Abstract :
It is accepted to consider low frequency noise as radio interference. Actually it is a very useful means for diagnosis of the medium in which it is excited and propagated. The results of research of low frequency emissions (0.1-20.0 kHz) obtained from the "Intercosmos" satellite data have shown that the low frequency emissions bear information on parameters of the environment: about variations of energy particle fluxes in the area where the noise is excited, about parameters (density and temperature) of plasma in which it is propagated, about level of disturbance and turbulence of plasma, and about geomagnetic and solar activity level.
