Overview

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.

Engaging software

The GS18 T RTK rover combines seamlessly with the completely engaging Leica Captivate software for a powerfully immersive experience. Through the simplicity of touch, management of complex data is made extraordinarily enjoyable and actionable. Leica Captivate spans industries and applications with little more than a simple swipe, regardless of whether you work with GNSS, total stations or both.

Infinite possibilities

While Captivate captures and models data in the field, Leica Infinity software processes the information back in the office. A smooth data transfer ensures the project stays on track. Captivate and Infinity work in conjunctionto join previous survey data and edit projects faster and more efficiently.
With integrated quality assurance, this GNSS RTK rover records how the pole was levelled during the measurement and stores the values, ensuring measurement traceability and complete quality reporting.

Powerful handheld devices

In a controller or tablet, take your entire office on the go when you discover the power to overcome any environment from the palm of your hand. The Leica CS20 controller and Leica CS35 tablet provide the ultimate in control and convenience with complete mobility. Touchscreen technology allows for comfortable and quick data processing while a stunning 3D view transforms your GNSS experience.
