GPS (Global Positioning System) is a satellite-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth. Its applications are widespread. Mobile phones utilize GPS for location-based services and navigation. Banking operations can leverage GPS for time synchronization across distributed systems, asset tracking, and secure transaction verification. Power grids use GPS for precise time synchronization, which is crucial for grid stability, fault detection, and load balancing across various substations and control centers.
