利用高度角与MP组合随机模型提高PPP的收敛速度

Improving the Convergence Rate of PPP by Using the Combination Random Model of Height Angle and MP

在当前科学技术不断创新发展下,很多的技术都被应用到各个领域当中,其中精密单点定位技术(英文简称PPP)便是比较先进的技术,被当前地质勘察和航空测量广泛的应用。此次研究的目的是为了提高PPP收敛速度,这是由于当前PPP存在收敛速度比较慢的问题,不利于该项技术在科技发展领域的推广应用,针对这一问题,本文首先对多路径效应及MP组合观测值进行了实验分析,然后,对基于MP定权的GPS PPP方法进行详细的阐述,最后,通过实验分析,得出利用高度角与MP组合随机模型(ELE_MP模型)提高PPP的收敛速度。

With the continuous innovation and development of science and technology,many technologies have been applied in various fields.Among them,precise single point positioning(PPP)is a relatively advanced technology,which is widely used in current geological survey and aerial survey.The purpose of this study is to explore the use of high Angle combined with MP stochastic model to improve the PPP rate of convergence,this is due to the current PPP has the problem of slow convergence speed,is not conducive to the technology popularization and application in the field of science and technology development,in order to solve this problem,based on the analysis of actual orders,first of all to the multipath effect and MP combination experiment observation and analysis,and then,based on MP weighting for GPS precise point positioning method in detail,finally,the analysis to the experiment of the corresponding content,The result is to improve the convergence speed of PPP by using the combined height Angle and MP stochastic model(ELE_MP model).
