Тенденції еволюційних змін у приймачах сигналів супутникових радіонавігаційних систем високоточних засобів повітряного нападу

Abstract

The article presents the results of research conducted on-board navigation systems of unmanned aerial vehicles and missiles used by the russian federation against Ukraine, using the example of «Shahed-136» (Geran-2), X-32. The changes that have occurred in the structure of antenna systems and signal receivers of satellite navigation systems are analyzed.

The trends in the further development of interference-protected navigation receivers with small-sized adaptive antenna arrays are studied. 3D models of antennas created using ANSYS software are presented. The work includes a parametric and structural analysis of navigation receivers, with special attention paid to antennas with a controlled radiation pattern. The article draws attention to the further development of protection of navigation receivers from interference, which consist in increasing the number of antenna array channels, as well as in improving interference protection algorithms.

The conclusions draw attention to the interference protection of receivers, which consist of multi-band and integration with inertial modules. Trends in the development of antennas with a controlled directional pattern are identified, which are aimed at reducing dimensions while maintaining efficiency, improving the formation of the directional pattern, integrating computing modules into the antenna body, increasing the role of algorithmic support (beamforming, calibration), increasing antenna arrays, increasing the signal-to-noise ratio, reducing the probability of GNSS fixation los, tracking stability in the presence of a complex spectrum of interference.
