I have a minute.
The loran c simulator is designed to support the older loran timing
receivers and allows them to be used to measure references. Systems like the
austron 2000c and 2100f etc.
So you only need 1.
For location you need at least 3 transmitters and at some distance and they

Hi
There are a raft of papers on each of the sub portions of the fitting
process. Aging, retrace, temperature, and acceleration all have their own
issues and fit approaches.
The whole how (and why that way) do they test a chronometer? is something
there's a lot of papers on as well. Some of

Jim,
Getting back to the original question, I'd suggest that the Epson-Toyocom

Nuts,
I have been unable to explain to some of the upside down experts out there, in
a way that they can understand, why the PLL Tester method works good enough for
many.
Maybe now that they can see that the simple PLL tester gives nearly the exact
same answers as the TSC 5120A over the whole

Isn't that HP/Agilent App-Note with the three wrist-watches the

Hi Jim,
If you are looking for low power ( 80 mW @ 24 degrees C), stable
(better that 1ppb per day) accurate (within 5ppb of 1Hz from factory)
then have a look at these devices.
