Abstract. This article examines approaches to improving the reliability and resilience of information exchange for unmanned systems, taking into account the presence of external interference. The primary issue addressed in this article is the analysis of natural and artificial factors that may affect the operation of data transmission channels. Emphasis is also placed on the impact of artificial electromagnetic disturbances. The paper’s scientific innovation is that it considers the unmanned system as a multi-agent environment. The agents are the operator, the aircraft, and the external environment. The goal of the study is to improve the reliability of the data exchange channel by implementing Visible Light Communication technology. To achieve this goal, the authors formalized quantitative control assessment methods, developed a structural and functional model of the control system, and conducted simulation tests to assess risks. An analysis of experimental data and computer modeling demonstrated that Visible Light Communication, operating in the infrared range, provides a stable information exchange channel over a distance of up to 3 kilometers. This result demonstrates the potential of using this technology to build a noise-resistant and secure information exchange channel for unmanned systems.
