I have previously voiced my skepticism of Galileo's business model as a European GPS provider, as well as reported on many other public critiques which were unfavorable- Now it turns out that the Galileo paid subscriber business model has shown it can be compromised. According to Science Daily, a team at Cornell, when frustrated with the lack of cooperation, were able to monitor Giove-A signals, and able to perform signal processing to reverse-engineer the algorithm used to generate the Pseudo-Random Numbers (PRNs) essential for processing the transmission.

There is nothing in the article indicating that it is the protected codes they reverse-engineered. It could might as well be the someday-to-be public codes when the system is up and running.
G'day mate.
Very interesting.
