基于CCSDS标准的卫星数据处理软件设计

摘要

根据空间数据协商委员会（ CCSDS）制定的分包遥测数据格式标准，航天器可以利用有限的信道资源，合理、分时地将遥测信息向地面传输。这对遥测数据处理软件提出了更高的要求。针对此问题，结合CCSDS标准，文章提出了一种解帧和解包实现方案，设计了适用于某卫星的数据处理软件，完成了对CCSDS数据的解析。实验表明，该数据处理软件可高效可靠地完成科学数据的解帧和解包操作。%According to the CCSDS criterions of the telemetry data format, spacecraft can use limited channel resource to transmit telemetry data reasonably from outer space to ground station by time-sharing. This brings about new higher requirements for data processing software. To deal with this problem, we proposed a data processing solution for decoding frame and unpacking, and then designed data processing software for a particular satellite based on the CCSDS criterions. Experimental results show that our data processing software can complete decoding frame and unpacking of scientific data effectively and reliably.
