Scope Of This ManualThis manual reflects the software capabilities in version 1.5 software.

We have attempted to take care and develop manuals which providein-depth information. Where possible, we have attempted not only todescribe what you see on the screen, but how to understand and useit as well. Obviously, we can't teach you how to navigate, but we canhelp make your work,more thorough and enjoyable. Throughout themanual, you will find helpful hints about the interaction of variousfunctions. In a piece of equipment that has the many capabilities ofthis receiver, important details can sometimes become obscured in oneOr two lines oftext. In our effort to ensure you get the most out ofthisdocumentation, and to protect against important details becoming lost,don't be surprised ifyou see the same or similar information more thanonce.

This manual is organized by describing first the various MX420 mod-els covered in this book. Then:the special front panel features includ-ing the traffic light indicator. The sections that follow detail each pri-mary functionas it is presented on the front panel (i.e. NAV, RTE, WPT,PLOT, ...CFG). The appedixes describe important details about specialfunctions.

Appendix-A is a special section describing the AlS displays and set-ups of the MX420/AIS model.

We hope you find the manual enjoyable and informative reading. Asalways, we welcome your comments on improving our products ormanuals. We wouldn't mind ifyou wrote to tell us that we did the jobright the first time either. You can find a Reader Comment Card at theback of the manual.

About GPS Navigation

About GPS NavigationOperator's Manual

Version 7.5

This GPS receiver is a precision navigation instrument utilizing thelatest technology available today to provide optimum performance

. from the GPS satellite and Beacon land signals received. As with allother forms of radio signals, the ultimate navigation result is depen-dent upon the quality of these signals. Radio signals may, on occa-sion; be distorted, jammed, or otherwise incorrect. As a result, yourpositionaccuracy may occasionally be less than that which can nor-mally be expected. -

The Navstar Global Positioning System, commonly referred to as GPS,is a satellite navigation system developed by the V.S. Department ofDefense to provide both military and civilian users with highly accu-rate, worldwide, three dimensional navigation and time. By receivingsignals from orbiting GPS satellites, authorized users are able to con-tinuously navigate with an accuracy on the order of 16 meters or bet-ter, while civilian users are limited to accuracy's of approximately 30meters 2D RMS.

A technique referred to as Differential GPS (DGPS), allows users toobtain maximum accuracy from the GPS system. DGPS requires the useoftwo GPS receivers. One receiver, known as theRe/erence Station, isplaced at a surveyed location, the coordinates of which are preciselyknown. The purpose ofthe differential GPS system is to use the refer-ence station to measure the errors in the GPS signals and to computecorrections to remove the errors. The corrections are then communi-cated in real-time to the navigators, where they are combined with thesatellite signals received by the navigators, thereby improving theirnavigation or positioning. The geographic validity of these correc-tions decreases with distance from the reference station, but the cor-rections are valid for navigators hundreds ofkilometers fromthe refer-ence station.

Marine radio beacons operating in the 283.5 to 325.0 KHz frequencyrange are in widespread use for direction finding in coastal navigation.Because the beacon system has been in place and widely used formany years, it provides an effective means for the transmission ofDGPS signals. Depending on their local environment and power out-put, their signals may be usable to several hundred miles. Marine bea-cons provide an economical means of obtaining DGPS accuracy forcoastal navigators. GPS receivers with built-in beacon receivers aredesigned to provide low cost reception of DGPS corrections broad-cast (normally free of charge) by coastal authorities.

Special NotesGPS

About GPS Navigation

Never rely solely on any single navigational aid. Always use whateverinformation is available, and cross-check information when possible.GPS expected position accuracy is better than 30 meters (95% of thetime) but may be up to 100 meters occasionally. The derived speed andcourse readings may be hampered accordingly. The GPS system wasdeclared operational in 1994; however, the system's availability andaccuracy are subject to change at the discretion ofthe US Departmentof Defense.

OGPSThis GPS receiver's position accuracy is improved to 5 meters or betterfor 95% ofthe time, subject to the availability, accuracy, and control Ofthe DGPS correction transmission from the Beacon Station, or otherreference station connected at the time ofusage.

The differential GPS position is that ofthe navigator GPS antenna, andnot that ofthe beacon antenna, ifa separate beacon antenna is in use.In addition, the beacon radio signal which carries the DGPS correc-tions may be hampered by weather conditions such as heavy rain,snow, and thunder storms. The beacon radio signal may also be inter-rupted by powerful radio transmitters operating in long wavelengthbands.

Charts and Navigational AidsPositions obtained from charts are not always as accurate as yournavigator (due to environmental changes, the dates of charts, anddatum offsets if the datum differs from the one in use by the naviga-tor). The position of a floating aid can differ due to tide. set and drift.

Thesetwo MX420/8 units are connected in dual-control configuration butthey operate as independent navigator units with dedicated MX42lBantennas. The Integrity Monitor (IM) feature is a software option thatworks only in the MX420/8 CDUhardware.

This configuration allows data to be shared between two remotelyseparated stations (i.e. navigator's station and helmsman's station),with independent access to various information fields. The purpose ofthis configuration is to enable each CDU to calculate its own position,then check the operational status of the other GPS receiver. The GPSreceiver with the best overall operational status then provides thesystem position. This provides a fully redundant system, with self-recovery capabilities. The Integrity Monitor function can be set toAutomatic switch over, forced to the Master unit, or forced to theSlave unit for position and navigation functions.

DGPS Beacon SystemKeypad & Display Description

As Maritime Safety Administrations, Navy, and Coast Guard Organi-zations realize the limitations ofstandard GPS positioning, many havebegun installing DGPS Beacon Stations. While an understanding ofthis system is not necessary for operating receivers with internal bea-con receivers, you may want to read on to have a better understandingof how your receiver is capable of achieving the high levels of accu-racy made possible by this network of transmitters.

The DGPS Beacon System is comprised of three segments: the refer-ence station, Integrity Monitor (IM) equipment located at the beaconsite, and the Navigator equipment located on board the user's boat orvehicle. The DGPS beacon system design is illustrated below.

In addition,the MOB position is displayed in the upper left corner, so that youcan quickly read the coordinates to others who may be availableto render assistance. This plot screen also provides the vital bear-ing and distance back to the MOB position, as well as your presentcourse over ground.

~ The MOB position, date and time are stored in the Waypoint Bankfor future reference (e.g. log book entries).~ Navigation data output on the NMEA ports (i.e. BWe and BWR),

are changed to reflect the current crisis situation. This way, otherinterfaced equipment can also help guide you back to the MOBposition. When the MOB condition is canceled via a MOB screensoftkey, the NMEA sentences will automatically revert to the ac-tive route information. Don't forget to cancel the MOB so yourinterfaced equipment will read the correct data!~ The MOB function key and remote MOB input are disabled from

subsequent activation, until theMOB Cancel softkey is selected.

~ Other functions such as Position and Navigate can still be ac-cessed; however, the screen will revert to the MOB Plot screenafter 30 seconds. Bearing and distance information in these otherscreens relate to the MOB position, not the next waypoint in theactive route, until MOB is canceled.

To cancel a MOB condition, make sure you are in the MOB Plot screen.Press the Efunction key, then select the Cancel MOB softkey.

This MX420 receiver is also capable ofperforming the MOB functionfrom a remote contact closure. If the contact closure is made for lessthan 2 seconds, the input is registered as a Mark Position. If the con-tact closure is made for more than 2 seconds, the input is registered as

o f(EDIT)This function key activates or deactivates the softkeys and edit fieldswithin any screen where editing is appropriate. You will quickly learnthat this is an important operating feature in the unit. Press the E keywhen you want to start editing a screen and again when you havefinished editing. If after editing.you press a function key and nothingseems to happen, check to make sure you didn't accidentally alteryour information and press the Ekey to end editing. Most edit screensprovides an Escape softkey. If you decide for some reason that youdon't want to use the changes you have made, pressing the Escapesoftkey will restore the original information. However, once you pressthe Ekey, all changes are accepted and the originaldata is lost.

G C(CLfAR)This function key is probably the least used of all the function keys;however, it can save you some otherwise frustrating editing time. Thiskey allows you to erase or clear one character at a time. If you hold itdown, it will erase the entire line that the cursor is currently on.

o CURSORThis function key is the most used ofall the function keys. As its namesuggests, this key is used to move between edit fields. It also allowsyou to move between function screen pages (by pressing left or right).In addition, many of the edit fields allow you to use either the cursorkey or the Change softkey to scroll through or select from predeter-mined choices.

when you are in the edit mode. You will find that they are most oftenused in the RTF., WPT, and CFG screens, but they are used in otherscreens as well. If you are tryingto enter text, simply locate the desiredletter and press the appropriate key repeatedly until the appropriateletter or number appears. Ifyou accidentally go past the desired letter,repeat pressing the key and the .Ietter will come up again. You can

. toggle between upper and lower case characters by pressing the keyfor a long period.

You will also find that some screens allow you to input symbols intothe text fields. These symbols are selected through a softkey selectionwhere symbols are allowed. Don '1forget to press the 'E' key to get outofthe edit mode!Another helpful feature on this CDU is that successive depressionson the function key (when not in the edit mode) allow you to pagethrough all of the screens available for that particular function. Youcan accomplish the same thing by selecting a function and using theleft and right arrows on the cursor key (which is sometimes faster).Whichever method you choose, it is impossible to get lost betweenfunction screens. In addition, the software remembers which screenyou used last for each function. Each time you reenter a function (e.g.you go from PLOT to NAV), you will enter the last screen you viewedfor that function. You can change this setting in theCFG1 Operation.

Use the associated function key to access the international characterdesired (i.e. A for ). The international characters supported are:

ABC = A, A, .lE, A, cDEF=E,E

GHI= jMNO=N,6,6STU=U, D

Use the CFGkey when in the edit mode to cycle through these otheroptional characters.

There are four basic NAV screens. NAV4 only provides data if appro-priate sensors (e.g. wind speed/direction logs, NMEA compass, etc.)are interfaced and activated on the COD. TheNAVfunctions are highlyinteractive with the R1El screen, and a number of CFG menu selec-tions.

The RTEl screen provides the active route for the NAV screens. Italso maintains a waypoint pass log for you. One other important fea-ture in the R1El screen that you need to be aware ofis that the up anddown arrow softkeys control which waypoints are skipped (down ar-row) andwhich are restored (up arrow) for your current route. The ETAinformation is configured in the RTE I screen. Refer to the Route sec-tion of the manual for a full description.

The following CFG menus directly impact the NAV functions:

~ COG SOG - sets the filtering time for the displayed values.

~ Datum - sets the reference datum for your present position andwaypoints in the active route.

~ GPS Offset - sets an offset for calculating the GPS antenna posi-tion ifyou can't physically locate the antenna exactly where youwant it (e.g. over the centerIine of the boat).~ Navigation - sets a variety of important functions and alarms

~ Rhumb line or Great Circle navigation~ Range units: nautical miles, nautical miles and meters

(when under 1000 meters), nautical miles and feet (whenunder 1000feet), statute miles, statute miles and meters(when under 1000 meters), statute miles and feet (whenunder 1000 feet), kilometers, or kilometers and meters(when under 1000 meters)~ Cross-track error limit and alarm control~ Waypoint pass criterion and distance: bisector line, per-

pendicular line, complex (combination of bisector lineand perpendicular line), distance to waypoint, or manual~ Waypoint Approach distance~ Autopilot alarm control

~ Position - sets 20 or 3D mode, antenna height, Lat/Lon, Loran or

Version 7.5 77

Operator's Manual NavigateUTM, and some alarm limits. There is an optional software pack-age available to setup a user grid as well. The option is explainedin the Position, and CFG Position sections ofthis manual.

~ Time - sets appropriate offsets, and 12 or 24 hour clock mode.~ Various NMEA input controls for sensors (i.e. speed log, wind

instruments, etc).You have probably already figured out that you will need to pay closeattention to the configuration screens. The good news is that youshould only have to setup one time. Keep in mind, though, that youmay need to revisit these and other configuration screens from time totime to get the COU to do exactly what you want it to.

Dead ReckoningThe MX420 COU is capable ofDead Reckoning (OR) calculation whenappropriate compass/heading and speed log sensors are connectedand activated. Refer to the NAV4 and CFG sections ofthis document.

When the COU is in the OR mode a OR icon is displayed in the upperleft portion of the screen.

NA V7 - The Panorama ScreenThis screen is designed to give you a unique 3 dimensional look at theactive route you are to follow. It is typically referred to as a runwayview because you can see navigation markers, your course line, thecross-track error lines, and waypoint flags as you pass them. Take alook at the examplebelow.

will need to create a route in RTEl first "

The somewhat triangular shape at the bottom center of the screen"" represents the bow ofthe boat. Icons on the screen are always related

to this object. The two dash lines extending from the bottom of thescreen towards the center of the screen" represent your cross-trackerror limits. The dotted line extending from the bow of the boat iconrepresents your course line. The course line changes direction at theflags, which represent your waypoints, and continues through to theend of the active route you entered in RTEl. Notice that the cross-track error lines end at the first flag. As you pass the flag and start thenext leg ofyour course, these lines will be redrawn to reflect the coursechange. Icons that you seeleft and right ofyour course are navigationmarkers that you defme in the Waypoint Bank (WPTl) where a sym-bol is used as the first character of the waypoint description. ThePanorama and Plot screens will automatically place these navigationmarkers on the screen as you approach them.

The degree values that you see are your Course Over Ground (COG),as calculated by the GPS receiver's position fix to position fix, andBearing (BRG) from your present position to the waypoint. The speedvalue is your Speed Over Ground (SOG) as calculated by the GPS. Thedistance value displayed as the Range (RNG) is calculated from yourpresent position to the waypoint. The Time-To-Go (TTG) is the calcu-lated time it will take you toreach the waypoint, based on your WaypointClosure Velocity (see NAV4 description).To keep the screen from jumping around when you are stopped, thescreen freezes the graphic representation when your speed is under0.5Kn in DGPSmode or 2.0Kn in GPS mode. Once you get underway,your course details will update appropriately.

You will see a RL or GC symbol in the upper right corner ofthe displayindicating whether you are navigating under Rhumb Line or GreatCircle. This is set in the CFGNavigate menu.

In the bottom halfof the window, the vertical line in the center repre-sents your course line. The checkered area on the left and right side ofthis area represents the out ofbounds or beyond the cross-track errorlimit area. Whenever the boat is left Of right of the course line, thecorresponding checkered area changes to solid black, indicating theside of the course line that you are on. The number next to the courseline is your calculated cross-track error. The numbers in the lower leftand right hand corners indicate the cross-track limit you set in theCFGl menu under Navigation. You will notice that the cross-trackerror limit lines are slanted, just as they were in the Panorama screen.So if the boat is off to the right of the course, and the bow is pointingstraight up, you are actually tra veling away from the course line. Keepthe bow pointed toward the top of the course line, and you should beable to maintain your course without a lot ofdrift. The BRG and COGvalues will confirm this for you, when executed properly.

The window on the top leftprovides details relating to the True Wind Angle (TWA), True WindSpeed (TWS) and True Wind Direction (TWD), which are taken fromthe NMEA 0183 record of MWV or VWR. If the wind information isgiven in relative terms, the CDU calculates true values using availableGPS course and speed information to make the necessary adjustments.Refer to the Glossary for definitions on Apparent/True Wind Angle/Speed/Direction. To the right of the wind information is your VelocityMade Good (VMG) towards the waypoint. The VMG data is filteredtoshow the average speed from the last waypoint to your present posi-tion towards the next waypoint.

Navigate Operator's Manual

The window below the wind data provides information relating to yourcourse and speed. You will find the Course Over Ground(COG calcu-lated by the MX421 smart GPS antenna), Heading (HDG,yourNMEA0183 compass input), andHeading ToSteer (HTS) data on the left sideof the window. HTS data is calculated by considering your Heading,minus COG and adding BRG to the waypoint. In doing so, the soft-ware considers any Set to be included in the HDG value. If there is noSet, your HDG should be equal to COG. Set and Drift is calculated fromGPS and your Speed Log (NMEA 0183 VHW record or Pulse input)and Compass (NMEA 0183 HDM, HDT, orVHW) input or an operatormanual input.

Ori the right side ofthe lower left window you will find the Speed OverGround (SOG, calculated by MX42l smart GPS antenna), Speed Log(LOG, the NMEA 0183 or pulse speed input), and the Waypoint Clo-sure Velocity (WCV). WCV reflects the real time velocity from yourpresent position and course towards the next waypoint. The VMGand WCV are calculated from GPS data.

GPS7 - GPS StatusScreenThere are two windows in this display. The left window has twelve'graphic Power Bars representing the twelve GPS receiver channels ofthe MX42 I antenna. The PRN (PseudoRandom Number) under eachpower bar represents the satellite ID number assigned or being trackedon that channel. The power bars indicate the valid receiver powerrange from 30 to 50. Any portion of the power bar which is filled in,indicates that a satellite is being tracked on that channel. Ifa power baris empty, but a PRN number is labeled under the power bar, then theidentified satellite is not currently being tracked.

Status will tell you whether the correction data is being decoded iserror free or not. Normally, Status will indicate either DGPS mode OfT.DGPS OK, Tracking or Searching (Automatic search mode) or NoLock (Manual tuning mode). DGPS OK indicates that RTCM SC-104DGPS corrections are being received without errors within the AgeLimit set inCFGl DGPS. These information originates fromthe MX421 Bbeacon receiver. Searching indicates that the beacon receiver is search-ing for the appropriate frequency and/or" modulation of the beacontransmitter in automatic search mode. No lock indicates that the bea-con receiver is not receiving DGPS corrections from the selected sta-tion in manual tuning mode. You might see the label Tracking, whichindicates that a MSK beacon signal is present but DGPS correctionsare not being received. This is usually caused by high noise on thebeacon receiver or external device.If you press the E key, you can select between Automatic beaconsearch mode, Manual beacon tuning mode, or Qff. When the receiveris in the Manual tuning mode, you can use the cursor key to scrolldown into the large window below Station Selection and edit theReference Station name. The name you enter will always be associ-ated with the frequency to which you programmed the receiver. If youmove to another region that uses a frequency and name you previ-ously entered, the receiver will display the previously entered name.You can enter a new name for any manually tuned frequency at anytime.
