| 摘 要： | 从模型改正法和双频改正法两个方面阐述了目前对于在GPS数据处理中关于电离层延迟改正的两种思路,主要整理了Klobuchar模型的解算步骤,给出了双频改正的具体方法。并结合实测数据,分别用这两种方法对电离层延迟进行改正,然后与不用任何方法改正的解算结果进行比较,通过对比这两种方法对电离层延迟的改正效果,得出有益的结论。 |

| Abstract: | This paper briefly introduces two methods of ionospheric delay methods in GPS data progressing,namely Klobuchar model and dual-frequency correction,and summarizes the calculating steps of Klobuchar model,offers the exact method of dual-frequency correction.And then,combined with the measured data,the ionospheril delay is corrected with the two different methods.Finally,the paper compares the effects of these two correction methods on the ionospheric delay of positioning accuracy and draws a positive conclusion. |
| Keywords: | Klobuchar dual-frequency correction ionospheric delay GPS single-point positioning |
