Under normal conditions, the Gold Codes on CDMA are synchronized to < 100
ns.

Is that a full time synchronization, or something like a PPS where they can
get the ticks lined up but not know the time for any individual tick?

The GPSDO sends out a pp2s that is specified to be aligned to GPS time to within
100 ns. The transmitter lines up to this “ever other second” pulse. There is normally
a serial link that tags the time.
