GPS网络RTK流动站的对流层内插改正分析

The analysis of tropospheric delay model for GPS net RTK

介绍网络RTK常规内插模型,分析内插法的精度,从单站上分析高程对天顶距延迟的影响,分析高程差异对双差对流层延迟的影响,利用网络RTK内插法只可消除其中大部分的误差。这对利用网络RTK算法生成流动站的误差改正数具有重要的参考价值。

The interpolation models are described in the article and their accuracy are analyzed in the GPS network.It not only analyzed the effects of the elevation on the zenith delay of one station,but also analyzed the effects of the difference of the elevation on the double-differenced tropospheric delay of two stations.The algotirhm can only eliminate most of the error.It has important reference value to generate the error correction of the rove stations.
