Abstract The earlier developed alternative technique for calculating the ionospheric contribution into the full phase of the signal on the transionospheric paths of propagation, based on the perturbation theory in spherical co-ordinates with the spherically symmetric inhomogeneous zero-order approximation for the ionosphere, is further extended in order to apply it to the two-frequency mode of operation of GNSS. When doing this, the method itself is additionally validated and verified in the numerical experiment, where the reconstruction of the slant TEC calculated by the alternative technique for the two-frequency mode of operation is compared to that directly generated by the NeQuick model of the ionosphere.

计算电离层相位超前的新技术和测量电离层TEC的双频模式

摘要 基于球坐标中的微扰理论以及电离层的球对称非均匀零阶近似，早期开发的用于计算电离层对跨电离层传播路径上信号全相位的贡献的替代技术是进一步的发展。扩展以将其应用于 GNSS 的双频操作模式。这样做时，该方法本身在数值实验中得到了额外的验证和验证，其中将由双频操作模式的替代技术计算的倾斜 TEC 的重建与由电离层的 NeQuick 模型直接生成的进行比较.
