Trimble GEDO GX50 Dual Head Rail Scanning System

The Trimble® GEDO GX50 Dual Head Scanner from is a high-performance kinematic laser scanning solution purpose-built for rapid, precise capture of railway corridor geometry and asset data. Designed to integrate seamlessly with Trimble GEDO track measurement systems, the GX50 enables simultaneous collection of dense 3D point clouds and track parameters, delivering the accuracy and efficiency required for modern rail surveying, clearance analysis, and BIM-driven infrastructure workflows.

Featuring a modular dual-head configuration, the system uses two scanners that can be mounted at configurable angles—including perpendicular or “butterfly” orientations—to maximize object visibility and optimize accuracy for clearance and asset capture. High measurement frequency and rotation rates allow fast trolley movement during acquisition, while full 360° coverage ensures complete visibility of surrounding infrastructure without additional passes.

Key Features

• Dual-head laser scanning configuration delivering dense, high-resolution 3D data with full 360° field of view.

• Modular design allows operation with one or two scanners and flexible alignment for optimal visibility and application-specific accuracy.

• High-speed data capture with measurement rates up to 1 MHz (dual head) and scanning speeds up to 240 Hz, enabling rapid corridor acquisition.

• Measurement accuracy of approximately 2 mm at 30 m with a maximum range of up to 80 m, supporting precise clearance and asset analysis.

• Seamless integration with the Trimble GEDO CE 2.0 trolley for synchronized measurement of gauge, cant, and traveled distance.

• Supports relative, total-station, GNSS, or IMU-based georeferencing workflows for absolute point cloud positioning.

• High-resolution live display enables immediate on-site clearance verification and quality control.

• Rugged IP65-rated system designed for rail environments, operating from –20°C to +50°C.

• Internal battery operation with Trimble S-Series Li-Ion batteries for mobile, field-ready deployment.

Ideal For

The GEDO GX50 is ideal for railway professionals performing clearance analysis, gauge verification, and detailed corridor documentation where accurate, high-density spatial data is required. It supports BIM-driven rail design, digital twin development, and infrastructure modernization projects, including overhead line planning and expansion.
