What is GPS?
The Global Positioning System, usually called GPS, is the only fully-functional satellite navigation system. A constellation of more than two dozen GPS satellites broadcasts precise timing signals by radio, allowing any GPS receiver (abbreviated to GPSr) to accurately determine its location (longitude, latitude, and altitude) in any weather, day or night, anywhere on Earth.

Russia operates an independent system called GLONASS (GLObal NAvigation Satellite System), although with only twelve active satellites as of 2004, the system is of limited usefulness.
