Abstract
Investigation of protection of the control command transmission channel from interception in unmanned aircraft
Incoming article date: 08.11.2025The article presents the results of a study of the security of the command transmission channel for unmanned aircraft (UAV) using the example of an FPV drone. The research was carried out in an anechoic shielded chamber of a specialized landfill with certified measuring equipment. The results of measurements of the spectral panorama and the possibility of passive interception of signals in the radio are presented. The relevance of ensuring safe operation of the UAV is shown, as well as the vulnerability of the ELRS protocol to control interception. Recommendations on the use of cryptographic algorithms to neutralize security threats are given.
