Galileo is Europe’s answer to the US tax-funded GPS system. GPS is free to use to anyone with a receiver – but Galileo needs to reimburse its investors somehow. Because they share bandwidth, there was a deal that said some of the codes for Galileo had to be put in the public domain. When this failed to occur, a team of Cornell University researchers reverse-engineered the signals and cracked the codes anyway. Information wants to be free, but sometimes it needs a little help, I guess.
