The relevance of the work is due to the rapid increase in the number of radio-electronic devices in near-Earth space, which leads to a more complex electromagnetic environment. The problem of electromagnetic compatibility is of particular importance in the context of the interaction of spacecraft and ground stations, where interference can disrupt the quality of communication and the operation of systems. The occurrence of interference due to the intersection of the operating frequency ranges of transmitters of various spacecraft requires the development of methods for quantifying such interference and establishing requirements for their operation parameters.

A methodology for analyzing electromagnetic compatibility for satellite systems operating in common frequency bands has been developed. An algorithm for calculating the interference level at the input of an Earth station receiver is proposed, taking into account the parameters of the target and interfering spacecraft, signal propagation losses, atmospheric effects, and antenna patterns. The analysis of scenarios with the presence and absence of interference was carried out, which made it possible to assess the energy potential of the radio link and determine the conditions for ensuring electromagnetic compatibility. The technique demonstrates high practical importance for the design and operation of satellite communication systems.
