摘　　要：利用仿真方法研究了GNSS-R接收天线俯仰角、卫星轨道长半轴和轨道倾角对镜像反射点数量的影响,对4颗和6颗卫星组成的星座时空分辨率进行了仿真计算,分别获取了星座的时间分辨率。认为由6颗卫星组成的星座,8 h可完成全球5°×5°海洋格点的探测任务。The simulation method was employed for studying the impact of the antenna pitch angle and semi major axis on mirror reflection points.The spatial and temporal resolutions of GNSS-R ocean remote sensing satellite constellation which was composed of four and six satellites have been figured out.Constellation formed by 6 satellites has good coverage performance for global 5°×5° ocean grid on the eight hours time.
