Garmin GPS V and NTPD
 
Hi,

I want to set up my computer to be able to update its system clock to the Garmin GPS V vi ntp. This way I can also use this same computer as the ntp server for my lab LAN, which has no access to the outside world at all. I know that ntp makes references to clocks with something like this:
Code:

server 127.127.30.u
this is actually the reference driver for one of the Motorolla gps system.

The problem is that I can't find a way to reference my gps system which is the Garmin GPS V. Has anybody been able to do this. I know the is a PyGarmin thing out there, but that is not the solution that I am looking for.

Thanks
Figa

What are you looking for? I haven't look at the manual yet but I expect the data output to be in the NMEA 0183 format.

You would need to write an application that strips out the time part of the RS-232 ACSII text message and then sets the PCs clock.

After a little web searching I found the following which might be helpfull.

Depending on your accuracy requirements there are GPS receivers designed just for being a time source.
