    Clickbait from 404 Media? Surely not!

    The part they kept out of the headline:

    > for use in distributing the keys for accessing the military GPS signals

    It’s common knowledge that the military has access to a separate, encrypted, higher-precision GPS signal. “Numbers station” implies that they’re distributing unrelated encrypted information, but they’re not; it’s not surprising that GPS signals would be used to deliver information related to GPS, even if only military receivers have any use for it!

    "Numbers station" is a weird analogy, because the idea of a numbers station was to broadcast messages to undercover operatives in a way that can be received using unmodified (and therefore non-suspicious) household radio receivers.

    Here, it appears to be a rekeying system for specialized military gear.

      I think it's simply because of using a public channel for encrypted communication.

        Technically all RF communications are "public." You have to use encryption if you want security.

          Would point to point laser seem like it's RF and not readily snooped without detection?

            Unless you are in a vacuum, a laser that can reach a useful distance can be observed due to atmospheric scattering.

      Yeah its not a number station at all.

      • Analemma_ 29 minutes ago

        I disagree? The point of a numbers station is that it broadcasts in the clear and anyone with a receiver can get it, but only people with the appropriate decryption key can make any use of it. Since it's broadcasting all the time, there's no need for steganography or covert transmission. That's exactly what a numbers station is.

        Where the article loses me is the implication that this is somehow sinister or beyond the pale: it's just piggybacking on a global transmitter network that exists anyway, why not?

          Its all comes down to what we buy as the definition for a number station. For me a number station needs sends a message to be a number station, not a key.

            We don't know that it's a key that's being sent. For all we know, it could be just random data. Obviously it's most likely not random data, but ciphertext. Either way, we have no idea what the message is.

    People are complaining about a clickbaity title but it's a fascinating article I am not sure most would read otherwise

    What's interesting to me is how out of date US GPS system is compared to China's BeiDou

    and while most US GPS receivers will use Russia's GLONOSS, China's BeiDou is blocked

    GPS was always a dual use system. This is very detailed and specific, but not interesting or surprising. Research has been study GPS signal data, found parts that are encrypted and he doesn’t understand. The end. Article seems only intended to generate an emotional response of “how dare they use GPS for war, man!”

      > GPS was always a dual use system

      It wasn't. It was going to be a military-only system, until KAL007 presented the obvious life-saving civilian case.

      But yes, the title of this article might as well read "Satellite system developed for military use is being used for a military purpose."

      • eagerpace 31 minutes ago

        Even better, thanks for clarifying. It’s that kind of omission from the article that makes the rest of it hard to swallow. Even if it is technically correct. Which is sadly the case for most “journalism” these days.

      It’s not surprising, but I find it interesting.

    Slightly related the latest Veritasium Video: Something is jamming GPS over Europe.

      TLDW: Russia is jamming GPS and GNSS over Europe, purposefully, using a constellation of military satellites.

      Theory is that Russia is constantly practicing to totally disrupt GPS and GNSS (and the Chinese system) across all of Europe.

    best zero day exploit ever

    • gruez 34 minutes ago

      That's not what a 0day exploit is. It doesn't allow you to take over arbitrary GPS receivers, for instance.
