    Abstract
    基于FocusGEO望远镜2017年12月至2019年6月的测光观测数据,开展台站上空地球同步轨道(GEO)目标光度曲线的分类研究.通过对GEO卫星光度曲线特征的统计分析,建立了一种全新的GEO卫星分类系统,确定了各类GEO卫星光度曲线的占比,分析了光度特征类别与卫星平台的相关性.本研究将197颗GEO卫星的光度曲线分为六类,其中约90％的卫星可归为三类:典型类、BSS类和Ekspress类.光度特征分类与卫星平台无直接的相关性,但同一类别中平台相同或相近的卫星,具有相似的光度曲线.该分类系统可为位置相近的多个GEO目标的准确识别提供辅助手段,为目标异常监测和物理特性研究提供依据,对空间态势感知具有重要意义.
