Simple track geometry quality control surveys with as-built check
For easy control of rail quality, the Network Rail approved Trimble GEDO Doc system consists of the Trimble GEDO CE 2.0 track measurement trolley, the Trimble GEDO Profiler or Trimble total station and the Trimble TSC7 control unit running Trimble Access or Trimble GEDO Rec Module Doc. This is field software for recording the most important track quality parameters. The values are displayed during the measurement and can be output as a protocol in the field.

The system’s specifications make it suitable for as-built documentation of existing track, main track, side track, tram, metro and industrial lines. Optionally with Profiler for checking the track position at known points and distance measurement to objects close to the track.
• Entry level track survey for quality checks and collecting gauge, cant and twist
