Cracking the GPS Galileo Satellite
Glyn writes "Newswise is reporting the the encryption in the Galileo GPS signal has been broken. The pseudo random number generator used to obscure the information stored in the Galileo GPS signal has been broken. From the article: '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.'"

There is: the "American GPS" is named NAVSTAR according to this site
The article is inacurate and makes a big deal about nothing (BTW did you notice it was written by a guy from Cornell ?) First, Galileo is not ready yet. The article claim they plan to charge for the keys. This is plain wrong, the base precision signal (which is the one we are talking about) will be available free of charge. The system is simply in testing phase right now and they don't want anyone playing with it, that's all. Second, this PRN sequence is not supposed to be difficult to crack at all, since it will actually be made public in time. This is in no way an achievement. It is was the high precision signal, this would be another matter.
The sooner you fall behind, the more time you have to catch up.
Cornell demonstration is pretty useless.
First Galileo is only in testing phase, therefore nothing tells you the signal encryption they are using is the definitive one. I would rather think they are testing and they don't care if someone is getting it.
Second have you ever heard of firmware upgrade ? I guess encryption will be updated when the satelites will be in production, and there will not be any problem since it is not being used in any device yet.
Thank you Cornell people for this useless article. Another Cornell box ?
Not many people remember it, but there was a third competing system for Global Positioning.
GLObal NAvigation Satellite System
Started by the Soviets, cont. by the Russian Federation, and now with India on board,it is expected to be fully operational again in 2008. (Like all things expected to be complete in 1991, the money situation made them push it back further than Vista.)
Windows has detected an undetectable error.
It's obvious that the EU will force all mobile phones, cars, planes, etc. sold in Europe to use Galileo. The free market would never adopt a new alternative that is not technically or functionally superior, is going against an entrenched competitor with a huge install base, and costs money where the alternative is free.
You need to check your assumptions.
The EU doesn't mandate GPS/Galileo in anything. The US does.
Galileo is functionally superior. The free precision will be better than with just GPS.
There is no installed base in high precision applications because there is no product on the market. Only the US military has global high precision positioning.
Galileo's normal precision code will be free, just as the base level precision of GPS is free.
Galileo's high precision code will be available commercially, whereas the GPS high precision codes are not available to non-military users.
me-too project [...] A380
The A380 is not a me-too project. Americans only even know that name because it is a real threat to Boeing, who chose not to build a plane of that capacity. It's not someone else's plane, only slightly bigger, either. It's the continuation of Airbus engineering, which is very different from Boeing's.
In other words, we just added an entire China
Unfortunately for you, that "China" you added belongs to foreign investors.
