hi
I am somehow new to ntp. I am interested to sync a windows OS to GPS time.
I have installed meinburg's ntp demon
"[email protected]" inside win_server2008.
1-Is it possible to use a GPS receiver module (which also has PPS) to sync the
pc using installed ntpd ?
2-Dose NTP able to use NMEA massages +PPS signal to sync PC's time?

1. Yes, send the PPS signal to the DCD pin of your COM port. Usually a
TTL-level signal will drive an RS-232 COM port. This is what I have on
one system for a Sure GPS/PPS source:
server 127.127.22.1 minpoll 4
server 127.127.20.1 minpoll 4 mode 18
fudge 127.127.20.1 time1 +0.335 refid NMEA
2. Yes, like the arrangement above.
You will find more information (but not, perhaps, a step-by-step guide)
on my Web site. I suggest updating to a more recent version of NTP and
Windows executables are also on my Web site.
