In recent years, with the development of drones, it is not uncommon for drones to fly in the dark, and the market for drone jammer is also increasing year by year. So what are the current types of drone signal jammer in China?
The drone frequency jammer system can be divided into the following three categories according to the UAV countermeasure technology:
1. Interference blocking, mainly through signal interference, sound wave interference, and other technologies
2. Direct destruction, including the use of laser weapons, the use of drones to counter drones, etc.
3. Monitoring, mainly by hijacking radio control.
Our usual countermeasures in the civilian UAV field are mainly jamming interception and detection control, while the direct damage category is mainly related to the military field and is ignored.
Interference blocking category: mainly use radio communication technology to control drones. By sending a high-power jamming signal to the target drone and suppressing the control signal, the drone can be forced to land or return on its own. The main popular products are drone anti jammers, full-band UAV countermeasure system
Detection and control categories: mainly refers to radio hijacking, GPS satellite navigation deception, and hacking technology. The main best-selling products are UAV navigation and decoy system, UAV spectrum detection system, UAV detection, observation and attack comprehensive equipment.

The risks posed by the misuse of drones have grown exponentially in recent years. The purpose of this short article is to examine the risks that one should take when using drone jammer.
The threat of drones is wide-ranging, starting with the use of drones by ISIS in combat in various countries, to reconnaissance drone flights by Iranian drones in military operations over the U.S. fleet in the Gulf, to civilian use of drones. Human-machine inadvertent infiltration. most likely) to the airport airspace.
Drone threats fall into two main operational concerns. The first is detection which can be achieved through a number of techniques, most likely through radar, passive RF detection, cameras, etc. The second, more acute, is the countermeasures. Few methods have been introduced so far, such as prayer birds, cast nets, short-range guns, hacking, and deception, but the most popular and cost-effective method of operation is to suppress RF signals from drones and controllers.
When countermeasures are raised to various security entities and airport authorities, several questions immediately arise because the main question is: "What if the drone lands on someone's head? One security guard even stated that he I'd rather have a plane crash than a drone on a child's head.
Before answering this serious dilemma, it is prudent to explore the well-known causes of the drone threat in most countries today, but few practical steps have been taken to mitigate the phenomenon. Here are a few reasons why the risk has yet to be responded to:
Missing 9/11: Every security measure taken is usually based on a tragedy in which many people lost their lives, such as 9/11 before security measures were taken. In our case, the question is we should ask ourselves 'why do we always need tragedy to deploy the required safety measures? The answer to this lies in the second argument.
Psychological factors: Even when fully aware of the danger, people rarely take preventive measures. Examples are numerous, starting with people smoking, drinking and driving, etc. Also, since 9/11 has yet to happen, security groups will go the extra mile to ask their superiors to allocate funds for this threat. One might even argue that because of their size, it's hard to detect that something so small can do a lot of damage.
Regulations: In many countries, prohibitions are illegal unless specifically permitted by state authorities.
Liability: Use of countermeasures that may affect the environment and cause harm to hold safety agencies liable for litigation.
Overall, many security agencies seem to be looking for a panacea, a 100% security solution, a countermeasure system that would allow them to control every existing drone from great distances (several kilometers), while The cost of the system will be roughly equivalent to the cost of a small luxury car (about $100,000).
So how is the risk of using countermeasures such as RF suppression calculated compared to the risks involved? The solution always lies in the perception of the threat and the technical solution. The risk of advertising falling from the sky is very real, the world counts near misses every day, and it’s only a matter of time before drones cause planes to crash. Now, while the probability of a drone crashing into a commercial flight is on the rise (more drones are being used every day), the risk of a drone crashing on someone's head is extremely low.
Let's explain why: First, most drones have a flight home feature, which means that once I suppress the controller and the drone's connection to the ground, I can leave the GPS connection unblocked, allowing the drone to fly home. controller.
This method of operation is likely to solve nearly 100% of the problem of drones floating away or falling from the sky. Second, once a specific area has been secured, a thorough analysis can determine where the drone is most likely to land safely if GPS is also suppressed. In addition, various other techniques in the method of operation of the system can be used in conjunction with the use of a drone signal jammer to disrupt the flight of the drone without causing it to fall to the ground.

Drone hacking is easier than previously thought
More than 500,000 drones are currently flying over the U.S., with more than 7 million expected by 2030. A Johns Hopkins study (completed in 2016) exposed the soft underbelly of amateur drones.
Johns Hopkins School of Engineering team leader and cybersecurity scientist Professor Lanier Watkins assigned his master's degree students to the job. The team found 3 ways to interfere with the activity of airborne drones, using just a laptop -- forcing them to land or crash.
Unfortunately, these hacking methods aren't limited to hobby drones. Many commercial drones face the same vulnerabilities - agricultural drones, police drones, commercial drones (Amazon, delivery services), aerial photography and videography drones, and more.
In the rush to produce and sell as many drones as possible, manufacturers often put safety concerns last. As such, such drones can be easily hacked and sent to spy on people, act as flying bomb carriers, and more.
3 Ways to Hack Airborne Drones
Here are 3 methods used during the Johns Hopkins study:
Hacking #1 – DOS attackThe team sent 1,000 wireless connection requests at very short intervals, overloading the drone's central processing unit and shutting it down. This is a well-known and familiar form of cyberattack known as DOS (Denial of Service), and it has been used successfully for drone jammer. When it's done using various multiple sources, it's called DDOS (Distributed Denial of Service). After the aforementioned DOS attack, the drone was forced to land immediately.
Hacker #2 – Packet AttackPackets are digital packets that are sent in a specific order over time. Overload can result when one sends a very large packet, beyond the capability of the receiver. That's exactly what happened in the second hacking attempt tested at Johns Hopkins -- this time the drone crashed).
Hacking #3 – Fake DroneThis time the team sent a persistent fake data packet directly to the drone's ground control unit. The purpose is to make the control unit think it is receiving commands from the drone itself, even though in reality it is just fake data. The team succeeded in convincing the control unit of this, thereby disconnecting the real connection to the drone. The hack made an emergency landing of the drone.
SummarizeA more advanced and sophisticated method of hacking drones is to use deliberate signal jamming (much like jamming and blocking cell phones in schools and public places). This method usually belongs to the corporate and military realms and is not available to private individuals.
Sure enough, these results are underscoring outcomes for both privacy reasons and commercial, commercial, military, and security reasons. One would speculate that military drones are more capable and immune to such cyberattacks, but that remains to be seen.
