A GPS device, or Global Positioning System device, is a technology that helps determine the precise location of an object on Earth. It uses signals from a network of satellites orbiting the planet to calculate coordinates, which can then be displayed on a map. GPS devices are commonly found in cars, smartphones, and handheld units for outdoor activities. These devices are useful for navigation, allowing users to find directions, track routes, and locate points of interest. They can also provide real-time updates on traffic conditions and estimated arrival times, making travel more efficient and convenient for users.
