U.S. military experts said that in the largest exercise, the U.S. military showed regional GPS signals near the closed exercise site, which means that a large number of domestic civil aviation flights are serious. Sacrifice. The U.S. military believes that the country may have the ability to use handheld gps jammer technology to interfere when fighting its opponents. Therefore, it is prepared to fight under the worst conditions. Without the help of GPS, it has shown us its true power.

Rejecting GPS has become a major problem for US military planners. Companion countries, especially Russia, have used GPS deception and jamming strategies in various training activities to operate near their own borders. We have discussed this situation extensively before, and I encourage you to read this article to understand how the loss of reliable GPS data has had a profound impact on how the United States and its allies deal with such a huge obstacle during the war.

The United States is actively developing GPS jamming technology

The Pentagon has mysteriously tested a technology that can block GPS in a large area, and it is likely that this feature will also be used in the Red Flag 18-1 in the Nellis test and training area. Visual contact and distance affect the way GPS users (especially other aircraft that operate well outside the training area) are affected.

The fact that the Department of Defense will conduct extensive GPS jamming operations in such high-end exercises further proves the extent of the threat posed by these new electronic warfare tactics. It is interesting whether the U.S. Air Force admits that it has actually used it for the "red flag" after the exercise is completed, but given the fact that many positioning, navigation and timing technologies (PNT) have lost GPS signal jammers, in combat, in large military Such consultations during exercises may become more common in the next few years.

12 Antennas Signal Jammer

If what they are doing is jamming, then if you get the timing information from the GPS receiver and your receiver is within range of the wireless jammer, then you will get the timing information from the jammer, yes, but to Include USAF _might_ correct timing information to reduce any side effects of movement in your interference signal...

Interference is a denial of service. If the transmission medium is full of a lot of noise, the digital signal processor cannot decode the effective value from the tape that is transmitting the carrier signal. If too much noise overshadowed the entire signal, then the true signature would be useless.

With the continuous development of the times, after these high-tech products enjoy the convenience and benefits brought by high-tech products, people are also in trouble at the same time, unable to fall asleep due to the sound of the call. Many people are now in this predicament. The situation is that other people can use cell phone trackers or GPS trackers to easily figure out their daily activities. Now people with problems want to find a way to help them solve the problem. Now you will know that signal blocker is very suitable for this situation.

When a man in La Rochelle parked him in the parking lot of Nantes Atlantique Airport, he was fined 2,000 euros for "forgot" to turn off the GPS jammer in the vehicle.

The Nantes court said the fifty-year-old man left the jammer in his car when he flew to Africa in April. The device disrupted the tracking system of the aircraft entering and exiting the airport, causing several flight delays before being located and disabled.

The prosecutor also demanded a three-month suspended sentence for the man.

The use of handheld gps jammer is to deliberately block, interfere or interfere with legal communications (for example, B. mobile phones, text messages, GPS systems and Wi-Fi networks.

French Agence France-Presse said that in France, although law enforcement officers can use GPS jammers under certain circumstances, in France, the public is illegal. However, this has not prevented some motorists from using them to avoid paying road tolls or keeping track of their vehicles. They form bubbles around the vehicle and can block GPS signals for up to 50 meters.

Therefore, you must be cautious when using wireless jammer and cannot be used to disrupt public order. It can only be used in special places and times.

Can't defend against recording? "Being recorded", as the name implies, refers to passively being recorded without one's knowledge. Most of the recorders have "impure motives", either for evidence collection or for other purposes. From the perspective of evidence collection in civil litigation, according to Article 63 of the Civil Procedure Law, recording evidence should belong to audiovisual materials. Then which recording evidence in civil litigation will become an important basis for the judge to determine the facts. Let us now Talk about the recording evidence in civil litigation.

Which recording evidence will be accepted by the judge. According to Article 104 of the Judicial Interpretation of the Civil Procedure Law, “The People’s Court shall organize the parties to cross-examine the authenticity, legality, and relevance of the evidence to be proved, and against the evidence Explaining and debating without the force of proof and the strength of proof. Evidence that can reflect the true situation of the case, is related to the facts to be proved, and whose source and form comply with legal requirements shall be used as the basis for determining the facts of the case. The evidence shall be authentic , Legitimacy, and relevance can be accepted by the court. Therefore, recording evidence should also have the above three characteristics in order to be recognized and adopted by the court.

What kind of recording evidence is deemed to satisfy the three characteristics. According to Article 15 of the Supreme People’s Court on Several Issues Concerning Evidence in the Civil Procedure Law, “If the parties use audiovisual materials as evidence, they shall provide the original carrier for storing the audiovisual materials", Article 71 of the Civil Procedure Law "The people's court shall distinguish the authenticity of audiovisual materials, and combine with other evidence in this case to review and determine whether it can be used as a basis for determining facts", "Judicial Interpretation of the Civil Procedure Law", 100 Article 6 "Evidence formed or obtained by a method that seriously infringes on the lawful rights and interests of others, violates the prohibition of the law, or seriously violates public order and good customs shall not be used as the basis for determining the facts of the case". Generally, recording evidence cannot be used alone as a verdict The basis should be supported by other evidence, and the recording evidence should be provided with the original carrier, such as mobile phones, voice recorders, etc. The source of the recording evidence should be legal, and the recording evidence should not be obtained by infringing on the privacy of others, such as placing secret recording equipment in other people's residences, workplaces, or other illegal means such as coercion, otherwise it will be deemed invalid. In addition, the recording evidence should be unprocessed, continuous, complete, and authentic, and the recorded content should be clear and accurate, and both parties should clearly state the issues discussed and their statements.

How to prevent being recorded by criminals?

The latest L7B recording jammer developed by Jammer-mart is upgraded on the basis of the original equipment. The FPGA-based ultrasonic noise algorithm eliminates the high-frequency noise of the old equipment. It has added various brands of mobile phones and recording equipment that have been on the market in the past two years. The information is very obvious for new recording equipment and mobile phone recording.

The most effective way to prevent recording is to generate random noise signals through the recording masker, which will suppress the voice signal, so that the recording equipment picks up only noise information, but cannot distinguish the voice information and cannot restore it from the recorded signal. The original information is output to ensure the security of voice information. The recording signal jammer adopts security encryption processing, and effectively prevents post-recovery by mixing high and low frequency audio sources.

Our self-developed FPGA-based ultrasound with noise algorithm can effectively interfere with digital devices such as mobile phones and voice recorders, can record noise in, and completely eliminate the harsh sound that a few people can hear. The sound waves emitted by the anti-recorder can only be received by digital products such as mobile phones and voice recorders but cannot be heard by humans. Compared with other anti-recorders, there is no buzzing noise, and it can quietly guard the conversation environment and is not easy to be noticed.
