Validation of a software‐defined baseband system for satellite telemetry and telecommand

This paper presents the validation of a software-defined baseband (SDB) system for satellite telemetry and telecommand (TM/TC). The was developed using open-source GNU Radio development kit. It runs on personal computer connected to commercial-off-the-shelf (CoTS) RF frontend. process performed by use mission-qualified emulator, state-of-the-art unit, orbiting satellites. is designed offer multimission support. Hence, it includes suite modulation schemes, line codes, matched filters, Consultative Committee Space Data Systems (CCSDS) forward error correction codes (convolutional, Reed–Solomon, concatenated, low-density parity-check [LDPC]) typically employed in TM/TC missions. figures merit used TM receiver are bit rate (BER) frame (FER). For TC transmitter, validated features index, power spectrum, physical layer operations procedures (PLOP). Graphical Abstract We present ground operations. Based low-cost radios, show minimal performance degradation laboratory environement. Infield tests shows that capable supporting
