ADS-B Spy2.2-RC26

Connect an Airspy R0, R2, or Mini and ADS-B Spy decodes aircraft broadcasts into an ADS-B receiving station on Windows. It processes the reception through the attached Airspy hardware instead of acting as a general-purpose radio program. The decoder supports MLAT operation at 12 MHz, 20 MHz, and 24 MHz, covering several operating modes for aircraft tracking.

ADS-B Spy is designed for an autonomous station that can run with low power requirements, making it suitable for continuous reception setups. Its original decoding algorithms are described as comparing favorably with those used in high-end ADS-B receivers. The focused audience is Airspy owners who want to collect and process ADS-B data rather than use their receiver for broader radio applications.

Typical uses include building a dedicated aircraft-monitoring station at home, operating a remote receiving point, or experimenting with ADS-B reception using compatible Airspy equipment. The current 2.2-RC26 release runs as an x86 executable on Windows, so its architecture is an important installation consideration. Airspy develops and publishes the software, which belongs to the System Tools category.
