Cornell Researchers Crack GIOVE-A Code

The prototype GIOVE-A satellite, a testing ground for the Galileo GNSS has been broadcasting a signal since January. But no one could use it, save the few privileged organizations involved in the project. Some of Galileo's signal are supposed to be "open source," but none on GIOVE-A are.

So, members of Cornell's Global Positioning System (GPS) Laboratory got to work (with the OK of the university's lawyers) and de-coded the "so-called pseudo random number (PRN) codes." That reports the Cornell Chronicle Online, "means free access for consumers who use navigation devices -- including handheld receivers and systems installed in vehicles -- that need PRNs to listen to satellites."

The Cornell team documented how it did the deed in GPS World.
