ADS-B Decoding Guide

This is a small research project conducted by Junzi Sun at TuDelft. While we were trying to work with ADS-B data collected from our receiver, we notice that there are very few documents available which can explain the ADS-B data comprehensively. So, we created this guide, along with a decoder written in python ( Have Fun!

The main focus of the guide is on reading different types of messages, understanding the information in the message, and decoding/computing aircraft status.
