Navigation Satellite Timing and Ranging (NAVSTAR)

NAVSTAR, commonly known as GPS, is a global positioning system that uses a network of satellites orbiting Earth to provide precise location and timing information. These satellites transmit signals that are received by GPS devices, which calculate their exact position based on the time it takes for the signals to arrive. NAVSTAR enables various applications such as navigation, mapping, and time synchronization for systems like banking and power grids, making it a critical tool for accurate positioning and timing worldwide.
