GPS Jammers Can Wreak Havoc, Cover up Crime

GPS Jammers Can Wreak Havoc, Cover up Crime

Comparable in prevalence to electricity, the Global Positioning System (GPS) has evolved beyond a simple convenience for travelers. It now plays a critical role in landing airplanes, navigating ships, coordinating data on communication networks, and managing the complexities of large power grids.
The precision in positioning and timing provided by GPS has led to a significant dependency, causing us to often underestimate its importance and assume its availability whenever we need it.
Initially, GPS was created for the purpose of tracking military equipment and vehicles, and it was not foreseen to be utilized in numerous civilian contexts. Recent occurrences have demonstrated that GPS is susceptible to security risks that could cause significant disruption to both personal devices and vital national infrastructure.
Small Cost, Big Consequence
The primary threat originates from a phenomenon that authorities are increasingly apprehensive about, namely the rising trend of utilizing low-cost GPS jammers.
Available for personal use at a minimum cost of $30, GPS jammers, also known as "anti-GPS" devices, can be quite small. Some versions are designed to look like a 12-volt car cigarette lighter power adapter that is linked to an antenna.
Online, these gadgets are advertised as means to enhance personal privacy and obstruct tracking of individuals' locations. However, reports from the UK indicate that such devices have also been misused by criminals and car thieves to mask their unlawful activities.
"The production of these items by Chinese factories is a cause for concern," remarked Peter Large, vice president of Trimble, a company located in Sunnyvale, California that focuses on advanced positioning systems. He warned that if these products become widespread, the impact could be severe.
The operation of GPS jammers involves the interference of frequencies within one of the standard GPS bands. Due to the inherently low power of GPS signals, which transmit at merely 25 watts from satellites situated around 12,500 miles above the Earth, these signals can be easily disrupted or interfered with by receivers, including portable navigation devices.
Due to the common practice of equipping vehicles with onboard GPS receivers by car and truck fleet operators, some drivers resort to using signal jammers to hinder their supervisors from tracking their movements.
According to a November report from the government-established National Positioning, Navigation and Timing (PNT) Advisory Commission, "Our current capabilities to detect and counter GPS jammers are inadequate." The report highlighted that "It took an extended period to identify the device that was interfering with the new GPS landing system at Newark Airport in New Jersey."
GPS signals are set to serve as the foundation for the forthcoming generation of air traffic control systems that oversee aircraft in flight, moving away from the existing system that depends on radar and human intervention.
In addition to overseeing road and marine traffic and managing data and power networks, GPS signals are instrumental in regulating traffic light timings and guaranteeing that automated farming equipment performs accurate plowing and harvesting of fields.
Interfering with any of these systems may lead to severe consequences.
According to Trimble's Large, there is a significant concern that GPS jammers could serve as a weapon.
The National PNT Advisory Commission's report concurred on the necessity of enhancing GPS systems employed in national security operations, such as those in fighter jets and other military technologies, to withstand threats. It also designated GPS as essential infrastructure.
The urgent development and deployment of systems that can efficiently detect, counteract, and deactivate jammers is essential. Additionally, there is a critical need for laws that grant the authority to apprehend and prosecute those who intentionally commit such offenses.
This month, the Royal Academy of Engineering in the UK published a report that reached analogous conclusions.
According to the report, global navigation satellite services (GNSS) have reached a level of convenience and prevalence that users frequently take them for granted. It emphasizes that while the failure of these services in a particular application may only result in minor inconveniences, a more extensive failure affecting multiple systems could have far-reaching and serious implications.
In the United States, GPS jammers are deemed illegal, and similar restrictions apply in numerous European countries. However, the legal framework in some other nations is not as well-defined.
Thai Police Cracked a Case of Two Chinese Suspects Using Signal Jammers to Steal Cars

Thai Police Cracked a Case of Two Chinese Suspects Using Signal Jammers to Steal Cars

Two individuals from China employed remote-controlled signal jammers to execute sophisticated thefts at rest areas along highways. Law enforcement apprehended them in the act and uncovered a technique for extracting funds from credit cards linked to a call center criminal organization.
Authorities in Chachoengsao have been alerted to several incidents of theft occurring at the Bang Pakong highway rest area, where vehicles have been vandalized and valuables, particularly credit cards, have been taken. This situation has resulted in significant concern among motorists traveling along this route.
The police department in Bang Pakong, Chachoengsao, collaborated with the Central Investigation Police to swiftly pursue the suspects. They uncovered significant evidence from the CCTV recordings at each location of the incidents.
The individuals under suspicion seem to be of Chinese origin, frequently employing a comparable method of operation. They are part of an organized group characterized by a distinct division of responsibilities between Zhang, aged 38, and Zheng, aged 31.
On September 15, authorities concluded their investigations at the crime scene and collaboratively apprehended two Chinese suspects at a highway service area located in Khao Din Town, Bang Pakong District, Chachoengsao Province.
Recognizing the clear pattern in the criminals' behavior, the officers dispersed to monitor the vicinity. Upon the arrival of the two suspects, the police held their position until the individuals attempted to unlawfully enter two vehicles, at which point they intervened and apprehended them.
The police subsequently conducted a search of their room, uncovering various items associated with the crime, such as a remote control signal jammers, three mobile phones, a shoulder bag, and they confiscated a car key, a vehicle, along with additional evidence.
The individuals were accused of "jointly attempting to commit theft using a vehicle" and "illegally entering and residing in Saudi Arabia as foreigners." Zhang refuted the allegations, whereas Zheng acknowledged them. Subsequently, they were transferred to investigators from the Crime Suppression Department.
The inquiry revealed that the gang would conceal themselves near parking areas at highway rest stops. Upon observing victims parked and ready to exit their vehicles, the initial group of thieves would deploy signal cell phone blockers to interfere with the remote control signal, thereby preventing the locking of the car.
Subsequently, a different group of offenders would approach the victims and make phone calls in close proximity to divert their attention, ensuring that the victims remained unaware of their unlocked vehicles. Once the victims departed from their cars, another set of criminals would gain access to the vehicle and remove the valuables contained within.
Furthermore, law enforcement discovered that a Thai woman, subsequently recognized as Zheng's girlfriend, Ms. Ketfa Theeranat, aged 20, had been present in the same vehicle as the suspect prior to being transported to the highway rest area.
In the course of a search conducted in Ms. Ketfa Theeranat's apartment located in the Rama 9 District, law enforcement officials discovered ketamine. Consequently, she was apprehended on the charge of "unauthorized possession of psychotropic substances (ketamine)" and was later transported to Makkasan Police Station.
Concurrently, law enforcement uncovered the techniques employed by the suspects to extract funds from the victims' credit cards. The card readers utilized were believed to be associated with international retailers or regions of use. This aligns with the investigative findings, suggesting that the criminal organization may have connections to the call center syndicate involved in defrauding multiple networks.
We will conduct additional inquiries into the case to verify these findings more thoroughly.
Using signal jammers stop employees using cell phones work leads FCC fine

Using signal jammers stop employees using cell phones work leads FCC fine

Previously, the National Labor Relations Board (NLRB) validated an employer's policy that forbids employees from using cell phones at work, citing safety as the primary concern. In a related matter, the Federal Communications Commission (FCC) has recently upheld a fine against an employer for utilizing signal jammers to restrict cell phone usage among employees.
Signal jammers function by suppressing, blocking, or interfering with authorized radio frequencies and communications, and their operation is illegal according to the federal Communications Act of 1934, as amended (the “Act”), with specific limited exceptions. These devices endanger public safety by hindering individuals from making emergency calls to 911, disrupting the communications of first responders, and interfering with essential safety communications in aviation and maritime sectors.
The Act establishes a prohibition on the use or operation of any device intended to transmit energy, communications, or signals via radio within the United States, unless such use is properly licensed or authorized. It also asserts that no individual shall intentionally or maliciously interfere with or disrupt the radio communications of any station that is licensed or authorized under this chapter or operated by the United States Government.
The Act also declares that "No individual shall manufacture, import, sell, offer for sale, or transport any device or household electronic device or system that does not meet the regulations set forth under this section, nor shall they use a device that is not compliant with the regulations promulgated under this section." These regulations necessitate that radio frequency devices be authorized by the Federal Communications Commission prior to their use.
Thus, a jamming device cannot be certified or authorized, given that its primary function is to obstruct or interfere with authorized radio communications. The use of such a device would endanger the integrity of the nation’s communications infrastructure. Consequently, a jamming device does not satisfy the technical standards established by the FCC and is illegal to use in the United States.
The FCC Enforcement Bureau conducted an investigation into a warehouse business in Texas following a complaint from AT&T regarding signal interference. The owner of the business acknowledged the use of a signal jammers to restrict employees from utilizing their cell phones during work hours. The FCC reported that the owner admitted her son had been cautioned by an AT&T representative about the illegality of operating a mobile jammers. Furthermore, the business owner informed FCC agents that she had discarded the jamming device and was not willing to recover it or disclose its location. However, she did propose selling the device to the FCC agents, a suggestion that was declined.

Do GPS jammers exist: work principles
The Global Positioning System, commonly known as GPS, is a satellite-driven navigation system that offers users accurate information regarding positioning, navigation, and timing on a global scale. It functions by utilizing satellites and overseeing ground stations and receivers to identify specific geographic locations.
What does GPS jamming do: technology explained
Distinct classifications of GPS jamming devices involve intentional interference methods aimed at disrupting the normal functionality of GPS receivers. By broadcasting robust signals within the designated GPS jamming frequency bands, these signal jammers can overpower or obstruct weaker signals, complicating or rendering impossible the receivers' ability to secure accurate positioning, navigation, or timing information.
Here are vital aspects to understand about blocking:

  1. Purpose of GPS Jamming: The primary purpose of jamming is to create GPS signal disruption methods. It can be employed for various reasons, including criminal activities, privacy concerns, military operations, or unauthorized actions to undermine the functionality of devices or services.

  2. Types: GPS jammers come in various forms and sizes, ranging from small handheld devices to more powerful stationary or vehicle-mounted systems. Portable jammers can affect localized signals, while larger ones can cover broader regions.

  3. Working Principles: GPS jamming device operation transmit radio frequency (RF) signals in the same frequency bands. The jamming signals overpower or interfere with the weaker signals, disrupting GPS tracking signals. This interference prevents accurate positioning, navigation, or timing calculations.

  4. Impact: Jamming can have significant consequences in different sectors. In civilian applications, it can disrupt navigation systems, affect logistics GPS jammer circuitry and operation, compromise emergency services, and impact industries reliant on precise timing, such as telecommunications and power grids. Jamming can hinder military operations, compromise situational awareness, and disrupt communication systems in military scenarios.

  5. Detection and Mitigation: Detecting blocking incidents can be challenging since jammers often operate covertly. However, various techniques to block GPS signals are employed to identify jamming signals, including RF monitoring, geolocation techniques, and anomaly detection algorithms. To mitigate the effects of jamming, anti-jamming technologies, such as adaptive antenna arrays and receiver algorithms, enhance receiver resilience against jamming attacks.

  6. Regulatory Measures: Many countries have regulations to prohibit the sale, possession, or use of jammers due to their potential negative impact. Jamming signals is illegal in most jurisdictions, and offenders can face severe penalties.

  7. Future Trends: As the technology behind GPS interference continues to evolve. Consequently, research and development efforts are focused on developing more robust anti-jamming solutions, advanced detection techniques, and enhancing security and resilience.

Ensure Your Protection from GPS Tracking Devices

Ensure Your Protection from GPS Tracking Devices

The Washington Times reported that last month, the U.S. Department of Justice presented a brief to the U.S. Court of Appeals. This brief claims that authorities are authorized to obtain cell phone tracking data without probable cause for any potential justification within a 60-day window, allowing emergency services to respond adequately in emergencies.
The government appealed to the district court, where the discussion revolved around location information, including important third-party business records that fell outside the scope of data protection. The judge ruled that this action was a clear violation of the Fourth Amendment. The central issue is that permitting authorities to access personal location data for two months provides them with a detailed insight into a person's life.This data can expose all of an individual's acquaintances, their political ties, colleagues, religious affiliations, personal interests, and even undesirable habits such as gaming. Such sensitive information can be leveraged to intimidate political opponents as well as to uncover organized crime networks.
There exists an additional dimension to this issue. Certain individuals, including drug lords, sexual offenders, and suspected terrorists, might use your phone or other communication devices to track your personal location. To safeguard your privacy and protect your location data, you may wish to consider acquiring an effective tracking gps jammer.
By employing a GPS signal scrambler, one can effectively hinder tracking and strengthen security.
Once GPS devices were introduced, they quickly gained popularity among the public, thanks to their positioning and navigation capabilities. These devices have found utility not only in civilian life but also in military and police operations, as well as among extremist factions. GPS technology can be instrumental in ensuring the safety of family and friends by providing real-time location tracking, which can be accessed via a personal map. This feature allows parents to consistently monitor their children's locations. However, the use of GPS is not without its challenges, as it can be exploited by criminals for nefarious activities.
This account highlights an Ontario man and his family, who were unsettled by the actions of an unidentified individual who installed a GPS tracker under their car. What strategies can be employed to protect your vehicle from this kind of threat?
Certain GPS trackers are acquired under the pretext of fleet tracking; however, these devices can be used clandestinely and illegally on any vehicle. While it is prudent to conduct regular inspections of your car, this may be too cumbersome and may not effectively identify hidden GPS trackers. Professional devices often have corresponding counterparts, and in the case of GPS trackers, this counterpart is a GPS signal jammer. Such a device can disrupt the positioning signals sent by the tracker, thereby alleviating concerns about privacy infringements or security issues.
Instructions for Submitting a Complaint Regarding a Business That Disrupts Phone Signals

Instructions for Submitting a Complaint Regarding a Business That Disrupts Phone Signals

I strongly suspect that a business I frequent is interfering with cell phone signals. I have never been able to make any kind of call while there, and even text messages often fail to send. This is not related to my phone, as I have had the same problem with my last phone on another carrier and my wife's phone (also on Verizon).
My phone thinks the signal is great (3 or 4 bars), but can't even check voicemail. The problem persists - but goes away when I leave the building - until I'm about 10 feet from the front of the location. I suspect the building is made of lead or some other material, because I can pick up Wi-Fi signals (from Comcast, etc.) when I'm inside. I know we're talking about different frequencies, but I think most building materials that block RF do so somewhat indiscriminately.signal jammer
Anyway, I wonder if Verizon could come check it out. If they don't block it, I might have to try a new carrier.
I know how important it is to be able to rely on your service.
Does the problem occur in a different location?
You mentioned that service resumed after leaving the building. Since our cell towers are located outdoors, there are many variables that can affect signal penetration, such as foliage and building materials. This is different from WiFi, which uses a router that allows the signal to be wirelessly accessible inside a building. We do offer network extenders, which can utilize your existing high-speed internet connection to enhance indoor service.cell phone jammer
Comcast WiFi is an outdoor public hotspot - not inside a building at all. Also, I have received strong signals from many off-site WiFi hotspots. I know this is not a foolproof test, but it at least shows that some RF can penetrate buildings very easily. Also, (while I also know this is not perfect) my cell phone reports a strong signal. However, as I said, I cannot even have a poor quality phone conversation. Also, it seems to affect a lot of people, as evidenced by how many people are out making or receiving calls. It only happens at this location. I didn't actually say it happens when I leave the building, I said it happens when I leave the building.
Colossal Jamming Tanks Interfere with the Operation of Every Drone

Colossal Jamming Tanks Interfere with the Operation of Every Drone

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.
Authorities Disable Electronic Signal-Jamming Device in Morgan Hill

Authorities Disable Electronic Signal-Jamming Device in Morgan Hill

MORGAN HILL, Calif. - Authorities have located and disabled an electronic signal-jamming device in Morgan Hill.
The Santa Clara County Emergency Communications Department on Thursday reported that the signal was "disrupting, impeding, and interfering with public safety transmissions."
Officials had noticed interference on a critical communication tower for the past six months, said Morgan Hill police Capt .Mario Ramirez.
The problems intensified over the past week, with neighbors reporting disruptions with their Wi-Fi, satellite and cell-phone service, Ramirez said.
Authorities pinpointed the device to a home near Llagas Road and Christephe Drive, by tracking its radio frequency. Police contacted the resident through a Ring doorbell but the resident wasn't home.
Investigators got a search warrant and forced their way inside
"Upon making entry into the house, officers lost complete radio communication altogether," Ramirez said.
Technicians found two signal jammers and disabled them.
Immediately after that happened, officers radios and cell phones began working again, Ramirez said.
No arrests have been made, and police are analyzing the devices to determine whether the resident could face charges of preventing others from calling 911 or disrupting public safety radio frequencies.
A motive for the jamming isn't known
"I can't imagine a Joe Blow citizen having that equipment to be used for anything other than malicious intent," said Morgan Hill Mayor Rich Constantine, a retired San Jose firefighter .
While Performing a Search, Officers Identified a Signal Jammer

While Performing a Search, Officers Identified a Signal Jammer

During a search associated with a suspected burglary, Vanderburgh officers located a signal jammer.
The Vanderburgh County Sheriff's Office officers uncovered a sophisticated signal jammer while conducting a search, representing the inaugural occasion on which the sheriff's office has encountered such a device.
According to Sheriff Robinson, this device can deactivate Wi-Fi cameras, doorbells, and security systems that rely on radio sensors. Its functionality extends to shutting down all related devices. The primary reason for acquiring such a device is to facilitate wrongdoing and malevolent actions.
According to officials, possessing a signal jammers is not illegal; however, utilizing such a device is considered a federal crime.
According to Sheriff Robinson, the next phase is to engage with lawmakers. He noted, "It is unusual that Indiana does not have a law that directly pertains to the jamming of communications. I think this issue should be tackled, and I will partner with state legislators to close this gap."
According to the sheriff's office, the matter is linked to a reported daytime burglary that took place near the village of Cambridge.
Authorities believe that two men employed sophisticated equipment to carry out an attack on a house.
According to police, a couple returned to their home on Sunday only to find two unidentified men present within.
According to authorities, the two suspects made their getaway in a gray Jeep.
Thanks to a FLOCK camera obtained by the Village of Cambridge via the Sheriff's Office, deputies were positioned advantageously to execute the arrests.
Following a report of a crime, deputies from the Vanderburgh County Sheriff's Office halted Jaime Riveras, a Chilean citizen, on Highway 41.
According to Sheriff Robinson, Riveras reported that he was traveling from St. Louis to Florida and did not pause in Evansville.
According to Sheriff Noah Robinson, a search warrant was secured for all items located in the vehicle, in addition to the witness accounts. This search revealed two cell phones inside the vehicle, which provided GPS data confirming that the suspect vehicle was at Riveras' residence, situated within the premises that had been burglarized.
Riveras has been charged with multiple offenses, one of which involves the alleged use of a signal gps jammer to obstruct crime reports.
The VCSO maintains that this investigation remains active and is currently pursuing leads related to Rivera's associates.
Federal Action on Cell Phone Jammers in Prisons

Federal Action on Cell Phone Jammers in Prisons

This announcement is issued by the office of Attorney General Chris Carr.
Attorney General Chris Carr is calling on the Federal Communications Commission (FCC) to promptly authorize the deployment of cell phone jammers within state prisons and local jails. The FCC currently maintains a ban on the use of cell phone signal jammers, a restriction that applies to both state and local authorities. However, contraband cell phones are being utilized in correctional facilities nationwide to orchestrate violent acts and other criminal endeavors, thereby creating a substantial safety threat to correctional staff, visitors, inmates, and the general public.
Carr stated that the most effective method to safeguard the public from the threats posed by contraband cell phones is to permit the implementation of cell phone jamming technology within correctional facilities. However, he noted that the FCC persistently obstructs these initiatives. He emphasized that this antiquated guidance restricts essential law enforcement resources, endangers correctional officers, and facilitates the growth of criminal organizations both inside and outside of prisons. He reaffirmed their dedication to combating violent crime in all its forms, urging the federal government to eliminate this significant obstacle to public safety.
In the state of Georgia, authorities seized 8,074 contraband cell phones in 2023, with an additional 5,482 confiscated in 2024 to date. Recently, a prominent figure from the infamous "Yves Saint Laurent Squad" gang, currently incarcerated, utilized a contraband cell phone to orchestrate the stabbing of an 88-year-old veteran from Georgia. Furthermore, a gang leader from North Carolina managed to arrange the kidnapping of a prosecutor's father using a cell phone while imprisoned. In California, prison gangs exploit contraband cell phones to facilitate murders and drug trafficking operations within the correctional facilities.
“There are hundreds of examples across the country of how contraband cell phones in the hands of inmates have been used as lethal weapons and enabled them to continue their criminal activities. We are outraged that these individuals are continuing these activities and endangering the public,” said Georgia Department of Corrections Commissioner Tyrone Oliver. “As attempts to infiltrate our prisons with contraband cell phones continue to evolve, access to jamming technology is critical to our ability to combat these attempts. We thank Attorney General Carr for his support of our ongoing commitment to public safety and safe prison operations.”
In his correspondence, Carr observed that the Federal Communications Commission's policy is grounded in legislation established in the early 1990s, prior to the time when incarcerated individuals started utilizing illicit cell phones to organize and partake in unlawful and hazardous actions.
Carr also emphasized that 47 USC § 333 does not prevent the FCC from changing its stance to permit state agencies to utilize cell phone jammers within correctional facilities. Moreover, the U.S. Bureau of Prisons has acknowledged the potential benefits of cell phone jammers and has been authorized to deploy them in multiple federal prisons, including at least one situated in Georgia.
