Somewhat time related.  The Navy realizes that GPS might not always 
work.  I don't imagine that aircraft in the US Air Force will be able to 
do this very reliably, and the article doesn't mention that service.  
I'm guessing that a lot of strategic Air Force aircraft have star 
trackers that will work some of the time w/o GPS (at night).
