It ensures reliable operation in all weather and climatic conditions, including the effects of precipitation in the form of rain, snow, fog, ice on the rails and at the low temperatures.
Rail track condition monitoring according to the main geometry parameters (cross level, gauge, alignment, longitudinal profile) in an extended speed range with high accuracy:

Longitudinal level relative to the 17 m chord with arms 2.7 m and 14.3 m (longitudinal profile)

Alignment relative to the 21.5 m chord with arms 4.1 m and 17.4 m, mm

Detecting of the track passport characteristics of the track

Statistical analysis of the rail track state (for runs for a period of up to 1 year, the frequency of deviations, the forecast of the development of deviations, etc.)
