Magnus,
Most GPS simulators only have an OCXO in them which are not very good for
making precision timing measurements. The simulator needs to have a
rubidium in it or have an external input for a more precision frequency
source.

John,
I would advice you to look at what Spirent and Pendulum can offer you
with regards to GPS simulators. The Pendulum GPS simulation should be of
interest as it is a fairly decent cost, where as the Spirent equipment
is really really good. One way to characterize PPS properties is to do
it against a GPS simulator, which would allow you to remove some
uncertainties compared to live signal.
Said's pointers are indeed a good start, so I only wanted to give an
extra dimension which you might need.
Cheers,
Magnus
