That is also what I like to understand, and when combined with a FE 5680A
the time will be long and should be averaged over 100 if not 1000 samples,
what is the advantage? Look at the error budget.

What is it these u-blox device can do that a cheaper Motorola Oncore
can't? Depending on the version the Oncore has for 50 to 5 nS
one-sigma error on the timing pulses and can do either 1PPS or 100PPS.
Single unit prices are from $18 to $60 very good documentation is
available.
If the u-blox was somehow much better than a Trimble thunderbolt or
Motorola Oncore MT12T I'd buy one even at the above price. But
really these older GPSs are already at the single digtit of
nanoseconds level and I don't see room for improvement except....
If the L2 band is also used. This is the way to get order of
magnitude improments
