Step 8Test it out!
Screw on your antenna and fire up the gumstix! Do a cat /dev/ttyS2 to view the raw GPS data stream. How do you knwo if it worked? do a cat /dev/ttyS2 | grep GPGGA to just see the GPGGA sentences (They contain time, latitude, longitude, ebaring and some other stuff). If the GPS isn't seeing any satallites you will see something like:
$GPGGA0,00,99.99*48
Don't dispair yet, make sure that the antenna has an unobstructed view of the sky, this is important! Let it stand for a few minutes. If nothing changes then go back and check for short circuts or broken connections. If it worked you should start seeing stuff like this:
$GPGGA,141812.00,4221.7816,N,07105.9727,W,1,03,2.45,00033,M,-033,M*59
HUZZAH you have a lock and your location is 4221.7816 North longitude by 07105.9727 West latitude!

Useful piece of info. Thanks. Any suggestions on where other software usage resources with the gumstix hardware are found. gumstix.net and its wiki is not that interesting at this moment :-).
