Ukraine is developing a radio complex to catch Russian S-400

Work on the development of the Gekata, the Ukrainian radio-technical intelligence complex, is actively progressing at the Ukrainian research and production center Infozakhist, as reported by the firm’s director Yaroslav Kalinin. 

As divulged by Kalinin, the company is currently engaged in the intra-firm experimental application of the prototype, keeping it restricted to provisional usage for practical problem-solving. 

“Our project has finally managed to take off and we’re in the phase of ascending into further complexities. Just like in any other experimental format, we’ve come across a few roadblocks that require resolution,” expresses Kalinin.

On being queried about when Gekata would have the ability to identify Russian anti-aircraft missile structures in proximity to Ukraine’s borders, Kalinin assures that they have already registered preliminary successes in this arena. However, he was quick to point out that this success is confined to a separate apparatus and not the whole system. 

“We have started receiving and processing the initial signals, and are now constantly expanding our competencies to ensure a complete situational awareness chain from pinpointing enemy ground station coordinates in real-time to fostering weapon action planning flexibility”, Kalinin expansively puts. 

Let’s not forget, that Gekata’s radio-technical intelligence system was first unveiled at the Arms and Security Exhibition in 2021. This system was built on the PD-2 drone, a product of the Ukrainian firm Ukrspecsystems, and its flight tests commenced in December 2021.

The functionalities of this complex are wide-ranging in radio-technical intelligence and are dedicated to detecting enemy radars, radio-electronic protection mechanisms, air defense systems, and aircraft. This project, in turn, is expected to substantially aid the Ukrainian military forces.

What do we know about Gekata?

The Gekata complex boasts a formidable detection range of 450 km, allowing its drones to surpass the reach of Russian air defenses. This impressive range means the drones can perform reconnaissance missions across the entirety of Ukraine, notably including its temporarily occupied areas and Crimea. 

What’s more, the Gekata complex is designed with stealth in mind. It emits no signals during operations where it can track a PD-2 drone, even when the drone ventures 200 km from the front line. Remarkably, the PD-2 can still provide a clear picture of what’s happening 250 km deep into the territory. 

The capacity of the Gekata complex is equally impressive. It’s capable of monitoring a whopping 200 targets all at once, storing the data it gathers or transmitting it live, depending on the requirements. All of this can be accomplished even during utmost ‘radio silence’, or when in autonomous flight.

The operational efficiency of such a complex is heightened by the fact that a single operator can manage its functions. It demands less energy compared to terrestrial RTR systems, making it an eco-friendlier alternative. Its short setup time and highly mobile design are also notable aspects touted by the manufacturing company.

Features of the Gekata complex

The Gekata operates within a frequency range of 2-18 GHz, which is standard in the base model. It relies on a superheterodyne type receiver, offering an immediate review bandwidth in real time of 800 MHz. 

Allowing for a total of two independent channels on a hardware level, it provides a snapshot bandwidth of one channel at 400 MHz. A single signal carries a dynamic range greater than 72 dB, with the capacity for a full 360° visibility range instantaneously along the azimuth angle.

As previously stated, it can track up to 200 moving targets, utilizing a coordinate determination method composed of TDOA+AOA.
