The Trimble GEDO IMS-GNSS 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 GEDO Profiler and a Trimble GNSS receiver.

The system enables track as-built measurements and subsequent optimized alignment calculation utilizing Trimble GEDO NovaTrack software. The calculation is based on absolute coordinates with rail specific alignment elements. 

During the as-built track survey, control points can be established and measured for use in the subsequent track reconstruction or maintenance measurement process. The resulting track correction values are used for planning purposes or can be directly handed over to track construction machines. 

The system can also be used with a laser scanner instead of the Trimble GEDO Profiler. This allows for extensive clearance analysis required for new track position planning purposes, and, at the same time, to capture objects along the track for as-built and asset documentation purposes.
