摘要
目前,北斗三号全球卫星导航系统全面开通,支持BDS-3导航芯片、模块等的关键技术已经全面突破.作为一种高精度定位技术,精密单点定位(PPP)已经被广泛应用,与此相关的是,基于BDS-3的PPP定位研究已经成为当前研究的热点.本文选用MGEX跟踪站的实测数据,对比分析了BDS-2、BDS-3、BDS-2/BDS-3和GPS等4种不同PPP定位解算模式下的静态和动态PPP定位精度,结果表明,BDS-3卫星的加入明显提高了PPP定位精度,静态和动态PPP 3个方向的定位精度均有较大提升.
Abstract
Currently,the full operation of the Beidou-3 Global Satellite Navigation System has been successfully achieved with com-prehensively developed key technologies,such as BDS-3 navigation chips and modules. As a high-accuracy positioning technology,Precise Point Positioning (PPP) has been widely applied. Accordingly,research related to Beidou-3-based PPP positioning has be-come a hot topic. In this study,using measurement data collected from the MGEX tracking station,we performed comparative analysis of static and dynamic PPP positioning accuracy among four different modes of PPP positioning solutions:BDS-2,BDS-3,BDS-2/BDS-3,and GPS. The results indicated that the addition of BDS-3 satellite significantly improved PPP positioning accuracy with static and dynamic PPP positioning in three directions.
