Details
The Leica GS18 is a self-learning GNSS smart antenna designed for surveyors working with network RTK systems like HxGN SmartNet. It delivers the core functionality of the GS18 T without tilt compensation, but can be upgraded to include tilt capability at any time—enabling you to add efficiency and safety improvements as your business grows.
Operating as both rover and base, the GS18 tracks multi-frequency signals at 20 Hz with multipath reduction and interference mitigation through Leica Captivate field software. This combination ensures robust signal tracking even in harsh environments, improving RTK availability and accuracy. Built-in 4G LTE connectivity and an interference toolkit provide filtering to remove in- and out-of-band distortions.
Captivate's intuitive interface lets you view measured and design data in 2D and 3D across surveying applications—whether you're using GNSS, total stations, or both. Flexible and scalable, the GS18 grows with your operation while maintaining the measurement quality and reliability Leica Geosystems is known for in the field.
