gps for time

I need a basic GPS receiver to set the time on a remote PC. I've been
looking at the Holux GR-213 G-Mouse GPS Receiver; it's cheap and small.
Location accuracy is not essential; time is more important than location.

Can anyone confirm that it can provide time as well as location? I think
the NMEA string is gpzda?

Thanks,

If time is important, you need a 1-pps output from the receiver. The Garmin 18
is considered a cheap and reliable time machine.

Unless better than 1-sec accuracy is important, a 1pps output is not required.
The latency in using an NMEA sentence will be less than 1 sec, more than enough
for setting PC time in all but the most stringest applications.


The O/P's cited sentence $GPZDA ("Time & Date") is obe of many containing the
required info, and is NOT a feature of many receivers. More likely ones are
$GPGGA and $GPRMC.

OK, thanks. To clarify, I don't need great accuracy; for my purposes,
knowing the time within 1 minute will be plenty. Location within 50
meters is fine. I need to time-stamp photographs with the time that they
were taken; the photos are taken in 15 minute intervals; I also need to
loation stamp them so I know where they were taken.

The embedded machine I am using has no battery backup for its clock, so if
it loses power it resets to an arbitrary date. I could add a battery
backed RTC but since I have a USB port it would be much simpler to add a
GPS puck that can provide the time and date.

So, to sum up, I am looking for a basic, simple USB puck that can provide
time as well as location info.

If you embedded box is running Linux have a look at GPSd
(http://gpsd.berlios.de ) - it runs as a daemon and can syncronize GPS time
with local time. And you get an API so you don't need to do everything
yourself.
