  But if they had authentication you would know that the message doesn’t come from a legitimate satélite.

    If their isn’t then there’s a big problem with implementing that now, which would require a retrofit of every single GPS system currently in use and likely a replacement of all GPS satellites

      I would hope whoever designed the satellites had the foresight to allow remote software updates.

        They’re talking about the millions of receivers around the world, not the satellites.

    you can’t have authentication in a one way system. satellites send days, planes receive it, but never send anything.

      You can have a digital signature, so the recievers know it’s legit
