Hi Magnus,
 
Just read up on their website, they cannot disable the WAAS signal because  
it would disable all GPS WAAS landing approaches in the USA. A very big  
deal. When it fails, they will be landing aircraft with only one GPS bird for 
a  while, and no backup!
 
So it will continue to transmit, until it looses earth-lock, which they  
expect to happen in the next couple of weeks due to the Sat's momentum  wheels 
saturating..
 
Exciting stuff!
 
BTW: seems like no one is monitoring this on their GPSDO's?
 
bye,
Said

If it  still has power, oriented in the right direction (antennas down) 
and they  keep beaming signals to it, it will work. If they don't beam 
signals into  it, it would still sit there and broadcast, so they might 
as well use it.  The best thing for them would be a loss of orientation 
control if not a  complete power failure would save them. If it spins, it 
will get less  power and less amount of time it would be facing the earth 
with it's noise  transmissions.

Cheers,
Magnus
