Global Positioning System (GPS) (U.S.)

The Global Positioning System (GPS) is a satellite-based navigation system operated by the U.S. government. It consists of a network of around 30 satellites orbiting Earth that send signals to GPS receivers on the ground. By analyzing how long it takes for these signals to arrive, the receiver can determine its exact location, speed, and time anywhere on Earth, 24/7. GPS is used in everyday applications like navigation for vehicles and smartphones, as well as in scientific, military, and commercial sectors. It provides precise positioning information by triangulating signals from multiple satellites.
