Su-57 will encode its data through AI and noise-immune transfer

The Sukhoi Su-57 will encode its data transfer using artificial intelligence [AI] generated noise-immune transfers. Most likely, in the future, we will witness just such a modernization of the Russian Felon. At least that is the impression left by the latest press release from the Russian corporation Rostec.

• New Czech simulator of F-15E provides high level of immersion
• New world-class ECRS Mk2 radar for British Typhoons begins testing
• F-22 pilot boarded two-seat Russian-origin Su-30, flew a mission

Rostec announced on April 21 that, based on artificial intelligence, it had developed a new communication system for combat aircraft of the fifth and next generation. The developer is the Russian company Ruselectronics, which is part of the Rostec holding. The new AI communication must ensure the encoding of data and its transfer between platforms, both in the air and on the ground.

AI-based technology enables noise-immune coding through the use of parallel channels. This is the “wrap” of the technology. Its structure includes multiple interleaving of symbols, time synchronization during transfer, simultaneous transmission of data in all directions [air-to-ground or air-to-air], and increasing the range of transmitted data.

First signals

The idea of the so-called “second pilot” in the Su-57 is not new. Already at the presentation of the first prototypes of the fighter, Russia announced that their Su-57 would have to have both an unmanned version and artificial intelligence. The AI-based communication system may have already been tested.

We recall that on October 21, 2022, a new version of the Su-57 was tested by the United Aircraft Corporation [UAC]. The test took place near Moscow. Then the UAC announced that they were testing new avionics, not a new fighter design. The new avionics allowed the pilot to engage in another operational role while in flight.

According to reports from the UAC at the time, the tests focused on communication in the cockpit between the onboard computer, the radar, and the data read by it, as well as between the onboard computer and a ground platform. The idea that the UAC presented at the time was that in flight the aircraft could decide what weapon and when to use it if the radar picked up an enemy object in the air. Even then Mr. Yuri Slyusar, Director General of UAC said that the next Su-57 will be navigated and controlled “by a set of intelligent sensors”.

A signal that Russia is preparing its fifth-generation fighters for the next level of performance was the integration of a new onboard architecture of the Su-57. This happened in February of this year. The UAC then said that it was of the open type. Besides the Su-57, the Su-35 is also slated to receive this upgrade. According to opinions in the Russian media, the new on-board architecture will allow for improved communication specifically between the Su-57 and Su-35, and will allow “automatic decision-making at all stages of the flight related to the dynamically changing environment.

The AI communication complex

These are the two signals that have arrived from Moscow in the last six months and are related to the development of the Su-57. The announcement of the new AI-based communication system only shows that Russia is working on upgrading its fighter jets with sensors that should significantly change their performance.

Ruselectronics’ AI communication system has already been patented and has been awarded a gold medal by the Moscow International Salon of Inventions and Innovative Technologies “Archimed-2023”.

Rostec announced that the AI complex includes many different components and subsystems. The company highlights the presence of computing devices, interleaves and deinterleaves, radio frequency antenna matching devices, digital signal processing units, error-correcting encoding, and decoding devices, as well as an antenna and bus global navigation satellite system signal receiver for digital signal processing and synchronization.

Alexey Komyakov talks about the developed AI communication system. In his words, radio electronics are increasingly becoming a key differentiating factor for fifth-generation fighters. The new system will solve many tasks together with the rest of the fighter’s avionics. The AI technology that Rostec has announced as developed is expected to be part of the latest Russian S-111 communication system.
