Abstract
A system and methods are disclosed for providing the location of a tunnel boring machine (TBM) by establishing of a plurality of known locations or 'monuments'; from these monuments located at least on, over or within the TBM's start point, known in the art as a 'pit'. The present invention provides among other things an integrated navigation system that provides real-time parametric guidance information to the TBM, relative to the tunnel origin, past course and current trajectory, while simultaneously employing a non-contact measuring system in concert with said origin and course information for the final provision of an as-built map of tunnel dimensions and centerline.
