Abstract (en)
[origin: WO2008028880A2] The application relates to a track measurement method as well as a high-precision measuring system for small railway construction sites. The aim of the invention is to develop a measuring unit for track construction purposes which determines and keeps a log of track geometry data, maintains the required accuracy, and has a very compact and lightweight design. The claimed measuring unit is composed of a tachymeter car, a target car, and a base station for determining positions with satellite assistance. In the disclosed track measurement method, the base station is set up by means of a known point of a reference network and starts sending the correction parameters. Two cars are placed in a railway section that is to be verified and lies in the vicinity of said known point. The stationary tachymeter car continuously measures its own position by means of satellite-assisted processes as well as the distance from and the angle relative to the reflector car with the help of a synchronized tachymeter. The movable reflector car detects the track geometry and combines said measured values with the positions determined from the satellite measurement and the measured values of the tachymeter.
