[time-nuts] GPS-based frequency reference in "Everyday Practical Electronics"

[Don Key]

Was just catching up on my past issues of "Everyday Practical Electronics" when I noticed that the April & May 2009 issues featured a constructional article for a GPS-based frequency reference.

It is based on the Garmin "GPS 15L" module, and the unit provides a 10MHz, 1MHz & 1pps output. It has an LCD display to show time, date, position, number of satellites etc.
