Galileos Prn Codes Cracked

artcile on cracking codes

 

FTA:

Newswise — 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.

I personaly believe that Europe should have collaborated with the US in the GPS system instead of building its own. The excuse is that the US system is a military one and the US army could at will make it useless for civilian use. Yes but what about GALILEO being used by unfriendly nations or terrorists ?

Will Europe block it or will the US have to destroy Galileo ?

 

We all know who are the rogue countries that may become a threat to the western world and unfortunately France (at least its current leftist governement) is too friendly with these nations, leading Europe on the wrong track.

In all honesty, in this day and age, I don't think it really matters. Even though the US government could turn SA back on if something like a war happens, I think they too came to the conclusion that it doesn't really matter anymore and thus they allowed SA to be deactivated.

 

For one, there are plenty of alternative guidance systems. Secondly, if you are off by 100m vs. 10m you still probably end up damaging your target (especially for terrorist behavior, which doesn't really care much what it hits so long as it causes death and, well, terror). For a "precision" stike against a military facility surrounded by civilian facilities, yes, it will be off, but the counties you are implying with your statement aren't of the nature to do "precision" stikes. And if they did, again there are other guidance systems available that are more reliable.

 

And then there's the whole "big boom" factor of someone launching a nuke or other "large" warhead and then it really doesn't matter if they are 10m or 100m or even 1000m off...
