Determination of quasigeoid in local network using modern astrogeodetic technologies

Popis výsledku v původním jazyce

This study shows the very first usage of Mobile Automated Astronomical System No. 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 determined by three different methods, namely GNSS-levelling, gravimetry and using the newly presented MAAS-1 for the astronomical method. The network consists of 34 core points where the astronomic and geodetic coordinates have been measured. Subsequently the measured data has been processed to obtain vertical deflections and to determine the quasigeoid heights by astronomical levelling. Afterwards, the quasigeoid has been independently determined also using gravimetric measurements and by the method of GNSS-levelling. The resulting astronomical quasigeoid as well as the results of the comparison are being presented. The overall agreement of independently determined quasigeoids is on the level of 3 mm. After an overall accuracy evaluation of resul
