Be aware that many 'personal' GPS receivers will have more delay
in the serial output circuitry, which is not accounted for, and
which may not be constant delay.

Also, naturally NTP's concept of 'stratum' differs from the
telecom world's concept of 'stratum', so be clear on what
accuracy you want.

If you just want a solid clock source that's always <1s off,
a recreational GPS may be fine for you.
