How To Decode L band Satellite ACARS and CPDLC messages with JAERO and your SDR

Published at : 23 Dec 2025

This video is part of the Monitoring Aviation Communications Series.

If you are interested in decoding ACARS signals from Inmarsat satellites, this episode will teach you what you need and how to do it.

Receiving signals from space is exciting, and monitoring Air Traffic Control CPDLC and general ACARS messages coming from far away is incredibly interesting.

I previously released an episode on VHF ACARS which provides further information on the types of messages typically received. It can be found at https://youtu.be/xGD_GFxH9ps

I used a NooElec SMArtee Software Defined Radio for the making of this video (link below). However you can use any SDR that has a bias tee output.
