Testování modelu kvazigeoidu na Karvinsku

Abstract

Target of this diploma study was to compare the different models of quasigeoids: CR2000, CR2005, EGM2008 and Eigen-6C3 on the selected area in the Karviná with my own measurement using technology GNSS-leveling. Differences were determined on the 20 points in Stonava, Albrechtice and city Havířov. Each point was measured 2 x for about 15 minutes (fast static method). Obtained results show possibility of using method GNSS- levelling for determination of vertical changes in mining areas.
