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

验证用于卫星遥测和遥控的软件定义基带系统

本文介绍了用于卫星遥测和遥控 (TM/TC) 的软件定义基带 (SDB) 系统的验证。基带系统是使用开源 GNU Radio 开发工具包开发的。它在连接到商用现货 (CoTS) 射频前端的个人计算机上运行。验证过程是通过使用符合任务要求的卫星模拟器、最先进的基带单元和轨道卫星来执行的。基带旨在提供多任务支持。因此,它包括一套调制方案、线路码、匹配滤波器和空间数据系统咨询委员会 (CCSDS) 前向纠错码(卷积、Reed-Solomon、级联和低密度奇偶校验 [LDPC])通常用于 TM/TC 任务。用于验证 TM 接收器的品质因数是误码率 (BER) 和帧错误率 (FER)。对于 TC 发射机,经过验证的特性是调制指数、功率谱和物理层操作程序 (PLOP)。
