GPS信号对流层延迟改正新模型研究

New Model for Tropospheric Delay Estimation of GPS Signal

  • 摘要: 为削弱对流层对GPS精密定位的影响,从大气折射率入手将大气分为3层,建立了大气折射率模型,并导出了对流层天顶延迟模型。利用IGS跟踪站的实测数据进行了验证,实验证明了新模型的有效性。

     

    Abstract: A new tropospheric zenith delay model is proposed based on a 3-layer partition of atmosphere and real observation data from regional GPS network are used for the performance testing. It is shown that the accuracy of tropospheric delay estimation are better in CHDU, KUNM and LAHS stations using the proposed model than Hopfield and Saastamoinon models.
