It was never my point that GPS could not be jammed. My point was,
and is, that such jamming would by necessity be relatively short range
because of the microwave frequencies involved. The only exception
would be some sort of systemic jamming that originated within the
satellites themselves. It's my understanding that jamming of that
sort would affect all users.


So how exactly are we going to create superior charts in regions with
no GPS coverage? Or what use would these charts be to a sailor trying
to navigate a tricky coast without sat nav to give him his position?

Better get out Lecky's Wrinkles in Practical Navigation, hmm?
