Abstract

A method and apparatus for determining the position of a pressed-ahead hollow-section line, especially with any desired three dimensional curvature, and having measuring points permanently and securely arranged in the hollow-section line. The three dimensional position of the measuring points, e.g. signal emitters, is detected by automatic sensing devices e.g. cameras, having remote control or long-distance transmission, and being arranged in the hollow-section line.
