GPS (Global Positioning System) is a "constellation" of 24 well-spaced satellites that orbit the Earth and make it possible for people with ground receivers to pinpoint their geographic location. How GPS Works GPS system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the user's exact location.


The Cobra GSPM 3000 Nav One portable navigation system allows users to easily move from vehicle to vehicle with the GPS in hand–simply plug and go. The receiver offers automatic route navigation with turn-by-turn directions and clear voice guidance to either addresses or points of interest. It also includes more than two million points of interest, such as banks, hotels, restaurants, gas stations, and many more, as well as a point-of-interest search using business phone numbers. If the user strays off course or has to take a detour, the GPSM 3000 provides an automatic rerouting function. Users will appreciate the backlit, intuitive soft keys, which provide easy access to specific functions in any given mode without smudging your display. Additional features include an infrared port that instantly transfers addresses from your Palm OS- or Windows Pocket PC-based PDAs; an odometer, trip timer, and speedometer; a Trip Planner function that allows you to preprogram up to five destinations in each plan; and a Trail Mode that allows you to go off-roading and mark your favorite waypoints for the return. The unit uses Cobra’s exclusive Accelerated Satellite Acquisition Protocol II technology (ASAP II), which gets you running up to twice as fast as other recreational GPS receivers and provides superior reception in urban areas, canyons, and dense foliage. The device’s built-in altimeter and compass display altitude readings and eight cardinal compass points.
