Hi all,
I'm currently using gpsd to interface
with my serial GPS, which is outputting GPGGA and GPRMC NMEA sentences
every second along with a 1PPS output. gpsd is connected to chrony
through a socket interface (both are running as root), and this setup
serves to set the time on my computer's clock.
This
setup works well until the GPS' fix is lost, after which chrony no
longer uses the 1PPS signal as a source of timing. The computer is also
not connected to any network, so it can't rely on other chimers. My GPS
unit is also driven by an OCXO, so theoretically the 1PPS signal should
still be accurate when the fix is lost.
Is gpsd doing
something to tell chrony not to use the GPS or 1PPS data when a fix
can't be achieved? Is there a way I can force this gpsd/chrony interface
to work without a 3D fix? Is this a gpsd or chrony issue?
Similar results occur when using ntpd. I'm new to the list, first time poster. Any help is appreciated!
From,
Alex
