The 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.

Abstract
The 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.File in questo prodotto:
