Hello to All,
I was wondering what accuracy can be achieved with radio clocks (I live
in UK, so I would use the Rugby MSF transmission at 60KHz)
I understand that issues like calibration for radio propagation may be
required, but I was wondering about your experience with radio clocks.
I am also interested about stability of the offset (for my application
is more important than absolute accuracy)
Thank you.
Regards,
Mauro
I'd say that performance depends almost entirely on how good your
reception is. If you get a good, solid, signal 24 hours a day, your
accuracy should be within a few milliseconds. If you can live with +/-
five or ten milliseconds, go with MSF.
My own preference would be for GPS. I get better than 5 microseconds
and a server that is so stable that I can maintain synchronization
within a millisecond or so on my LAN.
You probably will want to check out Jonathan Buzzard's "Radio Clock".
He has a design for a timing receiver consisting of a integrated circuit
receiver chip, an antenna, two transistors and a power supply. There
may be a couple of resistors in there too. It looks incredibly simple
to put together. I think the budget for parts is something like $60-$70 US.
