    That is nothing new if used just for navigation. It has been done before and wasn't very precise. Like +/-1 mile. The sub's inertial guidance is better than that. The USA gave up on VLF navigation in 1997.

    And at the data rates they mentioned, it isn't good for much more than "we need to talk".

    Still, I enjoyed reading about the technical difficulties involved.

    I have been in a plane with a VLF Omega receiver, it also had loran and R-nav (1989 after Exxon Valdez oil spill had several flights in it). The VLF Omega was accurate for in-route. The computer incorporated with the receiver was the ticket. Only one I have ever seen. Cool navaid. I was wondering if one of those old receivers could be found and reworked to use different frequency's. Just a novelty really but fun, you know … "what's that"?

    I'm sure you could find one somewhere. As for reworking for another frequency that is an entirely different question. IIRC, the Omega system used the RF phase difference between or more stations to fix your position. I don't remember any other details, but since it would be on fixed frequencies it's usefullness for other purposes would be unlikely.

    Beyond my capabilities but some people can do wonderous things with those crystals.
