I would think the commercial air folks and commercial marine shippers would be demanding the next generation of secure GPS and ideally we recreational boaters will benefit too.
I have long maintained, "we" should jot down our position every 30minutes to 1 hour so if things "go south" we will at least know where we were.
It is one thing if we are on the ICW or a few miles off the coast..... but, if we are doing some serious off shore cruising, we need to know.
