ABSTRACT

The paper describes the automation of astrogeodetic measurements in determining
astronomic station coordinates Φ, Λ and determining astronomic azimuth A. The
automation has been developed at the Faculty of Geodesy, University of Zagreb. The
results of precision testing are presented. There are also the applications of automated
astrogeodetic measurements in engineering geodetic practice illustrated, first of all those
needed for the determination of the surface of astrogeodetic geoid and for independent
check-up of geodetic networks above long tunnels, but also for the purpose of
increasing the accuracy in the tunnel cutting direction.

Keywords: automation, astrogeodetic measurements, astronomic coordinates, azimuth
