The Trimble GEDO Vorsys system consists of two Trimble GEDO CE 2.0 track measurement trolleys with a Trimble control unit and in combination with a Trimble total station.
The system is optimized for pre-measuring for track tamping. The measurement is based on the traditional rail alignment method, which guarantees high internal accuracy. The absolute track position is captured by measurements to control points. Deviations from the nominal track position are displayed live in the field, as well as the location of alignment transition points (main points).
The Trimble GEDO Vorsys system is used for easy-to-use and high productivity pre-measurement track tamping operations.
