The Trimble GEDO GX50 is a versatile and modern laser scanning system designed to seamlessly integrate with Trimble GEDO track measurement systems.
It is available in both a single-head configuration, featuring one scanner, and a dual-head configuration, equipped with two scanners to support enhanced data capture and efficiency.
Trimble GEDO Vorsys is an ideal tool for avoiding ballast tamping machines and work crews costly idle time in both conventional and high-speed rail tamping applications.
The Trimble GEDO GX50 can be paired with the Trimble GEDO CE 2.0 track measurement trolley to create a range of Trimble GEDO system configurations.
The track measurement trolley records track gauge in combination with the distance travelled. In its basic setup, Trimble GEDO Scan, the system enables the capture of a purely relative or pseudo-absolute processed point cloud.
With the Trimble GEDO Rec-Scan (geodetic) configuration, the absolute track position is calculated using a total station or GNSS receiver. This information is then used to provide absolute referencing of the point cloud.
The Trimble GEDO IMS-Scan and Trimble GEDO IMS-GNSS-Scan systems integrate advanced inertial measurement technology with laser scanning to create a powerful multi-sensor solution. Flexible processing workflows support multiple georeferencing methods, delivering a fully absolutely referenced point cloud.
