Russia has figured out how to jam US drones in Syria, officials say

WASHINGTON – According to four U.S. officials, the Russian military has blocked some U.S. military drones that operate in the sky over Syria and are seriously affecting U.S. military operations.

The Russians began blocking a few smaller US drones a few weeks ago, officials said after a series of suspected chemical weapon attacks on civilians in rebel-held eastern Ghouta. The Russian military feared the US military would take revenge and started blocking the GPS systems of the region’s drones, officials said.

Senator Ben Sasse, R-Neb., Responded to the news of the Russian mess on Tuesday by saying, “Russia wants to undermine our interests at every turn.”

“It is crazy to think that Russia is anything but an opponent,” said Sasse.

According to Dr. Todd Humphreys, director of the Radionavigation Laboratory at the University of Texas at Austin, can be straightforward to block or scramble a drone’s reception of a signal from a GPS satellite.

“GPS receivers in most drones can be blocked fairly easily,” he said.

Humphreys, an expert on GPS spoofing and jamming, warns that this could have a significant impact on U.S. drones and could result in malfunction or even crash. “At the very least, this could lead to serious confusion,” said the drone operator on the ground when the drone reports an incorrect position or is lost.

Humphreys said U.S. analysts first caught Russian military drone signal jammer in eastern Ukraine four years ago after they invaded Crimea. He said the jammers were originally recognized as weak signals from space that bounced off the surface of the earth. The jammers “had a fairly significant impact” on the United Nations surveillance drones, which attempted to monitor the area, ground the fleet for days, and stop collecting information from the air.

The Department of Defense won’t rely on operational security to say whether the traffic jam will cause drones to crash. “The US military maintains adequate countermeasures and safeguards to ensure the safety of our manned and unmanned aircraft, our armed forces, and the missions they support,” said Pentagon spokesman Eric Pahon.

However, one official confirmed that the tactic has an operational impact on U.S. military operations in Syria.

The officials said the equipment used was developed by the Russian military and is very sophisticated, and has proven itself to be effective against some encrypted signals and anti-jamming receivers. The drones affected so far are smaller surveillance aircraft in contrast to the larger Predators and Reapers, which are often used in combat environments and can be armed.

Dr. Humphreys says that while the attacks take place in cyberspace, the results are still serious.

“They look a little less hostile than a kinetic bullet, but sometimes the effect can be just as harmful,” he said. “It’s like shooting at them with radio waves instead of bullets.”

Our company provides various types of drone jammers

Our company offers a certain number of tools and technical instruments which make it possible to neutralize a drone by selectively blocking the control signals.

While UAV detection radars, UAV spectrum analyzers and UAV detection sensors are designed to provide timely advice on drone approach, the complete anti-drone system requires the use of devices to eliminate threats from drones entering protected areas.

Our company offers different models of drone jammer, which represent one of the most effective tools to deactivate drones by blocking control signals. Our systems can be equipped with drone jammers used to neutralize UAVs and jammers used to defeat explosive devices.

Drone jammers are used to block signals from drones and force them to land. They cancel the transfer of photo or video material from the drone to the operator and cause the drone to lose control if it carries dangerous substances. In other words, jamming systems provide the intentional emission of radio frequency signals to block UAVs in a particular area.

The jamming systems are controlled by special software which is used to selectively disrupt various command and control communication links used by UAVs and to choose the most appropriate means of responding to emerging threats while mitigating the collateral impact.

IG (Prison): Fixed a jammer

IG (Prison): Suman Gupta discovered misconduct at Ghaghidih Central Prison in Jamshedpur during an assault inspection. Gupta spent over two hours visiting the Central Prison for the first time and assessed the situation at that time, including the visitors, and communicated directly with the prisoners there. The IG prison expressed concern that even if it has been recently repaired, the cheap signal jammer installed in the central prison will not work. Additionally, the search by district police officers was unsuccessful.

Gupta expressed satisfaction with the fact that more than 30 CCTV cameras are working properly. She said she has given specific instructions to ensure that the CCTV camera is not damaged by anyone. Because they function as a third eye in prison. Sources said IG also contacted the inmates to understand their problems. It is worth noting that there are more than 1,450 prisoners, including prisoners in the Ghaghidih Central Prison. In June 2009, the Home Office conducted a survey of the prison and then recommended additional cell phone jammer to the prison. Sources continue to express concern about the situation in the prisons and the government plans to increase surveillance and deploy more security forces.

Inmates cannot use mobile devices because their signals are completely jammed and supervisors are free to use wireless networks (radio, smart phones, etc.). This is not everyone’s solution? I may be wrong, but I want to do it. Despite this, the problem still exists. There is no doubt that in addition to simply receiving calls and text messages, there are many smartphones that can connect to wireless networks. This can be a problem for signal blockers.

When we call someone or text messages, we use the standard GSM wireless frequency. In Europe and Asia, the GSM 900/1800 standard is widely used. It is used in GSM 850/1900 in the United States, Canada, and Latin America. These standards cover the 824 to 1990 MHz frequency band. The Wi-Fi frequency is completely different. When we use a Wi-Fi connection, our operating frequency is 2.4GHz to 2400-2483MHz. Therefore, the entire band that the compiler blocks will be 824-2483 MHz, which is a very broad spectrum. In addition to the wide frequency range that the necessary portable occluders have a configurable output power, it is also possible to work within a clear range to avoid interference that does not interfere with communication. To be honest, not all interferers can accomplish this task. But Jammer-Shop.com can provide the right solution for this particular task.

European countries use blockers to avoid cheating

The development of modern mobile technology has made it easier for teenage students to cheat on exams by texting or reading pictures on their cell phones for fraudulent purposes. Teachers are often too resistant to cheating on their mobile phones. But a university in Italy has its own way of dealing with people, and the use of high-tech means to reduce cheating. The school installed a device on the walls of the school classroom. The device may emit signal jammer and the phone cannot communicate properly.

The school is called Enrico Tosi, located in northern Italy. The school has devised a way to prevent students from using mobile phones to cheat, thanks in large part to military technology. School principals Bonny Tito – Ryan left (Benedetto Di Rienzo) said: “Most schools are trying to confiscate students on the exam before the exam mobile phone, but there are some students who do not give you the phone ” Lane left this week testing the performance of the cell phone jammer for the Italian education ministry. The device, like a box, is called a c-guard, developed by experts from the Italian military and defense industries. The device can block cell phone signals within a 262 foot radius.

The device will eventually be installed by Italian authorities in Italian schools in an effort to prevent students from using their phones to cheat during exams. Ryan says the device has been very successful in the testing process. Some schools in Italy now also plan to open this kind of team in the discontinuation time, as the whole day to start this team can make the normal communication of the teachers also interrupted, it will make the teachers unhappy. “We will minimize the impact,” says Mr. Raine. “Schools, for example, must turn off the device at noon.”

The disadvantages of mobile phones on campus

If students do not behave, how will they be punished if they use their cell phones in the classroom? Most Canadian provinces are specified, the teacher is entitled to classes to take coercive measures “necessary” to maintain the order of teaching, some provinces such as Ontario) will be more “use of cell phones for students” included in the category of ” interference”. teaching order “clearly, Toronto, a high school had a student in the classroom who used cell phones to view e-books, the phone was confiscated by the teacher, student protests in the union were finally rejected.

But schools also have trouble managing students. The Hardy Port School campus on Victoria Island in British Columbia has been flooded with student cell phones, and the gray-colored principal has purchased a “gsm jammer” on campus. While someone is using a cell phone within the monitoring range, the device can quickly interfere with the phone signal and make the user feel embarrassed by the harsh “please give me your phone” sound. Although the use of mobile phones in the school after the device decreased by two thirds, but the students quickly attacked and threatened lawsuits, forcing the main team to dismantle, to avoid the province’s education department in order to “interfere with the legitimate rights and interests of students. ” said disciplinary action.

Cell phone jammers prohibit unpleasant courtesy conversations

Today’s young people are too rude to forbid unpleasant ritual conversations. The cell phone jammer sends signals at the same frequency, and the cellular signal area is disabled.
