GPS technology in vehicles may be interfered with by so-called jammers or completely blocked. In the short or long term, the electromagnetic waves will overlap the signal from the transmitter, making them unusable. For this, the mobile jammer must simply be located near the GPS device. The use of signal jammer equipment is generally prohibited in the United States, but this interference must be distinguished from more complex GPS spoofing, which not only interferes with transmission, but also the transmission of fully manipulated data.

All parties, including the media, are banned from flying drones

All parties, including media practitioners, are reminded not to fly drones anywhere in the country while the Movement Control Ordinance (MCO) is enforced through May 12.

Supt Rasha Azaldin Shafii, head of the drone unit of the Royal Malaysia Police, Air Operation (PGU), said flying drones without permission from the Malaysian Civil Aviation Authority (CAAM) is a violation of the Malaysian Civil Aviation Ordinance 2016 (MCAR 2016).

“Anyone who operates a drone without a permit can be punished with a minimum fine of 50,000 RM or a prison sentence of three years for individuals, while companies can expect a maximum fine of 100,000 RM.

“Please note that not all parties are allowed to fly drones unless they have permission from CAAM and the police,” he told Bernama.

He said throughout the implementation of the MCO, police had discovered four cases of illegal use of drones across the country.

“Further investigations into the cases are ongoing and the police are ready to use the drone jammer device to ensure that no drones are flown anywhere without authorization,” he said.

According to Rasha Azaldin, drones will be used specifically for nationwide aerial surveillance, including in areas under the expanded MCO.

“The use of drone technology has definitely been effective in making announcements and bringing back memories of COVID-19 throughout the MCO period,” he said.

On April 7th, CAAM authorized the PGU Drone Unit to operate the unmanned aircraft system or drones for surveillance and enforcement purposes during the MCO.

CAAM also announced that the drone operation would be led by the police in collaboration with the Malaysian armed forces and three private drone companies.

GPS disturbed: Russia is playing with America’s F-35

Russian forces have blocked GPS systems in the Middle East. The electronic warfare campaign could affect US forces gathering in the region ahead of possible strikes against Iran.

“Since last spring, pilots flying through the Middle East, particularly in Syria, have found that their GPS systems have displayed the wrong location or have stopped working,” The Times of Israel reported in late June 2019.

According to a US-based researcher, the signal that has disrupted satellite navigation for aircraft flying through Israeli airspace in recent weeks comes from a Russian air force base in Syria.

This disruption in the reception of the Global Positioning System does not appear to be specifically aimed at Israel, but rather the Jewish state is likely to be collateral damage as Moscow tries to protect its troops from drone attacks and assert its dominance in the field of electronics, Professor Todd Humphreys at the University of Texas, told The Times of Israel.

cheap signal jammers

Israeli sources “are increasingly convinced” that three weeks of GPS glitches for civilian flights is a side effect of Russian interference and spoofing in Syria, Breaking Defense reported. “Moscow is trying to interfere with both Western aircraft – including state-of-the-art secret F-22 and F-35 – and improvised terrorist drones.”

The US Air Force, which will take off in April 2019, has dispatched F-22 and F-35 stealth fighters to Qatar and the United Arab Emirates, respectively, to strengthen the armed forces, while Washington, following the decision of the US President Donald Trump clashes with Tehran unilaterally for the United States to withdraw from the agreement to limit Iran’s nuclear program.

Now the situation is rife with rumors as the Israeli government eschews any official statement and continues to investigate other sources. But if Russia actually accidentally disrupts a friendly nation’s GPS, then why didn’t they stop?

The answer could lie within the confines of Russian electronic warfare, which, while far more effective than the US military [electronic warfare], is still based more on raw power than on precise aiming.

The International Federation of Air Line Pilots’ Associations and the Israeli Airports Authority announced in late June 2019 that many flights lost GPS satellite signal while flying in or out of Ben Gurion International in Israel, Breaking Defense reported. According to the IAA, there is no risk to passengers. The affected aircraft simply switched to backup systems.

“Interestingly, ground-based GPS systems are not affected,” stated Breaking Defense. “That makes the aviation GPS malfunction suspiciously specific – another sign that it is not a simple glitch, but some kind of electronic weapon. And the Russians have invested heavily in powerful spoofing systems, the wrong GPS Send signals that are up to 500 times stronger than the real ones, which leads civilian navigators astray for miles. ”

Russia also disrupted GPS in Europe

“In late October [2018], encrypted GPS signals were first discovered during NATO’s large-scale Trident Juncture exercises in Norway,” Defense News reported.

“Norwegian Intelligence said it was tracking the source of the signal blocker to a Russian military base on the nearby heavily fortified Kola Peninsula. Finnish Military Intelligence said Norway’s analysis reflected its own research and assessments.”

In late 2018, Finland and Norway filed complaints with Russia about the disruptions. “Defense and civil aviation chiefs in Finland and Norway warned that the GPS jammer posed a serious risk to military and commercial aircraft using the affected airspace in the far north,” said Defense News.

“Russia has asked (us) to provide evidence. We gave them the proof, ”Norwegian Defense Minister Frank Bakke-Jensen told Arctic Today. The evidence consisted of measurements that showed that signals had been jammed.

“Russia said, ‘Thank you, we will come back when our experts review,” said Bakke-Jensen. “To have such a response from Russia is a positive thing,” he said.

Bakke-Jensen implied the interference was intentional. “They trained very close to the border and they knew that this would affect areas on the other side,” Bakke-Jensen said of the Russians.

The US Army plans to test jam-resistant GPS systems in Europe to counter Russian electronic warfare.

The 2nd Cavalry Regiment of the Army in Germany is to receive the new interference-resistant GPS by the end of 2019.

GPS Jamming Experiment

Chronos Technology Ltd successfully demonstrated the GPS Jammer Triggered Camera technology during official GPS jamming tests at the Sennybridge Military Jammer Training Area in Wales at the end of August 2015, Lydbrook , Gloucestershire, UK.

JammerCam ™ GPS triggered camera technology Jammer was jointly developed by the Department of Electrical and Electronic Engineering at the University of Bath and Chronos Technology Ltd. This development took place within the framework of a project called “AJR”. Internet of Sensors “Feasibility study competition

The trials allowed JammerCam ™ units to be tested in an outdoor environment with a range of GPS jammer hidden in vehicles passing alone or in convoys, including cars, vans and shipping containers. Jammer-triggered camera sensor technology successfully identified and photographed the vehicle hosted by the jammer in all test cases and at all speeds and powers. Either way, the vehicle was taken at the center of the frame so that only one frame was needed, which significantly reduced the bandwidth needed between the sensor and the web server.

The photo identifying the vehicle with jammer would then be sent over a mobile network to a web server where it is distributed as a hyperlink to target email addresses. The image can then be called up as actionable intelligence within seconds of the camera taking the jammer.

Professor Charles Curry, Managing Director of Chronos, explained: “A proof of concept system was demonstrated during the Sennybridge GPS Jamming trials in 2014 by the University of Bath. We then had to overcome some significant challenges, not the least of which was to make the system fully automatic so that it only took a photo of the vehicle hosting the jammer. We know that even low powered cigarette lighter style jammers emit enough detectable interference to create a power bubble around the vehicle, making it very difficult to determine which vehicle in heavy traffic is hosting the jammer. Our two biggest discoveries were to identify the vehicle in a convoy hosting the jammer, and detect and catch a shipping container with a low-powered jammer inside.

South African prison facility jammer

Prison leaders use signal jamming devices to prevent inmates from using cell phones in prisons.

A Department of Corrections document seen by Sowetan says he is in talks with SA’s Independent Communications Authority to “explore various technical and legal solutions, including, but not limited to, cell phone jamming.” .

The ministry also wants to expand the installation of cell phone detection systems in various prisons to help officials identify and remove unauthorized communication devices.

Currently, cell phone detectors are installed in 39 prisons while 14 other body scanners will be placed in seven prisons to help authorities stop cell phone smuggling.

According to Icasa’s Guide to the Use of the Frequency Spectrum, the use of any jamming device, including jamming of mobile phones, is prohibited in South Africa for reasons of security and effective electronic communications.

But after the use of a signal jamming device during President Jacob Zuma’s address, Icasa said that the use of jamming devices by an entity other than the national security cluster departments is not authorized and authorized. At the time, the authority said that national security cluster departments could, when supported by relevant security legislation, deploy the use of jammers as part of, among other things, security functions. of State.

Several media companies and the SA National Editors Forum have appealed the decision of the Western Cape High Court dismissing their request to declare the use of the signal scrambling device illegal in Parliament. The prisoners at Pollsmoor in Cape Town recently caused a stir when they created their own Facebook page and started posting pictures of themselves in their orange prison clothes.

In June, Free State Presiding Judge Mahube Molemela wrote a report after conducting a forensic inspection at Zonderwater Prison in Cullinan (Tshwane).

Molemela found that the prison had a serious problem with drug and cell phone smuggling, mainly due to staff shortages and overcrowding in communal cells.

But the judge also found that because the prison had basic adult education and training for learners and 11 students from the University of SA, it should allow prisoners to have laptops in their cells.

“There is no reason why laptops should not be allowed in student cells. A laptop computer that does not have Internet access cannot pose a threat to the security of the facility,” Molemela said.

South African courts have already ruled in favor of student prisoners at higher education institutions who wish to access the internet for their studies, but this must be monitored and used “strictly for studying”.

Icasa’s Paseka Maleka did not respond to requests for comment made Thursday. Logan Maistry of Corrections said he needed more time to respond.

Truth|Does the cell phone signal jammer affect the human body?

Generally, people have inexplicable rejection of wireless devices. They always think that the signals emitted by wireless electronic products will affect their health. So, today, let’s talk about whether cell phone signal jammers have any impact on human health.

First of all, concerns about radiation from electronic products have always been a controversial issue among the people. Because we know that all electronic products have radiation, but different products have different amounts of radiation. Generally, the equipment of regular cell phone jammer will be monitored by the National Center for Disease Control and Prevention before leaving the factory. At present, the National Standards of the People’s Republic of China “Electromagnetic Radiation Protection Regulations” (GB8702-88) and the People’s Republic of China Environmental Radio Wave Hygiene Standards (GB9175-88), according to the national standard radiation level requirements, are allowed only after manufacturers who produce electronic products have passed the test. sell. And after installation on site, it also needs to undergo radiation testing by the National Center for Disease Control and Prevention. For engineering sites that meet national standards, the National Center for Disease Control and Prevention will issue an electromagnetic radiation testing report.

After testing, electronic products that meet the national standard radiation level requirements have no effect on the human body, so there is no need to worry about whether the signal radiation of the mobile phone signal jammer will affect the health of the body. In addition, according to the conversion of relevant data, the amount of radiation from the mobile phone to the human body should be the largest, and the radiation from the shield to the human body is almost negligible compared with the radiation of the mobile phone we use daily.

China’s self-developed UAV jammer looks strange like a chainsaw

The first is discovery. Almost all current large-scale advanced drones use stealth design, which makes it difficult to discover their whereabouts. At this time, the long-wave radar is used. The current stealth drones are mainly effective for centimeter-wave radars, but for long-wave radars, drones are almost impossible to stealth. Long-wave radar can provide early warning and azimuth indication for stealth drones, laying the foundation for subsequent strategy development.

The second is interference. Utilizing ultra-high-power drone jammer to transmit strong electronic waves to the UAV, blinding the UAV’s radar, cutting off the “umbilical cord” connection between the UAV and the space-based satellite and parent base, making it unable to receive remote control instruction. * Is to take over. When the UAV’s accusation command is interfered by strong electronic waves, it will retransmit a fake GPS parameter to the UAV to make it fly according to the path desired by the trapper, and finally control it to land smoothly to the designated location.

However, the theory is so, but in fact, because the enemy UAV also has information encryption and anti-interference methods, it is not easy to operate. All military powers are sparing no effort to develop technologies that can “trap” drones. For example, Russia’s “automobile field” is one of the few electronic countermeasure systems that can “trap” advanced drones. It consists of dozens of vehicles, loaded with radar, electronic jamming equipment, and ground command equipment, which can easily penetrate The enemy’s electronic jamming waves and avionics resistance.

Talking about the advantages of UAV jammers

Today, more and more people complain that their personal lives are often exposed to unauthorized drones. UAVs are very famous today, they are usually used to capture important events or certain objects from the air. Since these technologies do not stand in the same place, new and more advanced models of drones and squares are being created every day that can turn your personal life into the object of particularly curious espionage.

Intruders are one kilometer or more away from objects protected by traditional security systems. They can conduct industrial espionage from the air, monitor private life, throw prohibited items around guards or export valuables, and drugs bypass control points and inspections. Considering the growing threat of terrorism around the world, the use of drones carrying explosive devices can be expected to attack crowded locations and sensitive infrastructure elements. Equally dangerous is the drone, whose operators simply lose control and stay away. Such drones are in the airport area even at very high altitudes, and can enter the engine of the flying or landing aircraft and turn off the power cord.

Thieves can obtain detailed information about the location of guards and installed CCTV cameras, the location of storage facilities, and the number of any secret equipment. As you can see, with the help of drones, detailed information can be obtained. Therefore, if you want to protect yourself from unauthorized entry into your personal life or business, then you should know what drone jamming technology is. The jammers of quadcopters and drones are high-power devices that can block the audio and video transmission of information. These devices are beneficial because they can store confidential materials.

When choosing a drone jammer, please pay attention to the spectrum of the blocking frequency. The drone jammer is a powerful device that can effectively prevent the operation of the following frequencies: video transmission frequency (2.4G WIFI 2400-2500MHz 20W); remote control frequency (2.4G WIFI 2400-2500MHz 20W); ˚F video Transmission and remote radio control (5.8G 5.5-5.9MHz 2W) rate; ˚F remote radio control nuclear rate (868-912 MHz, 860-920MHz 25W, 20W 433-434MHz); GPS frequency L1 1575 MHz 40W.

The anti-drone jammer is equipped with multiple pin antennas. The length of the antenna can be different. The blocking radius of the suppressor can also vary according to the signal strength, location, and remoteness of the basic control. The more powerful the function you choose, the larger the blocking radius. It is important to note that the jammer has a low-noise built-in fan. With such a reliable cooling system, you can stay calm and overheating will not pose a threat to you.

Most drone radio jammers have unlimited working hours, so you can use it for a long time. Signal jammer is specifically used for advantageous purposes to ensure control of the territory, prevent industrial espionage, counter-terrorism purposes, attempts to move narcotic substances, certain types of weapons, personal family information or commercial espionage, etc. 2.4 GHz jammer for drones-ideal for any citizen who cares about privacy.

In addition, we will help you choose a suppressor that meets all your requirements.

Criminals complete the theft in 20 seconds

Recently, the border defense detachment of Dongguan City, Guangdong reported that a series of car property theft cases that occurred in service areas such as Guangzhou-Shenzhen Expressway Houjie this year have been solved. Criminal gangs used signal jammer to transmit signal interference, causing car owners to lock the car and steal the car. Inside property.

pocket gps signal jammer

From the surveillance video, we can see that in the Dalingshan service area of ​​the Guangzhou-Shenzhen Expressway, a man wearing a white short-sleeved T-shirt got off a black car. He seemed to be moving his muscles and bones. In fact, he was just pretending to rest and looking for the target of the crime. . Soon, a gray SUV drove into the service area and stopped. A man and a woman in the car closed the door and left.

At this time, the criminal suspect appeared again, and saw him approaching the SUV car casually, opened the door easily, quickly got something from the car, turned around and got into the corresponding vehicle and quickly escaped. The entire theft process took less than 20 seconds.

In the end, the Hunan suspect Tan and his associates were arrested by the police in a hotel in Dongguan at the end of September. In the face of hard evidence, Tan and his associates confessed to the crime.

How to deal with “car jammers”?

①When traveling or shopping for parking, try to choose a public parking lot with camera monitoring. Especially when parking overnight, try to park in a parking lot that is supervised by someone.

②When locking the car, pay attention to the phenomenon of locking the car. For example, when some cars are locked, the two rearview mirrors will be retracted; when some cars are locked, the turn signal will flash twice, etc. When an abnormal lock is found in the use of an electronic lock, a manual lock should be used to increase the safety factor and try to avoid unnecessary losses.

③When you lock the car, pay attention to whether there are suspicious people around. Before you leave the car, pull the car door with your hands to make sure it is locked.

④Don’t put valuables such as leather bags, mobile phones, cash, etc. in the car, so as not to let criminals catch them.
