TangoGPS is one of the applications that runs on the Openmoko Phones. For a list of all applications, visit Applications

TangoGPS is a map application which can utilize Neo's built-in GPS to show your current location.
Website: http://www.tangogps.org
From the freerunner connected to the internet:
opkg install gpsd
NOTE: I experienced hangups if gpsd was not installed. |
opkg install http://www.tangogps.org/downloads/tangogps_0.9.3-r1_armv4t.ipk
If opkg complains about not being able to acquire a lock, try:
pkill packagekit
To get gpsd working on the FreeRunner you have to change the configuration according to Gpsd#GPS_on_GTA02. Then start gpsd by:
/etc/init.d/gpsd start
If you get an error about no GPS device in /etc/default/gpsd execute:
echo "GPS_DEV=\"/dev/ttySAC1\"" > /etc/default/gpsd
Now you must power up the GPS-chip by opening the "Settings" application and setting the GPS entry to "on". Now you can run tangoGPS and wait until it get's a GPS fix. This can take up to a few minutes.
Tangogps is a very nice GPS mapping application. The latest version is available in Debian.
It depends on gpsd which conflicts with frameworkd in fso-frameworkd, but there is a package available that provides the gpsd interface to clients while using the services of the FSO frameworkd daemon, fso-gpsd. To install tangogps run
# apt-get install fso-gpsd tangogps
To turn the gps on, you have two options. You can start the gps application in Zhone, this will turn on the gps device for you or you can manually turn on the gps device using
# echo 1 >/sys/devices/platform/s3c2440-i2c/i2c-adapter/i2c-0/0-0073/neo1973-pm-gps.0/pwron
Issues:
tangoGPS can bunch-download the map images so you don't need an internet connection while walking around. By default tangoGPS stores downloaded maps to /tmp/. This folder is lost every time you reboo the device. But you can use the "Config" tab within tangoGPS to change the "Cache Dir" location to , for example, /osm/ . So downloaded maps will be kept in the Neos flash, also after reboot. This works fine on OM2007.2 and Debian. If this config gets lost during reboot file a bug against your distro.
Once you have set the location to a non-volatile path, you can connect your Neo to the internet by USB or WiFi at home and start downloading the maps of your area. Tap the map screen and select "map download". Now on-the-road tangoGPS will be able to show you maps in different zoom levels even though you are not connected to the inet.
I think TangoGPS may have started working after I followed the instructions to get GPRS working with GSM multiplexing here: Manually_using_GPRS#Option_1:_With_GSM_multiplexing_and_with_a_GUI
There are steps included in those instructions to improve GPS performance. The great thing is that once you get GPRS working, you can roam with TangoGPS running and have it download maps as needed over the GPRS connection!
TangoGPS works fine to create track for Openstreetmap. However, it records and stores a track in its native format, use [1] (see also: tools to convert the track to GPX (i.e to import into Josem):
perl convert2gpx.pl 20080903_111508.log > 20080903_111508.gpx
TangoGPS does not support the import of tracks. You may help yourself by using this tool to import GPX trackpoints as a series of POIs directly into the sqlite database which tangoGPS uses to store POIs.
Go to Config and change the url to http://mt1.google.com/mt?&x=%d&y=%d&zoom=%d and check the "Inverted Zoom" box. Press save Repository Configuration and you're ready to go.
