The Trimble GEDO IMS system consists of the Trimble GEDO CE 2.0 track measurement trolley with a Trimble GEDO IMU and a Trimble control unit in combination with a Trimble total station. 

The system is used for highly productive final inspection of  slab track, direct fixated and embedded track. The almost fully automatic geodetic resection in combination with the most modern inertial measurement technology optimizes the measurement process with highest accuracy.

Based on the measurement results, the acceptance reports and correction lists required for final inspection and quality control can be generated. 

The highly accurate and highly productive system is particularly suitable for high-speed lines and longer track sections.



  • Control of geodetic resection with total station 
  • Fully automated geodetic resection after completion of first setup
  • Capturing of absolute track position in combination with track gauge, cant (superelevation) and twist
