中文说明:
利用GPS观测和精密星历,采用多项式或球谐函数模型的方法进行建模,能够同时估计接收和卫星DCB,在此基础山计算电离层TEC,为导航单位提供电离层延迟改正。
English Description:
Using GPS observation and precise ephemeris, using polynomial or spherical harmonic function modeling method, we can estimate the receiving and satellite DCB at the same time. On this basis, we can calculate the Ionospheric TEC and provide ionospheric delay correction for navigation units p>
