An ADS-B decoder described as a swiss knife for decoding aircraft data. This project is a fork of Mictronics' readsb and supports various Software Defined Radio devices such as RTL-SDR, HackRF, Bladerf, and PlutoSDR. It offers robust networking options including Beast/SBS protocols and JSON output, making it an ideal backend for global flight tracking systems like tar1090.
Main topics:
ADS-B decoding via SDR hardware
Extensive network connectivity support (Beast, SBS, JSON)
Integration with mapping tools like tar1090
Support for multiple SDR device types

Friend or Foe is an open-source Android app that identifies aircraft and drones in real time using augmented reality. It combines ADS-B data, FAA Remote ID, WiFi analysis, and visual detection to overlay labels on the camera view, providing information about flying objects overhead. The project was built using AI tools like Claude, Grok, Codex, and Gemini, showcasing the potential of AI-assisted development. It offers features like AR viewfinders, multi-source detection, smart classification, and a drone reference guide, all functioning without requiring accounts or API keys.
This software takes a dump1090 stream of ADS-B messages and plops them into a sqlite database with a timestamp.
Mode-S demodulator written in C++ with CRC-based message framing. Stream1090 is a proof of concept implementation taking a different approach in order to identify mode-s messages in an SDR signal stream. Most implementations look for the so-called preamble (a sequence of pulses anounncing a message). Stream1090 skips this step and maintains directly a set of shift registers. Based on the CRC sum and other criteria, messages are being identified. The hope is that in high traffic situations, a higher overall message rate can be achieved compared to a preamble based approach.
This page details the ADS-B emitter categories as defined by DO-260B standard, used to classify aircraft and other airborne objects.
