h1. ADS-B receiver with gr-air-modes and Google Earth

In this example, we propose to demodulate "ADS-B":http://en.wikipedia.org/wiki/Automatic_dependent_surveillance_%E2%80%93_broadcast transponders thanks to a module available at https://github.com/bistromath/gr-air-modes. Its installation can be performed thanks to PyBombs which should be already installed if you followed our [[UHD and GNURadio installation|installation guide]]. In a first step, go into your PyBombs directory and issue the following instruction:

<pre>

sudo ./pybombs install gr-air-modes

sudo ldconfig

</pre>

In a second step, Google Earth can be installed on GNU/Linux Debian like systems by

<pre>

sudo apt-get install googleearth-package

make-googleearth-package

dpkg -i google_earth_XXX.deb

apt-get -f install

</pre>

You can start decoding live signals from airplanes with the following instruction:

<pre>

modes_rx -A RX2 -K aircrafts.kml

</pre>

The output file @aircraft.kml@ can be interpreted by Google Earth (@Add > Network File@).
