GPS

Definition

GPS, or Global Positioning System, is a satellite-based navigation system that provides accurate location and time information anywhere on Earth. It connects various devices through a network of satellites orbiting the planet, allowing users to determine their exact position, speed, and direction. In the context of connected logistics and the Internet of Things (IoT), GPS plays a critical role in real-time tracking, route optimization, and enhancing supply chain efficiency.
