Methodology positional controlling of communications aerial platform in FANET in the minds of influction of radio electronic countermeasures

Abstract

FThe article considers the method of controlling the positioning of communication aerial platforms in the FANET network in the conditions of radio-electronic countermeasures to achieve the target function: increasing the accuracy of managing the navigation parameters (movement) of communication aerial platforms (reducing the deviation from the target trajectory). The work shows the process of controlling the parameters of FANET communication aerial platforms positioning in the process of deployment, operation, and control of the rotation process of the main node of the air communication subnet. The deviation of the navigation parameters of the communication aerial platforms was estimated using simulation modeling. The process of determining the coordinates of the communication aerial platforms based on the received signals (probes) on the main transmission channel has been formalized. The article shows the use of a backup channel based on LoRа, to maintain control in conditions of loss of GPS signals, which can become the basis for estimating the energy consumption of the communication aerial platforms network in the process of information exchange. The process of adaptive adjustment of the navigation parameters of the communication aerial platforms is proposed to be carried out using the Kalman filter. The scientific novelty of the method consists in the application of a scientifically methodical apparatus of trigonometric transformations of the channel matrix and calculation of azimuthal and elevation angles for additional correction of navigation parameters by positioning the communication aerial platforms relative to the mobile base station. This approach allows you to achieve optimization of the target functions of the positioning management process and ensure real-time decision-making. The results of simulation modeling confirm the possibility of providing a smaller deviation of navigation parameters up to 30 m compared to the known solution using the PSO algorithm 340–400 m in height.
