The next task for the RTL2832 was  to decode aircraft transmitting A-DSB using Ubuntu. Doug G4DZU had previously pointed me at a link http://www.hamradioscience.com/the-rtl-2832u-sdr-and-ads-b/ with an idiots guide to doing it , so it was time to try

.
Installing gnuradio took one line (and patience):-


wget http://www.sbrac.org/files/build-gnuradio && chmod a+x ./build-gnuradio && ./build-gnuradio
Buat directory


dinner and desert and a coffee later it finished. Time to see if it worked:-
  mkdir /usr/local/src/SDR
cd /usr/local/src/SDR


rtl_test -t

Persiapan

Buat directory

mkdir /usr/local/src/SDR
cd /usr/local/src/SDR

Instalasi paket pendukung

sudo apt-get install cmake swig libcppunit-dev python-cheetah doxygen \
libboost-all-dev python-sphinx fftw3-dev python-numpy libqwt-dev \
libusb++-dev libusb-dev libusb-1.0-0-dev libgsl0-dev python-wxgtk2.6 git qtcreator

Install GNURadio

Lakukan

cd /usr/local/src/SDR
git clone git://gnuradio.org/gnuradio

Compile

cd /usr/local/src/SDR/gnuradio
mkdir build
cd build
cmake ../
make
sudo make install
sudo ldconfig

Install rtl_sdr

Lakukan

cd /usr/local/src/SDR
git clone git://git.osmocom.org/rtl-sdr.git

Masuk ke directory rtl-sdr & lakukan

cd /usr/local/src/SDR/rtl-sdr/
mkdir build
cd build
cmake ../
make
sudo make install

Aturan udev yang penting agar USB dongle terdetek dengan baik perlu di copy menggunakan perintah berikut

cd /usr/local/src/SDR/rtl-sdr/
sudo cp rtl-sdr.rules /etc/udev/rules.d/40-basic-permissions.rules

Instalasi gr-air-modes

Lakukan

cd /usr/local/src/SDR
git clone https://github.com/bistromath/gr-air-modes.git
cd /usr/local/src/SDR/gr-air-modes/
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

Launching the programme with


uhd_modes.py -d -P 


with a piece of wire in the rtl283 antenna socket resulted in decodes from one aircraft almost overhead. Time for a better 1090MHz antenna. The J pole previously used was easy to build from 2 pieces of semi rigid cable so time to make another.It was tuned with a tracking generator/directional coupler/ spectrum analyser and achieved 32dB retun loss after tweaking. Putting this on the end of 35' of cable in the loft resulted in many more decodes and a torrent of data in the terminal:-


Next time to plot the data. The article pointed to Virtual radar server at http://www.virtualradarserver.co.uk/Mono.aspx so this was installed. Launching it with and clicking on the http link for local host resulted in the following map with 8 aircraft:-

The rtl2832 is not as sensitive as the Modesbeast I also have but it is only 5% of the cost!
