GPS Technology
GPS, or Global Positioning System, is a satellite-based navigation system that allows devices to determine their exact location anywhere on Earth. Developed by the U.S. Department of Defense, GPS works by sending signals from satellites orbiting the Earth to GPS receivers, such as those in smartphones and cars. The receiver calculates its position based on how long it takes to receive signals from multiple satellites, pinpointing its location in terms of latitude, longitude, and altitude. GPS is widely used for navigation, mapping, and tracking in various applications, including transportation, outdoor activities, and emergency services.

GPS, or Global Positioning System, is a satellite-based navigation system that allows a receiver, like your smartphone, to determine its exact location anywhere on Earth. It works by triangulating signals from a network of at least 24 satellites orbiting the planet. Each satellite transmits time-stamped signals indicating its location. The GPS receiver calculates how long it took for these signals to arrive, allowing it to pinpoint its own location with accuracy, typically within a few meters. GPS technology is widely used in navigation, mapping, and various applications from driving directions to tracking shipments.
