Galileo Satellite Code Cracked
Members of Cornell’s Global Positioning System (GPS) Laboratory have cracked the so-called pseudo random number (PRN) codes of Europe’s first global navigation satellite, despite efforts to keep the codes secret. That means free access for consumers who use navigation devices—including handheld receivers and systems installed in vehicles—that need PRNs to listen to satellites.
Security by obscurity: it doesn’t work, and it’s a royal pain to recover when it fails.

As I understand it, Gallileo uses broad spectrum broadcasting and the PRNG is used to spread the signal over the spectrum and is not neccesarily a security device. Presumably it would be made public when the system goes live, but right now is simply undocumented.
