全球卫星细分类型分析
根据卫星的用途、所处的轨道为标准,卫星可以细分为不同的种类。根据用途可以划分为地面观测卫星、通讯卫星、技术试验卫星、科学卫星、气象卫星等,根据卫星所处轨道的不同可以划分为近地卫星、地球同步轨道卫星、中轨道卫星、高椭圆轨道卫星、赤道轨道卫星等。
——全球存量卫星根据用途分类:通信卫星和地面观测卫星占绝大比例
美国忧思科学家联盟(union of concerned scientists)近期更新了他们的“在轨卫星统计数据库”。截至2018年4月底,在地球轨道上活跃运行的卫星数量为1980颗,同比上年增长13.92%。其中通讯卫星为792颗,同比上年增长6.7%,占卫星总量的42.0%;地面观测卫星661颗,同比上年增长10.9%,占卫星总量的35.0%;技术开发和示范卫星为213颗,占卫星总量的11.3%;导航定位卫星为121颗,占6.4%。
