隨著數位衛星通訊技術的快速發展，低軌道衛星通訊領域成為熱門的研究課題與技術發展方向，提供大量資料傳輸及全球通訊覆蓋的能力。太空資訊系統諮詢委員會 (Consultative Committee for Space Data Systems) 所制定之通訊標準明確給出太空任務間的數據交換和通信。其標準涵蓋了太空任務中之數據格式、通訊協定、錯誤檢測和修正等方面，為太空任務的成功執行提供了重要支持。基於本標準下實現之通訊傳輸能穩定進行資料數據交換，並以 FPGA 開發板實現，以適應不同傳輸環境的應用。 在本論文中，我們設計傳收機硬體架構並以 Verilog 硬體描述語言實踐，傳收機規格參考 CCSDS 所制定之 Telemetry 通訊標準，參考 DVB-T 架構之通道編解碼規格進行改良以及擴充。以上述規格開發出傳收穩定之收發機系統，且在 Zedboard 與 AD9361 平台使用天線進行收發。在資料控制上利用 PYNQ 實現軟體定義無線電平台與電腦間的資料傳輸。 ;With the rapid development of digital satellite communication technology, Low Earth Orbit Satellite (LEO) communication has become a popular research topic and technological development direction, offering extensive data transmission and global communication coverage capabilities. The Consultative Committee for Space Data Systems (CCSDS) has established communication standards that specifically address data exchange and communication among space missions. These standards encompass data formats, communication protocols, error detection and correction, providing crucial support for the successful execution of space missions. This research presents a comprehensive hardware and software solution for satellite communication, aligning with established standards and leveraging FPGA technology for efficient and reliable data exchange in space missions. In this paper, we design a transceiver hardware architecture implemented in Verilog Hardware Description Language (HDL). The transceiver specifications are based on the communication standards set by the Consultative Committee for Space Data Systems (CCSDS) and enhanced with the channel encoding and decoding specifications of the DVB-T framework.. The developed transceiver module ensures stable data exchange using communication transmission based on the aforementioned specifications, implemented on the Zedboard & AD9361 platform with antennas for transmission and reception. Data control is achieved through PYNQ to enable data transmission between the Software Defined Radio platform and computer.
