Leica GS18 T – World’s Fastest GNSS RTK Rover

Immune to magnetic disturbances and calibration-free – no need to level

You no longer need to hold the pole vertical to level the bubble with the new Leica GS18 T, the fastest and easiest-to-use GNSS smart antenna and RTK rover. This latest innovation combines GNSS and inertial micro units (IMUs) to be the first true tilt compensation solution immune to magnetic disturbances and is calibration-free.

As you no longer need to watch and level the bubble, you can focus on your task at hand and save time over conventional surveying practices. Uninterrupted, accurate positioning when surrounded by or in close proximity to metallic objects - measure where others simply couldn’t before. The GS18 T works directly out of the box without any calibration procedure.


The Leica Captivate field software is the perfect companion for the GS18 T. With easy-to-use apps, all measured and design data can be viewed and used, providing you with a clear understanding of your data in 2D and 3D view. Captivate spans industries and applications with little more than a simple tap, regardless of whether you work with GNSS, total stations or both.


Based on sensor fusion of IMU and GNSS, GS18 T’s tilt compensation is immune to magnetic disturbances and it works immediately without calibration. With the GS18 T, surveyors have the flexibility to measure points with a levelled pole and still save the tilt values of each measurement. That way you have the trust that what was measured, is correct.


Users with any GS18 model have the flexibility to log raw data into an SD card or the internal memory.


Tracking multi-frequency signals comes as standard with all Leica Geosystems GS sensors. Combined with an excellent GNSS antenna element and a position update rate of 20 Hz, GS18 T ensures reliable measurement quality.


Multipath reduction and interference mitigation options in Captivate boost GNSS signal tracking quality under harsh environments, which improves RTK availability and accuracy. Also, an interference toolkit will enable filtering to remove in- and out-of-band distortions for even more robust GNSS signal tracking.
