 # ACARSDEC
 
-Acarsdec is an open source, realtime  ACARS demodulator and position decoder for Linux.

 Aircraft Communication Addressing and Reporting System (or ACARS) is a digital datalink system for transmission of small messages between aircraft and ground stations via VHF radio.

 ## HOW DOES IT WORK ?
 
 To receive ACARS you need at least an AM VHF air band receiver tuned to one of these frequencies:

 In this mode, acarsdec acts as a very basic local aprsd server.
 ACARS messages, and in particular, position report messages are converted to APRS format, so you can plot aircraft positions on a map.
 
 PS: position decoding is in experimental stage. Mail me if you find errors or lack of position reporting.
