Shouldn't We Have Had This Discussion Before We Defunded eLORAN?

BBC News:

Sat-nav systems under increasing threat from 'jammers'

Technology that depends on satellite-navigation signals is increasingly threatened by attack from widely available equipment, experts say.


A UK meeting outlining the risks was held at the National Physical Laboratory in Teddington on Tuesday.

The approach still costs in the thousands and is the preserve of what Professor Last calls the "real techies", but he guessed that the tools could be in the hands of criminals within a year or two.


Some at the conference suggested the relative security of the eLoran ground-based system that is already in place, but which existing consumer devices do not pick up.

Actually, such devices had been designed, and were ready for market once this system was ready for them. Of course, now there will never be such a system in the USA. Much of our civilization, from navigation to timekeeping, is now completely dependent on one very good, but very vulnerable, single system.
