What is a GPS jammer? Are GPS jammers generally used in cars?

The GPS signal jamming system is designed to suppress the signal of the global satellite navigation GPS system in the range of 1500-1600MHz. The jammer makes it impossible for GPS satellites to monitor the location of cars and all vehicles through GPS, and the GPS jammer device will not interfere with mobile phones and other devices. Gps jammers can range from 5 to 15 meters, which is sufficient for cars and trucks and buses, because the tracker is usually installed in the cab inside the car. After starting the connection through the car cigarette lighter, the device immediately starts to work and generates radio noise (interference) in the range of 1500-1600 MHz (L1/L2) within a 15-meter radius.

GPS equipment will need a phone card. The current location information calculated by the GPS module is uploaded from the communication base station to the positioning server through this card for users to query, and the jammer uses wireless electromagnetic waves to interfere with the communication between the card and the communication base station to achieve The purpose of GPS location cannot be queried by the user.

Working principle of GPS jammer:

Mainly by releasing radio interference waves, the GPS locator can be invalidated within the designated electromagnetic wave band, forming the same electromagnetic environment as the equipment used to block the signal.

There are two ways to shield GPS signals. First: The direct is to remove the two wires of the GPS host. Second: Go to the electronics market to buy a GPS signal jammer, but you must first distinguish what signal tracking method the GPS on your car uses.

There are only two ways of signal tracking: (1) Cell phone signal. (2) Direct satellite tracking signal.

Generally, most GPS tracking signals use mobile phone signals. GPS jammers have the same interference effect on car navigation. GPS used for car navigation is the same as mobile phone signals. It is easily interfered by electronic devices. The signals are shielded, so that all communication devices in the range lose their signals. However, such equipment also has disadvantages for the users. The signal jammer can only be turned on temporarily, and it is impossible to open it forever. As long as he turns off the jammer, the GPS will have the signal again.

Amazing break-in: Was the WiFi for the home security system disrupted?

CHESTER CO., Pa. (WPVI) – A family from Chester County, Pennsylvania, searches for answers after it is discovered an intruder was inside their home.

The suspect was videotaped by his ring doorbell surveillance camera earlier this year. Strangely enough, her surveillance camera caught him coming out but not going inside.

And their home security system never registered that the man was inside.

The case took investigators and security experts by surprise, and you may have asked how secure your camera system is.

The man in question appears to be trying to disassemble the ring camera. He looks at it from different angles and then withdraws to Nemo Perera’s house.

The family observed this while eating out one February evening.

“My heart sank and unfortunately we made the mistake of showing our four young children the video so they would panic. So my wife called the police and we ran home,” said Perera.

What’s worrying is that the Pereras don’t know how the intruder got into their house.

The family has two Wi-Fi networks. One controls his ADT security system, which was partially hard-wired, and the other controls his doorbell system.

However, the system did not detect the intruder inside, nor did ADT motion sensors detect any activity inside.

Perera said, “So we have the ring logs and they show that we left the house at 7:11 pm and the ring stopped working from that point on, with the exception of this one picture that was taken at 7:45 pm.”

Security expert Dave Pearson owns 215 Secure. He has since been hired to improve the Perera’s security system.

“Personally, I think someone turned off the Wi-Fi system. If they know the password to get on the Wi-Fi, that’s a pretty easy way to get in,” Pearson said.

But Perera says he didn’t have standard Wi-Fi passwords and accessing his Wi-Fi networks would have been difficult. He says other security experts told him that he may have been a victim of wireless interference.

There, criminals use an illegal device to send out an explosion of synchronized radio waves that cripple Wi-Fi networks. Despite the hefty fines for owning one, they are easy to find on the internet for a few dollars.

Pearson says they are a concern

Wireless signal jammer is a problem and more of a problem these days. It was certainly a problem for Nemo,” he said.

According to Perera, ADT gave few answers about what happened.

“So we asked our ADT people to explain what was going on and they couldn’t explain it. They’re trying to run it up the flagpole,” Perera said.

Even more amazing, the Pereras say they haven’t found anything stolen.

They suspect that Nemo Perera’s hard drive was copied for business reasons, but security experts say there is no evidence.

Police say they have no suspects or leads, and the Pereras hope someone will spot the intruder and help investigators.

Perera says, “We can’t imagine why. It’s very worrying. To find out what your intention is, it would be very important because I think it mystifies the police too. They wonder why they did that too to have.”

ADT released a statement to Action News stating:

“We investigated Mr. Perera’s claim and approached him directly. We found no evidence of any attempted hacking or jamming attempt.”

Benefits of installing shields in dormitory areas and examination rooms

In recent years, due to the widespread popularity of mobile communication tools such as mobile phones, cheating using mobile communication tools such as mobile phones has become a “secret weapon” for some candidates to improve their test scores. These candidates do not seek hard work on weekdays, but want to use them when taking exams. Some illegal means, or organizations and individuals who listen to some illegal test-disclosure vendors, or provide answers for profit, want to use their mobile phones as answer receiving tools or transmission tools to obtain ideal test scores through cheating, which seriously damages The fairness and seriousness of the exam! It is a great harm to most other students who usually study hard and learn from the truth!

In order to strictly discipline the examination room and ensure fairness and justice for each reference person, installing a mobile phone shielding network intelligent management system or a wireless signal jammer device is one of the most effective ways to prevent candidates from cheating through mobile phones and other communication tools.

According to some school administrators, students now carry a lot of mobile phones. According to the observation and understanding of school administrators in recent years, students use mobile phones as normal applications, but most of them use mobile phones to access the Internet and chat. , Playing games, reading novels, chatting about love, and even more often contacting some idle people in society, which has brought great harm to the education of the school and the growth of students! After the students are checked by the school leaders during the late schedule, it is more difficult to be restrained, managed, and discovered by playing with their mobile phones under the covers.

The school generally recommends that the mobile phone signal shielding system be installed in the dormitory area should only be turned on within two hours after the lights are turned off. The purpose is to enable our students to learn to live and develop good and healthy living habits! Go to bed early and get up early, so that you will not be drowsy due to lack of sleep the next day, unable to concentrate on studying and attending classes.

How to shield a base station within 800M

As we all know, the base station is to enhance the signal, and the shield is to shield the signal. The two conflicts with each other. This is a headache for many government agencies that need a shield. Today, I will show you how a prison with base stations around is fully shielded through our scheme.

It is well known that the prison cannot have a signal, but there is a base station within 800 meters of the prison. The prison has tried many electronic jammer devices, but the effect is not satisfactory. There are always signals in many places, which brings great risks to the prison. Our technicians personally took the equipment to the site to investigate the signal strength and site conditions.

(1) There are many residents around the prison, especially in the southeast direction. The shielding project cannot affect the normal communication of the surrounding residents. Therefore, the selection of the shielding project and the design plan require precise and accurate shielding, which is difficult to design.
(2) The new prison administration office building near the factory area and the old prison administration office building in the living area belong to the police office area and cannot be shielded in principle
(3) There is a large communication tower at the location of the prison office building, which will inevitably cause strong mobile phone signal strength in the entire supervision area, and the field strength value is much higher than that of Canggu. The design of the shielding project is difficult.
(4) There is also a communication tower about 800 meters northwest, which will superimpose the signal strength of mobile phones in the supervision area.

Homemade jammer GPS navigation systems sometimes affect our privacy

GPS navigation systems are becoming more and more popular today. Almost everyone uses it for personal and professional purposes. Therefore, almost everyone has already installed a GPS navigation system in the car, just as we can find the route to any location in seconds. GPS trackers are very popular in travel and mail delivery because it helps them deliver faster to their destination. However, GPS navigation systems can sometimes affect our privacy. When you are tracking or peeping, then the GPS Jammer is a perfect tool for you. Use the GPS Jammer signal to drive and stay invisible anytime, anywhere. Just bring the jammer and turn it on and no one will be able to find our location. As usual, the gps blocker ranges between 5 and 20 meters.

In the era of technology, we need to protect personal privacy

GPS positioning brings a lot of convenience. However, if you do not notice, GPS will quietly display your personal information. The ubiquitous GPS positioning of mobile phones and personal electronic devices continues to determine your whereabouts. In addition, some smart phone applications will also open the location function and display your whereabouts. Therefore, a reliable GPS jammer is needed to maintain personal information security and protect privacy.

Basically, GPS tracking is mainly performed by the vehicle, so it is particularly important to select a gps signal jammer specific to the vehicle.

GPS jammers can effectively block satellite signals, track GPS satellite positioning, and protect your privacy and personal information. In view of the characteristics of all current GPS satellite positioning systems, use this product to effectively explore GPS satellite signals within 2-15 meters to form an effective protection area, so that your whereabouts will not worry about being tracked.

Most GPS jammers are built for military purposes. The purpose is to take the enemy to their exact location or where the enemy drops GPS-guided missiles or bombs. However, there are some civilian uses that interfere with GPS signals, including the ability to hide yourself or your vehicle when the GPS receiver is tracking yourself or your vehicle.

Although GPS jammers have been developed (especially by governments, military organizations, and spy or privacy gadget companies), most civilians do not yet have the technology to create their own homemade devices. This is much more difficult than using basic radio interference to block radio signals.

Example of installation of UAV countermeasure equipment by cultural relics protection unit

UAV “black flying” harm

There are blind spots in the supervision of drones in my country, and the large-scale use of drones brings hidden dangers to public safety. Drones that were originally used for legal purposes are increasingly being used for criminal purposes. The public has become increasingly aware of the harm that drones may cause. UAVs can smuggle drugs; UAVs can spy on privacy/technology; UAVs can affect civil aviation – close to collisions; UAVs may appear in sensitive areas, key locations, cultural heritage protection units and government facilities; UAVs may even Can shoot automatically…

Because the intrusion of drones has brought great harm to everyone’s lives, many units have begun to install drone countermeasures. Let’s take a look at this fixed drone counter independently developed by Texin Electronics. Control the efficiency of the equipment.

On September 20, 2019, Shenzhen Texin Electronics installed a set of fixed drone signal jammer in the cultural relics protection unit of Zunyi City, Guizhou. The interference range of the current frequency hopping aircraft on the market is more than 1 km, and the interference frequency band controls 2.4G and 5.8. G is positioned at 1.5G to achieve the effect of driving away the forced landing. The 1.5km drone cannot fly into the cultural relic unit.

Men’s basketball game reporters restricted due to negative closing venue signal shielding

The 12th National Games enters the final day, and the competition will end today. The closing ceremony of the current National Games will also be held at 4 pm today. According to the notice received by the National Games Propaganda Department last night, the men’s basketball finals interview reporters will implement a quota allocation system, and the closing ceremony will use cell phone signal jammer for communication control.

Powerful signal jammer device

Not long after the men’s basketball semi-finals ended on the evening of the 11th, around 22:00, many reporters covering the National Games received a text message. This official notice from the National Games Propaganda Department stated: Adopt reporters to implement a quota allocation system” and attach the phone number of the forecast name.

The phone of the media director of the Tiexi Gymnasium in Shenyang Division instantly became a “hotline”, and the incoming calls were almost unbroken. More than 50 calls came in within an hour. And these reporters have only one purpose, which is to win interviews for tomorrow’s men’s basketball final.

According to the person in charge, according to the notice issued by the superior, there will be only 20 photojournalists in the men’s basketball final at 13:00 tomorrow, and the relevant photo vest must be obtained to enter the infield. At this time, it is almost impossible for reporters who call to make an appointment to get another photography spot. They can only “register first, and then see the situation.” Regardless of whether it is from the central government, the Liaoning and Guangdong sides in the finals, other provinces, cities, and even Hong Kong, Macao and Taiwan reporters, they can basically get the quota of journalists.

For such a difficult situation, the person in charge is also very embarrassed. “That is 20 places. Xinhua News Agency and CCTV will account for one half. Other mainstream media such as Liaoning and Guangdong will also Give priority to it, so I can only ask media reporters to understand.”

Immediately afterwards, the National Games Propaganda Office issued a notice on the closing ceremony interview. The original text read: “On September 12, during the National Games closing ceremony, communication control will be implemented on the closing ceremony venues, and mobile phone calls cannot be made in the venues. , You can’t use your mobile phone to access the Internet. Please understand that this will cause inconvenience to your work.”

When the reporter called the relevant person in charge of the Propaganda Office, the news was confirmed. As for the consideration of “communication control”, the other party’s initial response was “just received a notice from the superior, and it is not clear.” But then, the Propaganda Office replied: “The main reason for communication control is to worry about malicious hype about the National Games during the closing ceremony, hoping to guide positive reports on the National Games.”

Explain the function of GPS jammer and how to use GPS jammer

When buying and using a vehicle mortgage, it is best to configure a GPS jammer within a certain stage. Especially some car dealers who hand over the car and buy the mortgaged car, in other words, once they receive the car, they can turn on the gps signal jammer and put one in the car, and one more in the car trunk! When the shield is turned on, you can be assured of peace of mind during the round trip with the car. However, the jammer cannot be activated 24 hours a day, so after the safety reaches your own chassis, you must find a technical professional to investigate the GPS by yourself, and also modify the GPS positioning equipment and mortise locks, key changes and other security guards to prevent mistakes. just in case.

1. Understand the GPS jammer
GPS jammers (jammers) can reasonably prevent tracking by GPS communication satellites, reasonably affect GPS communication satellite signals, and maintain your track privacy protection and information business secrets.

2. The function of GPS jammer
The GPS signal is the same as the signal on the mobile phone, and it is very susceptible to the influence of electronic components. The signal jammer can shield all the signals in a certain range, so that all the communication devices in the range lose the signal. The installation of a GPS locator on the car enables buyers to easily find their own car on the GPS monitoring management platform. As everyone knows, such a good product is also found by criminals to find loopholes. If you buy a signal blocker on Taobao, Turn on when the car is stolen, there will be no signal in the car, and the car will go offline on the service platform, as if the whereabouts of the car are unknown, you can’t find it anyway.

3. Disadvantages of GPS locator
I have to admit that the GPS jammer also has disadvantages for the user. The signal jammer is only temporarily turned on, and it is unlikely to be turned on all the time. If he turns off the jammer, the GPS locator will have a signal again. Drivers can quickly find the stolen car based on precise positioning information.

gps car signal jammer

In addition to signal jammers, some people will also say that they will use signal detectors to find out and destroy GPS locators. Yes, this is also an objective fact, but this is only valid for some GPS devices. If the GPS tracker is in the dormant state most of the time, the signal detector will not be able to detect it! what happened?

For example, some ultra-long standby GPS locators can only be awakened once a day. After being awakened, the precise positioning information of the vehicle is sent back to the buyer’s network platform and then it enters the dormant state. In the dormant state, it is Without a signal, it is absolutely impossible for car thieves to detect it! In addition, it is also free of wireless network installation. There is no wiring on the surface of the machine and equipment. It can be placed anywhere on the car (if it does not have to be placed in an area blocked by the signal). It is very concealed for engineering safety.

How to use GPS jammer

The GPS jammer can indeed shield GPS signals, but it has disadvantages. It will shield all signals in the car! In other words, a car thief is unlikely to use communication devices such as mobile phones near the car. If he cannot find and destroy the GPS device, he has to always turn on the shield, otherwise, he will eventually expose his behavior. Therefore, how to use GPS jammers must ensure the following:
1. The GPS jammer can be used when picking up the car, so even if there are tricks, there is no need to be afraid.
2. When you return to your own area, you don’t need to shut down, first find an auto repair shop to carry out major demolition. Make sure it is clean and tidy before closing.
3. For safety reasons, a car can continue to use GPS jammers for more than half a year. And to ensure that the GPS jammer can work normally for 24 hours.

Install a weighbridge jammer, one-third less cargo

Recently, the Nanyang Police Station of the Shijiazhuang Chang’an Sub-bureau destroyed a criminal gang that used weighbridge jammer to steal property. Xu is the person in charge of a heating pipe fittings factory. Since the beginning of this year, when his factory sold waste heating pipe fittings, the number of the factory did not match the actual quantity. It was suspected that someone had done tricks on the floor scale.

super power signal jammers

On October 19, 2020, Xu also negotiated a deal with Liu, who purchased waste heating pipe fittings. Liu Moumou took someone to install the accessories of a certain Xu truck and drag it to the weighing house in the west of a certain village in Chang’an District. After weighing the pounds, Xu felt that there was no shortage of cargo in this truck, so he reported the case. The police from the Nanyang Police Station rushed to the scene immediately and took control of Liu Xumou and others and the weighing house owner Dong Xumou. The weighing jammer was seized on the weighbridge at the scene.

After interrogation, Liu XX and Dong XX confessed that before the weighing, one of Liu’s parties who purchased the accessories had sent someone to install the jammer on the floor scale, and controlled the floor scale when weighing to reduce the weight of the goods. After calculation, the weight of Xu’s vehicle accessories was reduced by one-third, and the direct economic loss reached more than 23,000 yuan.

At present, the criminal suspects Liu Moumou and Dong Moumou have been detained under criminal law, and the case is under further trial.
