  Are you saying that's what the decoded message from the satellite says?

More awesome DSP detective work by Daniel Estevez. One of a very small number of authors/sites I upvote reflexively as soon as I see them show up on the page, before even following the link. If more people understood what this guy is doing, he'd be up there in the HN pantheon with Carmack, Bellard, Ken Shiriff, and Bunnie Huang.

  Yeah destevez has spent a long time doing this and now there's this modern #hearsat style crew who both receives the satellites and writes decoders for them. And it's almost fully fresh blood with young folks.

This post has been in the front page for more than 24 hours, and it has been unavailable to access for the majority of time. It's weird that it's still on the front page, also given the low number of points and comments it has... It also says it has been published 3 hours ago, which is not true...

  Maybe it's getting boosted from the second chance algo?

    Yes, second chance pool. It's available on archive.org here: https://web.archive.org/web/20221030180939/https://destevez.net/2022/10/decoding-integral/ https://web.archive.org/web/20221030180939/https://destevez....

Lot's of references to a Blue Book that describes the various methods of encoding data in the signal. That's a lot of heavy lifting being done for the person doing the decoding. There's still a lot of work to get to that signal though, so I'm not dismissing any of that effort. What would be curious would be how long to decode a signal without that reference book. So for example, if we received an actual data encoded signal from another country, another planet, etc. Something reminiscent of Contact. How do people go about finding that "primer" to show them the way?
