The cosmic dust factor in the Implementation of global decameter range telecommunication systems

Studies on ionosphere modification using heating facilities include results that turned out to be significantly lower than expected. For example, the problem of forming artificial field-aligned irregularity based on excitation of an ionospheric waveguide has not been fully solved. One of the reasons for such a discrepancy may be the presence of cosmic dust in the area of ionospheric impact. To test this hypothesis, a new method for studying the influence of cosmic dust on experiments on active impact on the ionosphere has been developed, which uses the results of research carried out by third-party organizations on the EISCAT heating facility. We use the method of multi-position diagnostics of field-aligned irregularity based on SDR (Software Defined Radio) technology and a natural source of cosmic dust - the Geminid meteor shower. As a result, it was experimentally shown that the presence of cosmic dust in the area of active influence on the ionosphere leads to a change in the characteristics of artificial field-aligned irregularity of the ionosphere and, consequently, the parameters of transcontinental ionospheric communication channels.
