GRP 1000 Rail

Surveying System
The Amberg GRP 1000 rail surveying system is configured for high accuracy and high productivity track measurement and construction. Amberg GRP 1000 is perfect for slab track construction, ballasted track construction and maintenance, and quality control of track geometry.

It has precise 3D track coordinates when used with the Leica total station; gives results and corrective data in real time; records the outer and inner track geometry; and offers optional expansion to the GRP 3000 or GRP 5000 series and more detailed data.

GRP 3000 Rail

Surveying System
The Amberg GRP 3000 is the comprehensive system solution for point survey of clearance as well as track geometry survey. It is perfect for clearance profile surveying, catenary works, design surveys, and track geometry surveys.

It offers a unique combination of the precise track geometry recording unit TGS FX and the Profiler 100 for automatic clearance profile surveying. The visible red laser dot allows accurate and rapid manual surveying of specific points, with real time comparison between as built and theoretical clearance envelopes, through a highly flexible and configurable data interface, to enable precise coordinate surveying in combination with the Leica total station. The system can be expanded into the GRP 5000.

GRP 5000 Rail

Surveying System
The Amberg GRP 5000 is the mobile system rail surveying solution for complete route documentation and comprehensive infrastructure analysis. It gives complete clearance profile analysis, inventory and design surveying.

It will enable automatic acquisition of the track environment, a very high measuring density with up to 500,000 measured points per second, high resolution of geometric data, complete clearance checks based on the measured data, and modularity and functionality due to the GRP FX concept.

GRP System FX

The platform of the GRP System FX is the TGS FX track gauging trolley.

Manufactured to the highest engineering standards, it combines precision sensors with practical design, making the GRP System FX a reliable partner in the challenging railway survey environment.
