[time-nuts] Next step up from basic GPS/PPS timekeeping

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.
