INTRODUCTION Glossary The GPS 126/128 is a powerful navigation tool that can guide you any- where in the world. To better understand its operation and capabilities, it may be helpful to review the basic terms and concepts briefly explained below. - Page 7 Grid Coordinate system that projects 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 ground position. Latitude The north/south measurement of position perpendicular to the earth’ s polar axis.

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. To switch between pages press either the keys (see below). Satellite Page The Satellite Page shows satellite positions and signal strength. -
Page 11: Primary Pages
Navigation Page A navigation page gives you steering guidance when going to a waypoint. The GPS 126/128 has two naviga- tion page choices: the Highway Page and the Compass Page. The Highway Page is the default and will be briefly explained here. -
Page 12: Power On & Marking A Position
The tour will take you through the receiver’ s basic features and functions as you move about on the water and assumes that the GPS 126/128 is turned on and initialized, (see page 52 for initialization proce- dure) and that you have not changed any of the factory settings (units of measure, selectable fields, etc.). -

Position Page (or whatever page was displayed M key). The ‘DOCK’ waypoint prior to pressing the is now stored in the GPS 126/128’ s memory, and will remain there until you manually remove it or clear the receiver’ s memory. For more on waypoint management, see pages 19-24. -
Page 14: Map Pages
GETTING STARTED Position and Map Pages The Map Page displays your present position as a diamond icon and provides a real-time graphic “bread- crumb” display of your track right on the screen. The moving map’s default screen orientation is track- up. -
Page 15: Going To A Waypoint
Going To a Waypoint 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 from your present posi- tion to the destination you’ve selected. -

Page 18: Satellite Page
Satellite Page Status Field 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. -
Page 19: Backlighting
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. AutoLocate— the GPS 126/128 is initializing and collecting new almanac data. -
Page 20: Position Page & User Selectable Fields
Memory Erase Function You may erase the GPS 126/128’ s memory in four quick steps. This will cause all stored data to be deleted, including routes, waypoints, and the track log. - Page 21 Position Page (continued) Directly below the graphic compass tape are the track and speed fields. Track is the compass direction representing your actual course over the ground, and Speed is how fast you’re moving. Below track and speed are two user-selectable fields. Both user selec- table fields can display a variety of information that will aid in navigation The left field offers options for TRIP (default), AVSPD, MXSPD, TTIME, and ELPSD.

Page 29: Selecting A Goto Destination
Selecting a GOTO Destination The GPS 126/128 provides four ways to navigate to a destination: GOTO, MOB, TracBack, 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 from your present position. -
Page 30: Tracback Navigation
, highlight ‘TRACBACK?’, and press Once the TracBack function has been activated, the GPS 126/128 will take the track log currently stored in memory and divide it into segments called legs. Up to 30 temporary waypoints will be created to mark the most significant features of the track log in order to duplicate your exact path as closely as possible. - Page 31 • If there are not enough available waypoints in memory to create a TracBack route, you will be alerted with a ‘waypoint memory full’ message, and the receiver will use any available waypoints to create a TracBack route with an emphasis on the track log closest to the destination (the oldest track log point in memory).
-
Page 32: 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 routes of 30 waypoints each. The route navigation feature lets you plan and navigate a course from one place to another using a set of pre-defined waypoints. -
Page 33: Route Definition
Route Definition Page Comment Field Desired Track of Leg Copy Field Function Prompts The bottom of the route definition page features ‘function’ fields which let you copy, clear, invert, or activate the displayed route. Routes 1-19 are used as storage routes, with route 0 always serving as the active route you are navigating. -

Page 35: Active Route
Active Route Page Once a route has been activated, the active route page will display the waypoint sequence of your route with the estimated time enroute (ETE) at your present speed and the distance to each waypoint. As long as you are navigating an active route, the active route page will become part of the main page sequence of the unit. - Page 36 On-Route GOTO At the beginning of this section, we mentioned that the GPS 126/128 will automatically select the route leg closest to your position as the active leg. This may mean that you are not navigating to the first waypoint in the active route.
