FY—1C卫星空间粒子成分监测器及其探测结果

简要介绍了FY－1C星空间粒子成分监测器的任务目标、工作原理、创新特色及在轨探测结果。空间粒子成分监测器用于卫星轨道空间的带电粒子辐射监测，为卫星的在轨安全和抗辐射加固设计服务。监测器在世界上实现用1套传感器完成对高能电子、质子、α粒子至铁离子的全成分监测，使我国首次获得了870km高太阳同步轨道全空间的各种重离子分布、质子能谱分布和电子通量分布，捕捉到大量的地磁暴和太阳质子事件，获得了批重要的探测成果。

FY-1C Space Particle Composition Monitor and the Results Detected

It presents in brief the mission, principle, innovation and the results detected of the SPM (Space Particle Composition Monitor) onboard FY 1C satellite. The SPM is used to monitor space charged particles, serves orbital satellites' safety and radiation tolerance design. It has been realized firstly in the world to use a set of sensors to detect high energy electron, proton, alpha particle and all kinds of heavy ions simultaneously. According to the detected results of the SPM the space distribution of the heavy ions, proton and electron in sun synchronous orbit at 870 km altitude have been obtained. A multitude of magnetic storm and the solar proton events have also been monitored by the SPM.
