Modelling of ionospheric time state using regular TEC observations

Abstract

The use of a network of active reference stations to establish the numerical characteristics of the Earth's ionosphere allows you to create an effective ionosphere monitoring technology on a regional scale, designed to address the scientific challenges of space weather and practical problems of geodetic-class coordinate support. We propose an algorithm to recover the time state of the ionosphere using regular observations of the TEC parameter (VTEC – Vertical TEC) for permanent SULP station. One possible way of solving this problem is based on mathematical modeling using power polynomials and trigonometric Fourier series. Power polynomials describe the trend of function, whereas the trigonometric Fourier series help us to simulate the fluctuation better.
