Item Modelling of atmosphere time state using regular observations of TEC parameters(Lviv Polytechnic Publishing House, 2016) Peresunko, Bogdan; Nedohonova, Anastasiya; Kramarenko, Sergiy; Lviv Polytechnic National UniversityThe use of a network of active reference stations to establish the numerical characteristics of the Earth's ionosphere allows to create an effective ionosphere monitoring technology on a regional scale, designed to address the scientific challenges of space weather and practical problems coordinate support geodetic accuracy class. In this work we decided the task of recovering the time state of the ionosphere using regular observations of the TEC parameters (VTEC – Vertical TEC) for permanent station SULP. The authors have described one possible way of solving this problem, which is based on mathematical modeling with using degree polynomials and trigonometric Fourier series. Degree polynomials describe the trend of function, whereas the trigonometric Fourier series in order to better simulate the fluctuation.Item Toward geodynamic studies and GNSS CORS measurements: West Ukrainian GNSS network data processing using Bernese v5.2 software(Видавництво Львівської політехніки, 2017-12-23) Golubinka, Iurii; Kramarenko, Sergiy; Lompas, Oleksandr; Marchenko, Dmytro; Lviv Polytechnic National UniversityPresented study is organized to enhance the services provided by number of GNSS stations in Western Ukrainian region, which are mainly a network of Continuously Operated Reference Stations (CORS) established in different years by different institutions, and improve the efficiency of the GNSS data usage. The main objective of the study is to compute CORS velocities, using available three years’ data, establish an automated procedure of further data computation. The interpretation of the velocities together with geological data for the region and estimation of the crustal movement as well as extension of the studied region to all Ukrainian area
