RTK Base Stations

Real-time kinematic positioning (RTK) is the technology for the real time correction the common errors that occur in working with GNSS. A base station has a central role in this technology, as it receives the signals from the GNSS and uses measurements of the phase of the signal's carrier wave in addition to the information content to calculate the errors in the GNSS signals. A base station usually comes with an internal or external radio or modem to transmit the correction signals.
