在提供对空间实验有效载荷的远程访问方面存在许多独特的挑战。太空船的带宽有限、无法物理监控和探测有效载荷以及对参与该项目的各个研究人员的访问时间的管理，这些因素都创造了一个充满挑战的工作环境。可配置容错处理器（CFTP）项目旨在缓解与远程有效载荷操作相关的许多困难。我们使用了模块化FPGA设计，这使我们能够只传输小的应用程序模块，而不是完整的配置文件。这大大降低了上传新应用程序所需的带宽，因为我们发现了CFTP发布后的新实验。CFTP项目的另一个独特之处是其开发过程中的协作努力。我们必须管理全国各地的大学和研究机构在CFTP上运行实验、下载CFTP文件和分析发射后遥测数据的访问时间
There are many unique challenges associated with providing remote access to space experimental payloads. The limited bandwidth to the space craft, the inability to physically monitor and probe the payload, and the management of access time for various researchers working on the project all compound to create a challenging work environment. The configurable fault tolerant processor (CFTP) project aims to alleviate many of the difficulties associated with remote payload operation. We have made use of modular FPGA design, which allows us to transfer only small application modules rather than full configuration files. This dramatically reduces the bandwidth required to upload new applications as we discover new experiments for the CFTP after launch. Another unique aspect of the CFTP project is the collaborative effort in its development. We must manage access time for universities and research institutions across the country for running experiments on the CFTP, downloading CFTP documents, and analyzing telemetry after launch
