Currently, various robotic systems, including complexes with unmanned aerial vehicles (СUAV) of different classes and purpose, are widely used. At the same time, in order to increase the efficiency of application, as well as to ensure the safety and reliability of expensive robotic equipment and avionics (avionics), the task of providing over-the-horizon control and data transmission by means of information relaying between the UAV and the ground control station (GCS) using the orbital frequency resource of modern domestic orbital groups (OG) of spacecraft (SC) in high orbits becomes particularly urgent. This article presents a concise analysis of the technical characteristics of transponders onboard both existing modern domestic spacecraft and prospective spacecraft that allow transmitting high-speed information flows in the interests of complexes with UAVs, presents the results of calculations of achievable data transfer rates from UAVs, and also identifies the existing restrictions on the intended use of UAVs and prospects for further development of this topic. The purpose of the article is to obtain estimates of the potential speed of transmission of target information from the UAV to the GCS via the spacecraft using existing and prospective OG spacecraft, taking into account the analysis of the technical characteristics of the spacecraft transponders to ensure the effective functioning of complexes with UAV, the formation of requirements for prospective spacecraft to further increase the speed of transmitted data. The practical significance of the article is the possibility for developers and operators of UAV to use calculated estimates of data transfer rates for the formation of UAV flight tasks, the distribution of target loads on UAV as part of a group, taking into account the capabilities of UAV in terms of tactics for their intended use in the far zone beyond the horizon. In conclusion, the results of analysis and calculations are presented, conclusions are drawn, and relevant suggestions and recommendations are formed.
