Deploying Russian Krasukha-4 electronic warfare kit at Latakia Airport

The Syrian crisis provides Russians with the opportunity to showcase military equipment on an unprecedented scale. It has also deployed the most modern Krasukha-4 jammer system at Latakia Airport in Syria, which is a base for the Russian Air Force to combat Syrian rebels. It can be said that the use of this advanced equipment is not to defeat the Syrian rebels, but to demonstrate its niche capabilities in Russia’s world leading field. Krasuka-4 plays a role at the forefront of technology. It is a mobile ground based signal blocker that can interfere with the surveillance radar, AWACS radar, surveillance radar, and gps jamming/guidance system on LEO military satellites such as the Lacrosse/Oynx series in the United States. In fact, it can create a 300 kilometer invisible dome where friendly forces can operate without punishment. Some people attribute the success of the Russian Air Force in Syria to this equipment, including the fact that it effectively interferes with NATO surveillance.

 

For laymen, jammers are synonymous with electronic warfare. It is undoubtedly the most prominent component of electronic warfare. Modern jammers are very different from their cousins who have been around for ten years. Krasukha-4 or Türkiye KORAL ground jammer and other equipment can produce very high power output in broadband, with an effective distance of 300 km; Compared to the previous generation of gsm signal jammer with limited range and effectiveness in broadband interference mode, there has been a significant leap forward. Some reports also indicate that Russian communication suppression stations such as Murmansk BN can interfere with approximately 20 point frequencies within a range of up to 5000 kilometers. To achieve these high ranges, the jammer is no longer limited to line of sight mode and even uses reflected signals from the ionosphere. These high-power jammers based on high mobility trucks with built-in generators have shooting and rapid movement capabilities. This mobility was feasible in early low-power independent jammers. Future jammers may be consumables (including air drops) and installed on unmanned ground vehicles.

 

Due to miniaturization and better electromagnetic interference management, electronic warfare equipment is gradually shifting from ground platforms to airborne platforms, especially those that handle electronic support (ES) functions such as interception and surveillance. Due to its inherent advantages, more and more electronic warfare equipment is now based on aircraft and drones. Although airborne systems are limited by size and power output, they have advantages in range and range. The interference pods used on specialized electronic warfare aircraft are usually more powerful than those installed on other types of aircraft. The fifth generation aircraft such as the US F-35 can use almost ten times the power output of traditional fighter jets, including specialized electronic warfare aircraft, for long-range and close range interference. The report indicates that this truly multi-purpose aircraft operating in a high threat AD environment will be more effective than a single mission electronic attack on traditional aircraft. The pairing of existing drone platforms and interference pods (such as the MQ-9 Death and Northrop Grumman interference pods) brings a new dimension that allows for the use of ground and aviation assets in a comprehensive manner for spectrum warfare. When certain functions of electronic warfare aircraft are undertaken by powerful multi-purpose drone platforms, there may be a gradual shift in the future.

 

The term “spectrum warfare” is used to refer to the hybrid of electronic warfare and optical warfare, while networked electronic warfare systems are also present in the mainstream military field. Spectrum warfare seeks to combine electronic warfare technologies such as electronic jammers, interception, radar, electronic deception, and deception with optoelectronic technologies such as infrared sensors, multispectral and hyperspectral sensors, visible light sensors, and laser technology. Developing integrated programs and devices is a trend, so that enemies can become targets throughout the entire spectrum range, including optics. The fusion of cyber warfare and electronic warfare is a natural process. Electronic warfare is a rougher and closer tool, while cyber warfare is more targeted and specifically targeted at selected computer systems, networks, and applications. Interestingly, the US Army updated its field manual and released FM 3-12 on “Network and Electronic Warfare Operations” in April 2017. The future electronic warfare system will have network attack and defense capabilities, and will operate the Theater of War (TBA) at the tactical forefront, which is completely different from the strategic level of current network warfare. Such devices will have the ability to inject network malware into opponents’ networks in the air, including air gaps and offline systems.

 

Bridging the Military Civilian Gap

Traditionally, electronic warfare was limited to the military field and was a niche technology. However, the development of electronic warfare systems follows the trajectory of communication systems. The establishment and rapid adaptation of global universal standards and protocols have provided impetus for the development of communication technologies such as microwave, radio, WiFi, and cellular services. Due to their ease of procurement and integration, a significant portion of military communication also adopts these standards and protocols. A similar trend has also emerged in the field of electronic warfare, making it easy to purchase ready-made jammers or direction finding systems at relatively low prices. This has led to a surge in the use of electronic warfare systems, such as jammers for purely non military roles or at best law enforcement roles. The hardware manufacturing of advanced electronic warfare systems may exhibit a similar trend, with components, design, and manufacturing adopting a dual purpose approach, especially with a large number of required equipment (improvised explosive device jammers, mobile phone blocker, mobile phone interceptors, and direction finders) being used for counter-terrorism operations and homeland security. This mode always has its own security issues, which will be solved at the application layer and using unique software driven protocols and encryption.

Do hospitals use cell phone jammer?

Do you know where mobile phone jammers are used now? Of course, they are also widely used in places where mobile phones cannot be used and quietness is required, such as hospitals, theaters, conference halls and many other places.

GPS jammer is an electronic device that can emit electromagnetic waves with the same frequency as the Global Positioning System (GPS) signal, thereby interfering or disrupting the normal operation of the GPS receiver. The use of GPS jammers can have the following effects:

Stop GPS positioning: Using a GPS gsm jammer will make the GPS receiver unable to receive satellite signals, making it impossible to locate.

Navigation failure: The GPS jammer will disrupt the GPS signal, so the navigation system cannot function properly. This may lead to incorrect route instructions or cause the vehicle to lose its direction.

Safety issue: Using GPS jammers may cause safety issues. For example, emergency services and rescue vehicles may not be able to reach their destination using GPS navigation systems, thereby delaying rescue operations.

 

Illegal behavior: In many countries and regions, using GPS jammers is illegal as it may interfere with the normal operation of other people’s GPS receivers, and may even lead to traffic accidents or other emergency situations.

 

Therefore, the use of GPS jammers is not recommended or encouraged unless permitted by specific laws or specific application scenarios.

Each country has its own regulations and policies regarding frequency and operating company information. Before understanding this information, you need to first identify the countries or regions that interest you. Generally speaking, each country has an organization similar to the Telecommunications Administration, which is responsible for managing the country’s radio spectrum resources. You can inquire about frequency and operating company information from these organizations.

The following are some world-famous radio spectrum management organizations for reference:

1. International Telecommunication Union (ITU): ITU is a United Nations agency responsible for coordinating international telecommunications standards and spectrum allocation. You can obtain global frequency and operating company information through ITU’s website.
2. European Telecommunications Standardization Organization (ETSI): ETSI is an organization responsible for European telecommunications standards and spectrum management. You can check the frequency and operating company information in the European region on the ETSI website.
3. Federal Communications Commission (FCC): The FCC is the federal government of the United States agency responsible for managing radio spectrum and communications. You can check the frequency and operating company information of the United States on the FCC website.
4. In addition to the above institutions, there are other local institutions in different countries, and you can find their relevant information through search engines. It should be noted that when querying and using frequency and operating company information, you need to comply with local laws and regulations, and avoid infringing on the privacy and rights of others.
5. Radio interference refers to the process of intentionally or unintentionally transmitting radio signals to prevent or interfere with radio communication. These interference signals can be malicious, aimed at disrupting communication, or unintentional, such as unintentional interference signals emitted by certain electronic devices.
6. Interference signals can be emitted in various ways, including broadcast interference, spectrum scanning interference, forced muting, and random noise. These signals can cause the radio receiver to receive incorrect information or be completely unable to receive any information.
7. Radio Frequency signal jammer is an electronic device that can emit interference signals to interfere with the transmission or reception of radio signals. It can be used to prevent illegal eavesdropping, prevent electronic crimes, and protect confidential information.

 

What is the working principle of a radio frequency jammer?

The principle of RF jammer operation is to emit an interfering signal, which can overlap with the original signal, making it impossible for the original signal to be correctly received or decoded. Interference signals can be electromagnetic waves of any frequency, with sufficient strength to cancel out the original signal.

 

What are the types of RF jammers?

The type of RF jammer varies depending on its frequency range and usage. Common types include:

Broadband jammer: It can interfere with all frequencies within a certain range.

Narrowband jammer: can only interfere with specific frequencies.

Continuous wave jammer: emits continuous interference signals.

Pulse jammer: emits intermittent interference signals.

• Preventing illegal eavesdropping: In business or government meetings, RF jammers can be used to prevent the use of eavesdropping devices.
• Protecting confidential information: Radio frequency jammers can prevent radio communication from being monitored, thus protecting confidential information.
• Military use: Radio frequency jammers can be used to interfere with enemy communication equipment.
• Legal enforcement: Radio frequency jammers can be used to disrupt the communication equipment of criminals.
• It should be noted that the use of RF jammers must be legal and local laws and regulations should be understood before use.

Jammer is a jammer that prevents devices from connecting to wireless networks or communication signals. While using cell phone jammer can reduce the amount of time kids spend on their phones, it’s not a smart solution.

In a world where devices are designed to be addictive, it is more difficult than ever to keep children away from TikTok, Roblox, YouTube, and more. However, according to Sleeping Computer, some screen time rules were too strict, including a father’s solution, which ultimately had serious consequences for the town of Messanges in southwestern France.

According to a report by Agence Nationale des Fr é sequences (ANFR), the French public agency responsible for managing the radio spectrum, the Internet in a small town is unavailable between 12:00 a.m. and 3:00 a.m. After investigation, a technician detected a nearby interference signal: a device that emits radio waves at the same frequency as a mobile device, thereby preventing them from connecting to a mobile phone signal tower. Confused by why the interfering device only becomes active in the early morning, ANFR police stayed up late and tracked the signal to a house in a nearby town at 1:30 am.

It was too late to confront the homeowner, but the next day, ANFR sought an answer. In the face of questioning, the homeowner admitted that after reading an online forum about how to make his teenage child leave the internet at night, he purchased a jammer online: this is a more stringent method than confiscating the device.

According to reports, his children were addicted to social networks during the pandemic.

Due to the high power level (33dB), the signal jammer interferes with the signal of the entire town’s residential area. He severely damaged all the telephones and mobile internet in the area around his home, not only depriving his children of their rights, but also depriving his neighbors, the residents of his city and neighboring cities of their rights, “wrote the English translation of the French report.

Second, the way the jammer interferes with the signal is not controllable

If you use a gps jammer to jam your child’s cell phone signal, it may interfere with the signal of other devices, such as your neighbor’s or passerby’s cell phone signal.

Instead, you can take other steps to reduce your child’s phone use, such as limiting their time, monitoring the apps they use, or talking to them about ways to use their phones safely. It is better to build trust and communicate with children so that they understand the risks and implications of their cell phone use.

At present, the control of drones mostly adopts wireless communication technology

By transmitting high-power interference signals to the target drone, the control signal is suppressed, forcing the drone to land or return on its own. The United States uses this principle. This drone interference shield is equipped with an electronic jammer inside. Once the power switch is turned on, the high-power signal jammer will emit a full band interference signal to the drone, causing it to detach from the operator’s control and unable to receive the control signal. Automatically land on the ground. Once the drone signal is disrupted, there are usually three options: falling to the ground, returning to the operator, or descending smoothly. The effective range of this rifle is 500 to 2000 meters.

 

Currently, most consumer grade drones prefer GPS navigation for flight control, while civilian GPS signals are unencrypted, leaving room for use. The main principle of GPS deception is to send false geographic coordinates to the drone’s control system, thereby controlling the navigation system and inducing the drone to fly to the wrong place. GPS signals can be generated by generators or pre recorded and replayed. Due to the fact that the GPS signal received by drones is always based on the strongest signal source, as long as the artificial GPS signal on the ground is strong enough, it can cover the real GPS signal from space, thereby deceiving drones. GPS receiving module.

At present, all countries have set up a no-fly zone in the core area, and many UAV manufacturers have set it in the built-in firmware of the UAV. In the no-fly zone, the UAV cannot take off even after reaching the no-fly zone. Automatic landing. Therefore, as long as the artificial GPS signal on the ground simulates the geographical position as the coordinates of the no-fly zone, the UAV can be forced to land by itself.

 

At present, the control signals used by drones are mostly in the conventional civilian frequency bands of 1.2GHz, 2.4GHz, 5.8GHz, etc. With the rapid development of open-source hardware such as Arduino and Raspberry Pi, as well as the popularity of Software Defined Radio (SDR) technology, ordinary enthusiasts can also use hardware purchased online and software source code obtained from forums to simulate remote controls sending control signals to drones, which can be superimposed with the signals of real remote controls to gain control of drones.

There are many predictions for the drone industry, some targeting hardware sales, some targeting the software and service market, and some targeting specific fields. Although the numbers vary, they all indicate the same phenomenon: the drone industry has grown and grown.

 

The Haryana State High Court has criticized the government for not purchasing any jammers to upgrade the prison’s signal jammer equipment in the past six years, stating that this is a prison safety issue and why it has repeatedly delayed upgrading jammers to save money. However, the Punjab government does not seem to take prison security seriously. At present, most prisons in Punjab Province are still using GSM and 3G jammers, which can no longer interfere with the current 4G and 5G mobile phone signals, which poses a great security risk to prisons.

 

The Punjab Haryana High Court severely criticized the Punjab government for delaying the installation of jammers, despite the increasing incidents of obtaining mobile phones from prison inmates. The court said that in the 5G era, the Punjab government did not install 4G jammer GSM or 5G jammers in prisons. This cannot guarantee the safety of prisons, and this responsibility should be entrusted to the central government.

 

The High Court rebuked the government, stating that this is a security issue and why it is trying to save money by renting cell phone jammer. The Punjab government does not seem to attach importance to prison security. If this is a security issue, why worry about money? This is a necessary security expenditure.

 

The court said that if the Punjab government cannot make security arrangements in the prison, please inform it and transfer the responsibility to the central government. The High Court has now ordered the Punjab Government to submit a status report and provide a specific response at the next hearing.
