moxa@Moxa:~# dpkg-reconfigure gpsd

If necessary, you may edit the gpsd configuration file by hand; the file is located at /etc/default/gpsd.

However, Debian recommends against this, and there is the possibility that whenever the gpsd package is

updated you will lose your settings. If possible, use the dpkg-reconfigure command shown above.

4. After gpsd is configured, start the daemon:

moxa@Moxa:~# sudo /etc/init.d/gpsd start

5. You should now be able to fetch GPS data via /dev/ttyACM0 device node.

6. You may use AWK to parse and reorder the NMEA string format:

awk -F, '/\$GPGGA/ {print strftime("%Y-%m-%d "), $2, (substr($3,0,2) +\

(substr($3,3) / 60.0)) $4, (substr($5,0,3) + (substr($5,4) / 60.0)) \

$6, $10; fflush();}' /dev/ttyACM0

7. You may also install the GPS test clients cgps and xgps, which can beu used to query gpsd:

Moxa:~# apt-get install gpsd-clients

8. Xgps is used on the desktop, and cgps is used on the command line terminal, or over a serial

emulator/interface. You may access either client by logging in remotely, using SSH or a virtual desktop. To

get a basic report on the current GPS data, call cgps on the console:

moxa@Moxa:~# cgps

and you should a report that looks something like this:
