As showed results of the experimental measurements, stationary plasma thrusters (SPT) of space vehicle are an electromagnetic radiation source in broad range of frequencies. This radiation under certain conditions can make essential impact on quality of functioning of radio communication channels of the Earth-SV. On the basis of statistical analysis of results of the experimental measurements of radiation a SPT phenomenological mathematical and simulation models of radiation a SPT are developed. It is led validation the given models. For various values of signal-to-noise ratio and a signal-pulse noise the quantitative characteristics of an interfering signal effect on information transfer reliability for digital communication channel with BPSK are determined. Effect of interference in the form of the total an AWGN and random pulsing sequence on channels of phase and symbol synchronization is sized up.
