We can quite reasonably hope that the system will never go out, though
with the problems NASA has been having with the space shuttle and
satelite launches, who knows?  The cheapie GPS receiver you have on
board is quite another matter.  It is susceptible to lightening
strikes, getting crunched, dead batteries, falling overboard and so
on.

Has anyone ever heard of a vessel loosing all of its GPSs while at
sea?  If it hasn't happened yet, I suspect it will.
