gr-acars
A "simple" demonstration software for decoding ACARS, a low-bandwidth
communication protocol used by airplanes to communicate with airports.
Detailed description of the operating principles is available at
http://jmfriedt.free.fr/lm_sdr.pdf (French) and
http://jmfriedt.free.fr/en_sdr.pdf (English). See https://www.youtube.com/watch?v=54URhrJkk28
(SDRA 2020) for a discussion on the clock synchronization scheme.
The latest 2022 release for GNU Radio 3.9 and 3.10, following 3.8, named ng for
New Generation, aims at adding bitrate clock tracking + removes the external
dependence with libfftw by using the GNU Radio FFT wrapper. Doing so, multiple
ACARS decoding blocks can run in parallel.
Compile for x86 PC with:
cd 3.10ng
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr ..
make -j4
sudo make install
(developed and tested on Debian GNU/Linux)
Compile for RaspberryPi4/Buildroot (located in BR_PATH):
cmake -DCMAKE_INSTALL_PREFIX:PATH=$BR_PATH/output/target/usr -DCMAKE_TOOLCHAIN_FILE=$BR_PATH/output/host/share/buildroot/toolchainfile.cmake ../
make -j4
make install
Features
- RTL2832U based receivers, tuned to 131.725 MHz in western Europe (main ACARS channel)
- GNU Radio Companion compatible block
