The UAV market drives the development of jammers

In recent years, the drone market has grown rapidly, and with the large-scale development and production of manufacturers such as Daegu, Extreme Flight and Zero Control, the price of commercial drones has been accepted and experience has been gained. Use is good. The degree of widespread use is increasing.

At the same time, there are major hidden dangers to safety. However, many countries still have blank restrictions on drones, especially “Kurohi” drones. Approximately 90% of small aircraft flying in the air peep into the privacy of others, which poses a great danger to aerial surveillance and aerial safety.

The “Kurohi” accident occurred when the drone was injured. In the second half of 2016 alone, there were hundreds of accidents, such as stopping the aircraft or falling into a large-scale event. In the near future, an accident occurred on a flight in Canada, and an accident involving injuries occurred on the Ningbo Kurofi Highway. Faced with the unmanned aircraft control gap, we will take strong countermeasures to ensure air safety.

As a store specializing in various jamming devices, we sell professional UAV jammer. The facility can shield the position signals of all GNSS satellites, including GPS/GLONASS/Galileo.

portable drone signal jammers

The ISM 2.4G and ISM 5.8G frequency bands commonly used by humans and machines have the effects of forcibly shielding the drone, interrupting the graphic position and signal, and about/return/stop. .. Tokushin Tsushin voluntarily developed an unmanned aircraft jammer, which is powerful and can reach 1-5 kilometers (depending on different usage environments).

Our company can interfere with the positioning signals of GPS satellites and at the same time shield the 2.4 G and 5.8 G frequency interference that is usually used for drones. The interruption of position and signal forces the effect of approach/return/stop.

Legal notice on mobile jammers

The gsm signal jammer (JAMMER) is products capable of eliminating the cellular signal, in the range that goes from a few meters to about a kilometer, in some cases causing real inconvenience for anyone who happens to be within its range. Precisely for this reason they are products considered ILLEGAL in our country as in many others in the European community.

Response of the EU Commission to the EU Parliamentary Question E-2651/02 (Cell phone deactivation systems).

Reply from Commissioner Liikanen on behalf of the EU Commission (31 October 2002)

Research carried out by the Commission indicates that it is currently not allowed in the Member States to block the reception and transmission of GSM signals. Although France has adopted a law that prepares the ground for the use of inactivation systems, there are still no technical implementing regulations that allow the legal use of such devices (mobile phone jammer). The Commission is aware that inactivation systems are currently commercially available, in particular via the Internet.

Such products are illegal and Member States are therefore required to take measures in this regard pursuant to the provisions of Council Directive 89/336 / EEC of 3 May 1989 for the approximation of the laws of the Member States relating to electromagnetic compatibility or Directive 1999 / 5 / EC of the European Parliament and of the Council of 9 March 1999 concerning radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity, withdrawing them from the market. As the answer to Written Question P-2753/02 by Mr Caullery indicates, the Commission does not believe that inactivation is the right solution to the issue of inappropriate use of mobile phones. The Commission therefore does not intend to submit legislative proposals aimed at legalizing the use of inactivation systems.

In ITALY, those who use these products can interrupt a public service such as that of telephone transmission and therefore punishable by criminal law:

340 of the Criminal Code:
Interruption of an office or public service or a service of public need.
Anyone who, apart from the cases provided for by particular legal provisions, causes an interruption or disturbs the regularity of a public office or service or a service of public necessity, is punished with imprisonment for up to one year. The leaders, promoters or organizers are punished with imprisonment from one to five years.

617 of the Criminal Code:
Knowledge of illegal interruption or impediment of telegraphic or telephone communications or conversations.
Anyone who fraudulently becomes aware of a communication or conversation, telephone or telegraphic, between other people or in any case not directed to him, or interrupts or prevents them, is punished with imprisonment from six months to four years. Unless the fact constitutes a more serious crime, the same penalty applies to anyone who discloses, by any means of information to the public, in whole or in part, the content of the communications or conversations indicated in the first part of this article.
Crimes are punishable upon complaint by the injured party; however, the procedure is ex officio and the penalty is imprisonment from one to five years if the offense is committed to the detriment of a public official or a person in charge of a public service in the exercise or because of the functions or service, or by a public officer or a person in charge of a public service with abuse of powers or with violation of the duties inherent to the function or service, or by whoever exercises the profession of private investigator even illegally.
Article thus replaced by article 2 of l. 8/4/1974 n. 98.

617 bis:
Installation of equipment designed to intercept or prevent telegraphic or telephone communications or conversations.
Anyone who, outside the cases permitted by law, installs equipment, tools, parts of equipment or instruments in order to intercept or prevent telegraphic or telephone communications or conversations between other people is punished with imprisonment from one to four years.
The penalty is imprisonment from one to five years if the offense is committed to the detriment of a public official in the exercise or because of his functions or by a public official or a person in charge of a public service with abuse of powers or violation of duties inherent to the function or service or by whoever exercises the profession of private investigator even illegally.

Are bomb jammers dangerous or not?

In recent days, the “handheld gps jammer” topic on the car of the magistrate “Di Matteo” has returned to fashion. The topic deserves further study with experts in the sector, not with politicians ready to speak out to gain some consensus here and there.

We premise that, EVERY jammer device is NOT good for the human body, the greater the power and correspondingly more it will harm the health more. Erroneously from what was declared by Undersecretary of Defense Gioacchino Alfano: “The types of jammers (called jammers) used by the Italian military in operational theaters (including Afghanistan) are of medium and small capacity”. And again: “the systems do not harm the health of people (operators and strangers), thanks to the limited power”, is an inaccuracy resulting from lack of competence, as well as ignorance.

Camouflage handheld phone jammer

The “bomb jammers”, the real ones, not the imaginary ones, MUST necessarily have a power output such as to be able to neutralize any radio transmission within the range of action set as safety; generally speaking of 100-1,000 meters. To be able to disturb such a large area, it is necessary to have an output power ranging from 25-200W per channel; that added to all the necessary frequency cuts, you can easily get a device of 1.000W of power! Installing a device with less power means making it useless.

The military who use the “military jammer“, as indeed the various American presidents, visiting foreign lands, install them on separate special vehicles. In a nutshell, if you want to give “Di Matteo” a Bomb jammer, you should first think about providing a new car specifically for installing the device.

This is not only because continuous exposure to these waves hurts; but also because the Bomb Jammers are devices of a certain size which also require a separate power supply.

We were stunned to read these statements from an undersecretary of defense, we are surprised by the lack of competence and superficiality with which this topic was addressed.

WiFi Jammers for Wireless Security

We all love to use WiFi, it’s a faster wireless connection, and it’s convenient. But at the same time, we also have to use the wifi jammer. We could walk around the house while still keeping our cell phones and computers connected to the Internet at high quality. This could all be done wirelessly, which is great for all of us. But at the same time, we also put ourselves in wireless danger. People could hack our cell phones or our computers to steal our information, like our bank account, our password, our mailbox, our famous photos and all. This will put us in dangerous situations. We need to find a way to get away from this kind of wireless hacker. The wireless jammer could help us with that. It could emit a strong signal, much stronger than the WiFi signal, to cover and hide the WiFi signal, so that all wireless devices in a certain place could not receive the WiFi signal.

Are Cell Phone Jammers the Next Big Thing?

A Philadelphia man was caught red-handed this week for using a mobile phone jammer to prevent fellow passengers on a public transit bus from using their cell phones.

“I guess I take the law into my own hands,” he told an NBC10 reporter about the illegal jammer, “and to be honest, I’m proud of it.”

Teresa Masterson, a writer on NBC10, first encountered the jammer on her morning commute and gave NBC investigators a lead.

A jammer that blocks radio frequencies isn’t just limited to blocking people

But while today’s news and the resulting internet outrage can only be felt by a single man, the practice of jamming cell phones is widespread in both New York and Washington DC. I spoke to two such “jammers” this morning about why they bought equipment that ranged from $ 40 to over $ 10,000 on sites like jammer-welt.com. Some boast a radius of just 15 feet, while others claim they are used in military vehicles and for counter-terrorism maneuvers.

“You’re the best thing ever,” says a New Jersey-to-New York commuter who lugs around a jammer every morning on his 40-minute ride on the New Jersey Transit. He doesn’t do it for the entire trip, he says, only when a fellow passenger speaks “too loudly” or “too long”. “It fits in your pocket – they even make shady packs of cigarettes. I would guess it’s effective for a 15 foot radius, possibly more,” he says.

“When I’ve used it, it’s to turn off a loud speaker on the train that is sitting near me.” He says he bought it online from a website that imports the equipment from China, where it’s legal, and when asked, told me that he never felt guilty about keeping his passengers from talking. “No fault,” he says, “just personal high fives.”

“I always have a grace period for calls,” says another jammer who takes the MARC train to Washington DC. The journey takes about 30 minutes. “If someone says,” Okay, well, I’ll be in the office in 10 minutes, then we can discuss it. “I’m not going to bother you. But if you talk about what you did last night and what kind of curtains you are getting for the house, then yes. Silenced.”

Does he feel guilty? As if it was causing a public grievance? Not as much. “People are mad and ranting on their cell phones all the time. But I feel like it gives me some control over what I believe is becoming an increasingly reckless society.

“I’m not a threat to public safety,” he says. “I don’t put anyone in danger more than anyone else in a subway without the reception of cells being compromised.”

jammer-welt promotes the sensible and legal use of cell phone jammers and correctly protects their legitimate rights and interests.

Will Israel buy $ 50,000 worth of portable anti-drone vests?

The IDF and Israeli police are considering purchasing personal anti-drone systems at a cost of $ 50,000 each, Calcalist reported.

The vests were made by the Israeli startup SKYUP, part of the Avnon Group, and have already been sold to the US Army and NATO forces.

Enemy drones have become a growing threat and unlike in the past when they were only installed in vehicles, there is now a need for personal equipment for soldiers and police officers to protect them from the threat of drones. According to SKYLOCK, the portable systems, which weigh just 1.5 kilograms, can neutralize any drone within a kilometer.

3 bands uav blocker

The vests are equipped with a drone detector and an drone jammer. Upon notification of a UAV in their vicinity, carriers can activate the anti-drone jammer.

The vest is intended for use in situations where traditional anti-drone products normally installed in buildings or vehicles are not suitable due to the need for a mobile protection system, e.g. B. at special units of the army or guards of the president.

A quick and dirty guide to monitoring mobile phones during protests

As riots against police brutality and institutionalized racism swept across the country, many people were exposed to the full power of law enforcement weapons and surveillance for the first time. Whenever protesters, cell phones and police are in the same place, protesters should pay attention to cell phone surveillance. Usually, security practitioners or other protesters respond to this issue through suggestions provided by local law enforcement agencies using cell location simulators (also known as CSS, IMSI catchers, stingrays, earth boxes, hail, fake base stations, or crosses). However, in many cases, this suggestion is wrong, or it is due to fundamental reasons such as not knowing what the cellular base station simulator is, its function and frequency of use.

Denial of service or signal interference is an additional function of CSS. In fact, the FBI has admitted that CSS can cause signal jammer to local personnel. Unfortunately, for the same reasons, it is difficult to determine the use of CSS, and it is difficult to tell how often they interrupt service, whether intentionally or unintentionally. Signal towers that look like signal interference may also be overloaded and disconnected. If many people suddenly gather in one place, it may overload the network, which is not the purpose of the design.

How to protect yourself from cellular signals

As we mentioned in our self-defense guide for monitoring protesters, the best way to protect yourself from cellular site simulators is to put your phone in airplane mode and then turn off GPS [2], WiFi and Bluetooth, and cellular data. (Although “receive only” GPS and not lose its own location information, many apps track GPS location data, which is ultimately stored in a database that law enforcement agencies can search for later.)

We know that some IMSI capturers can also intercept content, but as far as we know, if you don’t downgrade your cellular connection to 2G, none of them can do it. If you want to protect your device from this attack, the best option is to use encrypted messages such as Signal or WhatsApp and put it in airplane mode when you find that your phone has fallen to 2G. (There are many valid reasons. Your phone may downgrade some of your connections to 2G, but it is safer than regretting.) However, an important part of the protest may be live broadcast/recording and immediate upload of police reports against protesters. Violent video. This is inconsistent with the recommendation to keep the phone off/in airplane mode. Up to you

Unfortunately, iOS and Android currently do not provide an easy way to force your phone to use 4G only, although developers can of course add it to their operating systems. If you can turn off 2G on your phone, this is a good preventive measure.

Saab is testing its new attack jammer for the Gripen!

The aircraft manufacturer Saab has carried out the first flight tests with its new, advanced jamming module Electronic Attack Jammer Pod (EAJP). The new drone jammer was tested on a JAS-39D Gripen fighter aircraft. The interfaces of the module to the aircraft hardware and software as well as to the control and monitoring of the cockpit were tested during the flight.

5.8g jammer

Saab’s new EAJP module aims to protect aircraft with sophisticated jamming functions from radar and prevent the enemy from attacking them. The first flight marks an important stage in the nacelle development program.

Saab is refining its electronic attack capabilities and the new advanced module is an important part of this development. The EAJP perfectly complements the integrated electronic attack functions of the advanced electronic on-board warfare system of the new Gripen E / F fighter from Saab. It can also be used for other types of aircraft. The nacelle is part of the Saab AREXIS family of electronic warfare systems, which includes: radar warning signal receivers (RWR), intelligence, surveillance and reconnaissance (ISR) and electronic countermeasures (ECM) that are combat aircraft compliant.

Electronic war systems are also used for self-protection by passively detecting radar systems and enemy missiles and protecting the aircraft or platform with active and passive countermeasures. Offensive electronic warfare, also known as electronic attack, involves actively sending jamming signals to disrupt the enemy’s air defense systems so that they are no longer a threat.

The EJP gondola:

The new low-band signal jammer is contained in a 4 m long and 350 kg heavy demonstration module. Wing-shaped surfaces are used to house the low frequency antennas. According to the Swedish aircraft manufacturer, currently only the US Navy Boeing EA-18G “Growler” can neutralize hostile electronic defenses. The EAJP has the ability to filter and thus protect the approach and departure of entire formations from low-frequency radar, thanks to the intelligent use of DRFM (Digital Radio Frequency Memory) encryption techniques, which generate false coherent and different targets. Saturation Techniques. The system is based on digital receivers and ultra-broadband DRFM devices, networked solid-state jammers based on gallium nitride (GaN) and interferometric direction finding systems. For advanced electronic attack application, these technologies are adapted to the low frequencies required to block modern stealth defense systems.

Intended for a wide range of aircraft:

If the EAJP is previously used in Sweden for aircraft of the Gripen C / D and E / F families, Saab will also advertise the EAJP nacelle to enable possible integration with other aircraft types. possibly including the Eurofighter. In Germany, for example, the Tornado ECR is to be replaced and the Eurofighter T3 ECR “SEAD” * (article tomorrow) is to be equipped. Other countries may need such a solution to equip their aircraft fleets. Saab expects it can deploy a NATO-compliant operational system in the next 12 months.

Set the distance due to GPS interference

From the construction of offshore wind farms and dredging ports to marine surveying and the laying of underwater cables, GPS receivers have established themselves as a critical element in many offshore and nearshore applications. Downtime in GPS tracking at sea can be dangerous and costly. GPS downtime is increasingly attributed to malfunctions.

The location of a chirp jammer in the car on Shelter Island that was used to simulate the effects of GPS interference on San Diego Bay. GPS signals are transmitted at power equivalent to that of a standard lightbulb. They are expected to travel more than 20,000 km and still be suitable for high-precision position calculations. In most cases, the signals arrive relatively intact, but can hardly be distinguished from the thermal background noise and can be ducks for any passing interferer.

Maritime applications are increasingly using high-precision positioning such as RTK and PPP, which not only use the code information modulated onto the signals, but also the phase of the signal itself. In the presence of interference, these phase-based modes suffer first.

The use of GPS signal jammer is strictly prohibited, but their effects can be assessed using a GPS simulator. Using the example of the port of San Diego, a simulator was programmed to generate the GPS signals that a receiver on a boat would see at that location. The interference of the GPS signals was mimicked by mixing the simulator signal with that of a jammer. With the jammer in the location shown in Figure 1 and the GPS receiver on a boat near the bay, the effect of interference across the bay could be extrapolated using standard models for the propagation of radio waves.

best cell phone jammers

The results in Figure 2 show that a small 10 mW chirp jammer without AIM + interference mitigation can turn off RTK positioning over several hundred meters. When AIM + is activated, the non-RTK zone in the immediate vicinity of the jammer is reduced to a few meters.

The effect of a 10 mW chirp jammer on GPS positioning in San Diego Bay with and without AIM + interference mitigation.

If you repeat the tests with a Continuous Wave Interferer (CW) of the same power, the results with AIM + are even more dramatic, as Figure 3 shows. Without AIM +, a CW interferer in the parking lot near the coast prevents RTK positioning or GPS positioning over a large part of the bay and extends several kilometers to the sea within sight of the jammer.

The effect of a 10 mW continuous jammer on GPS positioning in San Diego Bay with and without AIM + interference mitigation.

A comprehensive approach places interference issues in the foreground of the receiver design and incorporates them into every phase of signal processing. With the AsteRx4 OEM and AsteRx-U, the antenna signal is digitized immediately after filtering and automatically freed from interference using several adaptive band-stop filters.

Depending on the type of interference, the stop bandwidth is automatically set between a notch of a few kHz to 1 MHz in width. The notch filters are supplemented by an adaptive filter that can suppress more complex types of interference such as chirp jammers, frequency hopping signals from DME / TACAN devices, and powerful Inmarsat transmitters.
