Presumably when World War 3 kicks off the very first thing each adversary will do is knock out their opponents satellites? These are like flying lightbulbs that shine down usefulness from above, so step one is to cut the lights.
Presumably-squared there is some kind of military backup to survive once the lights (GPS) go dark? Whatever that technology is, why hasnāt it proliferated into civilian life so that we all benefit from a resilient, non-GPS backup?
Perhaps the answer is that every tank has a 10lb inertial navigation gyro or some other thingy in it as a backup, and the platoon around it uses the tank as a moving trig point? In that case I can see it being infeasible to deploy that for civilians.
Perhaps-squared itās just economics ā GPS is cool and cheap now, so why burn profit margin on developing an alternative?
today at 10:23 PM
Knock out? no, best option is to have them all pre-hacked and send out spoofed data at the most desired times, especially if you knew what weapon systems were relying on them. Knocking out the satellites is like flipping the table in chess, you'd only do it if you were pretty sure you had no chance of winning because everyone else in the tournament won't like it. The duopoly-based cold war is over and those winner-take-all tactics were what drove USA policymakers to try so hard to get China to play on the world stage.
today at 8:02 PM
I think the general assumption is GPS is denied in most combat zones, it's constantly being jammed in and around Ukraine.
For most things the fallback is going to be everything we used to use. Maps, stellar navigation, inertial navigation that sort of thing.
Guided weapons wise, terrain mapping is pretty common for cruise missiles. Storm Shadow, for example uses GPS, terrain and inertial guidance systems. Trident uses inertia and stellar navigation.
As for why it hasn't proliferated into civilian use? Mostly it has its just the old things. You can perfectly well drive your car with a road map and sign posts. Pilots still train to use dead reckoning and beacons. Etc.
today at 9:52 PM
We also have visual navigation systems that can use satellite imagery to produce guidance packages. They will become increasingly less useful the longer the imagery goes without updates after a Kessler syndrome type event, though. Another strategy, which I believe the Ukrainians have been experimenting with, is scattering small radio beacons throughout the battlespace to provide a network of navigation aids.
In a true Kessler scenario where LEO is denied for an extended period of time, I expect a variation of that strategy is how we would replace GPS for most civilian use cases. Likely by using cell towers to triangulate, possibly enhanced with additional transmitters to improve accuracy and coverage. Pure cell tower triangulation would have much worse coverage than GPS, obviously especially in rural areas where cell service is often already poor, but also anywhere that getting a signal from multiple towers isn't easy or possible. Cell towers are never distant enough to use the relativity-based timing tricks GPS relies on, so multiple signals would be required to triangulate. We'd likely end up with substantially less precise positioning, maybe something more on the order of the 10-20m of error we used to see with GPS before the US stopped limiting civilian access to the deaccuratized version. Cell tower triangulation also obviously doesn't work for aviation or oceanic shipping, where trident-like inertial+stellar nav would probably be the only workable option.
today at 9:09 PM
Actually it hasn't proliferated into civilian use because the military industrial complex has captured pretty much anything with real accuracy.
I had an old colleague who in a previous life worked on an incredibly accurate positioning system that was effectively a brief case that knew where it was at all times. The story he told was the DoD made them an offer they couldn't refuse, and everything became secret. I'm pretty sure the company in question is still in business.
I'm not trying to say it's not legal but it might not exactly be legal?
today at 10:19 PM
> the military industrial complex has captured pretty much anything with real accuracy
Real accuracy is a matter of application. For mainstream civilian use the 20-30cm offered by Galileo/GPS is beyond real accuracy. It gets even better for specialized civilian use or with the aid of differential GNSS (low single digit cm). You'd have to think real hard for a reason to need better precision on a global scale especially if that involves any extra cost.
Can't say how much of a priority accurate positioning would be for civilians during an armed conflict.
today at 10:31 PM
> why hasnāt it proliferated into civilian life so that we all benefit from a resilient, non-GPS backup?
today at 8:27 PM
Right, in future conflicts between major countries the satellites will be first casualties. The US military is aware of this and still trains personnel on analog navigation techniques. Inertial navigation works well for some missions and research is underway on alternative technologies. Civil airliners can still navigate without GPS, although this may reduce safety and increase workload.
https://interestingengineering.com/military/us-military-nail...
We're also going to need a prompt launch capability to replace attrition losses. There should be warehouses full of spare navigation, reconnaissance, and communications satellites ready to mount on a reusable booster and launch within hours. Concerns have been raised over a "Kessler syndrome" due to orbital debris but in lower orbits with significant atmospheric drag this won't be a serious problem.
today at 9:31 PM
Reminds me of in the Avengers - SHIELD couldn't navigate the helicarrier, and Nick Fury said "Is the sun setting? Then put it on our left!"
today at 9:25 PM
IIRC, the Navy stopped teaching officers traditional ship navigation methods for awhile, until the series of incredibly stupid incidents drew attention to the lack of basic navigation and piloting skills, then curriculums were partly reverted. Not sure if things have improved much; probably too early to tell.
I doubt officers or crew would ever have to resort to a sextant, but that's besides the point. It's the type of thing that's integral to learning navigation theory and building tacit knowledge that's fundamental to the job.

Iām sure weāll go back to beacons [1] here in the UK
āUsing fire to signify a message is thousands of years old. The earliest use of beacons in the UK dates back to the medieval period, primarily as a means of communication to warn of impending invasions or other dangers. Positioned on hilltops and along coastlines, these beacons were part of an early warning system signalling the presence of a threat, such as an approaching enemy fleet.
One of the most famous early examples is the network of beacons used during the Spanish Armada in 1588. As around 150 Spanish battleships approached, beacons were lit along the southern coast of England, from Cornwall to London. As a result of this rudimentary but effective system Lord Francis Drake had the time to mobilise the countryās defences and defeat the Spanish fleet before they were able to reach the English shore.ā

Pretty sure the Spanish Armada was <150 total ships, of which only a small subset would be the big galleon things. (And then my knowledge hits a wall, idk what the difference between a galleon and ship-of-the-line/battleship is)
I'm not sure how much to trust the rest of that website.

The US military has been funding plenty of projects related to what it calls Alt-PNT, or "alternative position, navigation, and timing" systems. I imagine other nations have invested in this as well.
Which systems are actually getting deployed, and in what pieces of equipment? No idea, I imagine that's super duper classified.
today at 8:44 PM
There's technology now that matches local satellite/aerial images against the imagery that a drone or cruise missile sees to replace the GPS chip.
For fairly obvious reasons, militaries that have it would rather it stay in their hands, for fear of creating a non-state peer competitor that can do cheap long-range strikes on strategic targets.
It's fairly likely it'll fall into private hands anyway though, because anyone who can afford the prices for commercial satellite imagery could build such a thing.
today at 8:30 PM
> Whatever that technology is, why hasnāt it proliferated into civilian life so that we all benefit from a resilient, non-GPS backup?
Once a stealth technology is integrated into civilian life, it's no longer stealth, and you lose the element of surprise if you have to use it in warfare. If somebody _does_ feel they have a clever secret work-around, the incentive is pretty high to keep it a secret.

There's a bunch of stuff for using terrain to figure out where you are [1], generally used for missiles and planes though, not sure if works well from a ground perspective.
On the ground, you might be able to use the broadcast positioning system: more or less GPS but instead of satellites, the broadcast signal comes from existing TV towers... TV towers may well be targetted at some point in a war, but there's likely more valuable targets at the beginning of a war.

GPS has relatively few satellites... but if in doubt, I think Starlink with its absurdly large fleet of satellites can be used as an alternative. Maybe not at a precision level good enough for precision farming, but good enough to roughly guide troops to where they need to go.
Modern cruise missiles and stuff like Storm Shadow, Taurus etc. already rely on sensor fusion - GPS, inertial navigation, radar, optics and probably a ton more to always keep track of the position.
Assuming Starlink is a no-show for whatever reason, airliners and ships will have to revert back to stationary navigation aids aka your good old light towers and radio beacons.

I works assume if/when something really kicks off the starlink and starshield networks would be high priority targets.

That was the McGuffin for the 1963 book "Ice Station Zebra" (and the 1968 film adaptation). A satellite with pictures of every missile launch site in the US malfunctions and is knocked off its planned orbit that would overfly the Soviet Union, so the race is on to figure out where they would drop the film and prevent them from recovering it.
The story was based on a real-life incident in 1959:

Oh no! Not our precious banking apps! What a weird thing to call out specifically. It's also kind of strange to talk at such length about how critical satellites have become to people's lives, national economy, emergency services, and people's "daily freedoms", only to conclude with "So now we're using ground-based systems to take out the satellites other countries depend on for all of those things"
today at 6:34 PM
In a largely cashless society like the UK, ābanking appsā are effectively peopleās wallets. Knowing you got paid, being able to pay your rent, being able to pay for goods and servicesā¦ seem like pretty everyday concerns.
today at 7:25 PM
If you're bored, have Claude pull apart your APK and do a privacy report.
Your banking app is almost certainly using a company like (horrible and evil) Yodlee, which is given data by your banking app under the guise of "organizing your transactions into categories". Yodlee then quickly de-anonymizes it, by the identifiers which are identical and given to firebase, and various other orgs. Yodlee has been caught doing this before, and they still operate.
Lots of other companies do this, so if your banking app has any callbacks to anywhere but the bank itself, it's nothing but trouble.
After deanoymoization, such data is of course sold to everyone, including intelligence agencies, domestic and foreign.
today at 7:29 PM
What does this have to do with the claim at hand which is āwe need to keep our comms infrastructure secure because critical things like the primary way our population conducts economic transactions depend upon itā?
That you find the populationās choice to use such mechanisms questionable, or that you think it is foolhardy to do so, does nothing to disobligate the government from trying to keep that infrastructure up and running.
today at 8:03 PM
The point more is, this is one primary mechanism to spy on the populous. Primarily via 5-eyes, which means Americans are buying this data to spy on UK citizens.
today at 7:43 PM
I think they are pointing out it's an oxymoron. There's nothing to secure if the service itself is insecure and leaking..
today at 7:50 PM
It's classic what-aboutism though. Availability is part of security and that's what seems to be considered here. It's also the more immediate concern. Yes, the software supply chain and where your data goes has high potential for compromise. But I'm not actually seeing rampant fraud in my accounts or data leaks from my bank very often.
today at 8:04 PM
High potential for compromise? No, the point is that every single transaction you make is being sold on the open market, that's the problem. Using cash prevents this. Using debit cards, credit cards, banking apps ensures this.
The banks provide the data anonymized, but then provide means to de-anonymize it.
today at 8:14 PM
You are discussing concerns that are completely orthogonal to the thread. The availability of digital banking was the concern. Not end to end privacy.
today at 7:43 PM
So yeah that sucks, but... what does that have to do with the concerns being discussed here?
Digital banking in some form is pretty unavoidable for me unless I want a "live in the woods" type lifestyle and all the consequences of it. And I don't even live in the UK where they've embraced it more. My mortgage was sold to a very distant company and we've had mail problems. My dog recently needed middle of the night surgery and they wouldn't start without payment that exceeded normal cash reserves + daily.
Yes, all these things suck, but shooting digital banking in the knee without a solution to all that isn't helpful.
today at 7:51 PM
Digital banking might be unavoidable but what did your app do that you couldn't have possibly done via your banks website?
today at 7:56 PM
You know, I didn't rush my laptop to the vet with me. If you're going to argue with the "mobile phones and banking app" line to this extent, I will freely admit: yes, if you want to be a Luddite, satellites are indeed unnecessary. You are absolutely right. But still not convincing me that's a weird thing for them call out here.
today at 8:29 PM
today at 8:12 PM
Realistically, paying your mortgage isn't giving any data a credit pull wouldn't. It's not a secret you live where you do. And one off emergencies aren't the problem.
It's foregoing cash for every single thing you do. That, combined with the telco selling data, Google linking that data to the number, and apps such as your banking app working in this same ecosystem, and companies such as Yodlee, your profile has a minute by minute location, plus what you spend and where.
It lets intelligence agencies, buying this data, create links between people. Who you know. Who you talk to. Where you go. What your hobbies are.
This gives the power of manipulation, for knowing who you are in the real world, combined with what you do online, means they know you better than you know yourself. And that's quite important, if you want to manipulate opinion.
All this may not matter to you, and if so, that's fine.
But this data is, quite frankly, what gives the Americans the power they have. The Americans aren't mighty due to guns, and weapons, and an army. They are mighty because of information.
Information is how you send a mere 40 dudes to kidnap the President and his wife from Venezuela. Information is how drone strikes perform targetted attacks. Information is how you manipulate elections in foreign countries. It's the sort of power that means you don't even have to fire a shot, to overthrow a government.
This information is what modern banking, and its apps, and companies such as Yodlee give to the Americans.
And as a Canadian, with the Americans blathering on about 51st state this and that, I am perhaps over sensitive to this fact. Because the last thing we need, is to give Americans power over us.
Any power.
Even the tiniest bit.
And information? Is more powerful than anything else they have.

At the very least the idea of a population fearing for their future if an app doesn't work is frankly horrifying.

On a couple of occasions, I went with him to get cash by driving to a bank branch, writing a check, and having the teller cash it for him. It took months to convince him that he absolutely needed a debit card when people were constantly asking if they could use Venmo/CashApp/etc to pay for products.
So we're still in a transitional stage where some people are still stuck on using checks.

At least I see them being used less often in stores. Also how on earth was he paying $200 for checks? You can get them for < $15. Here's a book with a fish on it, and a ledger, and a cover for under $25 https://www.checks.com/p/856/wonders-of-the-sea-checks
today at 9:00 PM
Man, don't get me started. However, business accounts are more expensive than regular accounts. Also, why are you surprised that a bank has found a way to charge more fees?
today at 8:56 PM
Check processing I think, not writing them
today at 9:20 PM
No, the ~$200 fee was for the book ledger and blank checks. I have no idea what kind of monthly fees the bank was charging for the account. He was also getting raked over the coals on his merchant account to process credit cards because it was deemed a high risk business so most reputable places would not accept the business.
today at 7:04 PM
There are several companies in the UK offering cheque cashing services so I presume somebody there is getting them.
today at 7:01 PM
No
today at 7:04 PM
Or checks?
today at 7:24 PM
Certainly not spelt (or spelled) like that.
today at 10:25 PM
If banking went down we'd have a hell of a time. It's not like I keep 6 months rent in cash on me.
today at 6:32 PM
Why is it strange? Millions of people use banking apps daily to make transactions essential to their lives and businesses.
today at 6:36 PM
It's also a favourite stat of the UK space industry that a large percentage of UK GDP is vaguely linked to space in some way, and "some of your financial transactions touch a satellite uplink or require location data" is one of the more tangible non-obvious ones.
today at 6:38 PM
Those apps can all be replaced by a website, and most banks already have those websites, which means if all the banking apps on earth stopped working right now the solution wouldn't involve anything more complicated than stabbing your finger at different icon on your phone and typing the name of your bank into a search engine.
today at 7:29 PM
There are very few things that would cause banking apps to stop working while their websites continue to function.
today at 8:11 PM
Presumably it'd be the loss of mobile service and/or GPS that would cause every banking app in the UK to fail, but I'm a bit skeptical that either one of those is a strict requirement.
today at 6:43 PM
not being funny - if the internet goes out how does a website make this better?
today at 6:45 PM
> not being funny - if the internet goes out how does a website make this better?
The internet for most people doesn't depend on banking apps, or satellites. Wifi would still work great. If the internet actually did go out everywhere, how would an app help you?
today at 6:50 PM
The UK is an island nation that's reliant on undersea cables. If those cables are cut (which is something that Russia seems to threaten) your only fallback is satellite connectivity - so protecting that connectivity is pretty key to ensuring e.g people can access their money.
I would guess that was how Wes Streeting was briefed (and then completely bungled in public comms).
today at 6:59 PM
ideally British banks would have their infrastructure located in Britain and therefore would not rely on undersea cables
today at 7:05 PM
Monzo (a major UK bank) use AWS and GCP. Hopefully their DCs don't fail in some way when losing access to the outside world but I would hazard a guess something goes wrong.

Thats the point, the reasons the apps dont work would be the same reason the websites dont work. They are not work around, I think apps is just mentioned because 90% of people use them over the website
today at 6:52 PM
today at 6:55 PM
Banking apps don't depend on satellites, either.
today at 7:42 PM
I think this comment is the tech equivalent of "if they can't eat bread, let them eat cake"
today at 7:48 PM
That would imply that somehow a bank's website was a less accessible option than the app is, when the app is dependent on a mobile device as opposed to the website which is avilable on virtually any device with a browser including the same mobile device the app is installed on.
today at 6:42 PM
Thatās beyond about 90% of the population.
today at 6:41 PM
It's not and it's also not uniquely a British thing either. Most of my friends and myself use our phones as wallets, in the US. The only time I use my physical cards is to pull cash from the ATM, ha.
today at 6:45 PM
In my household, we refer to coins as āparking tokensā.
today at 6:59 PM
I should start calling my jar of quarters the "laundry tokens" haha.
today at 6:34 PM
Why does a banking app require GPS?
today at 6:48 PM
- The UK is an island nation
- In event of all undersea cables being cut (which is a serious threat from Russia), satellite internet is your only option to have traffic leave the UK
- Unfortunately most major banks in the UK have very fragile infra that relies on foreign cloud hosts e.g AWS or Azure, which could well fall over in unexpected ways if the UK was cut off from the world
To be clear I disagree with Wes Streeting on a lot of this but the UK is in a uniquely precarious spot when it comes to how much is reliant on internet access.
today at 7:29 PM
Those cloud hosts like AWS have infrastructure in the UK and a UK bank's data should already be there for performance reasons (see https://docs.aws.amazon.com/global-infrastructure/latest/reg...).
I can't promise that amazon has taken into account the possibility of not being able to phone home to the US, but I would hope an undersea cable cut is something they'd have already given serious consideration to. Cuts do happen every so often. Scandinavia in particular has seen several disruptions because of cable cuts.
Either way, it's a bit of leap to go from "We need to jam other countries satellites to protect your banking app" to "but what if the UK lost every satellite, and every undersea cable was cut, and all the local data centers and internet infrastructure in the UK stopped working!"
today at 7:40 PM
Pretty sure there's no way current satellites can even get close to the bandwidth of satellite links.
Also isn't GPS always wireless ?
today at 6:36 PM
GPS relies on very very accurate timing. I would wager that the timing side of GPS is used more than the positioning side - but I have no way of confirming that.
Accurate timing is needed for banks accepting/sending payments (not just Ā£5 for the window cleaner - more billions flowing every day).
today at 6:42 PM
That makes the issue worse as the actual app/device likely just relies on querying some NTP pool for accurate time. Then that would mean the actual stratum 1 servers are not working right.
today at 6:43 PM
I wouldn't be surprised if financial institutions use GPS for time keeping.
It's more accurate than getting it from a NTP pool.

It doesn't. They're making shit up.
today at 7:02 PM
Just read the article and the conclusion was that they're using ground based systems to disrupt other countries satellites that are targeting the UK, not the one's that those countries depend on for their own internal services.
today at 7:33 PM
I guess the question is what does "targeting the UK" look like exactly? Flying over it? Flying over it with a camera?
They call out "tracking the movement of the UK's nuclear armed submarines or other sensitive military operations, such as those involving special forces." but that could mean they jam military satellites that are doing that, or it could mean they're jamming satellites that might be capable of doing that. What would that mean for something like a weather satellite?
today at 7:37 PM
Look, I'm a big believer in the importance of cash as an option in our society and the importance of keeping a supply on-hand for emergencies, but my mortgage company, employer, and a lot of other financial concerns are hours away from me, so yeah - my banking app is pretty fucking important to my daily life, and I don't even live in the UK where they have embraced digital banking even more.
It's light on the details of what they're disrupting and how, but there is zero suggestion in the article that they are disrupting digital banking, the Internet, or consumer services at all for for other countries.
today at 7:45 PM
Is there something on your banking app that you couldn't do by browsing to your banks website?
today at 10:31 PM
I work for a UK fintech that is bank-adjacent, the backend for the apps and the website are the same.
today at 7:53 PM
Asbolutely. Tap to pay options, and the better ones have stopped pushing SMS for 2FA and they will prefer their own apps over third-party ones. JPMC, Capital One and E-Trade (now Morgan Stanley) definitely all do this.
today at 8:03 PM
Tap to pay is also doable with a credit/debit card, but paying via phone is a legitimately useful feature although also not remotely critical or something that would be world ending if it were disrupted.

The UK's largest export is banking (i.e. money laundering).
today at 9:06 PM
Hate to break this to you, but not all banking is money laundering. Not even all banking in the UK. Not even all banking exported from the UK.
today at 9:22 PM
You don't need another country to export your ordinary banking.

It should be standard practice to use radio jammers and dazzling lasers against every non-allied foreign satellite that passes over our territory, or any of our military bases or warships. Why give them a free look?
today at 9:03 PM
When I moved to the west coast, I was looking at the history and how cities like Burbank lived under a tarp cover that when viewed from the air looked nothing like the city/airport that they were covering. The fear of another Pearl Harbor like attack was that great. Plus, all of that cool shade while denying the enemy!!
today at 6:58 PM
Because that is one of the methods used to verify that everyone is complying with treaties, such as nuclear non-proliferation treaties.
today at 7:13 PM
Unfortunately it's a little too late for that, those treaties are effectively dead anyway. Not a good situation but that is our reality.
today at 8:26 PM
It's a waste of money for no benefit to anyone but the military and its industrial parasites?
