A bit of an update after overnight run. The PPS jitter is often dipping down to 17nS which is the best I've ever seen out of a PPS timing system. Amazing considering it's just spread out over the bench in the office so is prey to electrical noise and air drafts and the GPS antenna has a poor view of the sky. I don't think its using Galileo right now, only GPS and GLONASS - there's some settings I have to tweak. The USB timing messages are giving a bit of a problem, arriving late and with high jitter which is causing ntpd to struggle. I've not seen that with any other u-blox GPS. I'm investigating that now. -- Paul Nicholson -- |
