They could put the new station on 60 kHz as well. If they can't get

Joke's on them. GPS time is implemented by the atomic clocks in the
GPS ground control stations and the GPS satellites themselves. Since
it is not updated with leap seconds, GPS is currently ahead of UTC by
14 seconds.

Easily compensated for in the software.

Well, that part of it is, but see my reply to Geoffrey's posts on the
subject. There are other issues with using GPS as a time standard,
which are related to the quality of the algorithms GPS receivers use
to process data received from the satellites, as well as variations in
the circuitry used to control receivers' internal clocks.

Did you visit the ESE web site? They make the master clocks used in
broadcasting (and a lot of public service and labs) and they have very
well thought-out innards.

Is GPS like NTP in as they just give a raw number of seconds since a
certain date and that the receiver computes the real time from that,
based on its firmware?
