CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe paper presents a Software-Defined Radio (SDR) Telemetry, Tracking & Command (TT&C) transponder for Low Earth Orbit (LEO) satellites, named STAR. STAR implements A/D and D/A conversion at IF and baseband digital signal processing for telecommand reception and telemetry transmission, i.e., multi-standard (de)modulation, channel (de)coding, and control. An S/X-band transceiver is connected to the IF ports of STAR for RF frequency up/down conversion. Preliminary results for a proof-of-concept FPGA implementation are presented.
