The Global Positioning System (GPS) is a satellite based global navigation system which provides time and location services to users across the globe. The constellation is formed of 31 active satellites that broadcast a precision code and navigation message down to Earth. In order to obtain the most accurate time and location data, a receiver must be within line of sight to at least four satellites.


Bands L1 and L2 are available for civilian use, while band L5 is designated for aeronautical services.
