Informative Safety of Unmanned Aviation Systems Radio Communication Channel

Abstract

An analysis of navigation and command-telemetric radio channels is used for exploitation of unmanned aviation systems are proceeds. The classification of radio channels vulnerability is tied to the modes of unmanned aerial vehicles control and their safe exploitation key terms. The criteria of flight mission feasibility and applicability of the different control modes are set in the conditions of violation at the radio channels data communication. The signs of successful flight task processing are the aircraft returning and landing to the set point, absence of distortions or rejections of preset flight trajectory, regular payload functioning. Each of these criteria can be broken when hindrances and interferences in the radio channels are present. Composition and setting functions of unmanned aerial vehicles control radio channels depend on the control mode. In-process distinguished manual control mode from earth in the zone of visual control, manual control mode via the feedback video channel, automatic control mode by an aircraft by on-board autopilot with constantly operating bilateral radio channel of telemetry and automatic control mode by the commands without permanent telemetric control. The first two modes envisage the permanent participating of the controlled from ground pilot in the control loop and due to it does not depend on suppression of satellite navigation radio channel. Suppression of radio management channels for these modes usually ends with abnormal finishing the flight. Hindrances and suppression of radio channels at automatic control modes can result in deviation of trajectory from the preset one or unsatisfactory work of the payload. Conclusions contain newest further suggestion on the unmanned aerial systems radio channels security. In the modes of visual hand control the probability of extraneous interference can be diminished by directed antennas. To increase the security at the automatic flight modes it offers to use the satellite navigation data authenticity analyzer with permanent comparison between the satellite data and calculated navigation data.
