GPS is based on triangle technology which
able to recognize your location.
This technology Is done by satellites
which needed to be maintained daily.

The GPS project was launched in the United States in 1973 to overcome the limitations of the previous navigation systems, incorporating ideas from the previous systems, including several classified engineering studies from the 1960s. The United States Department of Defense developed the system, which originally used 24 satellites.

First, the system was developed for the United States Army and in 1995 began to operate fully. The system was allowed for civilian use as early as the 1980s. GPS development and invention are attributed to Roger L. Easton of the US Naval Research Laboratory (AN), Ivan A. Getting of the corporation (The Aerospace Corporation), and Bradford Parkinson of the John Hopkins Physics Lab.
