  • I mean, they can, but they literally have a .gov webpage dedicated to Bill Clinton's 2000 act of ending SA and how it will not be changed. So they could, but they'd be renaging on a promise made to the civilian and commercial public. Which in the current climate is entirely possible.

    So yes, a receiver could be altered based on a predetermined hard coding, but I think something like that - Geo based hard coding - would be available knowledge, maybe not widely or publicly, but available knowledge.

  • https://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/gnss/faq/gps/

    "It is not the intent of the U.S. to ever use SA again. To ensure that potential adversaries to do not use GPS, the military is dedicated to the development and deployment of regional denial capabilities in lieu of global degradation through SA"

  • Just read that Galileo has selective availability but there is an agreement between member countries that it should only be used in the event of armed conflict.

    So as long as Brexit doesn't get all shooty, we should be ok ;)

  • You can literally see the packets of data that the receiver receives. You, me, the guy who runs Mamnick, anybody who owns a receiver and a computer, can see the data.

    So unless each receiver is filtering out confidential information, which means every single device manufacturer is in on the system, that's just not possible.

  • Well it'll be no big loss unless we also start a war with USA and Russia.

  • You're missing the point.

    If the GPS signal from the x number of sattelites that you have a fix with says "civilian_active=false" (or code to that effect) then your receiver will not work.

    Anyway, it really doesn't matter, because it is vanishingly unlikely that this is done by country code.

  • I totally get that, but we were talking about country specific, which GPS doesn't appear to have, but Galileo apparently does.

  • Under free movement of goods all GPS sold into the UK could have been sold from or into any EU state. How do they know which ones to turn off?

  • The one's that guide their owners to carveries where Gammon is high on the menu?

  • Encrypt the Galileo signal, with the decryption key-stream "you gammon faced cunt".

  • putting a huge tinfoil hat all the way over the UK

    Sounds good - we need a referendum on it

  • Why is it so hard to discover who these '40 MPs' are who the media are going on about derailing May's Brexit plan? If the press and the leading loonies know who they are, why don't we?

    The point of SA is that every GPS receiver is receiving information that is partially obscured. The lower order bits of the timestamps from the satellites (which form the basis of the trilateration) are encrypted, so they are effectively random noise. If you know the encryption key (which changes daily in some implementations) then you get the accurate timestamps and therefore the most accurate location. If you can't decrypt the lower order bits of the timestamps then they're random noise which leads to accuracies of 50m+ when used.

    Anyone can see the data, sure, but only those with the encryption key(s) get the completely accurate data.

    the military is dedicated to the development and deployment of regional denial capabilities in lieu of global degradation through SA

    The signals from the satellites are piss weak. It would be easy for the EU to pump out conflicting signals towards the UK which are enough to introduce a ~50m inaccuracy in GPS measurements (akin to what SA would do globally). And there would be close to fuck all that the UK could do about it apart from whine. This is what the US mean by "regional denial capabilities"; it's not jamming, but spoofing.

    Anyway, it's simply not a problem as I don't think any UK Sat Navs are designed to run solely on Galileo. If we get to the point that Russia turn off access to GLONASS and the US restrict access to GPS (i.e. what was NAVSTAR) and we can't get access to India's system, or China's, or Japan's, then we are already properly in the shit. We'll be long on the way towards mutual assured destruction by that point so being able to direct an Uber to your front door will be the least of your problems.

    DUP threatening to bring down government.
    Launch your orange popcorn engines...once again.

  • ^ Cake, you say?

    DUP kicking off because they still feel betrayed over the Anglo Irish agreement Thatcher signed...

  • Hahaha amazing!

  • huge if true tho.

  • McCausland is of the belief that the people of the British Isles are descended from the lost tribes of Israel,[17] and has addressed events organised by the British-Israel-World Federation.[18][19]

    The DUP...in before it was hip ;)

  • That's very well done. Perhaps so much so that it makes both May and Johnson seem kinda ok rather than leaving the viewer utterly repulsed...

  • It is going to be no-deal, unless May resigns.
