What is GPS/RTK?

GPS/RTK (Real-Time Kinematic) is a satellite navigation technique used to enhance the precision of position data derived from satellite-based positioning systems (global navigation satellite systems, GNSS) such as GPS, GLONASS, Galileo, and BeiDou. It relies on a fixed base station receiving the same satellite signals as the rover, and uses this data to provide real-time corrections to the rover. This greatly improves positional accuracy, often down to centimeter level. It's commonly used in surveying, precision agriculture, construction, and autonomous navigation.
