It isn't that simple. This is a test-bed satellite. The timing data  
on the cracked signal is not encrypted, it was a matter of  
determining the spread spectrum sequence. The sequence was something  
that was planned for dissemination, the crackers simply beat ESA to  
the punch.

In the functional system, the timing data will be encrypted. I do not  
know the details (or if they have been published) but you can bet it  
will not be something easily cracked, and furthermore, any attempt to  
do so would run afoul of the DCMA.
