GPS

Definition

GPS, or Global Positioning System, is a satellite-based navigation system that provides location and time information anywhere on Earth. It works by using a network of satellites that transmit signals to GPS receivers, allowing users to pinpoint their exact location. In soil science, GPS technology plays a critical role in soil mapping and monitoring, enabling precise spatial analysis and data collection for various research applications.
