I would suggest that you could consider one of the Garmin GPS 16/17
models, that have been offered by Fluke1(China) at a sensible
price. I have a GPS 16HVS which is performing very well just
sitting on a window-sill (facing North), this offers a 1pps timing
signal. It requires between 8.0 to 40 volts D.C (nominally 12.00
volts @ 40 mA. The alternative model, 16LVS, requires 3.3 to 8.0
volts.D.C @ 65 mA. All the data on these devices is available on
the Garmin website
Good luck

Subject: [time-nuts] GPS with PPS
Does anyone know if any of those all-in-one hockey puck GPS receivers
put out PPS on the serial cable? The type that has the antenna and GPS
together, with a serial cable hanging off of it. I'm thinking about
using one for a timing project. The more sensitive, the better, as it
will be used indoors.
While I'm on the subject of GPS units, a question comes to mind. I
know that WAAS enhances position accuracy. Does it do anything for
time? My first thought would be no, as that comes directly from the
standard GPS satellites.
Thanks,
Joe Gray
