Bob:
Right now I own nothing that outputs a GPS PPS. GPS watches I own do
not have that option. Maybe for infrequent resets, an independent
GPS unit is better from a design and construction POV?

Hi
A GPS PPS output will (most likely) be more accurate than the CSAC
each time you go back to dock with the charger. A GPS module to do
everything you would ever want to do is a sub $100 sort of item. You
would still need a bit of hardware to “glue” things together (but not a lot)
and some code running on the MCU of your choice to supervise the process.
Accuracy wise, a GPS PPS is *very* hard to beat.
