I currently operate a stratum 1 NTP server in the NTP pool using a U-Blox
Max-7Q GPS module with PPS attached to, variously, a Raspberry Pi via GPIO
or a Celeron mini PC via serial DB-9. The machine does nothing but serve
time to the pool. Operating systems of choice are Debian or FreeBSD.
What would be my next step up be, hardware-wise, in terms of improving
precision, stability, etc? A GPSDO? Budget is limited as far as these things
go - about £150 UK/$210 US.
I appreciate this is basic stuff compared to the usual discussions but this
doesn't seem the right question to ask on the NTP lists. Any help
appreciated. Thanks.

Neil,
A BeagleBone Black might give half the jitter compared to the RPi, but not
the order of magnitude you may be seeking.

Perhaps purely for serving the pool, the RPi is more than adequate.
Cheers,
David
