RTK stands for Real-Time Kinematic. It’s a technique that corrects GPS signals to deliver centimeter-level positioning. Unlike standard GPS, which can drift by several meters, RTK provides instant, reliable coordinates. This page breaks down how RTK works, and why it’s so much more precise.
A reference point sends real-time corrections to your receiver, enabling highly accurate and stable positioning.
Standard GPS uses satellite signals, but these signals can be distorted by atmospheric conditions or nearby structures. RTK adds an extra layer: a reference station (or network) with a known location compares raw GPS data and sends correction signals to your receiver. This real-time communication drastically reduces positional errors.
An RTK setup includes a receiver, a reference source, and a live connection between the two.
Every RTK system requires three essential components:
When these elements are connected, your GPS position is corrected in real time.
Knowing how RTK works helps you get more out of it. Start here with clear and simple insights.
