The global Worldwide Positioning System (GPS) network was designed by the US Department of Defense, as a way to track one’s exact location anyplace
in the world.
The GPS network consists of 24 navigation satellites, which orbit the planet at a height of close to 12,000 miles. These satellites each orbit the earth doubly every 24 hours, and they are set up in such a way that they can send signals to any location on the planet, whether it be land or sea, and no matter how remote.
The 24 GPS satellites are incessantly beaming positioning data, which can be picked up by GPS devices ( http://www.gpsdevices.info/ ) on the ground, and used to calculate exact latitude and line of longitude
coordinates. Depending on the device that is used, this data can be accurate to inside
a few meters.
Some GPS devices likewise provide advanced features such as dynamic mapping and elaborated
drive directions.
Despite the common idea that GPS-enabled devices are prohibitively expensive, and only useful in scientific and military operations, many an of these useful gadgets are primarily designed with the user
in mind. For example, GPS handhelds ( http://www.gpsdevices.info/gps-handhelds.php ) can be carried about on one’s pocket, and are really useful for a number of functions. Certain companies, including Nextel GPS ( http://www.gpsdevices.info/nextel-gps.php ), have even as begun group action
GPS technology with common user
products such as mobile phones.
