我们研究了在单粒子效应发生期间，采用商用现货（COTS）技术开发的高性能星载计算机的在轨性能。该处理器在800公里高度的极轨道上在正常和太阳耀斑条件下都成功地工作和运行。在太阳耀斑期间，单个事件的发生率比正常情况增加了四倍以上。在太阳耀斑期间发生单一事件的地区蔓延到极地地区，而通常它们仅限于南大西洋异常（SAA）地区。我们的研究结果表明，我们的COTS处理器的性能是足够的未来的空间应用。
We investigated the in-orbit performance of a high-performance on-board computer developed with commercial off-the-shelf (COTS) technology in terms of its performance during the occurrence of single event effects. The processor worked and performed successfully both under normal and under solar flare conditions in 800 km altitude polar orbit. During a solar flare, the occurrence of single events increased by a factor of more than four compared with normal conditions. The area where single events occurred during the solar flare spread to the polar region, whereas normally they are limited to the region of South-Atlantic anomalies (SAA). Our results suggest that the performance of our COTS processor is sufficient for future space applications.
