I have a GPS device on my box and would like to use its PPS (I believe
it's the $GPRMC message) as a reference clock for ntpd? I assume it's
possible? Currently, there is no driver for the GPS device, I'm
getting position updates by opening the ttyS0 comm port and reading
$GPGLL messages.
Any ideas?
This question would be better if asked on comp.protocols.time.ntp (where
I've directed followup). There is a generic NMEA driver that probably
does the right thing with the NMEA messages (I'll let the experts
confirm this).
When you say "[I] would like to use its PPS" I'm assuming that what you
really mean is that the GPS receiver outputs a PPS signal (on one of the
pins/wires) that you would like to use. Google PPSkit, or look at
recent postings in comp.protocols.time.ntp.
