Description: The method of noise-immune communication channels with a reduced ionospheric plasma density for spacecraft formation is considered in the article. As a tool for the formation of such channels, the use of artificially created plasma of localized discharge is proposed. It is established that this plasma is characterized by high radiation intensity, rather large dimensions and uniformity, both in the longitudinal and radial directions, the absence of electrons and ions ambipolar diffusion. Proposals have been made to expand the range of radio communications with minimal energy costs.
