In Europe the densification and improvement of the high speed railway network has been made a priority, as it is generally accepted that railroads are most efficient for transporting people. In the near future high speed trains will connect all major towns with a speed of about 200 km/h. The Dept. of Engineering Geodesy, Technical University in Vienna, was involved in the development of fundamental concepts concerning geodetic networks and rail track alignment methodes.

The investigations have shown that the fundamental technical geodetic networks should be established in four steps. For a most economic organization of the measurement sessions simulation calculations have to be performed in advance. Approximate coordinates taken from a map and IGS orbit data were used.

For the railway track alignment a carriage was constructed carrying the rover of a DGPS system and other electronic sensors. The alignment calculations can be performed on-line, using algorithms based on Wiener filtering procedures.
