The Worldwide Global Positioning System (GPS) was originally designed for military purposes. It is currently used by thousands of civilians in a variety of applications. The system consists of 24 satellites that continuously orbit the earth. Between five and eight satellites are in range of an individual user from almost any location on earth. A GPS receiver can convert the coded satellite signals transmitted by the system and compute an exact location for the user.
The location is identified by its longitude, latitude, and altitude. A GPS receiver – like the GPS Ranger Series -- can help users find their way on a map, find out what restaurants or attractions are near them. And now with the Ranger Series, GPS can deliver compelling stories at any point of interest in the world! |
