Extension of a revolutionary measuring principle

Long-chord method with only one measurement trolley for as-built survey

Combined survey of relative and absolute track geometry

Unrivalled survey performance up to 5000 m/h

Repeat accuracy ± 1 mm

Up to 90% cost savings compared to traditional methods

Unlimited use during day and night, rain and bright sunshine - no line of sight requirements

Measurement of objects close to track

Modular system design

Measuring trolley consisting of precision sensors for gauge, superelevation and distance and ruggedized notebook

AMU 1030 (Amberg Measuring Unit) for unrivalled kinematic measurement precision

Two different control point measuring devices:

Total station (IMS 1000, fully automatic measurement)

Profiler 110 FX (IMS 3000)

Modular system upgrading possibilities

Global 3D topographic track survey

Measuring performance up to 4000 m/h, typically 2500 m/h

Absolute 3D control points given in global coordinate grid and used as transformation references

Distance between CP measurements up to 500 m

Fully compatible with other geodetic 3D survey data

Local 3D topographic track survey

Measuring performance up to 4000 m/h, typically 2500 m/h

Setup and survey of control points during initial track survey

Track data available in local 3D coordinate grid

Determination of local 3D coordinates for established control points

Results can be used for local track design and track works as well as monitoring purposes

Relative track geometry survey

Measuring performance up to 5000 m/h, typically 3500 m/h

Stationing plates as references

Measurement and calculation of track parameters horizontal versines (variable chord length), vertical versines (variable chord length), gauge, superelevation and twist

Presentation and analysis of track data with sophisticated

Track Geometry Record (TGR)
