Real Time Kinematics (RTK) technology by u-blox

High precision positioning can be achieved by combining Global Navigation Satellite Systems (GNSS), such as GPS, GLONASS, Galileo and BeiDou, with Real Time Kinematics (RTK) technology. RTK is a technique that uses the receiver’s measurements from the phase of the signal’s carrier wave. These measurements combined with corrections from a local “base” station or virtual base station, allow the receiver to solve carrier ambiguities and provide cm‑level accurate position information to the end‑user, a moving device, typically is referred to as the “rover”.
