Trimble GEDO measurement systems provide millimeter accuracy for all slab track surveying applications.

When constructing slab track, direct fixated and embedded track, fast and precise measurements and display of live results are required. Trimble GEDO systems provide all relevant information in real time. This means that deviations from the designed track position can be corrected immediately. 

After the concrete pour, any necessary correction values for fine adjustments are determined, and the final check measurement is carried out.  

Trimble GEDO systems are used worldwide during and after the construction of high-speed railway lines and in LRT and metro environments. The flexible design allows the use with a wide range of construction and alignment methods (i.e. Rheda system, Porr, and others). 

The Trimble GEDO Track System is used for the installation process and final inspection. The Trimble GEDO IMS system enables highly productive final inspection. 

The Trimble GEDO SPS system is used to install track support plates when rails have not yet been installed.

The PSCD system allows the control of track support plates during the production process.
