摘要
精密单点定位测量技术已广泛应用于测绘、交通、市政、导航等诸多领域,随着我国BDS的顺利组网,基于BDS的精密单点定位技术研究越来越广泛深入.本文利用MGEX数据网站获取不同测站的多卫星系统的观测数据,建立双系统组合单点数据处理模型,通过对比BDS+GPS、BDS+GLONASS、BDS+Galileo三种组合模型的静态、动态精密单点数据处理结果,从位置精度、可见卫星数、DOP值等多个维度说明BDS+GPS组合的精密单点定位性能最优,可为BDS在实际定位测量工作中的应用提供参考.
Abstract
The precision single point positioning measurement technology has been widely applied in many fields such as surveying and mapping,transportation,municipal administration,navigation,etc.With the smooth networking of BDS in our country,the research on precision single point positioning technology based on BDS is becoming more and more extensive and in-depth.The MGEX data website is used in this article to obtain observation data from multiple satellite systems at different stations,and a dual system combination single point data processing model is established.By comparing the static and dynamic precision single point data processing results of the BDS+GPS,BDS+GLONASS,BDS+Galileo combination models,it is demonstrated that the BDS+GPS combination has the best precision single point positioning performance from multiple dimensions such as position accuracy,number of visible satellites and DOP value.This can provide reference for the application of BDS in practical positioning and measurement work.
