摘要
介绍计算硬件延迟的方法,采用电离层VTEC模型进行系统组合硬件延迟的参数估计;比较单站和多站建模的差异,并且对解算结果的准确性与稳定性与IGS公布的结果进行比较。计算结果与IGS的计算结果一致,表明修正硬件延迟后的电子浓度含量能较好地反映磁暴现象。
It mainly introduces the methods for resolving the differential code bias. Using the ionosphere's VTEC model to solve the combined differential code bias. Discussing the difference between the single sta- tion mode and the multiply station mode it compares the resulCs stability and the accuracy with the IGS. The results accord with the IGS. The TEC adjusted with the differential code bias reflects the magnetic storm very well.
