Now we can show the corrected model for the process in Figure 7.
现在我们可用修正后的模型表示图7中的流程。
The main effect on the GPS signals of ionosphere and ionospheric refractive model are researched in this paper; then the dual-frequency corrected model of ionospheric refractive error is concluded.
研究了电离层对GPS观测信号的主要影响及电离层折射误差模型，总结了电离层双频改正模型。
