How to make a Holux M1200 bluetooth G.P.S. update your position in realtime in Google Earth in Gentoo Linux:
(adapted from http://www.gentoo-wiki.info/Bluetooth_GPS and http://tjworld.net/wiki/Linux/Ubuntu/GoogleEarthPlusRealTimeGPS)
1. Configure and compile the kernel the include bluetooth and hci U.S.B. support, copy it to your boot directory, and reboot.
2. Install bluez, gpsd, pyserial, and googleearth (if you don't have them already).
3. Turn on your G.P.S. and run
Code:
hcitool scan
, then copy the address of your G.P.S.
4. Put the security code for your G.P.S. in /etc/bluetooth/pin
5.
Code:
rfcomm connect 0 [your G.P.S.'s address] & gpsd /dev/rfcomm0

7. Go to http://www2.warwick.ac.uk/fac/sci/csc/people/computingstaff/jaroslaw_zachwieja/gegpsd and download gps.kml and gegpsd-0.2.py into /opt/googleearth.
8. Edit them accordingly (for example, change the port to /dev/rfcomm0, and the baud to 38400 in gegpsd-0.2.py, and modify line seven of gps.kml so that the path is ./realtime/Realtime GPS.kml
9.
Code:
mkdir /opt/googleearth/realtime

10.
Code:
chmod +x gegpsd-0.2.py & ./gegpsd-0.2.py

11. Start Google Earth, and open gps.kml. It should find your position automatically.
You have now made Google Earth communicate with your G.P.S. in Linux, meaning that you can use your computer (laptop, netbook, et cetera) function as a G.P.S. with real satellite imagery! If you plan to go to a foreign country, just run Google Earth, download some maps of the place where you're going and the surrounding area, and you'll know where you are and where everything is in relation to you; even if you've never been there before, you won't be lost, and you won't need to wonder where everything is (provided that you download the imagery/information beforehand on Google Earth).
