This might be of some interest to some here:

The pinout diagrams show no PPS pin, and no free/unused pin either.
If the normal/sleep pin could be converted from an input sleep signal
to an output PPS pulse, then it would work, but I don't think that is
likely.

looks like sending of the GPZDA sentence is synced to (internal) PPS
ask the manufacturer?
It would still be limited to the resolution of the rs232 clock, i.e.
~1ms, instead of the ~1us we usually get from PPS receivers.
OTOH, for many users 1-3 ms might be just fine, and statistical
processing might make it stable at the sub-ms level, but with unknown
absolute offset.
