UK military jamming other nations' satellites to defend itself, BBC told

gorgoiler2 hours ago

Presumably when World War 3 kicks off the very first thing each adversary will do is to strike 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 hasn’t 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 it’s just economics — GPS is cool and cheap now, so why burn profit margin on developing an alternative?

PJDK1 hour ago

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.

I’m sure we’ll go back to beacons [1] here in the UK

Using 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 country’s defences and defeat the Spanish fleet before they were able to reach the English shore.

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.

Given the “Hybrid” attacks in Europe originating with Russia, the Houthi’s and Iran taking shots at shipping and the likelihood that certain countries are feeding Iran some of the intel… this is pretty understandable.

Russia makes whole regions inaccessible to GPS and it’s ultimately for the same underlying reason: soft kill systems and area denial scale better than kinetic options and are deniable.

It’s disappointing to see the majority of conversation here is moralizing and grandstanding rather than analysis.

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:

In that case you don't need to ground lasers, you just beam the data where you have unjammed communications with the cost of higher latency.

> Defence Secretary Wes Streeting said daily lives depend on satellites that power everyday technologies like mobile phones and banking apps, adding the loss of GPS would cost the UK economy £1.4bn a day.

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"

jameshart3 hours ago

In a largely cashless society like the UK, ‘banking apps’ are effectively people’s wallets. Knowing you got paid, being able to pay your rent, being able to pay for goods and services… seem like pretty everyday concerns.

b1122 hours ago

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.

jameshart2 hours ago

What does this have to do with the claim at hand which is ‘we need to keep our comms infrastructure secure because critical things like the primary way our population conducts economic transactions depend upon it’?

That you find the population’s 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.

b1121 hour ago

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.

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.

Rather the opposite. Peacetime is the only good opportunity to promote robustness and refuse toleration of vulnerable systems.

If you allow your banks and courts to be hacked freely by an adversary, then you can be manipulated into losing control of the escalation ladder.

autoexec2 hours ago

At the very least the idea of a population fearing for their future if an app doesn't work is frankly horrifying. In the case of banking apps there are already multiple, simple, well established, and widely supported alternatives to using the app available to them, but that should really be the case for anything actually critical an app provides.

All of that can be handed via your bank's website, ATMs, a credit card, or even (god forbid) writing a cheque.

jameshart3 hours ago

All of which (except the cheque, which we can ignore - nobody in the UK has a chequebook any more) depend on the same communication infrastructure that the app does.

autoexec3 hours ago

> All of which...depend on the same communication infrastructure that the app does.

That being the internet, which in the vast majority of cases doesn't depend on satellites either. Wifi, fiber, coax, and copper would continue to work just fine.

pixeljam2 hours ago

A lot of banks in the UK have mobile-app-exclusive features / services. I imagine this is because of security, but it also makes little sense. If you don't have a smartphone it is about 5x harder to do anything online-banking related here. I remember when I went camping a bit ago my phone died and I was unable to unfreeze my card.

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.

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.

mcintyre19942 hours ago

There are very few things that would cause banking apps to stop working while their websites continue to function.

Why does a banking app require GPS?

- 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.

autoexec2 hours ago

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!"

Melatonic2 hours ago

Pretty sure there's no way current satellites can even get close to the bandwidth of satellite links.

Also isn't GPS always wireless ?

nickweb3 hours ago

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 £5 for the window cleaner - more billions flowing every day).

O3marchnative3 hours ago

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.

I wouldn't be surprised if financial institutions use GPS for time keeping.

It's more accurate than getting it from a NTP pool.

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?

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.
