Russia is expanding the production and deployment of advanced navigation modules on its attack drones by integrating larger antenna arrays to resist electronic warfare. The hardware upgrade aims to complicate ongoing efforts by opposing forces to disrupt incoming weapons by interfering with the satellite signals they depend upon for navigation.
The navigation equipment, known as Kometa and produced by VNIIR-Progress, uses multiple receiving elements to maintain satellite connections when opposing forces transmit interference. These components, commonly called patch antennas, help distinguish legitimate navigation signals from electronic interference, allowing drones to retain their intended flight paths. Russia has already deployed versions containing 16 elements and is preparing manufacturing capacity for configurations containing 20 receiving elements. However, Ukrainian specialists identified significantly larger 32-element arrangements on Shahed attack drones during recent attacks against Kyiv.
Key takeaways
- Russia is increasing the number of antenna elements on attack drones to resist electronic warfare and satellite signal jamming.
- Ukrainian specialists discovered massive 32-element antenna configurations on Shahed drones during attacks on Kyiv.
- Per Ukrainian intelligence, Russian defense manufacturers have ordered more than 100,000 modules across various configurations.
- Ukrainian defense units are developing alternative countermeasures, including multi-band jamming and coordinate spoofing systems.
Scaling Production Across Multiple Weapon Platforms
Serhii Beskrestnov, an electronic warfare specialist advising President Volodymyr Zelenskyy on defense technology, detailed how the physical scaling of these components directly impacts operational capabilities. According to Beskrestnov, a larger number of elements enables the antenna to suppress a greater number of electronic-warfare signal sources. The 32-element configuration reportedly combines two separate 16-element arrays, allowing the equipment to operate across different satellite navigation frequencies.
These upgraded Kometa navigation systems have appeared across a broad inventory of Russian hardware, including Geran drones, guided aerial bombs, Iskander-M and Kinzhal missiles, and the newer Filin cruise missile. According to intelligence gathered by Ukraine, Russian defense manufacturers have ordered more than 100,000 modules in different configurations, covering several categories of guided weapons. The immense scale of these purchases indicates a strategic intent to distribute improved navigation protection across multiple distinct weapon platforms.
Ukrainian Countermeasures and Spoofing Tactics
Despite the implementation of larger antennas, Ukrainian specialists maintain that these hardware enhancements do not render Russian drones completely immune to electronic interference. The effectiveness of each Kometa configuration ultimately depends on its specific antenna arrangement, receiving elements, and onboard processing algorithms that separate true satellite signals from background interference.
After studying a 32-element antenna acquired through secondary weapons markets, Ukrainian defense personnel claim to have devised strategies to neutralize the hardware. Alkhimik, commander of Ukraine's Night Watch unit, noted that deploying a dual-system approach covering both the L1 band and the L2/L5 bands could successfully jam the multi-element antenna. An alternative defensive tactic involves satellite spoofing rather than brute-force signal overwhelming.
Fly Group Ukraine has engineered connected devices capable of transmitting fabricated coordinates to approaching Russian drones. Anatoliy Khrapchynskyi, development director at Fly Group Ukraine, explained that this technique exploits onboard autopilots by gradually altering course data without triggering internal manipulation alerts. Consequently, the aircraft steers itself away from populated areas into designated safe zones. Even so, the long-term reliability of these countermeasures remains uncertain as defense developers on both sides continue iterating on their respective electronic warfare technologies.
