My latest test version of ntpd for Windows adds support for refclock_atom using PPSAPI. This is only available for PPS connected to a serial port CD pin, and requires use of my patched serialpps.sys.
As with prior versions you can still use a NMEA + PPS source without my patched serialpps.sys installed. If you use such a refclock with my serialpps.sys, you'll get better timestamps and reports every two hours of the latency between the interrupt-time serialpps.sys timestamps and the user-mode PPS timestamps you would be using without it installed. http://davehart.net/ntp/refclock/serialpps-20090301.zip If you wish to try serialpps.sys and are on a 32-bit system, download that .zip, extract all files, and run the enclosed install.bat. If you're on a 64-bit system you could be the first to build a serialpps.sys for your processor architecture, after a hefty WDK download, DVD burn, and install. Contact me if you have a 64-bit Windows system and are interested. http://davehart.net/ntp/refclock/ There are 5 .zip files for the latest 20090301 test version of ntpd with refclock_atom (127.127.22.x), but most people will only want: http://davehart.net/ntp/refclock/ntp-4.2.4p6-DLH-QPC-20090301-bin.zip http://tinyurl.com/bzpq3f Cheers, Dave Hart _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
