    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 University
    The 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.
