相位中心改正模式的转变对GPS数据处理的影响

Impact on GPS Data Processing of Changing fom Relative Phase Center Corrections to Absolute Phase Center Corrections

    摘要
  • 摘要: 总结了大地测量和天体测量对SVLBI卫星的要求条件,分析了GNSS系统和SLR系统以及中继卫星对卫星的定轨精度、地面测控站对SVLBI卫星的跟踪效率,研究了SVLBI卫星对射电源的访问效率,及其与地面VLBI测站和VSOP2卫星形成的地-空和空-空基线观测射电源的分辨率等,以此为基础设计我国SVLBI卫星的轨道参数。

     

    Abstract: In precise GPS data processing,absolute antenna phase center correction model has much advantage with relative model. When using different antenna phase center correction model,it has impact on GPS results. After analyzing the results of a city's CORS GPS data processed by Bernese GPS software,we find that coordinate in height various at a cm level,net scale factor changed 6.4 ppb,difference of troposphere ZPD value is -6.9±4.0 mm.
