This is from my system with Sure GPS.

Seems to be similar to yours. I don't have a clue as to stratum and
refid as this is first time I've used ntpq clockvar.


associd=0 status=00f1 , 15 events, clk_no_reply,
device="PPS Clock Discipline", timecode=, poll=96503, noreply=300,
badformat=o, baddata=0, fudgetime1=0.000, stratum=16,refid=80.80.83.98,
flags=4


associd=0 status=0119 leap_none, sync_pps, 1 event, leap_armed,
version="ntpd 4.2.6p5 at 1.2349-o Tue Dec 27 09:47:55 UTC 2011 (1)",
