ESA OPS-SAT Mission: Powered by GNU Radio
summary
ESA’s OPS‑SAT is a 3U open innovation cubesat with a Lime LMS6002 SDR, Altera Cyclone V SoCs and a Nanomind OBC; a GNU Radio reference implementation (receiver, GMSK demod, AX.25/CSP decoder, ZeroMQ outputs and GUI) is published and used in ground stations in Ireland and Austria. The UHF link uses GMSK 9.6 kbps at 437.2 MHz with CCSDS scrambling and 32‑byte Reed‑Solomon; Doppler compensation uses GPredict. The implementation produces first beacon decoded by amateurs shortly after separation and is integrated into daily ops.
