POS TG provides mm accuracy track geometry measurements,
using non-contact technology at revenue-traffic speeds.
The integrated Inertial/GPS system allows for a variety of geometry measurements to be accurately computed including, longitudinal profile, horizontal alignment, gauge, superelevation and twist.
The system can also be used for railroad surveying to provide
submetre-accuracy geographic positioning.
