    Absolutely YES

  2. J. Michael Taylor says:

    I worked as a lead system engineer on the GPS IIF system. I think it was a mistake to shut down the current Loran system because our adversaries are becoming more adept at shooting down space objects such as a GPS satellite.

  3. Most definitely yes. 8 years of research into GNSS vulnerability has illustrated a vulnerability to one of the most fantastic machines man has ever created. That’s whu Chuck Schue and I have set up Taviga.

  4. Yes, the case is overwhelming – as it also is in Europe. But once the eLoran system has been re-established it should be commercially operated with government departments paying for the services they use.

  5. I vote yes, but have concerns about the lack of LORAN stations in Australasia. Will the investment to get the legacy systems up and running be viable for governments around the world? Will eLORAN be seen by many as an interim technology to solve a potential threat with a bandage approach? If it was to become commercial, how would you control who is using the signal?

  6. JJM says:

    YES – Relying on 1 technology with all the space based systems all within the same frequency range is foolish.

  7. Ted Cernak says:

    I’m a big believer in redundant systems when safety is involved.
