So this does not apply to the Thunderbolt? It only has one port. If
it worked on all PALISADE type GPSes I'd do it.

NEMA is only used to number the seconds. It is the PPS that does the
timing. You don't gain accuracy with NEMA.
And interresting trick is to put two or more GPS units on the same
computer. then use NTP to compare. You can test out what works best
and measure the differences
