Loran-C had absolute accuracy to 500nS but repeatability much better,
usually to about 20 meters position or 60 nS (if you mark the position
of a buoy you can get back to it very closely). eLoran is a significant
improvement and appears to be able to get to 8 meters absolute position
or about 25 nS timing. Each transmitter would have its own cesium clock
instead of the slaves relying on the master and propagation corrections
would be cataloged and disseminated.

I don't know if there was. But the timing receivers like the Austrons and
SRS could really derive very accurate frequencies especially if you lived
60 miles from the transmitter. :-)

Time-Nuts,
Was better than 500 nS accuracy ever achieved with Loran?

Folks,
I know that there is a longing for LORAN-C to return, but this weekend, I
did a Google Maps flyover of each of the US LORAN-C stations (takes less
than an hour). Almost all of the antennas are gone and there are no cars
in
the parking lots (except at Seneca which became an Army depot). This
means
that the equipment is probably gone, too. Or maybe this stuff will show
up
at auction or on E-Bay and that would solve the Austron receiver
problem..
