基于PRIDE PPP-AR的精密单点定位精度分析

Accuracy Analysis of Precise Point Positioning Based on PRIDE PPP-AR

为充分验证PRIDE PPP-AR软件在精密单点定位解算方面的稳定性与精度,本文利用收集的134座HLJCORS基准站GNSS观测数据,同时采用PRIDE PPP-AR软件与高精度GNSS数据处理软件Bernese进行精密单点定位解算,通过解算坐标的分析可知,PRIDE PPP-AR软件在水平分量上与Bernese相差平均约4 mm,在垂直分量上基本一致。基于本文研究,在工程应用中可以优先考虑采用PRIDE PPP-AR软件,实现高效、快速、高精度定位的需求。

In order to fully verify the stability and accuracy of PRIDE PPP-AR software in precision single-point positioning solution,this paper uses the collected GNSS observation data of 134 HLJCORS,and uses PRIDE PPP-AR software and high-accuracy GNSS data processing software Bernese to perform precision single-point positioning solution.Through the coordinate analysis of the solution,the difference between the PRIDE PPP-AR software and the Bernese in the horizontal component is about 4 mm on average,and the vertical component is basically the same.Based on the research in this paper,the PRIDE PPP-AR software can be prioritized in engineering applications to meet the requirements of efficient,fast and high-accuracy positioning.
