The active use of unmanned aerial vehicles (UAVs) in various fields of activity requires the organization of reliable communication channels over long distances. Line-of-sight radio channels are limited in range, which necessitates the use of satellite systems to control aircraft-type UAVs at a considerable distance from the operator. The purpose of the work: to study the capabilities of satellite communication channels (SS) using the example of low-orbit groupings for UAV control using a comparative analysis of the characteristics of SS parameters. Results: based on the analysis of the orbital parameters of satellite groupings (SG), the technical characteristics of channels and communication technologies, a comparative assessment of the possibilities of transmitting information to UAVs is given according to the criteria of communication quality, information transmission rate, time delay of the radio signal, efficiency and continuity of the communication session. It has been established that modern low-orbit CRS are capable of providing high speeds (up to 100 Mbit/s for a single subscriber) and a relatively low signal time delay (20ms), provided that antennas based on phased array antennas, laser inter-satellite communications, and spatial channel separation (HTS) technology are available. Practical significance: the results of the study provide practical guidance to the organizers of communication with aircraft-type UAVs when choosing physical channels based on low-orbit groupings in terms of range, quality, efficiency and availability of communication sessions, taking into account the prospects for the development of domestic SG. Scope of application: control systems for unmanned vehicles used in telecommunication systems for monitoring and ensuring the security of various facilities.
