And pretty much any of these will ingest a 1pps + message, rather than,
say, a 10 MHz reference.
Why not just use the raw GPS 1pps (which is typically good to a few tens
of ns)? GPS coverage/outage and random variation in the GPS 1pps
A lot of them use a disciplined oscillator to generate the 1pps, so the
oscillator is essentially a long term averager/low pass filter on the
raw GPS output -
Having the GPSDO/PPS is handy when someone parks outside your location and
carries a GPS jammer.
