I understood that the original reason for encrypting the low-order bits was 
to guard against enemy ICBMs being targetted directly on top of friendly 
silos. The thought was that if you're lost at sea, getting accuracy to 
100m-200m would get you in sight of where you want to be, so it was good 
enough for GPS.
