Dump1090 is a Mode S (ADS-B) message decoder for RTL-SDR USB radio receivers, written in C. It decodes aircraft transponder signals, displays detected aircraft in an interactive terminal view, and serves a live traffic map over an embedded HTTP server.

Use cases

• decode ADS-B aircraft signals from an RTL-SDR dongle
• track nearby airplanes on a live map in the browser
• stream Mode S messages over TCP port 30003
• decode raw IQ samples from a recorded file
• correct CRC errors in weak ADS-B messages
• build a low-cost aircraft tracking receiver

When to choose

• you have an RTL2832 SDR dongle and want a simple, minimal Mode S decoder
• you need robust decoding of weak signals with single-bit CRC error correction
• you want a self-contained tool with an embedded HTTP map server and no heavy dependencies

When to avoid

• you need a feature-complete decoder with Beast output, SDR driver abstraction, or active community support - consider forks like dump1090-mutability or readsb
• you don't have RTL-SDR hardware or Mode S radio signals to decode
• you need a maintained GUI application rather than a command-line tool
