Characterization of space radiation effects performance of advanced signal processors for earth observation application and the study of single event mitigation schemes

在过去的几十年里，卫星的能力越来越强。空间飞行任务采用了新技术。这些新技术大大提高了卫星的性能。就遥感卫星而言，趋势是朝向产生大量数据的更复杂和多传感器的有效载荷，以及朝向要求更好地提取信息和向用户迅速提供结果的用户应用。然而，这些数据的处理仍然主要在地面上进行，造成瓶颈，延迟时间较长，并且由于需要在航天器上进行高水平的数据压缩，信息数量和质量降低。未来的遥感应用将需要更丰富的信息内容和更快的传送速度。MDA Inc.已充分认识到这一问题，并建议机载处理是解锁这些应用程序的关键。在今后几年中，必须在雷达和光学任务中提出重要的机载处理，以便具有竞争力。然而，空间合格的航空电子设备往往落后于地面级航空电子设备的能力一个数量级。该研究项目将选择和评估适用于空间的强大地面级处理器，特别是地球观测卫星遇到的空间辐射环境。这项先进的研究将确定在空间辐射环境中用于机载处理的强大地面级处理器的性能，这有可能开启将遥感信息的力量直接带给最终用户的应用，绕过缓慢的地面处理。在这项高级研究期间，将培训一支高素质的人员队伍。萨斯喀彻温大学的研究人员将与MDA和加拿大国家粒子和核物理实验室（TRIUMF）的工程师和科学家合作开展这项工作。拟议研究的成果不仅将有助于加速目前对空间系统中单粒子效应的研究，而且还将使加拿大航天工业的空间系统设计者能够更有效地利用先进技术，同时确保系统更加可靠。

Over the past several decades, satellites have become more capable. New technologies have been adopted for space missions. These new technologies have significantly improved satellite performance. For remote sensing satellites, the trend is towards more complex and multi-sensor payloads that produce vast amounts of data, and towards user applications that require better information extraction and rapid delivery of results to users. However, the processing of this data is still done predominantly on the ground, creating bottlenecks, longer latencies, and reduced information quantity and quality due to the need for high levels of data compression on the spacecraft. Future remotely sensing applications will require even richer information content and faster delivery. MDA Inc. has fully acknowledged this issue and suggested that on-board processing is the key to unlock these applications. In years to come, significant on-board processing will have to be proposed in radar and optical missions in order to be competitive. However, space qualified avionics tends to lag terrestrial grade avionics by an order of magnitude in capability. This research project will select and evaluate powerful terrestrial grade processors suitable for use in space, in particular the space radiation environment, encountered by earth observation satellites. This advanced research will identify the performance of powerful terrestrial grade processors for on-board processing in the space radiation environment, which has the potential to unlock applications that will bring the power of remotely sensed information directly to end users, bypassing slow ground processing. A team of Highly Qualified Personnel will be trained during this advanced research. University of Saskatchewan researchers will perform the work in collaboration with engineers and scientists with MDA and Canada's national laboratory for particle and nuclear physics (TRIUMF). Outcome of the proposed research will not only help to accelerate current research on single event effects in space systems but also will enable space system designers in Canadian space industry to use advanced technology more effectively while ensuring more reliable systems.
