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 libfftw3-dev python-numpy libqwt-dev \
libusb-dev libusb-dev libusb-1.0-0-dev libgsl-dev python-wxgtk3.0 git qtcreator

Install UHD + GNURadio

Compile SWIG

sudo su
sudo apt-get install bison flex
cd /usr/local/src
git clone https://github.com/swig/swig.git
cd swig
sudo apt-get install automake
./autogen.sh
./configure
make
make install

Compile UHD

mkdir -p /usr/local/src/SDR
cd /usr/local/src/SDR
git clone https://github.com/EttusResearch/uhd
cd /usr/local/src/SDR/uhd/
git tag -l
git checkout v3.15.0.0
cd host
mkdir build
cd build
cmake ../
make
make test
sudo make install
sudo ldconfig
export LD_LIBRARY_PATH=/usr/local/lib

Compile GNURadio

cd /usr/local/src/SDR
git clone --recursive https://github.com/gnuradio/gnuradio.git
cd gnuradio
git checkout maint-3.8
git submodule update --init --recursive
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../
make
make test
sudo make install
sudo ldconfig

Install rtl_sdr

Lakukan

cd /usr/local/src/SDR
git clone git://git.osmocom.org/rtl-sdr.git
cd /usr/local/src/SDR/rtl-sdr/
mkdir build
cd build
cmake ../
make
sudo make install
sudo ldconfig

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
/etc/init.d/udev restart

Kita dapat meng-unplug & replug USB dongle. Cek menggunakan perintah

Catatan Antenna

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:-


Membuat Virtual Radar

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!
