I'm looking for info on designing a clock using a GPS synchronisation.
I have build clocks in the past, using an AVR & a watch crystal. Its
only the GPS aspect that's vague to me.
I searched Google, but the info seems too scattered & inconclusive.
Has anyone completed/undertaking such a project? Can you share some
pointers on this?
"Time-Nuts -- Precise Time and Frequency for Amateurs"
http://www.leapsecond.com/time-nuts.htm
are the people that take measuring frequency and time
to *Absurd* levels of precision. Kind of like
why people climb mountains, because they can. :-)
Lots of good practical advice as well.
The One-Pulse-Per-Second output of the GPS receiver is usually
uses to "discipline" some other oscillator.
http://www.arrl.org/qex/ QEX Magazine has had articles on
doing this in the last year or so.
What exactly are you trying to accomplish, as there
maybe other options besides GPS?
