Look at how well a couple of projects have gone:
o privatize NIST NTP server operation - the NTP pool is recommended everywhere
and good enough for most; separate providers supply high accuracy, precision,
and stability timing for financial markets internationally; and GPS serves the
rest
o
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

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).

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. :-)

Hi,
There is indeed investigations going on about what the cost of receivers
would be etc. A benefit of Loran-C is that relative jamming/spoofing
resistance can be had without the need of opening up for keyed
receivers. This helps for non-military and non-government operations.
Now, there is

It certainly keeps trying to return. It will not be the navigation system

The reason to stay with the LORAN C style pulses is very very simple. It

Not to be to much of a downer here but …..
Loran for timing and an “Eastern WWVB” are two projects that seem to each have
a
life of their own. They seem to come up on some sort of cycle related to sun
spots.
Both have zero (or possibly less than that) percent mind share among those who

How much money was saved by not sending NIST time codes over GOES

probably not even 1% of that.
