Gps Jamming Problem Aviation

2024年7月15日[月] 15:37:39

Estonia has accused neighbouring Russia of jamming GPS navigation devices in airspace above the Baltic states, echoing concerns from airlines that say they have been contending with such interference for months.

Estonian Foreign Minister Margus Tsahkna's accusation, for which he provided no proof, followed Finnair's (FIA1S.HE), opens new tab decision to pause flights to Tartu in eastern Estonia for one month due to GPS disturbances. The Kremlin did not immediately respond to requests for comment.

There have been reports of a rise in GPS interference around the world, particularly since last year, raising fears of an increased risk of accidents if planes veer off-course.

what Is Gps Jamming and Spoofing?
GPS, short for Global Positioning System, is a network of satellites and receiving devices used for positioning, navigation and timing on Earth in everything from ships and planes to cars.

GPS is one of the more important navigation tools in aviation, which has replaced expensive ground devices that would transmit radio beams to guide planes towards landing.

However, it is also fairly easy using store-bought tools to block or distort GPS signals and militaries have invested in technology that can do so.

GPS jamming uses a frequency transmitting device to block or interfere with radio communications, usually by broadcasting signals from the ground that are stronger than satellite-based signals.

Spoofing might involve one country's military sending false GPS signals to an enemy plane or drone to hinder its ability to function and is often considered more disruptive and dangerous than signal jamming.

The problem for commercial aviation comes if that false signal is picked up by a GPS receiver in a passenger plane, potentially confusing the pilot and air traffic control by showing the wrong time or coordinates without warning.

where Does It Occur?
In December, aviation advisory body OPSGROUP flagged a surge in spoofing affecting private and commercial jets around the Middle East, including Iraq, Iran and Israel, and the Black Sea.

It tends to impact areas close to war zones as the technology is used to send suicide drones off-track.

Baltic countries have reported the issue for years, particularly since the war in Ukraine began in 2022.

Over the past six months, jamming has worsened around the Baltic Sea, Finnair pilot and Finnish Pilots Association Safety and Security Committee chair Lauri Soini said.

Soini said GPS jamming now occurs in an area extending from Poland across the Baltic states to the Swedish and Finnish coasts, also affecting lower altitudes and maritime traffic.

While politicians and German officials, opens new tab have pointed to Russia as the main culprit in the Baltic states, experts say Western militaries, including U.S. and British forces could be using some form of the technology in parts of the world.

why Is It a Problem for Airlines?
Most modern airliners have a variety of sensors and sources to determine their positioning, in addition to GPS, meaning they can fly if there is interference.

However, according to pilots and industry experts, airlines still rely primarily on GPS. If jamming or spoofing occurs, GPS might have to be switched off and cannot be reset for the remainder of the flight in many cases.

That can cause stress and delays for take-off and landing because certain procedures require GPS to function.

GPS navigation is also the only form of navigation for some private jets.

However, AirBaltic safety manager and flight captain Janis Kristops said the Tartu incident with Finnair was rare. Most major airports have a variety of navigation tools available if GPS isn't working, he said.

And given the diverse nature of wifi jamming and spoofing devices, it's difficult for the airline sector to come up with a sweeping technological solution that can mitigate the risk.

Instead, authorities are looking to train pilots to verify jamming and spoofing sooner.

Cut off Ring Camera Signals

An international burglary ring is suspected of using high-tech equipment to spy on expensive homes.

A search of the suspects' vehicles revealed cameras disguised with leaves.

Police say the burglary ring secretly installed hidden cameras outside homes so they could tell when the homeowners were away.

In another incident, police arrested two men who they say threw Wi-Fi jammers from their cars. Wi-Fi signal jammer are used to disrupt home security systems like Ring cameras.

The same person was arrested in both incidents.

All of the men are from Colombia. They are suspected of traveling to the U.S. on what authorities call "burglary tourism."

A couple has gone public with their security cameras saying they missed a burglar entering their home through a second-floor bedroom window because a Wi-Fi jammer disabled the security system.

"We learned from detectives that they installed Wi-Fi jammers that cut off the signal to the Ring cameras," Mytien Goldberg told Inside Edition.

"My cameras went offline around 9:30 p.m., and then they left the front of the house at 10:16 p.m.," Ala Tabatabai said.

The couple's home was vandalized when the thieves dragged a heavy safe that had been bolted to a closet out of the house.

"[Wi-Fi jammers] can disrupt any wireless system, including Wi-Fi, Bluetooth and radio frequencies," Officer Vahe Abramyan told Inside Edition. Abramyan said a single jammer could disrupt wireless systems for an entire neighborhood.

Federal law prohibits the sale and use of Wi-Fi jammers, but people buy them online and overseas.

Father Takes His Kids

A French father is facing jail time and a hefty fine for using a signal jammer to block his children from going online and affecting others in a nearby town.

Starting at midnight and ending at 3am every week, the French town of Messanges found their mobile phones and internet service no longer functioning.

A mobile operator reported the problem to the Agency Nationale des Frequencies (ANFR), the public agency responsible for managing the radio spectrum in France, and it was determined that someone was using a signal jammer to block radio frequencies in the town.

A signal jammer is a device that transmits radio waves at the same frequency as mobile devices to prevent them from connecting to cell towers and receiving legitimate signals.

A report from the ANFR explains that a technician tracked the jamming signal to a house in a neighboring town, where the homeowner admitted to buying the mobile jammers online and using it to force his teenage children offline.

“The reason is disturbingly simple: the jammer was installed by the head of the family in order to prevent his children from surfing the internet on their smartphones before bedtime! His children have literally become addicted to social networks and other apps, especially since the quarantine due to the Covid-19 pandemic,” the ANFR explains in the report.

“After consulting Internet forums, the father decided that a jammer was the best solution to stop these excesses!”

While the father’s intention was not to disrupt the internet for the entire town, using a jamming device is illegal in France and punishable by a fine of up to €30,000 and six months in prison.

Similarly, using a jammer in the United States is illegal and can result in prison and hefty fines.

“The use or sale of jammers in the United States may be subject to hefty fines, confiscation of illegal devices, and criminal sanctions including imprisonment,” the FCC’s enforcement alert on jamming explains.

Let Jails Use Cell Phone Jammer

Let Jails Use Cell Phone Jammer

Georgia's attorney general wants a federal agency to lift its ban on mobile signal jammer that bars state officials from using the devices to block contraband cell phones in jails and prisons.

The Federal Communications Commission currently bars cell phone "signal blocker" within prisons and jails, a prohibition Georgia Attorney General Chris Carr's office said extends to state and local governments. Carr made his request to reconsider the prohibition in a Tuesday letter to FCC Chairwoman Jessica Rosenworcel.

According to data included in the letter, contraband cell phones frequently make their way into jails and prisons, creating dangerous situations for inmates and correctional officers. Georgia officials confiscated 8,074 contraband cell phones in 2023 and 5,482 to date in 2024.

"The easiest way to protect the public from the harms caused by contraband cell phones is to allow for the use of cell phone jamming technology in prisons and jails, but the FCC continues to block our efforts," Carr said in a Tuesday statement.
"This outdated guidance limits legitimate law enforcement tools, presents dangerous conditions for correctional officers, and allows for the escalation of criminal networks both inside and outside prison walls," Carr added. "We're committed to combatting violent crime wherever it occurs, which is why we continue to call on the federal government to remove this substantial barrier to public safety."
In March, Georgia officials announced the results of "Operation Skyhawk," a months-long investigation into contraband at Georgia Department of Corrections facilities.

Authorities seized 273 contraband cell phones in facilities and arrested 150 suspects, including eight GDC employees who were immediately terminated. Bad actors used drones to help introduce contraband into the facilities.

"There are hundreds of examples from across the country of how a contraband cell phone in the hands of an inmate can be used as a deadly weapon and gives them the ability to continue their criminal enterprise," Georgia Department of Corrections Commissioner Tyrone Oliver said in a release.
"We are incensed by the length these individuals go to in continuing those activities and endangering the public," Oliver added. "As attempts to infiltrate our facilities with contraband cell phones evolve, access to jamming technology is paramount in our efforts to combat those attempts."
When asked whether he had a position on this request, a spokesperson for U.S. Sen. Jon Ossoff, D-Georgia, pointed to legislation he sponsored with U.S. Sen. Chuck Grassley, R-Iowa, to crack down on contraband in federal prisons.

In 2022, Ossoff led a 10-month-long bipartisan investigation into misconduct at U.S. Penitentiary Atlanta, now FCI Atlanta. The investigation's findings revealed the need to eliminate illegal cell phones in the facility.
