I connected my new active antennae from SparkFun (GPS-00464) to the gpsstix.
The gpsstix has the LEA-4h chip from u-blox.
at first i didn't get any data from
# cat /dev/ttyS2
but when I moved the antennae so it hung outside, i got a lock on satelites.
I copied the script gpsparser.pl from here and started getting good data streams:

yes, now you can send a Scud to me :-)
I added a few more parsing lines to the perl script and now it outputs:

easier to remember for debugging. Will use a compressed string later.
Uploaded the raw data to http://www.gpsvisualizer.com/ and it generated this map:
Pretty cool. Not only the right house, but the right location in the house....Next step is to wire up the LCD and take this thing mobile.
