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?
So, who's the UK actually attacking?
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"
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.
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.
Also, cool username =)
- 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.
Accurate timing is needed for banks accepting/sending payments (not just £5 for the window cleaner - more billions flowing every day).
Some bank apps can block this access or request more validation
I have no idea what that quote is trying to say...
or a whole new technology invented other than radio waves for data transmission
are any satellites using laser downlink yet or is line-of-sight too temperamental with weather and planes?

The story was based on a real-life incident in 1959:

They'd drop their film back down to earth.
but seriously, the first spy satellites used to drop film rolls and they had a crazy way for the military to track and catch them via planes

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.
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.
