A GPS satellite is a type of satellite that helps determine the precise location of objects on Earth. These satellites are part of the Global Positioning System, which uses signals from multiple satellites to calculate a receiver's position. Each satellite orbits the Earth and continuously transmits information about its location and the time the signal was sent. There are currently 31 operational GPS satellites in orbit, ensuring that users can access location data anywhere on the planet. The system is widely used in various applications, including navigation for vehicles, smartphones, and even in agriculture and aviation for precise positioning.
