The article discusses basics of electromagnetic fields monitoring in the frequency range from 1 kHz to 30 MHz. Registration methods of experimental data processing obtained by ionosonde "TOMION" are provided. When using the global network of digital ionosondes "TOMION" will be able to monitor ionosphere condition in the passive mode of oblique radiosounding, as well as to perform the short-term (immediate) forecast of stable radio communication and electromagnetic pollution control on a global scale.
The article is a brief description of the software developed for operation ionosonde "TOMION" in an accelerated mode active vertical radiosounding of the ionosphere.

This study is devoted to the development of new techniques for the research of the ionosphere state. This paper describes the new approaches to development and implementation of the methods for remote radio sounding of the ionosphere on the basis of the world technological advances and the most innovative methods of data analysis, applied at Ionospheric Observatory of Tomsk State University using data processing software Dynasonde 21.
