RTK--- (Real-time kinematic positioning)
Real Time Kinematic is a technique used to increase the accuracy of GNSS (GPS, Glonass, Galileo, BeiDou, etc.)
signals by using a fixed base station which wirelessly sends out corrections to a moving receiver (rover).
By using these corrections, the RTK GNSS receiver can fix the position of the accuracy up to 2.5cm.
