TL;DR: In this paper, the main results of GPS/GLONASS radio sounding of ionospheric disturbances of natural and anthropogenic origin are presented and a review of studies of ionosphere effects carried out in ISTP SB RAS is presented.

TL;DR: In this paper, the form and dynamics of large-scale traveling ionospheric disturbances (LS TIDs) of auroral origin were investigated using GPS-arrays whose elements can be selected from a large set of GPS stations forming part of the International GPS Service network.

TL;DR: In this article, the authors presented data from first global positioning system (GPS) measurements of global response of the ionosphere to solar flares of September 23, 1998 and July 29, 1999 and found that fluctuations of total electron content (TEC) obtained by removing the linear trend of TEC with a time window of about 5 min, are coherent for all stations and the line of sight to the GPS satellites on the dayside of the Earth.

TL;DR: In this paper, basic properties of the mid-latitude traveling ionospheric disturbances (TIDs) during the maximum phase of a major magnetic storm of 6 -8 April 2000 are shown.

TL;DR: In this article, an analysis of the ionospheric response to solar flares was performed using phase measurements of the total electron content (TEC) in the ionosphere using an international GPS network.
