FPGA-based ADS-B signal decoder

Real-time 1090MHz Mode-S demodulation and decoding on hardware.

This repo contains gateware used to receive and decode ADS-B messages on a Gowin Tang Nano 20K FPGA.

This project is documented in more detail on my website.

Demo

Decoded aircraft telemetry being streamed in real-time.

Tools / Dependencies:

This project is built entirely using open-source FPGA dev tools.

• Python - Various scripts and tooling
• Numpy - To process the samples used for simulation.
• OSS CAD Suite - Complete FPGA build flow
• cocotb - Testbench generator
• Verilator - Simulation (driven by cocotb)
• Surfer - Waveform viewer
