Problem statement. At present, promising multi-satellite communication systems are developing at an intensive pace. These include projects O3b, Kuiper Systems, OneWeb and Starlink. Such systems are characterized by high noise immunity due to the presence of an excessive number of satellites visible from the location of the ground subscriber. Nevertheless, the presence of terrestrial sources of interfering radio emission in frequency ranges that coincide with the operating frequencies of satellite systems can lead to disruption of their performance. At the same time, from a practical point of view, the task of estimating the size of the zone of possible disruption of the multi-satellite communication system becomes relevant.

Purpose. Development of a methodology for estimating the area of possible disruption of the functioning of a multi-satellite communication system with respect to a ground source of interfering radio emission.

Results. The paper proposes a technique that makes it possible to estimate the size of the zone of possible disruption of the functioning of a multi-satellite communication system with respect to ground sources of interfering radio emission. The proposed methodology was tested on the example of the Starlink multi-satellite communication system. So for Starlink of the first stage of deployment with a confidence level of 0.8, the radius of the zone of disruption in the case of interference along the main beams of the satellite antenna pattern will be at least 142 km, and with interfering effects along the side beams, 1634 km.

Practical significance. The developed technique in practice will make it possible to quickly assess the size of the zone of possible disruption of the operation of noise-immune multi-satellite communication systems with respect to a ground source of interfering radio emission.
