GNSS电离层掩星产品

云遥宇航自主研发的星载GNSS掩星探测载荷（GROI）接收来自GNSS导航卫星的信号，通过云遥宇航掩星数据处理系统（预处理软件GNROPP、反演软件GNROI）获取电离层中电子密度垂直廓线，电离层掩星总电子含量廓线产品可以提供电离层中总电子含量的垂直分布特征，同时得到F2峰值变化。

Developed independently by Yunyao Aerospace, the on-board GNSS occultation detection payload (GROI) receives signals from GNSS navigation satellites. Via Yunyao Aerospace's occultation data processing system, which includes the preprocessing software GNROPP and the inversion software GNROI, it acquires the vertical profiles of electron density in the ionosphere. The ionospheric occultation total electron content (TEC) profile products can provide the vertical distribution characteristics of total electron content in the ionosphere, and simultaneously retrieve the variations of the F2 peak.
