利用差分参考站和用户相对于导航卫星位置不同,引起了电波穿越电离层处的垂直TEC和角度不同是产生这种残差的主要原因,提出了一种改进的伪距差分算法并给出了定位算法。-Using differential reference station and the user with respect to the different navigation satellite position, causing the radio wave through the ionosphere at vertical

GNSS定位代码，包括许多改正的代码模块，电离层改正，对流程改正等等十多个模块功能。-GNSS positioning code, including many of the correct code module, ionospheric correction, the process of correction and so on more than and 10 modules function

Klobuchar-电离层改成模型 这个行业里比较经典的电离层改正模型-Klobuchar- ionospheric modification model in the industry, the more classical ionospheric correction model
