What is GPS GNSS RTK and How Does It Achieve Centimeter Accuracy?

Standard GPS can tell you which street you're on, but for professionals in surveying, construction, and agriculture, this is nowhere near accurate enough. The solution is GPS GNSS RTK (Real-Time Kinematic), a transformative technology that elevates satellite positioning from meter-level approximation to centimeter-level precision. By using data from a fixed base station to correct errors in a moving receiver (the "rover"), RTK overcomes atmospheric distortions and other inaccuracies inherent in satellite signals. This technique provides the instant, survey-grade results required for the most demanding applications, from mapping a construction site to guiding an autonomous tractor. For any operation where absolute precision is the benchmark for success, GPS GNSS RTK is the indispensable technology that makes it possible.
