  • Planes only use GPS because GPS has a very rigorous signal integrity program that others don’t have. The “safety of life” requirements on GPS are onerous. Also, GPS has both L1 C/A and L5 (not enough L1C or L2C to be useful yet) signals. I don’t think Galileo or GLONASS have extra signals, but I think Beidou does (not an expert on other systems).

    Just this January, ESA completed the safety of life analysis requirements for Galileo to be used as a civil aviation signal.


  • The only people who actually believe DJT is worth anything (both the person and the stock) are typically the kind of person I’m OK with screwing over. They gleefully cheer when harm comes to people I love, so I have no problem doing the same to them. Plus, his tax cuts for the wealthy actually increased my taxes a noticeable amount (the hard limit on tax exemption for high state tax areas), so I would feel like I’m just getting mine back from the people who voted for him.
