A Nationwide RTK Network: A Great Idea, But?

Some folks are proposing that a nationwide RTK Network (RTN) be piggy-backed on the controversial LightSquared communications network. That could be cool, if it can be done. No one is saying that it can?t be done, but there are reservations on whether it would be worth the massive investments needed to pull it off, and that there might be little gain at all over the existing presence of RTN in the U.S.

RTN are arrays of continuously operating GNSS reference stations that can provide correctors for high precision positioning. Centimeter positions instantaneously; imagine what could be done with a capability like that. People have not only imagined such things, but have implemented over 100 of these in the U.S. and over 350 worldwide serving industries such as surveying, mapping, construction, precision agriculture, science, machine control, public safety, precise navigation. If you feel you have heard all of this before, you probably have, and chances are you might have heard this from an RTN junkie like me.
