Frequently Asked Questions
What makes the Leica GS18 T unique?
The 60-degree tilt compensation range is the highest in the industry — triple the Trimble R10's 15-degree range. The 100 Hz position output enables smoother machine control guidance.
How does the Leica GS18 T tilt compensation work?
The GS18 T uses an integrated IMU that combines GNSS positioning with inertial measurements to compute accurate positions even when the pole is significantly tilted.
What is Leica MultiTrack?
MultiTrack is a Leica technology that maintains RTK tracking in challenging environments by using multiple satellite constellations and carrier frequencies simultaneously — reducing RTK dropouts near buildings and trees.
What controller works with the Leica GS18 T?
The Leica CS20 running Captivate software is the primary controller. Third-party controllers with Leica GNSS protocol support also work.
