-====== Adding a u-blox MAX-7 GPS module ====== 
- 
- 
-====== What you need ====== 
-  * u-blox MAX-7 GPS breakout (we have [[http://ava.upuaut.net/store/index.php?route=product/product&path=59_60&product_id=52|one from HAP Supplies]]) 
-  * KDE Marble built with Python bindings 
- 
-====== How to get it working ====== 
-These instructions are valid for Ubuntu 13.10 but similar steps should work with other OSes. 
- 
-  * Attach the u-blox beakout to the expansion header by connecting the following pins (breakout -> Crazyflie expansion header): 
-    * GND -> DGND (pin 17) 
-    * VCC -> VCC  (pin 15) 
-    * TXD -> TX (pin 5) 
-    * RXD -> RX (pin 3) 
-  * Since the Python bindings for Marble isn't built by default you will have to build Marble from source and enable these (instructions taken from [[http://techbase.kde.org/Projects/Marble/MarblePythonInstructions|here]] 
-<code> 
-sudo apt-get install python-sip-dev python-qt4-dev 
- 
-git clone git://anongit.kde.org/marble.git ~/marble/sources -b KDE/4.12 
-mkdir -p ~/marble/build 
-cd ~/marble/build 
-cmake ~/marble/sources -DCMAKE_BUILD_TYPE=Release -DEXPERIMENTAL_PYTHON_BINDINGS=TRUE -DCMAKE_INSTALL_PREFIX=/usr/local 
-make 
-sudo make install 
-</code> 
-  * Make sure you have the correct firmware/software 
- 
-====== Tweaking and development ====== 
-There's no assisted GPS or battery backup so every time the Crazyflie is powered on the GPS module does a cold-start, which means that it takes at least ~30 seconds to get a fix. This will be improved in the future. 
- 
-Getting a position fix will not be as easy as with your phone, so make sure to be outside (or at least stick the Crazyflie a couple of meters outside the window).
