I got a device built around an u-blox LEA-5T a few years ago and finally decided to set it up on a FreeBSD based machine.
It is connected through DB-9/DE-9 serial port because to get able to get PPS out of it.
PPS is on the CTS pin and the OS (FreeBSD) has been configured for this through system tunables.
PPS is working on the device but I get this in the logs, sometimes minutes apart sometimes almost an hour apart
kernel reports TIME_ERROR: 0x2307: PPS Time Sync wanted but PPS Jitter exceeded
ntpq -c reports this for the devlice:
remote refid st t when poll reach delay offset jitter ============================================================================== oGPS_NMEA(0) .GPS. 0 l 11 16 377 0.000 -0.003 0.004
Does anyone know what this message actually means and what can I use to correct this?
Thank you and have a nice day!
