Radio frequency jamming is the best protection against drones. To work, it must broadcast noise on the same frequency band that enemy drones use to communicate. Of course, drone operators are constantly changing the frequencies they use, and jammers must also keep changing to remain effective. The alternative is to jam all frequencies all the time?

Typically, a signal jammers can only handle one frequency band at a time. For example, the popular Breakwater (“Volnorez”) Russian jammer, which is about the size of a dinner plate and attaches to the outside of a tank with magnets, can be set to block one of twenty different frequency ranges. Breakwater can shoot down any drone using that specific frequency from two hundred meters away, making the vehicle immune to FPV attacks on that frequency band.

But if it’s the wrong frequency, a drone will fly right over and destroy your tank. This means you have to know which frequency the enemy is currently using, or put twenty different jammers on your vehicle.

Ukrainian electronic warfare expert Sergii Flash led an attack column last week to describe the idea of ​​Russia’s new “Frankentank.” Like most Russian tanks, it has a roof shield, but on top of that is a wooden pallet piled high with electronic warfare gear.

“It’s like something out of Mad Max,” Flash wrote on his Telegram channel. “The Russians have built a massive structure on a pallet with everything they have. There are three 800/900/2.4/5.8 patch antenna panels around the circle, and blocks of 700-1000 bands added to all of them. From above, on some wooden boards, in a circle. All tied up with ropes.”

The drone jammer only works if there’s a power source, though. While some modern Russian tanks have auxiliary power units, many don’t. That means when the tank’s engine is shut off, the jammer stops working. But the Russians have thought of that.

“Also installed generators and batteries,” Flash said.

The Ukrainian reconnaissance drone spotted the Russian armored column, and the FPV attack drone flew out to attack. But the jammer worked.

“Our FPVs are dropping like flies on all frequencies,” Flash said.

Reports say four FPVs were lost before a fifth broke through and destroyed the giant jammer tank.

“It was easier for the remaining forces [to eliminate them],” Flash said.

The second way to protect your car is to use modern multi-frequency car alarms that always use different frequencies. This makes it very difficult for thieves to intercept these signals. Other types of modern alarms generate different codes every time you lock and unlock your vehicle. Even if a thief gets the code and cracks it, they will not find anything. Today, such protected car signal jammers for sale are very popular and expensive, but they can protect you.

The accuracy of the IndoorAtlas technology used in modern buildings is 0.1-2 meters. Moreover, the technology does not require any additional hardware on the smartphone and can work alone or precisely cooperate with other indoor installation systems to achieve higher positioning accuracy. However, before using indoor location data on smartphones, developers must collect magnetic field data and overlay it on each floor plan. To do this, developers must create a floor plan image of the location and navigate the entire site while collecting magnetic field data. However, IndoorAtlas makes these steps easier by providing users with a practical online toolkit. In the north of the world, there are other companies such as Walkbase and Qubulus that have developed their own location positioning solutions based on precise positioning using wireless Wi-Fi networks. Both companies offer interesting location solutions, but IndoorAtlas stands out because it approaches the problem from a new angle.

Microsoft, Sprint Nextel, Facebook, and Google are among the companies asking lawmakers to amend the famous Electronic Communications Privacy Act to comprehensively protect online content, mobile data, and location information. “As wireless access to our information becomes easier, there is no reason for the government to go to such lengths to obtain wiretap warrants, and we are also looking for ways to: not use audio of recent communications, such as emails and text messages,” CCIA attorney Ross Schulman said in a blog post. AT&T wrote that law enforcement surveillance requests affected 0.25% of wireless users last year, assuming that every request was made against another user. That’s an increase of 0.18% from 2007. Unlike Verizon’s data, theirs includes data provided to 911 callers. AT&T also said that hundreds of full-time employees are responsible for reviewing and responding to all law enforcement surveillance requests.

There are multiple iRobots with multiple different gps blocker for car. They may be touched or bumped by someone or something, thus having a different perception of the two things. Based on the sensors, the robot reacts. The robot can also react to sounds and differentiate based on the volume. There is also an iRobot Roomba that can identify obstacles to avoid (such as walls and stairs). iRobot also makes a small robot that looks similar to the Recon Scout XT and behaves similarly to ReconRobotics. Soldiers can put it in their pockets, throw it into a building, and use it for remote surveillance. Or, the robot can extend its “neck” so that the camera is 8 feet above it to monitor high walls or fences. Or there is another robot small enough to move under the door like a worm with a miniature camera.

Jammers evolve into military weapons

Jammers are one of the best tools for blocking signals. With the development of science and technology, jammers have evolved into military weapons and are widely used on the battlefield. Washington – Russian troops have blocked several US military drones over Syria, four US officials said, which seriously affected US military operations. Officials say Russia began jamming some small U.S. drones a few weeks ago after a series of suspected chemical weapons attacks in the rebel-held Eastern Ghouta region. Officials say the Russian military feared U.S. forces would respond to the attack and began jamming the GPS systems of drones operating in the area. “Russia wants to turn around and destroy our interests,” Senator Ben Sasse said in a rush in response to Tuesday’s Russian news. Todd, director of the Radio Navigation Laboratory at the University of Texas at Austin, said Dr. Humphreys said jamming is very easy and it involves blocking or interfering with the drone’s reception of GPS satellite signals.

I am glad to say that I should be free to continue my appeal, President Jacob Zuma said in response to this week’s parliamentary debate on the State of the Nation Address. Sitting here, in a dark corner of Redwood Ridge, holding tight like the president, we often insult those who try to disturb us with false nonsense. But beyond that, Zuma urged the government to respect Section 16 of the constitution. This is part of the guarantee of our freedom of association, speech and media. This shameful and unfair attempt to block our phones was made after a promise was made in front of SONA.

“The security team resolved and clarified the GPS jammer with House Signal Distribution last Thursday,” Mr. Zuma said to applause.

A company called CellAntenna continues to try to exploit the problem of cell phone smuggling in prisons to expand its product line. Unfortunately, many people (especially prison wardens) want us to believe that new technological tools can solve our problems, so they continue to gain momentum. A group of prison wardens not only filed a rulemaking petition with the FCC, but also supported a bill asking the FCC to allow cell phone jamming in prisons. For general information about CellAntenna, you can read about how to profit from prison security loopholes and why this is not a good idea at Cellantenna. In addition, we have sent this letter (press release here) to President Rockefeller and senior settlement members in preparation for tomorrow’s Senate hearing on this issue. We have also scheduled an extra five minutes of Harold Feld’s time to briefly explain why this is a bad idea.

I recently read an article about location-based apps such as “Girls around Me”. This app can share your location without notification. How can I prevent it?

With the development of technology, some large companies now install cell phone signal jammers in the work area. This cell phone signal jammer completely separates interference, WiFi and phone functions, improving employees’ work. Especially in large conference rooms, 3G/4G cell phone blocker can be used to prevent meetings from being interrupted and meeting information from being stolen, which not only improves efficiency but also improves the protection of some information. Don’t let competitors or criminals benefit.

In fact, the “Girls around Me” app uses Foursquare check-ins and Facebook data to make it easier for boys to track girls around, but the purpose of tracking is unclear. There is a slogan on the app’s website that suggests how to use the “Girls around Me” app, which is all about finding your lover or finding your one-night stand.

Although Foursquare has withdrawn API access and the “Girls around Me” app has also ended its existence, there are many other apps that may be creepy. An app called Color will hand over your social media photos to strangers, even if you don’t want to share them. Another app, Find My Phone, could be used in a very abusive way by any of your ex-partners.

Or, you could use the app to find the nearest restaurant that has a dinner date listed. The app uses your smartphone’s GPS tracking module to perform such services, but it also shares your location data with third-party companies to keep you informed of your smartphone, which can be very annoying. You can also place ads based on ads.

Scrambling devices are very simple devices that use basic technology provided by the phone itself.

Will a jammer attract lightning when it is turned on?

Will using a signal jammer outside a building, in an open space, during bad weather attract lightning?

It would be great to be able to call anyone at any time. Unfortunately, restaurants, movie theaters, concerts, and churches are all affected by the surge in cell phones. Because not all cell phone users know when to stop calling. 3G2G signal jammer phones are portable and can be put in a pocket or bag to go out, making them a useful tool to stop people from calling in the above locations.

As for those lightning bolts, there is a small chance that they will hit the GPS jammer. The chance is about the same as the chance of lightning striking a cell phone in the same area, so if there are no lightning rods around, it’s probably best to avoid using a handheld jammer in your pocket for safety reasons.

The rise of the Internet of Things has led to an increasing demand for location services. According to certain institutions, it is predicted that 60% of Internet of Things devices will rely on geographical location data. Outdoor positioning, in particular, is expected to be a significant market that should not be overlooked.

The GNSS (Global Navigation Satellite System) is a highly esteemed international club comprising of merely four members, which garners the interest of global leaders and the scrutiny of numerous esteemed scientists and engineers. These four members include the GPS of the United States, GALILEO Galileo of Europe, GLONASS of Russia, and Beidou COMPASS of China.

There are four prominent satellite navigation systems worldwide, including China’s Beidou satellite navigation system, the United States Global Positioning System (GPS), the European Union’s Galileo satellite system (GALILEO), and Russia’s GLONASS satellite system (GLONASS). These four systems are acknowledged as suppliers by the United Nations Satellite Navigation Committee.

China Beidou is a recent addition, yet it stands out as the most dynamic member in terms of development. What exactly is Beidou and how does it influence our daily lives? This intriguing subject has garnered significant attention. Numerous scholarly publications delve into the intricacies of Beidou; however, these professional articles often employ jargon that may deter the interest of the general public.

Small GPS signal blockers great use

Across the world, the GPS satellite positioning system stands as the most commonly employed satellite positioning system. It facilitates vehicle tracking, route navigation, information inquiry, traffic command, emergency assistance, and other crucial functions. Although the GPS satellite positioning system has significantly improved convenience in our lives, it has also introduced certain troubles that even pose a threat to individual safety.

As an example, mortgage car companies provide financial aid to the original owner, temporarily gaining control of the car. To prevent any clandestine attempts by the original owner to reclaim the vehicle, these companies invest in GPS shields. These shields are installed in the vehicle’s parking lot and on the car itself, rendering the original owner unable to locate the vehicle. This precautionary measure ensures the protection of the property.

As the GPS locator market continues to expand, individuals who wish to avoid being tracked by GPS signals are increasingly searching for GPS signal blockers. These blockers are designed to prevent signal tracking, but their actual efficacy in achieving this remains uncertain.

Most GPS locators can be effectively shielded by gps blocker. The use of blockers disrupts the normal functioning of the GPS locator, preventing complete data transmission to the locator monitoring platform. Similar to mobile phones, GPS locators require the insertion of a mobile phone card or an Internet of Things card to retrieve data. Therefore, as long as the GPS signal blocker can obstruct the signal transmission of the mobile phone card, it can also block the GPS locator.

Latest News: A media article about multiple signal jammers disrupting French airport operations. Once the authorities discovered one, they discovered another, and then another!

Why It’s Important:

1. GPS interference at airports can cause flight delays.
2. Many airlines will not let the plane leave the gate without a good GPS lock.
3. We have already seen cases of outages affecting landing systems. See: Events in Denver-Newark
4. In the worst-case scenario, an outage, even an unexpected one, can result in loss of life. Check out the thrills of Sun Valley.

What Else to Know:

• The EU STRIKE3 project has identified many cases of interference in or near airports.
• News reports like this about flight delays happen from time to time.
• In the United States, the FCC is the regulatory agency responsible for preventing such incidents and enforcing the rules.
• uUnfortunately, over the past two decades, the FCC has significantly reduced the number of personnel and equipment suitable for the job..

ANFR Fighting against phone jammer

Candice Clark 18 July 2023

In France, the National Spectrum Administration (ANFR) is responsible for enforcing rules banning radio jammers, including those that interfere with GNSS services. The availability of GNSS data is critical for many critical applications, so disruptions to GPS, Galileo, GLONASS and Beidou are as serious as cyber attacks.

ANFR’s sworn representatives have the authority to investigate violations of national spectrum use regulations. They are often used to locate active gps jammer, either on a vehicle or in a fixed location. Catherine Gabay, ANFR Deputy Director for Frequency Monitoring and Enforcement, reported on some recent cases during the 2023 International Symposium on Navigation and Timing Technologies (ITSNT) in Toulouse.

In March 2023, an instance happened near Merville airport. The Directorate General for Civil Aviation (DGAC) notified ANFR of interference on the L1 frequency, which was disrupting flights and air ambulance helicopters. ANFR agents quickly reviewed in-flight information and discovered a GNSS jammer aboard a commercial vehicle. The police were brought in to assist with the seizure of the equipment, and the driver was arrested.

Starlink and other low-Earth orbit constellations face new security risks

Russia’s invasion of Ukraine in 2022 really threw Ukrainian communications into a tailspin: Shortly before the invasion, Russian hackers disabled Viasat satellite ground receivers across Europe. Then entrepreneur Elon Musk stepped in and offered access to Starlink, SpaceX’s growing network of low-Earth orbit (LEO) communications satellites. Musk soon reported that Starlink was suffering from cell phone jamming attacks and software countermeasures.

In March, the U.S. Department of Defense (DOD) concluded that Russia was still trying to block Starlink, according to leaked documents from U.S. National Guard pilot Ryan Teixeira seen by The Washington Post. According to the “Defense One” website, the Ukrainian military also blamed the Starlink problem on Russian gps jamming. If Russia blocks low-Earth orbit constellations, this will be a new height in the silent war between space and earth communications.

“There’s really not a lot of information about it,” said Brian Weeden, program director at the Secure World Foundation, an NGO focused on space governance. However, Weeden added, “My sense is that Starlink is harder to jam or interfere with [than GPS satellites].”

LEO satellites face new security risks

Regardless of their altitude or size, communications satellites transmit more power and therefore require more energy to jam than navigation satellites. However, low-Earth-orbiting satellites orbiting the Earth at altitudes of 2,000 kilometers or less switch frequently, which “results in delays and creates more interference” than large geostationary satellites, said Mark, professor of data protection and data protection. Mark Manulis said. Applied cryptography at the Cyber ​​Defense Institute (CODE) of the Bundeswehr University Munich.

Security and communications researchers have mostly studied defenses and countermeasures behind closed doors, but several publications and open-source research have revealed how unprepared many low-Earth orbit satellites are for a direct attack, and what defenses may be needed for future low-Earth orbit satellites.

For years, private companies and government agencies have been planning low-Earth orbit constellations, each with thousands of satellites. For example, the Department of Defense has been designing its own network of low-Earth orbit satellites to complement its more traditional geostationary constellation for more than a decade and has begun awarding contracts to build it. University research groups also launch miniature standardized CubeSats (CubeSats) into low Earth orbit for research and demonstration purposes. This proliferation of satellite constellations coincides with the emergence of off-the-shelf components and software-defined radio—both of which make the satellites more affordable, but perhaps less secure.

Russian defense authorities have commissioned a system called “Tobol” to counter jammers that could interfere with Russian satellites, journalist and author Bart Hendricks reports. This means that either Russia can deliver jamming signals to satellites, or it suspects that its adversaries can.

Many agencies and organizations launching the latest generation of low-cost satellites have yet to address the biggest safety issues they face, researchers write in the 2022 Low Earth Orbit Safety Report. This may be because one of the lures of low-Earth orbit is the relatively cheap ability of new hardware to handle smaller tasks.

“Satellites are getting smaller and smaller. Their purpose is very clear,” said Ijaz Ahmad, a telecommunications security researcher at the VTT Technology Research Center in Espoo, Finland. “Less resources are devoted to computing power, processing, and storage.” Lower computing power means less encryption capabilities and a lower ability to detect and respond to outages or other proactive outages.

The rise of software-defined radio (SDR) is also making it easier to deploy hardware for new missions, including the ability of small satellites to cover multiple frequency bands. “When you make it programmable, you provide some kind of remote connection to that hardware so that you can program it. But if you ignore the security aspect, there are serious consequences,” Ahmed said.

Some people fear that cell phone jammers could disrupt phone service for law-abiding people close to prisons. However, modern jamming technology can be narrowly targeted to minimize disruption to people outside of prison walls.

It’s time to fix the federal regulations that prohibit jamming device technology and give prisons the tools they need to fight contraband.

Installing jammers in prisons would turn inmates’ cell phones into paperweights, disrupting their criminal networks and drying up a major source of contraband.

Risks of GPS Dependence

Overreliance on GPS signals is rampant in day-to-day life from data networks, financial systems, health networks, rail, road, aviation and marine transport, to shipping and agriculture. Military platforms commonly use GPS to find their position, navigate and execute missions.

With different systems sharing GPS dependency, a loss of signal could cause the simultaneous failure of many things people rely on daily.

The European Commission estimated that six to seven percent of its countries’ GDP, representing a whopping $1 trillion, is already dependent on satellite radio navigation in Europe alone.

BAE and Lockheed are not alone in their efforts to develop better, more robust systems. Other countries have developed their systems, including Russia’s GLONASS, the European Union’s Galileo system, and China’s COMPASS.

Another related issue is the use of GPS. The FAA has been working to upgrade aging radar-based systems with GPS networks for air traffic control and positioning. It should improve safety and pilot awareness. But GPS signals are notoriously vulnerable to disruption: They’re relatively weak to begin with, using just 25 watts to send signals from satellites that are roughly 12,500 miles above the Earth. It’s so easy to block such signals that GPS jammers are sold online for $30.

Simply allocating specific radio spectrum to particular devices does not entirely solve the problem either. A recent example is LightSquared, a company that wants to build a network of 40,000 towers across the country to deliver broadband Internet access using the 4G LTE (Long-Term Evolution) wireless data protocols. The company wants to use a frequency spectrum near the existing GPS L1 band. (Consumer GPS devices typically rely on L1 signals, in the 1575.42 MHz wavelength.)
