| 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。通过仿真方法对中国区域用户定位性能受电离层闪烁影响的情况进行分析研究。结合电离层闪烁模型、卫星导航接收机模型和用户定位算法，仿真了中国区域内卫星导航系统用户在电离层闪烁存在情况下的定位精度性能。仿真结果表明：电离层闪烁将引起用户接收机测量误差的增大，在受电离层闪烁影响严重的中国低纬地区，用户定位误差将有明显增大，严重时可能出现定位异常。

| Abstract: | Ionospheric scintillation is one of the threats to GNSS.Scintillation effects on users in the area of China are studies based on simulation.Combining the ionospheric scintillation model with the receiver models and algorithms in user positioning,the positioning performance of GNSS could be simulated under scintillation conditions.It is found that the preciseness of receiver measurements will be affected,and the positioning accuracy will be degraded apparently under scintillation conditions in the low latitu... |
