RTK Correction Network

RTK (Real Time Kinematic) is a technology used to correct common errors in satellite-based GNSS (Global Navigation Satellite System) positioning systems, including GPS, GLONASS, Galileo and BeiDou. Error corrections are generated using permanently installed reference stations connected to a central server.

Reference stations measure and record signals received from satellites and transmit this data to the central server. The server calculates correction data for the measured signal errors and delivers these corrections to mobile surveying devices via mobile internet. By applying these corrections, centimeter-level accuracy is achieved in the field.

In Estonia, we use the latest technology from CHCNAV, the world’s second-largest GNSS technology manufacturer. Our network is built on base stations that support and compute corrections for GPS, GLONASS, Galileo and BeiDou satellite constellations. This ensures the maximum possible number of satellites is utilized.

We offer flexible pricing and access to the network service regardless of your workload or project duration.
