Su-57 is testing a new version of the cryptographic communication system

Tests of the latest version of the communication, navigation and recognition system on the fifth-generation fighter Su-57 are reported. We are talking about the OSNOD system, which is distinguished by high cryptographic protection and noise immunity.

Information Agency TASS, referring to the head of the Scientific and Technical Center "Flight" Alexei Ratner, reports that a flight modification of the OSNOD was developed specifically for the Su-57 fighter.

In particular, the system uses error-correcting coding with data recovery. The enemy is deprived of the opportunity to intercept the information flow that goes from one aircraft to another or from an aircraft to the ground and vice versa.

According to Alexei Ratner, the system undergoing testing is one of the most noise-proof communication and navigation systems.

Recall that on the eve of the American edition of The National Interest, material was released in which the authors announced that the purchase of the Su-57 aircraft by the Russian Ministry of Defense means "preparation for war." By the same logic, any Pentagon procurement of military equipment, including contracts for F-35, should also be regarded as the preparation of the United States for war. In fact, NI reporters, apparently, are not very familiar with the expression “If you want peace, prepare for war” - it is in this vein that armed forces exist in different countries of the world.

This is excellent, I really hope that this system will not be exported or there it will be greatly truncated

[Thrall]

That's what I’m thinking about now. And why shouldn’t the Turks still buy a few F-35 from the USA, and then exchange with Russia for the same number of Su-57. It would be a star-haired mega-trolling

Everything will be the other way around, the Americans will get access to our Su-57 if the Turks buy it. Erdogan is not eternal, and even now he is our "friend, while there is no dashing."

[Ravil_Asnafovich]

I remember that during the time the French made it so that mirages did not take off in Iraq, maybe we need to come up with this.

[Vladimir16]

And why not Belarusians?
Now build relationships with mattresses and buy.
And then, as you planned, change with Russia.
As you said earlier, you will exchange "with citizens of other states."
Are you ready for mega-trolling?

[Avior]

States refused to sell the Turks f-35.

Who needs this? Yes, and why? This is not necessary (trolling has already been done about missiles, and the S-400 has taken its toll).

No need to get a sample of the modern high-tech weapons of a potential enemy?
Scouts and aircraft designers looked at each other and smiled now

[SERGEY SERGEEVICS]

Since these are not secret F-35 technologies, we and many other countries already know these technologies. Scouts already even laughed

[Herman 4223]

The Turks did not refuse from f35. They don’t just sell them.

As I said earlier, at the output, the serial SU-57 will be as close as possible to the 6 generation fighter. In any case, if you remember that the lizard is positioned as a fighter of the 5 generation, then the SU-57 will be of this generation with more than one plus. And where there are 76 machines, there the contract can certainly be reconsidered in favor of increasing the series, which will undoubtedly be.

I agree. I watched at the MAX flight of the Su-57. On aerobatics, the Su-35 nervously smokes on the sidelines. This is only the power of the first stage

Yes, it flew off cool, I agree!
Greetings!
Meanwhile,

A radical US Air Force plan for a promising fighter could lead to a new aircraft within five years ... the NGAD program should take an accelerated approach to developing small series of fighters with the participation of several development companies, like the aircraft of the "hundredth series" (with the F- 100 by F-106), built in the 1950s ...

, that is, the penguin is no longer the best ..
An urgent new cut of the dough and small series of fighters, most importantly faster, faster, otherwise the Dry ones are already actively flying

[voyaka uh]

", that is, the penguin is no longer the best." ///
----
Penguin - a replacement for the F-16. Fighter bomber.
A new one should replace both the F-15 (outdated) and the F-23 (there are few of them).

[Orkraider]

Welcome.

F-23 (there are few of them).

Would you like to write F-22?

[voyaka uh]

Right Typo. thank

Gentlemen!
They promised the passage of the SU-30 group at a speed of 80 km / h at an altitude of 100 meters.
Was it or not?
Can you scare the link to the video?

There was a passage, but it was carried out as part of the Su-30SM solo flight, it seems Andrei Alekseev.
No video, alas.

Just drove up to the MAKS and Su-3o flew quietly so straight on the bus. I saw only one. Eh. It was beautiful

[Constructor68]

The ability to demonstrate EVP on both aircraft is the same.

[Pavlov Sergey Alexandrovich]

Yes, Sergei Bogdan also commented that the aircraft is very frisky even on the engine of the 1st stage. Perhaps this is due to the widespread use of carbon fiber based composites, etc. those. a significant reduction in the weight of the airframe with a similar engine thrust with the su-35, the specific moshiness increased plus the new flight control system did the trick ... anyway, the su-35 was made using technology 30-40 years ago and the whole spectrum was used on the su-57 technologies available to our auto manufacturers.

[Rwmos]

Why do they need them Communication standards, as well as recognition of friend or foe - each country makes for itself, so this system will not go beyond the hill - it simply cannot. This is how the Germans would sell Enigma - also a standard of secure communication ...

[Mountain shooter]

Getting ready, getting ready ... Don’t worry about us ...
Gentlemen from NI and their readers.

Su-57 is testing a new version of the cryptographic communication system

Do they want to defend themselves from the Krypton attack ???
Digital technology, digital coding ... is this something new ??? For a long time and everyone is doing it!

[Glory1974]

Digital technology, digital coding ... is this something new ??? For a long time and everyone is doing it!

There are certain problems with the Doppler effect. At high speeds, a frequency change and a mismatch of classified equipment occurs.
I don’t know how it is now, but back in the 1999 year, during the bombing of Serbia, all NATO aircraft spoke in open mode and all conversations were tapped by our radio intelligence without any problems.
Therefore, in aviation, cryptographic protection is used, but in the telephone mode, the thing is new.

In the telephone mode, everything has long been "digitized - encrypted" ... protocols of exchange of all inter - inter, in short, long distance communication is a digital code. The analogue survived over very short distances!
Protocols / ciphers are changing, becoming more complicated to increase exchange rates and stream compression. Those. nothing new.
There are protocols \ ciphers of a high degree of coding, noise immunity ....
Those. this is a normal process of improvement, as a rule, this is complication ... there will be a quantum! This is normal.
I have seen this for many years ... therefore, I no longer perceive it as something special, super new. This is all not something, on new principles, hitherto unknown to science.

There are certain problems with the Doppler effect. At high speeds, a frequency change and a mismatch of classified equipment occurs.

To decode the encoded signal from the ground, the aircraft can make a dynamic frequency correction of its on-board declassifying equipment. The correction depends on two vectors: the speed of the aircraft relative to the ground and the direction to the ground transmitter.
The aircraft knows both vectors and can calculate the correction necessary to declassify the received signal from the ground-based transmitter in real time.
And for transmitting the encoded signal from the aircraft to the ground (so that the earth can decrypt the message received from the aircraft in real time), you can also make a similar dynamic correction, but already the frequency of the signal radiated to the ground from its on-board classified equipment.

[Glory1974]

Svetlana, well done. Nice to talk with you.
But I want to note:

The aircraft knows both vectors and can calculate the correction necessary to declassify the received signal from the ground-based transmitter in real time.

he knows the amendment. But since the frequency is floating, it can not receive a digital message on-line. Either this happens with a delay that is unacceptable at speeds in aviation, or only after the information is compressed and the performance equipment shoots it.
Therefore, pilots conduct telephone communications (voice transmission) in analog mode, and data exchange (target designation, situation data) in digital. And this data exchange is classified

[Thrifty]

Maybe, in general, then, let our "clever men" lay out the classified information on the plane in the public domain - in full? Why write that? ?? "my language is my enemy, this aphorism is most relevant in Russia now.

Well, we are. We are a little scared so that only the US military budget equals the national debt

[Angrybeard]

I wonder in what generation the connection will become quantum. Here it is very difficult to intercept and decrypt) in theory there are no obstacles there, you change the state of an entangled quantum at one point, instantly you get the same state at another. But you need a regular communication channel, and noise-tolerant.

[ccsr]

In particular, the system uses error-correcting coding with data recovery.

As early as the eighties of the last century, it found practical implementation in some radio communication systems. It is not clear what is new here.

The enemy is deprived of the opportunity to intercept the information flow that goes from one aircraft to another or from an aircraft to the ground and vice versa.

This is generally nonsense, because if there is radiation and there is a receiver, then the enemy can always create a system for radio interception. Another thing is whether he can quickly decipher the entire flow of information - but this is from another area, the capabilities of which are determined not by us, but by the enemy.

According to Alexei Ratner, the system undergoing testing is one of the most noise-proof communication and navigation systems.

Let's hope so, and at the same time we are proud of our developers - as they say, "you can't drink skill."
