利用APPS-PPP、CSRS-PPP和GAPS-PPP三种在线GPS精密单点定位（PPP）软件处理了不同纬度地区以及太阳耀斑爆发生期间的IGS跟踪站数据。通过对处理结果的精度分析可知：三种处理软件单天解在E、N、U三个方向上的精度均优于3.5cm,且三个坐标分量上的互差不超过1.5cm;在太阳耀斑发生期间的定位精度没有明显降低。
利用APPS-PPP、CSRS-PPP和GAPS-PPP三種在線GPS精密單點定位（PPP）軟件處理瞭不同緯度地區以及太暘耀斑爆髮生期間的IGS跟蹤站數據。通過對處理結果的精度分析可知：三種處理軟件單天解在E、N、U三箇方嚮上的精度均優于3.5cm,且三箇坐標分量上的互差不超過1.5cm;在太暘耀斑髮生期間的定位精度沒有明顯降低。

In this paper, IGS data during solar flares and in different latitude areas were processed by three online-PPP processing softwares, i. e., APPS-PPP, CSRS-PPP and GAPS-PPP numerical results show that the accuracy of daily solution obtained by the three softwares is better than 3.5 cm on in the E.N,U directions, the solution differences from the three softwares in the three coordinate components are not larger than 1.5 era, the accuracy of precise point positioning during solar flares is not significantly degraded.
