Ukraine Exposes Foreign-Made Components Behind Russia’s Anti-Jamming Tech Used in Missiles and Drones

Ukraine’s Defense Intelligence Directorate (HUR) has identified foreign-made components used in the production of Russia’s Kometa anti-jamming navigation modules, which are installed in Russian missiles, attack drones, and guided aerial bombs.

According to HUR from Ukraine’s military intelligence, the modules are designed to protect onboard navigation systems against electronic warfare interference, allowing Russian weapons to maintain navigation capabilities in contested environments.

The Kometa system uses controlled reception pattern antennas, which can suppress interference by adjusting the antenna’s reception pattern and applying signal-processing algorithms.

According to HUR, a standard Kometa module used in modern Russian missiles, unmanned aerial vehicles, and guided aerial bombs consists of two main components: an antenna array containing a specified number of patch antennas and a signal-processing module based on a programmable logic device.

The system’s resistance to electronic interference depends on the number and arrangement of its patch antennas, as well as the algorithms used to process incoming signals.

By combining signals received through multiple antennas, the module can determine the direction of incoming interference and reduce its impact on the navigation system.

Ukrainian intelligence reported that Russian forces are already widely deploying Kometa modules equipped with 16 patch antennas, while efforts are underway to establish serial production of more advanced 20-element antenna arrays.

HUR also identified the Russian company VNIIR-Progress as the developer and primary manufacturer of various Kometa modifications. The enterprise belongs to the ABS Electro group of companies, which Ukrainian intelligence linked to sanctioned Serbian pro-Russian politician Nenad Popović.

According to the intelligence agency, another company within the same group is responsible for procuring components needed to manufacture the navigation modules. The supply network includes Chinese distributors and sellers of microelectronics, as well as Russian intermediaries involved in obtaining foreign-made electronic components.

To fulfill orders from Russia’s defense industry, VNIIR-Progress uses both its own manufacturing facilities and the production capacities of other companies within the ABS Electro group. HUR also identified the principal customers for Kometa modules as Russian manufacturers of cruise and ballistic missiles, attack drones, guided aerial bombs, and glide munitions.

In a separate investigation published on October 14, The Insider reported that Chinese technology company Shenzhen Xingkai Technology was prepared to supply mesh communication modems to a Russian drone manufacturing facility despite being informed that the equipment was intended for military use.

The investigation found that the company was willing to deliver communication systems to a drone production facility in Alabuga, Russia, where the equipment could be used to support long-range drone attacks against Ukraine.
