Glossar y INTRODUCTION 2 The GPS 126/128 is a powerful navigation tool that can guide you any- where in the world. T o better understand its operation and capabilities, it may be helpful to review the basic terms and concepts briefly explained below .
3 INTRODUCTION Glossar y Grid Coordinate system that pr ojects the earth on a flat surface, using square zones for position measurements. UTM/UPS and Maidenhead formats are grid systems. Ground Speed The velocity you are traveling relative to a gr ound position.
Navigation Basics INTRODUCTION 4 NORTH “ACTIVE FROM” WAYPOINT NORTH DTK CROSSTRACK ERROR BRG TRK GROUND SPEED DISTANCE “ACTIVE TO” WAYPOINT “ACTIVE LEG” The GPS 126/128 provides steering guidance and navi- gation information using degrees, a measurement measur ed in a clockwise direction fr om a north reference.
5 INTRODUCTION Keypad Usage and Data Entr y P T urns the unit on and off and activates screen backlighting. J Scrolls thr ough the main data pages in sequence and returns display from a submenu page to the main page. M Captures a position and dis- plays the mark position page.
Primary Pages Before we start the tour , let’ s briefly look at the five primary information pages used for the GPS 126/128. T o switch between pages press either the Q or J keys (see below). Satellite Page The Satellite Page shows satellite positions and signal strength.
Map Page The Map Page acts as a window . It allows you to view your position, the “path” you have traveled over , and nearby waypoints. A diamond icon in the center of the screen repr e- sents your current position. As you move, you will see a thin line called a track log appear along the path you have just covered.
Getting Started T our Now that you are familiar with the primary pages, it’ s time to take a tour . This is a live tour and is to be conducted with your unit installed and with the boat in the water .
3. Press F to clear the default waypoint name. 4. Press and hold the U key to scroll through the alphabet until the letter ‘D’ appears. 5. Press the R key once to move the character highlight to the next character space. 6. Repeat steps 3 and 4 until the word ‘DOCK’ is dis- played.
Using the Position and Map Pages (cont.) As you head out, the Position Page will help you monitor your movement. The direction you are moving (your track) and your speed are displayed on the upper part of the page, just below the graphic compass tape.
Going T o a W aypoint Once you’ve stored the “CHANNL” waypoint in memory , you can use the GPS 126/128 to guide you to it by performing a simple GOTO. A GOTO is nothing more than a straight-line course fr om your present posi- tion to the destination you’ve selected.
Going T o a W aypoint (continued) The GPS 126/128’ s Highway Page pr ovides graphic steering guidance to a destination, with an emphasis on a straight-line course to the desired waypoint and the distance and direction you are of f course.
2. Use the arrow keypad to move the field highlight to the ‘CANCEL GOTO?’ prompt at the bottom of the page and press F . Clearing a Cluttered Map Display After you’ve used the GPS 126/128 for a few trips, you may find that your map display has become a bit messy from keeping track of your every move.
Satellite Page The GPS 126/128’ s Satellite Page displays the status of various receiver functions. The status information will help you understand what the GPS 126/128 is doing at any given time, and will tell you whether or not the receiver has calculated a position fix.
Receiver Status and EPE Receiver status is indicated at the top left of the page, with the current horizontal accuracy (EPE, esti- mated position error , in feet or meters) at the top right. The status will be shown as one of the following condi- tions: Searching— the GPS 126/128 is looking for any available satellites in view .
EZinit Option Prompt The Satellite Page also provides access to the EZ init prompt whenever a position fix has not been calculated. (The unit must be in searching, AutoLocate, acquiring, simulator , or poor coverage mode.
Position Page (continued) Directly below the graphic compass tape are the track and speed fields. T rack is the compass direction representing your actual course over the gr ound, and Speed is how fast you’re moving. Below track and speed are two user -selectable fields.
Altitude Field When the GPS 126/128 is acquiring satellites or navigating in the 2D mode, the last known altitude is used to compute your position. In cases where the GPS 126/128 has 2D coverage, entering your approximate altitude will enable the receiver to determine a 3D fix.
T o add this waypoint to a route: 1. Highlight the ‘Add to route number’ field, and press F . 2. Enter a route number , press F to confirm and press F again to save the waypoint. Position A veraging Function The GPS 126/128 positioning averaging function will help reduce the ef fects of selective availability when marking a waypoint.

Press F to confirm the ‘DONE’ prompt, highlight the ‘YES?’ prompt, and press F . Note: This feature is handy for deleting temporary waypoints created by the T racBack function.
W aypoint Definition Page The waypoint definition page lets you create new waypoints manually or review and edit an existing way- point’ s coor dinates, symbols, and comments. It is also used to delete an individual waypoint from memory (see pg. 24).
Reference W aypoints (cont.) 2. Enter a waypoint name, and press F . 3. Highlight the ‘reference’ field, and press F . 4. Enter a reference waypoint name (or leave the field blank to use your present position), and press F . 5. Enter the bearing and distance of your new waypoint from the reference waypoint.
Renaming and Deleting W aypoints The rename and delete function fields are located along the bottom of the waypoint definition page. T o rename a stored waypoint: 1. Highlight ‘RENAME?’, and press F . 2. Enter the new waypoint name , and press F .
Selecting a GOTO Destination The GPS 126/128 provides four ways to navigate to a destination: GOTO, MOB, T racBack, and route navi- gation. The most basic method of selecting a destina- tion is the GOTO function, which lets you choose any stored waypoint as the destination and quickly sets a direct course fr om your present position.
T racBack Navigation GARMIN’ s patented T racBack feature allows you to quickly retrace your path using the track log automati- cally stored in the receiver . This feature eliminates the need to mark waypoints along the way and manually create and activate a r oute back to where you began your trip.
• If there ar e not enough available waypoints in memory to create a T racBack route, you will be alerted with a ‘waypoint memory full’ message, and the receiver will use any available waypoints to create a T racBack r oute with an emphasis on the track log closest to the destination (the oldest track log point in memory).
Route Navigation The last form of navigating to a destination with the GPS 126/128 is to create a user -defined route. The GPS126/128 lets you create and store up to 20 r outes of 30 waypoints each. The route navigation featur e lets you plan and navigate a course from one place to another using a set of pre-defined waypoints.
Route Definition Page The bottom of the route definition page featur es ‘function’ fields which let you copy , clear , invert, or activate the displayed route. Routes 1-19 ar e used as storage routes, with r oute 0 always ser ving as the active route you ar e navigating.
Creating and Navigating Routes T o create a route fr om the route definition page: 1. Highlight the ‘route number’ field, and press F . 2. Using the U or D key select an empty route number and press F . 3. Press F to begin entry of a route comment.
Active Route Page Once a route has been activated, the active r oute page will display the waypoint sequence of your route with the estimated time enroute (ETE) at your pr esent speed and the distance to each waypoint. As long as you are navigating an active r oute, the active route page will become part of the main page sequence of the unit.
Editing Routes A route can be edited anytime after its cr eation. T o edit a route fr om the active route page or the route definition page: 1. Select the waypoint you want to edit, and press F . An on-screen menu of editing choices will appear , with options for reviewing, inserting, deleting, or changing the waypoint field highlighted.
Using the Navigation Pages Once you’ve selected a GOTO destination or acti- vated a T racBack, MOB, or Route, the GPS 126/128 will provide graphic steering guidance to the destina- tion with one of .
Selecting a User -Defined Navigation Page (cont.) The fields located in the lower corners of both pages are user -selectable fields that allow you to display a vari- ety of navigation values for your trip. T o access the user -selectable fields: 1. Highlight either field, and press F .
35 REFERENCE Highway Page Using the Highway Page The GPS 126/128’ s Highway Page pr ovides graphic steering guidance to a destination waypoint, with a greater emphasis on the straight-line desired course and the distance and direction you are of f course.
