By means of 4 dual - frequency gps receivers over china , the tec in the ionosphere during solar flare on nov 22 , 1998 is calculated . the results indicate that the flare , the x - ray level of which is x3 . 7 , cause obvious tec enhancements in the ionosphere , the largest tec enhancement caused by the flare is about 1 . 25 tecu . the characteristic of this method to study such ionospheric disturbances caused by flares is analyzed . it is concluded that this method can be used to study the ionosphere disturbances caused by solar flare , and can get more ionospheric disturbances information because of the special satellite constellation
此次耀斑爆发引起了设在北京的高频多普勒长达15min左右的无线电短波中断。通过对gps得到的电离层tec进行分析发现：此次耀斑造成了大面积的电离层tec的增加，耀斑爆发引起的最大tec增幅在1 . 25个tec单位左右利用高精度的gps数据处理方法可研究耀斑引起的电离层扰动。另外，还分析了由gps计算的tec的时空变化特点。
