Lady Heather does measurements on the arrival time of message vs the time
encoded in the time message being used and compensates the time code for the
offset. It uses a default value that depends upon the receiver type or can use
a user specified value. For generic NMEA receivers you should

There were MANY models of the KS-24361 (RB, XO, REF-1, and REF-0) on the
surplus market.
The SUBJECT of my T-N posting was standalone operation of the REF-0 model,
which has NO GPS receiver and relies upon other KS-24361 models (like REF-1) in

Some models ONLY function as a Time Server (NTP) for a Local Area Network (LAN).
The 9520 model numbers vary in the presence of the LCD on the front panel, and

Hi
On many receivers the buffering process on the messages has an impact on
arrival times.
If you *only* use one message and never use any others that might not be a big
deal. Most
applications use a number of messages to be sure that the software knows what
is really
going on.

On this list? What sort of response were you expecting?
I'm interested in NMEA timing for use with NTP.
There are lots of low cost GPS units available. Most use USB.
Hi
So …. who else is going?
