GPS clock timing !

[bethr]

Hi there Bethr,
I am looking at purchasing a garmin LVS gps for a robot project and I was just wondering what kind of gps you are using? Cost? etc....

currently I have two modules

this:



http://www.trimble.com/embeddedsyste...?dtID=overview

and this one , a low profile asian embedded device:



both were removed from used equipment, but I know that the trimble module have a cost near to 50 usd (versus qty)
and the other one near to 30 usd

both devices has NMEA ascii output @t vdd levels, trimble vdd=3v3 and asian device vdd=5v

Cheers !!
