[Milsurplus] Cyber threats prompt return of radio for ship navigation

[Bruce Gentry]

In addition to loran,  existing Non Directional Beacons should be 
preserved and dormant ones revived. ELORAN was SUPPOSED to be backwards 
compatable with existing LORAN C receivers. I have a hand held portable, 
and within reason, it would work indoors. Tests of ELORAN in city 
centers have been very encouraging for navigation and time signals. With 
autonomous vehicles under development, using a combination of ELORAN, 
GPS, and inertial navigation cross checking each other would give far 
better position reliabilty than GPS alone. Putting all of the tech eggs 
in one basket has been a foolish mistake.
