[Portmanteau of Read ADSB]

Readsb is a Mode-S/ADSB/TIS decoder for RTLSDR, BladeRF, Modes-Beast and GNS5894 devices. As a former fork of dump1090-fa it is using that code base but development will continue as a standalone project with new name. Readsb can co-exist on the same host system with dump1090-fa, it doesn't use or modify its resources. However both programs will not share a receiver device at the same time and in parallel.

This version uses Googles protocol buffer for data storage and exchange with web application. Saves up to 70% in storage space and bandwidth.

This is a personal, hobbyist project with no commercial background.

❗ This version of readsb is not compatible with any prior version.

❗ This version of readsb is not compatible with any third party software or script that requires JSON output for statistical or aircraft data.

readsb tries to connect to a listening server, like a push server.

For example feeding adsbexchange.com use the parameters:

--net-connector feed.adsbexchange.com,30005,beast_out

Selectively forwards beast messages if the received data hasn't been forwarded in the last 125 ms (or --net-beast-reduce-interval). Data not related to the physical aircraft state are only forwarded every 500 ms (4 * --net-beast-reduce-interval).The messages of this output are normal beast messages and compatible with every program able to receive beast messages.

See INSTALL for installation and build process.
