[time-nuts] 1PPS users?

[David J Taylor]

From: jimlux

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.

Cheers,
David
