Robot Techniques and their Impact on Surveying SystemsElectronic sensors for direction and distance measurements and more powerful and cheaper computers opened the way to new applications for electronic theodolites and tacheometers. 3D-measurement systems were developed for surveying of industrial objects using triangulation, trilateration, or polar measurement methods.

Engineering networks in a threedimensional reference frame movement of such a local reference frame with respect to a fixed one attached to the datum point. The influence of the change of the local vertical and horizontal reference directions is outlined and numerically documented. Finally the transformation of one local level reference frame into the glob

Tidal Corrections in Geodetic Height Determinations, and third order ocean loading effects. Since these phenomena affect precise geodetic observations and make them time-dependent it is necessary to reduce time-variable geodetic observables and derived quantities in order to correspond to a quasi-stationary, time-invariant state. Here we evaluate t

Transferring the Bearing Using a Strapdown Inertial Measurement Unitd its transfer is focussed upon in this paper. Strapdown-systems differ from the conventional gimballed platform-configuration by the use of the sensors which are sensitive to a rotation of the IMU. The gyroscopes, usually three Ringlasergyros or two Dynamical Tuned Gyros are, in addition to the acc

GPS as a Tool for Engineering Applications of Geodesyg surveying and geodesy. GPS is a second generation system of navigation satellites, which is to become fully operational sometime during 1992–93. At present (1991) the GPS constellation is made up of 10 block II (operational) and some (currently 5 working) block I (engineering test) satellites. The

Formfinding of Lightweight Surface Structures by Geodetic Methodsfrom geodesy to the elastomechanics of structures and vice versa. This not only has opened a completely new field of applications but has allowed also to gain revealing insights into both theories: Adjustment by least squares and elastomechanics of prestressed cable nets. Naturally, I have to confin

A Unified Alignment Model for Rotating Machineryontext of the Industrial Alignment Project at the University of Calgary which is a cooperative venture between a number of researchers at the university and thirteen companies. The main idea behind this modelling effort was the creation of a common framework in which the observables coming from diff
