摘要
摘要:地磁暴期间，电离层可出现不同程度的扰动，显著影响GNSS导航系统性能.本文针对GNSS系统应用需求，全面分析了不同等级磁暴主相期间GPS单频点定位精度在中国区域（地磁中、低纬地区）的受扰情况.结果表明，定位误差极端值的出现概率与磁暴等级呈正相关，也与测站纬度相关（低纬一般高于高纬），定位精度在U（垂直）方向受影响程度明显强于其他方向，且在磁暴恢复相期间定位精度也可能受到显著影响.上述研究结果对了解磁暴期间中国区域（地磁中、低纬地区）GNSS应用性能、北斗三号全球系统在中国区域的应用性能及系统升级和中国区域电离层扰动特性研究有参考价值.

Abstract:Geomagnetic storms can induce different levels of ionospheric disturbance, which can make prominent impacts on the performance of GNSS applications. In this study, the influence on the accuracy of GPS single frequency standard point positioning (SPP) in China (geomagnetic low and middle latitudes) during the main phase of different classified geomagnetic storms was comprehensively investigated with requirements of GNSS system application. The results demonstrated that the probability of the extrema in positioning errors was positively correlated with the level of geomagnetic storms. That is correlative with the latitude of stations (lower latitudes is generally higher than for higher latitudes) as well. The influence on the positioning errors in U (vertical) directions was evidently stronger than in other directions. In addition, the positioning errors could be influenced noticeably during the recovery phase of geomagnetic storms. The finding in this study could provide a reference to the performance of GNSS applications, the performance of applications and related improvements of Beidou global navigation satellite system (BDS-3) and the study of ionospheric disturbance attributes in China (geomagnetic low and middle latitudes) region during geomagnetic storms.
