Tracking Aircraft with Streams + Software-Defined Radio
summary
Claim: cheap USB radios plus free software capture real ADS‑B broadcasts and feed a live event stream that drives a map. Hardware: RTL‑SDR dongle and simple antenna; software: SDR Angel for receive, dump1090 to parse 1090 MHz ADS‑B frames, Node.js ingestor, and Redis Streams (Redis Stack) for event storage and search. Demo builds per‑aircraft JSON state, websockets and a map showing Heathrow/nearby flights (thousands of messages per minute for busy targets) and it works live.
