轨道遥感仪器和系统受益于高性能、适应性强的计算系统。基于现场可编程SRAM的门阵列（FPGA）通常是用于实时可重构计算的选择平台。这项技术是由商业部门推动的，因此用于空间环境的设备必须根据商业产品进行改造。总电离剂量，重离子和质子的特性已被用于在外延硅上制造的Virtex FPGA，以评估该技术预期的在轨辐射性能。主要的风险是单粒子翻转（SEU），因此翻转检测和缓解方案也进行了测试，以验证设备翻转灵敏度和翻转的系统后果的改善。
Orbital remote sensing instruments and systems benefit from high performance, adaptable computing systems. Field programmable SRAM-based gate arrays (FPGAs) are usually the chosen platform for real-time reconfigurable computing. This technology is driven by the commercial sector, so devices intended for the space environment must be adapted from commercial product. Total ionizing dose, heavy ion and proton characterization have been performed on Virtex FPGAs fabricated on epitaxial silicon to evaluate the on-orbit radiation performance expected for this technology. The dominant risk is Single Event Upset (SEU), so upset detection and mitigation schemes have also been tested to validate the improvement in the device upset sensitivity and the system consequence of upsets.
