Yarema N. Modelling of the system of the Earth’s fundamental parameters based on geodetic and astronomical data

The Earth as a planet represents the research object. The main objective of the presented dissertation is the modelling of the Earth's fundamentals based on the geodetic and astronomical data. Methods of study are based on the developed methodologically rigorous approach of the modelling of the system of the Earth fundamental parameters at adopted epoch. Scientific novelty consist in the adjustment of the Earth's fundamental parameters based on the developed rigorous approach, computation of the average value of the Earth's gravity potential related to the mean ocean surface, estimation of the secular variations of basic astronomical and geodetic parameters. The results of this study are the consistent set of the Earth fundamental parameters at epoch 2000 together with their secular variation.The results of research is used of Ukrainian State Aerogeodetic Enterprice for the control of quality of transmission of the Baltic 1977 vertical system on island Zmijinyj.The results have to be used in geodesy.
