Global positioning system (gps)

Definition

The global positioning system (GPS) is a satellite-based navigation system that allows users to determine their exact location anywhere on Earth. GPS operates by using a network of satellites that transmit signals to GPS receivers, enabling real-time positioning, navigation, and timing information. Its accuracy and reliability make it an essential tool for route planning and optimization in various applications, especially in logistics and transportation.
