A simple weapon against drones. CPM-Drone Jammer

21

Today, the number of drones in the hands of users around the world is measured in tens of millions of units. Small flying devices no longer cause much surprise among city dwellers. Drones help to shoot panoramas, are used to prepare wedding videos and time-lapses from a height, and are used in advertising photography. Moreover, in the wrong hands, even such relatively small drones can pose a danger to people. And it's good if everything is limited only to shooting girls on the beach.


In fact, even small drones can be used in combat. Recent local conflicts have shown that such devices can be used for tactical reconnaissance, while shooting down a small air reconnaissance officer from a conventional weapons almost unrealistic.

Drones are also dangerous in the hands of terrorists, as they can carry explosives or banal fragmentation grenades, radioactive materials, chemical or bacteriological weapons.

It is no coincidence that in recent years, the use of drones has been strictly prohibited at all major sports and social and political events. For example, the ban on the use of drones over sports facilities will be observed at the next Summer Olympics in Tokyo, which was supposed to take place back in 2020, but was postponed to 2021 due to the coronavirus pandemic.

Special anti-drone guns


One of the relatively simple options for countering drones was special signal jammers. On the creation of electronic and optical countermeasures for small unmanned aerial vehicles, made in mobile or portable versions, today they are working in many countries of the world, including Russia.

In our country, such developments are represented, for example, by the products of the Avtomatika company, which is part of the Rostec state corporation. The specialists of this company have created a wearable anti-drones complex called Pishchal-PRO.

Outwardly, the device resembles samples of although futuristic, but still recognizable small arms.

This is a kind of "gun of the future", which would not get lost on the set of any science fiction film. The futuristic appearance hides the completely earthy capabilities and features of the new weapon.

Pishchal-PRO is designed to suppress communication channels, control and navigation of drones. At the same time, people without special training can also use this weapon. It can always be applied in real time, successfully neutralizing small quadcopters and enemy tactical reconnaissance means.

A simple weapon against drones. CPM-Drone Jammer

Similar developments exist today in many countries of the world.

In Italy, CPM Elettronica is working on the creation of such systems, not only mobile or portable, but also stationary, capable of fighting large drones.

One of the developments of this company is the CPM-Drone Jammer anti-drone gun, which received the DJI 120 4B manufacturer index. This anti-drone gun can be used by the military, special services, security forces, as well as civil organizations and companies to prevent access to certain objects or territories.

The devices developed by CPM Elettronica, as well as the products of the Russian company Avtomatika, are able to protect certain areas from unwanted intrusion by drones or small tactical UAVs using radio signal jamming technologies.

Interest in the creation of such countermeasures is due to obvious factors. First, the market for civilian drones, as well as for military products, has grown exponentially in recent years. Secondly, drones have become too easy to fly.

Today even a schoolchild can cope with this task, and the emergence and improvement of autopilot systems based on GPS or other positioning systems makes it possible to plan missions and flight tasks for such devices. This poses a potential hazard and threat to densely populated areas of cities or important areas, industrial facilities and infrastructure.

Moreover, the threat is not always terrorist. The uncontrolled flights of small drones can pose a threat to airport operations and passenger safety, interfere with the work of rescuers and rescue equipment, and carry out illegal surveillance and surveillance.

In addition, drones are popular with criminals who use them to deliver contraband across borders or prohibited goods to prisons. All this required the industry to develop adequate and simple countermeasures, one of which was anti-drone guns.

CPM-Drone Jammer DJI 120 4B


Developed by the Italian company CPM Elettronica, the anti-drone gun, designated CPM-Drone Jammer DJI 120 4B, or simply CPM-Drone Jammer, is already in use by the Italian military.

The device is known to be in service with the Italian Air Force, in particular the 16th Ground Defense Regiment. aviation bases. For air bases, the task of detecting and neutralizing enemy drones (even the smallest ones) is quite acute. Such devices fly at low altitude and are small in size; it is quite difficult to shoot them down with small arms or automatic cannons.

The danger of small drones and drones, including homemade ones, is confirmed by the experience of the Russian air base Khmeimim operating in Syria. According to the Russian Ministry of Defense, over a hundred different militant drones were shot down over the base over the years. At the same time, for this, not only the air defense forces of the base were used, but also the available means of electronic warfare - electronic warfare.


CPM-Drone Jammer

Developed by Italian engineers from CPM Elettronica, the anti-drone system is a compact and transportable system.

The way the CPM-Drone Jammer works is to suppress radio signals that not only control the flight of the unmanned vehicle, but also sent from its board (data from video and photographs, if the device is conducting reconnaissance). At the same time, the weapon does not directly interfere with the work of the drone's mechanics, the engines and propellers are still working, but the device itself hangs in the place where it was overtaken by the effect of the radio signal jammer.

In addition, the device is capable of disrupting GPS operation. Generating electromagnetic noise at the radio frequencies the drone operates at while jamming the GPS signal often causes the drone to make a normal landing in place while performing a vertical descent. Thus, the interception of the device is carried out, which will be available for further study and investigation.

The compact and transportable system, made of impact-resistant CFRP, includes four silencer circuits that are able to effectively interrupt the most common communication signals between drones and operators / GPS, avoiding drones hitting their targets or blocking their actions over unmanned zones.

The CPM-Drone Jammer works with four GAN Technology Power Amplifier Jamming Modules (30W each) in the 20 to 6000 MHz frequency range.

The anti-drone gun has directional antennas with high signal gain. According to the developers, one set of four devices will be enough to effectively intercept about 30 drones.

At the same time, the declared effective interception range of drones is 700 meters. The total length of the shotgun with antennas is approximately 900 mm. The weight of the entire system, including battery, backup battery and antennas, is 17 kg.


The anti-drone gun developed by the Italians is powered by lithium batteries type BB2590, the package includes two batteries, as well as a charger for them.

In standby mode, the gun can work up to 20 hours, in active mode at full power - 1 hour. At the same time, the range of application specified by the developer is designed for warm and hot climates.

The device operates in the temperature range from 0 to +55 degrees Celsius.

In winter, in cold weather, it will not work.

    Well ... no matter how modern drones "freeze in place" when the control signal is lost, but return along the "recorded path" or according to the algorithm introduced to the launch point or somewhere else. Modern drones, even small ones, have protection against jammers - switching to other frequencies or moving along reference points pre-selected on the map loaded into the drone's memory. Such "jamming guns" will work only on very simple "commercial use" drones

      Disrupting remote control of the drone is also good. at least he will behave predictably.

          In standby mode, the gun can work up to 20 hours, in active mode at full power - 1 hour. Wherein the application range specified by the developer is designed for warm and hot climates.

          The device operates in the temperature range from 0 to +55 degrees Celsius.

          In winter, in cold weather, it will not work.


          Obviously, the conclusion about the impossibility of using this tool in cold weather was made by the author of the publication on the basis of the characteristics declared by the developers, which were not designed for use in a cold climate.


          But on the other hand, what prevents to place an additional battery for heating the device in a backpack with a "system unit" (photo)? It will not take up much space, and the weight will not increase at all significantly.

            I thought what the assistant operator was doing: a) keeps it so that the recoil does not dump; b) controls the operator, or maybe interest in the sirloin.

              If not one and not the other and not the third, then maybe just rummaging through the contents of the backpack while your partner is distracted?

            It's just that there, most likely, a module without thermal stabilization of the generator - the jammer, here the radiation spectrum "walks", at below 0, most likely local developers saved on the final cost of this product :)

      drones don't "hang in place"

      hi
      I don’t understand: are mufflers capable of acting only on aircraft?
      After all, there are both ground platforms and surface ones.
      Underwater complexes are a separate topic.

      And if we assume that such a product will disable / drown out the positioning channel? Without positioning data, the drone will not be able to execute the given routing algorithm ... Also, I would venture to suggest that it is technically possible to intercept the control of the drone ...

      If the terrorists come up with an RPG 7 attachment to drones, it will be a problem.

      For the RPG-7, with its weight and dimensions, the drone should be very large.
      In the meantime, fortunately, we see that terrorist groups use only small UAVs that are not capable of carrying such a load.
      And in addition, for this kind of combat drone, the issue of aiming weapons becomes relevant, in this case - an RPG at a target, unless of course it is a kamikaze drone, which can be guided by the operator according to the data from the camera of the device.

        why large, there are also small fragmentation warheads, depending on the total mass of fragments and their number after crushing, and even cumulative, with different mass of explosives and funnel material ...

    "To prevent access to certain objects or territories" for these purposes it is better to use semi-stationary settings. They also have a larger radius of action and can work in an active mode longer. Anti-drone guns are good against single drones.
    On NTV in December, they showed the series: "Sea Devils" and there, according to the plot, terrorists are against: "Seals" launched a drone filled with explosives, and it was paralyzed from a similar gun

    This is only for simple semi-child drones that do not have protection against such devices.
    If communication is lost, the drone will simply return if the navigation signal is jammed at the same time - it will also return via inertial navigation until it leaves the jamming zone and restores control and navigation signals.
    In principle, analog video cannot be suppressed by such a device, it is necessary to influence the receiving station, not the drone.
    Interestingly, but the operator is not adversely affected by the side lobes of this gun?
    And will not drones be sent specifically to attack these gun owners? This, by the way, concerns all the active means of electronic warfare, the goal is too obvious.

    All this pampering! Hope for electronic warfare, and keep the anti-aircraft gun ready! I am a supporter of the physical destruction or coercion of airborne objects! There are "fiz.kirdyk" UAVs, new ones appear ... with "nuances", in the near future a "forager" will be observed in the development of anti-drone means! Machine-gun "gatlings", ghasts "with a caliber of 7,62 mm, 12,7 mm have prospects for development ... Rostec promised to develop a" multipurpose "small-caliber MLRS with guided and unguided eres ...; drones-interceptors with" shrapnel " missiles with a caliber of 40 mm and above, "laser" 40-mm missiles of the "Pike" type; automatic rifles of 12 gauge (for them "special cartridges" are being developed ... for example, SkyNet Mi-5), it is possible to create recoilless grape-shooters ("shotguns ") revolving type for UAVs ... For the self-defense of ground units, interceptor missiles of the MNTK type will be useful. In order to capture air objects for study, air-to-air and surface-to-air missiles equipped with special nets can be used ... perhaps, and parachutes (balloons) ... EW ... let it be ... for safety net!
