Planes Are Having Their Gps Hacked. Could New Clocks Keep Them Safe?

As a Ryanair formation from London approached Vilnius, Lithuania, connected 17 January, its descent was abruptly aborted. Just minutes from rubbing down, nan aircraft's basal Global Positioning System (GPS) suffered an unexplained interference, triggering an emergency diversion.

The Boeing 737 MAX 8-200 had already descended to astir 850ft (259m) erstwhile nan disruption occurred. Instead of landing, nan level was forced to climb backmost into nan entity and divert astir 400km (250 miles) southbound to Warsaw, Poland. Lithuanian aerial authorities later confirmed nan craft had been affected by "GPS awesome interference".

This was not an isolated incident. Over nan past 3 months of 2024, much than 800 cases of GPS interference were recorded successful Lithuanian airspace. Estonia and Finland person besides raised concerns, accusing Russia of deploying exertion to jam outer navigation signals adjacent Nato's eastbound flank – though nan state has denied that. Last March nan past Defence Secretary, Grant Shapps, was connected a level that had its GPS awesome jammed while flying adjacent to Russian territory.

The threat of GPS jamming extends beyond aviation. Without GPS, our lives would grind to a halt: successful 2017, a authorities study stated that systematic GPS jamming could bring nan UK's financial, energy and communications systems to a standstill.

To pinpoint our nonstop location, we request to cognize nan nonstop time. GPS useful by users receiving signals from aggregate satellites. The magnitude of clip it takes each awesome to scope a instrumentality is utilized to find precisely wherever connected Earth we are.

Very ample atomic clocks pass straight pinch nan satellites, allowing them to cognize nan clip to wrong 100 billionths of a second, and this precision timing is cardinal to a assortment of economical activities astir nan world, including connection systems, electrical powerfulness grids, and financial networks.

The imaginable costs of losing GPS has been put astatine £1.4bn each time – nary wonderment GPS jamming is connected nan government's nationalist consequence registry arsenic 1 of nan UK's top threats.

With this successful mind, a group of British scientists – dubbed nan "Time Lords" – has been asked to travel up pinch a solution.

The scheme is simple: to create a much unafraid replacement to GPS by enabling nan portable usage of caller atomic clocks, alternatively than relying connected signals from satellites successful abstraction that tin beryllium jammed. But its execution is fiendishly difficult: to harness nan powerfulness of nan atom, create a caller type of clock, and moreover alteration nan measurement we measurement clip itself – each wrong a fewer years.

In caller months, nan UK authorities has group up investigation initiatives to tackle nan threat of GPS jamming. But turning prototypes into robust devices that could 1 time beryllium incorporated into our phones is an tremendous undertaking – and nan request for nan caller exertion is getting ever much urgent.

The situation tin beryllium compared to nan invention of a portable timepiece for marine navigation by John Harrison successful nan 18th Century, which solved nan alleged longitude problem, allowing a caller era of waste and acquisition and a aureate property of exploration.

Three 100 years on, researchers are erstwhile again racing to cleanable a caller timepiece to lick nan GPS problem – and nan effect could beryllium astatine slightest arsenic transformative.

"History shows that each clip we person an betterment successful nan expertise to measurement time, caller applications travel to make things imaginable that group didn't dream of before," says Dr Helen Margolis, caput intelligence (time and frequency) of nan UK's timing laboratories astatine nan National Physical Laboratory (NPL) successful south-west London.

In 1967, nan world's timekeepers, an intergovernmental assemblage called nan General Conference connected Weights and Measures, agreed to specify clip utilizing atomic clocks, alternatively than by nan Earth's rotation.

The move transformed our world conscionable arsenic radically arsenic Harrison's clock, laying nan instauration for GPS and akin space-based systems. These provided precise timekeeping from atomic clocks connected satellites, which allowed accelerated and immense volumes of communications, computation, and transactions to beryllium carried retired everyplace successful nan world adjacent instantaneously, arsenic good arsenic much precise navigation.

The hunt for a caller portable replacement to GPS involves a section called quantum technologies, uncovering ways to manipulate atoms. Much of nan buzz astir nan taxable successful caller years has been astir nan improvement of powerful quantum computers which, nan communicative goes, will make our fastest supercomputers look for illustration abacuses by comparison.

But a quieter gyration to amended navigation and measurement of clip has flown nether nan radar, and it is successful this section that quantum exertion is group to make its earliest impact, according to Prof Douglas Paul of nan UK Hub for Quantum Enabled Position Navigation and Timing (QEPNT), which was group up past December by nan authorities to create these caller devices.

"We are expecting to spot immoderate benignant of navigation strategy wrong 2 to 5 years successful nan marketplace," he says. "So, immoderate of these technologies are already rather advanced."

Prof Paul and his quantum scientists are moving pinch Dr Margolis and her chap researchers astatine NPL, who person been fixed nan "Time Lords" nickname by different horologists. In 1955, nan NPL invented nan first atomic timepiece of nan benignant that is utilized today, based connected nan wave of radiation from an atom of nan constituent caesium.

GPS and different outer navigation systems reset their ain clocks by rubbing guidelines pinch these much meticulous clocks connected nan ground. For nan replacement to GPS, nan scientists will request a caller type of atomic timepiece that tin yet beryllium miniaturised and robust capable to activity successful mundane situations, alternatively than nan cautiously controlled conditions wrong a lab.

The NPL researchers are perfecting a alleged optical timepiece to execute this, which is 100 times much meticulous than nan astir meticulous caesium clocks utilized today. It looks arsenic if it mightiness beryllium portion of Dr Who's Tardis and is stimulated pinch laser ray alternatively than microwaves.

When optical clocks return complete from caesium ones arsenic nan timepieces that find Universal Coordinated Time (UTC), nan measurement nan transition of clip is defined will besides person to change, according to Dr Margolis.

"The world organization has drawn up a roadworthy representation for nan redefinition of nan second," she tells BBC News.

The NPL's contiguous dream is to person a nationalist web by 2030, connecting 4 atomic clocks crossed nan UK that businesses tin plug into for unafraid meticulous timekeeping and for processing caller innovative applications that harness ultra-fast time.

Eventually, captious systems successful nan UK successful finance, telecommunications, energy, utilities and nationalist information could move complete – though that would return longer. "To person everything is astatine slightest a decade away, and astir apt importantly longer," says Prof Paul.

Yet nan stakes are high, and nan replacement this caller exertion offers is significant. "The US Department of Defence mightiness determine to extremity supporting GPS, it could beryllium taken retired successful a conflict aliases by an accident," he says. "There is nary guarantee GPS … will ever beryllium available. With each nan jamming and spoofing [where a criminal gives a mendacious awesome pinch an incorrect clip and location], you cannot ever guarantee you person an assured signal, truthful if you cannot get aliases spot nan accusation past group will extremity utilizing it."

While this type of investigation is taking spot astir nan world, it's being led by nan UK. When an craft pinch nan exertion connected committee carried retired a trial formation successful May 2024, nan past subject curate Andrew Griffith described it arsenic "further impervious of nan UK arsenic 1 of nan world leaders connected quantum". According to nan government, it was nan first trial of this type of exertion successful nan UK connected an craft successful flight, and "the first specified formation worldwide that has been publically acknowledged".

By carrying a group of atoms cooled to -273C connected nan level itself, alternatively than relying connected an outer signal, nan exertion can't beryllium interfered pinch by jamming.

But nan problem is that nan instrumentality is still excessively ample to beryllium utilized routinely connected planes.

Henry White, portion of nan squad from BAE Systems that worked connected nan trial flight, told BBC News that he thought nan first exertion could beryllium aboard ships, "where there's a spot much space".

Quantum clocks, gyroscopes and accelerometers are large, bulky and incredibly expensive, pinch an meticulous quantum timepiece costing astir £100,000. Yet subject investigation is allowing nan creation of smaller, amended and cheaper systems.

GPS jamming is causing problems for nan British subject successful conflict zones specified arsenic Ukraine. One of nan main challenges faced by scientists astatine nan government's Defence, Science and Technology Laboratory (DSTL) is making nan delicate exertion activity not conscionable successful nan existent world, which successful nan Navy's lawsuit is often successful very choppy seas, but besides successful nan harshest of environments; nan battlefield, according to a lead interrogator astatine nan DSTL, who has to stay anonymous for information reasons.

"We are harnessing atoms," she points out.

"You person vibrations, you person unit changes, you person somesthesia changes, and you person environments which person each of these different variables going connected while you are trying to manipulate nan properties of light. So, it's precision that is needed".

The eventual purpose for immoderate of those moving connected this caller exertion is for each of america to person nan balanced of our ain individual GPS strategy incorporated into our phones.

This would comprise a miniaturised optical timepiece arsenic good arsenic a mini gyroscope, truthful we cognize which guidance we are going in, and a instrumentality called an accelerometer, which will show america really accelerated we are going.

QEPNT has been group up by nan authorities to shrink nan devices connected to a chip, making them robust capable for mundane life and affordable for everyone.

That process isn't going to hap soon, though. "This is galore decades distant from happening for each captious nationalist infrastructure crossed nan UK," says Prof Paul.

Quantum timepiece researchers are facing precisely nan aforesaid problems knowledgeable by John Harrison erstwhile he was processing his portable marine timepiece successful nan 18th Century. Mr Harrison had to build a timepiece whose timekeeping was not affected by changes successful temperature, unit aliases humidity, and was capable to usability successful a perpetually moving vessel – his top trouble was to make it small.

But it turned retired that his trouble was besides nan way to his solution. The smaller he made his clocks, nan much robust he recovered they were astatine sea.

"Harrison recovered that it was it easier to isolate them from each those outer influences," says different DSTL scientist.

"As was nan lawsuit 300 years ago, arsenic we make these systems smaller, it will go easier to power nan situation astir them and isolate them from nan effects of vibration, temperature, pressure, and humidity."

Prominent 18th-Century scientists, including Sir Isaac Newton, thought that navigation pinch marine clocks was impossible. But yet Mr Harrison, a elemental clockmaker and carpenter, proved his much illustrious colleagues wrong.

Bringing prototype optical clocks first into nan battlefield and past yet into mundane life is conscionable arsenic challenging. Will nan scientists moving connected nan problem beryllium capable to find solutions accelerated enough?

One time we mightiness person them successful our pockets, but nan much urgent purpose is to get them successful a authorities wherever we tin safely fly, arsenic incidents of GPS jamming connected planes and captious machine systems increase. The Time Lords and quantum scientists dream to proceed nan humble clockmaker's bequest – transforming nan measurement of time, and protecting nan UK's captious systems from GPS attack.
