The article considers the effect of non-Stationary unintentional interference on the earth station of a satellite communications system with Multi-Frequency Time-Division Multiple Access. The influence of non-stationary interference and white Gaussian noise on the earth station reception channel is compared using simulation modeling. The simulation model takes into account the effect of unintentional interference on the synchronization subsystem and the allocation of the boundaries of the transmitted packet of the receiver of the earth station of the satellite communication system. The probability of a bit error was used as a criterion for the quality of the satellite channel operation. The article shows the dependence of the protective ratio on the ratio of the preamble length to the packet length under the influence of pulsed interference. The obtained dependence can be used to assess the noise immunity of an earth station in a satellite communications system under the influence of pulsed interference.
