  • Page 12: What Is Gps

    GPS satellite and use this information to compute your position. Your GPS receiver can only see satellites above the horizon, so it needs to know what satellites to look for at any given time. To use this almanac data, your GPS needs to either be told its general location (“initialized”) or given the opportunity to...

  • Page 13: Initialization

    “shaded,” the receiver can simply use an alternate satellite to maintain the position fix. Although a GPS receiver needs four satellites to provide a three-dimensional (3D) fix, it can maintain a two-dimensional (2D) fix with only three satellites. A three-dimensional fix means the unit knows its latitude, longitude, and altitude, while a two-dimensional fix means the unit knows only its latitude and longitude.

    Satellite Status Page Active Route Page Highway Page To turn the GPS III back on, press and hold the red power key. The GPS III features six main pages which are linked together in a chain. You can quickly scroll through the pages in either direction using the PAGE or QUIT keys. Let’ s briefly tour each of these pages in order to give you some insight into how they help you navigate.

  • Page 16: Satellite Status Page

    GETTING STARTED Satellite Status Page The signal strength bars give you an indication of what satellites are visible to the receiver, whether or not they’re being used to calculate a posi- tion fix, and the signal quality. If satellite reception is lost, or an insufficient number of satellites are available, you will be alerted with a ‘Poor...

  • Page 17: Position Page

    The Position Page shows you where you are, what direction you’re heading, and how fast you’re going—and it’ s the page you’ll want to use when you don’t have a destination selected. A graphic compass display at the top of the page shows your direction of travel (track) while you’re moving, while six user-selectable data fields below display your current speed, average speed, trip odometer, trip timer, and sunrise/sunset times at your current position.

  • Page 18: Map Page

    GETTING STARTED Map Page With the map oriented to ‘track up’, the pointer always points up and the map rotates to your current direction of travel (track). Note the north indicator on the map. You can also select a full- screen map from the Map Page Options.

  • Page 19: Compass Page

    The GPS III features two different navigation pages: Compass and Highway. The Compass Page is first. This page provides graphic steering guidance to a destination waypoint, with an emphasis on the bearing to your destination and current direction of travel. (The Highway Page places greater emphasis on the straight-line desired course and the distance and direction you are off course.) The middle of the page fea- tures a rotating ‘compass ring’...

  • Page 20: Highway Page

    GETTING STARTED Highway Page If you move off course the highway display will move, indicating the direction you are off course. To stay on course, simply move toward the center of the highway. As you approach your desti- nation, the graphic highway will stop at the destination waypoint.

  • Page 21: Main Menu

    The GPS III’ s Main Menu provides access to additional pages (submenus) that are used to create or edit waypoints, create routes, list nearby waypoints, review trip infor- mation and timers or make changes to system settings. These six pages are divided into categories by function.

  • Page 22: Marking Waypoint Positions

    GETTING STARTED Marking Waypoint Positions Each waypoint stored in memory is identified by a unique name, up to six char- acters long (letters and/or numbers). Each waypoint may also be assigned a custom waypoint symbol, making it easy to identify the waypoint on the Map Page.

  • Page 23: Going To A Waypoint

    Once you’ve stored a waypoint in memory, you can use the GPS III to guide you to it by using the GOTO feature. A GOTO is really nothing more than a straight-line course from your present position to the destination you’ve selected. A GOTO can be performed several ways: by specifying the destination from the GOTO Page, graphi- cally from the map display or by highlighting the waypoint name on any page (such as the Nearest Waypoints List).

  • Page 24: Active Route Page

    GETTING STARTED Cancel GOTO/Active Route To cancel the current GOTO destination, select ‘Cancel GOTO’ from the GOTO Options Page. Use the LEFT/RIGHT keys on the rocker keypad to select the desired data item. Available items include course, distance, fuel, and sunrise/sunset times. To cancel the current GOTO destination, simply select another destination.

  • Page 25: Simulator Tour

    The GPS III is a powerful navigation system providing detailed mapping informa- tion in a convenient, compact package. This simulator tour is designed to show you the basic features of your new GPS III during a simulated trip. The simulator tour assumes that the receiver has been properly initialized as outlined in the Getting Started section of this manual, and that you have not changed any of the factory default settings.
  • Page 26 SIMULATOR TOUR Selecting Simulator Mode Select ‘Start Simulator’ from the Satellite Status Page Options to enable the built-in simulator.

  • Page 32 SIMULATOR TOUR Highway Page Use the LEFT/RIGHT keys on the rocker keypad to move off course / on course. To return to your course, steer toward the highway centerline. When you reach your destina- tion, the highway will end at the waypoint marker.

  • Page 33: Reference

    The GPS III’ s Satellite Status Page provides a visual reference of various receiver functions, including current satellite coverage, receiver operating mode, battery level and position accuracy. As the receiver locks onto satellites, a signal strength bar will appear for each satellite in view, with the appropriate satellite number (01-32) under- neath each bar.
  • Page 34 REFERENCE Satellite Status Page ‘2D Navigation’ means the GPS III has determined a hor- izontal position (latitude/ longitude), but is unable to determine altitude. Additional satellites may be needed. ‘3D Navigation’ means the GPS III has determined a hor- izontal and vertical position (latitude, longitude and alti- tude).

  • Page 35: 'Need To Select Initialization' Prompt

    Poor GPS Coverage— the receiver isn’t tracking enough satellites for a 2D or 3D fix due to bad satellite geometry. Not Usable— the receiver is unusable, possibly due to incorrect initialization or abnormal satellite conditions. Turn the unit off and back on to reset, and reinitial- ize the receiver if necessary.
