Global Positioning Systems (GPS) are satellite-based navigation systems that help people determine their exact location anywhere on Earth. By using signals from a network of satellites orbiting the planet, GPS devices can pinpoint your position in terms of latitude and longitude. This technology is widely used in cars, smartphones, and even in outdoor activities like hiking and boating. GPS works by triangulating signals from at least four satellites to calculate your precise location. It can also provide information about speed, direction, and distance traveled. This makes it an essential tool for navigation, mapping, and various applications in fields like transportation, emergency services, and geography.
