Global Positioning System (GPS)

Definition

The Global Positioning System (GPS) is a satellite-based navigation system that provides accurate location and time information to a GPS receiver anywhere on Earth. It utilizes a network of satellites orbiting the planet, which transmit signals to receivers, allowing them to determine their precise location through triangulation. This technology is crucial for various applications, especially in areas like transportation management and automated toll systems.
