The present contribution applies a modified version of a well‐known weak‐scatter scintillation model to the propagation paths between an Earth station and two geostationary satellites, as they are affected by drifting ionospheric irregularities detected by the planar Langmuir probe onboard the Communications/Navigation Outage Forecasting System (C/NOFS) satellite. This study considers one year of data from a limited altitude range, two longitude sectors and frequencies to analyze the mitigation effects from the angular distance between the geostationary satellites on the space diversity gain, considering the statistical distributions of the amplitude scintillation index S₄. The results indicate that the space diversity gain increases with the angular distance between geostationary satellites. However, once the angular distance between the geostationary satellites reaches a certain limit (approximately 20°), the space diversity gain no longer increases. Additionally, these gains are high at the L1 frequency and less impressive at an Ultra High Frequency (UHF). It is shown that these observations are consistent with the South American and Indian‐Asian equatorial and low‐latitude ionospheric environments, also characterized through the same data and the scintillation formulation.

C / NOFS平面Langmuir探针数据分析的基础上减轻空间多样性对电离层振幅闪烁的影响

本文稿对地球站和两颗对地静止卫星之间的传播路径应用了著名的弱散射闪烁模型的修改版本，因为它们受到通信/导航中断飞机上的平面朗缪尔探测器探测到的电离层不规则漂移的影响预报系统（C / NOFS）卫星。这项研究考虑了有限的海拔范围，两个经度扇区和频率上的一年数据，以分析对地静止卫星之间的角距离对空间分集增益的缓解影响，同时考虑了幅度闪烁指数S ₄的统计分布。。结果表明，空间分集增益随对地静止卫星之间的角距离而增加。但是，一旦对地静止卫星之间的角距离达到某个极限（大约20°），空间分集增益就不再增加。此外，这些增益在L1频率时很高，而在超高频（UHF）时效果不佳。结果表明，这些观测结果与南美和印度-亚洲赤道和低纬度电离层环境一致，并且通过相同的数据和闪烁公式也具有特征。
