Mostly affects military users, but the lesson is clear on relying on a single system for mission-critical navigation http://www.gpsworld.com/gnss-system/news/gps-control-software-glitch-nanu-issued-9414 Please, no "see, that's why I'd rather trust celestial than GPS" -- the lesson is that ANY system (including the Nautical Almanacs and sight reduction tables) can have inadvertent or unanticipated defects.
