In the exercises "Center-2015" used the latest means of communication received by the troops on the eve of

New models of communications were first involved in the strategic exercises "Center-2015", passes RIA News message of the press service of the Central Military District.

"New models of military communications equipment, which at the end of August by the State Defense Order entered into service with military units and units of the Central Military District (CZO), were successfully used during the Center-2015 strategic command-staff exercise," the release says.

According to the press service, “in total, about 60 units of the new military communication technology arrived at the armament of the Samara all-arms association of the Central Military District stationed in the Volga region.”

It is reported that the military used “the latest digital Redut-2US systems”, closed video conferencing kits ZVKS-M, digital radio stations of the sixth generation “Azart-P1”, the newest radio relay stations P-419Л1, satellite stations P-438 “Barrier- T "and other samples of special equipment."

“Thanks to the automatically tunable operating frequency from 100 to 1000, once a second, they ensured a steady and uninterrupted transmission of information in a complex electronic environment,” the military department said.

The news is good, still a photo of samples, and for district 60 very

for district 60 very little

Well, most likely this is a run-in. And communication equipment is supplied with kits. 60- this is possibly a set: hardware (stationary) + portable. Further more.

would photo samples

Well, you see one in the photo - R-187-P1 "Passion".

I wonder how a change in the operating frequency with a frequency of 1000 Hz can affect the stability of information transfer? Something here the author was wise ...

[Artyom]

the author of the article understands little in radio communications. A similar algorithm allows communication to be closed from interception and scanning.

[simargl]

I also understand little in radio communications, but if the algorithm allows the transmission of information with partial suppression (partial loss of information at certain frequencies), then the phrase in the article about stability is quite appropriate, isn’t it? Despite the fact that some spectrum is suppressed (constantly or suddenly), the transmission is guaranteed to be continuously carried out precisely due to the fact that there is a constant change in the operating frequency.

[krot_tank]

Not true
The interference will occur only upon the fact of the ORE frequency. That is, they revealed the PRD - we crush it.
If the operating frequency changes at a speed of 1000 hops / sec, respectively, the PCs will not be able to detect and suppress and only natural interference or random ones at the frequency will influence. Another of the main parameters is the transmission time at one frequency before the shift; the smaller it is, the better. because 1000 Hz data are approximate. In this case, the frequencies change in a random order so that the enemy's RER could not systematize the algorithm. The mode is called frequency hopping (pseudo-random tuning of the radio frequency).

[IgorV]

I didn't find something in the text "changing the operating frequency with a frequency of 1000 Hz ...", in the text: "Thanks to the automatically tuned operating frequency from 100 to 1000 times per second ...", but these are different things.

[Riv]

Yes? And in what?

All is correct. The equipment modulates the frequency at a speed of up to 1000 TIMES per second. Try to intercept a useful signal, which changes the transmission frequency from 100 to 1000 once a second according to an unknown algorithm. This is a very difficult task for radio interception.

[Riv]

You did not understand. Frequency modulation is just about changing the frequency of the carrier signal. To say that "thanks to the automatically tunable operating frequency" information is transmitted is roughly how to say: "a nuclear bomb always hits the epicenter." And from 100 to 1000 Hz - this is probably the deviation frequency. But its change within such limits will not affect either the possibility of interception or the speed of information transfer. In addition, it was about digital stations. There, the possibility of interception is not important if there is encryption.
However, I ask questions in the wrong place. :) Yes, and the article does not pretend to be a technical one, so let the hamsters have fun.

I can throw one more topic for a shit. Is "60 sets" a lot, or not enough for the district? And if it comes to that: what is this "kit" in general? What does it include?
Throw sawdust.

[krot_tank]

I put it in order:
1. Carrier frequency modulation is one thing.
1.1. At the same time, there is not only frequency modulation, but there is also amplitude, phase, and any variations of them QAM QPSK and so on.
2. HRHF is the second. Designed to hide the very fact of the PC and interception.
3. No one listens to the tactical link (value of information from 15 to 40 minutes). They simply crush the carrier or destroy the PC.
4. 100 to 1000 Hz is not a modulation, not a deviation, not a grid of frequencies, and not even a spacing of the side frequencies from the carrier, namely, about what they clumsyly said - the tuning frequency from one carrier to another!
And You came across a Dear Friend as an engineer of radio communication systems, and for me it’s like a sickle in Y. So I spend my face without.

[Riv]

And who came across the author? :)
As for the tactical link - you are mistaken. Everyone in Chechnya listened, and even carefully. However, then the stations were not like that.

[krot_tank]

Frequency modulation at a speed of 1000 times / second is a little different. ShPS signals are broadband. HRMF is also SHPS, but the physics of the process is different.

[Riv]

The nuclear bomb hit the epicenter, in short ... :)))

[Koronik]

Good news! The truth is in the photo of the lieutenant colonel, probably still the old samples.

[rotmistr60]

Now, with a smile, you can remember the r / st link of the company-battalion-regiment R-105, R-107, R-123 on armored objects. Recently showed new r / st of this link - compact, comfortable with a longer range. In communications, we used to have a noticeable lag from foreign analogues.

And junk can be saved and used as jammers and false targets

[krot_tank]

It doesn’t work, they are calculated in half a second. no sense. Only on DX for mob reserve or on DGM.

[krot_tank]

In short, the author wrote a damn without understanding.
“Thanks to the automatically tunable operating frequency from 100 to 1000 times per second, they ensured a stable and continuous transmission of information in difficult electronic environments.”

This is the frequency hopping mode "pseudo-random radio frequency tuning", one of the types of NLS signals of "broadband signals" where the width of the frequency range is greater than the level of the signal spectrum. The trick of the frequency hopping is that in a short time, according to the algorithm, a group of selected frequencies is rebuilt, the transmission of "information" at one frequency is less than 0,1 microseconds. In this case, within the signal, there is still a bit division for each frequency. That is, the enemy's RER simply does not have time to react to the output of the PRD at one frequency. Accordingly, "did not react - did not find out - did not suppress". Stealth and intelligence protection is provided. The main problem is to synchronize the PC for simultaneous RF tuning. But it can be solved. Implemented in all PCs 5, 5+, 6 generations. In the photo P-187-P1 "Passion" is personal. Frequency hopping in the region of 10000 hops / sec (I won't say for sure! But really more!). Heaped up functions like an average smartphone. Navigation, wireless data transmission, digital maps, SMS (no MMS), no selfie camera :). Well, even with 10 functions, a normal piece of iron.
The report is finished.
