【摘要】：在分析参考站网各基线上对流层延迟信息性质的基础上,提出一种修正流动站对流层改正数高程方向偏差的方法,利用高程信息对流动站对流层改正数高程方向偏差进行修正。采用美国CORS网的6个参考站及香港SatRef网的7个站观测数据进行实验分析。结果表明,该方法能有效修正流动站对流层改正数在高程方向上的偏差,在100m以上高程差异条件下取得良好效果,使对流层改正数精度维持在cm级。
[Abstract]:Based on the analysis of the properties of tropospheric delay information on each baseline of the reference station network, a method for correcting the elevation deviation of tropospheric corrections in mobile stations is proposed. The elevation deviation of tropospheric corrections of mobile stations is corrected by using elevation information. The experimental data of 6 reference stations in the United States CORS net and 7 stations in Hong Kong SatRef network are used to carry out experimental analysis. The results show that, This method can effectively correct the deviation of tropospheric corrections in the elevation direction of the mobile station, and obtain good results under the condition of elevation difference above 100m, so that the accuracy of tropospheric corrections can be maintained at the level of cm.
