[time-nuts] GPS and Rubidium frequency standards and noise question (newbie).

[Chris Albertson]

If you want a frequency reference.  There is nothing better than GPS.   In
fact it you bought a Rubidium you would still need the GPS so you could
calibrate its frequency.

Some GPSes might be noisy but then you can lock a good double oven crystal
oscillator to it and have what they call a "GPS disciplined crystal
oscillator or "GPSDO".
