Modeliranje plimovanja trdne Zemlje pri določanju položaja 3D točk kombinirane geodetske mreže : diplomska naloga

Brglez, Robert (author), Kuhar, Miran (mentor)

V diplomski nalogi smo predstavili vpliv plimovanja trdne Zemlje na spremembo 3D položaja točk nove kombinirane geodetske mreže 0. reda. Opisali smo namen vzpostavitve, stabilizacijo točk in predvideno opremo, ki bo nameščena na petih točkah kombinirane geodetske mreže 0. reda. Prav tako smo predstavili osnovna teoretična ozadja plimovanja trdne Zemlje, opisali različne modele plimovanja in poudarili upoštevanje plimovanja trdne Zemlje pri povezavi terestričnega koordinatnega sistema z višinskim sistemom. Na primeru dveh točk mreže 0. reda, Areh in Priložje, smo modelirali plimovanje trdne Zemlje. Pokazali smo spremembe 3D položaja in spremembe težnega pospeška, ki se pojavijo zaradi vplivov privlačnih sil nebesnih teles. Spremembe smo prikazali za dva različna letna časa. Ugotovili smo, da ima plimovanje trdne Zemlje večji vpliv na spremembe položaja v poletnem času, kadar pride tudi do amplitud, ki znašajo do okoli 35 cm v višinski komponenti. Pomembna je tudi ugotovitev, da položaj točk znotraj Slovenije nima vpliva na spremembe zaradi plimovanje trdne Zemlje, oz. je minimalen.

• Title: Modelling of solid Earth tides in 3D positioning points of the combined geodetic network

Abstract

In this diploma thesis, we present the impact of solid Earth tides on the 3D point position modification of the new combined 0. order geodetic network. We described the purpose of point establishing and stabilization as well as the intended equipment to be installed at five points of the combined 0. order geodetic network . We also introduced a basic theoretical background of solid Earth tides, described different models of tides and emphasized the accountability of solid Earth tides in conjunction of terrestrial coordinate system with vertical coordinate system. We modelled the solid Earth tides on the example of two points of the 0. order network, Areh and Prilozje. We have shown the 3D position modification and the modifications of the gravitational acceleration which occurs due to the impact of celestial bodies attraction. The modifications are shown for two different seasons. We found out that the solid Earth tides have greater impact on the position modification during summertime when there are also the amplitudes of up to about 35 cm of the vertical component. It is also important that the area of Slovenia has no effect on modifications due to solid Earth tide or it is minimal.
