Abstract
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.
