RTK + VSLAM: Lymow’s Precision Formula

RTK Overview

Real-Time Kinematic (RTK) is a satellite-based navigation technique that enhances the precision of positioning data. By using the signals from satellites, RTK can achieve centimeter-level accuracy, making it ideal for applications that require precise location tracking, such as autonomous driving, drones, and robotics. In the application of smart lawn mowers, RTK allows for efficient navigation without the need for boundary wires, enabling them to operate seamlessly in a designated area.

What’s the Difference Between RTK, GPS, and GNSS?

GNSS (Global Navigation Satellite System) is a global system that provides positioning, speed, and time data anywhere on Earth. It includes systems like GPS, Galileo, GLONASS, and Beidou.


RTK is a specialized technology built on GNSS. It uses satellite signals from GNSS to deliver real-time, centimeter-level accuracy, making it ideal for precision-based applications like robotic lawn mowers.


How RTK Works

RTK achieves real-time, centimeter-level accuracy using GNSS. It relies on a reference station that continuously observes satellite data and sends it to a mobile station. The mobile station receives both the satellite signals and reference station data, then calculates its exact 3D coordinates in real time based on the relative positioning principle.
