Re: [PSUBS-MAILIST] Navigation Jim I think
navigation would be a good topic for this group to discuss. I for one am at a loss
for a solution. I so like my gps system on my surface
support boat I want something decent under water. How does the military do it? Lots of
money I am sure but seems something better than a compass
could be done. I am leaning towards a tracking beacon on
the sub and get nav directions from support boat. Dean In a message dated 2/12/2011 11:42:17
