Leica GS11 GNSS Receiver with X-PAD
Visual Surveying, Calibration-Free Tilt, and Everyday CAD Simplicity
The Leica GS11 paired with Leica X-PAD field software delivers a modern, visual-first surveying workflow designed to eliminate site bottlenecks. By integrating multi-frequency GNSS positioning, calibration-free tilt compensation, dual high-rate cameras, and an integrated laser EDM into a rugged pole-mount unit, the GS11 allows surveyors and site engineers to capture points they cannot reach and navigate stakeouts with live augmented reality (AR).
Controlled through the map-centric, Android-native Leica X-PAD interface, this system replaces complex menu navigation with intuitive touch and live video interactions—dramatically reducing field-to-office turnaround times.
Key Capabilities
-
Augmented Reality Stakeout: Dual integrated cameras project digital design points, offset alignments, and boundary lines straight onto a live video feed of the site within X-PAD. Operators walk directly to points using visual site context rather than repeatedly looking down at delta coordinates.
-
Measure Points Beyond Physical Reach: When obstacles, safety hazards, or property lines block the pole tip, the GS11 offers three distinct ways to measure: pole measurement with tilt, photogrammetric measurement from captured imagery, or targeting with the integrated Class 3R green laser distance meter.
-
Calibration-Free Tilt Compensation: Immune to magnetic interference, the onboard inertial system lets you measure immediately without levelling the physical vial, maintaining precision even around metallic structures, reinforced slabs, or moving vehicles.
-
Map-Centric CAD & BIM at the Pole: X-PAD runs natively on rugged Android controllers (such as the Leica CSX8) and third-party tablets. View and interact directly with native DWG, DXF, LandXML, and IFC files—snapping to line vertices and generating coordinate offsets on the fly.
-
Continuous Operation & Connectivity: Dual hot-swappable batteries deliver up to 12 hours of field operation without powering down. Dual communications via an integrated 4G LTE modem and multi-protocol UHF radio ensure flexible network RTK (Hexagon SmartNet) or local base-rover functionality.
