What if you use a navigation GPS unit rather than a timing unit?

How long does a survey take (in good conditions) and what sort of time 
constant would you want to use with a navigation box?

Does anybody have graphs of the PPS wander from a navigation unit?


I like the lock-to-rubidium suggestion.
