Hello Guys and Gals, I hope you all are doing great. This post will help you a lot understanding ACARS Message which is an acronym for Aircraft Communications Addressing and Reporting System which is a digital communications system that aircraft use to send and receive short messages to and from ground stations. So, let’s get started.

What is ACARS?

As I have mentioned ACARS Stand for Aircraft Communications Addressing and Reporting System which is a digital communications system. Standard ACARS transmits at a frequency of 131.550 MHz, which is in the receivable range of the RTL-SDR. The RTL-SDR software radio can be used as a radio scanner for listening to these digital messages, and with the help of some decoding software, can be used to decode and display the messages. The messages you can receive will be from nearby aircraft and ground stations. Most messages will be unreadable data intended for computers, but you can find out what is flying near you by decoding the flight number and aircraft registration details sent with every message.
