Berkeley SETI Research Center (home to the Breakthrough Listen Initiative) and the SETI Institute (administrators of the Allen Telescope Array) are carrying out world-leading programs to search for intelligent life beyond Earth. These searches use cutting-edge digital signal processing hardware to characterize the "haystack" of human-generated radio signals in search of the "needle" of a signal from elsewhere. A growing collaboration with the GNU Radio community has led
to the deployment of GNU Radio hardware and processing pipelines at radio telescope sites, collaborations with industry partners to develop innovations in signal processing and analysis techniques, new programs to educate the next generation of radio scientists and engineers, and the opportunity for volunteers to get hands-on with some powerful and fun!) hardware. The increasing collaboration has also led to the SETI Institute, a 501(c)(3) nonprofit, managing contracts, grants, and administration for GNU Radio.
