Russia’s powerful drone jammer equipment

The U.S. Army declined to confirm whether any drones crashed due to Russian drone jamming devices. The Russian army has established a ground force dedicated to defeating enemy drones. This device is the first such device in Russia, and its electronic jamming system can theoretically cut off the radio connection between the drone and its operator.

Allegedly, the Russian-made drone jammers recently successfully shot down the drone, but this does not mean that the large military drone fleet in the United States has no defense capabilities.

The photos accompanying the Kremlin announcement show the drone jamming gun-essentially a powerful radio transmitter on a heavy truck. Russia deployed the Krasukha system in Syria with a view to forming an electronic shield against the country ’s Russia and allies. Signal jammers will disrupt the enemy’s own signals, thus preventing ground controllers from commanding the drone via satellite.

Despite the U.S. drone. The US NBC quoted US officials as saying that they are equipped with anti-jamming technology. United States They claim that Russian interrupt technology “is very advanced and effective even for certain encrypted signals and anti-jamming receivers.”

China’s uav jamming threatens the situation in the South China Sea

China has installed high-end UAV jamming equipment in the Nansha Islands, which can block communication and radar systems, which is an important step in its gradual militarization. The American who described the discovery said: “China has deployed a military intervention team at its post on Nansha Island.”

The US assessment was supported by a photo taken by commercial satellite company DigitalGlobe last month, which was published to the Wall Street Journal. It shows a suspected drone jammers system whose antenna extends to Mischief Reef, one of the seven islands in the Nansha Islands. Since 2014, China has built an artificial island on the island to move sand to rocks And on the reef, and paved with concrete.

The US Army hopes that RF jammers installed on drones will dominate future electronic warfare, and he is turning to a method of contract acquisition that is poorly understood and not strictly regulated. Although China believes that island construction is to ensure maritime safety, assist navigation, search and rescue, protect fishing and other non-military functions, wireless jammers are only used for military purposes, “U.S. Department of Defense officials said.

Russia’s powerful military drone jammers

In order for the radio station to work properly, the radio station must be close enough to the signal your team wants to interrupt. According to an independent think tank specializing in military electronic systems, at the same time, powerful military drone jammers can detect targets 93 miles away, such as advanced drone gun jammers.

This is why Russian nuisances and new “special forces” targeting drones that operate them do not necessarily pose a survival risk for U.S. drones. A former U.S. drone developer explained: “Unless you know their location and time, it seems difficult to do it.”

Signal interruption is not limited to interference. More and more reports indicate that the Russians are expanding their ability to forge system signals, targeting the wrong receiver. In June 2017, we reported the report of the US Maritime Administration. Regarding such incidents in the Black Sea in the United States, the navigation equipment of ships showed their positions in the Black Sea.

The Russian Army now has a special UAV hunter force. The first type is the ground collective, whose electronic jamming system is designed to cut off the radio connection between the UAV and its controller. However, there is not much threat to the US military. In order for these radio interference transmitters to work properly, the device must be placed very close to the target. Unless you know where they are going and when, this seems difficult to do.

UAV jammers play an important role in war

In a statement on NBC News, officials of the Ministry of Defense did not confirm whether they had lost any drones due to traffic congestion, but one official said the blockade had an operational impact on Syria ’s military operations. The European Organization for Security and Cooperation, which has been monitoring the Ukrainian conflict, also reported that the drone they used to monitor the front line has been intercepted several times.

Commanders may be more hesitant to use GPS-guided bombs or rockets, especially near friendly forces, if they are worried about getting them on the wrong target due to interference or other forms of electronic warfare. In turn, this may greatly limit the fire support options available to the US military or its allies.

The drone did not appear to be hit by a projectile or laser when it descended (although the evidence to do so would change this analysis). In addition to physical projectiles, there are three known non-dynamic methods of preventing drones: radio frequency jammer, satellite interference, and identity fraud. Due to the interference of the drone jammers, the connection between the drone and its operator will be cut off, which usually causes the drone to descend or return.

Using a drone jammer, the drone will lose its link to satellite navigation, and the drone will usually float in place, land or return home. Through identity theft, the attacker will provide new information to the drone to control its flight.

Drone jammer based on radio control frequency interruption

The terrorists used Russian drone jammers, and Russia’s advanced jamming and electronic warfare capabilities are well known. The conflict in eastern Ukraine involved the use of Russian capabilities and aid to Russian-backed separatists. The Ukrainian Armed Forces provided the US Army with a unique perspective to examine Russian capabilities.

The function of a wireless jammer is to deliberately block or interfere, essentially “blocking” the wireless signal to interrupt the communication between the sending device and the receiving device (ie, remote control and drone). Traditionally, blockades have been used to disrupt enemy communications on the battlefield. The jammer will emit noise at the same frequency, essentially overwhelming the receiver’s ability to understand the message being sent.

anti uav jammers remote control

In some countries, wireless jammers are used as sensor devices to prevent harmful radio signals from neighboring countries from being received by their citizens. Drone jamming devices are designed to interrupt signals in the 2.4GHz and 5.8GHz range, which will interrupt most home WiFi systems, Bluetooth devices and drones operating at 2.4GHz.

Over the past year, there have been many anti-drone technologies that use lasers based on “radio-controlled frequency interruption” or “UAS directed energy countermeasures.” The latter method is being developed and promoted by the Applied Science and Technology Laboratory. The more popular drone gun jammer is one of its inventions.

Drone jammers block radio frequency and signals from satellites

What is a drone jammer gun? The device has certain configurations, is a fully integrated rifle-type countermeasure, and can be used with a variety of UAV models. Although it looks like the most powerful electron gun you have ever seen, it is actually a high-power military jammer device capable of interrupting multiple frequency bands simultaneously.

By blocking radio frequency and signals from positioning satellites, the device interrupted the control functions of commercial drones. Britain is ready for a robot-to-robot war. A new type of anti-drone weapon system developed by Blighter Surveillance Systems called “Anti-Drone Defense System” is a combination of radar, camera and jamming system, all integrated into the device.

This is how it works. First, radar recognizes and tracks flying drones. Then, once the drone is within range of the jammer, the drone jammers device attacks it: three antennas send radio frequency signals to the target drone, trying to isolate it from the original controller. Within seconds, the stuck drone stopped in midair and then fell to the ground.

Among the challenges he faced while working at the signal station, Eng Hosni said: “I have to get all parts from East Asian countries. Gather enough information on how to operate this equipment. I travel to France, Spain, Italy, South Korea and Malaysia To understand how the system works. “He said that the drone jammer has been successfully tested on a drone about 300m high in remote areas. “In the future, I plan to manufacture jammers with screens.”

Anti-drones jammers for military countermeasures of various countries

The US Army has been evaluating various anti-UAV measures for several years, mainly including blocking UAV signals, as well as radar detection and conventional counterattacks that are often used on aircraft.

Jeffrey Cavada, deputy director of the Information Warfare Integration Department at Marine Corps Headquarters, said: “If you only remain stationary on a certain part of the spectrum, you will definitely be attacked and stuck.” “However, if you can manipulate in the spectrum and can feel and operate towards the clean part of the spectrum, that is all the purpose we are doing.”

Google conducted a quick search and found that several companies claimed that the equipment sold would block the drone control signal, which may cause the quadcopter that the manufacturer did not want to crash or return to its original point. Do you have a drone and want to play it? This technology uses wifi interference to launch, which can interfere with the connection between the drone and the controller. This can be very effective when removing drones that use Wi-Fi as a communication method.

Long-distance jamming uses drone jammers interruption technology to block drones in the air to help establish the safety of military installations or civilian colonies. The weapon operates on standard GPS and ISM radio bands (2.4Ghz 5.8Ghz Wi-Fi) and can interfere with commercial drone signals. The gun can operate in a wide frequency range, so that it can detect and shoot down the drone from a long distance.

Drone jammers technology has become the most popular technology

In all the news reports on the use of infamous civilian drones and near-air accidents, it is not surprising that another new technology made headlines: “Anti-drones equipment” or “anti-drones” .

The drone jammers gun has successfully passed the French military’s DREP test, which measures the electromagnetic radiation level of human users. In fact, as Bloomberg pointed out, this is not a weapon, but a drone jam: to be precise, it is an HP 47 Counter drone blocker. It does not shoot the aircraft from the air: instead, it prevents the operator from controlling it remotely, lets it float in the air, and prevents the image or video from being sent back to its owner.

wireless drone blocker

It works by interfering with the UAV’s wifi signal, causing the reception band to be blocked. The UK is always ready to use advanced UAV jamming technology in large public events and sporting events to detect, track and change the control of any UAV where terrorists fly long-range as air weapons.

The US government has spent $ 17 billion to purchase 50,000 jammers, but at the beginning of the war, the crossfire game between signal interceptors and improvised explosive devices was far behind. They are too slow to adapt well and can only provide protection within a few yards. Two jammers lock and cancel each other every moment.

Drone jammer has become a necessary technology in prisons.

A New South Wales Correctional Services spokesperson said that the Australian Communications and Media Authority (ACMA) recently approved a two-year test of drone jamming equipment at Goulburn Prison. The U.S. Army hopes that the signal transmitters currently installed on drones will dominate in future electronic warfare, and he is turning to a contractual acquisition method that is poorly understood and poorly regulated.

Lithgow’s signal jammer equipment uses dozens of antennas installed inside the center to transmit very low-power signals, thus preventing any mobile phone in the prison from connecting to a networked mobile phone tower. A spokesman for the Ministry of Foreign Affairs of Vietnam said on Tuesday that China installed military equipment for drone detonators at the Trong Sa post in the Nansha Islands of the South China Sea.

In terms of effective isotropic radiated power, advanced modulation and capacity, ALQ-99 can be traced back to 50 years ago, and has reached its functional limit, especially for modern threats. “The reason why we buy the next-generation drone jammers is that this threat will become increasingly serious because its initial growth will reach its initial operational capacity around 2021. This threat lies in the electromagnetic spectrum. The next war will be on electromagnetic waves On the spectrum.

Those modified “cargo groups” are sent to the US military by email. The United States rearranged blockers nationwide. This cumbersome procedure took several weeks before the new frequency was recorded in the spreadsheet. Even if hundreds of new sources of interference arrive in Iraq every month, this requires more detailed analysis and other reprogramming . Senior defense officials recalled: “This is a disaster.”

Drone jammers become more important in electronic warfare

The US strategy is defined in four words: “put them back online”. By neutralizing the radio-controlled bomb, the signal interceptor will force the rebel bomber to use more basic triggers, such as command cables. In theory, these triggers will be easier to detect and bring the detonator closer to the bomb, where the US military can control the bomb or kill it.

Drone jammers usually cause the drone to land vertically or return to its starting point, which is the default action of most unmanned uavs that have lost communication capabilities. As more and more disruptors flooded into the war zone, it became more and more chaotic. For many months, the experience of electronic warfare between army and naval units has been clearly insufficient. Admiral Archie Messi, commander of the Naval Surface Warfare Center, said: “We put all these jammers there, people don’t know how to use them.”

Electronic “self-killing” has intensified, and more instances of drone interference have disrupted alliance radios, and even interfered with the radio links of drones. More troops shut down their CREW system without risking destroying their radio equipment. Rumors spread that the jammer actually detonated the explosive device.

The United States has the world’s only tactical jamming fighter, but their AN / ALQ-99 pods, which rely on simulation technology, are difficult to maintain and have reliability issues. All-digital technology and modern transmit / receive electronic equipment have made breakthroughs in capacity and availability, making the US Army possible. The United States is making next-generation jammer replacements for the pods on his tactical attack aircraft.
