6ReferenceAbout GPS The Global Positioning System (GPS) is a system of24 satellites which circle the earth twice a day in a veryprecise orbit and transmit information to earth. TheeMap must continuously “see” at least three of thesesatellites to calculate your position and track yourmovement. At times, additional satellites may be neededto determine a position.By using an almanac (a timetable of satellitenumbers and their orbits) stored in the receiver’smemory, the eMap can determine the distance andposition of any GPS satellite and use this information tocompute your position.The Map Page is the main operating page of theeMap. All system programming and options are designedto support navigation activity using the Map Page.The Map Page shows your movement using a real-time track log (an electronic bread crumb trail thatappears directly on the map as you’re traveling), andyour present position as a triangle icon in the center ofthe map. The Map Page also shows any nearby lakes,rivers, highways and towns. Use the zoom keys (IN andOUT) to adjust the map to the desired scale.The map can be oriented with the top of the pagealways pointing north or it can automatically rotate tokeep your current direction of travel (track) at the top ofthe screen. The default setting is ‘North Up’, whichkeeps the top of the page always pointing north.
