The VF Rail survey trolley is an efficient method of track surveying with high accuracy. Measurements can be performed in 'stop and go' or kinematic mode.
The VF Rail survey trolley uses a robotic total station or GPS (GPS has lower accuracy than TS) for positioning, or, if suitable, a simultaneous combination of both a robotic station and a realtime updated free station (RUFR IS), or a continuous logging of data for post processing.
