A GPS system, or Global Positioning System, is a technology that allows users to determine their exact location anywhere on Earth. It works by using a network of satellites that send signals to GPS receivers, which then calculate the user's position based on the time it takes for the signals to arrive. This technology is widely used in navigation for vehicles, smartphones, and outdoor activities. In addition to navigation, GPS systems are also used in various applications such as mapping, surveying, and tracking. They provide accurate location data that can help in logistics, emergency response, and even agriculture. Overall, GPS technology has become an essential tool in modern life.
