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=,

associd=0 status=0119 leap_none, sync_pps, 1 event, leap_armed,
