GPS navigation is a technology that uses signals from satellites to determine the precise location of a device, such as a smartphone or a car's navigation system. By receiving these signals, the device can calculate its position on Earth and provide directions to a desired destination. This system is widely used for driving, walking, and even boating, making it easier for people to find their way. The Global Positioning System (GPS) consists of a network of satellites orbiting the Earth, ground stations, and receivers. When a GPS receiver picks up signals from multiple satellites, it can triangulate its position. This information is then used to create maps and offer real-time navigation assistance.
