【摘要】：在分析參考站網(wǎng)各基線上對流層延遲信息性質(zhì)的基礎(chǔ)上,提出一種修正流動站對流層改正數(shù)高程方向偏差的方法,利用高程信息對流動站對流層改正數(shù)高程方向偏差進行修正。采用美國CORS網(wǎng)的6個參考站及香港SatRef網(wǎng)的7個站觀測數(shù)據(jù)進行實驗分析。結(jié)果表明,該方法能有效修正流動站對流層改正數(shù)在高程方向上的偏差,在100m以上高程差異條件下取得良好效果,使對流層改正數(shù)精度維持在cm級。
[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.
