A Design of Satellite Data Real-time Processing According to CCSDS Specification and FPGA Implementation

According to packet telemetry standard by Consultative Committee for Space Data Systems (CCSDS), this paper implements the design of data processing system for decoding frame and unpacking based on CCSDS data frame format on Field-Programmable Gate Array (FPGA) platform.The syetem includes three modules: decoding Transfer frame, decoding CFDP frame and unpacking module.The design takes advantage of the parallel processing characteristic of FPGA, which makes up the defects of data processing software in teal-time processing and IP(Intellectual Property) module reuse.The experimental result shows that the system can complete real-time decoding frame and unpacking of CCSDS data reliably and effectively and lays foundation for the realiability of the file transmission.
