Thanks to Andreas Reinhardt who have port my old acarsdec code to rtl_sdr (http://lists.osmocom.org/pipermail/osmocom-sdr/2013-July/000712.html) I gain interest back to acars decoding and decided to rewrite completely acarsdec and to add it some new features, in particular a rtl front end. So , I am please to announce the acarsdec 2.0 release :
https://sourceforge.net/projects/acarsdec
Acarsdec is an open source, multi-channels realtime ACARS decoder for Linux.
It features :
- up to four channels decoded simultaneously
- multi-threaded
- error detection AND correction (all one error corrected and some two errors)
- input from sound file , alsa sound card or software defined radio (SRD) via a rtl dongle
The 4 channels decoding is particularly useful with the rtl dongle. It allows to directly listen simultaneously to 4 different frequencies. Ie:
acarsdec -r 0 131.525 131.725 131.825
Will decode acars on 3 frequencies with the rtl dongle number 0.
try and enjoy
