On the determination of Plumb-Line deflections using vertical gravity gradient anomalies in the geodetic test field near Grybów

The report presents studies concerned with the determination of vertical deflections in the vicinity of Grybow (Cracow district-the Carpathians) using anomalies of the vertical gravity gradient. The anomalies were integrated using derived kernel function round 14 stations. Because the second derivative of gravity disturbing potential under consideration is more sensitive to the influence of masses near station, the obtained components of vertical deflections in corrections to astro-geodetic levelling ought to be applied to investigate local "sub-centimetre" geoid undulations.
