| 摘 要： | 电离层闪烁是影响卫星导航系统定位性能的重要因素之一。电离层闪烁可造成GNSS载噪比降低，测量误差增大，载波周跳次数增多，电离层修正精度降低，定位用精度因子变大等影响。中国南方区域是全球电离层闪烁多发区之一，电离层闪烁影响的时空范围和程度较大，是我国卫星导航应用应关注的问题。针对电离层闪烁影响，提出了我国卫星导航系统应用中可行的针对性减缓措施。

| Abstract: | Ionospheric scintillation is one of the main threats to GNSS performance,including the shading on carrier-noise ratio,degradation of measurement precision,more frequent cycle-slips,degradation of accuracy in ionospheric delay correction,and variation of DOP etc..Frequent occurrence and its extensive spatial and temporal variation make scintillation a concern for GNSS applications in south of China,one of the most impacted areas in the world.Countermeasures were proposed for GNSS applications in China. |
