Tracking Aircraft with Software-Defined Radio
summary
A live setup captures ADS-B using an RTL-SDR USB dongle tuned to 1090 MHz and feeds decoded messages from dump1090 → Redis stream into a websocket-backed web map. Aircraft broadcast dozens of messages per second; an antenna polarization change doubled reception and many messages lack position fields, which breaks some markers — demo shows real-time tracks (Ryanair seen) and a working pipeline of SDR → parser → Redis stream → websocket → map.
