基于对流层加权法的网络RTK快速初始化研究

Fast Initialization of Network RTK Based on Troposphere Weighted Method

提出了对流层加权法,根据站间高差对对流层参数进行约束,得到的相对天顶对流层湿延迟精度更高,降低了对流层对模糊度估值的影响,提高了模糊度浮点解的精度和收敛速度。实验结果表明,使用对流层加权法将初始化速度提高了约14.6%。

This paper proposes the troposphere weighted method,in which the zenith tropospheric delay parameters are constrained according to the height difference between two stations.Therefore,the estimated relative wet tropospheric delay is more precise,which reduces the effects of troposphere to ambiguities and improves the precision and convergence speed of float ambiguity solutions as a result. The experimental results show that the initialization speed is improved by 14.6%.
