MapQuest for Android

Finally a voice-guided, turn-by-turn navigation app for Android using the OpenStreetMap project.

• Absolutely FREE – There’s no trial period, subscription, or upgrade necessary. You get all these capabilities absolutely free!
• Voice-Guided/Turn-by-Turn Navigation – Your phone speaks to you, telling you when to make a turn.
• Voice Search – Speak your destination or your search, for hands-free input.

I have had a chance to have a bit of a play with this app, but it still needs little on things like being able to select already cached OSM map data from sdcard that has already been downloaded, the ability to access to Contacts, and have favourite list or personal POI (points of interest) or starred have ever you like to refer to it as. For a beta app it seems to be rather stable on the HTC Desire.


Setting up NTP to update from a GPS

This is just a quick how to to setup NTP to update from a GPS

Installing software needed for the GPS:

If you already not done so connect the GPS to your computer you are wanting to run it on and confirm it is connected with lsusb

$ lsusb

My GPS is a USGlobalSat BU 353

Now to configure gpsd:

# dpkg-reconfigure gpsd

There just a few questions to answer.
First question asks you if you like to have gpsd to start at boot, I answered YES
Second question ask you to were tthe GPS is connected, in my case it was /dev/ttyUSB0

USGlobalSat BU-353 GPS under Linux

I have noted that this GPS unit has a prob when been powered off for ~72+ hours. The problem is that it resets itself back to binary mode, the quick way to tell this is there is no LED activity on the side of the unit. This unit optimally needs to be run in NMEA mode. To get this unit in to running in NMEA mode is very easy, while the unit is plugged into your computer you just have to issue it a command.

The command string to issue to it is:

$ gpsctl -n -s 4800 -t SiRF binary /dev/ttyUSB0

After running the above command you’ll notice that the LED on the side has come alive and will be steadily flashing. Now you’ll beable to use your GPS unit to its full potential.

For further info and help:

$ man gpsctl
