Trimble GEDO GX50

LASER SCANNING SYSTEM FOR KINEMATIC CLEARANCE ANALYSIS &

ASSET DATA COLLECTION APPLICATIONS

The Trimble GEDO GX50 is a modern and flexible laser scanning system that is designed to operate with Trimble GEDO track measurement systems.

The Trimble GEDO GX50 is available in a Single Head configuration with one scanner and in a dual head configuration with two scanners. The modular system design allows the second scanner to be added later. Depending on application specific requirements, the scanners can be mounted in different positions and tilt angles. The scanner positioned perpendicular to the track axis provides an optimum of accuracy for high precision clearance analysis. In the butterfly configuration, objects that are perpendicular to the track become clearly visible.

The high-resolution three-dimensional data obtained with the system quickly and precisely can be used for clearance verification and as-built data collection. In terms of accuracy and resolution, the data provides an excellent basis for modeling in a BIM-compliant design and construction workflow.

Trimble GEDO Scan Systems

The Trimble GEDO GX50 can be combined with the Trimble GEDO CE 2.0 track measurement trolley to form various Trimble GEDO systems. The track measurement trolley measures the track gauge and cant in conjunction with the distance traveled. The basic configuration, Trimble GEDO Scan, allows the acquisition of a purely relative or pseudo-absolute processed point cloud. In the geodetic Trimble GEDO Rec-Scan configuration, the absolute track position is determined using a total station or GNSS receiver. This position is also used for absolute
referencing of the point cloud. The Trimble GEDO IMS-Scan and Trimble GEDO IMS-GNSS-Scan systems combine state-of-the-art inertial measurement technology and laser scanner into a multisensor system. The flexible processing allows different types of georeferencing for an absolute referenced point cloud.

APPLICATIONS:

Planning, BIM and Construction

Documentation of track corridor state
Spatial data for 3D design modeling
Extensive clearance analysis for current track or new track to be designed
Overhead power line planning
As-built documentation after completion

Operation and Maintenance

Clearance analysis for extra-wide transports and cross-border rail traffic
Narrow-gauge documentation for the track infrastructure owners (e.g. WinLUE for LIRA and Clearroute)

Asset Management

Capturing rail asset objects for inventory documentation

Key Benefits:

Utilizing a universal track measurement trolley with modular expansion options
Full 360° measurement provides visibility of all objects at the track
Can be used with one or two scanners
Flexible alignment of scanners for optimal visibility of objects
High measuring frequency and rotation rate allows for fast trolley movement during recording
Uniform power supply and battery hot-swap functionality
Combination with geodetic instruments for absolute referencing of point cloud
High-resolution live display for immediate on-site clearance checks
High productivity and flexibility reduces personnel requirements and lowers costs
