摘要

本文基于实时精确点定位(RTPPP)模型，利用国际GNSS服务(IGS)提供的包含状态空间表示(SSR)校正信息的实时Ntrip流广播星历校正，在RTKLIB软件上实现实时精确点定位和精度分析。静态和动态实验结果表明:在静态状态下，通过对广播星历进行SSR校正得到的精确星历和时钟误差可以在短时间内水平实现厘米级定位，垂直实现分米级定位。实时动态PPP定位精度达到分米级，无发散，非常可靠。

Analysis of static and dynamic real-time precise point positioning and precision based on SSR correction

This paper realizes real-time precise point positioning and implements precision analysis on RTKLIB software based on Real Time Precise Point Positioning(RTPPP) model of broadcast ephemeris corrections via the real-time Ntrip streams, which contains state space representation(SSR) correction information provided by International GNSS Service (IGS). The static and dynamic experimental results show: precise ephemeris and clock error obtained from SSR correction of broadcast ephemeris can realize centimeter-level positioning horizontally and decimeter-level positioning vertically in short time under static state. Real-time dynamic PPP positioning precision can reach decimeter-level with no divergence and is very reliable.
