Global Positioning System (GPS)

The Global Positioning System (GPS) is a satellite-based navigation system that allows users to determine their precise location anywhere on Earth, typically within a few meters. It consists of a network of satellites that orbit the planet and transmit signals to GPS receivers, such as those in smartphones or vehicles. By calculating the time it takes for these signals to reach the receiver from multiple satellites, the system can pinpoint the receiver's location in terms of latitude, longitude, and altitude. GPS is widely used for navigation, mapping, and various applications in transportation, outdoor activities, and emergency services.
