GIDAS’s real-time interference detection makes the navigation system safer

It is estimated that there are currently the same number of navigation receivers on Earth as humans. Positions, navigation and time signals from space-based constellations such as Galileo and GPS form an invisible, indispensable infrastructure that lays the foundation for many modern aspects of modern life (communication, energy, and transportation).

Satellite navigation is helping to control more and more planes, ships, trains and self-driving cars. At the same time, navigation-based time stamps can mark real financial transactions worth billions of euros and coordinate the synchronization of the grid. Satellite navigation is always active and available anywhere on the planet. Therefore, it is easy to take usability for granted. These signals from space are equally important, and they are also susceptible to ground interference.

Andreas Lesch of OHB Digital Solutions in Austria said: “It’s just a matter of output power.” “The navigation signal on the ground corresponds to the light of the 60-watt lamp on the satellite. For Galileo, its distance in space is about 23,222 kilometers. These weaker signals may be accidentally or deliberately destroyed by stronger local radio signals or even misleading false navigation signals (so-called deception).”

“We have developed a new GNSS interference detection and analysis system, GIDAS, to protect critical infrastructure from damage or deception by continuously monitoring important signal frequency bands. In this way, GIDAS can trigger alarms in real time, determine the nature of the failure, and then determine the cause of the failure. The location of those dangerous portable devices so that the authorities can take immediate remedial measures.”

Although at least three stations are required to locate interference sources connected to the entire monitoring center, GIDAS can provide interference detection and orientation through a single reporting station. Monitoring centers can also be connected to each other, which makes the GIDAS system easy to expand, from ensuring a single port, airport or key location of the system to the entire city or region.

“People are only catching up with the severity of this problem now,” Andreas added. “In parts of Europe, the highest density surveys show about three to four signal jammers per hour.

These small devices are technically illegal, but can be purchased online for a few hundred dollars or less, and are usually sold as data protection devices. The sales range of the jammer is only a few meters, but the actual use range may reach tens of meters or more, which may cause unnecessary widespread interference. For example, the famous American truck driver takes the jammer while sailing at Newark Airport as long as he passes. Will shut down the system.

Analysis: Mini GPS jammer

If you spend enough time browsing eBay to break down interesting electronic gadgets, you’re bound to see suggestions for some questionable gadgets. This is how I recently became aware of these tiny GPS jammer that plug directly into an automotive 12v socket. Delivered to your doorstep for less than $ 10, it seemed like a perfect device to rip open in the name of science.

Now you may be wondering what legitimate uses such a device could have. As far as I know there aren’t any. The only reason you’d want to interfere with GPS signals in and around a vehicle is if you’re trying to get away with something that you shouldn’t be doing. Perhaps you’re driving a haunted company car and want a quick two hour nap in a parking lot, or you might want to disable the car’s built-in GPS that you stole just long enough for you to take it to the car store. You know how to do it.

However, we are not going to delve into the potentially nefarious reasons this device exists. Hackers have never been too picky about the devices they investigate and experiment with, and there is no reason why we should start now. Instead, let’s take this gray area hardware for a test drive and see what moves it.

While the GPS constellation’s average altitude of 20,200 km (12,550 miles) may not be quite as high as that of communications satellites in geosynchronous orbit, they are still quite a long way off. Given this incredible distance and the size of the antenna on most GPS equipped devices, it’s no wonder the received signal is very weak. So weak, in fact, that it is generally below the noise floor. Only with clever algorithms and a dash of wizardry can your phone turn that whisper from the stars into something that resembles useful information.

It is this fragility that makes this type of inexpensive jammer possible. It doesn’t take much to overwhelm the legitimate signal. Remember, a device like this does not attempt to mimic a GPS satellite, but simply emits loud enough nonsense that the real satellite can no longer be heard.

When the jammer is on, we can clearly see how the already meager signal is absolutely wiped out by the patterns sent by the device.

There is just no competition. The legitimate signal is tens of thousands of miles away, and this thing is screaming its head within easy reach. I haven’t tested the range of this device, mainly because I didn’t want it to be turned on for longer than necessary, but it is capable of doing the deed at least several meters.

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.

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.

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.

A two-function signal jammer

If you are a teacher who goes to the exam room often, you may want a cell phone signal jammer to make the student more aware. If you are a businessman who wants to keep trade secrets, you might fear that one day you will be tracked because someone may already have a GPS locator installed in your car. Then you can install a GPS signal jammer.

Although some people may not be teachers or businessmen, but only encountered these two problems. More and more people think that it is not easy to keep secrets in modern society because there is too much spyware and spyware. Social software and the Internet have spread enough scandals around the world. There is no secret. It’s another people’s nightmare.

The man set up a jammer to interfere with the aircraft GPS signal? The truth is…

GPS navigation signal is an important technical guarantee for aircraft flight safety. The flight crew of a civil airliner that landed at Liuzhou Airport not long ago reported that the aircraft was about 8 kilometers above the runway when it was descending and preparing to land. GPS signals began to be interfered by radio until the distance About 4 kilometers above the runway, the GPS interference signal disappeared, and the length of time the passenger aircraft was interfered on different flights was different. The shortest time for the passenger aircraft GPS to be interfered was 60 seconds, and the longest time was 125 seconds.

The reporter learned from the Liuzhou Radio Monitoring Center that recently, the center used technical means to jointly enforce the law with relevant departments. This case of civil aviation passenger aircraft GPS interference was seized and handled, eliminating potential safety hazards.

It is understood that on June 28, Liuzhou Airport submitted a radio interference complaint form to Liuzhou Radio Monitoring Center: The GPS signal was severely interfered by the GPS signal while the civil airliner was preparing to land on the runway of Liuzhou Airport recently, resulting in loss of GPS signal and interference. The worst airliner lost GPS signal for up to two minutes. The GPS signal was interfered with and affected the approach and landing of the aircraft. Some flight crews adopted the termination of the RNP approach procedure and used visual control of the aircraft to land, which seriously affected the approach and landing of the civil aviation aircraft and brought security risks to flight safety.

After receiving the complaint, the Liuzhou Radio Monitoring Center dispatched monitoring personnel and dispatched mobile monitoring vehicles to carry out carpet radio monitoring and interference investigations on the area under the GPS interference route. It was found that the source of the interference was set by the Liuzhou Power Supply Bureau on Ruilong Road. A GPS signal jammer in a second-hand car warehouse next to the Fort Substation. After questioning, the owner of the car warehouse confessed that the jammer was purchased from Taobao and it was used to shield the GPS signals of cars in the warehouse to prevent vehicle positioning information from being discovered.

On July 21, Liuzhou Radio Monitoring Center, Municipal Public Security Bureau Airport Branch, and Liuzhou Airport launched a joint operation to investigate and deal with the illegally installed GPS signal jammer in the warehouse. The staff of Liuzhou Radio Monitoring Center and the Public Security Bureau conducted a preliminary inquiry and investigation of the warehouse owner. After that, the public security police seized the GPS signal jammer according to law and brought the warehouse owner back to the Public Security Bureau for further investigation.

At this point, the GPS signals of all civil aviation aircraft that landed at Liuzhou Airport have returned to normal, and the radio signals that interfered with the GPS positioning of the civil aviation aircraft have completely disappeared, and the hidden dangers affecting aviation safety have been eliminated.

Contraband in prison: cell phone

Another way for prisoners to evade prison wiretapping is to obtain their own mobile phones. The prison authorities found that prison inmates can easily get their previous mobile phones (which can be activated with a charger). One tip came from the mother of a prisoner who complained in a jail guard at a Texas state jail that her son’s cell phone was not well received.

In addition to known prisoners committing crimes by telephone, the accessibility of mobile phones has become a serious problem in prisons. When members of the prison have mobile phones, gangs can organize themselves more easily. For example, it is reported that in 2006, gang leaders imprisoned in Brazil used their mobile phones to plot a large-scale simultaneous riot, with the purpose of proving their influence and even being locked up in prison. The group caused an uprising in more than 70 prisons. At the same time, members outside the prison caused riots and caused serious damage to public buses and police stations. Gangs have also surpassed American prison cells, where gang leaders can exercise power from inside the prison walls and even order the killing of gangs.

So, how do prisoners use mobile phones? Obviously, it is well known that visitors and corrupt prison guards provide these calls to prisoners. To help eliminate this phenomenon, some states try to combat it by making the consequences more serious. The court allowed penalties for people who were discovered with a mobile phone, because these conversations cannot be monitored and are therefore a security threat. Several states have criminalized the possession of mobile phones by prisoners, while others hope to increase this crime to a felony level.

Unfortunately, for prisons, cell phone signal jammer (interfering with radio waves to prevent cell phone communication) from the “prison jamming” system is not a viable option-at least in the United States, because cell phone jamming devices are illegal under property laws. In addition, even if the prison obtains permission to block cell phone signals, jammers may also interrupt the prison’s radio signals. Despite these concerns, prisons in other countries (such as England) have also implemented jammers due to the widespread use of mobile phones.

Whether the signal shielding device can shield all communication signals

Nowadays, the emergence of shielding device has solved many hidden dangers of disrupting the order in the examination room, so that candidates can take the exam in a fair environment. The principle of this kind of test signal jammer is actually to block the communication signal of the mobile phone by isolating the electronic signal, which can prevent the phenomenon of using the mobile phone to cheat.

Generally speaking, the effective range is within a radius of 0 to 30 meters. Generally, a low-power test signal jammer is enough to cover an entire classroom, which meets the needs of the test room for shielding signals, and is especially suitable for schools to purchase signals for the test room. shield.

Can the test signal jammer block all communication signals? Speaking of it, many people are unfamiliar with test signal jammers. In fact, it has been widely used in the college entrance examination examination room. In the college entrance examination last year, many examination rooms installed this kind of equipment and received it. Many good responses have been proven to have a good effect on preventing electronic signal cheating. Starting this year, it has been vigorously promoted to allow more examination rooms to install shields.
