Phase 4 Ground Station Project – Open Research Institute
Phase 4 Ground Station Project – Open Research Institute is a project to develop open source terminal (ground station) for future amateur satellite communications. “Phase 4” refers to the AMSAT phase system where Phase 4 is a Geostationary Earth Orbit (GEO) satellite. But the Phase 4 Ground Station Project has ambitions beyond satellite communications and expects that the work will find use in terrestrial applications (and that will probably be the first usage of the project before an amateur GEO payload is launched over the USA).
The Phase 4 Ground Station Project is a really interesting mix of new technology in amateur radio and is mainly based around SDR and gnuradio. Check it out and see if you can contribute!
