摘要: 基于北斗官方发布的承载精密单点定位(PPP)服务的PPP-B2b信号与南方测绘最新研发高精度定位终端,本文采用全国6个城市连续一周的观测数据和实时定位结果,分析了基于PPP-B2b服务的PPP精度。其中重点分析了实时静态PPP与实时动态PPP定位的精度。试验结果如下:基于PPP-B2b服务的静态PPP定位精度水平方向优于7 cm,高程方向优于10 cm;基于PPP-B2b服务的动态PPP定位精度水平方向优于10 cm,高程方向优于15 cm。试验结果表明,基于该服务的实时PPP能达到静态厘米级、动态分米级的定位精度。

Abstract: Based on the officially released PPP-B2b signal by BeiDou, which carries the precise point positioning(PPP), and the latest high-precision positioning terminal developed by South Surveying & Mapping Technology Co., Ltd.(SOUTH), this article utilizes observation data and real-time positioning results of 6 cities across the country for a week to analyzes the accuracy of the PPP results based on PPP-B2b service. In this paper, the focus is on analyzing the accuracy of real-time static PPP and real-time dynamic PPP positioning. Experimental results show that the static PPP positioning accuracy based on the PPP-B2b service is better than 7 cm in the horizontal direction, and better than 10 cm in the vertical direction; the dynamic PPP positioning accuracy based on the PPP-B2b service is better than 10 cm in the horizontal direction, and better than 15 cm in the vertical direction. A conclusion can be made that the precise point positioning based on PPP-B2b service can reach centimeter level in static mode and decimeter level in dynamic mode.
