Real-Time Kinematic (RTK) is a high-precision satellite positioning technology that dramatically improves the accuracy of standard GNSS systems such as GPS, Galileo, BeiDou, and GLONASS. While conventional GPS typically provides position accuracy in the range of 3 to 10 meters, RTK enables centimeter-level precision (approximately 1–3 cm) by using real-time correction data generated by reference stations at known locations. These stations continuously measure errors in satellite signals—caused by atmospheric effects, satellite clock drift, and orbital inaccuracies—and transmit correction data to mobile receivers (rovers). By applying these corrections in real time, RTK achieves an accuracy improvement of nearly 100×, making it an essential technology for autonomous vehicles, drones, robotics, and any system that must operate safely and reliably in constrained or complex environments.
At Village Island, we believe that centimeter-level positioning will soon become a fundamental requirement, and that strong convergence with broadcast infrastructures will naturally follow to ensure scalable, reliable, and resilient delivery of correction data.

The GEODNET Network comprises thousands of triple-frequency, full-constellation GNSS reference stations installed globally. Achieving centimeter-accurate RTK-fix is made easy by GEODNET, with its continuously expanding coverage map.
Each GEODNET station features a geodetic-grade antenna calibrated by the United States National Geodetic Survey. All stations undergo 24×7 monitoring and are positioned with Precise Point Positioning (PPP). The GEODNET network provides data through the NTRIP protocol and adheres to the internationally accepted RTCM3.2 protocol. GEODNET’s service is highly compatible with a wide range of user equipment.
