[time-nuts] eLORAN in the Antipodes ? (was: Re: eLORAN will be on the air GRI 99600)

[Taka Kamiya]

Wouldn't such a long distance propagation result in less precision?  The signal will have to go through distance through air which isn't constant in dialectic values.  Wouldn't it be problematic for level of accuracy we pursue?

 I believe South Korea is indeed building new eLORAN chains. I have seen
mention of it.
With respect to distance In the US I could occasionally receive the
European West chain at night and in the winter. Thats about 3200 miles. It
would also be by skywave so that deteriorates accuracy.
