This study shows the test usage of Mobile Automated Astronomical System No. 1 (MAAS-1) in a local network with an area of approximately 50 km sq. The network has been built-up especially for experimental purposes to compare the local quasigeoid model determined by three different methods, namely GNSS-levelling, astronomical levelling and gravimetry...

The work is focused on astronomical positioning as a part of astronomical determination of vertical deflections. Several aspects of the topic are discused. The introduction discuse contemporary instumentation available, its capabilities and main deficiencies. The available instrumentation is regarded as not really satisfactory for modern tasks. As...

In this study a detailed gravity field is represented by the disturbing gravity potential and its first and higher order derivatives. These characteristics play an important role in geodesy providing a link between geometric and gravity space, but, under certain conditions, they can also contribute to structural interpretations of geodynamic phenom...

This article describes the process of creation and testing of a local quasigeoid model using the astrogeodetic method known as astronomical levelling. The process used here was based on astronomical levelling principles combined with the least square adjustment in a triangular network and a common method of surface generation. Using this method, th...

This paper is a summary of an experiment using Fresnel enantiomorphic diffraction in geodetic laser methods. In this study, results from the analysis of a large data set made possible the determination of the degree of accuracy of laser beam axes under various surveying conditions. An important part of the results is formed by the conclusions deriv...

Determination of heights with help of GPS in local geodetic networks is still more actual respecting the fact that the GPS technology becames more and more effective with hardware progress, with improvements in measuring and evaluating procedures, and with better modelling of the disturbing influences. In comparison with GPS the employment of class...

The Śnieżnik Massif has complicated geological and tectonic structure. The continuing crust movements, proved on the grounds of geological, geodetic (precise levelling) and satellite (GPS) investigations, confirm present-day mobility of this area. During the past decade (1993-2003) geodynamic research based on repeated satellite (GPS) measurements...
