For what this is worth (not much, probably) the U.S. Coast Guard had plans some time ago 
to use the old 600 meter band for ground-based GPS systems.

They never got any funding for it, although they did build and install a couple of such 
systems.

I know this because this issue came up when I was trying to get 600 meters for use by 
hams. I started that process over 20 years ago.

Personally, I think it is a big mistake to put all our navigation eggs in one basket.
