alt Hacker NewsThis is an interesting article. It has a very strong AI accent.
I really wish I could tell how real it is. When some part of it I can tell is AI slop, how much of it is AI slop? Inside GNSS has always been a marketing rag with sometimes some interesting articles.
The author is a security researcher, so maybe poking at GPS bits makes sense, but talking about floating point bit depth? There's too much slop for me to figure out if there's anything of real interest or if this is just a hallucination.
Edit. After reading more carefully this is 100% AI slop. Inside GNSS published Steven Murdoch's chat gpt session. Maybe some data was transmitted? The only way you'll actually know is to redo the research your self. There are many fabrications / confabulations that clearly happen with AI in the text.

I've worked with the guy credited in the article before, so I'll vouch for his general credibility and the underlying information likely being solid: there's good evidence for this field being some kind of encrypted data stream, probably key distribution, and the behaviour has changed over time. But the breathless LLM-tone really did make it hard to read.
So much AI. I stopped immediately. He might have something interesting to say, but apparently not important enough for him to write about it himself, so not important enough for me to read it either.
