What is GPS? GETTING ST ARTED The Global Positioning System (GPS) is a system of 24 satellites which circle the earth twice a day in a very precise orbit and transmit information to earth. The GPS III must continuously “see” at least three of these satellites to calculate your position and track your movement. At times, additional satellites ma[...]

Once the GPS III has calculated a position fix, you’ll usually have anywhere from five to twelve satellites in view . The receiver will then continuously select the best satellites in view to update your position. If some of the satellites in view get blocked or “shaded,” the receiver can simply use an alternate satellite to maintain the posi[...]

This usually provides a position fix in 1 minute. Y ou’ll know you have a fix when the unit automatically transitions from the Satellite Page to the Map Page (shown left). Y our receiver is now ready to use! T o turn the unit off: 1. Press and hold the red power key for 1 second. T roubleshooting If you have trouble initializing or getting a posi[...]

T o 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. Y ou can quickly scroll thr ough the pages in either direction using the P AGE or QUIT keys. Let’ s briefly tour each of these pages in order to give you some insight into how they help you navigate. W e’ll [...]

Let’ s start with the Satellite Status Page, which is the page you’ll view while your unit is getting a position fix. If you’re not already on this page, pr ess P AGE or QUIT until it appears. The Satellite Status Page shows you status information that helps you understand what the receiver is doing at any given time, and it’ s a page that [...]

The Position Page shows you where you are, what dir ection 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[...]

The Map Page shows your movement using a real-time track log (an electr onic breadcrumb trail that appears directly on the map as you’r e traveling), and your present position as a pointer icon in the center of the map. The Map Page also shows any nearby lakes, rivers, highways and towns. Use the zoom keys (IN and OUT) to adjust the map to the de[...]

The GPS III features two differ ent 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 dist[...]

The GPS III’ s Highway Page also provides graphic steering guidance to a destina- tion waypoint. As you head toward your destination, the middle of the scr een pro- vides visual guidance to your waypoint on a moving graphic “highway .” Y our present position is at the bottom center of the highway display . The line down the middle of the high[...]

The GPS III’ s Main Menu pr ovides access to additional pages (submenus) that are used to create or edit waypoints, create r outes, list nearby waypoints, review trip infor- mation and timers or make changes to system settings. These six pages are divided into categories by function. The waypoint and route management features of the Main Menu are[...]

GPS is really about marking and going to places called ‘waypoints’. Before we can use the GPS III to guide us somewhere, we have to mark a position as a waypoint. Y our GPS III can hold up to 500 waypoints. T o mark your present position: 1. Press and hold the ENTER/MARK key . The Mark Waypoint Page will appear , with a default three-digit name[...]

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 pr esent 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 m[...]

T o cancel the current GOTO destination, simply select another destination. If no destination is currently desired, or you want to resume a pr eviously selected route, the GOTO operation may be cancelled fr om the GOTO Options Page. T o cancel the current GOTO destination: 1. Press GOTO. 2. Press MENU. 3. Highlight ‘Cancel GOTO’ and press ENTER[...]

The GPS III’ s Satellite Status Page pr ovides a visual reference of various r eceiver 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) u[...]

Y ou can use the sky view to help determine if any satellites are being blocked, and whether you have a current position fix (indicated by a ‘2D Navigation’ or ‘3D Navigation’ in the status field). Y ou can also set the sky view to a ‘T rack Up’ config- uration, causing the top of the sky view to align along your current track heading. [...]

Poor GPS Coverage — the r eceiver 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. T urn the unit off and back on to reset, and reinitial- ize the receiver if necessary . Simulating Nav — the [...]

EPE and DOP The Satellite Status Page also indicates the accuracy of the position fix, using Estimated Position Error (EPE) and Dilution of Precision (DOP) figur es.
