GRP1000 IMS Track Geometry Measurement System (with GNSS)

The system combines GRP1000 IMS with GNSS RTK real-time absolute positioning technology, and innovatively realizes that track measurement and control point network construction can be done at the same time, which can quickly establish absolute control for the existing lines.

Characteristics:

l  The measurement efficiency can be reach to 4km/h, and the track measurement and control point network construction can be done at the same time;

l  Save large amount of money and time;

l  Automatic calculation of track’s horizontal and vertical correction;

l  Automatic optimization of correction value;

l  Direct interface with the tamping machine;
