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.

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.
