The Leica GS18 T is the fastest and easiest-to-use GNSS smart antenna and RTK rover because you save time by no longer needing to hold the pole vertical to level the bubble. This latest innovation, with industry-leading technology, combines GNSS and inertial measurement units (IMUs) to be the first true tilt compensation solution immune to magnetic disturbances and it 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.
