[time-nuts] Trimble Resolution T - PPS offset and stability

Hello.

 

Has anyone here tried varying the PPS offset on a ResT (or UT+ or any other
GPS receiver for that matter) and measuring the resulting stability?

 

I ask because my Rb has only a 1PPS output, and while I have been able to
get at one of its internal HF signals, would like to see what I can do with
just 1PPS.  The obvious problem with doing this is that I will need to align
the PPS outputs together to get reasonable accuracy, but I worry that a
large offset in the GPS receiver will degrade stability as the pulse moves
away from the relevant packet in the GPS signal.

 

Am I being over-cautious?

 

Thanks,

Lachlan
