Hello all,
While researching potential GPS modules to experiment with for PPS
output, I discovered that SparkFun has quite a lot of modules, some of
which have PPS and some of which don't. You can't necessarily tell
from the product page. You have to check the data sheet. You can go
to their website and search for gps. This link should also work.
Just thought I'd pass it along.

Here is one unit which does have PPS but it's not obvious from the
product page. There are others as well.
12 Channel Copernicus II GPS Receiver - from Trimble -

Here are the parts of a pretty cool article referenced on the SparkFun
site regarding interfacing to these type of modules. About 70 pages
of info not counting the data logger article.

Chris Albertson sent me a note pointing out that these GPS modules are
just little "bricks" so to speak, and need a circuit board to work with
them. After doing some more searching on SparkFun, I found these links
to some interface boards. There may be others as well.

I get about 300 emails per day from alternate energy mailing lists and
such. I don't always see new messages very quickly. If you need a
reply and have not heard from me in 1 - 2 weeks, send your message again.)
