Gps global positioning system

GPS is a satellite-based navigation system that allows users to determine their exact location on Earth. It consists of three parts: satellites in orbit that transmit radio signals, receivers that detect these signals, and software that calculates the user's position. Originally developed by the US Department of Defense in 1973, GPS has both military and civilian applications. It works by using at least four satellites to triangulate the user's position based on the time it takes signals to reach their receiver. Ground stations monitor the satellites and send updates to keep them on their precise orbits. GPS is now widely used in mobile phones, automotive navigation, disaster relief, wildlife tracking, and more.
