Therefore the transfer of geodetic networks consists of the separate transfer of both the position and the bearing. Whereas the transfer of the position can be managed by mechanical or optical plumbs, the orientation of the underground network often is determinded by high-precision surveying gyroscopes for north-seeking. This method however, is influenced by deflections from the vertical which are not exactly known. This paper describes a novel method to transfer the bearing by combination of autocollimation with a high-precision inertial navigation system (INS). The principles of autocollimation and INS are introduced. The motion-sequence consists of a reverse movement - comparable to a measurement in two faces - which provides a symmetric measurement and therefore minimizes the influence of systematic and time-proportional errors of INS.
