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 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.

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.”

The important role of UAV jammers in future electronic warfare

The working frequency and signal strength of the UAV signal jammer are higher than the expected signal of the receiver. Therefore, if the jammer has sufficient power and a sufficiently wide signal spectrum, it may block all receivers in one base station. Another method is to jam the copy of the expected signal and trick the receiver into receiving the interfering signal instead of the expected signal.

The U.S. Army hopes that signal transmitters now installed on drones will dominate electronic warfare (EW) and is turning to a contracted transmitter that is poorly understood and not strictly regulated. According to four U.S. officials, the Russian military has been using GPS to intercept drone jammers to interfere with some U.S. military drones operating in the Syrian sky, which has seriously affected U.S. military operations.

A few weeks ago, the Russians began to interfere with some smaller American drones. Officials explained that the Russian military was worried that the US military would retaliate for the retaliation and began to block the GPS systems of drones operating in the area.

However, in another case, the wireless link is particularly vulnerable and is deliberately blocked. Here, someone deliberately uses a particularly effective attack against a specific link or link family to prevent the link’s communication capabilities. For malicious purposes, such as profit-making purposes, or to gain military advantage during wartime, you can try to block. The GPS agency of the US government is convinced that commercial aircraft “maintain alternative navigation methods” to prevent terrorist attacks. The agency said: “The government is currently sending new GPS signals, which are more resistant to interference.”

Drone jammers are becoming more advanced in electronic warfare

The Navy sent hundreds of electronic warfare experts to Iraq to lead the harsh sound in a harmonious manner with 14 types of jammers to allow the device to send its signal and then remain silent for a few milliseconds so that other devices can transmit; In this way, Warlock Red and Warlock Green can be packaged in a combined unit.

It is believed that North Koreans own old drone jammers purchased about ten years ago, as well as their own household equipment. These military jammers were placed on the hills of Kaesong province, near the border, to reach the maximum range, Rust said.

A new generation of military jamming equipment has also been introduced, which can cover a wide frequency range and perform specific “triggered” jamming, which means that “Duke did not mistake the receiver for a modified version of its own signal, a series of built-in Interference response is aimed at deceiving very specific equipment. “With the improvement of jammers, Iraqi insurgents basically abandoned the use of FDI, and the number of deaths from FDI declined.

The reason for the use of jamming equipment, a military switch called the radio-controlled improvised explosive device electronic warfare system (CREW), attempts to intercept or intercept the signal before it reaches its intended target to prevent an explosion. A common method is barrier interference, which can eliminate a wide range of radio signals. However, it also prevented the communications used by the US military. The United States, which exposes them to greater risks.

Interference involves pumping RF into the frequency range that they have enough to control their own signals. Therefore, you need a power supply and you need to know the frequency range. Because RF decreases with the square of the distance, unless you can aim very carefully, you must be close to or have a lot of power. They don’t really release the target you need to aim for, so they need a lot of features.

The tremendous role of drone jammers in electronic warfare

The first use of countermeasures against electronic interference can be traced back to the Second World War. Radar-controlled artillery shot down many enemy aircraft. These systems use radar signals to block and track air targets and command air defense firepower. When conducting critical joint operations, the Resistance placed the drone jammers near these weapons. The image in the news film shows how the shell randomly rotates and shoots randomly due to interference.

In electronic warfare, some officials said that the equipment used was developed by the Russian army and is very advanced, even for certain encrypted signals and anti-jamming receivers. So far, this drone is a small reconnaissance aircraft, unlike the large “predator” and “reaper”, they usually operate in a combat environment and can be armed.

Since the target may be moving, local Wi-Fi broadcasting is a more direct method. Here, when transmitting a signal in a specific frequency band, a higher power level than the initial signal can overwhelm the receiver and block communication. Four U.S. officials told NBC News that Moscow was worried that the United States would block the GPS systems of some small drones in order to retaliate against attacks on the eastern Guta area occupied by the rebels.

But sources told the National Broadcasting Corporation (NBC) that it turned out that the advanced UAV jamming equipment developed by the Russian army is effective even for certain encrypted signals and anti-jamming receivers.

Drone jammer plays an important role in electronic warfare

It now appears that North Korea, determined to expel US troops from the Korean Peninsula, may have successfully hit this fatal weakness. Although the Pentagon denied the news, South Korean military reports believe that the concealed drone jammers on the North Korean hill is likely to cause an “emergency landing” of the US spy plane.

Sources say that Russian companies are also unlikely to be involved in providing Iraq with the most effective Russian equipment, such as an electronic jamming system that could damage the US air-to-air missile attack in Baghdad. However, the same source said that some Russian technicians who once worked for the Russian army may decide to go to Baghdad in their own name out of sympathy for the Iraqis.

In addition, the military has other systems that can minimize the impact of GPS signal interception on the bomb. A Boeing spokesman said that the joint direct attack ammunition combines GPS guidance kits and gravity bombs, as well as a separate inertial navigation system, which is used as the primary means of finding targets.

Remote control high-power military jammers are widely used in prisons, protection, surveillance and other fields. If you are looking for a powerful and effective office interference device, you can stop here. Just put the device in the shopping cart, if you use this kind of interference in the office, you can easily block the mobile phone signal in the office. Because it locks the entire phone, your employees will not have the right to disclose more information.
