These messages contain multiple different types of messages along with data about the flight and the current conditions of the flight. +This project idea is to build a "simple" decoder to find out what each message contains and data from some of the messages! This is an advanced project, even when building a simple decoder due to how complex the ADS-B system is. You can take this project a lot further to put your skills to the test!
