US federal authorities announced a new drone directive last month: Entertainment drone operators must register their aircraft. The measure will largely manage and regulate entertainment drones, and registration will help operators understand the rules and be accountable to the public, flying irresponsible uavs, and understanding the consequences of flying hazards.

Drones have more users and enthusiasts, and these newcomers ignore the rules, which requires a certain level of training and harms aircraft in national airspace. UAV jammer will send radio frequency waves to prevent the connection and maintenance of equipment within range. After the remote jammer detects the drone signal, it will force the drone to land or return.

Cell phone jammers are popularized in hospitals

In the rapidly developing information age, more and more people are using mobile phones, and there are problems with using smart phones. In the hospital, it is necessary to provide a quiet environment for the sick. In addition, when entering a room with precision medical equipment such as an examination room, it is even more necessary to turn off the mobile phone. Therefore, we will introduce a blocking device that suppresses the communication function of a smartphone in a hospital: a cell phone jammer .

The working principle of the mobile phone jammer is that it generates interference waves with the same frequency as the base station radio waves received by the mobile phone, intentionally blocks the signal, suppresses demodulation on the terminal side, and makes communication impossible. The signal shielding range of the jammer may vary depending on the distance of the mobile phone base station. When the base station is far away, the effective range is large; when the base station is close, the effective range is small; the effective range is also related to the distance and the attenuation caused by the obstacles in progress.

At present, there are also examples of introducing jammers in other public places: the device is used in test fields and concert halls. The use of mobile phone jammers has the function of making the mobile phone “stop service” only in a specific space, forcibly disabling mobile phones in the area to ensure safety. The signal interference equipment installed in the hospital will not affect the existing hospital communication system, such as PHS and telemeters and other precision instruments.

A powerful UAV military jammer interfere multiple frequency bands

Adjustable desktop remote control signal suppressor, six antennas, powerful UAV, WiFi and GPS signals. With the help of a high-quality cooling system, the four wireless military jammer can easily operate 24 hours a day, 7 days a week. The device can be installed in the living room, on the desk, or even in the car because it has a rechargeable charger. Therefore, GPS remote control signal blockers can help track and interfere with free Wi-Fi and drones.

Avoid interference with radio waves emitted by cars, because GPS devices can establish connections with GPS devices in areas covered and maintained. This is why we cannot create new connections and maintain previous connections. The maximum distance is 120 meters. The remote control signal blocker can protect us from the interference of the GPS receiver, or if you want to track our staff, we cannot get the exact location.

The automatic remote control of the frequency suppressor also helps to get rid of the danger and boredom of the four drones. It has strong interference ability to CDMA GSM 3G 4G LTE 4G LTE 4G WIMAX GPS VHF UHF 315MHz LOJACK and other signals. Wireless Wi-Fi, drones and helicopter legs can be used in conjunction with radio waves and GPS signals. Signal interference can emit RF waves, which can break the connection. When the drone signal from the remote control signal is stuck, it will fly back to the previously given orbit, circling in the air to land or return.

Drone jammers are one main threats in the United States

Russian troops are actively trying to prevent US military aircraft from flying over Syria, interfering with the signals emitted by the Global Positioning System (GPS), thereby interfering with flight operations. Drone jammers are “seriously affecting” U.S. drone operations, but it is unclear how serious the Russian intervention is.

NBC News quoted four sources inside the Pentagon as reporting that the transmission of GPS signals began a few weeks ago. It began shortly after the chemical attack by the Syrian regime in the anti-government-controlled Guta area. According to reports, Russian troops are worried that the US military will use chemical weapons and drones to retaliate to prevent US forces from gathering intelligence.

Russia ’s use of UAV jamming without full-scale warfare will reduce its effectiveness in real warfare, because the US and Allied forces will study these signals and find ways to overcome these jamming systems. The US Army is already looking for field weapons that do not rely on GPS for millimeter accuracy. In the long run, providing military support to a regime that spends its own people may eventually hurt Russia militarily, not to mention politically.

Drone jammers technology is growing.

Cook said: “The UAV jammer was created to provide a more realistic local interference environment in which aircraft platforms and drones can evaluate their performance when the GPS signal drops.” “United States These environments are provided in other regions, and at the same time, by enabling it to directly enter the program locally and saving the cost of customers, it is not necessary to deal with the implementation of logistics costs in these places. ”

Since the beginning of the technology, it has been known that GPS can easily prevent phishing vulnerabilities. Although reports on threats faced by adversaries implementing GPS signal jamming technology are mainly concentrated in Russia, it is one of many countries that develop drone jamming and anti-spoofing technology.

According to reports, China equipped military vehicles with military GPS jammers in 2007, and North Korea has reportedly intercepted GPS signals from South Korean aircraft many times since 2010. Drone jammers work by sending their own signal on the same frequency as WiFi, which is a noisy signal, preventing it from receiving or transmitting useful information in the form of sound bursts or continuous waves.

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.
