Magnus,
Drop the receiver and antenna out of the equation and
just provide a timing signal on launch pad...
I need to keep computers time synchronized from launch through at least
arrival on orbit so that time-tagged network messages can be played back
with some degree of fidelity. For this, I need the time source on the
rocket. Using a GPSDO in holdover mode seems like a good solution.

Some GPSDO "learn" their hold-over parameters over time,
sometime days, in which case you may be in for a surprise.
Is there any way you can simulate the temperature, vibration,
and g-force (or lack of) trauma that the GPSDO is going to
experience during this hour of launch-to-orbit?
If not, I suggest a simple test: just throw your GPSDO and
battery in a backpack and go jogging. Twirl the backpack in
the air every now and then. After an hour I'd be very curious
by how many microseconds it's off.
