In the Russian Federation, a jamming system has been developed for low-orbit communication satellites

The Defense Ministry is testing the latest EW systems capable of neutralizing the operation of low-orbit satellite communications systems, such as Iridium, GlobalStar and OneWeb, over a large area, according to News.

The developer of the “Electronic warfare complex for countering satellite systems in low circular orbits” (KRBSS) is the Moscow Radio Engineering Research Institute (MNIRTI, part of the defense industry) with the participation of the Moscow design center of microelectronics JSC NIIMA Progress.

According to military experts, “the priority location for the new“ jamming ”is the Arctic, where it is not possible to use geostationary communication systems (geostationary satellites“ hang ”above the equator and their signal does not reach the polar regions).”

“Some of the elements of the newest complex, including mobile jamming stations, are already undergoing tests, during which excellent results were achieved. The stations not only fulfilled all the tactical and technical requirements laid down in the project, but in some places showed the best result, ”a military source told the newspaper.

He noted that the new system will be put on combat duty in stages.

“The main elements of the KRBSS are highly mobile jamming stations installed on two trucks: they are capable of simultaneously tracking and jamming the signals of several dozen satellites. In the future, the fleet of "stations" will be replenished with products installed on ships, helicopters, aircraft and Drones", - said in the article.

The designers managed to achieve the desired characteristics by using active phased antenna arrays containing a large number of receiving and transmitting elements.

Military expert, former employee of the 30 Central Research Institute of the Air Force Alexei Leonkov: “Most satellite communications systems are based on large satellites with a very powerful signal in geostationary and highly elliptical orbits. But in low-orbit systems, the principle of operation is different, resembling cellular communication. At the receiving point, a signal from several monitored satellites can be received. Therefore, it is necessary to drown not one powerful signal, but a few weaker ones. The main problem is that all channels need to be pressed simultaneously, otherwise the system will be able to find a loophole. ”

Not only in ballet and rockets, we are ahead of the rest. Waiting for comments to appear here, especially from Israel. Someone will argue that drowning low-orbit communication satellites is impossible.

There is nothing to add here, except to say - Bravo. And our "friends" are those overseas. Again, they will start raving about aliens. But I wonder what they are, do they not understand what? After all, making such statements, they sign their own backwardness. In 2013, I was in France (Paris) at an air show, when the SU-35 was flying (piloted by the wonderful test pilot Sergei Bogdan), the whole audience was watching, frozen and hanging their jaws to the asphalt. Every now and then there were replies: This cannot be, it does not happen, and so on and so forth. Up to the statements - the Russians have invented an anti-gravity engine.

[Scoun]

Well, already the British "Senator" American seemingly serious site veterans today are discussing the "topic" that the GDP has an alien advisor and the US has a lizard-like alien and that Russia is making progress in the military industry thanks to alien technologies.
IMHA jamming of low-orbit satellites (as written in the article) is relevant for the Arctic, they can cause interference in the rest of the territory, but the problem of geostationary satellites remains.

You wrote so colorful that you wanted to find on YouTube. Is that it?

With 99% reliability, I can say yes. Only I looked from a different angle, Agree, it's just magic, as if the plane has no weight at all. Like a "fluff" soars.

Isn’t there an option to contact the police? EW just a little bit at once .. And by the way, why in the States are Russian EW systems?

There is such a stray to the browser that allows you to change your location, which allows you to go to banned sites and download movies, music, etc. from closed torrents. When I turn on my flag Dutch)))
So the flag, not necessarily belonging to the country))) Something like this

[GAndr]

Handsome!
That's just interesting, selective jamming, or how? Ideally, it would be to jam only the frequencies on which the enemy's satellites work, forgive the "partners", while not touching your own.

[stayer]

Are there any specialists? Explain to me, if not difficult. Here is the satellite (s) flying. From them, the signal goes to the device (for example, a guidance unit in a rocket). From this, the rocket understands at what point it is and at what place to strike. Our EW system shuts off satellites and the rocket becomes blind. I understand correctly?
PS The fact that no GPS receiver such as a navigator and other trichomies will work in this area is secondary.

These systems jam only low-orbit communication satellites. GPS satellites in mid-orbits and from the surface can not be reached.

[stayer]

What are they doing? In the sense of low-orbit satellites.

[alean245]

The article talks about groupings like Iridium, GlobalStar, and OneWeb. And these are all communication satellites.

[Operator]

The situation is incorrectly presented in the article - EW jamming is not space satellites, but ground / air / sea transceivers of satellite signals with omnidirectional antennas.

If the transceivers are equipped with directional antennas, then the electronic warfare will not cope with its task.

Once upon a time, back in the 80s, I was friends with one of the VKS officers. We often discussed over a glass of tea the achievements of the sun at that time. And since the capabilities of the videoconferencing were unfamiliar to me, then naturally they were also about them. So, in one of the conversations, I honestly asked him this: they say, you never need all of them and that you can do good for the troops. You know, he didn’t even take offense (friends no matter how), but simply and plainly explained that at the first signal from the headquarters, our airborne forces are able to intercept the control of enemy satellites, stop the operation of transmitting complexes (i.e. cut off all space communications), and even broadcast with their help television and radio broadcasts on enemy territories. And he added that broadcasts on the territory of Russia will also be suppressed. I will not argue that all this is true for that time. I'm not to judge. But coming up with such an answer so quickly is worth a lot. Almost 30 years have passed since that conversation. And now I read this news, remember that conversation and think: if they told me about this even then, what can this system actually do today? Well done guys, the right word.

I ask sorry, but in the 80-e years there were no VKS in the plan.

In principle, it is true .., only GPS, GLONAS satellites fly in other orbits.

The name was different and in the "people" they were called the Space Forces of the USSR.
Wikipedia:
In 1964, in order to centralize work on the creation of new facilities, as well as to quickly resolve issues related to the use of space assets, the Central Office for Space Facilities (TsUKOS) of the Strategic Missile Forces (Strategic Missile Forces) was created. In 1970, it was reorganized into the Main Directorate of Space Facilities (GUKOS) of the Strategic Missile Forces.
In order to overcome the contradiction between the interspecific nature of the tasks being solved and the species subordination of military space, the Ministry of Defense of the USSR (USSR Ministry of Defense) decided in 1981 to withdraw GUKOS from the Strategic Rocket Forces and submit it directly to the General Staff. In 1986, GUKOS was transformed into the Office of the Chief of Space Facilities of the USSR Ministry of Defense.
In 1992, the Office of the Chief of Space Facilities was transformed into the branch of the central subordination forces - the Military Space Forces (VKS).
Or here's a quote from Wikipedia: "Deputy Commander of the Space Forces of the USSR Ministry of Defense, Alekseev Eduard Viktorovich."
In general, don’t call it, but it was the USSR Space Forces.

"At the receiving point, a signal from several monitored satellites can be received.
Therefore, it is necessary to drown out not one powerful signal, but several weaker ones "///

They do not jam the satellite (transmitter), but the receiving stations. Before jammers crushed some
one frequency ("BBC - DJ Seva Novgorodtsev", for example),
and now AFAR allows you to jam many Sev Novgorodtsevs at the same time.

How are you going to jam up the antenna?

And who said that the antenna is directed upwards, who said that the antenna does not have side and back lobes, and if the left signal source exceeds the useful one by 160-240db (which is real), then the receiver with real sensitivity in tenths of a microvolt from the parasitic lobe does not will be able to digest a useful signal? In addition, the article notes: In the future, the park of "stations" will be replenished with products, ..., helicopters, airplanes and drones. And this is already not good for enemy products matching their behavior with low-orbit satellites.

It was sarcasm, if not understood. And ask questions to the "professor", he is a big fan of saying something like that on the forum, techno-steam-punk)

I read and cry ... Did you learn physics? .. Most modern communication and navigation systems use noise-like signals with a very large base (LFM, FCM, AIKM, etc.). The receiver has a very large dynamic range in amplitude of the input signal, and the selection of the useful signal occurs in a correlation way. That is, with a huge amplitude of noise at the input, the receiver will emit a very small useful signal in amplitude (during convolution, the amplitude will increase by the width of the signal base once). And when using the Walsh-Hadamard functions in channel separation and noise-resistant coding, it is almost impossible to suppress these signals !!! I don’t even want to listen to the ravings from our military PR specialists, if someone wants to argue reasonably, I'm waiting for answers.

[Galleon]

Al Popoff:
This is a wonderful replica. It’s good to think the same overseas. They would have thought that downs with soldering irons had gathered in Russia and steamed something to the state, calling it a radio-electronic system. Remain the smartest, the rest of this is only good.

You see, if you could argue with arguments, you would work for those same “military PR specialists”, creating electronic systems of a new generation, and not shake your institutional knowledge 20 years ago at the forum.
