So a couple of researchers at Cornell broke the PRN codes for Europe’s Galileo GPS satellites. It’s a $4 billion dollar investment that, unlike the US satellites, was supported by private investors expecting to charge for access. Except they protected the system with codes that were broken in 1 week, without any serious computing power, using only Matlab and a dish receiver, by non-crypographers. There’s also a lot of background story to the issue, since the US doesn’t have the ability to turn Galileo off, should we decide who’s next to liberate.
The first satellite was at 36 degrees declination from NY, so I’m not sure if its visible from CA, but here’s the PRN. Maybe they’ll do a better job next time.
