Toolchains

GNU Radio, gqrx, SDR#, CubicSDR, and the SoapySDR abstraction layer cover the desktop side. Python wrappers (pyrtlsdr, SoapySDR-Python, scikit-dsp-comm) make signal processing scriptable end-to-end.

Use cases

ADS-B aircraft tracking, NOAA weather satellite reception, ham radio digital modes, GSM/LTE security research, IoT protocol reverse-engineering, and wideband spectrum monitoring.
