| 摘 要： | 分析了网络RTK中基准站和流动站间气象元素、基线长度、高程差异和模型差异等因素对对流层延迟误差的影响,得出气象元素的大小和基线长度等与单差对流层延迟之间存在线性关系,由基准站和流动站的对流层模型差异造成的差值与高差之间也存在线性关系,且利用网络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.

| Abstract: | In this paper, characteristics which influence on troposphere delay by factors such as weather elements, altitude and model difference in GPS network RTK are analyzed in detail. A conclusion is that there are linear correlations between weather elements, baseline length and single difference troposphere delay. Different troposphere delay models can result in different single difference troposphere delays, the difference appears. It is also a linear correlation between the difference and the altitude. So, most of difference can be eliminated if interpolation algorithms of network RTK are used. It has a very important reference value when moving station correction terms are gained by using interpolation algorithms of network RTK. |
