quality is a measurement of the probable accuracy of a fix based on the position of the satellites being used in relation to each other.

NMEA device is The receiver may be outputting an NMEA data not responding message that is not compatible with the NMEA

device; check the message format selected with SETUP. Also check the connection between the receiver and the device, and be sure the device is on. If supporting an autopilot, be sure that a route has been set and activated.

How to Contact Customer Service

The list above should allow you to solve most of the operating problems you are likely to encounter. Simply disconnecting the unit from power for a moment may solve your problem. If this does not help, try clearing the receiver's memory in the Setup Menu and reinitializing your receiver.

Abbreviations and Data Terms

EXPLANATION OF DATA TERMS

BRG. Bearing is the direction, as measured in degrees from north in a clockwise direction. The receiver uses either true north or magnetic north, as selected in the Setup Menu. The illustration shows

135°

COG. Course over ground is the direction of movement expressed as bearing. If a boat is pointing exactly north (0°) and there are no other factors affecting its travel, the COG would be 0° but that is rarely the case. Water currents and wind can affect the course the boat is taking.

If there is a current passing from left to right across the boat (90°) the COG would change even though the bow of the boat is still pointing north. COG is measured in degrees with North being 0°.

CTS. The optimum direction the vessel should be steered in order to efficiently make headway back to the courseline while also proceeding toward the destination waypoint. It is a "compromise" course bearng that projects from your current position to a point on the courseline mid-way between a point perpendicular to your position and the current leg destination waypoint.

DST. Distance to go to an active waypoint, or the distance between two waypoints in a route leg.

ETA. Estimated time to arrival.

SOA. Understanding speed of advance is a little tricky but once you do it

becomes fairly simple. For this example we will use an exaggerated sample so as to clearly describe SOA.

The boat is heading towards the buoy and is currently at point A. If the boat had followed its original course (A1 – buoy), it would be somewhere on the

line A1 — B1. (The XTE for this sample is the distance between points A and A1.) In 1 hour he is at point B and has travelled 34 NM (equivalent to a speed of 34 knots).

Now if you project downwards to the course he should be on, you arrive at point B1.

Comparing the lines from points A and B and from points A1 and B1 you see that while the boat travelled 34 NM it only moved 30 NM along the courseline. If he moves 30 NM on the courseline in 1 hour, his SOA is 30 knots, whereas SOG would be 34 knots.

SOG. Speed over ground is the speed at which the vehicle/vessel is moving in respect to the earth. SOG is sometimes referred to as ground speed and is measured in knots, miles per hour, and kilometers per hour. (This is not the same as speed through water.)

STR. The difference between COG and BRG. If BRG is180° and COG is 183°, then STR is 3° Left.

TTG. Time to go to the active waypoint. VMG. Velocity made good is the portion of the velocity that is in the direction

of the destination. In the above example, the boat is travelling directly towards the buoy even though not on the courseline originally set. In this case, all of this velocity is being applied towards arriving at the destination, (i.e., VMG = SOG). Should the boat veer away from this course and travel in a line parallel to the original courseline (A1;B1) he would be travelling on a course that would not intercept the buoy waypoint. As the boat moved along, less and less of his velocity would be applied toward arriving at the buoy. By the time point D is reached, none of the velocity is applied to getting closer to the buoy and the VMG would be 0. As he moves to point E, he is moving away from the buoy and his VMG is a negative value.

Courseline

XTE. XTE (cross track error) is the distance to the left or right of the courseline that you are travelling. As you will see in the discussion of other data items, XTE is important in computing them accurately.

Keeping XTE at a minimum will help maintain the most direct route to your destination. This illustration shows a boat and the courseline. The arrows between the boat and the courseline is the distance of XTE that this boat is to the left of the courseline. This boater would need to steer right to close the XTE.

Coordinate Systems

Positions are locations that are described in a unique way so that one locations cannot be confused with another. This is done by using a coordinate system to describe locations. Your Magellan receiver has the ability to use any one of four different coordinates systems; LAT/LON (latitude and longitude), TD (Time Difference of Arrival), UTM (Universal Transverse Mercator), and OSGB. The one you select (in SETUP) will be determined by the maps and charts you use; you would generally want the receiver to display position coordinates in the same system that is used by your maps.

LAT/LON Coordinate System. LAT/LON is the most commonly used coordinate system today. It projects lines of latitude (parallels) and lines of longitude (meridians) onto the earth’s surface. Lines of latitude are the equator and the horizontal lines that are parallel to it. Lines of longitude are the vertical lines that are perpendicular to the equator and pass through the poles. A position is described as being the intersection of a line of latitude and a line of longitude.

Specifically, a position is so many degrees north or south of the equator (up to the poles, which are 90˚N and 90˚S; the equator is 0˚ latitude), and so many degrees east or west of the Prime Meridian, which is 0˚ longitude. (The Prime Meridian passes through Greenwich, England.) Parts of a degree are minutes; there are 60 minutes (written as 60') to a degree. Minutes can also be divided into smaller units. Fractions of a minute can be expressed as decimals or as seconds. (There are 60 seconds to one minute, written as 60"). So a Lat/Lon position coordinate can be expressed in two ways, which your Magellan GPS receiver displays as 25°47.50 or 25°47’30.

UTM Coordinate System. Another commonly used coordinate system is UTM (Universal Transverse Mercator), which is generally found on landbased maps and quad sheets that are produced by government map providers. On land, you may find that UTM coordinates are easier to use than Lat/Lon.

UTM coordinates are easy to use, but since the model it is based on is somewhat abstract, this section is a very simplified introduction to UTM.

Instead of projecting an imaginary grid of intersecting lines onto the globe, UTM projects sections of the globe onto a flat surface. Each of these sections is called a “zone.” There are 60 zones to cover the entire earth between 84˚N and 80˚S (polar areas are not described by UTM). Each zone is 6˚ wide as projected from the earth’s center.

A UTM position is described by three elements; the zone it is in, the easting, and the northing. Eastings and northings measure how far into a zone a position is in meters. Eastings are an east/west measurement, and correspond roughly to longitude. Northings are a north/south measurement, and correspond to latitude.

This chart shows the position of Magellan Systems described in both Lat/ Lon and UTM coordinates.

TD Coordinate System. TDs are indicated on many nautical charts in addition to the LAT/LON marks. They are established lines of position (LOPs) that are determined by the difference in the length of time required to receive Loran-C signals. Many coastal navigators use TDs because Loran is a familiar radio aid navigation and TDs are clearly marked on their charts. The Meridian XL can display position coordinates in TDs by converting from position fixes calculated in Lat/Lon. (No measurements are made using the Loran signals.)

To use TDs, the Loran receiver is set to a specific chain of stations; each Loran chain consists of one master station (designated as M) and two or more secondary stations (W, X, Y, and Z). Next, the navigator determines which two secondary stations will provide the most accurate position fix based on the angle of intersection of the LOPs. The TD measurement is the difference between the time it takes a signal to arrive from the master station and the time it takes to arrive from a secondary station to your location. This is referred to as a TD. Two TDs are required for a position fix.

The Meridian XL displays position coordinates in TDs by converting the LAT/LON coordinates to TDs, mathematically, using the GRI (chain number) and secondary beacons you entered when selecting the TD coordinate system.

When TD is selected in Setup under COORD SYS you will be asked to select the following

1) The GRI (also called the chain) that you will be navigating in.

2) The two secondary stations that will provide you with the best angle of LOP intersections. If you have used Loran in the past, you should simply enter the values that you have used before.

Other Coordinate Systems. OSGB coordinates are similar to UTMs, but they describe only Great Britain. They must be used with the GBR36 datum, which also describes Great Britain. This coordinate system cannot be used in any other part of the world. The Meridian XL automatically selects the GBR36 datum when the OSGB coordinate system is selected in Setup. (While OSGB coordinates must be used with the GBR36 datum, the GBR36 datum can be used with LAT/LON coordinates; just be sure the map you are using uses both LAT/LON and GBR36.)

If you select OSGB in the COORD. SYS. portion of the Setup Menu be sure to change the map datum back to the one you will be using (WGS84 is the default) when changing to another coordinate system.

Irish Grid uses the Ireland datum, Swedish Grid uses the RT90 datum, Swiss Grid uses the Swiss datum and Finnish Grid uses KKJ datum.

General Maintenance

Meridian XL

The Meridian XL is powered by three AA batteries. It can also be powered from an external DC power source by using the optional Power/Data Cable.

Batteries

We suggest using AA alkaline batteries to power the receiver. (Magellan Systems recommends Eveready Energizer™ batteries.) Alkaline batteries will power the receiver for 6 hours or more of continuous operation.

To install the batteries, hold the receiver as shown in the illustration at the right. At the same time, press down slightly on the battery compartment cover and pull the cover toward you. Insert batteries as indicated in the compartment and replace the cover.

When the battery power level drops, a warning message will appear on all displays (LOW BATT). The receiver should still have sufficient power to operate for up to 30 minutes if alkaline batteries are being used.

When the batteries no longer hold enough power to operate the receiver, the receiver turns itself off. The batteries will still be able to maintain the memory for a time, but the receiver can be operated only if external power is supplied or if fresh batteries are installed.

Batteries are not recharged in the receiver. The low battery warning appears approximately 10 minutes before the receiver automatically powers down to preserve memory. When batteries are changed, you have 15 to 20 minutes to install fresh batteries without losing memory.

It is possible to use rechargeable batteries, but there are a couple of things you should be aware of when using them. Commercially available NiCad batteries typically have poor power performance after repeated use, and rechargeable alkaline batteries maintain only 50% of the useful life of standard alkaline batteries. Rechargeables also have a very sudden power drop at the end of their charge. The drop may be so sudden that the battery warning is not displayed, although memory can be maintained for a while.

External Power

The Meridian XL can also be operated from an external DC power source. This requires the Power/Data Cable that is included with the optional mounting kit. (Even when operating from external power, the receiver must have batteries; the batteries will be used to maintain memory when the receiver is off.)

The cable converts DC power to a level usable by the receiver. It also can be used to output positioning data to electronic navigation equipment that conforms to NMEA standards, and to import broadcast differential corrections from a differential beacon receiver.

The use of a non-Magellan cable or an altered Magellan cable may damage the receiver and will void the warranty.

Antenna

The receiver has an attached quadrifilar antenna, which rotates 360˚. Using the extension cable and suction cup provided with the optional Mounting Kit, the antenna can also be detached from the receiver and temporarily mounted to any convenient surface. (The antenna is detached by rotating it until its base is parallel with the display, then pulling it away from the receiver.) Since it can be used detached from the receiver, the antenna can be placed wherever it has the clearest view of the sky.

In order to provide the best signal reception possible, the antenna must be vertical. If attached to the receiver, rotate the antenna from its storage position to the upright position. If detached from the receiver, the antenna should be mounted as vertically as possible with the connecting cable at the bottom.

GPS signals will pass through glass and canvas (such as bimini tops) however, you may experience some signal loss in areas of heavy foliage. (Do not stand under a tree in full leaf when attempting to take a fix.) Signals will not go through metal, and you are unlikely to obtain signals in a permanent structure.

Signals can be temporarily blocked by trees, masts, and people. If you are unable to obtain satellite signals when out of doors, try moving slightly to get a better view of the sky. If the receiver is being operated in a covered location (such as a navigation station), you may want to use the optional External Antenna Kit. (Use only a Magellan antenna; the use of a nonMagellan antenna may greatly degrade the performance of the receiver.)

What Is GPS?

GPS is a constellation of navigation satellites that orbit the earth. The precise time and position information transmitted by these satellites is used by a GPS receiver to triangulate a position fix.

The system is now officially declared “initial operational,” and provides continuous, 24-hour 3D (position plus elevation) coverage anywhere on the earth.

GPS was developed by the United States Department of Defense to provide consistent, reliable navigation information that is unaffected by rough terrain and bad weather, and is highly resistant to multipath errors and interference. The DoD continues to administer and control the Global Positioning System.

Although GPS was developed as a military navigation system, its civilian and commercial uses were recognized. The satellites therefore transmit two codes, a military-only encrypted code (PPS) and a civilian-access, Standard Positioning Service (SPS) code. All commercial and consumer GPS receivers are SPS receivers.

How Does GPS Work?

Each GPS satellite transmits its precise location (position and elevation) and the start time of the transmission. A GPS receiver acquires the signal, then measures the interval between transmission and receipt of the signal to determine the distance between the receiver and the satellite: this is ranging. Once the receiver has computed range for at least three satellites, its location on the surface of the earth can be determined.

Each satellite transmits two types of data, almanac and ephemeris. Almanac data is general information on the location and health of each satellite in the constellation. Since it contains general information, an almanac can be collected from any satellite. A receiver with a current almanac in its memory knows where in the sky to look for satellites, given its last known position and the time of day. Ephemeris data is the precise satellite positioning information that is used for ranging. Each satellite transmits its own ephemeris data.

Both almanac and ephemeris data are required for a GPS receiver to locate and acquire satellites quickly and compute a position fix.

Accuracy

GPS positioning with an SPS receiver that is intended for general use will produce accuracies of 25 meters or better.

In fact, SPS receivers have proven to be far more accurate than anyone anticipated. DoD has decided that 25-meter accuracy is a potential risk, and has introduced Selective Availability (SA) to maintain a military advantage. SA is a random error that is introduced to the SPS code ephemeris data and reduces the accuracy of any SPS receiver. The size of the error changes, but rarely exceeds 100 meters.

The DoD civil GPS user policy is that GPS accuracy as affected by SA is sufficient for general navigation. In an open environment, it usually is. Even with SA, a GPS receiver will bring you within visual range of a destination or target, and GPS remains the best available source of accurate, repeatable navigation and positioning information.

If you feel that you really need 25-meter accuracy, the effects of SA can be overcome with a technique called broadcast differential to produce highly accurate position fixes.

DGPS

Differential GPS (DGPS) computes the size of the error and applies it to positioning information. There are several ways to perform DGPS, one of which is broadcast differential. Broadcast differential uses GPS receivers at control sites to measure the range errors for all visible satellites and determines a correction for each satellite. These corrections are broadcast in the RTCM SC-104 format by a radio beacon at the control site to any differential beacon receiver that is within range of the signal.

The differential beacon receiver receives and demodulates the signal, then relays it to the user’s differential-ready GPS receiver. The user’s GPS receiver applies the corrections to the positioning information it collects to compute differentially corrected position and navigation data.

This technique requires that your GPS receiver be connected to a compatible differential beacon receiver (such as the Magellan DBR™, which is compatible will all differential-ready Magellan receivers). You must also be within range of a differential radio beacon.

More Information on GPS

There are many sources for more information on GPS and navigation. The sources listed here are just a few of the books, magazines, and Internet addresses that deal with GPS. Your local library is a good source for technical books on GPS and navigation.

GPS Information Center

The GPS Information Center provides general information on the Global Positioning System and satellite status. This center is operated by U.S. Coast Guard for the Department of Transportation, and was established to provide information and to serve as a point of contact for civilian GPS users.

A Comprehensive Guide to Land Navigation with GPS

An excellent book written by Noel J. Hotchkiss and published by Alexis Publishing. ISBN No: 0-9641273-2-6. This book uses the Magellan Trailblazer to discuss and describe land navigation with a GPS receiver. The book is very easy to read and gets into detail the art of navigating with GPS. (Available from Navtech Seminars.)

Glossary

Active Leg The segment of a route currently being travelled.

Azimuth The angular measurement from the horizon to a satellite

or other object.

Backtrack Retraces the position fixes (up to 21) stored automatically

by the receiver every 10 minutes.

Bearing The compass direction from your position to a destination,

measured to the nearest degree.

Coordinates A unique numeric or alphanumeric description of position.

Course The direction in degrees from the start waypoint of a

course line to its destination.

CTS The optimum direction the vessel should be steered in order

to efficiently make headway back to the courseline while also proceeding toward the destination waypoint. It is a “compromise” course bearing that projects from your current position to a point on the courseline mid-way between a point perpendicular to your position and the current leg destination waypoint.

Datum Refers to the theoretical mathematical model of the earth’s

sea level surface. Map makers may use a different model to chart their maps from so positions will differ from one datum to another. The datum for the map you are using can be found in the legend of the map.

Elevation Distance above or below mean sea level.

EPE Estimated Position Error is the approximate error (between

0 and X) introduced in the ephemeris signal by the U.S. Department of Defense for reasons of security. This random error, known as Selective Availability (SA) is not due to receiver error and is not significant enough to affect navigation for most purposes (See DGPS in appendix).

ETA Estimated Time to Arrival is the approximate time it will take

to reach the destination from the current position based on VMG.

Geometric Measures the probable accuracy of a position fix, based on Quality the position of the satellites relative to each other.

GOTO A single leg route with the present position being the start

of the route and a defined waypoint as the destination. (If the unit has been moved while turned off and has not yet acquired a new position fix, the start of the GOTO will be the position fix last recorded.)

Heading The direction in which the receiver is moving, track or

ground course, (due to wind, current, and so forth), and may also be different from the course.

LAT/LON Coordinate system using latitude and longitude coordi-

nates to define a position on the earth.

Latitude The angular distance north or south of the equator

measured by lines encircling the earth parallel to the equator in degrees from 0° to 90°.

Last Fix Position coordinates computed and stored automatically

every 10 minutes in the Last Fix Buffer.

Last Fix Buffer The list of the most recent last fixes automatically stored by

the receiver. (Up to 21 may be stored at one time.)

Leg (Route) A segment of a route that has a starting (FROM) waypoint

and a destination (TO) waypoint. A route may consist of 1 or more legs. For a route that is from waypoint A to waypoint B, waypoint B to waypoint C, and waypoint point C to waypoint D has three legs with the first leg being from waypoint A to waypoint B.

Longitude The angular distance east or west of the prime meridian

(Greenwich meridian) as measured by lines perpendicular to the parallels and converging at the poles from 0° to 180°.

Magnetic The direction toward the north magnetic pole from the North observer’s position.

OSGB A coordinate system describing only Great Britain, similar

to UTMs. Generally used with GBR36 datum, which also describes only Great Britain. This coordinate system cannot be used in any other part of the world. The Meridian XL automatically selects the GBR36 datum when the OSGB coordinate system is selected in Setup. (While OSGB coordinates must be used with the GBR36 datum, the GBR36 datum can be used with LAT/LON coordinates; just be sure the map you are using uses both LAT/LON and GBR36.)

Position Fix Position coordinates as computed by the receiver.

Reverse Route Duplicates an existing route but in reverse order.

Route A planned course of travel that is defined by a sequence of

waypoints. When active, the route is used in the calculation of all navigation data except position, speed over ground and track/course over ground.

Start and Destination Waypoint (FROM/TO) Waypoints that mark the

beginning and ending of a leg of a route.

TDs Coordinate system using lines of position determined by

the Loran-C signals. Many coastal navigators use TDs because Loran is a familiar radio aid navigation and TDs are clearly marked on their charts. Your Magellan receiver can display position coordinates in TDs by converting from LAT/LON.

Time To Go The estimated time for the receiver to reach the destina-

tion from its current position based on the current VMG.

True North The direction to the geographical North Pole from an

observer’s position. The north direction on any geographi- cal meridian.

Track The actual path travelled, which may differ from the

planned course.

Track History The track over a selected length of time.

UT Universal Time, formerly referred to as Greenwich Mean

Time (GMT).

UTM Universal Transverse Mercator (UTM) metric grid system

used on most large and intermediate scale land topographic charts and maps.

VMG Velocity Made Good. The component of the velocity that

is in the direction of the destination.

Waypoint A location saved in the unit’s memory which is obtained by

entering data, editing data, calculating data or saving a current position. Used to create routes.
